Chapter Text

Somewhere, reality was still glitching at the seams, a handful of variants gathered around. Mark stood there without a mask, he was half-slumped against a broken pillar, bruised, suit torn at the ribs, but not particularly bothered by the others.

A few others were talking loudly and bitterly, he couldn’t bother until one of them caught his attention. “Anyone else feel weird about how easy it is to beat the shit out of yourself?” one of the variants muttered. “... I mean we’re all the same person, and we’ve got nothing else to do except to wait.”

“Yeah,” said another, red and white suit who perked up and crossed his hands. “It’s getting boring, that Angstrom guy said he’ll transfer us back to our world soon.” His voice was softer, brows furrowed.

“I’m gonna miss that universe.” said by the one with his face fully covered.

“What is there to miss? we’ve destroyed everything.” one variant with a mohawk shrugged.

“To think that he was the ‘Original’ version, he was fucking pathetic.” 

“... I didn’t even get my share of the deal, man.” full masked sighed in defeat, slouched on the makeshift seat.

The one without his mask and drops of blood on his cheekbone exhaled through his nose, “ same goes with me.” not to anyone in particular, but the full mask shifted his head to glance at him. “... I miss William.”

A few heads turned, “Shit. Did he not make it in your world?”

Maskless scoffed, his nails digging into his skin. “No, no. He’s fine. He’s probably home.”

“Then… why say it like that?” The full mask arched his brow.

A few others already turned their heads away, uninterested in the conversation. Maskless let his head fall back against the pillar, his voice dropped just a bit, like it came from somewhere a little deeper. “I dunno. I just miss him. We’ve been together for a while and still he gets on my nerves, like, constantly—he ignores me a lot, talks over movies, makes me wash the sheets every time I bleed on them, reorganizes my collection without my permission… but still. I want to hear his dumb laugh again, his voice, his touch, I… miss everything about him.”

“...You’re unbelievable,” one of them mumbled. “Here’s a tip: go to couple’s therapy. And if that doesn’t work, let it go.” 

“yeah, since you want to bitch and moan about your relationship.” Shiesty smirked behind his mask.

Maskless ignored it, staring up at the fractured skylight, eyes unfocused. “I know he’s gonna be mad when I get back, or actually, maybe he won’t, he’ll probably not care about it. He acts all cool but then he guilt-trips me without saying anything. You ever get those texts that are just, ‘K’ or ‘Do what you want’? He does that. And then like three hours later I’m the one on the phone apologizing and begging him.”

A few other Marks exchanged looks. “Your William sounds like a pain in the ass.”

Maskless sighed, rolling his eyes at the Shiesty, a more childish Mark. He paused, then a softer smile and a faint blush appeared as he trailed his thoughts on to whoever was willing to listen to him. “... Both literally and metaphorically, I’d say.” Shiesty let out a low growl. 

“...But he smells really good. He hugs me in his sleep and cuddles even when we’ve fought. And he always waits up for me, sometimes he pretends he doesn’t care but he does. I bet he’s waiting now. He can get a little too possessive sometimes.” Maskless tangled his hands together, looking down at the ground.

Someone snorted, one in yellow and black that thought he wouldn’t care less commented. “Or he's ghosting you out of spite.”

Maskless shrugged, stretching his shoulders. “Yeah. Probably.” he returned back to his original position, a hint of rage quietly building up inside him.

Mark didn’t say much after that.

The others had gone back to bickering and fighting or sulking in their own corners, but he stayed where he was with his arms loosely crossed, eyes half-lidded, like he was replaying something in his head. His ribs ached, hands restless, his shoulder throbbed from the fight, but it was nothing compared to the tight, stupid heat sitting right behind his sternum. 

He turned on his phone, scrolling past the multiple messages that were sent but went unnoticed by his partner. He recalled every moment that William made that pissed him off, the urge to start another fight boils. “That’s it. I’m gonna wreck him when I get back,” he muttered to himself. “... drain him like a succubus.”

The nearest Mark side-eyed him. “Dude.”

