Chapter Text
Dib awoke to the sound of his alarm, squinting at the clock and realizing he had slept through the beginnings of the blaring sound. He rushed out of bed, tugging on his clothing and gathering the homework he had been working on before he passed out the preceding evening. He stuffed his coursework into his backpack without worrying about crumpling the papers, pulled his shirt over his head without realizing that it was inside-out, and kicked his feet into his Converse because he didn’t have time to lace his boots.
Dib left the house just in time to catch the bus, his sister apathetic to his frantic struggles.
“Don’t you have a car?” She asked with unadulterated spite in her voice, climbing the stairs to the filthy vehicle before Dib had a chance to.
“It doesn’t have a transmission.” He reminded with a grumble, following his sister and dropping into one of the empty seats near the front because the less students he passed the better. He plugged himself into his phone, a pair of headphones signaling that, yes, he did have the Chemistry homework from Friday, but, no, he wouldn’t share. The journey to school wasn’t long enough to catch a breath in Dib’s opinion.
“Where is…” Dib paused, blinking at his empty locker. He sighed and leaned his head against the metal door just adjacent to it, knowing none of the teachers would believe him even though he’d actually had his possessions stolen from behind the flimsy padlock he’d gotten from the front office the beginning of his Freshman year. The teen stood straighter and took off his glasses, rubbing the fog from the colorless lenses.
“I guess I’m sharing with someone, today.” He wasn’t speaking to anyone in particular. Dib didn’t often have someone to talk to anyway, so it wasn’t registered by the lanky male.
“I hope Torque is here today.” Dib started towards homeroom, his bag feeling lighter without the weight of his Geography textbook. It was starting out to be a terrible day.
tick tock tick tock
Zim was already feeling bored of the school day, and it had yet to begin! He picked up his pencil and replaced it on his desk again. It still didn’t look right. “Maybe over…” he picked it up and set it angularly on his notebook, “here?” He scowled at his tenth attempt to appease himself and looked up. Time to study.
He looked at the humans as they filed in, one by one and sometimes in groupings. With a quick flick of his wrist, he lifted the pencil from his notebook and began to work.
- Becky is still ignoring Zeta. Petty arguments are common among adolescent females.
- Torque is wearing that smelly jersey from Friday. Disgusting.
- Marvin shaved his head. It is lumpy.
- The Dib is...
Zim paused. Where was he? He looked from side to side, studying each student in the classroom. He narrowed his eyes. The stupid human who’d plagued his existence from his very first day on this Irk-forsaken planet had yet to miss a day of class. He glanced at the clock and back at the door, waiting.
Finally, the large headed boy emerged. Zim smirked gleefully and jotted down:
- The Dib is clearly not capable of dressing himself on Monday mornings.
He opened up a fabric covered Geography book-clearly labeled “DIB” on the inside cover and began to doodle in the pages. He’d forgotten his own useless texts at his base. Thanks to his meticulous notes, however, he discovered The Dib had completed his work and left his book within his locker. Stupid boy.
Dib stopped in front of Zim’s desk, gritting his teeth.
“I knew it was you.” He hissed.
A slow grin spread over Zim’s features. “Whatever are you talking about? Zim has yet to do anything wrong.” He drew a vulgar looking mark in the middle of the “D” on Dib’s name.
“Give me back my textbooks, you ugly space monster.” He seemed to angrily ponder, taking out the water bottle he’d had in the bottom of his backpack for months but forgotten about because of the endless stream of oversized bound stacks of paper, unscrewing the cap with menacingly slow motions.
Zim felt his mouth go dry, but kept his composure. He lifted a few pages of the book and curled his clawed fingers around their edges. “Try it and I rip it down the center.” Surely the textbook was important enough to a human concerned with his education. He felt a small bead of sweet scented sweat sliding down the back of his neck.
“Zim…” Dib recapped the bottle and sighed.
“Can you maybe not do this today? I don’t care about tomorrow, just… Today hasn’t been that great.” He bit the inside of his lip and let his glasses slide down his nose so the frames hid his eyes.
