Felix tries to control his breathing, clutching at his chest as he carefully treads through the forest. He had run away as soon as the chase had begun, going off the trail in the hopes it would make him harder to track. The preternaturally quiet atmosphere fills him with a sense of dread and foreboding—even the birds and insects seem to have left him to his fate, having all gone quiet and into hiding, most likely scared away by the giant predator currently chasing him. If only he hadn’t chosen this weekend to go camping, maybe he’d still be safe at home with his boyfriend, cuddling and binging episodes of ‘The Witcher’.
Tired, he slumps against a tree, letting out a quiet breath of air. Maybe he’s dreaming—maybe he’s still asleep in his sleeping bag inside his tent.
“Come out, little human,” a deep, raspy voice calls out tauntingly, gruff as it reverberates throughout the woods. “I can smell your fear, you know…”
Felix’s pulse races at the sound of a twig snapping in the vicinity, and he pushes himself off the tree trunk, sprinting in the opposite direction of whatever’s hunting him.
“I’m not going to hurt you, little lamb,” the voice coos almost fondly, and it would sound tender if not for the animalistic quality layered over it. “I just want a little… taste.”
Gasping, Felix continues running, heart thudding heavily with the sounds of something truly monstrous chasing after him echoing in his ears. He knows he won’t be able to outrun it forever, but he just needs to make it out of the woods—to find other humans that can protect him.
He knows it’s over for him as soon as he trips, scraping his hands on the rough soil beneath his feet. The creature easily pounces on him, pinning him beneath its weight, rendering him immobile and struggling to breathe.
“Thought you could run away from me, hm?” the thing growls, its breath almost scalding hot in his ear. He feels the itch of something hairy against the side of his face, reminding him of the time he cuddled with his friend Hyunjin’s dog.
Felix whimpers, pain radiating from the impact to his hands and knees, unable to form words to beg for mercy. All he can do is lie there, limp and pliant, and hope that it loses interest in him when it realizes that he isn’t going to do anything.
“Oh, Felix…” Felix’s blood goes cold at the mention of his name. Is that—? “You look so delicious like this, so tempting.”
He feels the rumble of the creature’s dark laughter against his back, his own hair rising in response to it.
“Are you surprised? This is what you asked for, after all,” the creature continues speaking. “I was the perfect human boyfriend for you, but you didn’t want that… You asked for a beast, so, a beast you’ll get.”
“Chan…” Felix wheezes out, terror surging through him. He feels a sense of nausea and disorientation as he’s roughly flipped onto his back before he finds himself gazing up at the monstrous creature above him. “No, please…!”
He had always known theoretically that Chan wasn’t human—that he’s actually some type of eldritch being, unconfined to any singular form, immortal and beyond Felix’s actual comprehension—but he fell for him anyway, hard and fast.
When Chan had explained to him what he was, the example he had given was the Norse God Loki, who had apparently been him. He was the being that ancient civilizations had worshiped as the Trickster God, and tales of his numerous forms were widespread.
Of course, the first thing Felix had asked for was if they could fuck like that.
“No?” Chan echoes Felix’s plea, claws poking Felix’s skin through the thin fabric of his night clothes. “Aren’t you being ungrateful? I’m just giving you what you wanted, and now you’re denying it?”
“Please,” Felix pleads, but he’s not sure exactly what he’s pleading for. He's only ever known Chan’s normal human facade—his boyfriend is so incredibly handsome, more like a statue sculpted from the likeness of a God than an actual man, even if Chan himself insists that Felix is even more ethereal.
But right now, none of that Chan can be seen anymore. His entire body has completely shifted into something akin to stories of werewolves, unrecognizable with how it's covered in fur as dark as midnight but still vaguely humanoid in stature. His face has transformed, features elongated into the shape of a muzzle, black beady eyes staring at him with hunger and lust, lips drawn up into a feral smile revealing sharp rows of serrated teeth.
Now that Felix is paying attention, he realizes that his boyfriend’s cock is pressed up against him. It’s huge—he can’t look away from it, the way it’s dripping precum, staining his clothes, along with the fact that there’s a knot located at the base of the already thick cock. It’s at least thrice the size of Chan’s already sizable human cock…
Heat floods through his body, followed by shame and revulsion. He can’t help his instinctive reaction to the thought of something so big going inside him.
“You want this,” Chan accuses, dragging his claws through Felix’s clothes, shredding them apart and leaving behind raised welts on his skin. He grips Felix’s chin with his fingers, the tip of his claws pricking him but not drawing blood, and licks the side of his face with his rough tongue. “I thought about stopping, but I can smell your arousal. How much you want me… and in this beastly form, too.”
Felix wants to turn his head away in humiliation, but Chan keeps him in place, so he averts his gaze instead. He’s embarrassed that he’s so turned on, that this is a confirmation that maybe humans are a bit too normal for him.
“Oh, don’t worry,” Chan purrs, spreading Felix’s legs wide open, revealing the plain metal plug in his ass that he had put in earlier. “There’s no one here to see you taken by a beast like some common whore. Unless that’s what you want…”
Ass clenching around the plug, Felix imagines someone coming across him being fucked wide open by Chan and used like a toy. His cock is fully hard by now, stiff against his abs with precum beading at the tip.