Maskless smirked without humor. “What? He deserves it.” He paused for a moment. If he could describe what relationship he and his William had, it’d be complicated. They fight all the time, then make up by sleeping together and act like nothing happened until they fight again about useless things. Fight, fuck, repeat. Maskless furrowed his brows, his William’s been ignoring him so much lately. “He’s been ignoring my texts for the past week—probably mad at me that I didn't say goodbye. I mean, I didn’t know I was gonna get kidnapped and sent here to destroy it.”

No response from the other variant, Maskless lowered his gaze and spoke softly. “He’s gonna pretend like he doesn’t care. Say something dumb like ‘Oh, you’re alive? Cool.’ And then do that fake eye-roll thing that makes me wanna pin him to the wall and—”

The sound of a portal powering up cut him off, the other Mark listening in sighed in relief. Searing green light cracked open the sky, peeling back the layers of dimension with a low, buzzing hum. Levi’s voice echoed across reality, something about time stabilizing and timelines re-merging, they all don’t care about it.

The portal dropped him off just outside their apartment.

His boots hit concrete hard. The sky was dusky and orange, city lights flickering on like fireflies. The world felt familiar but thinner, like stepping into a dream made real again.

Mark didn’t waste time. He tore through the air, heading for William’s window instead of the door like usual. He wanted to surprise him, maybe tackle him onto the couch and bury his face in his neck and breathe.

But when he landed softly on the balcony and peered in, William was sitting on the couch, back straight, phone in hand, and his jaw tight. The curtains were half-drawn. One lamp on. The TV was playing something muted, just background noise. The second Mark knocked gently against the glass—William glanced over and paused. They both stared at each other before William turned back to his phone. Mark blinked dumbfoundedly, he waited and waited longer before he got bored and knocked again.

William finally got up, opened the sliding door just enough with a grunt, and stepped back without saying anything. Mark stepped inside. The air hit him, it felt too cold, or maybe it was just William’s expression. “Hey,” Mark tried as he got inside, almost falling as he climbed in. He smiled. “I’m back.”

“Yeah.” William didn’t look at him. “I can see that.”

A flicker of frustration scratched under Mark’s skin. “Okay… I’m gonna hug you now. Unless you’re gonna punch me first?”

Nothing. Mark hesitated. The ache in his chest twisted. “You’re mad,” he said, more softly. “That I left?” his tone shifted at the end, letting a low growl slip from his tongue.

William scoffed. “Left? You disappeared, Mark. No words. I don’t even care anymore.”

“I didn’t exactly have a choice! It was a dimensional rip, not a vacation, I basically got kidnapped!—”

“But you still didn’t say goodbye.” William sounded sarcastic but it felt a little too genuine to be true. Mark felt the urge to facepalm at the logic behind it, but knowing their relationship, there really wasn't much of a valid reason on why they’re fighting, it’s almost like they both need to release the tension even if they’re not thinking straight, it doesn’t have to make sense. Maybe, just maybe, the reason Mark got attached was because they were both always honest about their feelings when they fight, albeit every word that came out was harsh.

The silence that followed was sharp, Mark clenched his jaw. “You didn’t answer my texts.”

“You only sent three,” William snapped. “And one of them was just ‘u up?’ with a winky face.”

Mark flushed. “Okay, yeah, I could’ve done better, but I was literally fighting versions of myself and dodging brain-hacking tech for days, so maybe cut me some slack here!”

William crossed his arms. Mark stepped closer, his voice edging louder. “I came back. For you .”

“You don’t get to act like the hero just because you showed up again.”

Mark’s temper snapped—fast, hot and loud. “You’re so fucking annoying!”

William raised a brow, unbothered. “Yeah? Good thing I didn’t miss you then.”

The moment he blinked, Mark had already stormed past him, yanked open the bedroom drawer, and pulled out a half-used box of condoms—counted them out onto the bed one by one. “Twelve,” he hissed. “Twelve fucking condoms.”

William leaned on the doorway, unimpressed. “...What are you doing?”

