#invincible comic

I was cleaning my inbox n accidentally deleted the ask 💔

“You won’t believe what just happened, oh man!” Mark exclaimed with glee; an unfamiliar look of pride swam within his irises. It was the night he received his powers; a deep crater buried itself into your driveway from his failed landing. “What?” you questioned, prying your front door open as he entered. There were scuff marks littered across his naked upper body, battered and bruised from his knightly adventure. “It was incredible. I—I flew,” he explained, his hand gesturing excitedly. This was a dream of his; he would craft makeshift suits and detail desired escapades to save the world. However, for it to come true was another story.

“No way! This… this is a funny joke,” you sputtered. One doesn’t usually acquire powers at random, but in this dimension, who knows? “No, really. I took a huge leap off my roof, not really expecting anything,” he interrupted to soften the already ridiculous landing of his story. “You know, and I just took off.” The topic was so exhilarating; the thought of questioning him hadn’t dawned upon you. He leaned against the back of your couch, crossing his arms as you two reminisced.

“Wait—why were you jumping from the roof anyway? What if nothing happened and you fell?” you questioned with a raised brow. “I know, I know, it’s stupid. But I was curious and decided to give it a try,” he rationalized quietly, fingers nervously scratching his nape. “Aw… I want powers now,” you feigned sadness as you sulked. It was your attempt at being amusing, but truthfully, you felt left behind. Was it envy? Was it the need to feel important? Was it the fear of him leaving you behind to begin his journey as a hero? You didn’t know at the time. His expression became tinged slightly with guilt. “Hey, don’t worry, I’m sure you’ll get powers soon,” he reassured you, but it was too humorous to be sincere.

“Yeah… soon. Real funny, wasn’t it?” you said to yourself as your body perched against a rooftop. It was the second day of the Mark variants ravaging Earth like their playground. The once-majestic towers now stand as skeletal frames, their glass windows shattered. Debris litters the streets, a tragic mix of shattered concrete and twisted metal, and the air hangs heavy with the scent of smoke and ash. Heroes formed makeshift shelters and sifted through rubble for survivors.

The Mark you once knew was head over heels for Atom Eve. It was no secret; he was a lost puppy whose ears would perk at the sound of his name on her tongue. Utterly devoted. Sickeningly in love. You were the very last to discern his truth. The two were written in stone, but it left a bitter taste in your mouth that you had long since gotten over. Until now. You were late to the news of the world's destruction. A strangely familiar face appeared on the news, a version of Mark that made your chest tighten. Within your family, a strange ability was acquired—a power bred through evolution to ensure survival in a world full of the unknown. Once in a lifetime, through a series of visions, you would discover a pivotal moment in time to peer through. That moment was now. Eighteen variants were loose internationally, each with their own tragic story and love interests. Six had dated or lost their Atom Eve, five had slain their worlds' Amber, and six had been devoted to you.

Helping where you could, you began assisting in fighting off the weaklings who figured now was the best time to attack Earth. Micro tears riddled your uniform as you tore through them mercilessly, all through a look of pity. There were days you'd resent this “job” you'd granted yourself, the little recognition and appreciation you'd receive from the public. How selfish of them—and you. You wanted an excuse to have this world fair alone without a need to rebel when no one would notice. As luck would have it, a voice suddenly dawned behind you, his body floating midair and adorned with the appearance of your dearest friend.

Mohawk Mark

“Oh, shit… I know you,” he rasped, his expression twisted into a cocky grin. His stature and pose were that of confidence—and a man who caused insurmountable damage to those he met. “You look just like her,” he continued, his feet finding purchase on the ground as his stride increased. “Sorry, you've got the wrong one—try finding her—” Just as you spoke, static buzzed in your skull—a low crackling hum that drowned out the edges of the memory before it fully formed. It was there—just beyond reach—shrouded in white noise.

The harder you focused, the more the static swelled, but for a moment, the interference cleared. A voice—the ghost of a feeling—and just as quickly, it was swallowed again. You understood the gist; he was indeed one you would find yourself tangled with. “Looks like you’ve been through some tough shit—mind if I join you?” Without waiting for a response, he lunged forward, grappling you in a powerful embrace. His intent wasn't one of danger but instead of safekeeping despite his demeanor. Reflexes took over as you slammed against his cranium with the strength you could muster, effectively knocking him back.