“I propose a truce. Just for today.” He offered, back stiffening.
Zim’s stomach tightened as he stared straight at the stupid worm. His mouth felt dryer for reasons he didn’t understand-after all, the watery threat was already gone!
“A truce,” he repeated, looking bored. “And why do you think I wouldn’t take advantage of an,” he lifted his hands and made quotations with his fingers, “‘off day’ to destroy you?”
He laid his head on his hand and looked at his pencil as he fiddled. He made sure not to look at the Dib. “What would Zim gain from such an offer?”
Dib opened his mouth, letting out a defeated sigh.
“After school, you can tell me to do one thing. I’ll give you information, or let you have one of my weapons. I won’t let you kill me or anything, but… that would help you, right? Like… a free pass coupon. I don’t fucking know, Zim! Just leave me alone for once, shit!” Dib’s voice had slowly grown in volume as he spoke, and the teen was being stared at by his fellow human classmates
“And give me back my textbooks…” He muttered under his breath.
Zim stayed quiet for a solid 45 seconds before finally answering Dib, “my textbooks are at my base.”
He looked at the book and back up at Dib, “Zim is not going to get another detention.” He kicked his feet casually and wet his zipper-like teeth with his tongue. “A free pass, though...to do one thing. This is a fascinating offer.” Zim looked up at Dib, false pupils dilated with the excitement of one-upping his nemesis. He’d yet to properly answer, but it was clear he was considering the idea.
“One question, then.” Dib offered.
“You can ask me one question, and I’m required by, uh…” The human pondered for a moment, “...my truth control nerve to answer it honestly. Does that ‘appease the great and powerful Zim’?” He rolled his eyes and didn’t sound at all serious when he spoke.
“One question and Zim gets to use the books,” he narrowed his eyes. Zim stretched and spoke before Dib could answer, “but...yes. A truce in exchange will be...adequate, I suppose.” It was interesting to find that humans also had a truth control nerve! He quickly wrote it down in the borders of his page along with a darkened note:
- Today there will be no harming of the Dib child.
“There.” He showed Dib the page, “It’s even written down.” Zim set the notebook down and pondered. After quickly adding Dib’s part of the agreement, he thrust the pencil towards Dib, “Sign it!”
Dib bit his lip, his teeth catching a bit of chapped skin as he did, taking the pencil and sighing.
“I get my textbooks back tomorrow, unharmed.” He added it to his part of the agreement and signed. Detention wasn’t all that bad.
Zim nodded, “Yes, yes, fine. Your books shall be unharmed.” He scribbled his own name down hastily.
“Where do you want to meet up so you can ask your probably stupid question?” Dib huffed.
“There has never been a stupid question to pass these lips in all my existence,” Zim told Dib sincerely. It was amazing how unironically he said it. “Your house,” he practically choked on the words, “will do well enough.”
Dib gave a tired smile and went to his seat, a silent acceptance of the alien’s terms.
--
Dib decided it would probably be easier to walk the mile to his home. It was a nice day for the usually dreary area they lived in, Dib waiting outside the school for Zim because he was sure his nemesis would get lost on the way, and he wanted to spend his evening looking over the security footage from the building down the street from Zim’s house to observe any suspicious activity that could be seen from a block away.
The human pulled the collar of his long coat up, blocking the biting breeze from reaching his ears, shuddering and tucking his hands into his pockets. He was almost excited to hear Zim’s question, sure it would lead to nothing more than another failed plan at world domination.
Zim grumbled angrily to himself, shoving hands into the pockets of his jacket as he stepped out of the building. Regardless of having the textbooks, he’d still argued hard enough with his chemistry teacher to earn a week’s worth of detentions.
He stopped in the middle of walking down the front steps, foot midway in the air. He stared at Dib incredulously before opening his mouth, “What are you doing?! Are you waiting to ambush Zim!? HMMM??” Zim snarled at him before continuing on, “This is by far the worst attempt you’ve had at hiding yourse-” He thought to himself as his words tumbled from his lips automatically. Wait. The Dib was here for a reason.
