"Mark...? Are you in there?"

Cesar felt dread pool in his gut at the lack of response. Apparently, Mark had rushed out of his house due to a family emergency, and hadn't realized he didn't make sure to double-check if his windows were locked until he was already on the road. He had called up Cesar earlier, asking him to do him a favor and drive out to his house to check on everything. Cesar had said yes, he had been friends with Mark for a long time and he was happy to do something so simple for him, why wouldn't he?

He starts questioning if he made the best decision when he parks his car on the street, because Mark's car is still sitting in the driveway. He feels fear settling over his body when he turns the front door's doorknob and finds it already unlocked, hinges creaking as the door opens to the forebodingly empty hallway. He wanted to help his friend, but as he stood in the doorway and faced the suffocating darkness of the house, he was beginning to want to turn around and call the police instead.

It's too bad he never gets the chance to do that.

A hand tears out of the inky shadows of the hallway, snatching the front of Cesar's shirt in an vicegrip and yanking him into the darkness. He shouts, falling forwards as he is forced to stumble into the house, flailing his arms in front of him for balance. He hears the door shut behind him, slamming shut like the lid to a coffin, and fear floods his body like his blood has been replaced by ice.

"What the fuck, what the fuck, what the fuck?!," Cesar yells, his heart thundering in his chest and terror gripping his mind. He can't see, and he backs up, trying to find the door so he can tear it open and get the fuck out of the damned house. Before he can even take more than two steps, something big and heavy and fast tackles him to the floor, pinning him down on his back as it presses its full weight onto his chest. He tries to scream, but all that comes out is a pained wheeze as the air is knocked out of his lungs.

"Ce-e-e-e-sarrrrrrrr," a confusingly familiar voice drawls, seeming to almost glitch on the vowels.

Cesar's eyes adjust, and slowly, the shadowy figure looming over him clears into the image of Mark- no- not Mark. An alternate? Whatever it is, it's wearing Mark's face, the shadows of his home pooling in the dips and curves of his stolen face unnaturally, and indistinct shapes that look like writhing snakes are waving in the air behind it. It's eyes have a malice in them that the real Mark could never muster, and it looks so wrong,

"What the fuck are you!?" Cesar tries to sound intimidating, but fear seeps into his voice anyways.

"Your best friend," 'Mark' grins, "or what's left of him, anyways."

The response fires off alarm bells in his head, and sorrow eats a pit into his gut as he registers the implications of its words. "Where's Mark?" Cesar asks weakly, not really wanting to hear the answer.

"Oh, poor Heathcliff," 'Mark' tuts, clicking its tongue. "Left his window open, thought he'd be safe since he's on the second floor, you know?" It leans forward, pressing its forehead against Cesar's until he has to cross his eyes to make eye contact with it. "Well, I think you can guess how that turned out."

Tears well up in Cesar's eyes at the confirmation that Mark is most likely dead, and had been killed by the creature masquerading as him. "Fuck you," he grits out, torn between hatred and sorrow as he stares up at the monster above him.

"Oh," it stretches its lips into a grisly smile, "gladly."

It spins him around, forcing his face against the floor as it flips him onto his stomach. It presses its chest against his back and clamps its arms around his torso in a bear hug, pinning his upper arms to his side. His arms are free below the elbow, but he can't move them much, no matter how much he struggles. It lifts him off the floor, forcing them both into a kneeling position. Cesar's mouth goes dry as he feels tentacles squirm their way under his waistband, pulling his sweatpants and boxers down past his waist.

"Wait- stop, don't-!" Cesar splutters as it tugs his clothing down to his knees, writhing uselessly as it exposes his most closely held secret.

"Oh?" 'Mark' hums, its tone rapt with interest and bemusement, "What do we have here?"

Cesar gasps as one of its tentacles slides between his folds, rubbing up against his t-dick. It's slimy, leaving a trail of slick on his skin as it teases him threateningly. He grits his teeth as the tip of it wriggles into his hole, just barely entering him before lazily slipping back out.