"Fuck, you're a feisty one," Mohawk Mark growled, his breath hot against your ear. "I like that shit. Let's see how you handle this." His chuckle was condescending—yet a thrill shot through you. “‘Won't be handling shit,” you quipped before biting into his neck—just rigid enough to draw blood. He groaned, his flight knocking you two back into an alleyway.

Similarly to your Mark, he seemed attracted to strength, his veins pumping with lust rather than adrenaline. Holding a firm grasp of your jaw, his lips collided with yours in a searing and blood-stained kiss. The muscle of his tongue forcefully parted your lips as he sought to taste you against his own. Finding yourself against the wall, your legs wrapped around the width of his waist, your ass snugly hovering over his pelvis.

He pulled away every few seconds to watch your expression succumb to your selfish wants. Sex with the enemy was enticing and you weren’t letting him escape any time soon. “You planned this?” you murmured between the saliva-ridden kisses. “That would be telling. You know enough if you’re agreeing to this.” His voice grew to tease as he licked his lips—mirroring his satisfaction before peppering kisses down your exposed neck.

His version of sex was rough, with small increments of romance—only reserved for the best prize. With muffled groans, his teeth harshly nipped their way lower, his fingers tearing through the fabric of your suit. As he continued down your now-exposed cleavage, his tongue ran along the scantily clad lace of your bra. Staring up at you, he let out a mischievous snicker before his teeth snagged the cup and tore it from your chest—leaving it discarded on the ground.

“Shit… was fucking not enough? Had to ruin my clothes too,” you complained as your hips bucked against his pointedly. This earned a guttural grunt from the flesh of your breasts, as he heaved out a response. “You’ll forget about them anyway,” he dismissed as he continued until your panties were the last to be removed. The cool air dusted your wet cunt—its arousal seeping through your folds like honey. Its chill made you shiver and like bees to nectar, his tongue feasted before his eyes.

Hoisting you up, your thighs rested against his shoulders as he knelt, the angle allowing his tongue to slip inside your already spasming pussy. An unusual pink hue dusted his cheek as he stared up at you in utter bliss. Your fingers dug into his forearms, your puffy folds pressed against his lips as he devoured you. With your head resting against the wall, your hips ground themselves relentlessly against his tongue.

"Mmm, shit, already soaking wet for me," he taunted, pumping his tongue in and out of your tight cunt. His tongue—rough and textured—lashed out to lap at your clit, sending jolts of pleasure through your body. His groans sent mild vibrations through you as his fingers reached up to paw at your tits, nipples stiffened in the cold air. You couldn't help but moan as he ate you out with relentless intensity, his tongue plunging deep into your folds. His calloused hands roamed your exposed flesh, pinching and kneading your breasts, twisting your sensitive nipples until they grew numb.

His hands couldn't stop their exploration—they explored what he had lost many years ago. Sparks flew as his tongue circled against your clit, flickering the bundle of nerves with a speed inexperienced before. Every time you neared the precipice of your orgasm, his tongue would flatten as he sucked your clit—ruining the rhythm. You tugged his hair with a frustrated groan, and his eyes rolled into his skull with an amused moan.

Finally pulling away, he stood to his feet. His lips parted to speak when suddenly, “Hurry the fuck up,” you said curtly with exasperated gasps. With lidded eyes, a Cheshire grin settled across his features. “Yes, ma’am.” Prying his suit off, he palmed his dampening erection. For once he fell silent as anticipation ate away at you both. As he freed his cock from the confinement of his boxers, it slapped against his lower abdomen.

It stood with a veiny girth—the tip kissed a rosy red like his many mistresses' lipsticks. With a pleased hiss, he stroked himself briefly—eyes just barely losing focus from the buildup before he plunged himself into you. Your pussy hugged him with a familiarity that felt like home, the painful stretch soon becoming one of bliss. His hips began to quicken, wanting to see your fucked-out expression like never before.

