“Kris? Y-you in here man?...“
“Looks like he ran off. Figures a human would play hooky from school!”
“Berdly! Don’t talk about him like that! Who knows, maybe Susie dragged him off… Maybe I should’ve tried harder to get him in our group…”


It was dark, dark and humid, and they were both scared shitless as two of their classmates milled about just outside. The fear of getting caught caused Kris and Susie’s blood to run cold, who knew what would happen if they got found out. For one thing, Berdly would never shut up, but how would everyone else react if they found out Kris and Susie had been taking trips to the supply cabinet to fuck?

Kris’ heart pounded in his chest, sweat running down his brow as he tried to calm himself, keeping his trembling pants as under control as he could. And it seemed to be working at first, until Susie shifted her weight, the massive monster-cock jammed up his asshole shifted as well. 

“Mnh~!” A small whimper came from the lithe human as the shaft inside of him twitched, a purple claw shooting out to cover his mouth as a chill ran up his spine. Unable to help himself, he opened his maw wider, two claws slipping inside his mouth as he began to suck on them.

“Sh-shush! I don’t w-wanna get caught in here!” Susie’s tone was frantic, her chest pounding just as hard as the human currently impaled on her length. And although she was currently keeping Kris’ mouth clamped shut, this was the horniest she had ever been, especially as she felt his soft tongue curl around her clawtips, the smaller boy sucking voraciously on her digits. The prospect of being caught with all 14 inches of her shaft jammed deep inside of Kris made her want to bust a nut here and now, her softball-sized eggs throbbing in painful desire, furious at being denied the opportunity to empty their payload.

“Soo...Noelle. We’re all alone in here you know, perhaps we could...spend some time together~?”
“...Are you serious?”

Normally Susie would’ve had to stifle a laugh at the failed romance going on outside, but all of her strength was being put into not pounding Kris into a moaning mess right this instant. And for Kris, he was in another world, his mouth doing its own thing in nursing on Susie’s clawtips as his asshole nursed on the monster girl’s length. As if it being over a foot in length wasn’t enough, it was jam-packed with width, wider than a soda can, and every single centimeter was currently nestled within the boy, throbbing angrily against his prostate. Even now pre oozed from the tool currently stretching his hole, pooling up inside of his anus and sloshing about his inner walls.

“Berdly...I don’t thin-”
“Well you have to not be thinking to turn down a stud like, this~.”

It was getting to be too much for Susie, and for Kris, every second was agony as her ballsack twitched in desire, a growing urge to fertilize the hole right before it, and with every second Kris continued to drool from two ends, his saliva dripping down his chin as his neglected shaft stained the inside of his pants. The human’s poor prostate was in dire straights, utterly squashed by the fat cock currently embedded in his asshole. Unable to control himself any longer the human’s body reflexively squeezed around the invader, trying to keep some pressure off his beleaguered p-gland, but only succeeded in wringing out another squirt from the purple penis jammed inside it.

But that was enough for Susie, Kris’ hole teasing her already dangerously engorged shaft pushed her over the edge, and she couldn’t hold back anymore. Her free hand tightening its grip on Kris’ side, she jerked her hips back, the storage closet filling with a wet ‘shlhp~!’ as 4 inches of cock exited an already taxed hole. And before the human had any time to react, Susie thrust forward, re-sheathing her cock inside of Kris, her swollen testicles slapping against his own.

“Mngh~!!” Another mew of delight came from the male as his asshole found itself being punished once more with Susie’s presence, his ballsack suddenly spanked by an even heftier package. His eyes shot skyward as his hole shivered in delight, especially as Susie began to pull her length right back out again, his anus tightening around the shaft, unwilling to let go. 

But Kris’ hole had little choice, Susie’s cock called the shots in this relationship, and with utter ease the girl had pulled the base of her cock back from the human’s anal ring, only to slam it right back home once more. Her claws dug into Kris’ hip as she began to plunge her tool in and out of his asshole, the pre that had pooled up inside of the boy now oozing out with every thrust, dripping down Susie’s length only to get messily spread around Kris’ anus; strings of liquid connecting the pair even as Susie began to pull more and more of her length free from Kris’ asshole.