Mark turned, flushed with frustration and something deeper—need, maybe. Shame and lust barely contained, maybe he did get off to this, he couldn’t think straight anymore. “You don’t get to ignore me and then act like I’m overreacting. You’re gonna make it up to me.”

William stared. Mark stared back, defiantly, then he followed his sentence as Will stared. “I’m not forgiving you until every one of these is used. I want you to ruin me until I stop caring, like how you made me cry the first night we spent together.”

Another pause between the two. Then Mark added, a lower, gritted, eyes dark: “I’m going to drain you, every drop of it.”

Chapter Text

Mark stood there, flushed and defiant, arms crossed, the box of condoms on the bed like a dare. “I’m not forgiving you,” he said again, voice shaking slightly now, “until every single one is used.”

William didn’t blink, he didn’t even flinch. He just leaned against the doorway a little more casually, arms folded, one brow raised. His expression was unreadable, like he was calculating something, perhaps figuring out how much damage he could do to him, how long it would take to make Mark fold.

And then he smiled. “Okay.”

Mark’s eyes narrowed, his back stiffened at the sudden agreement. “...Okay?” He set one foot behind him, leaning back one step.

William shrugged, taking a slow step forward. “You want me to fuck the attitude out of you twelve times in a row? I’m not complaining.”

Mark’s throat tightened, heat rushing to his face and flushed. He had expected resistance from him. Sarcasm, maybe a tired eye-roll. But not this—this sudden shift, this calm, centered power radiating off William’s body like he was stepping into a fight he knew he’d win. And then William kept walking. 

Step by step, closing the distance, until Mark backed up instinctively and bumped into the bed’s edge. William reached down to pick up the box, weighing it in one hand. He looked at Mark, eyes softened. “Take your clothes off.”

Mark didn’t move, he gritted his teeth and averted his eyes. Clearly this wasn't going to his original plan, he wanted William to submit but he can't let William take control of him so easily. 

He opened his mouth to say something sharp, probably something like ‘ don’t tell me what to do’ but William’s hand caught his jaw, thumb pressing firmly under his chin. “I said,” William murmured, tone dropping, “take them off.”

Mark swallowed hard. His heart was hammering now, something needy that curled warm in his stomach and made his knees feel a little too light as they buckled. Still, he didn’t go down without a bite. “You’re being kind of an asshole right now,” he muttered.

William’s smile sharpened. “You like it. I know you do.”

Mark flushed, fingers clenched. “I don’t—”

“Bullshit.” William leaned in, lips brushing his ear now, voice all heat and quiet command. “You came in here stomping and bratty because you wanted me to pin you down and take what’s mine.”

Mark’s breath caught. William’s fingers curled under the hem of his shirt and pulled it up slowly, exposing his bruised ribs, his scarred stomach, the flush spreading across his chest. His hands were warm, a little too warm. And he knew it was intentional. “You missed me,” William said, so low it made Mark tremble. “Didn’t you?”

“I—”

“You were gone for days and I could barely sleep. Kept checking the news, watching the sky, thinking maybe I’d see you come crashing down. You don’t think that drove me crazy, too?”

Mark opened his mouth again, but then William’s mouth was on his throat, biting down just hard enough to make him gasp, and his knees almost buckled. “I’m not ignoring you anymore,” William murmured. “I’m claiming you.”

Mark's breath hitched. He hated how much his body reacted, how he liked that word. Claimed. Like he was a thing, not a person. Like he belonged to someone, that he was special. “...You’re still annoying,” he whispered weakly.

William shoved him gently onto the bed and climbed over him. “I bet you’re going to be begging me to let you rest by number five.”

“I won’t—”

“Shhh.” William’s hand covered his mouth, pressing him down into the mattress. “You will.”

The first condom was already in William’s hand when Mark pulled off the rest of his clothes and crawled onto his lap.

Smug and confident, though William had already had plans to ruin him. Mark straddled William’s thighs, hands braced on his chest, bare skin flushed but posture cocky. His hips rolled just enough to make contact, just enough to tease.

“Keep looking at me like that,” Mark said, chin tilted, “and I might start thinking you actually missed me.”

