Simon organises a sexual playdate with an internet stranger...with a twist.


Oh look, some transformation. This was meant to be a quick lil' story but got away from me somewhat. I wrangled it back in line, and while it's not at ALL what I first envisioned (the werewolves really were supposed to DP the horse, and the moon was going to be involved, and there was going to be a huge focus on the "free refill" of the balls after a transform), I like this approach more.

Let me know what you think! Comments really help me decide what to write about in future.


I was sitting outside in the communal office recreation area, eating my lunch, when my phone moaned at me.

I paused, looking at it lying on the table in front of me. My heartbeat sped up. The moan was the sound I'd configured it to make when I got a notification from Sexlist. I'd posted an ad there some time ago, looking for a highly specific sort of fun. Every so often, I got a reply. I took my sandwich in my other hand and picked up the phone, chewing slowly as I read the message.

hey bud. saw ur ad. i'm totally into that. fucking hot. free tonight?

A thrill ran through my body, and my sandwich hovered in mid-air, forgotten, as my other hand tapped out a quick reply.

Hey stud. Yeah, tonight is perfect. Got any pics?

I put the phone down, my mind already thinking ahead to the end of the day. If I wrapped up around 5...then traffic...it was a Thursday, so lighter than usual...should be home around--

Another quiet moan from my phone; he responded quickly. I liked that. I grabbed the phone and opened the message. A photo this time: a tall, buff man in a leather jacket, holding a phone in front of his face, and looking into a mirror. His jacket hung open in front, showing off a fantastic physique. Broad pecs -- covered with a smattering of dark hair -- topped a flawless eight pack. Wide shoulders supported thick arms, with leather bands wound around the biceps. His free hand was tucked into the waistband of his pants, pulling it down enough to show off a teasing tuft of thick, black pubic hair. Below that -- pushing his leather trousers to their limit -- a large bulge drew the eye. I was hard in moments.

Trying not to let my fingers shake as desire and adrenaline flooded my system, I dropped my sandwich and took the phone in both hands, tapping more quickly.

You're fucking perfect stud. Do I get to see what's inside those pants?

He took longer to reply this time. Busy, or teasing? My money was on tease.

y_eah. later ;)_

He sent it along with another picture of himself: this one of a flexing arm. The hard bicep strained the leather band wound around it, and his armpit was musky and welcoming under it. The guy was hairy in all the right places, of course, and the sudden rush of saliva in my mouth had nothing to do with my lunch. The remaining half of the workday was immediately the longest stretch of time imaginable. Waiting patiently was not an option. I looked around; there were too many other people nearby, having their own breaks. I couldn't risk doing anything in public. I'd have to slum it.

Making a vague attempt to hide my boner with an egregiously spread hand, I got up and walked quickly back inside the building, heading to the bathrooms. A doddering old stoat stood inside, pissing into a urinal, but he didn't matter. I went into a stall and shut the door. Fully enclosed and somewhat soundproof, these little sanctuaries were the only place I knew of at work with any privacy...which was good, since I had my fly unzipped the moment after I slammed the bolt home. One hand held my phone, while the other stroked my cock. I flipped back and forth between the two pics he'd sent. Fucking hell he was hot. I looked alright for my age, but he clearly put in a lot more hours in the gym than I did. And that dick looked like a monster. I imagined it sliding inside a tight ass, how it would feel...

Trying to keep my groans soft, I snapped a picture of my hard cock, with a dribble of precum oozing from the tip. Look what you did to me.

The reply was instantaneous this time. nice dick man. u making mine excited too.

Another pic: close-up of his crotch, with the long outline of a penis clearly visible against the smooth leather. It was so tight, I could even make out that he was uncut. Saliva dripped onto my phone's screen from my lax mouth as I ogled him, disbelieving. Uncut, hairy stud dick. I moaned louder, no longer caring if the stoat outside heard me. I needed this sexy fucker so badly.

I tapped rapidly with one hand while I jerked off, my hand now coated with precum for lube. You think that monster's got what it takes to get the job done tonight? Rhetorical, of course. I simply wanted to see what he would say.

