Mahito’s weight knocked the breath out of Junpei, landing hard on his stomach at the foot of the mattress. Paws scrabbled at Junpei’s hips and left long, stinging welts, and suddenly a hooked claw caught on the waistband of his boxers and tore them halfway down his thighs. An involuntary whimper escaped him when he felt the cool breeze of the air conditioner at his slick folds, but he didn’t have time to rethink just what the hell he was even doing before it was replaced with hot, panting breath over his holes.
“Wait,” He choked, nonsensically. He didn’t really want to stop; maybe Mahito could tell, because he gave no pause and no warning before lapping directly over his pussy. Junpei keened, he couldn’t help it. It was so humiliating, and yet—it felt so different from touching it by himself. So much better, so much filthier.
Mahito ate him out like he was his last meal. His tongue was long and the tip punched into him when he licked at him, sending a jolt through his legs at every repetition. Junpei squirmed, approaching climax at humiliating speeds. But just when he was on the precipice—Mahito stopped. Retracted his tongue from Junpei’s fluttering hole.
“N-No,” He whined. “Put it back. Please, Mahito…”
A lighthearted chuckle sent shivers through him. It felt wrong to hear such a human sound coming from… coming from a…
“Pathetic little human,” Mahito crooned. His mouth warbled around the words, like a human already transfigured. “Did it feel that good? Do you like getting fucked by dogs? You’re disgusting.”
Tears sprang to his eyes unexpectedly, even though he’d known this was coming.
“Slut,” Mahito continued. “You’d just let anything into your needy pussy, wouldn’t you? You want to get stuffed by dog cock so bad, don’t you?”
“Haah—“ Despite the sting in his chest, Junpei could practically feel himself dripping. His own fluids and Mahito’s dog saliva combining, melding into some disgusting concoction of lust and depravity. That’s what Junpei was—depraved. It was wrong. It felt so good. God, it felt good to be molested by an animal.
“I’m going to mount you,” Mahito hissed in his ear. “And I’m going to breed you.”
“Don’t—!” Junpei writhed under him, but the teeth at his throat stopped him from moving further. A wet snout prodded at the underside of his chin, reminding him just how vulnerable he was.
“Don’t pretend you don’t want this. Stupid whore. Stick your ass in the air before I tear your pretty throat open.”
Junpei raised his hips obligingly; the teeth retracted. The mattress shifted and dimpled as Mahito got re-situated over his conquest, two roughly furred limbs on either side, caging him in. Mahito jerked his hips forward, and something slimy rutted between the cleft of Junpei’s ass and tore a gasp from him.
“Humans are filthy,” Mahito chuckled. He thrust forward again, still missing the mark, but glancing over the rim of his pussy. “Go on, whore. Beg me for it.”
“Ahh—“ Junpei could hardly understand what he was saying, much less formulate a response, so dense was the haze of his arousal and humiliation. “You… huh…?”
“Tell me what you want, or I won’t give it to you.”
How cruel, to force Junpei inches out of this perfect haze just so he could put words to whatever this debauchery was.
“Please f-fuck me…” He whispered.
“Wrong.” Mahito teased the tip of his animal cock between Junpei’s folds. Another gush of slick rushed from him, Junpei felt Mahito wiggle their hips together so that he could coat himself in it.
Junpei struggled to think of what Mahito could possibly want him to say.
“Please, um, rape me, Mahito-san…”
“Better…” Mahito rocked them together, but got frustratingly no closer to penetrating him. “But I think a used cocksleeve like you can do better.”
Fuck, fuck! Junpei was losing his mind! “Please, please!” He tried desperately. “Rape me with your disgusting dog cock, Mahito-san. Please mount me a-and impregnate me, please! I’ll do anything, so please…!”
“Good boy!” Mahito said cheerfully, and fucked hard just slightly upwards, ignoring his pussy and popping fully into the vice of his unprepared ass in one violent motion. Junpei screamed.
“Mah-hito, stop…!” He hiccuped through his cries and Mahito’s animal thrusts. “Not there, it hurts! It hurts! Mahito, stop…!”
Mahito did not stop. It only seemed to make him move harder, more erratically, the swell of the wrongness of his penis stretching Junpei unbearably. He felt like he was going to tear in two—this wasn’t what they had agreed on, he hadn’t even stretched him!
Was he bleeding? He couldn’t tell, couldn’t even afford the mental capacity to reach behind and check. It was all he could do to keep breathing as the dog Mahito bore him down incessantly into the mattress, ignoring his cries, ignoring his pain, ignoring everything but his protestingly accommodating ass. He felt so unbelievably full when he was fucked into, and so hatefully empty when Mahito pulled back so he could push back in. It was awful. It was painful, it was scary.
“Stupid breeding bitch,” Mahito was spitting. “You bent over when I asked, you presented so pretty for me. I’m raping you, just like you wanted. You’re being raped by a dog. Isn’t it wonderful? Just like you wanted.”