Oh.
Right.
Zim straightened up. “Yes, to your house.” He looked at him calmly as though he’d never freaked out.
Dib rolled his eyes, dragging his thumb nail across the ridges of a loose dime he’d discovered in his pocket.
“You can probably ask while we walk, and I won’t have to listen to your sandpaper voice any longer than I absolutely need to.” He grumbled unhappily, turning towards the street he lived on and walking forward.
“So? What was your question? Or did you even bother to think of one?”
Zim rocked his head from side to side. He’d been debating on a series of questions throughout the day, but none seemed to work. Most of them he could discover through other means without using the precious chance at Dib’s truth-telling nerve. “Of course Zim thought of one!” he snapped.
Absently, Zim drummed his fingers against his chin as they walked. He sucked on a gloved claw and nipped it before returning it to his chin. “...Zim is only allowed one question, yes?” He waited for Dib’s confirmation before continuing, “If you are unable to answer the question, there should be a new question allowed, or further exploration or explanation as to why you cannot.”
“Fine.” Dib agreed, sighing again. He could smell imminent rain in the air, but the skies were clear, Dib choosing not to think too much of it. He didn’t mind rain; it was his planet’s defence against the Irken race.
“You want me to suggest some questions? Since you’re apparently too incompetent to think of anything on your own? Come on, now, Invader. You have all of the knowledge of the human race at your disposal; my dad is the smartest man on the planet, you know.” A chilly breeze began to pick up, increasing the sweet scent of precipitation.
Zim paused and scowled at the quickly rolling clouds. “...I will ask inside.” He ducked his head and pulled up his hood all in one motion. “Hurry up, Dib-Worm. Daylight’s wasting.”
Dib walked up the steps to his house, unlocking the front door when he jiggled the handle but it didn’t give way, wondering idly where Gaz was but knowing she could handle herself without the help of her bothersome older brother.
“This better not be a plot to infiltrate my house. All of my dad’s pertinent research is at his lab.” He warned, leaving the door open and dropping his book bag next to the coat rack. He let out yet another tired sigh and peeled away his coat, scowling at the blank blue and visible stitching of his shirt.
Zim hurried into the door just as the first few raindrops hit the sidewalk. “Zim is here for the question. I honor my truces.” He looked at him suspiciously, “this had better not be a trap.”
“Nobody even told me…” He muttered to himself, tempted to change into his pajamas, having almost forgotten the alien entirely for a moment.
Zim tilted his head and looked up at Dib through his false lenses. “What are you going on about, now??”
“Nothing.” Dib said quickly, dropping onto the couch and kicking off his shoes. He looked over at Zim, then out of the nearby window.
“Well… I guess you’re stuck here until the rain stops. Go ahead and ask your question.”
Zim sighed and slammed the door shut. He balanced himself on the end of the couch and stared at Dib. “You had better answer this.”
He glanced around and tugged off his itchy wig, tossing it onto the coffee table. As he scratched at his antenna, he stared Dib down, making sure he understood how important the question was. “Humans seem to do a ridiculous amount of mating without the reason to reproduce. So, tell Zim, what does sex feel like? ”
Dib was taken aback. He opened and closed his suddenly sticky-dry mouth a few times, squinting up at Zim as though he’d grown a second head. After a moment of deliberation, Dib realized there really was no harm in answering him; from what he knew, Irkens had no need for sex, and Zim probably hadn’t experienced the blind fumblings of seven minutes in heaven he had when he was younger, hot breath and embarrassing noises. He turned bright pink at the thought.
“Awesome.” He admitted.
“Like… your- well, my- uh…” He swallowed, clearing his throat louder than he’d intended and looking away.
“Like your body’s on fire, and… Uh… like you’re about to explode, but in a good way.” He grunted in an angry way.
“You can’t really describe it without experiencing it.”
Zim tugged out his contacts as he listened. His red eyes were dilated with curiosity. “...You cannot explain it further?” He flopped onto the cushion by Dib’s leg and stared at him. He frowned.