His reply included yet another picture: his face. I nearly nutted all over the wall of the stall. A trimmed beard, dark as his crotch fur, ran down his high cheekbones to meet under his chin. Arched eyebrows sat atop golden eyes that glittered under the lights of the room he was in. A cheeky, lopsided smirk showed off perfect white teeth, and a snazzy haircut completed the effect. He looked like he could get someone pregnant with merely a nod of his head.

The message with it was icing on the cake. u just leave the fucking to me, handsome. nobodys going home unsatisfied. where n when?

Hot, hung and cocky? Fuck yeah. He was exactly what I needed. I sent him my address and a time, and he sent me back a final tease: a shot of one exposed ass-cheek, with his thumb tugging down his pants. His ass was wonderfully hairy, too, and I could just about see a hint of his inviting crack. "Ah, fuck," I said breathily. I needed to be close to it, really badly. I was jerking fast now, and I could feel I'd be coming in seconds. It would be a big one.

But...I couldn't. Not yet. I wanted to save it for tonight. Forcing my hand to let go was agony, and I nearly threw it all to the wind and finished myself off. Somehow, I found the strength to resist. My dick stuck out from my fly: hard, needy, and purple as royalty. I let my phone clatter onto the lowered toilet seat and pressed both hands to either side of the stall, shutting my eyes and desperately trying to ignore my body's silent screams to finish what I started. I thought of unsexy things. Spreadsheets. Kettles. Theresa May.

By the time I'd softened enough to be able to squeeze my dick back inside my trousers, lunchtime was almost over. I sat on the toilet lid for a few minutes to see if my arousal would subside further, but the erectometer was pointed firmly at "uncomfortably chub" and wasn't moving. The mental picture of the dark, muscled stranger made it unlikely it would drop further. I sighed, and made my way back to my desk as quickly as I could; the last thing I needed was to be stopped for a chat now.

The remainder of the day was torturous. I couldn't focus on work, and waved away the few people who popped into my office to ask questions. I stared at my computer screen, unseeing, for a few minutes at a time. Then, I'd glance over to my phone and scroll through the stranger's pictures again. He was a fantastic beast. With a quick scan of the corridors outside through the glass walls, I'd let a hand give my crotch a quick squeeze, then release it before I pushed myself over the edge. I couldn't wait for the evening.

Time swaggered drunkenly on towards close of business.

Eventually, the day was over and I was heading home. At least in the privacy of my car, I could unzip my pants and let my dick out, stroking it whenever I was stopped at a traffic light. My balls were starting to hurt from the constant denial, and I savoured the pain. Not long now.

At a traffic light, I glanced across at the car next to me. The young driver was attractive, and I imagined him in the car with me, head in my lap, helping me deal with my problem. I must have stared a little too intently, because he gave me a strange look, and jumped the next light. Oh well. He hadn't been as hot as the stud from the net anyway.

I raced down my street at an inadvisable clip and pulled into my driveway. A strange car was already parked there, and I felt a tightening inside my belly as I hurried inside. He was here. It was happening.

Gloom had fallen outside, but indoors, all the lights were on. Yet, nobody seemed to be around. For a few seconds, I was unsure...and then there was a thud from upstairs, followed by a loud, high-pitched moan.

A stallion's voice. My boyfriend's voice.

My hands clenched and grew clammy. I stood frozen for a few moments, straining to hear for more sounds, simultaneously wishing to hear nothing, or hear everything. The stranger was here, then. And not only here: he was upstairs, right now, and he was fucking my boyfriend. That gorgeous, jacked stud had his dick -- a dick that was significantly bigger than mine -- buried in my guy, and was doubtless giving his asshole a fast, hard, sloppy fucking. Making him moan with his size and power and manliness.

I'd thought my dick hard before, but now it was paining me. I undid my belt and the top button of my trousers, and let it all out: prick jutting forward with the bulbous, purple head already drooling pre-cum, and my hairy ball sack hanging under it. I gave the balls a brief massage to try to ease their tension. It didn't help. Biting my lip to try to distract me from the needy ache in my loins -- not to mention the sounds of sex filtering down from upstairs -- I walked over to the drinks cabinet, and poured myself a small brandy. The liquid burned as I swallowed it with a shaking hand. A strange man was in my house, right now, filling my boyfriend's subby ass with his dick...and soon, his cum. I couldn't avoid it. I couldn't forget it. I had to face it.