“I’m—I’m afraid…”
It’s true—he is afraid.
Not because of Chan or his form, but because he’s not sure he can actually take Chan’s cock all the way in. He’s scared that it’ll change him so fundamentally that he can never go back to how he was before all this.
Something in Chan’s manner seems to soften at his admission, even as his cock feels like it's searing Felix’s skin on contact. “I’m going to ruin you for humans, little lamb. You’ll never want a normal cock after this.”
And then Felix is flipped back onto his stomach, ass held up in the air as the plug is slowly plucked from his hole, only to be fucked back in after stretching his rim at the thickest part. He moans low in his throat, craving the fullness that only a cock can give him.
Chan continues playing with him for a few minutes, teasing him enough that he’s on the verge of begging. After he finally pulls the plug out completely, he places the tip of his cock at Felix’s entrance without pushing in.
“Rather small, isn’t it?” he remarks unhelpfully, as though Felix isn’t acutely aware of the difference in sizes. He withdraws his cock, and Felix feels a gust of air against his puckered hole. “I have just the thing to open you up.”
Felix keens as something thick and slimy pushes all the way into him in one go, not even giving him a moment of reprieve before it’s thrusting in and out of him, massaging his insides. It somehow gets bigger—bigger than Chan’s human cock—expanding until he feels like he’s never going to close back up after his boyfriend is done with him.
“Oh, you’re just so tasty, I could devour you whole,” Chan praises enthusiastically like he’s eating a michelin-star meal. It just barely registers to Felix that he has Chan’s tongue up his ass, the points of Chan’s razor-sharp teeth on his back and stomach, but he can’t think about the very real fear of being eaten alive with how full he is.
“Fu—fuck!” Felix squeaks out, involuntarily clenching around Chan as the tongue stimulates his prostate, curling and squirming inside him unlike anything he’s ever felt before. He forgets everything else—the burning in his eyes from sweat and tears, his scraped palms, the uncomfortable feel of dirt under his body—all that matters is how good Chan’s making him feel.
“Your body was made for this,” he vaguely hears Chan say, before it’s drowned out by more pressure, stretching wider than he ever thought he was capable of. A sob rips through him as sharp pain forces him to tighten up around the tongue that’s getting bigger and bigger.
“Ch… Chan!” Felix tries to crawl away from the sensation. His fingers dig into the dirt as he attempts to drag his body away, but Chan’s teeth hold him in place, possibly drawing blood too if the groan coming from Chan is any indicator.
All of a sudden, Chan’s tongue disappears from inside only for him to feel it licking around his body like he’s being sampled. Then comes the feeling of something big and hot against his gaping hole, that can only be Chan’s monster cock.
Felix holds his breath as Chan tries to push it in, pained noises escaping him with every agonizing millimeter. It hurts, so much, but he wants to find out how it feels to be fucked by a real monster—by something so inhuman it changes the trajectory of his entire life.
Finally, the crown of Chan’s tip pops in, nestling against his prostate, causing him to confuse pain and pleasure until it becomes a singular sensation. It feels so much bigger than the tongue, even if it’s only the tip, but he doesn’t get more than a moment’s respite, Chan pushing his cock in deeper, stealing away his breath.
Chan stops with a ferocious growl. “Gods, you’re so tight…”
“Is…” Felix swallows, trying to dislodge the lump that had formed in his throat with how deep Chan is. “Is it fully in…?” He can’t even muster up the strength to look back at Chan, nevermind take stock of himself.
“Not even halfway in, my precious,” Chan says fondly, furred hands—paws?—stroking Felix’s body all over before resting underneath him, cupping his stomach. “I can already feel myself here…”
Felix looks down in disbelief, noticing just how much he’s bulging from the size of Chan’s length in him. He unconsciously clenches around Chan but realizes that he’s too loose—he can’t feel the muscle anymore, all he can feel is Chan, filling up his every crevice and pressing against his prostate.
Chan lifts him up with a single hand, getting to his feet as he keeps Felix impaled on his cock. “I could destroy you like this. But I won’t—oh, no—I can think of much better things to do…” Slowly, he pulls Felix off his cock until only the tip remains, before slamming him all the way back and dragging out a loud scream from his boyfriend.
“Chan!” His voice could almost be mistaken for anguish if not for the fact that his cum is all over Chan’s fur as well as the forest floor. He pants, tears running down his face, and screams again as Chan starts using him like a fleshlight.
“If only your friends could see you like this, little lamb,” Chan purrs darkly, ripping out painfully overstimulated cries from Felix’s throat with ease. He could probably walk around with Felix speared on his cock like a sleeve all day. “All fucked out on my cock, completely ravaged.”
Wet, ragged sobs echo throughout the forest. Felix has never been this hard in his life, his cock so spent and yet, still rock solid. He’s leaking so much it looks like he’s pissing cum, his prostate constantly abused by Chan’s massive cock.