"How fascinating," the alternate gasps exagerratedly, "I didn't know you had a perfect little hole for me to breed! It'll be much easier for me to knock you up this way. Saves me a lot of trouble, honestly."

"Wh- knock me up?" Cesar squeaks out, hoping he had misheard it.

"Oh, yes," it drawls, letting its hot breath tickle his ear. "I'm going to fill you up, see if you can carry a whole litter... and if you can't, then I'll just try again until it takes."

Cesar can't find any words to respond to that with, and lets the silence hang heavy over them. He wasn't interested in anything to do with having something go in his pussy, so he's never bothered with birth control. There's nothing stopping the alternate's threat from becoming a reality. Even if by some miracle he doesn't get pregnant from this, it'll happen eventually if 'Mark' sticks true to its word and has its way with him until it's successful.

"Hmm? Nothing to say?" 'Mark' coaxes, a cruel smile stretching its face.

Cesar knows there's nothing he can say to save himself. "Fuck you," he whispers, rage and despair and defeat lacing his words with a potent, yet pitiful, venom.

'Mark' chuckles, "Oh, I'll be the one fucking you, sweetheart." It drags its tongue over the side of his neck and Cesar's face scrunches up in disgust, despising the way the alternate finds a way to use his own words against him.

Cesar feels something slide between his thighs, coating his taint and folds in slime. He looks down, and feels his heart plummet down into his stomach like a stone as he registers the sight of what's going to be forced inside him. It's big, and completely inhuman; the head is bulbous and wrinkled where it meets the shaft, which has an odd shape and slight curves on it. Cesar can't see the seam running down the underside of the shaft, but he can see the member increase in width as it throbs and twitches, the extra skin allowing it to adjust how wide it can stretch like the jaws of a snake.

He doesn't even get a chance to properly process the moment, because it's already pushing past his folds and stretching his entrance. Cesar finds himself unable to speak, just hissing and spluttering in pain and fear as he's stretched for the first time in his life by something far too large for him to take.

"Christ, you're tight. Are you a virgin? Hm?" the alternate teases, not even a quarter of the way inside him yet, but still making Cesar whine in pain. "This'll be a lot of fun, then... only for me, of course. Unless you're a massive fucking whore, I would love to hear you moan while I fuck you."

Cesar still can't respond, face twisted in agony from the stretch he's being forced to acclimate to. He tries to bash the back of his skull into his captor's face as punishment for its vulgar comment, but it's no use; he's still defenseless. He can't blink away the tears blurring his vision anymore, and a few start to slide down his cheeks, rubbing salt into his wounded pride.

He croaks out a sob as 'Mark' finally bottoms out inside of him, filling him up to the brim with its cock. He pants raggedly, squirming in discomfort from the burn of the stretch and the new sensation of being filled. Much to his surprise, the burn is fading; it still hurts like a bitch, but it's receding to something less agonizing. But even with the odd numbness and ludicrous amount of slick, Cesar knows this is far more than he can take, and he feels like he's going to split in half.

"I-I can't, please. Please stop," Cesar pants, desperation winning over his dignity, pleading with 'Mark' to end this torment.

"Sorry, sweetheart, but we need to finish what we've started... and we've barely even gotten started!" 'Mark' crows, bucking its hips into Cesar and forcing a pained yelp from his lips.

Cesar growls at it, but his agression is soon replaced by fear as the alternate pulls out of him, the feeling of its cock dragging against his insides terrifyingly foreign to his body. It slowly plunges back into him, and he grits his teeth, more tears threatening to spill. It does it again, and again, finding a rhythm as it slides its dick in and out of his hole, making Cesar wince with each tug and jab to his insides.

"Mhh!" Cesar stifles a surprised moan when it thrusts back into him and makes contact with a spot inside him that sends a jolt of pleasure through his body. He flushes, mortified and terrified that he might be forced to feel pleasure during this ordeal.