However, his greed overwhelmed him as the stimulation grew difficult to ignore. His usual grunts and growls diluted into groans and profanities. The alleyway echoed with the cacophony of moans that mingled in the air—inharmonious, yet emotion-filled as a flame flickered within your core. “I’ve waited so fucking long for this,” he grunted, a grin etched into his lips. “N-None of them—no ssslut compares to this. Only pussy I need—only woman I want.” A groan interrupted his sentence as your cunt contracted around him—swallowing him at the base.

That’s right—every harem formed and woman fucked was so he could ruin the image of you that plagued his mind in its grief. The vulnerability of it all made your toes curl, even if it wasn't much.

The fingers pawing at your breasts began kneading them like stress balls, until they were red. Truthfully, he missed every inch of you—not that he would admit that, especially since you weren’t exactly his. A high-pitched moan ripped from your throat as he continued to bounce you on his dick. Pre-cum coated your insides as the sounds of arousal grew louder, his balls tightening. With every thrust, he could see the air physically leave you, the scuff marks from brick marking your skin.

He could barely tell where to focus his eyes—on your tits or face? Both were gorgeous but fuck, he should just kidnap you and take you home with him, right? “Fuuuuck, Mark… I’m g-go—” you groaned as your fingernails indented into his skin, a pain and pleasure-filled gasp crawling from his throat. “Fuck, yeah…” he said, his raspy voice cracking with the slightest whine. “Take it… s-shit, take it…!” It was a growl as his eyes fluttered shut to hide his eyes practically rolling around his skull. With a clenched jaw, his dick began to milk itself. The pleasure mounted as your impending orgasm washed your body in a sweat-breaking heat. Just as he came, your cunt spasmed, once he pulled out, something within snapped as an aroused gush squirted from you.

His groin was now coated in your scent, taste, and the result of your rough fucking. The pleasure racked your brain as tears threatened to spill over. Noticing this—and pleased with his efforts—he let out a short chortle, a hand coming up to swipe your folds and have a final taste. His expression turned into a feigned sob as he silently teased—his tip running a line between your folds and ass, resisting the temptation to fill your asshole with his seed. Once you two were settled from your high, he spoke up. “Had fun, babe.” Your eyebrow lifted at the newly coined pet name.

Suddenly, a muffled voice in his ear caught his attention. “Shit…” he muttered with an annoyed grimace at Angstrom ruining his amusement. “Go on,” you beckoned. “Not yours anyway—so no need to stick around.” It was a light jab—one he received with a satisfied smirk before taking flight. “Doesn’t matter—I’ll be back,” he replied curtly before disappearing into the horizon.

You stood there—naked—processing what just happened. "Shit, I need a new suit from my apartment.”

Variant #17 Mark (I wouldn't even keep you as a slave in my Empire!) Or Sinister Mark (personalities are similar in the comics, so imagine what you will.)

"You thought you could hide from me?" he said, peering down at you with a friendly grin for someone so domineering. Staring down at the man’s shadow, his cape billowed in the wind. Unlike the other Marks you’d caught a glimpse of, this one barely had a bruise on him. “I’ve been looking everywhere for you,” he finished before he landed softly on the ground. As he approached, you remained still, eyebrows creasing into a frown. “I’m not—” You were abruptly cut off by a low voice as his head tilted to stare into your eyes. “Don’t play stupid. My version of you had the same power—but she resisted our cause.” His voice was tinged with pity as he frowned; he decided to take another route in his approach.

“I’ll tell you what—I’ll leave if you come with me,” he offered with an outstretched palm. You vehemently shook your head in disagreement. “I’m not going—it'll disrupt the timeline.”

“Why does that matter?” he asked.

“What makes you think I won't resist either…?” you retorted, causing his eyebrows to raise slightly in thought. “I’ll change your mind—and give you what you missed out on in my world.” It was such a matter-of-fact opinion—one rooted in a determination to outclass any obstacle that might deter him. Curiosity bested you the moment you turned to face the chaos erupting in the streets as a strong gust of wind obscured the debris. He was behind you. His fingers draped over your waist as he took flight—and to… your apartment? “I’ve been watching you for a while now… I know all about your preferences. Let’s have some fun, shall we?” His lips just barely grazed your ear.

