Rex choked out a pained grunt as his back slammed against the hard floor. His back arched in agony, pushing his body against the one that had him pinned down. He tried to twist away only for a strong hand to slam against his chest to lay him flat on the ground. The force on his chest made him wheeze.
He wished he was helping Rae lift her mattress up the stairs right now. Or really, doing anything other than dealing with a sadistic, homicidal version of his crazy strong friend.
”I appreciate you giving us the chance to have fun without any interruptions,” (Not)Mark’s breath felt hot against his ear as he leaned in, “but as soon as I’m done with you, I’m going to find your little friends and leave them as red smears for Cecil to find.”
Rex gritted his teeth painfully. There’s no way in hell he’s going to let this freak hurt them. He’s going to take down this fake Invincible right here and now. He’ll even drag him to hell personally.
His hand slid over towards the gash in his side, feeling conviction in his decision. When the Mark’s gaze drifted down to the movement, he involuntarily held his breath for a moment.
“Worried about bleeding out?,” the imposter scoffed. “You are so fucking pathetic.” Mark plunged two of his own fingers into Rex’s gaping wound, ripping out a pained shout from the redhead.
Rex grimaced and wriggled under the monster wearing his friend's face, wishing those government goons removed his ability to feel pain when they grafted this shit to his nervous system. On impulse his mechanical hand shot up to grip the forearm of the hand that was plunged into his side, even knowing he hadn’t the strength to pull it away.
He let out a strained laugh. “Not… exactly how I imagined it… when I thought about Mark pushing against my guts.” He swallowed a groan when the fingers suddenly inched in deeper. “Fuck… couldn’t at least get a Mark with a sense of humor…”
“A filthy slut in every universe,” the imposter hissed. “The me from this world really never fucked you? Not one for easy lays and sloppy holes? I was never so picky.”
Unease settled in Rex’s stomach. The thought of him, or a version of himself, ever letting someone like this freak touch him like that makes him gag. “You… and the me from your world…?”
Mark’s lips twisted into a cruel and sharp smirk. “My Rex knew his real use, you were never cut out to play hero.” The Viltrumite’s free hand dragged down Rex’s body with a feather-like touch. “On your knees, on your back, serving your betters. He only ever had the nerve to deny me at the end, after me and dear old dad subjugated your pathetic race. And do you know what I did?” His free hand slid down to Rex’s crotch and firmly groped at his flaccid cock. “I fucked him anyway.”
“Sick freak.” Rex’s teeth clenched in frustration and cold rage.
The imposter chuckled.
Rex shut his eyes in disgust as the other continued rubbing his cock through his pants. He pushed at Mark’s shoulders, trying to miraculously summon the strength to force him off. A foul tongue licked at his neck, lapping up the sweat and blood that covered him. A pleasant warmth and sickening shame pooled together in his gut.
With his metal hand he punched the fake Mark in the dick.
Mark grunted and Rex took advantage of the shock and shoved him away enough to pull out from under him. He rose to his feet but just after a few wobbly steps his knees buckled, sending him crumpling back to the floor.
Still, he used his hands to drag himself across the ground. Desperate to get a moment to collect his thoughts and re-strategize. Desperate to get away from those invasive hands. Desperate to spare his teammates from a terrible fate.
An awful screech was ripped from his throat as a foot slammed down on his ankle. The sharp snaps of his bones breaking were loud in his ears.
Covered in blood. Broken bones. Doing his best to just stay alive. A familiar scene, too familiar. It felt impossible to breathe.
“You’re not going to get away from me, you dumb little bitch.” Mark got down to straddle Rex’s waist and flipped him back around. Mark pulls down the waistband of his costume and fished out his cock. ”Before I fuck your ass, I know which hole I want to try first,” words spoken as he lined up against the bloody slit.
Rex resigned himself to the Viltrumite’s whims. He wasn’t going to make it out of this and his last moments on Earth were going to be spent as a monster’s fleshlight. He can only hope Rudy and the others made it as far away from this place as they could. That would be enough for him.
His head was thrown back in a silent scream as the other’s thick cock pushed into the gash. His limbs twitched uncontrollably, willing him to fight against the intrusion. But his body felt far too heavy.
The hero looked down at the offending appendage as it slowly forced its way past skin and fat and muscle. It only got less than half way inside of his body before the variant began pumping in and out of the sore hole. His blood smeared on Mark’s cock and more was pushed out of the wound with each thrust. Rex let his head fall back against the floor as a wave of nausea hit him. He lay there twitching and moaning in pain.
“You should see your face right now, you look like you’re getting fucked for real. The way your eyes roll back. Your slutty moaning.” The Viltrumite brought a hand to the hero’s face and swiped his thumb through the wetness Rex hadn’t realized was there. “You’re even crying. Does it feel that good? Is my cock everything you imagined it to be?”
“Shu-ugh, ow!- Shut up. Shut the fuck up.” Rex was so over villains driveling on and on as a way to jerk off their own ego.
“Fuck, you’re so hot like this. Bleeding out on my cock. Your face stained with tears.” Mark’s pace quickened, still keeping his thrusts shallow. “You feel like hot shit now? Where’s that playboy persona you put on? Not so confident when I’m raping your guts, huh?”
“Jesus Christ. Is this-“ Grunt. “-your idea of-“ Whimper. “-dirty talk?“
The variant leaned down to bracket his forearms on either side of Rex’s head, smirking down at him. Rex glared into the other’s visible eye from the shattered goggle lense before crying out as Mark pushed deeper into him, not stopping until he was fully sheathed inside the wet warmth.
Rex choked on a sob. His breathing became rapid and stuttery. Mind too focused on the feeling of Mark’s hips flushed against his gored abdomen.