“Just explain it better. I don’t like that answer. It needs more details.”
Dib scooted away from the alien, finding himself backed against the far armrest. He had the chance to examine Zim properly for the first time in quite a while, his Adam’s Apple bobbing as he nervously attempted to swallow the growing lump in his throat.
“Well, sex for humans is… Do you know how it works? A penis and a vagina, all that… fun stuff. And it… makes us really happy, I guess. There’s really no way to explain it if you’ve never done it.” He caught himself wondering how a species that looked almost like a plush bug could be such fierce interstellar conquerors. Zim was more adorable than he was frightening. Dib’s gaze locked on his large magenta eyes.
Zim crawled closer, determined not to let Dib get out of answering him properly. Narrowing his eyes, he looked at Dib’s face, “have you never done it? Because you’re not explaining it well at all.” His eyes weren’t mocking or teasing at the fact Dib was a virgin, but rather angry. It was disappointing to find that the one question that had been taunting him would still go unanswered.
“Find a way to explain it!! And tell Zim this!” The small alien thrust a finger towards Dib’s face, “How come males mate with other males or females and females!! Huh?! There is no point! Answer the question better!” He was already throwing a bit of a fit. The rain had trapped him here, and now he was stuck with someone who was completely stupid on the subject of sex.
Dib grit his back teeth so hard his jaw ached, tempted to backhand Zim off of the couch but remembering their truce. He considered, though his mind was lost in the thud of his heart, even louder than the pattering rain outside.
“There’s no words for it, Zim!” He barked.
“Let me show you-” He shoved Zim away from him by his chest and stood.
“Not in the living room. The last thing I need is my sister walking in on me with my hand shoved down my pants.” He stomped, halfway between enraged and determined.
Zim hissed at Dib’s hands against his chest, smoothing down his tunic and jacket-having left it on out of sheer laziness. “Fine.” He clenched his small hands into angry fists and stalked after him. “--You’d better take those pants off!! I won’t be able to see anything if you keep them on.” He had no qualms about nudity, it seemed.
Upon entering his room, Dib struggled out of his pants, then his shirt for good measure, plopping onto the bed. He was mortified to find the persistent tingle between his legs had been less innocent than he’d first thought. The human refused to accept the notion that talking about sex with Zim had done anything more than irritate him.
Zim stood in the doorway, antennae perked with fascination. “Has that lump always been there?” he muttered curiously, not entirely caring that he’d been ignored. There was bound to be an explanation coming very soon, regardless. (That, and he was certain interrupting a human’s mating habit could result in grievous injuries).
“Close and lock the door.” Dib ordered, yanking his bedside table drawer open and grabbing a half-empty bottle of lubricant from it.
“This is masturbation.” He informed.
“...uhuh?” Zim nodded blankly as he closed the door. He leaned his back against it and bumped his elbow into the lock. “And that is…?”
“It’s like sex with yourself.” Dib worked his underwear down just enough to reveal his already half-hard arousal, wrapping a lubricant coated hand around it and falling back on the bed.
Zim crept forward towards his bed, needing a closer look.
“Basically…” His breathing was suddenly labored.
and closer...
“Everyone does it at least once a month. I-I get… really pissy if I don’t do it at least once a week…”
and closer…
...until Zim was on the end of the bed, crawling towards the human, neck straining so he could see better. He couldn’t explain why, but his insides were clenching, and he was sure his pupils were entirely blown. “So...it’s just this? Rubbing the ‘penis,’ yes?” He asked after swallowing several times. He gripped the blanket under his claws and flexed his fingers, trying to stay focused.
“I… there’s o-other things…” Dib’s hand worked a bit faster.
“Like-” He breathed in sharply, stopping.
“What smells like strawberry soda?”
Zim’s antennae swivelled around curiously. “...What are you talking about?” he grumbled, “All Zim can smell is…” ...musk. …sweat. ...pheromones. “...human,” he growled out the word angrily, with a trace of something uncharacteristically hungry to his voice.