“F-fuck!” Junpei wheezed when the next thrust went impossibly deeper. He could feel it in his pussy, he realized. Every time Mahito fucked him in his ass, he could feel it bulging in the walls of his pussy. It hurt so bad, it hurt, but why didn’t he want it to stop anymore? Why wasn’t he struggling? Why were the heaves of his sobs punctuated with whimpers and whines? Why, when he found his strength again, was he raising his hips higher, and wiggling them towards these awful jarring motions?
Mahito licked wetly into his ear, and Junpei moaned.
“S-Stop,” He tried, but it was only more embarrassing in juxtaposition with the wanting arch of his spine.
“I knew you’d like this.” Mahito accentuated his point with another sharp push into him. Junpei yelped involuntarily. His pussy was clenching around nothing—he was leaking like a faucet while being violated by a dog. Violated by his friend. He had begged for it, he was liking it! “Slut. Are you going to cum while being used? You’re despicable. It’s what I like most about you, you know. How awful you are.”
“Awful…?” Junpei could hardly breathe the word out, so forceful were Mahito’s movements. Mahito growled low, like an animal—like a dog.
“You’re awful, Junpei. I love it.”
“Ahh—“ It was far too much for Junpei’s brain. The ache was just barely subsiding, and he felt so stuffed when Mahito was inside him, dragging him back with their hips still pressed together. He was being used for Mahito’s sadistic purposes, and it felt good.
He liked it—he really liked it.
“Thank y-you…” He heard himself say.
Mahito hummed.
“I’m gonna cum inside you now,” He said conversationally. “I’ll let you choose. Your ass, or your pussy?”
“My ass, please cum in my ass,” Junpei begged. He was already being stretched loose, at least this way the pain would mostly subside and he could really enjoy this as much as he could.
“Understood. Pussy it is!”
“Wha—hah—!” Pain flared around his rim again as Mahito pulled abruptly free, then a completely different kind of pain as he forced himself downwards and forcefully breached Junpei’s twitching cunt. A gasp punched free of his lungs as he was stretched impossibly wide once again. When he inhaled, it formed in some sort of a cry, like a wounded animal, but he no longer had the strength to try and escape or even protest. It felt better now, being raped this way. He was already drenched in his own fluids from the rough fucking he’d just escaped from, so Mahito slipped in easily and non-abrasively, and when he went in his thickness hit places deep inside him that made Junpei tingle in his scalp and under the skin of his spine.
“I’m giving you my knot, Junpei.” Mahito huffed, finally sounded affected by any of this. “I’m going to impregnate you and keep you drunk on my cock every day. Be grateful.”
“Okay, okay, okay,” Junpei chanted, drool dripping from the corner of his mouth. His ass was going numb from the abuse, but it still managed to ache and sting, and still pulse with a heavy pleasure he couldn’t resist. “Thank you, thank you.”
Junpei could feel the slap of Mahito’s knot pounding insistently at his entrance. It was too big, it wasn’t going to fit. He wanted to say it, but found he couldn’t.
“Ah, having trouble speaking? You were being so noisy, I decided to remove your vocal cords for a while. Good dog toys should only squeak when bitten, you know?”
Panic flooded Junpei’s veins once again. He’d been subjected to so many sudden rushes of adrenaline already that it actually made him nauseous. He would have groaned, but all that came out was a heavy breath. Meanwhile, Mahito’s knot still swelled steadily bigger against him.
It’s not going to fit, it’s not going to fit, Junpei thought, almost joyful in his delirium. He’s going to tear me open!
Mahito fucked in viscously once, twice, then the knot popped through with a dull and wet sound, and Junpei couldn’t even scream. Cum painted his womb in spurts. It was warm and viscous, Junpei could feel how it settled in him, how it oozed with the erratic twitches of Mahito’s hips as he tried to coax the knot in even a fraction deeper. He could feel the swell of it moving inside him, how it sprayed more of Mahito’s filthy animal seed inside Junpei’s fragile body. It just kept going—more and more, fuller and fuller. Would it ever end? Junpei could only imagine he would be full forever after this. There was so much.
He didn’t know when Mahito had restored his voice, but he became distantly aware of his own whimpers and sobs. Was he crying? He couldn’t feel it, he couldn’t imagine why he would be. He felt so warm and so full. All the pain was waiting outside this bubble he encased himself in, and he could only comprehend the pleasure of purpose, the satisfaction of having been used by Mahito. He felt completely damned, finally. Irredeemable, untouchable. It was the sense of perfect completion in indulging in his depravity, complete euphoria. There truly was no greater purpose than to exist like this.
Some unknown amount of minutes or hours later, the knot finally deflated. Mahito pulled out without warning, and Junpei collapsed onto his side, mourning the loss, hardly noticing the pain that pulsed still deep inside him. He might have to get checked for tears later, Mahito was so rough with him. He didn’t care right now. He just wanted to keep all of the dog’s cum in his womb and fall asleep. But Mahito had other plans.