William didn’t answer right away. He just slid the foil open with clean fingers and slowly rolled it on, watching Mark the entire time. No shame, no rush. Like he had all the time in the world to stare at the boy grinding against him like he had a point to prove. “You really didn't believe me?”

Mark hissed when their bodies aligned, then narrowed his eyes when William didn’t move. “What, are you just gonna sit there and admire me?”

William leaned back against the pillows, hands loose on Mark’s hips. “Kind of hard not to.”

Mark flushed but refused to show it. He lifted his hips and sank down slowly, eyes fluttering for a second before catching himself and biting back the noise that nearly escaped.

He settled fully with a shaky breath, then smirked, lips parted and eyes hazy. “There. Now I’m in charge.”

William tilted his head. “You think riding me makes you the boss?”

Mark rolled his hips again, slow and deliberate, digging his nails into William’s shoulders. “You’re not the one doing the work.”

“Mmm,” William hummed, eyes heavy-lidded, thumbs stroking over the skin of Mark’s waist. “No. I’m just getting a front row seat,” he chuckled “getting the best view and the VIP treatment down here.”

Mark opened his mouth to say something clever, but then William leaned forward, not to take control, he instead pressed his mouth over one of Mark’s nipples. Soft at first, a gentle drag of teeth as he licked his chest.

Mark shivered. His thighs trembled slightly from the contact. He tried to laugh it off. “T-that’s not gonna—”

Then William sucked. Hard. Mark gasped, his own cock twitching against William’s stomach.

The grip he had on power started to falter. “Sensitive,” William murmured, lips brushing over the same spot again. “You’ve been waiting for this.”

“I wasn’t desperate—”

“Sure you weren’t.” William kissed down Mark’s chest, tongue flicking just beneath his ribs. “You weren’t moaning my name into the pillow a few nights ago before you disappeared, right?”

Mark’s breath caught. He jerked his hips in retaliation, but William just tightened his grip, holding him in place. “This is what you wanted, right?” William whispered against his skin. “To ride me and get praised? To feel me watching while you fall apart?”

Mark’s thighs shook again, his body betraying him. He tried to speak, to sass, to deny Will, but all he managed was a shaky, “S-shut up.”

William smiled, slow and dangerous. “No. I think I’ll keep talking.” He brushed a hand up Mark’s spine, slow and warm, then grabbed his hair at the nape of his neck and gently pulled just enough to tip his head back.

Mark groaned and kept moving, fucking himself down harder now, lips parted, face burning with how badly he wanted William to keep watching . “You’re so fucking pretty like this,” William said, almost too softly. “All attitude, but your body’s begging for me.”

Mark’s thighs twitched again, and he swore under his breath. William’s voice dropped further, warm, and reverent. “Take what you need, baby. I’ll be right here.”

That broke something in Mark, his rhythm faltering, his breath catching and his cock leaking pre come against their skin with each thrust. The smugness in his expression was fracturing, giving way to flushed desperation.

But he still said, with a breathless voice “One. That’s one down. You’ve got eleven more to go.” Mark gasped, his eyes trailed down to his crotch and whined as William slowed down, taking no chances of making Mark come undone. Mark’s jaw clenched, his own hand slowly stroking his cock covered in the thin latex material.

William’s hands slipped down to cup his ass, thumbs spreading him wider, and he looked up at Mark with a small, dark smile.

“I hope you mean that.”

Chapter Text

Mark barely had time to catch his breath before William was reaching for the second condom—cool fingers brushing over his thigh as he peeled the wrapper open, slow as sin.

“You good?” William asked, voice even, but eyes dark with something more than concern.

Mark was still in his lap, thighs quivering slightly, a tremor running up his spine with every small shift of friction. His face was flushed, lips parted, breath uneven.

“I’m—” Mark paused to swallow. “I’m fine.”

William tilted his head. “Sure?”

Mark tried to roll his hips again, prove a point but the moment he felt the raw stretch of overused nerves, his gasp betrayed him. He clenched around nothing, already missing the heat, and his knees nearly buckled under him despite being on top.