"Oh, are you going to make little noises for me?" Mark whispers huskily in his ear, and he shivers, shamefully aroused by the sound of Mark's voice.

It slams into him brutally, drilling into his g-spot with no mercy. Cesar gasps and chokes down wanton moans, only successful in stifling half of them. The noises that do slip out of him are downright mortifying; high-pitched keening is punched out of his lungs with each perfectly angled thrust, making him sound like he's a twink straight out of a b-list porno.

'Mark' speeds up its pace, and Cesar belatedly realizes that he can't even feel much pain anymore. He can only feel the burn and agony of pleasure coursing through his veins as it fucks into him like an animal; dirty and messy and depraved. He's never felt so violated, but nothing has ever made his feel this good either. Stifling his moans and yelps of pleasure is getting harder and harder as the heat overwhelms rational thought. The defeat of his mind is only spurred on by his body as it forces him to clench around the alternate's cock and leak slick until it's dripping out of his needy cunt.

"S-stupid fucking, ah, whore," 'Mark' grunts out, "bet you love my fucking cock, love getting your guts rearanged, hm?"

"N-noo- mmh- No! Fuck off!" Cesar shouts, hating the way his dick twitches at the words being spoken in Mark's husky voice. He loathes how much he loves it, wishes he could stop thinking of the real Mark doing this to him, talking to him with that low, scratchy tone as he fucks Cesar mercilessly.

"The fuck was that? You wanna run that by me again, fucker?" 'Mark' snarls, biting into his neck hard enough to bruise, crushing the delicate skin between its teeth.

Cesar whimpers in pain, then gasps as he feels one of the tentacles latch onto his clit, forcing his t-dick into a slit at the tentacle's tip. He moans as it begins suckling his cock; sliding up and down like a fleshlight, tantalizingly tight and wet around him.

"Ah- please- mmnh-!," he chokes, not sure if he's asking for 'Mark' to stop or keep going as his head spins from the pleasure overwhelming his brain and wrapping his head in cotton.

"Yeah, that's what I thought. Keep making pretty noises for me, Ces."

"H-hah..." is all Cesar can respond with, losing his grip on reality. Maybe he's just having a weird dream, maybe if he imagines the real Mark is the one fucking him then it won't hurt as much.

"Fuuuck, you feel good around me, so tight and wet, bet you're gonna milk me dry, aren't you? Fucking cumslut," 'Mark' growls, burying its face into the hair on the back of his head.

Cesar groans at the rough treatment and degradation, too breathless to speak. Yes, he thinks to himself instead, I need you Mark, I'm gonna take anything, everything you give me... so fucking good. If he was more aware of himself, he would be incredibly grateful for his inability to voice his thoughts. Instead, he can only moan and grunt as he's pushed closer and closer to his release.

'Mark' chuckles at the lack of a coherent response. "Needy whore, you're too fucked out to even be a brat anymore, hmm?" It licks the back of his neck, making him shudder. "That's almost a shame, I like how fiesty you are... seeing you like this is a treat, though."

"Mhhn! Hmmhn-!" Cesar whines in response, his moans getting punched out of his mouth with each thrust. Please, please, please! Fuck! Cesar wails internally, begging for Mark to go harder, faster, anything, just more.

As if it can hear his pleas, the alternate's thrusts become harsher, less coordinated and more desperate. "Fuck, 'm close... gonna breed you, gonna stuff you full..." it pants, hot air hitting his ear as it strains to go harder.

The thought of Mark breeding him is sending all sorts of mixed feelings to Cesar's brain, but he doesn't care anymore. He needs Mark to come in him, now, he's so close, he's nearly crying from how badly he needs this, needs Mark, needs all of him.

Mark!, "Ah!" I need you, I need you, Please-!

"Hah- mnnh, mmh-Mark! Maa-a-rk I- nngh-!"