I drained the last drops of alcohol and set the glass aside. I didn't bother doing up my pants as I climbed the stairs, letting my junk swing back and forth in front of me, sweeping the way clear. The bedroom was at the far end of the upper hall, and I had lots of time to take in the noises as I walked closer. I could hear the squeaking of the bed frame now, and the breathy sounds of my boyfriend's pleasure. He always made gorgeous sounds when he was being fucked. I could hear deeper grunts as well, brutish and unfamiliar. And when I stopped right outside the door, I could smell it, too. Even my weak human nose could pick up the tang of male rutting at this distance.

I took my erection in one hand, holding it tight, and pushed the bedroom door open.

The bed faced the door, which meant that I was greeted by the sight of a pert ass and a broad back, supported on thick, hairy legs. I recognised the one ass-cheek from the photos. The legs were spread wide, braced for support, and between them hung low balls. A trail of black hair -- thicker than that covering his legs -- ran right up the middle of the scrotum and along his taint, merging into furry, musky shadows between the ass-cheeks. Those cheeks clenched on every thrust he made, forming wonderfully curved dimples along the hips that begged for a face to nuzzle into them. And accompanying each thrust was a lascivious, wet noise, as long inches of dick slid into my stallion, hidden by the stranger's body.

The door had complained a little when I pushed it open, but the two of them didn't seem to notice. Or didn't care. I walked around, hand clenched almost painfully around my cock, and got a full view of the scene. Augustine, my boyfriend, was on all fours on the bed. His chubby stallion member hung under him, as hard as I'd ever seen it, and he turned a slack expression toward me as I came into view. He didn't even seem to recognise me. Spit dripped from his mouth in a thin, clear line, and sweat had matted his mane down across his neck and back. Only grunts and moans came from his mouth, and his beautiful dappled body was twisting and flexing against the sheets as the stranger fucked him from behind.

"Ohhhh..." Augustine made the first coherent noise I'd heard since I walked in. It seemed to be a struggle for him, as if he'd had to remember how to speak again from scratch. His head swayed a little as he looked at me with unfocused eyes. "S--Simon...he's so big..." A particularly hard thrust made his eyes close for a moment, his face a painting of ecstasy. "So...hhnnn...so thiick...oh, fuck, he's so much bigger than you, babe..." His head dropped down again, a few loose strands of mane flopping over his face.

His final words didn't even register properly, because at the mention of the visitor's size my eyes had snapped to him. The photos had been a shadow of what it was like to see him in person. He was...well, he was a stallion. Or as close to stallionhood as a man could hope to get. Strong hands gripped Augustine's hips hard enough to leave a mark. His coppery skin contrasted with my horse's grey hair, while the same dark hair I'd seen on his legs and butt also decorated his lower arms. Those arms thickened as they rode up to his chest, the biceps taut with the effort he was exerting to keep the stallion from going anywhere - not that he seemed to have any desire to leave. Thick pectorals with tight little nipples flexed and moved with his swaying motions...while down below, his massive fuckstick filled my boyfriend. Over, and over, and over again.

I met his eyes and stared mutely into them as he looked back at me, as collected as if he was waiting for a bus. He hadn't said a single word yet. The tiniest hint of a smile was on his mouth, but it was his nostrils that flexed and flared to pull in air. Like a wild animal. We looked at one another for a few moments. Me: middle-aged, in my sweaty, rumpled suit. Pants undone, gripping my cock like I'd die if I let go, watching a stranger have sex my boyfriend and doing nothing to stop him. He: younger, strong, dark and silent. Thrusting into willing stallion anus with leisurely strokes, as if he had all the time in the world. He did, though: I couldn't stop him. We both knew it. I was so clearly a lesser man than he was.

His eyes dipped down to my crotch for a second, and when they came back up, the hint of a smile from before blossomed into a feral grin. His white teeth glinted, and his red, red tongue slipped along them before he spoke.

"Still a pretty good cock, there, handsome," he said, and I whimpered. He spoke with all the authority of a lone wolf. A master in his domain. "But I got ya beat. Take a look."