Amongst the hands that roamed your body, a sense of longing lingered in every squeeze and grope. While being one of the strongest—and surely the most vile—his personality could be charming like your dimension’s Mark. Even if feigned for manipulation. He spun you around to face him, that polite smile etched into his face again as his body betrayed innocence. The erection forming within his costume became difficult to ignore—but he found a distraction. A touch, a handhold, and finally—a kiss.

“Let me show you what it's truly like to be satisfied.” His words were reassuring, yet they felt more directed toward his version of you rather than now. His tongue swept into your mouth, tangling itself in a wet heat as he sucked the air from your lungs. The warmth of his fingers spread across your cheek as his tongue attempted to delve impossibly deep. The taste was better than you imagined—not that you expected any less. If anything, finding him in a forgiving mood proved to be favorable.

His fingers shifted from your face to the back of your costume—in his attempt to be gentle, he tore the cloth from your body like tissue paper. In an instant, his costume was discarded in the corner, leaving him in snug boxers that hugged his dick. Before you knew it, you were pinned against the bed—a hand flush against your throat as he shrugged slightly. “Didn’t mean for that to happen,” he said, an amused huff exiting his nose as you exchanged knowing glances.

The remaining hand gently pried the panties from around your hips and down the length of your legs. His eyes fell upon the wet patch that seeped through the thin fabric—as the semblance of a pleased grin stretched across his lips. Focusing his attention once more, his fingers slowly parted your folds, watching as your velvety walls peeked through the slit. Its warm flesh was inviting—something he had yet to try since you retaliated so often against him at home. Just why couldn’t you be this welcoming? So willing to be corrupted? So… morally gray at the least.

Pressing two digits inside your warmth, he watched it conform to the size of his fingers. An obvious shiver ran through him with each moan that vibrated from your throat—as he imagined you hugging him and wrapped around his cock in plea. The sensations set your skin alight with gooseflesh—and each time you attempted to scurry away from his gift, the hold around your neck tightened ever so slightly. He was such a brat.

Your hips ground into his hand, clit colliding with his palm in gentle waves. As his fingers slowly retracted, his cock shyly peeked from the pocket of his boxers. His patience was running thin as he adjusted himself at your entrance—and slowly pushed through. A loud sigh escaped his lips as he bottomed out, his head falling backward as he quietly cursed under his breath. Mirroring his restlessness, your foot hooked around his lower back and pressed him deeper. A drawn-out moan echoed from your throat; he was barely holding on as he gnawed at his lip to contain himself. Reflexively, his hips stuttered before setting a relentless pace—pounding into you with deep, powerful strokes that hit all the right spots.

“Already so wet for me… pathetic. Fucking slut.” His words struck a nerve within—as you repulsively tightened around him, earning a whine. Your moans echoed through the room, mingling with the slap of skin against skin and Mark's grunts of pleasure. He hammered into you like a man possessed—his hands gripping your hips hard enough to bruise as he drove you toward climax.

The long thrusts stimulated every inch of his dick—the veins kissed with every grip of your cunt. “Did your version of me not do it for you?” you teased before taking a sharp breath at his relentless pace. “Y-You really don’t know when to be quiet,” he gritted. “But n-no… not like this. You're much better. I would take you to be a part of my empire.” He replied, his jaw tightening as his hips drilled into you with renewed conviction at the thought. A second you—not the one he’s attempting to keep as a slave for disobeying—but one he could trust to blindly follow his power. His grin grew wolfish as his other hand overlapped your throat—his gaze shifting between your bouncing tits and pleasured face.

The slight closure of your windpipe didn’t allow for much noise—but no matter, Mark began to sing like you’d never imagine. It was strange—the sound was much louder due to your silence as you clawed at his skin. His voice began to crack as his tightened jaw began to slack. "F—fucking incredible," he murmured, his voice rough with satisfaction. "I knew… you'd be worth every s-second of c-...chasing you down," he sputtered as his length began to twitch inside you.