Cesar screams as the alternate rips an orgasm out of him, wailing in ecstacy as it pounds his g-spot and cervix over and over again. He comes around the alternate's cock as it continues slamming into him, and his release splatters against the back of his thighs and the alternate's hips, soaking them both. Cesar's vision nearly whites out as it speeds up its pace, overstimulation making him whimper and gasp.

'Mark' buries its cock deep inside him as it snarls, the head of it harshly jabbing against his cervix. Cesar feels something warm and thick gushing against his inner walls, filling Cesar to the brim as it starts shallowly bucking its hips against him, shoving its seed even deeper inside. Its load is too much for his body to hold, and semen flows out of his cunt in thick streams, pooling onto the floor and dribbling down his thighs. It seems to go on forever, and Cesar can only hang his mouth open and drool, slack-jawed and fucked out.

Cesar pants, limp in the alternate's hold as 'Mark' finally goes still inside of him, squeezing him tighter and nibbling the side of his neck. He thinks it must finally be over as it slides its shaft out of him slightly, but he is soon proven wrong. Stars dance in his vision as it rams its dick even further into him, piercing through his cervix and planting itself deep inside him. He shrieks in pain, but it soon fades into pleasure and heat that makes his cunt pulse and throb for more. The head of its cock nestles into his womb and pumps even more cum into him, making Cesar's eyes roll up into his head. He trembles, fucked out and clenching around the cock inside him. He's too tired to think, he just hopes 'Mark' gets tired of this and stops soon.

The alternate finally stops coming, and goes still inside of him, panting like a dog as it comes down from its high. Cesar feels disgusting, violated; he was forced to enjoy the worst night of his life, and 'Mark' will probably hold it over his head for the next nine months, never letting him live it down. His heart clenches as he remembers this is only the start of the nightmare; the next nine months of his life are going to a living hell. He desperately wants an escape, and he's honestly considering just killing himself to avoid his fate. He doesn't want to, he wants to live, but he's not sure if he can survive this.

The alternate groans and wraps its tentacles around his thighs to force his hips flush against its own, snapping him out of his spiralling thoughts. Cesar screws his eyes shut as he feels... something swelling at the base of the alternate's dick, pressing against him from where their hips meet. Before he can process it, it's pushing past the rim of his hole, solid and hard. He stifles a whimper as it stretches him open even more, his walls bulging around the intrusion as it enters him. It feels as if whatever it is, it's traveling through the alternate's shaft, inching deeper and deeper into him. It reaches his cervix, and Cesar feels something being pushed out of the cock's tip and deposited into his womb. He presses a hand onto his lower belly and he thinks he can feel it through his skin, or the vague shape of it, anyways. From what he can tell, it's oval-shaped, smooth, hard, and keeps it's own shape.

"W-what is that," Cesar chokes out, "What did you put in me?!"

"Shhh," 'Mark' whispers, making Cesar shiver as its breath ghosts past his ear, "it's okay, little rose, it'll feel good."

He whines as another lump is pushed into him, pressing against his g-spot as it invades his insides. When it reaches his cervix, he tries to push down on his belly, hoping it won't be able to fit inside him if he does, but it forces itself into his womb anyways. He feels the new lump click against the first one inside his womb, confirming to him that he was right about them being hard; but it leaves him with more terrifying questions than answers. Fear sinks into his bones as the reality of the unknown situation dawns on him.

"S-stop! Stop it!" Cesar sobs, "What are you doing to me?!"

"Oh, I think you can figure it out yourself," the alternate coos, "go on, guess what it is!"

Cesar pauses, and tries his best to think through the haze of panic fogging up his mind as another object is forced into him. It drags against his walls in just the right way to make him have to swallow a moan, making it a bit hard to focus. Whatever the objects are, they are coming out of the alternate's dick, and being forced into his womb. Each one is maybe about the size of his fist, and are slightly oval-shaped. They're hard, almost like they're covered in a shell...

The answer clicks in his mind all at once, just as the third object settles inside him. "You... are you laying eggs in me?!" He wheezes, praying to anything that will listen that he's wrong.