He stopped fucking Augustine and took a half step back. Just enough to pull his cock out. Just enough to let the veiny, mouth-watering length of his manhood fall from my stallion's wet hole and hang like a pennant down his thigh. It was glistening with fluid, and the foreskin was tucked neatly behind a glans so swollen that it might be mistaken for a knot. The shaft was only a little less thick: I almost flinched at the thought of what it would do to an ass. Engorged with blood, the whole member was a deep purple, and proud veins snaked all across it, giving it the aspect of an ancient tree trunk.

Augustine had cried out the moment the massive penis was pulled out of him, and looked back at me now, over his shoulder, with needy eyes. "Please, Simon," he begged, "make him put it back in. I need it. I neeeed it, baby, please?"

The stranger cocked an eyebrow at me, waiting. His forearm was resting on Augustine's back, elbow towards the stallion's head, and his fingers toyed with my boyfriend's puffy hole. He teased his thumb around the swollen rim while his index finger slid inside, past the knuckle. When he tugged on it, my horse whimpered -- as if on command -- and pushed back to try and get more of the digit inside of him. I watched my boyfriend trying to satisfy himself against the most basic part of the stranger's magnificent body, and felt utterly worthless.

"The sub grows restless, handsome," the stranger said. If he had an idea of how this was making me feel inside, he didn't show it. "What's your answer?" He used his free hand to lift his amazing cock and point it at me, sliding his palm underneath it, back and forth. "Do I put this back inside your slut and finish the job...or should I go?"

I lowered my head, cock thrumming, stomach twisted in shame and horniness. I knew I should make him go. Augustine was my boyfriend, and I should be the one filling his rump and giving him pleasure. But they had both spoken, and both had made it clear what they wanted. So, with a thick voice and a dripping dick, I spoke.

"No. Stay. Please..." I gulped, and my legs felt weak. I tried again, hating the quaver in my tone. "Please fuck my boyfriend. Please satisfy him. Like...like he asked." Hot shame flooded my face, but I could hardly deny it. That stallion-sized cock was exactly what another stallion needed inside him. Not my boring todger.

The stranger made a satisfied sound, and pulled his finger out of Augustine, turning back to face him and lifting the tip of his cock to the entrance of his greedy anus. With a practised flick of his hips, the juicy length slid easily back inside my horse's loose and lubricated hole, and the stallion's head lifted up again in euphoria. "Oh yes, yessss..." His delight at being fucked by this stranger made me look away; my embarrassment was a physical thing in my throat. "Oh, fuck me harder, you beast, fill me up, give me your amazing dick, do it, do me, fuck my subby horsey ass..." The stranger slapped his hands to either side of my boyfriend's ass, and began to pick up the pace.

I could only stand and watch, masturbating my painfully hard cock and imagining how good it felt for Augustine to have the stranger's thick member driving into him. Better than I made him feel, clearly; the pleasure he was experiencing was plain to see on his beautiful face, and his moans were now joined by grunts from the man. The stranger's pupils had grown large, and his mouth was pulled into a rictus, as if he was trying to bare fangs he did not have. He and my horse swayed in unison, the wet slaps of flesh meeting flesh filling my ears as this dark guest gave me horns.

As his thrusting grew more frantic, his hands slipped further up Augustine's sides and his breathing grew shallower. In the brief gap between each inward push, I watched his balls. A little higher, every time. His mouth opened, and a growl formed, rising in volume and deepening rapidly into a fearful sound that seemed beyond the reach of a human throat. One hand pushed forward to grip Augustine's mane, pulling back on it to raise the horse's head. Augustine whinnied, and the stranger pulled himself forward suddenly, burying himself to the hilt in stallion asshole and holding himself there. I watched quivers running up and down that godlike body, and then he his growl escalated into a shivering roar, making Augustine squeal. The stranger was cumming.

When he was done, he sighed, and for a moment simply stood there, still inside my horse. When he let go of the stallion's mane, Augustine's head flopped forward, nickering softly. I could see that my boyfriend had sprayed his own seed onto the bed under him. Brought to climax by the cock of this usurper. Completing my cuckolding. The stranger turned to look at me, smirking, and met my eyes.

