[Dib]

Dib groaned. He had been at it for hours at this point, with no relief in sight. His hand squeezed, tugged, even pinched and gripped tightly at some points, yet nothing could get him to the sweet release he’d been craving.

He had tried all forms of porn, even venturing to the more kinkier videos, yet nothing could get the hard on to even slightly deflate, much less get him off. He threw an arm over his eyes, his other arm dangling limply off the side of his bed.

He shut his eyes and tried to imagine the many other scenarios that had gotten him off before, and yet again, nothing worked.

His phone, which he’d long since abandoned, buzzed and began to glow in the dark, and Dib sighed and sat up, reaching for it and swiping his code in, grunting in annoyance as the message filled his screen.

Bug boy in all caps. He skimmed the long message. A threat to destroy him tomorrow and a very well hidden goodnight. Same old, same old, he thought, tossing his phone further down his bed.

He missed the message that threatened to come to him personally if he ignored Zim’s messages again. Dib crawled off his bed, erection bouncing as he walked towards his floating chair and pulling up a tab on his computer.

He felt his face flush as he typed in a couple strands of code, opening up a private search system made for the far outreaches of space. He knew in his gut that there was no going back from this.

In the past, when he’d first stumbled across the alien porno sites, he had immediately exited, disgusted and confused.

Now, his dick twitched at the sight of Irkens and Vortians bent over, alien species of all kinds frozen in frame with their monstrous-like cocks stuffed inside them.

He groaned and clicked the first video, featuring a small irken that looked similarly to Zim, however their antennae curled at the tips.

He flinched as the video began with loud chirps and clicking noises, quickly pressing the volume button on his keys to turn it down and pausing the video.

He glanced towards his door, expecting Gaz to start banging on his door any second. When nothing happened, he pressed play, his fingers sliding down the tip of his dick. He frowned at the sight of the Irken being fucked by a much larger irken, wishing it was an alien with a more fleshy tone.

Ignoring this, he focused on the reactions of the smaller irken. He realized from the pitch of her voice she was female, and while it was a bit of a turn off, he brushed past it.

Her stomach bulged with each thrust, her eyes fluttering open and shut as she struggled to maintain her composure despite the ruthless fucking. Dib knew he shouldn’t, but he let his mind wander.

Would Zim look like that if he fucked him? Dib wasn’t that much bigger than him, but surely once he grew up, he would be.

The thought sent a pleasantly dark chill down his spine and he began tugging his cock in earnest.

He imagined the scene: Zim, splayed on his stomach, legs spread wide as Dib held both of his wrists behind his back with one hand, the other gripping the side of Zim’s neck and the floor for support. He’d have as vicious a pace as the alien in the video, and Zim would be as chirpy a mess as the other.

Zim’s PAK would be a problem, though. Dib imagined that he’d have taken it off.

The timer ticking, Zim’s PAK making soft clicking noises in warning, Dib thrusting in time with those clicking noises. Zim, a babbling mess, tears spilling onto the floor beneath him as he tried to plead for his PAK’s return despite his uncontrollable pleasured moans.

He let out a gasp as he tipped over the edge, a warm sharp pleasure rising up and overtaking him. He let out a quiet whine, groaning as he leaned over and grabbed the tissue paper he’d left by his monitor.

As he finished cleaning his mess, it hit him all at once, he’d just come at the thought of Zim. Zim. His mortal enemy, the biggest threat to the fucking planet.

A darker chill ran down his spine and he shoved himself away from the computer, throwing himself into bed and covering himself up with the sheets.

He poked his head out to glare at the alarm clock that sat by his bed. 2 am. School was going to be terrible tomorrow, he knew.

How could he face Zim after thinking those things? Zim must’ve done something to him, some sort of hypnosis or something, he deduced.

He decided that tomorrow he would force Zim to tell him the truth, expose him once and for all, and finally be rid of whatever these thoughts were.

His plan didn’t go so well, considering Zim avoided him like the plague.

Dib couldn’t figure out why. Even when Zim had the most nefarious of plots lined up he always told Dib, albeit unintentionally. He was certainly not afraid of Dib, and had no logical reason to be distant and almost cold.

It irked Dib to no end, and he’d been almost ready to explode by the time lunch break was called. Zim leapt out of his seat, taking advantage of the positioning of his seating and running out the door, and Dib let out an enraged growl as the students all crowded the doorway.

He was going to find Zim, no matter what. As soon as the group of students cleared he ran out the doors, avoiding the cafeteria. Zim wouldn’t hide there, too open, too much human food.

As expected, Zim was running across the playground, now also fleeing Keef. Keef cried out, “Zim! Zim where are you going buddy? Where’s Dib? Did you two fight? We can talk about it!”

Dib ignored the twinge of irritation in his chest as he chased after them. Zim spared a glance back and Dib felt a vicious sort of pleasure when he noticed Zim’s green skin pale.

“Zim! I don’t know what you’re doing, but I’m going to stop you!” Zim let out a screech of rage, turning and suddenly shoving Keef backward. Dib yelped as Keef’s body slammed into his own, his arm instinctively wrapping around his waist.

Keef let out a squeak and reddened, flipping around and scrambling off of Dib. “I-I’m sorry, Dib! I didn’t mean to...Zim accidentally shoved me!” Dib rolled his eyes, struggling to ignore the growing lump in Keef pants.

“Yeah, whatever man.” Dib stood, dusting himself off and glaring around the playground. Zim was nowhere to be found. Of course.

He turned to look at Keef for a moment. He was mainly a nuisance, constantly interrupting his and Zim’s fights, butting into their arguments and trying to force the two to hold hands and hug.

This time, however, he could be useful.

“You know, Keef,” Dib began, stepping closer and placing a hand on his shoulder. “Me and Zim had a pretty bad fight. He won’t let me talk to him. If you could find him for me, that’d be great. I just want to apologize and make up. He’s my…best…friend.” He ground out, teeth gnashing together.

Keef’s eyes widened and Dib bit back a groan when he noticed tears pricking at the edges. “Oh, gosh, Dib..I never knew you actually cared this deeply about Zim! It’s almost as much as I do! I’ve got a plan to help get you guys back together again..” He squeaked, and Dib cut in, “Don’t say it like that, that sounds weird.”

“First,” Keef rambled, ignoring Dib’s protest, “We gotta trap him, like a bug..”

[Zim]

Zim panted heavily as he ran through the halls. He had narrowly escaped the Dib’s clutches, with Keef on his tail to boot.

He sighed with relief, slowing to a brisk walk as he glanced around him. Dib wasn’t in sight, and Keef’s pig-like squeals didn’t grate his audial processors–he didn’t have ears, Dib insisted, and demanded he call them something else–so he presumed that they were still entangled on the playground, Dib trying and failing to escape the stalkerish redhead.

Zim looked at the clock. 30 minutes left of lunch. He could do that. He made his way to the cafeteria, grabbing a plate and ignoring the glare from the lunch lady as she grunted, “Next time get to the cafeteria early.”

Zim made his way to a table closest to the bathroom, eyeing the entrance as he pretended to eat. He knew there was another way to enter the cafeteria, but the way from the playground led to that specific entrance, so he remained vigilant, focused only on it.

When Keef burst through, eyes locking immediately on Zim, he leapt up, rushing into the boys’ bathroom and locking the door.

He sighed, putting his hands on his hips and snarling to himself. “That stupid meat child. I can’t-” He froze when he heard the clatter of something wooden behind him.

He whipped around just as Dib lunged forward and cried out when he was slammed against the door. His PAK whirred as he tried to extend his legs, yelping when Dib’s hand slid over it and pressed the compartments' lids shut.

“Zim.” He growled, eyes narrowed and mouth twisted in a disturbing smirk. “Let go of me, let go!” Zim screeched. Dib dragged him away from the door, throwing him to the floor and sitting on top of his lap as he pinned him down, and Zim growled as his PAK was pinned against the floor.

Dib’s smirk suddenly disappeared into a thin line, his eyes shifting, a curious glint flickering beneath the surface. Zim frowned. Dib’s behavior was odd, and he opened his mouth to ask about it.

He froze, question dying in his throat when Dib’s thin fingers wrapped around it. He instantly began kicking his legs, hands reaching up to claw at Dib’s hands and snarling as he attempted to bite at them.

Dib’s other hand reached up and squeezed Zim’s neck tightly as well, his breaths coming out as short puffs of air. “Z-Zim..” He murmured, and Zim’s hips bucked involuntarily at the sharp zip of pleasure that shot up his spine.

He frowned and paused his struggling, confused by his body’s reaction. He took the moment to stare at Dib and fully process what was happening.

Dib was squeezing his neck, yes, but not hard enough to make him feel even slightly dizzy. His face was a bright red, and beads of sweat had formed on his forehead, his glasses fogged from his own and Zim’s breath mixing together in such close proximity.

Zim blinked. Close proximity? With a start he realized that Dib had been slowly leaning down, and his lips were just a few inches away from his own. He growled, snapping his head forward and catching Dib’s lip in his teeth.

Dib squeaked, eyes tearing up as he attempted to pull away. Zim tugged, relishing in the taste of the coppery metal blood dripping into his mouth. “AH!” Dib cried out, his hands crushing Zim’s neck in earnest.

Zim gasped, mouth opening wide and releasing Dib’s lip. He expected a punch to the face, his windpipe to continue being crushed, the fight to escalate.

None of those things happened, however.

Dib’s grip loosened, and Zim flinched when he slammed his lips against his own. Dib’s blood dripped from his lips into Zim’s mouth, dribbling out as Dib all but tried to eat his face.

Zim finally realized his hands were loose and pressed them against Dib’s chest as he told himself to push him, to punch him, pinch, scratch, hurt, hurt, hurt.

But he didn’t.

He gripped the front of it, hips lifting to grind against Dib’s own. Zim wasn’t entirely sure why his body was reacting this way, why he wasn’t destroying him, but he had an inkling as to why.

The dark daydreams he had when he was alone in his lab, when GIR was asleep, when he had nothing but the Dib in his thoughts to accompany him.

He groaned into the kiss, hand sliding up to grip Dib’s hair and pull him away from his mouth. “You’re shit at kissing, Dib.” He snarled, slamming Dib back against his mouth as he led the kiss.

The thrill he felt when Dib moaned and submitted to him, when he began bucking absently into Zim’s hips, was almost unlike any other, comparable only to when he was in the midst of battle in a war.

“Mphn mim..” Dib mumbled into the kiss, gasping sharply when Zim lifted his hips even higher, allowing Dib to grind fully into the space between his leggings. They both gasped at the new friction, and Zim held back a whine.

Dib pulled back, the blood and spit dripping down his chin. “I fucking hate you, Zim.” He snarled, his grinding turning into harsh thrusts as his frown turned to a deep scowl. Zim smirked, the one that always pissed Dib off the most.

‘I hate you too, meat pig.” He snapped, other hand sliding into Dib’s hair to yank his face closer to his own once more. “Now shut up and-”

There was a slam against the door and the boys jumped.

“D-Dib? Zim? Are you two okay? Lunch is almost over, and I think I heard a bit of shouting and grunting..? Please don’t fight! I just want us all to be friends again..” Keef whimpered. Zim frowned, mood ruined as he pushed himself out from under Dib.

He stood up, walking to the door and reaching out to unlock it and let Keef inside. “What we do is none of your business, earth wo- AH!” Zim cried out, Dib having latched onto his shoulder and biting down roughly, slamming him face first into the door.

Zim grit his teeth in an attempt to hold back the moans as Dib licked where he’d bitten him, stepping back and wiping his mouth while staring at Zim with an unreadable expression.

Zim whirled around, glaring as he let his other hand unlock the door. It burst open and Keef, along with an army of other pissed off boys, rushed inside. “God, the fuck were you two freaks doing in here?” A boy muttered as he passed, and Zim ignored the heat that rushed to his cheeks.

“Are you two okay? Are you…friends again?” Keef mumbled, shaking as he glanced back and forth between the two. Zim felt his antennae twitch underneath his wig, a curious glance cast in Dib’s direction.

Dib smiled and placed a hand on Keef’s shoulder. “Yes, we made up just now. Zim was sooo happy.” He mocked, eyes darting over to stare at Zim with that same unreadable look in his eyes. Zim frowned and marched over to the open door.

“Yes, yes whatever. I will be leaving now, I have better earth-worm things to do.” “Wait!” Keef cried, reaching up to gently press his fingers against Zim’s neck.

“What’s this? I-It looks like a-?” Zim stepped backwards smoothly, a fake smile spreading across his face. “Ah, that’s been there. I got attacked by a hobo. I will be taking my leave now.” He curtly spoke, turning and running away as his face flushed at the sound of Dib’s laughter.

He hated him, he hated him so, so, much.

[Dib]

Dib let out a cry as he came for the fourth time in a row. The memory of Zim beneath him, fingers gripping his hair punishingly as he tugged with each thrust, was far too much for him.

Every time he thought he was done, he’d finally been freed from his streak of lust, the memory would flash once more and his dick would rise yet again.

He grabbed his pillow, slamming it against his mouth to let out a muffled scream. He felt himself twitch, cock slowly rising once more. He tossed the pillow aside, gripping the sheets of his bed and glanced at his alarm clock.

3 am. He had to be up and ready for school by 6:30.

He sighed and once more ignored the buzz of his phone. Over the last 2 hours it had gone off multiple times, yet he ignored it. He knew the only person that ever texted him was Zim, and he was the last person he wanted to think about right now.

When the phone rang, however, he scrambled across his bed to grab it, turning off the ringer and glaring at the blurry picture of Zim without his wig on, hunched over and hissing up at him.

He accepted the call, crawling off of his bed and walking over to his computer. As he brought the phone to his ear he leaned over, tapping a couple of keys to bring the security camera feed of Zim’s house that he’d installed last week up and looking around for him.

He frowned when Zim was nowhere in sight, jumping slightly when Zim’s staticky angry growling came from his phone.

“What, Zim.” He snapped. “I told you not to ignore me. I gave you ample warning, so I better not hear any complaining.”

Zim promptly hung up and Dib pulled the phone away to stare at the now darkened screen.

“What-?” He cried out in surprise as the window behind him slammed open, phone slipping from his hands. He whirled around, staring at the small alien hunched on his window frame.

Zim clenched the phone in his hands, throwing it across the room as he launched himself at Dib, grabbing him by the shoulders and forcing him to the bed. Dib struggled against him, yelping when Zim wrapped his hands around his neck and threw him face first onto his sheets.

He grabbed both of Dib’s hands, and Dib felt his blood freeze at the sound of clicking, an uncomfortable pressure tightening around his wrists.

“Zim! Zim what did you-? Ow!” Zim whacked the back of Dib’s head, leaning forward, body flush against his, and snarled in his ear, “This is revenge.”

Dib hated how his erection grew ever harder, biting down on the blankets and willing it to go away. Zim held Dib down by the neck and chuckled. “You made this a little too easy for me, Dib. Where’s your pants?”

Heat flushed his face and Dib could feel the sting in his ears. “Sh-shut up! I was…changing! You interrupted me!” Zim scoffed, and Dib flinched at the sound of Zim’s leggings landing on the plush rug on his bedroom floor.