He shifted uncomfortably, moving forwards as he did. He straddled Dib’s shins as he tried to figure out what was wrong with himself. “Why did you stop?” Zim demanded, trying to stay on task.
Dib sat up, one hand still around his girth, another brushing through his hair. He grinned, biting his lip and considering carefully how to word his thoughts.
“Humans, when they do this… They have to have some sort of stimulus.” He started, voice a bit deeper than it usually was.
“I don’t have a human female at my disposal, so… I guess you’ll have to do. Let me see your weird alien genitalia, Zim, then you can learn all about it.” He recognized, rather distinctly, that Zim was aroused - or whatever their species passed off as arousal, and was wondering if Zim recognized it, or if he was as ignorant of Irken sexuality as he was human.
Zim felt a hot blush invading the entire surface of his face and neck. “WHY WOULD YOU WANT TO LOOK AT ZIM FOR STIMULI?!” He then stopped, face still heated as he thought about it. “Why wouldn’t you, of course?” He seemed to struggle with the idea for a moment, eyes continuously trailing to sneak peeks at Dib’s body.
“Fine. But keep your filthy hands to yourself,” he gave in quickly, the curiosity of the heat pooling between his own legs driving him mad. He continued to straddle Dib’s legs as he unzipped his jacket slowly, unintentionally swaying his hips to try and rid himself of the strange sensation. He dropped it behind him and moved on.
Zim lifted the edge of his tunic until it came over his head and landed on the floor with a soft “whump.” He moved to his knees and pushed down his leggings without another thought. He kicked his boots to the floor, now left in only his gloves and thigh high socks. The thick scent of his nude being permeated the air from a swollen slit between his legs, already dripping with a translucent, pink tinted liquid.
Dib gawked at Zim, eyes wide with shock, chest heaving quickly. He had expected something much, much less appealing to look at - or to smell. Zim smelt good, nothing like the musky, hot smell of his own need, and his mouth was watering more than he would ever admit.
“You sure I can’t touch it?” The human whispered, hand working up and down his own shaft, face bright red and bottom lip all but bleeding from the force his teeth were digging into it.
Zim shuddered, small goosepimples forming over his flesh. He straddled higher on Dib’s legs, now dripping his jelly onto his naked thighs. He glared at him halfheartedly, eyes flicking down towards Dib’s dick again. He licked his lips. “Your hands are surely filthy…”
He glanced down at the area Dib wanted to touch, then looked at him with furious concern. “What have you done to Zim’s slit? It looks all funny.” It felt even stranger. He made a motion to touch it but pulled back, uncertain. “We had a truce,” Zim scowled, “did you poison me??”
Dib let out a strained, breathy laugh, ignoring his arousal in favor of setting a hand on Zim’s hip, another running across the wet opening even though he hadn’t been given permission.
Zim cried out and dropped his torso forwards. He steadied his hands quickly on Dib’s arms and stared up at him, eyes wide in utter shock and embarrassment. He swallowed hard and tried to glare, only managing a very aroused pout.
“This must be your mating ritual. Getting… like this.” He wanted to push further, but he still had a conscience, running the rough pad of his fingertip very gently across the slit, practically wheezing.
Zim sucked in a sharp breath and let it out shakily. His hips and thighs were trembling and suddenly he just wanted to sit on Dib’s hand and keep it trapped there for a good, long while. He gripped Dib’s wrist and whined pathetically, snarling at himself immediately after for the disgustingly weak sound. “Irken...don’t mate, stupid.” He shook his head at the human but stopped, finding he was a bit dizzy.
“I...don’t like it,” he half lied, weary of the new experience, “I’m...it feels like it’s too full in there.” He bit his lip and closed his eyes tightly, trying not to groan. Dib’s fingers were obviously unworthy, but they felt amazing at the moment. Each stroke shot little electric tingles through his slit and squeedly spooch. It was maddening.
Dib breathed shakily and eased his finger past the fold of sticky green skin, leaning down a bit to watch. His digit was met with an alarmingly prominent bulge. He hooked his finger around it, pulling gently.