“Y-you’re wasting time,” he spat, trying to mask the shake in his voice. “I said twelve.”

William gave him a look like he was indulging him.

“You’re barely holding yourself up.”

“Am not.”

William leaned in close again, lips brushing the shell of Mark’s ear as he rolled the condom onto himself. “You’ll beg me to take over before we reach five.”

“I won’t—”

Then William gripped his hips hard, lifted him slightly, and pushed up into him in one smooth, brutal motion.

Mark cried out, high-pitched and broken. His entire body jolting as he collapsed forward against William’s chest. The sudden stretch hit too deep, too fast, and his cock twitched helplessly between them, leaking against William’s stomach.

“Fuck—fuck you—” he whispered, voice tight.

William didn’t answer. He just held Mark in place, letting him feel every inch buried to the hilt, motionless claiming. Mark clawed at his shoulders now, trying to find some rhythm again, some way to get control back.

William moved first. A hard thrust up that landed deep, sharp and measured. Mark yelped. His back arched, mouth open in a silent moan, his thighs threatening to give out. “Wha—wait, wait—”

“You’re doing so good,” William murmured against his neck. “You want more?”

“I didn’t—I’m supposed to be—”

“Shhh.” William kissed the corner of his jaw. “You are. You’re being so good for me.”

That praise ruined him more than the thrust did. Mark trembled, eyes glassy now, body jerking every time William bucked his hips. He tried to brace his hands against William’s chest, but they slipped. He was too warm, too sensitive, and William kept hitting that spot that made his knees collapse.

“F-fuck, slow down—”

“You said twelve,” William whispered, licking down the curve of Mark’s throat. “I’m just helping.”

“Th-that’s not—” Mark whimpered when William rolled his hips again, just right. “Fuck—please—”

He didn’t even know what he was begging for anymore. More? Less? A break? Didn’t matter. William heard it, he smirked when he was basked in the sight. 

Mark was shaking now—his rhythm gone, his attitude unraveling with every thrust. His voice cracked, eyes fluttering shut.

And William, still in control, leaned in and murmured, “That’s two.”

Mark was already glassy-eyed when William flipped him. One smooth, practiced shift of weight with a curl of arms under thighs. A press of lips to the base of his throat, then Mark was on his back with his legs spread open, ankles hooked over William’s shoulders, blinking up in stunned silence.

And then William slid in again, deeper and deliberate. Mark shuddered, back arching off the bed with a bitten-off cry.

“Look at you,” William murmured, watching the way Mark’s expression twisted, caught between fury and euphoria. “All that power, all that attitude—and you’re begging for it like a fucking toy.”

Mark grit his teeth. “I’m not—f-fuck you—”

William agreed, smirking. “Your body’s giving you away.” He pulled out almost all the way and slammed back in—hard.

Mark screamed into his forearm, the mattress creaking beneath him. William’s voice was soft, cruel. 

“Shut the fuck—ah—shut up—!”

William didn’t. He leaned down slightly, hips grinding in deep, hitting that spot over and over until Mark’s brain short-circuited and his voice cracked around a moan he couldn’t swallow.

“Thought you’d be tougher,” William whispered against his ear. “Thought you could handle it.”

Mark lashed out, breathless. “You think this is good? You’re—fuck—you’re barely average.”

“Oh yeah?” William’s fingers wrapped around Mark’s cock covered in thin rubber, stroking him in time with the next brutal thrust. “You’re dripping like you disagree.”

“N-no—ahh fu—ck!”

William laughed—actually laughed, breath hot against Mark’s cheek. “You’re shaking.”

“B-because I’m pissed,” Mark lied, voice cracking, eyes glassy. “Because your dick game’s trash.”

William shifted his angle just slightly and Mark saw stars. His entire body tensed, a full-body clench, mouth falling open with a noise that could only be described as a sob.

“F-fuck you—” he whined again, but there was no bite to his voice anymore. The helpless, slurred tail-end of pride drowning in pleasure.

William held him there, one hand braced beside his head, the other still stroking him—slow now, teasing, cruel.