"Bingo! See, you figured it out, so smart! It's one of my favorite things about you, you know," 'Mark' sings into his ear as it pushes another egg into him, making Cesar squirm in discomfort and pleasure. "Mark was smart too, but always a little distracted, took him longer to realize what was happening... it was like boiling a frog, really, he didn't notice anything was wrong until it was too late." It chuckles cruelly, and Cesar scowls despite the fact it can't see his face, wincing as he feels the egg getting pushed into him and bumping into the others inside him.

"Shut up, don't talk about him like that, shut the fuck up-"

He's cut off by another egg pressing up against his g-spot, wrenching a ragged moan out of him. He pants, trying to collect himself as the aftershocks of pleasure course through him. Why does it feel so good suddenly? Each egg that presses against his insides feels better than the last, and the stretch is only mildly uncomfortable instead of excruciatingly painful like it probably should be. He finds himself wondering if the alternate's cum contains some sort of aphrodisiac or something.

"Heh, looks like I shut you up instead," 'Mark' snickers, poking Cesar's face with a tentacle. "Do me a favor and stop running your mouth, you're much cuter when you sit on my cock all pretty and moan for me."

What the fuck!? Cesar thinks to himself, seething. He's about to come up with a nasty retort but instead he lets out a strangled gasp as another egg squeezes into him, lighting up his insides with pleasure.

"A-ah! I-ah, hah," he moans wantonly, unable to string words together, "St- mmh, ohhh, ah..."

"See? Feels good if you stop whining and take it like the little slut that you are," 'Mark' sneers, reaching down to stroke Cesar's dick, sending electric pleasure shooting through his nerves. It nuzzles the back of his head as it fingers his cock, breathing in his scent as he trembles underneath it.

"Sto-o-oh-hah! Mmhn..." Cesar sobs, cutting off his own protests with more embarrissingly loud moans. He desperately wants to fight, but he's too exhausted to even squirm anymore, and he's even starting to have trouble holding his head upright. He resigns himself to the bizarre new form of torment, trying to distract himself from thinking about it too much.

It proves to be difficult to ignore. He can feel every twitch and pulse of the alternate's cock as it fills him with egg after egg, strange muscles contracting in time to each spark of pleasure that forces him to clench around it, squeezing the objects further into him. Each time he feels the rim of his hole stretched by a new egg, he mewls weakly as it invades him, and then moans brokenly as it is squeezed directly into his g-spot, exerting pressure on his senstive insides as it travels through him. He whimpers weakly at the feeling of it being crammed into his womb; the stretch and pressure of the intrusion uncomfortable, then sighs as it releases, settling inside him.

The cycle continues agonizingly slowly, and he loses count of what number of eggs has been forced into him. All he knows is that there are enough eggs inside him to make his belly swell bigger and bigger by the minute, making him feel fuller than he's ever thought was possible. His skin is stretched taut over them, and the outline of each egg is visible from the outside. One of the alternate's tentacles carress the sensitive skin of his stuffed belly gently, tracing each lump that bulges from his skin.

By the time 'Mark' finishes laying its eggs in him, he's nearly unrecognizable. His belly is swollen and bumpy, ballooning out far past his usual girth and looking concerningly painful. His face is coated in a thin sheen of tear-tracks and sweat, and he has the most depraved, fuck-out expression on his face; unable to stop his eyes from rolling up into their sockets, and letting his tongue loll out of his hanging jaw as he gasps for breath. When it finally pulls out, Cesar is completely and utterly spent. His cunt pulses around empty air, still aching to be filled, drooling cum and slick onto the floor. 'Mark' chuckles at the sight, then picks him up and unceremoniously dumps him onto Mark's couch, chuckling as he lays there, dazed and aching.

"I've got to say, I can understand why he liked you so much, you're very fun to play with," 'Mark' sneers. "I think I'm going to enjoy the next couple of months..."