Seeing someone as strong as him unravel before you was a greater sense of accomplishment than becoming a hero itself. With a closed-lip groan, he began overstimulating himself with the effort to get you off. “Haaa… I’m c-close. Ugh…!” you muttered through strangled gasps—as the deprivation of air made you lightheaded and sensitive. Every nerve ending inside your cunt doubled as you went taut beneath him. “C’mon, fucking cum for me,” he heaved.

His thrusts became sloppy as he came inside without warning—doubling over as a consequence. An unfamiliar sensation painted your insides. You both saw stars as silence pierced the room—the slick produced coated his cock in a glaze. Through bated breaths, his fingers finally released their grip around you as you coughed out a response. “I have to admit… you’re hard to deny,” you said, momentarily spent as you lay before him. “Swee—” He was cut off by a voice in his ear.

It was Angstrom demanding his presence over the city. “What a nuisance,” were the final words you caught as he muttered under his breath. Every version of Angstrom was a hindrance to this Mark—nonetheless, he suited up to leave. “I’ll return—and you will join me,” he said confidently, as if there was no argument to be made. You nodded absentmindedly and sighed. Just what had you done?

No Goggles Mark

“Dude…! You’re so cool—what is that? I’ve never seen any powers like that in my world,” he said with an amused expression as he snickered at your agony. You stared up at him, your heartbeat suddenly quickening when meeting his gaze. A look of recognition flickered within his eyes. “Hey, I know you,” he said, his feet touching base on the ground as he approached you with a widening grin. “I’m not sure you know me exactly…” you replied, backing away as your eyes searched for a route to escape—his friendliness had truly taken you aback.

“Who do you work for?” he asked, words flying from his mouth without a care as he approached closer. “You're way stronger than the Guardians of the Globe dudes I fought.” He fought who?! A sense of dread filled you as a new series of questions plagued your mind. If this one could ruin the team to filth—then just how strong was he, and what exactly did he want? “I don't want to fight you, man,” you somewhat pleaded; he frowned with disapproval. “Fight? No, man… but it seems like you’re in trouble, dude.” The topic switched again—his gaze now behind you—as a flurry of aliens attempting their takeover waltzed through a portal. You didn’t have the heart to tell them it was a failed crusade before it began.

Taking a stride forward, a strong arm suddenly wrapped around your waist as you two were propelled to a lone-standing structure where steel beams and concrete floors remained. “Put me down,” you bruised him as you backhanded him into the metal beam. While he had a smile on his face, momentary irritation settled across his features. The painful sting ran to his cock. “Aw, what's the matter?” he asked, standing to his feet as you both came face to face once more.

“It would be hot, but I don't want to fight, dude. I’ve missed you. I promise I’ll be gentle… at first.” The delivery was more seductive—dropping an octave—as he approached you, hands outstretched and finding purchase against your hips. One thing other variants wouldn’t admit—was the supple touch of the right woman could caress their soul.

“I’m not the me you want,” you replied. “You can just be the one I have anyway,” he said. He was indeed serious—and while less terrifying than the other Marks you’d encountered, his strength was menacing nonetheless. “Then let’s see what other talents you’ve got.” Your response made his expression brighten with a new goal in mind. At that, the grin on his face widened as he leaned down and captured your lips in a fierce, dominant kiss.

His tongue forced its way into your mouth, battling yours for dominance as he ground his hips against yours. You two stumbled around the enclosure—footsteps echoing in the empty building. Mark’s hands cupped your ass, squeezing roughly as he whispered crude compliments into your ear. "Nice ass," he growled appreciatively, his fingers caressing the soft flesh. He couldn’t articulate it well—but you were truly beautiful in every universe—and he couldn’t wait to have his share.

Your fingers traveled up his muscled back as body heat pooled across your fingertips. Eagerness unlike any other began to rise as you longed to touch every inch of him. Hero costumes were peeled from one another, and you found his groping becoming progressively obsessive. His hardened cock stood awaiting stimulation as he bit back his urges—sacrificing the time to feel you once more.

Guiding him to the floor, you seated yourself against his lap—your legs hooked over his forearms. He was always too quick to finish battles, and that even applied to sex. Just the tip. That's what you two agreed upon. Sinking onto his cock—its girth filled you deliciously. The wet sound of arousal followed by his restrained groans filled you with delight; it was amusing to see a Viltrumite struggle to contain himself.