“When I was watching you through the window I was fairly certain I saw you hunched over your little screens, half bare.” Something wet slid against Dib’s ass and he yelped.

“H-Hey! Asshole, you can’t just-!” The alien appendage began to slide in and Dib bit down onto the sheets, letting out a scream of pain.

Zim, for what it was worth, froze.

“Why are you screaming?” He questioned, tone lilting in offense. Dib let out a quiet groan as Zim shuffled backwards, what he assumed to be the tip of his dick slipping out.

“I get you’re an alien or whatever, but human males aren’t naturally wet in their ass, stupid.” He snapped, writhing against the bonds around his wrists. Zim snorted. “You lie, filthy Dib-thing.”

Dib scoffed. “I’m the human here, Zim! I’m pretty sure I know what I’m talking about.” Zim yanked Dib up by his hair, forcing him to meet his eyes.

“Yes, but you’re also a stupid pig smelly. I, however, did research. I watched the videos. They did not need lube in the videos, because they self lubricate.”

Dib couldn’t tell whether he should be amused by the fact that Zim watched porn, or touched that he even attempted research, presumably for his sake.

“That stuff’s not real, Zim. You always need lube when you do it with guys, even with girls!” Zim frowned, confidence momentarily shattered. “Yes, well…I, the biologically superior Zim, have a solution!”

Dib frowned. “I don’t think I like the sound of th- hghk!?” Dib choked, Zim’s dick continuing to rub almost absentminded circles around his rim.

He was startled at how pleasant it felt, and he went quiet as he relished in the feeling. He frowned when the silence was interrupted by Zim’s panting, which grew ever louder as the seconds passed by.

“O..kay.” Zim ground out, and Dib mourned the good feeling as Zim pulled his hips back. “That should be enough.” He muttered to himself.

A squelch behind him left Dib wrinkling his nose. “What are you doing?” He asked, twisting to attempt to glance behind him. Zim’s hand flew up and slammed Dib’s face into the sheets.

“No! You can’t look. It’ll just be a second you impatient stink monster.” Dib rolled his eyes and relaxed as he felt Zim massage his rim with something hot and wet, and he groaned when the sweet scent hit him.

“Yes, yes, Dib-Monster, I know it feels amazing.” He mocked, and Dib gasped as the sharp and hot pain of Zim sticking both fingers inside stung him.

“God…you know, Zim, they usually do this one finger at a time!” He growled, whining softly when Zim slowly began thrusting his fingers in and out. “Hm. Well, I don’t care.” He murmured, picking up the pace as Dib absentmindedly bucked his hips against him.

“Ah…Zim…” He whined, and Zim suddenly let out a squeak. “Why are you…bleeding?” He mumbled. Dib rolled his eyes. “Probably because you shoved both of your fat ass fingers in at the same time? I just said, they usually do it one at a time to slowly stretch you out.”

Zim huffed. “I’ll take note of that.” Dib sighed as Zim slipped his fingers out, fear sparking in his chest. “Uh, m-maybe..maybe we could just, uh…can we do something else first instead of you putting it..it um, in.” Dib stuttered, yelping when Zim flipped him over.

He blinked warily when Zim’s gloved fingers, covered in slick, yanked his glasses off, and he watched as Zim bent over, genitalia purposefully hidden from view, and yanked his abandoned shorts off of the ground.

He internally wailed as Zim ripped them to shreds, taking the longest piece and covering his eyes with it. “You are not worthy of looking upon Zim’s magnificent body. So, this will have to do.” He snapped, and Dib whined when he felt the writhing appendage from earlier slide against his own.

“H-hah..” Zim gasped, and his hips bucked forward suddenly, absentmindedly, Dib thought. He gasped sharply when Zim’s dick wrapped around his, squeezing tightly.

“F-Fuck, Zim! That..ah..stop squeezing..!” He whimpered, hips bucking upwards into the punishing grip. Zim grunted and pulled back, yet his grip only tightened to the point where Dib let out a shout that was promptly muffled by what felt like Zim’s glove.

“I-I can’t control it! Just…stop moving so much, you’re making me..” He whispered sharply, trailing off as his hand slipped down to gingerly attempt to separate their dicks.

Dib moaned, the feel of latex sliding against him along with Zim’s oddly textured dick becoming too much to bear. “Oh for Irk’s sake can you stop moaning like that? I’ll never be able to get this damn thing to let go of you i-if…you…”

Zim trailed off again, slowly beginning to pant heavily. His hands stopped and he began to thrust against Dib, seemingly giving into the pleasant friction he had created.

“Z-Zim…Zim!” He cried, thrashing once more against the bonds around his wrists. God, he wanted to touch him.

He wanted to feel Zim’s skin under his fingers, to claw and scratch. He chose to instead dig his fingers into his own hand, hissing when he broke skin and blood spilled over his fingernails.

Zim froze, and, despite having no nose, audibly sniffed. “Are you bleeding? I didn’t even put it in.” Dib bit his lip, eyes darting to the side despite not being able to see Zim’s expression in the first place.

“Ah..uh.” He mumbled, shifting a little as he struggled to answer Zim’s question. Their dicks smooshing together served as quite the distraction, after all.

“I just…accidentally, uh…Zim, can we focus on-?” Dib flinched, shocked, when Zim’s wet tongue lapped across his lips. “I like it.” Zim snarled, hands sliding onto Dib’s shoulders and gripping them roughly.

“I like the smell of your blood while we do this.” He whispered, body flush against Dib’s and grinding. He held in a cry as Zim bit his neck, continuing his grinding.

He lifted his legs, wrapping them around Zim’s hips and whimpering when he felt his sharp teeth sink into his skin.

“Y-You idiot! That’s gonna leave a fucking m-mark..!” He wailed, annoyed when Zim’s left hand slid up to cover his mouth. He let himself be flooded with the pleasure, sinking deeper and deeper into it.

He ignored the drool that spilled from his mouth, the pathetic pleads that spilled out, begging for more, more, more, and he tried to ignore how good it felt to be marked by Zim, to hear him whispering his name in his ear.

Zim continued to squeeze and slide his tentacle like dick up and down, occasionally slipping his tip against the slit of Dib’s. The two continued their frotting until they finally grew near, and Zim bent over, viciously biting onto Dib’s neck and sucking as hard as he could as he came.

Dib couldn’t hold back the muffled hoarse scream of pain and pleasure that slipped past his lips as he came, groaning at the feeling of their cum mixing together on their abdomens.

Zim let go of Dib’s neck with a pop, a quiet chuckle escaping his lips. “You’re loud.” He mumbled, attempting to pull away and sighing when his dick refused.

“Well, we're stuck.” “S-stuck? What do you mean?” Dib yelped, trying to worm away from Zim’s grasp and groaning as he was squeezed tighter, embarrassed as his cock spurted a little more from the sensation.

“You don’t listen, Dib.” He snarled, flopping on top of him and panting in his ear. “We’re stuck. I can’t…make it stop. Just wait a while, it usually goes away on its own.”

Dib held in a frustrated scream. “What do you mean, a while!? We have school tomorrow, it’s-!” He paused, biting his lip as he asked, "uh..what time is it?" Zim shifted a bit on top of him. "4:30 in the morning." He smoothly replied. Dib groaned in horror as he continued his previous thoughts, “It’s 4:30...4:30 in the morning, you idiot! Why did you…? Ugh!” he sighed, tense body relaxing.

“Will you at least take this damn blindfold off?” “No.” Zim promptly squeaked in amusement, grumbling when Dib tried and failed to slam his shoulder against him.

“Fuck you, Zim.” He snapped. “Yes, yes, you already tried.” Zim quipped. Dib felt his dick perk up at the memory of what happened in the bathroom. “Shut up..”

Zim felt it too.

“Hmm..you know, I could go one more time..” He murmured, hips bucking slowly and cock winding around Dib’s even tighter. “N-no! It’ll probably take even longer to-!”

Zim pressed a gloved finger to Dib’s lips, and Dib hated how he obediently went silent. “We’re gonna be stuck here either way.” Zim offered, and Dib frowned, mindlessly grinding against Zim as the grip on his dick tightened even more.

“Y..yeah, I guess.” Dib huffed, giving into the pleasant sensation below. “But just once, okay? Then you better figure out how to make that thing let g-!” Dib cut off with a hiss as Zim began to roughly grind into him.

“Stupid Dib-Thing. I like you better when you’re whimpering. Now shut up.” Dib hated what that did to him, stomach flipping and twisting in knots.

Zim began thrusting faster, squeezing tighter, and Dib realized that despite what he’d said, they wouldn’t only be doing this once more.

[Zim]

Zim was irritated. Dib hadn’t shown up to Skool today. He hadn’t texted warning him about his absence either. Now he was left with Keef’s bothersome presence.

Ever since he’d arrived the little red-head had been obsessed with him, touching and talking and existing annoyingly. Today, however, he was even more annoying. Dib’s absence seemed to inspire a boldness in him unlike anything Zim had seen before.

His hand lingered on the small of Zim’s back, he whispered close enough to his face that Zim swore he could feel the ghost of his lips against his cheek, and it all made him feel disgusted and angry.

He thought back to the times he and Dib had kissed, and frowned. Naturally, as his enemy, Dib was a disgusting creature to Zim. Yet, if he had to choose between Dib and Keef, he’d pick Dib.

He thought a bit more about it. Between Dib and any wretched creature in the entire multiverse, he’d probably pick Dib.

He nodded to himself, concluding that it was natural for enemies to prefer the familiarity of the other. After all, there couldn’t be anything more to these feelings. That’d be wrong.

So when Keef led Zim away from everyone to a secluded part of the recess field, pushing him up against a tree and trying to kiss him, Zim had no qualms about shoving him away.

“What are you doing?” He snapped. Keef frowned, looking like a kicked puppy. “I-I just wanted to kiss you, Zim…I really like you, and I want to be with you.” Zim snorted, rolling his eyes as he pushed himself off of the tree, walking away.

“Yeah, no. I don’t like you, Keef, and we will never be together.” “B-but! Why, Zim!? Why! Is it because I'm not Dib? I can be like Dib!” Keef cried, and Zim froze, whirling around with a snarl on his face.

“Shut up, Keef. I don’t like you, and I don’t like Dib. I don’t like anyone! Now back off!” He shouted, turning and stomping his way back to the Skool, blood rushing into his face and leaving him feeling as if he was boiling alive.

He did not like Dib. He liked the way Dib could make him feel good, yes. But like him? In the way the human pigs did, with the hand holding and the kissing without the sex?

There was no way. He would never do any of that with Dib, not in a million years. Yet he couldn’t help but imagine it.

What would a human date with the Dib even be like? There would be hand holding, it's practically a rite of passage for the stink pigs. Zim had once held Dib’s hands in his own, when he had tried shoving him away and Dib had grabbed his hands.

The two began a match of brute strength, trying to shove the other’s arms back and slam them into a wall, but had ended up locked, hands gripping each other tightly, for several awkward minutes.

Eventually Zim had allowed himself to be beaten, and he couldn’t ignore the zip of pleasure that came from his nether regions and traveled up his spine at the memory of Dib slamming him back against the wall, snarling where his audial processors were.

Zim struggled to ignore the way his dick attempted to unfurl in his leggings, rushing inside the Skool and heading for the rarely used boys bathroom, right next to the abandoned music room.

He ran into a stall, slamming the door shut and sitting on a toilet seat, sliding his leggings down and groaning as he watched his pink tendril slip from his folds and rise.

He gingerly wrapped his hands around it, whimpering at the feel of the latex against the ridges. “D-Dib..” He whispered, slowly tugging as he squeezed his eyes shut and let his mind wander.

During the date with the Dib they would have to hold hands. Dib’s palms would be sweaty, just like they were when they had fought. They would probably have to kiss too.

Zim imagined how the kiss would go. Dib would make the first move, his sweaty hands gripping Zim’s pristine and clean superior ones tightly. Zim would roll his eyes as Dib squeezed his eyes shut, slowly and shakily leaning in closer and closer.

It wouldn’t be their first kiss, like in the movies, but that wouldn’t matter to a chronically anxious idiot like the Dib. Zim would have to put in the work, lean forward and slam his lips against Dib’s.

His hands picked up the pace and he sighed loudly.

Dib would yelp, his hands would instantly fly up to grip Zim’s antennae and his shoulder, prepared to attack if Zim tried to eat his face. Zim would not, though. Not like that. He would dazzle Dib with his kissing skills.

He let out an airy chuckle at the thought. Dib would be dumbfounded, a twitching blushing mess once Zim was done with him. He had learned even more from the human videos, and he was excited to use them.

Dib would buck his hips against Zim’s, chasing an even deeper pleasure because of Zim’s seductive kissing abilities.

Zim sped up his tugging until he couldn’t go any faster, moans freely spilling from his mouth.

“D-Dib…Dib..!”

Dib would allow Zim to pin him on his back, and Zim would reveal his genitalia to him. Dib would be in such awe he would feel shame at his inferior mating organ, attempting to cover it with his hands.

Zim snarled at the thought, chasing the orgasm that was rising within him.

“Dib.”

Zim would yank apart his legs, grabbing his hands and pinning them above him. He would slide in between Dib’s beautiful thighs, slicing them to mark him as his, Zim’s, and kiss Dib deeply.

He felt something coiling tighter and knew he would come undone with one more push.

Dib would cry out, and his hips would rise to meet Zim’s own, and once he was fully hilted in Dib, Dib would slip his hands out from Zim’s grip, slide them up Zim’s chest and around his neck as he pulled himself upward and closer to Zim’s lips and whisper,

“I love you, Zim.”

Zim’s eyes flew open as he came, chirps and squeaks escaping his lips as he experienced one of his best orgasms yet. He panted heavily as the high dragged on, slumping to the side as he fought to catch his breath.

He blinked wearily, vision clearing as he realized the stall door was wide open. He frowned, wiping himself up quickly with toilet paper before standing and peeking out. There was no one there.

He would surely have noticed someone walking in, wouldn’t he? He realized that his eyes had been squeezed shut, his own pathetic whimpers and moans had filled his ears, and that Keef had been chasing after him moments before he’d run to the bathroom.

Horror, cold as ice spilled down his back and he leapt up, yanking his leggings back over his hips and tugging his dress length uniform top down, running out of the bathroom and towards his next class.

Infuriatingly, Dib was absent again. Keef was also mysteriously missing, which only made Zim’s suspicions worse.

If Keef had seen what he’d done, would he tell people? Did he hear how he had called out to Dib? Would he tell Dib? How would Dib react?

The two had already done things together, so his reaction couldn’t be too bad. Zim thanked the Tallest that his thoughts were his own, refusing to acknowledge the weight of what he’d daydreamed about truly meant.

The class goes by quickly and Zim rushes out, heading straight for Dib’s house. The anxiety of the day and the fear of Keef getting to him first led to him carelessly using his PAK legs to speed towards the Membrane household, scaling the brick wall and flinging himself through the open window.

He landed with a thud, glancing around the dark room. “Z..Zim..?” Dib croaked, and Zim turned and lifted his head to look up at him. Dib was wrapped in blankets, shivering intensely.