“Fuck… You feel so good. I could cum like this…” His lips lightly grazed against Rex’s for a moment before forcing them together in reckless abandon.
The redhead did little to dissuade the action, yearning to feel anything but pain. He let the other’s tongue invade his mouth and even began kissing him back. He didn’t have the mind to feel too much shame about it. Pained whimpers mixed with ones of pleasure. A wet slap rang in his ears when Mark finally pulled away.
Mark pushed himself up on his hands. He began gradually pulling his cock free from Rex’s body, the gash now gaping wider. The man chuckled at the sight, “I really stretched you out.”
Rex cringed at the scene of the imposter’s erection dripping crimson. He watched as Mark climbed lower down his body to reposition himself between his legs. The hero laid still as the Viltrumite tore the crotch of his tattered pants apart, pulling the fabric until the pant legs were fully split. His limp cock and puckered hole now bared before his attacker.
“Thanks for lubing me up.” Mark rose to his knees. He gripped Rex’s hips and pulled them up to be leveled with his own.
Rex was forced to balance his weight on his shoulders and the tips of his feet. The hands at his waist held him firmly in place. In a different timeline, one where all of his blood was inside of his body, he’d flush being manhandled by Mark like this. Instead, the hold on him felt oppressive. It marked his ruin.
The redhead whimpered as Mark steadily forced himself inside his unprepared hole. The painful stretch made his body tense. He yelped when the other lost his patience and slammed in the rest of the way. “O-ow. Asshole.” It hurt but there was an undeniable swell of arousal. Weaved between the pain were sparks of pleasure. The angle forced the Viltrumite’s cock firmly against his prostate. His legs trembled.
He felt so full. Mark felt impossibly big buried in his ass. For a morbid moment, he wondered if his organs would be forced through the hole in his side, pushed aside by the other’s girth.
“Shit, you’re tighter than I remember,” Mark moaned. The fake rolled his hips against his captive.
“‘M not him,” Rex murmured in response. Fuck this Mark, fuck his Rex and fuck whatever fucked up drama happened between them. He’s not actually the person that earned the other’s ire. He lamented how unfair it was.
Mark held his hips in place as he started fucking into him. Small moans slipped from Rex’s lips as the Viltrumite slammed into him with inhuman strength. His prostate was pummeled so brutally he wondered if it could bruise. His voice grew louder as his ass was continuously pounded. Skin slapping against skin seemed to echo off the walls.
“Feel good? You getting off on being raped?,” the Viltrumite mocked. “You’re still soft though, not enough blood left to get it up? That’s fine, I bet I can make you cum like a girl.”
Rex gasped when the Viltrumite sped up his thrusting. Those strong hands pulled him in to meet each plunge of the other’s hips. His breath was punched out of his body with every slam. He’s never felt anything so intense in his life. Drool and tears dripped down his face.
Mark had begun muttering under his breath. Whatever he was saying was drowned out by Rex’s own heartbeat thumping wildly in his chest. He could feel himself getting close, he was really going to cum on his rapist’s cock. That thought only seemed to make the assault on his body feel more intense. His face burned with shame.
“Pluh-please don’t-!” Don’t make me cum, he wants to beg. Spare him the humiliation of cumming from his own rape. But he can’t even get the words out. They were caught in his throat, they scraped against his esophagus like thorns.
“Are you close? Come on, Rexy, cum for me.” The imposter’s voice was breathy, likely on the edge as well.
Rex came shouting his friend’s name, “Mark! Mark, oh God!” He clenched down, earning a hiss from the other. Despite still being flaccid, spurts of cum shot out of his cock. Waves of pleasure rolled over his body as the Viltrumite kept fucking into him.
“Fuck, I’m cumming!,” Mark moaned as his thrusting stuttered. He flooded Rex’s insides with hot cum. He pulled the hero tight against him and rocked into him as he rode out his orgasm.
They were still for a few moments. The most movement came from Rex’s heaving chest as he drew in air.
When the Viltrumite finally pulled out, he unceremoniously dropped Rex’s waist. “Look at you… Utterly wrecked,” satisfaction bled into his voice. He leaned over the hero with a lopsided smile on his face.
While the evil Mark was basking in his twisted feelings, Rex’s hand darted out and reached into his mouth. He watched as Mark’s head reeled back in surprise but the damage was already done. He watched as the other’s expression turned to rage and disbelief as his teeth glowed with energy. Rex didn’t smile, this didn’t feel like a victory.
Rex flinched as the imposter’s head was blown apart. Blood and brain matter splattered on his face. The body fell over and onto him. He laid there, trying to process everything that’s happened, and screamed. It was fueled by raw emotion. His already sore throat felt like it would bleed.
He doesn’t know how long he spent yelling his heart out but it came to a halt once he heard new voices.
“Rex?!”
“Oh my God, Rex!”
Tears swelled in his eyes. The two voices he wanted to hear the most. The two people that he didn’t want to see like this.
The headless body was flung off of him as Mark and Eve’s face came into view.
Mark, the real one, gently cupped the back of Rex’s neck and lifted his head slightly. “Rex…” His voice was choked with emotion. It was refreshing for Rex to hear. “Rex, you’re gonna be ok. We’re going to get you help.” The redhead was gently scooped up In strong but kind arms.
Eve covered her mouth in horror with one hand and used the other to fix his clothes with her power. She also conjured bandages and tightened them around his midsection.
“I got one…,” Rex’s lips quirked up.
“Y-yeah. You did good,” Mark stuttered out a response. He forced himself to give a comforting smile.
“You were so, so brave, Rex.” Eve spoke softly and ran a hand over Rex’s head in a petting motion.
Rex sighed in content. And closed his eyes.