1… 2… 3… 4… 5… and 6! On every sixth shallow thrust, you would contract your muscles—gripping his dick like a vice as every vein received a kiss from the gods inside your cunt. It had him crazed—wanting more of your warmth than you were willing to give. “F—fuck, babe, you’re killin’ me,” he hissed with an unforeseen weariness shaking his voice. “Can I?” he started. “No.” His expression hardened at your words. “You’re ruining the—” Before he could finish, he inhaled sharply as his head fell back. “Am I…?” you asked with feigned curiosity. It was undulating in a rhythm that drove him wild. He groaned beneath you—his hands digging into his palms as he fought his urges to misbehave.

The sound of your ass slapping against his pelvis filled the air—mingling with your moans and cries of pleasure. Anything would be worth trading; he could watch his dick disappear within your cunt nonstop. His impending release redoubled his efforts—pounding into you with a ferocity that sent you hurtling over the edge.

The excitement overwhelmed him as he sheathed half his cock inside—the spreading warmth and moisture making his thighs quiver beneath you. His balls tightened, painfully so—that alone ripped a pornographic moan from him. If he could fuck you as desired, he wouldn’t be nearly as needy. Your combined moans echoed through the infrastructure—and you were certain that with the windows gone, someone could hear—but the thought was out of sight and out of mind. Pre-cum beaded down his length as it was smeared each time he entered your warmth. “M-Mark…” you muttered; he nodded fervently behind you as his jaw locked.

“Y-You ready for it, babe?" he asked with a faltering grin as sweat tickled his brows. Leaning your full body weight against him—you felt your orgasm building quickly. The pleasure reached new heights as you both milked each other dry for the sake of proving a point. Your body instinctively began to lurch forward as your orgasm washed over you like a tidal wave. The tip of his cock was bedecked with a foam ring of cum. Mark would’ve begun convulsing had it not been for him carrying you—instead, his body stiffened as he let out a tight-lipped groan. You could’ve sworn you saw his toes curl too—but who knows? His pale skin was flushed a hue of red as his body thrummed with an aftershock.

Once you’d come down from your high, a satisfied grin beamed at you. "Dude, that was incredible," he murmured, a satisfied grin on his face. "We should do this again sometime," he said—as if this was some casual fling, not that you would mind.

Before you could respond, a message in his ear interrupted the conversation. “Ugh… this always happens; I have fun, and then—dude…” he sounded exasperated as he hurriedly redressed—reluctantly wishing you a botched farewell. “I like you. You’re coming with me.”

Feel free to request more lmao

“Since you asked so nicely.” He lifted you up just enough to align his cock to your puckered, twitching hole, rolling his hips upwards just enough to feel the tight ring of muscle start to stretch.

“H- Hhn,” your breath hitched as his dick sunk inside that velvet heat inch by inch.

“Fucking shit..” he suddenly groaned.

You wrap your arms around his shoulders, hiding your face against his neck. You lift your hips and slowly start to bounce on his cock.

“Mmh, Mark..” you moaned, warm breath tickling his skin.

His hips buck upward, meeting your descent with a sharp slap of flesh against flesh. “You feel.. so good. Just like that.”

One of his hands treks down to your ass, gripping it roughly as he uses your flesh to guide your movements—forcing you to take more of his cock with each grind downward.

“N- Nnghh— aah,” you whimper, biting down on his neck.

The squelches and slaps of skin echo through the room, punctuated by your moans and his grunts.

With a sharp gasp, Sinister hilts deep inside you, his cock throbbing as it pumps hot, sticky semen into your ass. You almost yelp, roughly biting down on his flesh to which he yanks you off his lap.

“Ugh..” he clicks his tongue as he drags his fingertips over the deep marks on his neck. “Y’know.. biting is my thing.”

—

Sinister purred when you laid on your back, lifting both your legs up, knees bumping your shoulders—practically folded in half.

He's still rock hard, not a single sign of him softening after his first orgasm. And the new angle allows him to sink even deeper into you.