“Can’t even lie right,” he murmured. “You’ve been clenching around me like you’re trying to keep me inside forever.”

Mark grit his teeth, his eyes fluttering, breath hitching, so close and furious about it. “I’ve had better,” he growled weakly, jaw tight.

William just smiled. “Then come and pretend I’m one of them.”

Mark jerked up into William’s hand with a loud, broken noise, his body wracked with shudders as he came—hot and fast, helpless, cock twitching between them while his mouth hung open in a ruined moan.

William kept fucking him through it. Kept talking, kept mocking.

“That's three,” he said lowly, voice brushing over Mark’s ear like a threat. “And I’m still hard.”

Mark blinked up at the ceiling, dazed, lips parted, already overstimulated and still trying to scowl through it. “Gonna... regret this,” he slurred.

William kissed the sweat off his temple. “No,” he whispered. “You are.”

Mark hadn’t stopped twitching since the third orgasm ripped through him.

He was still shaking, his legs splayed, flushed and ruined, his chest rising and falling with ragged, shallow breaths. His cock was limp now, spent, twitching against his stomach with every slow grind of William’s hips.

William didn’t need to rush. He had time. And more importantly, Mark had said twelve, counting that both he and Mark wore the condoms.

That meant William had less than eight chances to watch him break.

Round four began without ceremony.

A fresh pair of condoms. A soft, wet noise as William pushed back inside and he pumped Mark's flaccid cock to place the condom. Mark gasped—a sharp, strangled sound and tried to squirm, but William held his hips firm. “No—fuck, fuck—wait—!”

“You said you wouldn’t forgive me,” William murmured, slow and low, “until all twelve were used.”

“I was angry!” Mark gasped, gripping the sheets.

William leaned in, dragging his teeth across Mark’s collarbone. “And now?”

Mark moaned, whined, really—his hips jerking up even as his legs trembled violently. His voice cracked on the next word. “... Still angry.”

William laughed softly and fucked into him just a bit harder. Mark's fingers twisted in the sheets, legs trying and failing to close around William’s hips. He was too raw, too sensitive, every nerve screaming but it wasn’t enough to make him stop. “You’re crying,” William murmured. “Do you want me to stop?”

Mark’s eyes were glassy, lashes wet. He turned his head away. “No.”

“You sure?”

“Don’t—fucking—ask me that,” Mark growled, voice hoarse. “Just do it. You’re not gonna break me, you smug—ah—fuck!”

Another hard thrust. Another quake through his thighs. “You’re leaking again,” William whispered, brushing his thumb through the mess smeared across Mark’s stomach.

Mark made a sound like a whimper strangled into a growl. “I’m gonna break your dick,” he hissed, throat raw.

William smiled, eyes locking on to him, gently and mockingly. 

“D-don’t flatter yourself—ahhh—fucking—c-can’t even last—like a virgin,” Mark stammered, trying to be harsh, but his body gave it all away.

William leaned down, hand slipping under his thigh to press him open more. “You think I’m trying to last?” he whispered. “I’m trying to keep you full.”

Mark choked on his own saliva. His hands on William’s arms, clutching tight now, no longer pushing it. “I hate you,” he whispered. “H-hate you so fucking much—”

“I know.” Another sharp thrust. “Say it again while you come.”

“I won’t—”

And he did anyway. "I h-hate you, Will." Mark came untouched, body's reacting to him. 

Somewhere between the steady, brutal rhythm of William’s hips and the slow, loving grip on his throat, Mark's body felt shattered, again. Without touching his cock not asking and just the overwhelming sensation of being held down and known.

His body seized—another orgasm spilling out of him with a sob that he bit into his own hand.

William didn’t let up. He kept moving, slower now, smoother, stroking Mark’s thighs as he murmured praises through his teeth. “That’s four.”

Mark couldn’t speak. He choked, letting out a wrecked noise—no longer sure if he wanted to run or cry or kiss him. William bent down, kissed his temple, and asked gently: “Still mad?”

Mark, eyes unfocused, whispered—“…yes.”

William smiled at him. “Good.”