Zim shouted loudly and moved his hands to Dib’s shoulders, “Ah-ah!” He couldn’t speak as the two pronged, slick member emerged from his slit, stretching the skin.
“Can I put my dick in there? Like, anywhere?” He asked, surprised that he wasn’t repulsed by the strange length he had managed to guide out of Zim.
“Y--You keep that f..filthy...smell good...dick...thing…” Zim tried to form a sentence, failing miserably as he panted. His chest was tickled by the hair on the top of Dib’s head.
“Shit, Zim… That smells so good…” He set the alien on his back, looming suddenly over him. Dib pushed Zim’s legs out of his way, forcing them open and sprawled, and dragged his tongue suddenly up the liberated length, all of his focus on making his nemesis completely melt at his whims.
“What…Dib-thing?” Zim tried to ask as he was laid on the bed. Strong hands pressed on his inner thighs made tears of pleasure spring to his eyes. The intensity increased ten fold when the hot, flat tongue attacked him. “AHH!” Again, he was rendered speechless, only able to thrash his head from side to side while shouting and mewling in over stimulating pleasure. The bishop, his member, squirmed in response to Dib’s touches. One end completely wrapped under his chin while the other firmly pressed on his tongue.
Dib’s eyes widened a bit at the unexpected reaction he’d gotten from the organ, wrapping his lips around the insistent length pressed against his tongue and sucking. It tasted better than it smelled, some combination of sugar and what he imagined cocaine to taste like. His fingers pushed curiously along the space directly below the two members, hoping to find an orifice to violate.
Zim gripped his head hard as the fingers delved into the remaining space of his slit. His chest was heaving and his pak was warning him to start breathing, but he couldn’t entirely do much about it at the moment. He screamed again as Dib’s words vibrated around one of the prongs of his bishop.
“Cn I fkk yru?” Dib said around the length, pushing his head forward but tugging away suddenly when he felt it prod at his uvula. He coughed, pink running from the corner of his mouth to his cheek.
Zim took the moment to gulp down air as his genitals squirmed in protest from the sudden retreat. “I...w..what did you ask?”
“I want to… fuck you.” Dib said, pushing a finger into the space he had found, up to his knuckle. His head was swimming, the human licking the corner of his mouth where he still tasted the slick.
“Does this hurt?”
Zim shook his head fast, opening his mouth to speak but only moaning loudly instead. The prongs of the bishop wrapped firmly around his wrist and tugged his hand closer, making it clear that the alien was enjoying himself.
Dib added another finger and worked the slit before untangling himself from the foreign organ. He brought his fingers to his mouth and sucked the jelly off of them, using his other hand to settle the head of his member at the space he had been working open.
“This is sex, Zim…” He wheezed, using his saliva and jelly-covered hand to help Zim back on him by his hip, breaching his slit and shuddering. It felt better around his dick than it had his fingers; still, the human gave Zim a chance to adjust to the intrusion.
Zim clutched the blankets below him and arched his back, going almost completely silent at the intense fullness in his body. His only sounds were soft whimpers and breathing, but after a minute, he growled. “...t….this better not be all it is. If you just stit...stilt....sit...still like that….I. will. kill. you.”
Dib laughed again, the noise wispy and pitiful. He dragged his hips back, watching as his arousal left the alien’s body covered in pink fluid, and shoved forward again, leaning over Zim and grunting into where his ear should have been.
“You… y-you like this?” He grunted out, every syllable punctuated with a shallow thrust.
Zim forced his eyes open only to close them immediately. “Ah-Yes!” he hissed, tightening his thighs against Dib’s hips. His bishop curled against his own stomach, leaving pools of pink jelly on his green skin. He groaned and tried to push down more against Dib’s teasing thrusts.
“I can’t get you… pregnant, c-can I?”
“no,” he answered airily, then repeated himself, “no?..” Zim shook his head and reached up, scraping his claws against Dib’s chest, “just...do that more!”