His face was a bright red and the room smelt like human sickness. Dib’s glasses were abandoned on the little holder he’d built into the wall beside his bed, and he sniffled and wiped at the snot dripping from his nose.

Zim frowned, disgusted and concerned. “Why are you like this, you stinky pig? I didn't even bring the animals with fur around you.”

Dib rolled his eyes. “It’s not an allergic reaction, stupid.” He sniffed, reaching for his glasses and shoving them on his face as he glared down at him. “I just have a cold. Why are you here?”

“Why didn’t you text me!” Zim shouted, pointing an accusatory finger at Dib’s face. “I was left alone with that disgusting Keef all day. He even dared to attempt to kiss me, and spoke all this nonsense about liking me and-”

Dib held a hand up before crawling off his bed, dragging the sheets down with him and covering Zim with them as well. “Okay, now let’s talk.” He rasped. “What happened?”

Zim couldn’t help that his pulse began to beat faster. He decided it was because Dib had trapped him in a blanket of sickness. “That…Keef-Monster tried to kiss me! He told me he liked me, and all of these weird things that don’t make sense. He wanted to be with me, in that gross and disgusting human way in the movies.”

Zim paused, gauging Dib’s reaction. It was dark under the blanket, but he didn’t miss how his eyes sharpened. “And it’s your fault!” He screeched, hands surging forward to shove Dib, stopping only when he remembered he was sick.

“You are lucky I do not want your human meat germs, or else I'd have killed you by now.” He huffed, ignoring the way Dib chuckled.

“Well? Do you like Keef?” Zim stuck his tongue out. “No way! I wouldn’t ever want to do that stuff with Keef..the hand holding, the kissing, the mating, it is all disgusting.” Dib’s brow cocked at that, but whatever he’d thought remained unspoken.

“You must apologize to Zim, or pay the consequence for leaving me alone with that vulture!” Dib rolled his eyes, scooting backward a little. “I am not doing that. I don’t have to tell you when I’m sick, or when I’m not gonna be at Skool. What, do you think you’re my boyfriend or something?” He teased, and Zim felt heat rush to his cheeks.

The words stung, but he wasn’t sure why. Dib wasn’t his boyfriend, that was a fact, and Zim didn’t care for the labels of boyfriend and girlfriend and the like anyway.

Yet it still hurt.

“No! Anything that ends with “friend” we are not!” He screamed, lunging forward and slamming a hand against Dib’s neck as he used the other reach for Dib’s star covered blue pajama pants.

“W-Woah! No, wait-!” Dib croaked, hands reaching to grab Zim’s hand and pull it away. Zim paused, glaring up at Dib.

“Apologize.” He snarled, but he wasn’t sure what he wanted Dib to say sorry for anymore. Dib, ever the prideful idiot, shook his head, scowling. “N-no..!” He choked, hands clawing at Zim’s face.

Zim hissed when he felt one of Dib’s nails slice his skin, and he shoved his hand down the front of Dib’s pants and squeezed his dick as hard as he could. Dib whimpered and his own hands slid down, reaching into Zim’s leggings.

Zim yelped in surprise, attempting to shift so Dib couldn’t slip his hand in. It was useless, however, and Dib’s surprisingly soft hands rubbed against Zim’s folds frantically.

Zim clutched Dib’s neck even tighter, grunting when one of Dib’s hands slipped from Zim’s pants and wrapped around his throat and squeezed as well. He hated how good it felt, to be choked and teased as he did the same for him.

“Let…g-go…” Dib groaned, hips bucking into Zim’s hands. Zim ground his hips against Dib’s fingers, whining when they finally slipped inside and began to press along his walls.

“On-only..if you do…first..!” He gasped, knowing that would never happen. The tension only grew as Zim stared into Dib’s eyes and he thought of the daydream from the bathroom again.

He wanted to kiss Dib. He began leaning forward, and Dib, the stupid boy, took it as a sign of victory. His eyes twinkled with delight and the speed of his hand picked up, which only made Zim’ tug faster.

Zim gently pressed his lips to Dib’s, shutting his eyes and relishing in the feel of Dib’s dry and cracked lips on his own.

Dib froze, all parts of his body stilling, his grip on Zim’s neck loosening. Zim followed suit, allowing his hand to slide up from Dib’s neck to the side of his face as he tried to deepen the kiss.

Dib allowed it, and Zim felt something warm burst in his chest. He growled when Dib fought back against him, attempting to take the lead.

He scratched the side of Dib’s cheek, earning him a yelp, and began to lead the kiss. Dib whined, hands slipping and sliding all over the side of Zim’s body, and Zim let out an airy laugh at how it tickled.

Dib lifted Zim up slightly, setting him on his lap and rubbing his thumbs in circles over Zim’s protruding hip bones. After several minutes the two pulled apart, gasping for breath.

Zim stared at Dib’s face, processing what had just happened. Dib stared right back, his already flushed face an even brighter red, and his hair was messy from where Zim’s hands had slipped into it and tugged.

Zim’s chest heaved in time with Dib’s and he jolted when he realized that he had just made out with the very much sick Dib. “AGH!?” He cried, scrambling backwards and out of the blanket, rushing towards the window and flinging himself out of it.

He ran the whole way home, horrified, and burst through the front door. GIR, who had been laying on the couch, leapt up, saluting Zim before bursting into a fit of giggles and returning to watching his tv show.

Zim immediately went to the lab to perform tests upon himself and check to see if he had been infected. After he had performed numerous checks and deemed himself healthy, he sulked on the floor.

He hadn’t planned to please Dib, he was supposed to make him suffer. Ever since that horrible day in the bathroom Zim had become soft, distracted, misguided. He couldn’t allow himself to continue like this anymore.

He clenched his fist, strengthening his resolve. From today onward, he wouldn’t do anything with Dib. He would only fight him and treat him as his enemy, like a proper invader would.

He wouldn’t daydream about the dating, or the mating, or the hand holding and kissing. He would go back to the way things were supposed to be. No matter what.

[Dib]

Dib stared after Zim as he left, blinking in confusion. Zim had burst in screaming about how much he hated kissing and the like, then made out passionately with him for several minutes before disappearing.

He was hypocritical in all things, it seemed. Dib stood, taking his blankets with him as he curled up in his bed, willing his erection to go away.

He was too tired to take care of it himself, and he only wanted Zim’s hands around it anyway. He closed his eyes and let his mind wander.

He thought of Keef asking Zim out, and how Zim might have reacted. He imagined Keef leaning closer to Zim’s lips, Zim blushing and leaning back, their lips connecting, and Dib slammed his hand against his wall to end the horrible thoughts.

He didn’t like the idea of Keef and Zim. Thankfully, Zim had rejected Keef, so he had nothing to worry about. That’s what he tried to tell himself, anyway.

He knew he wouldn’t get the anxious and angry thought out of his mind until he saw it happen with his own eyes, so he resolved to be better by the morning and go to Skool, no matter what.

He took his glasses off, snuggling under the blankets and slept until the morning. When his alarm went off he groaned, his body still felt sluggish and hot. He knew he was going to Skool despite this, and he dressed himself, stumbling down the stairs and out the door.

Gaz walked beside him, watching him from the corner of her eye. “You’re still sick, Dib.” She spat, stepping away from Dib to walk further apart.

Dib sniffed, rubbing his nose. “Yeah, well it’s not that bad. Besides, saviors of the world don’t take sick days!” He shouted, laughing maniacally as he ran the rest of the distance to Skool, rushing up the steps, through the doors, and into his first class.

He frowned, apprehensive when he realized Zim wasn’t in his seat. He was very punctual when it came to Skool, thinking it made him appear more normal to walk in at the exact same time every day–7:45, Dib had memorized it–when in reality it made him look even more inhumane.

He stalked towards his seat, slumping into it and glaring out the window at the field. He was surprised to see Zim out by the tables, Keef standing next to him.

They appeared to be talking, Zim’s arms were flailing and Keef was fidgeting, stepping closer and closer while Zim ranted. Dib frowned, the sick heat from his chest rushing to his head, leaving it pounding.

He stood, opening the window and straining to listen to their conversation. He heard bits and pieces, something about himself and a bathroom. He sighed, crawling out of the window and ignoring Ms. Bitter’s screams as he ran in their direction.

He slowed to a stroll, eyeing a nearby tree. He slipped behind it, peeking around the corner. The two were still a distance away, but he could make out what Zim was shouting clearly now.

“I can’t believe you fucking watched me, you disgusting…disgusting slimy pig!” “I didn’t….accident..!” Keef softly spoke, and Dib strained to catch part of what he was saying.

“You’re gross, Keef, you’re horrible!” Zim screamed, hands flying up into his wig and clenching fistfuls of hair.

Dib knew what that meant. Zim wanted desperately to grab his antennae and tug, it was a comfort thing for him. Dib also knew that with antennae yanking usually came stomping.

As he expected, Zim began to pound his boots into the ground, letting out clicks and deep chirps. He had to be losing it if he was allowing himself to spew irken and make his alien noises in front of a human.

Dib decided enough was enough and stepped out from behind the tree to intervene. He paused when Keef pulled out his phone. “I took a video, Zim.” Keef said, voice flat and devoid of emotion.

Zim looked stricken, hands immediately falling to his sides and his feet planting into the ground. He stared with a look of horror at the phone, glancing between it and Keef.

“Y-You…you fucking what!?” He shouted, lunging forward to swipe at it. Keef stepped back, grabbed Zim’s arm and yanked it down to pull him close to his face.

He whispered something to Zim, and Dib watched as Zim paled. He had enough, marching over and pulling Keef away with such force that Keef let out a cry of pain.

“Hey, I don’t know what you’re doing, man, but leave Zim alone.” He spoke, standing in front of Zim to shield him from Keef’s sight. Keef’s eyes widened at the sight of Dib, and he smiled.

“Oh, of course. Well, Zim, just think about what I said. I would hate for us all to stop being friends.” Keef turned and walked back towards the Skool, and Dib turned around in time for Zim’s fist to connect with the side of his face.

He cried out, clutching his already swelling cheek and glaring up at Zim as a tear welled up in his eye. “Geez, what the hell, Zim!? Why did you do that?”

Zim stared down at Dib with that same horrified look, his mouth a thin line and his hands shaking. “Stay away from me, meat monster.” He snarled, turning and running after Keef towards the Skool.

Dib was bewildered. Zim chose to go with Keef over him? After what he’d just seen? It had looked like Keef was harassing him, and yet he had chosen his company over Dib’s.

The red hot embarrassment and anger he felt as Zim slowed to stride alongside Keef was too much, and he sank to the ground to hold his head as the pounding began.

He was too sick to deal with whatever the hell was going on, and he dragged himself to his feet, and began the walk home. After arriving home, taking medicine and laying around for a while he finally felt good enough to head downstairs.

He found his Dad in the living room, sitting and watching a few reruns of his TV show. “You know, son.” He said, despite not turning to look at him.

“I do believe that one friend of yours has been stopping by quite a bit. You don’t need to sneak him in. You can just ask to have a sleepover.” Dib blushed, silently praying his Dad hadn’t ever heard what the two got up to when they were alone.

“Uh, yeah. Actually, I think I wanna have a sleepover tomorrow, Dad, would that be okay?” Membrane practically leapt up off the couch, turning to look at Dib with excitement.

“Of course! I’ll be home that day, I’ll even cook dinner for us!” He shouted, rushing into the kitchen and pulling out multiple cooking books. Foodio sped to his side and the two began conversing about what a proper meal for multiple people would be like.

Dib pulled out his phone, sending Zim a text asking him to come over tomorrow night. Dib was surprised to see the little white bubble pop up immediately, signaling that Zim was typing. He rolled his eyes at the response he got.

“No”. Dib shot back, “Already told my Dad ur coming so if u dont u’ll look stupid” No response for a while. Dib almost gave up, turning his phone off and putting it in his pocket when it buzzed. “Fine”.

He smiled and raced up to his room, plotting various ways to torture Zim throughout the night. Eventually he drifted off, sleep catching up to him.

He awoke to the feeling of something heavy on his chest.

He blinked, surprised to see Zim on top of him. He opened his mouth to speak, only to choke as fabric slipped further into his mouth.

He realized that Zim had tied him to his bed and gagged him, and now Zim was crawling up his body, settling firmly in the middle of his chest.

Dib tried his best to question Zim with his eyes, but Zim reached beside Dib’s head and pulled back, now holding a blindfold, and Dib knew he was screwed.

He thrashed, trying to ignore how the blood that had rushed to his head upon waking up in such a position was steadily making its way downward.

Zim fixed the fabric around Dib’s eyes and Dib groaned, going limp and accepting his fate. He wished that Zim would let him lead again, the memory of the boys bathroom incident clear in his mind.

Zim scooted back, grinding his ass against Dib’s crotch and letting out a pleased chirp when Dib whimpered. Dib thrusted upward, viciously wanting nothing more than to ruin whatever Zim had planned for him.

He wouldn’t go along with it, not after his stunt on the playground. Zim disregarded this, grinding into each thrust and letting out the first chirp Dib had ever heard while they were doing this.

He had always wondered why Zim never made any noises, he was alien after all and he couldn’t hold his chirps and clicks back when he was angry, so why could he when they were touching one another?

He wanted more. He thrusted upward faster, groaning at the pain and pleasure of his clothed dick rubbing against Zim’s leggings.

Zim let out more chirps, hands sliding up his chest and squeezing his neck gently. Dib instantly remembered the incident under his blanket and he moaned, allowing himself to become putty in Zim’s hands.

Zim made a noise that sounded like a strangled laugh. “There we go, Dib.” He spoke, patting his head gently a few times. He slid his hands downward, tugging his pajama pants down along with his boxers and admired his cock for a moment.

Dib blushed with embarrassment as Zim nosed at it, making little sniffing sounds as he poked and prodded. If his mouth wasn’t gagged he’d have probably told Zim to hurry up already, yet he seemed to get the hint despite this and Dib flinched when he felt Zim’s tongue slide along the slit of his tip.

He bit down on his gag, refusing to let out any more pathetic sounds. He knew that was what Zim wanted. Zim merely continued lapping at the head, his fingers sliding up and down the base absentmindedly, sometimes pausing to murmur what Dib hoped was praise in irken.

Zim finally took the tip in his mouth, swirling his tongue around it in circles. The sensation was odd and new to Dib, and he couldn’t help the whine that slipped past his clenched teeth.

He could feel Zim smile around him as he sank further down, taking in more and more of him, tongue winding round and round his dick until his lips pressed against the skin surrounding it.

Dib’s mouth had dropped open, the feeling so foreign it had taken all of his willpower not to cum just from the small act alone. The gag had managed to stay stuck in between his teeth, however.

When Zim began to suck, tongue sliding up and down his shaft, he knew he was lost, and he bucked into his mouth, babbling muffled utter nonsense and pleading like a fool through the bundle of fabric in his mouth.

He didn’t know what he was trying to say, only knew that it was too good and that he couldn’t stand it and he needed Zim to keep going, to keep doing more, more, more until he couldn’t even think straight.