You feel so incredibly full, stuffed to the brim with his pulsing cock.

He starts to roll his hips, sawing his thick shaft in and out of your stretched, slick hole.

“A- Aahh— Maaark!”

“What would, ngh, your Mark think if he saw you like this?”

“D- Don’t talk about him right now!”

He snickered lowly as angled his hips, hitting your prostate inside dead on.

“Mmmhh—“ You whined loudly, eyes glazed over.

Sinister pulls out slooowly then slams his cock back in with sharp thrusts.

Your noises got louder—panting, gasping, moaning. You weren’t even trying to hide your pleasure.

The creaking of the bed frame fills the room as he fucks into you wildly. His heavy balls slap against your ass with each vicious thrust.

“Aah! U- Uuuf.. ohhh, Mark!!”

You were practically seeing stars—nothing has ever felt this good before. “I- I need to— mmphh, cum.”

You let out shaky pants, eyebrows knitting together in overwhelming sensation, legs starting to shiver. “Fuckfuck…”

Sinister groaned at the sight.

He reaches down with his free hand, finding your dripping erection. He wraps his fingers around it roughly, stroking you in time with his thrusts. His thumb swipes over the sensitive head, smearing the leaking precum around.

“Cum for me. Don’t try to hold it in.”

With a deep, final thrust, he slams into you and grinds against your prostate. His hand squeezes your throbbing cock.

Your entire body seizes up, hole fluttering and clenching around him as you came—cum spurting from your aching dick in thin rivulets.

“S- Shit, Mark!” You practically yelp, looking up at him with the most pathetic eyes he’s ever seen. More pathetic than the many people he’s killed.

He lets your legs down and scoots back a few inches. “You good?”

“Uh, mhm.” You nod, slowly moving to sit up.

“Wait.”

“..What?”

“I want to keep fucking you.”

You blink slowly.

“..Please?” He tilts his head slightly.

You let out a heavy sigh and lay back down.

—

His fingers dig into your hips, pulling you back against him.

He admires the new view—your ass sticking up for him, your back arched, your body slightly trembling in anticipation.

He spits into his palm, rubbing the slickness over his still-hard cock before pressing the thick head against your hole.

“You’re still so tight,” he grunts, pushing forward just enough to make you gasp.

His free hand slides up your spine, gripping the back of your neck as he leans over you. “Your Mark is going to wonder why you’re stumbling around tomorrow.”

With a sharp thrust, he buries himself to the hilt, his hips slapping against your ass with an obscene plop plop plop.

His grip on your neck tightens, forcing you to arch deeper.

“F- Fuck—wait! It feels s-s’good!”

Sinister grins at your words, his thrusts becoming more brutal that your body starts to jolt forward with each time your skin meets with his.

He leans down, his teeth sinking into your shoulder. You let out a sharp whine in response.

Your fucked-out face pressed against a pillow covered in your drool. The pleasure is so deep that it borders on painful, your ass clenches around Sinister’s thrusts until the bed is soaked beneath you, your cum spurting and dribbling from your cock.

You draw out another moan.

He fucks you through your orgasm, pace faltering just a little as he fights his own release.

“Nngh..” He pulls out at the last second, jerking himself off until he spills across your ass and lower back in hot, heavy pulses, the mess sliding down your warm skin. A breathy curse slips from his mouth.

—

The scent of sex and sweat lingers in the air between you, a thick reminder of what just happened.

Sinister huffed as he laid back against pillows, watching as you hooked your bare leg over his hip, your chest almost fully on top of his.

You unconsciously sucked and nibbled at his neck as if it was second nature, your hand firmly holding his jaw on the other side.

He wrapped an arm around your waist and looked down at you with a satisfied, lazy grin, taking in the sight of his cum on the curve of your ass and the small of your back. His other hand treks down to trace through the mess, scooping some up with two fingers and pushing it back inside your fucked hole.

He’s not looking for another round just yet, but he likes the way you cling to him, the way you currently need him.

He shifts slightly, pressing his chest firmer against yours, enjoying the subtle contrast between your body and his. You murmured against the skin of neck and bit down harder when his fingers slipped inside.