“Look. Berdly. This is not the time. We have no clue where Kris is!”
“Meh, it’s always Kris with you! He’s a human for heaven’s sake! Just look at him, no one in the classroom likes having him around!”

The voices outside grew louder and angrier, all while Kris’ moans of ecstasy grew as well, his tongue continuing to twirl around the two digits in his mouth as he hungrily suckled. It was all he could do beyond keep his knees straight as Susie pounded his asshole into submission, the monster getting increasingly into it. Back and forth her cock thrust into Kris’ asshole, the base of her shaft practically making out with his anus as the well-endowed girl’s tool refused to leave his rectum’s tight embrace. Susie grit her teeth as she picked up speed, lips curling as she fought to yank her swollen cockhead further from Kris’ depths just to slam it back inside as savagely as she could. And as the pair’s mating picked up in speed, the air became filled with the soft ‘thwack~! Thwack~! Thwack~!’ of ballsack meeting ballsack, Susie’s wrecking balls utterly battering Kris’ own coin purse. 

Every second it felt like the shaft spreading his asshole was getting even larger, more blood flowing to it, the veins running along it getting angrier, and Kris found himself losing more and more control. “Mnaah~!” Another moan came from the boy as Susie’s shaft slammed deep inside his hole, further than before, rougher than before, his prostate getting absolutely demolished. Each thrust got messier and stickier, his whorish hole holding onto Susie’s cock even tighter and tighter, slurping her shaft down greedily and then sticking to it like glue. And as Kris’ anus became sluttier by the second, the girl behind him slammed her hips harder against his fat rear, a primal urge within her driving her to breed the whore before her, regardless of the futility of the mating.

Up until now, the growing argument outside had made good cover for the two, Susie free to ramp up her aggression as Berdly stuck his foot deeper into his mouth. But as Susie reared back, her shaft almost entirely yanked free save for the fat head stuck behind Kris’ anal ring, she slammed back down, her pelvis meeting the boy’s rear in a loud smack, the boy-turned-cocksleeve shivering from head to toe before letting out a deep groan of desire even, regardless of his full mouth. “Mnyaaah~!”

“Do you know how pet-... D-did you hear that?”
“I-is someone in here with us? H-hello?”

Susie’s heart jumped to her throat, claws almost digging into Kris’ skin as the pair outside of the closet began to shuffle about and make noises. Her cock was once more buried to the root inside of Kris as he drooled around her clawtips, his hole still pulsing and writhing about her shaft. And he still continued to moan, not as loud mind you, but still moaning even as the voices outside grew closer and closer. Sweat dotted Susie’s brow as she rapidly looked about the dim supply closet, desperate for something to help while Kris only languidly squirmed on her shaft, too out of it to think about something other than the cock spearing him. And as his anus squeezed Susie’s length, her salvation came to hand.

Yanking her claw from Kris’ face, Susie using her freed hand with the one on Kris’ side to flip the boy over, bringing the couple face to face. Before Kris could make any noise, his fuck-drunk brain failing to catch up with the cock inside his hole suddenly doing a pirouette, Susie smashed her lips against his, pulling the human into a deep kiss. With his mouth stuffed with tongue, the boy’s moans were successfully muffled, though now far more frequent as Susie began to dominate his mouth just like his anus.

It was her first kiss, but as she began to pump her shaft back in and out of Kris, Susie felt herself shiver in delight. On both ends she was dominating the boy, and this knowledge alone made her ballsack throb in desire, she had to have more of him, she had to claim even more of the human. 

Pressing Kris’ back against the closet door, Susie began to fervently pound into his asshole, her lips pressing firmly against his own as she made him into a woman. She had done it to quiet the boy’s groans, but she had succeeded in awakening something else inside of her, and Susie’s head filled with nothing but the thought of mating with Kris, of filling him with nothing but her cum. Now it wasn’t only the boy moaning.