He came with a hiss, heart sinking as he realized the pleasure would have to end. Zim pulled away with a pop, and Dib wrinkled his nose as he realized he’d cum directly into Zim’s mouth.

He blushed as he imagined it dripping from his lips, Zim clasping both hands over them in an attempt to hold it in. Zim clicked his tongue and began lazily pumping Dib with his hand.

“Still hard, stink pig?” He spat, annoyance dripping from his words. Dib shook his head, pleading internally for Zim to stop, to let him have reprieve, yet his tugging only increased in pace as a response.

A claw yanked the fabric out of Dib’s mouth and he gasped, instantly babbling for Zim to stop, slow down, give him a second to recover before continuing. Zim only continued ever faster, free hand slipping up into Dib’s nightshirt to play with one of his nipples.

This sent Dib into a panic as he felt himself begin hardening up again, and he twisted to where Zim’s fingers couldn’t reach. The alien growled and forced Dib to lay flat on his back, continuing to squeeze, pinch, and tug at his nipple while he jerked him off.

Dib moaned loudly, giving into the pleasure and bucking his hips once more, legs thrashing as he tried to ignore the overwhelming feeling of the sensations.

Dib knew he was growing close again already and he begged for Zim to take the blindfold off, to allow him to look at him. “What do you call me?” Zim snarled, his voice whiny and airy.

“Z-Zim, I don’t want to play your stupid-!” Zim suddenly froze, no longer moving or giving Dib any stimulation. “You should know your place, Dib. What do you call me?” He asked again, and Dib sulked as he mumbled, “M-Master?”

Zim was silent for a while before he violently yanked the piece of fabric off, his ruby eyes boring into Dib's amber ones. “Good little human boy.” Zim whispered, beginning to pinch and yank once more.

Dib blushed at the intensity of Zim’s gaze and the way his eyes were fixed upon his own. For a moment he wished the blindfold was still on so he wouldn’t have to face the look on Zim’s face.

He glanced down to watch gloved fingers slide against him and took it back, whimpering as he grew ever closer. Zim lifted up Dib’s night shirt and leaned forward, mouth suctioning around his nipple and sucking as hard as he could.

Dib’s hips flew up into the air as he came, a strangled cry escaping his lips as he tried to hold himself back from thrashing around too much. Zim continued sucking even as Dib released, and eventually Dib began to beg for him to stop.

“I-it’s too much, Zim! I can’t…please…” He groaned, wishing for nothing more than the ability to run away and hide from Zim’s streak of lust. Zim carried on sucking, however, and his hand slowly began to pump his drained and abused cock once more.

Dib felt tears spring to his eyes as he glared down at Zim, who only smirked up at him, eyes twinkling with amusement. He pulled away from Dib’s chest with a gasp.

“I wanna see how many rounds a human can go before being entirely incapable of carrying on. You are too sick to come to Skool, and I chose to skip today. So why don’t we find out, hm?” Zim whispered, his long, snake-like tongue slipping out to teasingly lick Dib’s ear.

Dib grunted and nodded, desperate for more from him. He didn’t want this to end. He’d willingly be Zim’s experiment, for as long as he needed him.

Despite this, he suddenly felt his eyes drooping, sleep rushing to overtake him. He whined and tried to fight it off, but ever so slowly his eyelids lowered, and he slipped into the dark.

He jolted upright, glancing around his room. He glanced downward, noticing the dark wet spot on his blanket and sighed. Of course he had a wet dream about Zim.

He sighed and ran a finger through his hair, glaring at his window and plotting to get his revenge on Zim at their sleepover tonight.

Chapter Text

[Zim]

It was Saturday, the worst day of the week. On Sundays the pig smellies were all at their churches or in their houses minding their own business, but Saturdays seemed to be the day everyone was out, almost always.

Despite this, Zim dragged himself from his base, telling his computer to prevent GIR from destroying his things too much, and headed for the Membrane household.

If only the stupid pig smelly Dib-Father hadn’t heard Zim was coming, he’d have stayed home. The wig stuck to his forehead, slick with his sweat, and Zim swatted at the flies that began to buzz around him.

The straps on his backpack, gifted to (or rather, thrown at) him by Gaz, weighed heavily on his shoulders. He’d only been outside 5 minutes and he already felt a good cleaning chalk scrub was needed.

Once he arrived at their door he simply walked inside. They rarely ever locked the door—mostly due to their high tech security system outside—and Zim took advantage of that to the fullest.

Membrane had, for some foolish reason, programmed the security systems to recognize Zim and allow him through, but Zim had no complaints.

It was all the better for him to have easy access to his mortal enemy’s base. He headed through the living room towards the stairs, antennae attempting to flick up under his wig.

He didn’t hear the sounds of Gaz gaming, or Membrane tinkering with something highly explosive downstairs in his labs. Zim slowly approached the all too familiar door of Dib’s room and he reached for the knob.

It swung open before he could grasp it, and a hand pulled him inside. The door slammed shut as Dib pinned Zim against it, earning him a yelp.

Zim looked up at Dib’s eyes, blinking in confusion at how crazed and angry they looked. “Zim.” He said, voice lilting with a twisted glee.

“Ah, ah, ah!” Zim spat, slipping out of Dib’s grasp. He tossed his backpack to the side of Dib’s bed, marching over to it as he widened the gap between them. “Zim has had enough of entertaining you, pig smelly!”

Dib blinked, obviously confused. His massive eyes had dark circles underneath them, and Zim deduced he’d stayed up late stalking him again.

“Let me spell it out clearer for your inferior sleep deprived brain. No more of the touching, or the- the kissing, and…stuff.” He finished lamely, arms that had raised mid sentence dropping to his sides.

Dib’s brow quirked at that, and he gave a disapproving frown. “Why not?” He asked.

Zim wasn’t expecting such a blunt and straightforward question, and he stammered as he spoke, “We are enemies, Dib. Enemies do not mate.”

Dib’s frown deepened, bordering on a scowl. “So? Who cares. I still hate you, and you still hate me. The “mating” is just a benefit.” He grumbled, crossing his arms as he leaned back against the door.

Zim snarled, hands balling into fists at his sides. “I said no!” He snapped, and Dib straightened with a start, eyes widening.

“Yeah, I get it, Zim. I wasn’t gonna force you or anything. I was just…whatever.” He mumbled, turning and opening his bedroom door.

“Dad and Gaz went out to go get pizza. He tried cooking for you, and…well…” Dib’s arm raised in the air before falling to his side as he grasped for the right words to say.

“Let’s just say Foodio is out of commission for a while.” He snickered, walking out of his bedroom. Zim followed, rushing to catch up as Dib headed down the stairs.

His phone, which he’d long forgotten, buzzed against his hip. He lifted his dress to grab the phone from out of his stockings, eyes narrowing when he caught Dib staring at the sliver of skin.

“Pervert Dib.” He snapped, rushing ahead of him into the kitchen. He ignored the way Dib sputtered and attempted to deny his leering, instead reading the text on his screen.

“Go to the bathroom, Zim”. Zim shifted from foot to foot, holding in a groan as he glanced back to where Dib was in the living room, setting up the Game Slave console.

He was entirely focused on it, and Zim took full advantage as he slipped into the guest bathroom beside the kitchen.

He locked the door behind him, walking over to the toilet, shutting the lid and sitting atop of it as he checked his messages. 10 missed.

All of them consisted of Keef demanding he hurry up, sending still images of the blurry video he’d taken of Zim in the bathroom stall as warnings. “I'm here.” Zim texted back, glancing up at the door every few seconds.

“I don’t have a lot of time, I'm busy.” Zim waited patiently for Keef’s reply, groaning when it arrived and he read its contents. “Why? Who are u with? Is it Dib?”

Zim thought about lying, but decided against it. “Yes.” Zim waited patiently for Keef to reply. “Ask him if i can come.” Zim blinked. “What?” He texted back.

Keef didn’t reply, and Zim sighed as he made his way to the bathroom door. He opened it, yelping in surprise when he realized Dib was standing right in front of him, arms crossed, scowling.

“What did you do to my bathroom, Zim?” He questioned, peering around and opening the sink doors, pulling back the shower curtain and lifting up the toilet seat in his quest to find something tampered with.

“I did nothing, Dib!” Zim snapped. “On to more important things, Keef wants to stay over too.” There was a brief pause. “What.” Dib asked, back still turned on Zim.

Something about the tone of his voice and the way he didn’t turn to make eye contact made Zim’s throat dry up instantly.

“I…I’ll go home if you don’t let him. He won’t stop bugging me all night if you don’t, so unless you want to hear constant buzzing and ringing, you should at least let him come over for a while.” He stammered out, anxiously glancing back at the open door.

He could make a run for it right now in case Dib chose to attack. Upon realizing how cowardly a thought he had, he grew angry. Zim wasn’t scared of this big headed brat.

He puffed his chest out, clenching his fists at his sides as Dib slowly turned. His face was eerily blank, the only expression a small smile on his face as he spoke, “Sure, Zim.”

He brushed past him, heading towards the living room. Zim frowned, eyes narrowing. He followed Dib, walking beside him as they reached the couch.

“Let’s play some games while we wait for Keef to get here.” Dib mumbled, grabbing a controller and flopping onto the couch.

Zim quickly typed a message to Keef telling him he could stay over for a few hours before shutting his phone off, leaping onto the couch and settling down beside Dib.

He grabbed a noticeably new green controller and squinted at the tv. “What are we playing?” He asked. “Rise of the Pigs.” Dib answered.

Zim furrowed his nonexistent brow. “Rise of…what?” Dib chuckled. “It’s a new game that was 5 dollars. It’s probably nothing good. But it’s multiplayer, so, works out.”

Zim huffed as they entered the character selection and Dib chose the pig with a green shirt. “Excuse me?” He shouted. “I deserve the green pig!” He made a swipe for Dib’s controller, growling when it was lifted out of his reach.

“Why? Cause you’re an alien?” “No! Because, uh…I said so!” Zim snapped, crawling on top of Dib and reaching for the controller.

Dib shoved his hand against Zim’s cheek, pushing him back as his short arms scratched and clawed at his arm.

“Ow! Stop it, Zim, it’s mine! I let you have the green controller, why can’t you just– ACK!” Dib let out a squawk as Zim bit down on his hand, scooting further up his chest and snatching the controller from him.

Dib pulled his bitten fist backwards, preparing to punch Zim when the front door suddenly flung open. “Hi, guys!” Keef squealed, pausing when he saw the compromising position the two were in.

“Are you guys wrestling?” He asked, casually strolling over to the couch and crawling behind Zim, laying his stomach on Zim’s back, legs on either side of Dib’s chest.

Zim shivered with disgust, wishing for nothing more than to use his PAK legs to murder Keef there and then. The blood would get on Dib’s stinky couch, however, and he felt too merciful today to leave a mess.

Zim shook Keef off of him, grinning with a vicious pleasure at the sound of Keef hitting the ground. He finally looked back to Dib, startled once again by the blank expression on his face.

“Are-?” Zim began, but as he began, Dib lunged forward, grabbing the hand that held the controller Zim had stolen and shoving him on his back on the couch, pinning him in turn.

“That’s mine, Zim.” He said flatly, snatching it before leaning back and sitting on his side of the couch, motioning for Keef to grab one of the controllers on the floor.

Zim felt rage flare in his chest, his cheeks warming with embarrassment. Dib had humiliated him in front of Keef, and Zim was going to make him pay for it.

He sat up, scooting beside Dib and snatching his abandoned controller, and grumbled as he chose the pig wearing a purple shirt. “Gaz is gonna be mad at you.” Dib muttered.

“Gaz isn’t here right now, is she?” Zim shot back, shrinking away when Keef sat in the middle of the two, shoving his way between them and settling into Zim’s side.

He chose the pig with a red shirt. “What kind of game is this, guys? Huh?” Zim bit his lip, refusing to answer him. Dib let out a low groan as he explained what Rise of the Pigs was once again.

Keef nodded, yet Zim had an inkling that he wasn’t paying much attention to what Dib was saying, considering his hand had drifted over to Zim’s leg. Zim ignored it, focusing on accessorizing his pig.

A black coat. Big goggles. Blue shoes. His pig was the epitome of perfection. Or so he thought. Dib burst into laughter at the sight of it, causing Keef to awkwardly laugh as well.

“What is that, Zim? It looks hideous!” Zim huffed. “I based it off of you, actually!” He quipped, grinning when Dib’s mean smile dropped into a scowl.

“Yeah, well, I’m gonna make my pig look like you. Also, I don’t wear blue shoes!” Zim rolled his eyes. “You wear those hideous black boots, I know. I just felt that blue would suit your disgusting feet better.” Dib’s raised a brow.

“You know you just sorta complimented me, right?” Zim was growing tired of his face heating up this much. He hid his blush with an angry wipe of his face.

“No I didn’t! You lie, Dib!” He screamed, pressing the start button. Keef let out a cry. “I wasn’t done yet!” He whined. Dib groaned. “I wasn’t either, Zim.”

Zim felt a smug smirk spread across his face. “Yes, well, you should’ve known better than to insult Zim.” “I didn’t even–” “The mere suggestion that I would compliment my mortal enemy under any circumstance is a great offense.”

Dib went silent at that, murmuring something under his breath. The game went by silently and awkwardly, mostly due to Keef interjecting randomly when the two began to speak to one another.

Zim cheered happily when he managed to shove Dib off of a floating platform, sending his pig to its untimely end.

“What the heck, Zim!?” Dib snapped, lunging for his controller. “Hey! Stop that, that’s cheating!” Zim screeched, chest puffing happily as the two began fighting.

Keef giggled as the two swiped at each other over him, souring Zim’s mood instantly. Zim leaned back over to his side of the couch, as far as he could get from Keef, and grumbled.

“I’m bored of this game.” He snapped, turning away and throwing the controller over his shoulder towards Dib. He grinned when he heard the loud clack of it hitting him in the head.

“Ow! Ugh. You know what, Zim.” Dib began, tone dangerously dark. “I have an idea for a game.” He stood, motioning for the two to follow him up the stairs.

Zim felt anxiety bloom in his chest, sticking close behind Dib and eyeing his hands. He had no weapons, so he couldn’t be planning to hurt him.

They entered Dib’s room, and Zim flinched when he heard the door shut, the lock sliding into place.

Dib strode over to his bed, turning as he tossed himself on it, smiling down at Keef and Zim, who had chosen to sit on the floor.

“Let’s play a game of truth or dare.”

Zim stared dumbly at Dib. “What? What’s that?” He huffed, crawling away from Keef as he tried to scoot closer towards him. Keef perked up at Zim’s question.

“Oh! Oh! I know! You have to pick between answering whatever we ask you honestly, or doing whatever dare we give you.”

Dib rolled his eyes, but nodded all the same. “And you have to answer with the truth, Zim.” He added.

Zim narrowed his eyes. “Of course. What are you gonna do, ask me if I’m an alien?” Zim mocked, sticking his bottom lip out and batting his eyes at Dib.

He felt a vicious pleasure in his chest at the sight of Dib’s ears and cheeks reddening, and he cackled as he finally stood and walked over to the bed. He sat beside Dib, ignoring the hurt look in Keef’s eyes.