Dib shuddered at the dull ache left behind by covered hands, grabbing the tip of one glove with his teeth and pulling it off of the thin fingers. His pace decreased substantially as he tried to aim for the sweet spot he had read about in humans. Although, he was sure -in the back of his mind- that his efforts were probably in vain. The human rolled his hips, slow and hard, the headboard of his bed thumping against the wall.
Regardless of Dib’s futile attempts to find a “sweetspot”, Zim was clearly enjoying himself. He loudly whined and blushed as his glove was stolen away, “Ah-Dib-that’s,” he groaned louder and gripped at his arm again, needing a handhold. The extra stimulation of skin on skin contact made the alien respond louder and faster.
“Zim…” He said, every method leaving his mind as he neared orgasm, the human not caring about the loud thud of the bed frame on that wall or the lewd, wet sound of skin on skin. He wrapped a hand around Zim’s Bishop and leaned on close, attempting a messy, strawberry-flavored kiss.
“Ah-??” Zim opened his mouth against Dib’s, confused as to what was going on. He felt the hot, flat, flavorful tongue attacking his own and his eyes rolled back in their sockets. His bishop squeezed Dib’s wrist again, pushing fingers against the nub between them, making him scream against his lips and tongue.
Dib pushed the pad of his middle finger against the nub, working it in a small circle and breaking the kiss. He moved to Zim’s neck, biting onto the space where it met his slender green shoulder, feeling his dick twitch inside the alien and thrusting erratically as he came, leaving a nasty indent of his teeth as an unconscious sign of ownership. He rocked slowly, hand moving quickly against the nub to try and bring the alien to the brink after him.
Zim clutched at Dib’s hair, tugging bits out by the roots as his feet thrashed at the bed and Dib’s legs, leaving claw marks down his thighs. He finally figured out to press his heels into the bedding and thrust up into Dib’s touches just as the human filled him with something so very hot. He bit at his own lip as pleasure overtook everything, from Dib’s bite to his firm, fast touches all over his newly discovered “cock.” “MMH!!” He bit his lips hard enough to draw blood as he screamed, cumming heavily from both his slit and his bishop, leaving pools and puddles of jelly on his own skin and the bed.
Dib panted heavily, pulling out of the alien, another wave of orgasm washing over him when he watched his spud, mixed with Zim’s slick, trickle out after his flaccid member. He suddenly remembered exactly what had happened, somewhere between proud and horrified, though he was too tired to really be able to tell which one it was.
“I just… fucked you.” Dib found his hand, dripping with pink, making its way to his mouth as he casually licked it off. It still tasted just as nice as before, but his stomach lurched at the thought.
Zim stared up at him in confusion. Why the hell was the human talking right now...it took away from how good…
he…
felt….
“Oh...dear tallests,” he muttered, eyes wide in a very clear ‘oh shit’ expression. “...I’m going to be executed for this for sure…Whelp...that’s it. Better do it again before they track me down and end my aMAZing existence.” Zim waited a moment then frowned at Dib, “Make with the making.”
Dib blinked at Zim, then fell onto his side, not having taken him seriously.
“I need time to recover. I’ll be able to do it again tomorrow, after a good night’s rest.” He reasoned with a yawn. He couldn’t remember ever having such a strong release, or ever feeling so utterly at peace.
Zim whined in protest and smacked a fist lazily against Dib’s chest, “A whole day?? That’s too long!” He groaned and just went limp, settling his head against Dib’s chest. His antennae tickled against his neck, but he definitely wouldn’t admit how comfortable this was.
“Why are they going to kill you?”
“mm?” Zim glanced up at him. With an impatient sigh, he answered, “Irken do not mate Dib. It’s forbidden…….I didn’t even realize that...anything could even work in that manner.”
"How would they know of you had? And why would they come all the way out here just to kill you for breaking a stupid rule? " Dib asked incredulously, playing absently with an antenna.
His eyes fluttered closed, a low, clicking purr vibrating through his neck. “they just...might know?”
"It doesn't work like that. " Dib laughed.
"Zim, I'm seriously about to pass out." He said, pulling the blanket over them both. He closed his eyes, rubbing Zim's shoulder gently before falling asleep, holding tightly to his alien.