No longer having to focus on keeping strength in his legs to keep standing, Kris’ legs wound around Susie’s back as she thrust into him, his legs possessively locking around his lover. Wrapping his arms around her as well, Kris’ tongue tangled with Susie’s all while she continued to pummel his anus into the shape of her cock, no longer getting as deep as before, but able to pound her length into him with even more strength.

The muffled voices coming from outside grew more and more distant as the pair lost themselves to their base desires, all other noises drowned out save for their moans. Back and forth, Susie’s cockhead dragged against Kris’ prostate, no longer so deep that short thrusts would miss it, now every single thrust involved her wide head crushing it, making his hole squeeze even tighter around her shaft, feeding into a perverse loop of harder thrusts and a tighter hole. Locked together in this hot and sweaty mess, the pair felt their orgasms approaching, and as Kris tightened his hold on his lover, Susie began to pound faster and faster, no longer dragging her length out as far as possible, her hips turned into a blur as her ballsack swung back and forth.

It was Kris who came first, his thoroughly punished prostate triggering his orgasm, his equally wrecked package clenching as his shaft began to twitch and bounce. It would’ve been nice if he had the chance to at least free his cock from its confines, but that wasn’t on the boys mind as his head filled with pure white pleasure, his hole quivering and shaking around Susie’s cock, her lover moaning into her mouth. And thanks to his ongoing climax, Kris’ hole became vice-like around Susie’s swollen tool, giving her just enough time to slam her cock as deep as it could go inside of Kris, her own ballsack clenching and bouncing as it offloaded inside of the boy.

Her shaft felt like it had doubled in size within him as its urethra dilated with cum, Kris feeling every single pulse of monster jism inside his asshole, every pulse of the veins running along Susie’s swollen shaft. Their lips had never parted, but as the girl began to inseminate his anus, her tongue thrashed about his mouth, her eyes knit shut as she was overwhelmed by body numbing pleasure. She had jerked off before, but never before had she felt a release as strong as this, her balls practically aching as they shot more and more of her genetic payload deep within Kris. Tightening her grip, Susie ground the boy’s anus against her cock, making sure every shudder of her massive shaft sent her sperm as deep inside as it could go.

It was impossible for the two to tell how long it had been going on, Kris’ orgasm had long since ended but his belly continued to fill with a growing warmth as Susie pumped more of her sperm inside him. Being held like this, wrapped up in someone else’s arms as she defiled them only made the payoff even more ecstatic, Susie’s tool clenching and shuddering as she dredged more and more of her cum out through her ballsack and into Kris. Slowly, Kris felt a weight grow in his belly as Susie’s climax dragged on and on, a paunch beginning to develop, a bulge of nothing but the girl’s jism. It felt like she had truly managed to knock him up, something that made his already spent tool bounce up in appreciation for, adding to the stain within his pants.

But finally the monster girl’s orgasm began to approach its end, her pendulous ballsack clenching a few more times, as though to ensure every single drop was stuffed inside of Kris, before finally it was over. Slowly, the pair broke their kiss, each pulling ragged breaths of air, each one equally framed by sweat, and each one hungry for more.

“Y-you’re huff n-not that bad a-huff-a lay…” Susie squeezed out her words, unable to stop herself from panting intermittently. And just like always she got a non-response from Kris, the boy continuing to play the mute, save for the deep smile on his face, his cheeks a bright red from exhaustion and perhaps more than a bit of embarrassment. A look that made the still rather rude girl smile as well, “God, you’re such a fag~.” And go in for another kiss.


“No you gotta believe me! The supply closet is haunted!”
“...are you ok man? It’s like...just a room. Not even a big one.”
“You! Aren’t! Listening! Tell them about it Noelle! About how we went in there looking for Kris, and as I was con-...”
“I-I think...you were just hearing things...okay Berdly?”