“Who wants to go first?” Dib drawled, his eyes filled with boredom. “Ooh! Me! Me!” Keef squeaked, beaming when Zim waved at him to ask. “Okay, Dib! Truth or Dare?” He asked.

Zim was surprised. He had expected Keef to question him first, and dare him to kiss him or something disgusting like that. Dib thought for a moment. “Truth.”

Keef’s smile never faltered as he asked, “Do you like anyone?” Dib seemed to freeze, body stiffening besides Zim’s. Zim peered curiously over at him.

He knew enough now to know that usually this question pertained to crushes, the genuine kind, not the one he’d experienced with Tak.

Dib rolled his eyes as he spoke, “I guess?” Keef giggled, his little legs kicking against the ground. “Your turn, Dib!” Dib instantly whirled around to face Zim.

“Okay, Zim. Truth or dare.” Zim swallowed, nerves rising. He wasn’t scared of Dib, but he was scared of what he’d make him do. He wasn’t particularly eager to find out what he’d try to make him talk about either.

He decided to go for the current lesser of two evils.

“Truth.” Zim didn’t miss the look of disappointment in his eyes, and he internally sighed with relief. Dib’s eyes slowly trailed up and down Zim’s body, and Zim realized he was looking for a question about his anatomy to ask.

Dib seemed to settle on Zim’s PAK. “Why do you need your PAK?” He asked. Zim didn’t want to divulge information to Dib, but he was trapped, considering Keef was there.

“It….contains important information and life sustaining materials.” He mumbled, the answer as vague as he could make it. Dib nodded to himself. “Okay, your turn.” Zim smirked.

“Truth or dare, Keef.” Dib’s eyes widened in shock. He had clearly been expecting Zim to choose him. Keef’s eyes brightened. “Oh! Dare, Zim. You know I’d do anything for you.” He gushed, eyes fluttering as he finished speaking.

“I dare you to run all the way outside and back….” Zim looked around Dib’s room. “And you have to…uh…” He saw a little figure of a detective character from some show Dib liked on top of his desk.

“And you have to throw this in the grass and then find it.” He snapped, standing and walking over to snatch it off the desk, walking back to Keef and handing it to him.

Keef nodded eagerly, rushing out of Dib’s bedroom and thudding loudly down the stairs. Zim snorted, crossing his arms and turning around to face Dib.

“Now that he’s gone, and should be for a while, how about you go next?” He said with a smirk, amused at how well his plan had worked.

Dib rolled his eyes, but a light pink dusted his cheeks and Zim could tell he was slightly grateful. “Fine. Truth or dare, Zim?” He asked, standing up and brushing past Zim to close his door.

Zim sat back on Dib’s bed, wrinkling his nose as he caught a whiff of Dib’s dirty laundry hiding underneath the blankets. “Truth.” Dib whirled around, a sharp gleam in his eye as he asked, “Are you and Keef a thing?”

Zim’s eyes narrowed. “A thing? What do you mean?” Dib slammed a hand against his face, dragging it down slowly. “Ugh, Zim, I mean…are you two dating? Do you have a crush on him? Stuff like that.”

Zim’s eyes widened and he furiously shook his head. “Oh no. I would never date Keef. He’s absolutely repulsive, you know.” He waved his hand at Dib, watching carefully as he walked over to sit beside him on the bed.

“Oh. Okay.” Dib replied, his tone disinterested and bored, yet the small smile on his face revealed otherwise. Zim felt warmth rise in his chest.

Clearly Dib was angry at the idea of him and Keef being a “thing” as he said, and despite himself, Zim was pleased by that.

He decided Dib needed to be punished, however, for even considering that Zim would stoop as low as to be mates with the disgusting Keef.

“Truth or Dare.” Zim spoke. “Uhh…dare.” Dib responded, hand rising to push his glasses further up his nose.

“I dare you to sit perfectly still until Keef comes back and not do anything unless I give you permission.” Zim responded, standing and walking to be in front of Dib.

“What-?” Dib began, cutting off with a choke as Zim straddled his hips, wiggling around as he settled on his lap. “Z-Zim, that’s not how dares wor-!”

“Shut up, Dib.” Zim snapped. Dib’s mouth clamped shut, eyes wild and shifting all around. Zim stared at his face, admiring the way the light pink began to darken.

“Dib, it is truly insulting that you would ever believe I’d be mates with Keef. I’ve got to remind you exactly who I am. I am Zim!” He screeched, ignoring the way Dib snorted at his corny statement.

He bent forward, letting a hand slide down Dib’s sternum and gently pressing against the growing lump in his pants. “Do you ever take these off?” Zim murmured, mostly to himself.

Dib gave a curt reply, “Not unless I’m going to sleep.” Zim rolled his eyes, shoving Dib backwards onto the bed. Dib willingly went, sending a jolt of electric energy up Zim’s spine.

He scooted forward, allowing his ass to rest against Dib’s pelvis. “I’m gonna start now. Remember, you can’t do anything. That’s how the dare works.”

Dib swallowed nervously, glancing away as he mumbled, “Fine.” Zim began to grind against him, hands gripping the sheets as he struggled to set a proper pace.

Dib let out a quiet groan, biting his lip immediately after as he glared at Zim. His eyes were sharp and angry, but lust was slowly drowning the other emotions out.

Zim began to grind faster, moving his hands to Dib’s chest and gripping his shirt—earning him a moan and a buck of his hips—to hold himself steady once more.

He struggled to hold back the moans and grunts that were building within him, hissing when Dib made the mistake of moving his hands to cup his ass.

They dropped immediately, digging into the sheets and grabbing fistfuls as Dib whined. Zim had realized something about Dib during all of their mating rituals. He really liked touching Zim.

Depriving him of that would be a fitting punishment for his insulting belief about him and Keef. Zim picked up the pace, allowing his moans to slip through as he ground hard against the bulge in Dib’s pants.

The bed creaked noisily and Dib began to crow like a bird, whimpering and mumbling utter nonsense to Zim. “Z-Zim…hah…p-please…fuck!” He whimpered, yelping as Zim delivered a particularly harsh thrust against him.

“Shut up, Dib. I like you better when your noise hole is only letting out moans.” Dib snorted, yet his ears reddened all the same. “You’re terrible at dirty talk.” He quipped.

“Says the one who just got more erect.” Zim shot back. Dib’s mouth clamped shut at that, and Zim rewarded himself with a victorious thrust that left both of the boys groaning.

“F-Fuck…Zim, please, just take them off already!” Dib moaned, and Zim watched in amusement as he squirmed, hands obediently at his sides, legs stiff despite everything.

Zim scooted further back on Dib’s legs, hooking a finger around Dib’s waistband and tugging it downward. His erection popped out, tapping Zim against the lips.

Dib winced, biting his lip as Zim wrapped his claws around him. “H-hey! Be careful with that. Don’t scratch it or anything.” Zim narrowed his eyes at Dib, dragging a deliberate claw from the tip to the base of his dick.

The reward of seeing Dib shiver and whimper was like none other. Zim decided he should top more often. He continued lazily dragging his claw up and down, waiting for Dib to begin rambling once more.

He was rewarded when Dib let out a quiet whisper. “..se…k…m…” Zim smirked. “What was that?” “Please…” Dib began, trailing off as his entire face became a bright pink.

Zim blinked, continuing his ministrations absentmindedly. He could outwait Dib any day, and today he would. Dib groaned, eyes squeezing shut as he shouted, “Please suck me!” Zim froze, surprised at the way his spooch had leapt.

He could feel himself slipping out below, and he coughed, closing his eyes and gripping the sheets as he tried to calm down. He wasn’t going to be fucking Dib, he didn’t need that thing down there.

He couldn’t help but imagine it though, and he let out a groan as he leaned forward, kissing Dib’s tip. “What a good little pig slave.” Zim murmured, opening his mouth and allowing his long serpent like tongue to swipe the slit a couple times.

Dib whined, fingers holding the sheets in an impossibly punishing grip. Zim took the tip in his mouth, trying to remember what the porn videos had shown him. No teeth was an important rule, he recalled.

He smiled around Dib, looking up at him with mischief in his eyes. The look of confusion and brief fear was all the encouragement Zim needed before he sank all the way down, his tongue uselessly pressed against the shaft.

Dib stiffened and Zim glanced up, confused. Had he hurt him? His answer was clear when he saw the hand clamped tightly over Dib’s mouth, his eyes squeezed shut with tiny drops of tears pricking at the edges, and lastly, his bright red and sweaty face.

Zim thought about scolding Dib for covering his mouth, preventing him from hearing his sweet mating calls, but he relented. He’d tortured him enough today, he thought.

Well, not entirely.

He wrapped his tongue around his length, squeezing and sliding it up and down as he bobbed his head, smiling around him when Dib let out a loud cry of pleasure.

“Hhhhhffnn….j-just like I dreamt..” he whimpered, and Zim blinked in confusion. He pulled away with a pop, satisfaction ripping through his chest when Dib’s hips bucked upward, chasing the pleasure he’d been suddenly deprived of.

“What dream?” Zim questioned. “I- No. I didn’t..” Dib trailed off, eyes averted. Zim scowled and pulled further backward, refusing to touch him until he’d gotten his answer.

Dib groaned before quickly mumbling, “I may have had a wet dream about you sucking my dick last night, okay? Now can we get back to— hah..” Dib cut off with a sigh as Zim sank his mouth back down, his gloved hands gently caressing his inner thighs.

Zim loved the way Dib wailed in pleasure, the pathetic expression on his face, the little whimpers and whispers of praise that spilled from his lips, all of it was Zim’s to hear alone.

Dib was his.

Dib had always belonged to him, since the day they’d first met. He wanted to claim Dib as his mate so badly, but he knew they were both not physically matured enough for mating marks.

As soon as they were, Zim would mark him. Regardless of whether or not Dib wanted it, he belonged to him. His head began to bob even faster, his tongue winding around Dib’s cock and tugging, playfully flicking at his slit every couple of seconds.

This seemed to unleash something in Dib, as his hands flew up from the sheets and tangled into Zim’s wig, and he moaned more freely than before. “Y-Yes..! Yes, Zim, just…hah…just like that!”

Zim came to the conclusion that this was the part of the wet dream Dib had aforementioned—not that he knew entirely how a dream could be wet—and continued despite Dib breaking the rule of moving without Zim’s permission.

Dib babbled utter nonsense about how good and amazing Zim was, and he couldn’t deny how proud he felt to see his enemy a trembling mess simply from his touch, praising him even though he had a burning hatred for him.

Zim felt his face warm even more than before, going as fast as he could and staring directly up into Dib’s watery unfocused eyes. “Zim…Zim! I..I lo-!” The two flinched, spell broken when the distant sound of the front door slamming open rang out.

“Zim! Dib! I did it!” Keef shouted, the thud of his footsteps getting closer. Zim pulled away with a pop, causing Dib to yelp.

They both scrambled to dress again, Zim settling comfortably beside Dib while Dib yanked his pants up and around his hips once more.

He stumbled as he did so, landing directly into Zim’s lap. Zim bit his lip, his tendril stirring from the pressure. Dib cursed, and as he moved to stand, the bedroom door flew open. Keef froze, taking in the scene.

Zim wondered if one day Keef would take the hint that Dib was his mate. They’d been caught by him in numerous compromising positions, yet Keef still foolishly held onto the idea that he and Zim would be together.

Truly disgusting. Keef frowned, but went inside and sat down in front of them silently anyway. Dib quickly moved to sit further away from Zim on the bed, an embarrassed flush reddening his already pink ears.

Keef thought for a moment before turning to Zim. “Truth or dare, Zim!” Zim thought for a moment. “Truth.” Keef smiled as he asked, “Do you have a crush on Dib?” Zim blinked.

Dib burst into laughter, the sound cold and mean. “Zim? Having a crush on anyone, much less me? Ask a real question, Keef.” Keef remained silent, his fake smile straining the longer Zim chose not to speak.

Dib’s laughter awkwardly faded and he turned to stare at him. “Uh…Zim?” Zim felt cold fear curling up his spine, wrapping around his squeedily spooch. This was terrible.

In the heat of the moment he’d have been proud to proclaim Dib as his mate, but without
the mind numbing haze of arousal, the aspect of actually admitting it brought a kind of fear Zim hadn’t felt in years.

“Z-Zim doesn’t do the stupid human courtship things.” He replied. He hoped the answer was vague enough to protect him from being further questioned. Dib’s eyes narrowed, and Keef seemed to stiffen further.

“That—” Keef began, cut off by Zim turning to Dib. “Truth or Dare.” He snapped. Dib thought for a moment. “Truth.” Zim raised a hand to his face, covering his lips as he thought of a question to ask.

“How often do you take photos of me?” He asked, trying to steer the conversation away from petty human romances and the like.

Dib’s expression remained bored as he replied, “Every day.” Zim hated the way his spooch flipped at that. “You creep.” He growled, scooting further away from him on the bed.

Dib smiled, leaning forward towards Zim as he asked, “Truth or Dare?” Zim scowled, the challenge in his tone not having gone unnoticed. “Dare.” Dib stood up off the bed. “Let me examine your tongue.”

Zim stared at him. “What?” Dib rolled his eyes, arms crossing in front of him as he spoke, “I said I want to examine your tongue? Just stick it out and let me look at it.” Zim growled, face flushing as he glanced over to see Keef’s interested eyes watching him.

“Fine.” He stood, opening his mouth and allowing his tongue to slither out. He glared at Dib, maintaining eye contact as he reached forward and gently wrapped his fingers in Zim’s tongue.

Zim yelped when Dib yanked on it, pulling him closer. He placed a hand on Dib’s arm as he shoved a hand halfway into his mouth, holding it open as his other hand was wrapped further by Zim’s tongue.

“Geez, Zim. Your tongue is long.” Zim let out several choked noises, gagging when Dib shoved his hand in his mouth and pulled even more of his tongue out. It squirmed around his fingers and coated Dib’s hand in a light pink saliva.

“Heh, gross.” Dib chuckled, slowly pulling his hand back and letting out amused laughter as Zim’s tongue slowly unwinded around his hand. Zim glanced over at Keef, startled to see the dark expression there.

Dib suddenly shoved his hand back into Zim’s mouth, and he choked. “Ghk— Dib-!” Dib shushed him, hand stroking his cheek in a surprisingly gentle way. “Let me look.”

After several minutes of oral torture Dib seemed satisfied, pulling away and wiping his hands on his pants. “Alright, I’m done.” Zim whined, his jaw and tongue sore from being held open and tugged at.

He would get his revenge on Dib, he was sure of it. Dib glanced towards the clock on his desk and frowned. He turned to Keef. “My Dad’s gonna be home soon. You gotta go.” Keef sighed sadly.

“Oh, okay…Zim, do you wanna walk home together?” He asked, eyes sparkling hopefully. Dib cast a curious glance in Zim’s direction, but Zim avoided it. He had no time to answer for his lies.

“No! I have…uh..” Zim scrambled for an excuse, flinching when Dib stepped forward. “My Dad told Zim to stay here so he could talk with him when he gets home. It’s super important, and he doesn’t want anyone to bother them. Best for you to leave, who knows how long it’ll take.”