“Junpei.” A lick at his eyelid. When had he closed his eyes? Junpei struggled to meet Mahito’s gaze, still donning that eerie grayish dog form. He still had mismatched eyes like this, Junpei noticed blearily.
“Open your mouth. I’m going to fuck your throat too.”
Junpei could barely frown. He turned his head to the side and hoped the message would be received: no, I’m tired, I’m done for the day.
Mahito dragged his cock up Junpei’s skin, leaving a trail of wet and cold up his torso. He was still coated in himself. Over the barely-present swell of his pecs, over the tender skin of his throat. Mahito rested the tip on Junpei’s lips. Junpei didn’t open his mouth, but dregs of semen made their way onto his tongue anyway. It was disgusting. It was unlike anything Junpei had ever tasted before. Unthinkingly, he opened his mouth to spit, to retch. The moment Junpei’s lips parted, Mahito slipped in past the tip of his tongue, past his teeth, past his soft palate, deep into his throat.
Mahito did not move any slower this time. The swelled base of his cock pressed against the flat edge of Junpei’s teeth so hard he thought they might come loose. The uncontrolled motion of Mahito’s hips wrenched his nose this way and that, and he thought he tasted blood in the back of his nasal cavity for a lucid moment, until he was forced back into a fog of panic and pleasure. The taste was so awful, and Mahito was wedged deeply in his throat even without being able to squeeze his knot past the teeth. It was far too much for a novice like him. He tried to offset the building heave with noises and attempted turns to the side, but it was futile, Mahito just held him in place by the throat and fucked into his hand through the slick passage of Junpei’s esophagus.
Junpei couldn’t help it; he tried his damndest. But Mahito was going too fast and too hard, and one bad move triggered Junpei’s gag reflex. He hadn’t eaten much; most of what spewed around Mahito’s cock that choked him still as he vomited was only stomach acid.
Mahito’s pace finally slowed for the first time, and Junpei caught his breath. Or tried to, around the near-gore on his face that was tears, snot, vomit, blood, and semen.
“I should have turned that off,” Mahito said. He sounded apologetic in the way that one would be sorry for showing up late to cram school, in that, he didn’t sound sorry at all. “I’ll remember next time.”
And then he was in his throat again, uncaring of the way Junpei writhed under him or how he vomited once again, this time pitifully small.
Finally, finally, Mahito’s hips twitched unusually, and Junpei squeezed his eyes shut. Since Mahito couldn’t fit his knot through Junpei’s inexperienced jaw, he instead pulled out and rutted against Junpei’s bare stomach until he was spilling all over him again. The sheer amount made Junpei dizzy—did he still have that much inside of him? When Mahito was completely spent, he slunk off the edge of the bed and stretched back out to his complete humanoid form, still naked.
Junpei could hardly manage to keep his eyes open, but he noted distinctly that Mahito looked perfect. Milky smooth skin but for the mar of stitches, not a hair out of place. Pretty and perfectly presentable, and unaffected.
“I’d piss on you right now, if curses did that,” Mahito said. Junpei knew why—Mahito wanted to make him filthier.
“You can’t?” Junpei croaked.
Mahito was putting on his clothes without a care in the world. Junpei could do nothing to stop him. He couldn’t tell if he wanted to. Somehow, the thought of being abandoned after all this was despairing in such a pure sense that it would hurt to ruin it. It was perfect.
“Do you hate me?” Junpei blinked slowly. His eyes wouldn’t open back up all the way, so he decided to stop trying.
“I like you a lot, Junpei,” Mahito said. Junpei could hear him smile. “I like you most of all.”
Junpei had never before felt so understood. He let himself relax.
“Your mom will be home soon. Better lock your door. And clean yourself up, you look like you just got raped by a dog.” He laughed to himself a little. If he had the energy, Junpei might have laughed with him. He would have sobbed and begged for more. But Mahito may as well have been talking to himself now. Junpei heard him rummaging around and then stop. Several camera shutter sound effects went off in quick succession—Mahito was taking pictures of him on his own cell phone. How awful. Junpei would have to remember to thank him when he woke. More rummaging, one more camera shutter sound, but this one less tinny and more whirring. Junpei knew that sound, the Polaroid his mom got him for his birthday. It was a nice gift, but he didn’t have much use for physical photos. Until now, it seemed.
“This is the best you’ve ever looked.” Mahito stroked a hand down his leg. Junpei flinched several seconds too late. “I know you’ll take care of these pictures. You’ll put them to good use.”
Junpei would. He could already see himself four fingers deep in his cunt with his phone in the other hand.
“I’ll be back.” He didn’t say when; Junpei would still look forward to it so much it made him want to self-immolate. Mahito hesitated, and Junpei thought for an awful moment that he was going to apologize. But instead he just said this:
“You’re still too clean. Next time I’ll tear you open more.”
Such a simple lullaby was what finally carried Junpei to sleep.