“Nooo,” Felix protests weakly with a moan, hanging limp on Chan’s cock. He can’t think anymore, brain filled with fog and body wrung dry like a wet towel.
“Can’t wait to knot you and fill you up,” Chan taunts, the base of his cock growing bigger with every thrust, forcing Felix’s hole open even wider. “Gonna make your stomach round with my pups. You’ll be so beautiful.”
Chan’s going to knot him.
“No, please, please—no! Chan!”
The begging has no effect at all, Chan doesn’t even slow down no matter how pathetically Felix pleads with him. “You know what to say if you really want me to stop, little lamb.”
Felix does know—the words are right there at the tip of his tongue. He could say it, end it all right here, but…
“Mmfuck! No, I shouldn’t like this—!” he cries out, eyes rolling to the back of his head as torrential pleasure overwhelms him.
Chan, the monster that he is, doesn’t care. He fucks Felix with no regard for his comfort, taking his body like it already belongs to him, claws leaving marks on his skin.
There’s no one to save Felix from him, not this deep within the woods.
“Oh, little lamb,” Chan coos, stroking Felix’s side like a beloved pet, “You shouldn’t lie to yourself. At least your body is honest.”
Chan speaks the truth—Felix can’t stop the tears from dripping down his cheeks, knowing that he’s actually enjoying being fucked so carelessly by an ancient monster.
Felix can deny it all he wants, but he knows that deep down, all he wants is to be fucked like this.
A sudden bulge threatening to rip Felix apart makes itself known at the base of Chan’s cock. He whimpers, half scared and half turned on, hoping that it isn’t what he thinks it is.
“Can you feel that?” Chan slows down, letting Felix truly feel himself opening up around the inflation. “That’s my knot, and soon it’ll all be in you.”
Felix’s eyes widen at the feeling of his hole being stretched to its limits. “No, please, Chan—I can’t, you’re going to hurt me!” he sobs, thrashing his body in an attempt to escape.
Unfortunately for him, his body is firmly stuck on Chan’s cock, supported only by a single hand as the knot slowly but surely forces its way into him, sending sparks of pain and pleasure up his spine.
God, Felix is never going to be the same after this.
“Yes, you can,” Chan refutes him easily, “Look at how well you’re taking my knot, your body was meant for this.”
Felix squeals as Chan fully sheathes his cock—knot and all—inside him, cumming just from the knowledge that he took it all. His ability to think is slipping, giving way to the instinctual need for more.
More. Moremoremore.
“More? I knew you’d see it my way,” Chan crows triumphantly, slamming his knot repeatedly into Felix.
“Yes! Fuck, so good! Chan!”
Unable to do anything else, Felix vocalizes his pleasure—repeatedly and enthusiastically—his body wracked with dry orgasm after dry orgasm, completely milked dry. Is this how broodmares feel? Or is he just that much of a slut for a monster breeding him?
“Yeah, fuck me—oh!” Felix gasps loudly as Chan’s knot suddenly pops, filling him with an endless flood of warmth and irrevocably tainting him forever as it locks him with his captor. Chan’s cum bloats his stomach, so much so he can almost taste it in his throat, making him look pregnant, so full from the sheer volume of it that it leaks from where they’re connected.
A sudden lethargy overcomes him then, his eyelids becoming so heavy that he can’t even keep them open. Chan won’t mind if he closes his eyes for a few moments, right?
Felix doesn’t know how much time has passed since he closed his eyes, but he’s still impaled on Chan’s length when he wakes up. His entire lower half feels sore enough that it hurts to even shift his weight. Chan’s claws are carding through his hair, careful enough not to nick him.
“Lix?” Chan’s voice rumbles through him. “How are you feeling?”
Felix’s mouth tastes and feels like sandpaper. “Like you blew my back out.”
Chan barks out a laugh. “Anything else?”
“I don’t think I’m going to close up ever again,” Felix says after taking stock of himself. “You’re fucking huge.”
“You’ll be fine,” Chan assures him, “I held back on the size.”
If the size of three XL bad dragon dildos combined into one was holding back, then Felix shudders to think of just how big Chan can grow—
“I want to see my cum flowing out of you,” Chan says, his voice barely above a growl.
Felix flushes, but nods. Chan doesn’t pull out just yet, opting to shift back to his human form, his cock shrinking back to regular proportions and slipping out on its own as thick globs of cum ooze out of Felix’s ass, seeping into the ground.
“Fuck…” Chan breathes out, the lust clear on his face. He easily pushes his entire fist into Felix’s ass, coaxing more of his cum out while Felix moans shakily.
Chan is unbothered by the mess, absorbing it all into his body within the blink of an eye the way he normally does. His ability to absorb anything always fills Felix with a sense of awe watching things disappear into Chan’s skin without a single trace left behind.
“Take me home now?” Felix smiles up at Chan, glad to see his human visage. “I don’t think I can walk…”
Chan grins, Felix’s favorite dimples appearing on his cheeks as he easily lifts Felix up into his arms. “Yeah, I’ll have us back in no time.”