Keef smiled sadly. “Oh, okay, guys! I’ll see you at Skool on Monday then!” He turned and raced out of the room, his footsteps on the stairs loud as he left the house. Zim sighed with relief, startled when Dib turned to him with a glare.

He seemed to want to say something, but he just sighed and walked out of his room. Zim considered following him, until Dib’s phone buzzed. Dib’s phone never buzzed. Not unless Zim sent him a message. And he hadn’t sent him one.

He scrambled for it, opening it up and typing on the keypad of Dib’s phone to open up his messaging app. As he feared, an unknown number that was all too familiar to Zim had sent Dib several messages. Zim looked through them.

The first was the blurry video of him in the bathroom, the other messages explaining what he was doing and why. Zim felt enraged. He had done everything Keef had asked and he still dared to betray him?

Zim blocked Keef’s number on Dib’s phone and reached for his own to do the same, deciding that he would simply stick to Dib’s side to prevent Keef from getting to him and showing him the video.

“Zim?” Dib called from downstairs, startling him. “What, insolent dirt monkey!?” Dib’s scoff was loud enough for Zim to hear as he replied, “Dad and Gaz are home. They brought pizza, hurry up and come downstairs.”

Zim stared at his phone, opened on Keef’s contact and prepared to block him. He pressed the button, tossing his phone beside Dib’s and raced out of his room. “I don’t want any of your greasy earth pizza!” He snapped as he stomped down the stairs.

On the bed, Dib’s phone buzzed. 1 new message from an Unknown Number.

Chapter Text

[Zim]

Zim was anxious. He knew that Keef wasn’t exactly the type to give up so easily. He wanted to find a way to block all numbers besides his own on Dib’s phone. Dib really only needed his number anyway.

He was snapped from his thoughts by Dib shoving a slice of pizza into his face. Zim growled, opening his jaw as wide as he could and shoving the entire pizza—along with Dib’s hand—into his mouth, clamping it shut afterward.

Dib yelped, yanking his arm back in an attempt to escape Zim’s punishing bite. “Jeez, Zim if you didn’t want the pizza you could’ve just said so!”

Zim crossed his arms, ignoring the burning of the greasy triangular food as he chewed and swallowed. “You were shoving it down my throat, I had no time to.” Dib opened his mouth to retort, only for a loud slam to cut him off, making the boys jump.

They turned, cowering as Gaz’s furious gaze pinned them to their seats at the table. “If you two don’t shut up in the next five seconds, I’ll make you wish you were never born.” She spoke coldly, raising the hand that held a slice of pizza and crushing it into a red, saucy and cheesy goop that spilled from her fist. “Got it?”

The two nodded quickly as Membrane gave a hearty laugh. “You all get along so well!” He boomed as he made his way towards the entrance to the downstairs lab. “I have to return to work on my latest project, designed to end homelessness, if you hear screaming, don’t come downstairs!”

He opened the door and headed down, leaving the three to themselves. Zim wanted nothing more than to destroy the Membrane household.

His antenna perked beneath his shabby wig when Gaz spoke, “I’m going to bed now. If I hear even a single shout, thud, or anything loud, I’m going to come kill you two myself.” She scooted her chair out, leaving her dirty plate on the table, and made her way up the stairs, tapping away on her Game Slave.

The silence that followed was tense and awkward, and Zim wished for nothing more than Dib to announce the sleeping part of the sleepover. “Uh, well…I’m gonna get started on dishes, Zim.” Dib muttered, making his way towards the stairs.

“I forgot something from my room so I’m gonna go get it. Don’t make any evil weapons out of the forks and plates while I’m gone.” He mocked, smirking when Zim’s face scrunched up with irritation.

Zim watched quietly as Dib disappeared upstairs and stood, grabbing his plate and tossing it towards the sink, antennae twitching when it shattered upon impact. He waited for the familiar sound of Dib’s angry scream and footsteps stomping down the stairs, but there was nothing but silence.

Zim’s gut twisted.

He’d blocked Keef’s number and deleted the chat, he was sure of it. Yet the silence that came from Dib’s room left Zim’s spooch twisting and he bolted for the stairs. He tripped on the top steps, scrambling for purchase before falling on his face.

He lifted his head, glaring at the open door to Dib’s bedroom. His PAK legs extended and lifted him to his feet and he walked quickly towards the door.

He peeked inside, frowning when he noticed Dib standing with his back turned in the dark. “Dib?” He called, carefully approaching him and reaching a gloved hand out to touch his shoulder.

Upon contact, Dib flinched and whipped around, pushing Zim away. “Hey!” Zim began, pausing when he noticed the distant look in Dib’s eyes. “Uh, Zim. Sorry, I forgot you..” Dib trailed off, before brushing past him.

Zim eyed the phone in Dib’s hands, his blood running cold. “Why are you behaving so oddly, Dib-stink?” Zim spat, keeping his tone as flat and uninterested as possible.

Dib grumbled something to himself before walking out of the room and downstairs, leaving Zim standing alone and utterly confused. He growled and checked his own phone, hissing when he saw an unknown number in his call logs.

45 calls.

Keef was demented, and Zim made a mental note to kill him later on. The sound of the water running and dishes clinking shook Zim from his murderous stupor and he dragged himself towards Dib’s bed.

He had not brought the “pee-jays” that children would typically wear, they were far too embarrassing and entirely unbecoming of an irken invader. Despite this, he found himself rummaging through Dib’s drawers, pulling one of his old shirts out from the bottom.

A dark blue shirt with a neutral gray face print that he used to wear constantly before he switched to plain gray, blue, and black shirts. Perfect.

Zim walked over to the bedroom door and shut it, yanking his tunic off and discarding his boots by the door before slipping out of his irken grade leggings. He slipped the shirt over his head, ripping the wig off and sighing with relief as his antennae were allowed to freely move.

He glanced at the near 8 foot mirror in the corner of Dib’s room, taking in the sight of himself. The shirt was so large it hung off of his shoulders, and he realized he looked rather childish and stupid.

He’d always thought that Dib was born ugly, but perhaps it was truly the fault of the clothing he wore. Zim made his way back towards the dresser to hunt for pants, opening the bottom drawer and climbing atop it so he could reach the uppermost drawer.

Dib’s dresser really was unreasonably tall, it was not Zim’s fault he couldn’t reach, and he most certainly was not short. He bent over, legs kicking aimlessly in the air as he found a pair of sweatpants that were worthy of being worn by him.

A cough from behind him made him flinch and he pulled his head back quickly, falling backward and off the dresser. He yelped as he landed on his ass, whipping his head around to growl at Dib.

“What the hell!” He snapped in irken, blush burning his face when Dib snickered. “It’s so funny hearing you cuss like that.” Zim stood, dusting himself off and glaring in his direction.

“I’ll make you suffer for humiliating me.” He snapped, walking over to Dib’s bed and climbing onto it. Dib frowned. “Hey, why are you getting in my bed? You can sleep on the floor!”

Zim scowled. He was above sleeping on the cold dirty floor of Dib’s room. He was above sleeping in his bed, even, but he had made a silent promise to compromise for the evening. “I will sleep here, regardless of what you say or do.” He spat.

Dib’s eyes flashed, and Zim only had time to let out a squeak before he was on top of him, his hands snatching Zim’s wrists and pinning them above his head. “Really? Even if I do this?” Dib mocked, holding both of Zim’s wrists with one hand as the other slid down his chest.

Zim felt his body heating up, tendril dangerously close to slipping out. “Y-Yes.” He snapped back, hating how he stammered as Dib’s hand reached just above his pelvis. “Okay, Zim..” Dib chuckled, obviously not fooled by Zim’s spectacular lie.

“You know, earlier you sucked me off, and I was thinking, why don’t I…” His hand slipped past the waistband of the baggy sweatpants Zim had hastily pulled on, fingers dipping between his folds.

Zim squeaked, hips rising to meet the palm of his hand. “Return the favor?” Dib finished, and Zim couldn’t help but snort. “That was stupid and corny, Dib.” Dib rolled his eyes, fingers working against Zim’s inner walls.

“Yeah, but you clenched so tight my fingers feel broken, so I’d say it worked.” Zim let out an airy sigh, warm tingles of pleasure zipping up his spine. “N-No it didn’t.” He lied.

Dib hummed, thrusting more sharply at Zim’s denial. “Well, if it doesn’t feel good, I could always just stop.” He pulled his hand away, and Zim cursed the smile that danced across Dib’s face when his legs wrapped around his hips, pulling him back towards him.

“No! I, uh…Zim finds it to be….decent enough. Continue.” Zim watched as Dib tried and failed to hold back his amusement and Zim drifted into the pleasant sensations as Dib went back to lazily thrusting his fingers inside of him, curling them once he reached the very back of Zim’s…he suddenly paused.

“Zim, what is this?” Zim, who’d been preoccupied with whimpering and biting on his arm to hold back his louder moans, glared down at Dib. “What do you mean?” He grumbled.

Dib gave an exemplary thrust of his fingers, and Zim responded with an airy gasp. “This. Humans, we have either…you know the anus for guys, and then girls have like…you know..” Dib fumbled, and Zim felt amused as his face reddened with embarrassment.

He shrugged, but gave Dib a response anyway. “Irken anatomy is different. I have what is closest to a filthy stink woman’s womb, in this case, but I also have a penile shaped appendage in case of sexual intercourse with intent to mate, not that we Irkens need it. We are a far superior race and can reproduce just fine without it.”

Dib’s eyes widened and he slowly resumed his thrusting as he asked, “Does this mean that you can, in theory, get pregnant?” Zim hissed, pushing back against each thrust. “Y-yes…I..guess? It’s not limited to gender due to the fffuh..fact that females in our race are not born very often.”

Dib nodded, pulling away from Zim as he rushed to his desk. “Uh- Hey! Dib-Stink what the hell are you doing!?” Zim shouted angrily, lifting himself off the bed and marching to his side. Dib had pulled out a small notepad and pen and begun scribbling down notes about Zim’s anatomy.

Zim couldn’t tell if he felt insulted or complimented by this, and instead decided he would drag Dib back to the bed and force him to continue the pleasant finger thrusting he’d been doing before.

He gripped the back of Dib’s collar, yanking him roughly out of his chair. Dib gagged, hands flying up to pry at the front of his shirt. Zim pulled him towards the bed, tossing himself backward and settling back on the sheets.

He knew he should stop, he was trying to distance himself from him after all, to stop all of this, but Dib was the only thing that could ever get him off it seemed. That, and he hated to admit that he wanted it to be Dib who did these things with him.

As disgusting as mating rituals were, with him they felt almost okay to Zim. Dib chuckled and settled back between Zim’s legs, gently prodding them apart. “Okay, okay, Zim. Give me a second..” Zim whined as Dib’s tongue lapped at his folds, his antennae twitching wildly.

“D-Dib, wait….” Dib looked up, blinking in confusion. Zim hated the way his stomach twisted as he felt his dick curl inside of him, desperate for release. “I…” He began, trailing off. It was one thing to explain to Dib what his anatomy was, but to have him see it? The mere thought was mortifying.

Dib seemed to catch on, and he pulled away, standing up and walking over to his dresser. “Give me a second, I have a blindfold. I got one after the last time.” He murmured, his annoyance over Zim’s excellent shorts ripping skills apparent in his tone.

He slipped a bright pink strip of fabric from the top drawer, walking back towards Zim and holding it up to him. Like an offering. Like Zim was a God.

Dib glanced downward, his brows furrowing as his cheeks reddened. “Uh, Zim? You’re kinda…leaking a lot?” Zim, who’d been swept up in staring at the blindfold, blushed as he realized just how turned on he was by the notion of tying the blind himself.

“Sh-Shut up, stink boy. Give me that!” He screeched, snatching the blindfold from his hands before sitting upward and scooting close to Dib, quickly tying it around his eyes. He couldn’t help but stare at Dib’s slightly parted lips, wanting nothing more than to steal them for his own.

That was too intimate, however. He was not supposed to be courting the Dib any longer. This was not anything that the humans would call “romantic”, it was mere sex for pleasure. He was using Dib, really. And from the way that Dib had so readily bought himself a blindfold, it appeared he liked being used.

This was nothing. This meant nothing.

It was similar to what boys around Dib’s age experienced all the time, it was just puberty. He pulled away, flopping back on the bed. He groaned as his dick finally freed itself, instantly reaching toward Dib’s hand that rested on his hip. “Well?” Zim snapped.

Dib flinched, leaning forward carefully. He bumped Zim’s right thigh, letting out a nervous chuckle as he dragged his face upward and towards Zim’s ever so eager tendril. It jabbed his lips as he finally grew near, and Zim smirked as Dib yelped in surprise.

He settled in a position that was comfortable for him and slowly licked at the tip, making a face one would if they had just swallowed a lemon whole. “You feel funny.” He noted. Zim pretended his chest wasn’t tight as he asked, “Is that a problem?”

Dib perked up at that, jerking away to stare in Zim’s direction. “No. Never.” He spoke, his tone so genuine and earnest that Zim felt almost guilty for having ever asked. “Y-Yeah, well…shut up and suck it already so we can get this over with. I’m getting bored!” He grumbled.

Not entirely a lie. He was getting very bored of constantly feeling this way when Dib was around him. Dib quietly obeyed, mouth opening warily as he attempted to get a hold of Zim’s wriggling tip.

He finally remembered his hands were free, it seemed, as he gripped the base—earning a sharp hiss from Zim—and shoved it abruptly in his mouth. It extended almost instantly, hitting the back of his throat and causing Dib to yank away as he coughed and gagged.

Zim would have laughed if it hadn’t felt so good, instead settling for a choked snicker. Dib huffed angrily, taking it in much slower, pulling back to lap at it pathetically every few seconds. Zim felt irritation like a hot iron burning him, and the moment Dib’s mouth had closed around him once more, his hands flew down to grip him, one by his scythe shaped hair wick, and the other by the side of his head.

He forced him downward, cackling at the alarmed gags and choked whines as Zim’s dick slid halfway down his throat. “You seemed like you needed a push in the right direction, stupid earthworm. Don’t worry, Zim will show you exactly how you should do it…”

Zim yanked his head upward, allowing him a reprieve, dick twitching and flicking back and forth wildly at the sound of his gasps and coughs. He expected Dib to start shouting, curse at him for choking him, accuse him of trying to kill him, but all that he got was a low whine and a pleasant lap at his tip.

Zim felt himself growing mad with power. What the hell was up with Dib today? Zim groaned as Dib sank downward, attempting to reach the base of his tendril. Zim gently slid his fingers through his hair, Dib letting out a quiet yet pleased hum at the sensation.

He finally began bobbing up and down at a quick pace, eyebrows furrowed as he clearly tried to focus on pleasing Zim. He was doing a rather poor job of it, accidentally scraping Zim with his teeth and his tongue flopping uselessly every once in a while, but it was the thought that counted in his eyes.

Zim hissed and began bucking into Dib’s mouth once he finally found the right pace, his tongue finally learning how to lick around as he went. Dib froze with his face burrowed into Zim, trying to swallow around Zim’s girth. Zim gasped at the squeezing, hands flying up to grip Dib’s hair as he rambled nonsense and tried not to cum then and there.