“Yeah, that’s it..." he mumbles, his voice thick with post coital content. He can feel how sensitive you've become, the walls of your hole throbbing rhythmically around his fingers.

He slides a third finger in, stretching you wide again, his hand working with a steady kind of grace. He isn't exactly being gentle, but he isn't being brutal anymore either. It’s a slow, possessive kneading.

“Mmm..” you whine quietly.

And suddenly the door slowly opens—

Mark’s voice was soft, like he expected you to be asleep when he walked in.

“I know it’s late and I shouldn’t have broken in, but—”

He cut himself off at the sight of Sinister fingering you.

You were supposed to tell him as soon as you saw the guy. You were supposed to tell him if something was wrong. You were supposed to—

The one thing you weren’t supposed to do was hide the fact you were keeping Sinister at home and fucking him behind Mark’s back.

“..What the hell is this?” Mark stares in disbelief.

Sinister’s body stiffens under you, but he doesn't make an effort to cover you or move away in shame.

Instead, he slowly drags his fingers out of your slick, gaping hole with a wet sound that echoes in the sudden silence.

He looks the doorway, his eyes meeting his own—well, Mark’s wide, horrified gaze. Rather than looking guilty, he looks incredibly annoyed, his brows furrowing as if his intrusion has ruined a perfectly good moment.

“I asked a question.”

Mark’s hands clench into tight fists. His eyes flicker to your nude, sweaty body draped over Sinister’s, then back up to his irritated glare.

He gave Mark a cocky smirk. "What? You caught us post fuck." His voice was lacking even a hint of apology. “Don’t look so shocked, it was bound to happen with me and him.”

“You’re serious.”

It’s not even a question.

Everything that made sense five minutes ago—everything that felt intense, confusing, impossible to untangle—suddenly feels a lot more real under his gaze.

You push yourself up slightly, finally aware of how this looks.

Of what it is.

“…Mark, I—”

“You lied to me.” He cuts you off, sharp.

“I asked you,” he continues, taking a slow step closer. “More than once. If something was wrong. If he came back. And you just—what? Kept him here behind my back!?”

You don’t have an answer. An honest one at least.

His jaw tightens.

“How long has this been going on?”

You’re silent again.

And that’s your answer.

Mark lets out a sharp, disbelieving breath, running a hand through his hair like he’s trying to wake himself up from a bad dream. “This is messed up. This is really messed up.”

You nod hesitantly. “I know.”

“But you still did it.”

Not accusing.

Not even fully angry.

Just hurt.

“I didn’t know how to tell you..”

“You could’ve started with anything,” Mark snaps, the frustration finally coming through. “Instead of—this!”

Sinister sits up slightly, gaze fixed on Mark. “He wasn’t going to tell you.”

You tense up even more. “Stop it—“

Mark’s eyes snap to him. “Don’t speak for him.”

“I don’t have to,” Sinister replies. “He already made his choice.”

“Dude,” Mark says, looking back at you, “this is him. The guy who literally kidnapped you. The guy we’re supposed to be stopping. And you—”

He gestures helplessly, like he can’t even comprehend the thought.

Your chest tightens. “I- It’s.. not that simple.”

That stops him for a moment.

“No, no, you’re right! I get it, you’re choosing him.” Mark spat out sarcastically, disbelief bleeding into every word.

You flinch.

And that says everything it needs to.

Mark laughs once. “Wow.”

Sinister doesn’t look surprised at all. If anything, he looks satisfied, still completely unapologetic. “Told you.”

“I trusted you,” he says.

You swallow, your voice quieter now. “I know.”

“Did you?” Mark asks. “Because it really doesn’t feel like it.”

He takes a few small steps back. Like he needs distance before he says something worse.

“I need a minute,” he mutters, more to himself than either of you, slowly turning around. “We’re talking about this later.”

Then he’s gone.

And the room feels colder without him.

“He’ll come back,” Sinister says. “I would know.”

You’re caught between the person you’ve always known and the one who refuses to let you go.

But no matter what happens next, you’ve already crossed the line.

And there’s no going back from it now.

“…Shit.”