Dib gagged, attempting to lift his head up, though Zim refused. He began to panic, clearly, as his hands reached up and squeezed Zim’s hips. Reluctantly, Zim let go, and Dib pulled back with a gasp, coughing and clutching the sheets on either side of him, his glare obvious despite the blindfold. “You asshole!” He snapped.

Zim smirked. There was the Dib he knew.

“What? I couldn’t help it, you felt like the perfect little sleeve for my-” “Shut up!” Dib snapped, his ears a bright stinging red that only served to make Zim harder. “Why don’t you make me?” Zim slowly spoke, tone low and dark.

Dib seemed frozen in place for a moment, and Zim’s confidence drained and he felt embarrassment start to creep in. “U-Unless you-” Dib stood up on shaky legs, startling Zim. He slowly crawled on top of him, hooking his legs around Zim’s hips and sliding his own pants downward.

Zim tried not to stare at Dib’s very apparent erection, but it prodded his leg and his eyes snapped downward on instinct. “Okay, Zim. Shut up.” Dib whispered, slowly leaning downward. Zim tried to hold back a snicker, Dib was totally gonna miss his face if he kept going like this, but he scooted to the side and allowed their lips to meet.

Zim’s arms, which had been laying stiffly by his side, flew up as he cupped Dib’s face with his hands. Dib let out a pleased grunt, and Zim felt himself grow dizzy. Dib wasn’t letting him catch his breath for even a second, and Zim loved it.

He wanted more, needed more, wanted to keep kissing Dib, keep holding him, he wanted to destroy him and the bed they laid upon, he wanted, he wanted, he wanted.

At least, until Dib’s phone buzzed. Zim froze and glanced over at where it laid on his desk. He gripped Dib’s shoulders, uncharacteristically gentle as he moved Dib to the side. He stood off the bed and lunged for it, fear bubbling in his stomach as he realized it was a video sent from an unknown number.

He quickly deleted it and tossed it back onto Dib’s desk. Dib let out a huff as he climbed off the bed and stood, obviously confused by Zim’s sudden behavior. “Are you alright, Zim?”

Zim whirled around, growling. “Yes, of course I am.” He snapped, shoving his head through the shirt he’d stolen from Dib, dressing himself as he made his way towards the bedroom door. Dib slid the blindfold off, calling out in alarm when he saw Zim rushing away, “W-wait! Didn’t you wanna fini-?” “No!” Zim snapped, bursting through the door and down the stairs.

He headed towards the bathroom, bursting inside and slamming the door behind him and sitting on the toilet to sulk. Keef was a monster. A stupid, stupid monster. Zim wouldn’t let him get away with this.

He looked at his wrist, knowing that with a single tap he could send out one of his latest built robots of destruction to simply kill Keef. It would cause a lot of destruction, though his problems would be solved. But his thoughts went back to Dib, who he’d abandoned upstairs, and he settled for pouting until he felt better.

[Dib]

Dib stared at the door that had been slammed shut in his face, blinking furiously. Every time they’d make progress, every time Zim’s walls would start to come down, something would happen and he’d tense up again.

He thought for a while as he got dressed about what the potential trigger could’ve been this time. He hadn’t said anything weird, he thought. As he slid his pants back on, he realized what it was.

This time it had something to do with his phone. He turned around and snatched it up, opening his messages and digging around. He opened the recently deleted messages and froze.

35. Why was there 35? He’d only deleted 7.

He frowned at the most recently deleted one, a video. He clicked on it, freezing at the familiar sound of Zim’s moans. He quickly exited, checking the contact. Keef. Keef? He opened the video again, narrowing his eyes as he watched the grainy footage.

It was clearly being taken without Zim’s knowledge, and thus, his consent. The words Zim were moaning–his name, over and over–stirred Dib’s dick, but his arousal faded as soon as he remembered that Zim had done this privately for a reason.

He frowned. For a reason. Zim had been acting off lately, hanging out with Keef more, allowing him to interrupt their arguments and even demanded he be allowed to crash their sleepover.

Dib’s chest became tight and his blood felt like ice as he considered the possibility that Zim was being blackmailed. Zim didn’t like admitting when he was wrong, or admitting to caring about things.

The last time Dib had even insinuated that Zim might care for GIR as more than an evil henchman, he and the poor trash can of a robot had been knocked back a solid hundred feet by a “brain melting grenade” Zim had created.

It made sense that he wouldn’t like admitting that Dib was who he thought of when touching himself, it was far too personal and intimate, even for the sex crazed alien. But Dib had been fine with that.

He was content knowing deep down that Zim thought those things, because it was something only he could comprehend. He was special to Zim, the same way Zim was special to him. Yet, Keef had ruined it. Tainted it, even, with his disgusting perversion, his blatant lack of respect, and now Dib was losing Zim and whatever it was they were slowly building together.

He’d already dealt with all of Keef’s insane texts, the ones in which he insisted he had evidence of Zim’s “true love for him”, but knowing it was a video he’d taken in secret and used to harass Zim with only angered Dib more.

He gripped his phone in his hand, glancing back towards the door. Yes, there was time. He could do it. He slid his finger over the contact, removing it from the blocked list. He considered texting, but decided a call would move things along faster.

As his phone rang he had only one thought. He had always wanted to test his theory about turning human blood into tiny coffee beans.

Later on, Zim returned to the bedroom, looking tired and defeated. Dib had long since settled in his bed, having turned all the lights off and gotten himself snug and comfortable under the covers.

Zim seemed to consider crawling in next to him, before slowly dropping to the floor and curling into a ball. Dib couldn’t stand it.

He grabbed the blanket and pulled his pillows off his bed, ignoring how Zim flinched and shot upward at his movement. He dragged them onto the floor, throwing the blanket over himself and Zim as he handed him a pillow and placed his own under his head.

He silently fluffed it up to his liking, before settling down on it and closing his eyes. He nearly yelped when he felt himself being lifted, and he cried out when Zim tossed him back onto the bed. All of the freshly messed up sheets were laid neatly back on the bed, and Zim crawled in beside him.

His heart warmed at the way Zim avoided his eyes, at how Zim carefully positioned himself in a way where Dib could spoon and cuddle him, baring his back–and thus himself–to him.

Dib took the opportunity of course, and slowly slid behind him as he moved to put his arm over Zim’s chest. However, the more he moved his arm, the louder a certain clicking noise became. Dib realized it was Zim’s warning.

He slowly positioned his arm this way and that, finally finding the place Zim wanted as he rested his arm over Zim’s hip.

They remained silent the whole time, with the exception of Zim’s admittedly amusing clicks and chitters, and Dib sighed with relief when he recognized the soft whirring of Zim’s PAK, a sign he was asleep.

He thought for a while about what he had just done. He didn’t feel guilty in the slightest, and he hated to admit that it worried him a bit. Had Zim rubbed off on him? Or was he always this way? He glanced down at Zim’s peaceful expression and smiled.

It didn’t matter. It was all gonna be worth it, anyway.

Chapter Text

[Zim/Dib (kind of)]

When Zim awoke, he found himself staring directly into Dib’s eyes. “Ah, finally you’re awake, Zim.” He mumbled, turning his back to him. Zim sat up, gingerly holding his head.

His wig had been removed, and his antennae twitched as he looked around. There was a large metal door that led into the room with a small glass window, and the entire room was painted a dark gray.

He glanced around and noticed photos of Gaz and Dib plastered on the walls, and he finally recognized his surroundings to be a room in Membrane’s lab.

He had been laid down on a small light purple couch, and as he looked past Dib, he noticed what appeared to be a large glass observation window. Inside of the room was a single white bed, padded walls, and Keef. Zim paused.

Keef?

Dib turned, and only then did Zim realize just what he was wearing. He wore a floor length lab coat, and goggles rested over his glasses, smooshing them against his face. Zim also noted Dib’s long black gloves and a mask covering his mouth and nose.

Zim finally held Dib’s gaze, a feeler twitching as he began to speak. “I figured you’d wanna see this, Zim.” He hummed; face eerily blank.

He turned and began pressing buttons on the control panel that rested before the window. Zim crawled off the couch, standing beside Dib and analyzing the controls.

His PAK instantly translated most of the labeling and he was technologically aware enough to have a vague idea of how most other buttons worked. “See what?” Zim finally replied, his voice hoarse.

His eyes found Keef’s, and he was surprised by how terrified the red head looked. Dib seemed to take note of Keef and Zim’s eye contact as well as he suddenly slammed a fist against the glass, startling Keef and sending him scrambling into a corner.

Zim totally hadn’t flinched, and he absolutely wasn’t scared, but he took a precautionary step to the side, just in case Dib felt like wrestling.

“You know, Zim,” Dib began, his voice terrifyingly calm compared to his aggressive behavior, “If you were being blackmailed by Keef, you could’ve just told me instead of socking me in the face.”

Zim’s breath caught in his throat, and he froze, staring straight ahead. He couldn’t bring himself to look at Dib, even though he could feel his eyes boring into the side of his head.

“I…wasn’t-!” Zim began, but Dib cut him off with a hand waving in front of his face. Zim had half a mind to bite his meaty little fingers clean off, but the thought vanished as he heard a very familiar voice fill the air.

He slowly turned to stare at Dib’s phone, and the video of himself in the bathroom that was playing on it. His mouth went dry, and he felt his fists clench. He shook with rage, humiliation, and a slight fear.

“You…when did you...?” Dib paused it, slipping his phone back into the pocket of his lab coat. “Last night. It’s not important, though. I made sure there’s no trace left of it. I’ll delete that video in a second, I just want you to see this first.”

Dib pressed a button, and a vial full of a mysterious murky white liquid rose from a small hole from underneath a panel on the board. “What? What is that, Dib-?” Dib shushed him again, and Zim found himself contemplating homicide once more.

Dib took the vial, and slowly walked towards the nearly invisible see through glass door that led to the observation room. He slipped the glove on his left hand off, holding it to the scanner, and the door slid open.

Dib approached Keef casually, striding toward him almost as if he wasn’t there, but when he sharply grabbed his wrist, it became all too obvious who his target was.

Keef struggled and tried to fight against him, crying out when he was slammed against the ground. Dib stepped on his neck, foot cutting off Keef’s air as he grabbed his right arm and pulled it towards himself, his free hand reaching over with the syringe and plunging it into a vein, depositing all of the liquid inside.

Dib stepped back, casually striding out of the room and shutting the door as Zim watched in a mixture of awe and horror as Keef began to writhe, gasping for air and clawing at his own skin. He began to tear his own flesh, and blood spilled to the floor as Keef shrieked in pain.

Zim was startled, glancing over to stare at Dib. His goggles were clouded, expression unrecognizable and blank. “Is…is this-?” Zim began, only to have a hand slap over his mouth. The movement was so sudden he hadn’t the time to even realize it’d been done before Dib’s hand slowly slid back to his side.

He remained silent and Zim fumed, making a mental note to return the favor later on. They watched as Keef’s flesh began to bubble, and the blood that poured slowly began to change colors. Zim stepped closer to the glass, peering closer at Keef.

It wasn’t that the blood had changed color. What was pouring from Keef’s gashed arms wasn’t blood at all. It was… “Are those…coffee beans!?” Zim yelped, eyes widening in fascination.

Keef began to gurgle, foam pooling in his mouth as his eyes bulged and rolled back into his head. His body had begun to violently thrash around, and he had flopped on his back. His hands were still tearing off his flesh, reaching up and clawing through his own cheeks.

Zim found the display vulgar and disgusting, and yet he couldn’t help but enjoy it. Keef would most likely survive this, somehow, considering his inhuman ability to come back even after imploding into millions of pieces. The sight of him in pain was pleasant, nonetheless.

Keef’s writhing body slowly grew still, and his shrill voice died out until it was clear he was dead. It appeared that even his bones had become coffee beans, the only thing left a lumpy mess of flesh, blood, various other bodily fluids, and coffee beans. The robotic eyes Zim had placed inside of him rolled away, thunking against the far wall on the right.

Zim turned to look at Dib, wondering what exactly was running through his mind at this moment. His face remained blank, his goggles still clouded and covering his eyes. Dib began walking toward Zim and despite himself he felt his squeedily spooch beat faster, stumbling backward into the control panel as Dib leaned over him, his hand reaching up and brushing the corner of Zim’s lip.

His other hand pinned Zim in place, and his expression became clear. His cheeks were flushed, and his eyes were half lidded, his breath rough and bursting out in puffs. Zim couldn’t ignore the hardness that pressed firmly against his thigh. He swallowed, failing to stop the shiver that ran up his spine. “D-Dib...” He began, resisting the urge to grind against him.

He thought back to the first time they’d almost done a mating ritual together. Dib had been the one taking charge, and while Zim had enjoyed it thoroughly, he’d made sure Dib couldn’t do it again. Now, however, it felt like he had no choice.

He liked it.

“Don’t tell me you found the sight of…Keef arousing?” Zim scoffed, teasingly lifting his leg and grinding it against Dib’s erection. “Hah…no, of course not, Zim. It wasn’t him.” He spoke, voice low and strained. It was clear he was restraining himself, which only served to further boost Zim’s confidence.

He boldly placed a hand on Dib’s chest, letting his fingers glide downward until they rested atop the lump in Dib’s jeans. “Oh? Then who caused this, stink monkey? Hm?” He gripped it firmly in his hands, loving the way Dib’s hips twitched, bucking forward subconsciously. Dib’s breathing became even more ragged, almost animalistic.

Zim wanted to feel it against the back of his neck, wanted Dib to mark him, wanted him, him, him. “Zim, I’m really trying to be considerate of you here, but if you don’t stop, I’m gonna-” Zim shoved Dib harshly, sending him stumbling back. His eyes widened, hurt flashing for the briefest of seconds before Zim stepped forward with him, pushing him back until he flopped onto the couch.

“Dib, if you don’t take me here and now, you may never have a chance again.” Dib’s eyes widened and despite all his bravado he seemed ready to burst from his nerves. It was almost cute, though Zim found the sweat on his brow disgusting.

Dib reached out and grabbed Zim by the hips as he pinned him to the couch. His hand slid underneath the old shirt Zim was wearing, and a shiver rippled through him. Dib sighed as he lifted it up completely, kissing from Zim’s lower abdomen all the way up to his neck.

Zim’s toes curled, his hands gripping Dib’s hair as he chirped softly in response. Dib reached downward, unbuckling his pants and pulling away so he could tug them off. He tugged his boxers down his hips and tossed them to the side, and Zim didn’t hide the way he ogled at Dib’s cock.

It was just as tantalizing and threatening as he remembered, and he wondered what it would feel like to be stuffed completely full of it. He licked his lips nervously. He’d find out soon enough. Dib crawled back over to Zim, grabbing the shirt he’d pulled off of him and using it to tie Zim’s wrists together.

Alarm spread through Zim’s body, though he relaxed as Dib peppered his chest with more sickeningly sweet and gentle kisses. It was odd how caring he was being, unusual and almost boring. Dib seemed to sense Zim’s boredom, nipping along his body and glancing down at the puffy lips between his legs.

His hand gently began to massage it, spreading it open slowly as he bit down particularly hard on Zim’s right pec. A moan escaped Zim as he tugged, wincing in pain despite the pleasure from below. By now Zim knew that humans often found joy in chewing on the nipples of their fellow species, though Zim couldn’t understand why.

He had no nipples, so why was Dib doing this? Dib bit harder for a split second, earning a yelp from Zim before letting go, dragging his teeth over the marks and sitting upright. His fingers had slipped inside of Zim, thrusting lazily and scissoring against his walls. Zim let out a low hiss, his legs wrapping around Dib’s waist as the movements continued.

He wanted to resist, knowing exactly what his fingers were seeking, yet when they brushed against the underside of his tendril, he couldn’t help but grind into the touch. Dib slowly coaxed it out of hiding, his fingers running along the ribbed edges of his dick until it was wriggling between them. Zim finally released the breath he didn’t know he was holding, hazily looking into Dib’s eyes.

The glint in them was mischievous, and his smirk spelled trouble. He bent downward, grabbing the wriggling phallic tentacle, and slowly tugged in earnest, his tongue flitting around the thin tip. Zim clutched the fabric of the couch beneath him, his sharp nails shredding through it as he struggled to resist the urge to fuck into his mouth.

“D-Dib…stupid earth slave, what are you doing? You know Zim–! Hah…Zim is so g-graciously allowing you to take him…why aren’t you doing so!?” He screeched, hips bucking subconsciously as Dib began to bob up and down more vigorously. He pulled away with a tiny pop, a thin line of drool still connecting the two as he spoke, “It’s called foreplay, Zim, jeez. I know you aren’t exactly thorough when we do this, but I prefer to be.”

Zim rolled his eyes, his legs sliding up and wrapping around Dib’s neck, forcing his face to rub against him. “I don’t care, just hurry up with your “foreplay” before Zim takes you himself.” Though Dib seemed to take the threat seriously by the way he began sucking roughly once again, his dick twitching proved he didn’t mind.

He continued on for a few minutes before finally pulling away, shifting upward and spreading Zim’s legs apart. Zim admired how he seemed to tower over him, his eyes narrowed to slits as he focused on carefully slipping inside. He paused before he could fully enter, looking up at Zim warily. Anger flared in Zim’s chest, and he barked, “What!? What is it earthworm, why do you keep stopping!?”

Dib ignored his outburst, his hand sliding up Zim’s chest as he quietly spoke, “Zim, it's your first time having something like this in you.” The question was spoken more like a statement, and Zim tilted his head. His antennae lay flat on his skull, and he frowned. “Well…yes?” He huffed. Dib’s eyes suddenly became dark, and a wicked smile spread across his face.

“It might hurt when I go inside, you know.” Zim scowled again, grinding himself against the tip of Dib’s cock, snapping, “I know that! You don’t have to be gentle and baby me, Zim can–!” Dib cut Zim off quickly, “Oh! Oh, no, Zim. Hah, this isn’t me telling you I’m gonna be gentle or anything. No, I’m giving you a warning.”

Zim’s eyes widened as he realized what he meant. “Wai–!” Dib’s hips snapped forward, and all at once Zim was full, in pain, feeling immense pleasure, and horrified. He threw his head back, his arms flying upward and clawing at Dib’s back, scrambling for purchase. It was bigger than he’d expected. It didn’t look nearly half as big as it felt.

“D…Dib...!” He squeaked out, gasping as Dib slowly pulled out. He felt grateful that Dib was showing him such mercy, blinking past the tears that had welled in his eyes as he made eye contact with him directly. His heart froze, and he felt his tendril twitch. The look in Dib’s eyes was wild, and he seemed pleased by the pain in Zim’s gaze.

All at once Zim was full again, and Dib began steadily pumping inside of him once more. Zim wrapped his arms around him, his face digging into his neck as he viciously bit down. He didn’t stop until he felt the taste of Dib’s copper blood fill his senses, his moans muffled by the flesh caught between his teeth.

Dib groaned and only thrusted faster, and the world began to spin around Zim. He wanted more. Needed more. He pulled away, gasping and ignoring the way Dib’s blood dripped out of his mouth. “M-more!” He cried, chirps and clicks escaping him uncontrollably.

Dib seemed to only be fueled further by Zim’s plea, suddenly slamming him down on the couch, pulling out and adjusting to where Zim’s legs were pulled apart, and he could reach the deepest parts of him.

He slammed inside all at once, his rough pace continuing once more, and Zim shrieked with pleasure and pain. Dib’s panting and Zim’s inhuman cries filled the air, and it wasn’t long before Zim felt himself growing near his edge. “D-Dib…slow down! Zim is…Zim will-!” Dib responded with a sharp thrust, his hand moving to cover Zim’s mouth.

He leaned forward, lips brushing against the side of Zim’s head as he breathed, “Do it, Zim. I give you permission.” His tone was snarky, and the way he’d phrased it sent a shiver of rage and pleasure throughout Zim. “Y-You-! You don’t…hah…have the authority to-!” Dib responded with several sharp thrusts as he pulled his hand back to kiss Zim deeply, leaving them both spinning from the lack of air.

“Cum, Zim.” Dib commanded, and dammit did Zim do so. His claws dug into Dib’s back, dragging downward and leaving long stripes of ripped bloody flesh behind them. Zim’s slightly pink tinged semen stained both of them, and despite this, Dib continued thrusting until the hazy pleasure-filled cloud cleared from Zim’s mind and he was left with the very invasive and intense sensations.

“D-Dib- Wait, give Zim…!” He trailed off, whines turning into sharp cries of painful pleasure. “You’re gonna stay here and let me fuck you till I’m done, Zim.” His once pitchy voice was now deep, and husky yet still carried a familiar and almost pleading whine. It only served to ignite the fire in Zim once more, and he began to thrust against Dib in earnest.

“Then fuck me! Do it properly you stupid worm!” Dib responded with a growl, pulling out and flipping Zim over onto his stomach. One of his hands reached up and grabbed both of Zim’s antennae in a vice grip, tugging until Zim was facing him. “You wanna be fucked? Fine! Just don’t forget you asked for it.”

Zim cried out at the pain, but hiccupped when Dib slammed back inside of him. His thrusts were rapid and angry, hitting all of the right places and leaving Zim drooling dazedly. Being forced to look him in the eyes was humiliating in ways he couldn’t put into words, and all he could do was moan and plead, yelping when Dib tugged harder.

“How does it feel, Zim? Tell me it feels good.” Zim tried to nod, punished swiftly with a couple of quick yanks. “I-It feels good! It’s- It’s so…good...” Zim sobbed, his dick wriggling as it desperately tried to create friction against the couch. Dib seemed to take notice, and he laughed bitterly.

He shifted until he was on his knees, ignoring Zim’s screams of pain as he was held up only by his sensitive feelers. His other hand slid down Zim’s stomach until it grazed his tip, silencing Zim for a moment. “How about this, Zim.” Dib spoke darkly, and Zim trembled in fear at the expression on his face.

The submissive and loving Dib he’d known was gone, replaced by something dominant and animalistic, only caring about his own pleasure. “I’ll jerk you off while I fuck you if you agree to call me Master. I’ll even let go of your antennae.” Zim tried to nod, crying out as he only placed more strain upon himself.

“Good.” Dib snapped, his hand dropping him and slamming his face against the armrest of the couch. Blood bloomed in Zim’s mouth, and he bit back a hiss. Dib leaned forward, his back flush against Zim’s, and let his other hand roam. “You ready, Zim?” Zim nodded, albeit bitterly, knowing Dib wouldn’t let him live this down.

Dib’s hips moved at a painstakingly slow pace, as well as his hand. Zim tried to resist the urge to thrust, his restraint failing him as his hips began to violently buck forward. Dib clicked his tongue, hand pressing harder on Zim’s head as his bucking slowed to a stop. His other hand squeezed Zim painfully, leaving the alien hissing and cursing in Irken.

“Stay still. If you want me to go faster, you have to beg.” Zim swallowed his pride, weakly whispering, “Please.” A chuckle from above him left Zim blushing as Dib spoke, “Please…what?” “Pl…Please, Master.” There was a stretch of silence and Zim wondered if he’d messed up. Maybe he should’ve said his name?

He opened his mouth to speak, but all that came out was a startled squeak as Dib began thrusting in earnest. His hand tugged, squeezing at the tip and shaking when it reached his folds. Dib seemed to pause there each time, and Zim knew his curiosity was growing. The idea irritated Zim. If he paused to stick those searching and curious fingers inside of him, Zim would probably claw what was left of his ripped up back completely off.

Zim did his best to look as pathetic and pleading as possible, whimpering out, “Don’t stop…keep going...M-Master.” The words slipped off of his tongue with much effort, and the shame left him wishing he could self-destruct then and there. “Hmm…fine. I’ll leave it, for now.” The finality of his words and the subtle promise of a next time pleased Zim enough to go quiet, except for his whimpers and pleased chirps.

Dib groaned, and Zim hated that he could feel him twitching inside of himself. “Zim, I’m…fuck, I’m gonna..” Zim whined, wriggling his hips. “F-Faster. Harder, don’t be so wimpy-” Dib’s hand squeezed his dick so tight Zim saw stars, and he bucked and pulled at what was clearly his fastest pace. It was punishing, it was painful, it was amazing, and it was overwhelming.

No sooner had Dib started when Zim once more released, light pink coating them both as Dib bruised Zim’s ass with the force of his thrusts. “Fuck, I hate you so, so, much Zim!” He shouted, slamming as deep as he could, hands sliding up to grip Zim’s hips and hold him in place as he came inside.

“M-Ma- Fuck! Dib!” Zim cried, too dazed to continue their agreement, legs trembling with effort as he struggled to remain upright. Dib shook, slowly releasing Zim as he came down from his high. They flopped onto the couch, Zim squeaking at the weight of Dib on top of him. He shifted around, trying to flip him sideways, only for Dib’s hand to grip his hip.

His fingers dug into his skin as he hissed, “Zim, if you keep squirming around like that, I’m gonna fuck you again.” As appealing as the sentiment was, Zim could recognize Dib’s limit and went still, allowing Dib to adjust them to a more comfortable position. He slowly pulled out, sighing as he did so. “Damn, Zim...” He mumbled, his voice soft and his words slurred with sleep.

Zim was unsurprised and slightly amused when he heard soft snoring from behind him. He slowly sat up, prying Dib’s arm off of him and allowing it to fall at his side. He glanced around, noticing the discarded shirt he’d been wearing on the floor. He strode over, lifting it and slipping it on.

He turned back to glare at Dib, already feeling a distinct ache within him. He would make that hideous worm pay for what he’d done. Later. He turned back around, walking up to the observation glass and once more staring at what remained of Keef. He tapped his claws on the glass, startled for a moment as he realized his gloves had at some point been removed.

He whipped around, spotting them on the armrest of the couch and snatched them up, slipping them back on and heading toward the door to the room Keef had been contained in. He thought about going inside before deciding against it. Nothing in there interested him besides whatever Dib had in the syringes that turned humans into loose sacks of flesh, blood and coffee beans.

He contemplated how he would steal the formula from Dib, planning to use a less lethal version to make Dib shit or piss coffee beans for weeks. It was a solid revenge plan, indeed. He turned to the control panels, squinting his eyes as he tried to remember which buttons Dib had pressed. As he fiddled with the keys, he didn’t notice the boy behind him rousing from sleep.

He finally found the right combination to release another vial, and he reached out to grab it, only for a hand to snatch it before him. He hissed, whirling around and crying out when Dib used his free hand to catch both of his wrists. Dib sleepily analyzed the situation, blearily looking from the vial in his hand to Zim’s panicked form.

“...you just can’t stop, can you?” Dib gently placed it back in the slot, and Zim groaned in anger as it closed, the precious serum taken away from him again. In a flash he had been spun around, his arms held behind his back and his face pressed against the controls.

The result was the room in front of him slowly being filled with gas that poured from the vents. “I guess I like it better this way…I was worried you’d get all soft on me after that.” Zim hissed, wiggling his hips as he writhed against his grip. Dib chuckled, pulling Zim back, tilting his head and pressing a deep kiss against his mouth.

Zim bit Dib’s lip as hard as he could, more so to tease than actually fight, and Dib groaned into it. He loosened his grip on Zim, him taking the opportunity to leap away, PAK legs extending as he licked Dib’s blood off his lip. “Zim would never go soft for you.” He spat; a half lie he refused to think too hard about.

Dib rolled his eyes, walking past Zim and opening the door leading back into the hallway of the lab. “Yeah, sure.” Zim, annoyed that Dib didn’t rise to the bait, sulkily retracted his PAK legs, walking over to Dib and leaving with him. The pair made their way out of the labs, and Dib stretched as they entered the street.

He glanced downward at Zim, his hand rising up to grip his chin as if lost in thought. “Hey, Zim…have you ever, uh…been in a car?” He asked awkwardly, as if he hadn’t been fucking the Irken into couch pillows less than 20 minutes ago. “What? No, Irkens would never stoop so low as to use such…such inferior earth travel!”

Dib scoffed, his voice tightening with annoyance as he spoke, “Yeah, well if you wanna get back to my house any time soon you’ll have to suck it up.” Realistically, both boys knew Zim could call GIR to retrieve him in an instant. The ride might be more perilous, but it was still the faster option.

Despite this, Zim pretended to be reluctant, agreeing as if he really had no other choice. “Ugh…fine. But if you drive erratically or injure us, I will kill you.” Dib led Zim to a white, very beat up van, opening the passenger door in an act of kindness. Zim, of course, interpreted this as a sign of pity.

“Do you believe Zim is too weak to open the door on his own!?” He shrieked, slamming the door shut again before reopening it, wasting time for no purpose other than pissing Dib off. “Dammit, Zim, if it really bothered you that bad you could’ve just told me not to do it again! And don’t slam my doors, jeez.” Zim, ever the argumentative one, waved him off.

“Your humanly weak attempts at compassion are nothing but insults to me.” Dib slipped into the driver’s seat, starting up the van. He shifted to look at Zim, his eyes turning glossy and distant. “Zim, I hope you know that…” He began, but Zim merely slammed his hands on the dashboard, crying out.

“Drive! Drive you feeble human!” Dib flinched, coming back to his senses. “Jeez!? You don’t have to scream like that Zim, holy shit!” He shifted into reverse and sped out of the parking lot. The drive home was full of petty insults and jabs at one another, and despite himself, Zim found comfort in that.

He was unsure of what type of relationship the two had anymore, and he didn’t want to define it. He liked them as they were, unlabeled, no outsiders, together. As Dib stepped out of the car, motioning for Zim to follow him inside, Zim watched him for a few seconds.

“What? Something on my face?” Dib asked. Zim shook his head, brushing past him. “No…nothing.” He huffed, cursing the rising heat in his cheekbones. Dib chuckled, grabbing Zim’s wrist and pressing a kiss atop his head. Zim, infuriated, socked him in the face before bolting up the stairs, laughing at the sound of Dib scrambling after him.

If he could live every day like this, fighting and loving the Dib with no consequences, he would take it. And he will. Who’s gonna stop him now?