"You liked that?" he asked, looking down my hand. I broke his gaze quickly, rubbing my fingers against my palm to feel the slipperiness of the ejaculate. I hadn't been able to hold back; hearing him filling my boyfriend with stud sperm had pushed me over the edge and I'd cum into my cupped hand. The tension of my hours of blue-balling had sublimed into exquisite humiliation, though, and my orgasm had ended up as a weak affair. Most of it had run out of my palm, all down my trousers. "I showed your guy a proper good time, handsome," he continued, only then pulling out of Augustine. The sound of that fat meat exiting the stallion was wet and sexual. I was jealous. His thickness had begun to shrink already, but it still beat mine easily. "He'll think about me the next time you fuck, for sure." He glanced down at the horse anus he'd bred, cum oozing out of its stretched ring, and then back at me. "And so will you, I think?"

I said nothing. My failure as a partner was complete now, with another man's sperm pooling inside my partner. The stranger ran a finger around Augustine's ring and scooped up some cum, then walked closer to me and smeared it across my face. It had already cooled somewhat, and the hot blood that suffused my face made it feel cold against my skin. He streaked it from my eyebrow to my chin, fingertip lingering briefly on my lips to give me a taste. "I taste pretty good, huh?" he said, more softly. "I'm sure I don't need to tell you, though. Such a weak beta; you probably suck off all the guys at work, right? Hoping their alpha dicks will magically add up and give you the guts to stand up for your guy."

He tapped my nose with one finger, and I turned my head away. I didn't want to take this from him, but what could I do? "You listening, boy?" he asked, and snorted. "Shit...are both of you like this? That would be pretty fucking pathetic. Two betas in one body. Well..." He swept one arm to the side in a grand gesture that ended with him pointing at Augustine's hole, loose and inviting. "Perhaps soaking your dick in my cum will fix it, and you can stop being a failu--"

That was too much, at last. My arm swung around and my hand slapped him flat on the cheek, knocking his head aside. He raised his hand gingerly to the red welt I left behind, but when he turned back to face me, he was smiling. "There he is," he said, his voice half a growl. "This how you wanna do it, then?"

I grabbed his upper arm, and he grabbed mine in turn. He was stronger than me, but I was getting angry. We struggled against one another, eyes locked. I needed to get a jab in, make a mark on that too-perfect alpha attitude he exuded. "I didn't think you'd hold out this long," I said, tauntingly. "Maybe you need help?"

"If I need help," he replied, "I can just look at my load dripping out of your horse."

I growled in rage and pulled hard on his arm, tipping him a little. As he released my arm to regain his balance, I had just enough leverage to lift it up...and bite it. Hard. I felt his flesh squeeze between my flat human teeth, and something inside me awoke, and howled. I was close.

He swore and lurched backwards, slapping a hand to where my teeth had dug into his flesh. He held it between his knees, breath hissing, head down. "Aaaah! Shit! You...fucking..." His head flew up, and his eyes were different. More dangerous. More predatory. When he smiled at me, it took me a second to realise he didn't actually have fangs.

"Yeah," he hissed, "that'll do it..." His words were slurred, as if his tongue was too big for his mouth. When he straightened, he seemed stockier all of a sudden, and when he licked at his fingers to clean off a touch of the blood that my bite had drawn, they were thicker and hairier. He held it there, though; an impressive feat, given how hot his blood must be running right now. I was barely holding back myself. He must have sensed that, because he stepped into me and grabbed my balls. I could feel his strength as he squeezed hard enough to make me growl, and I tried to push him back with one hand. He paid no attention.

"C'mon then...let's see you," he said huskily, rolling my balls around like eggs. "Show me what you can do with a little more hair on these nuts..."

"You...first," I gasped in reply, trying desperately to resist. Edging made the switch so much better, but this guy was making that difficult. Plus, I was still dressed, and really didn't want to ruin another suit. His hand tightened a little more on my balls, and I shut my eyes, trying to think of unsexy things again. It didn't work this time: the only image that manifested was of Augustine being fucked, and the noises he'd made. And the moment I opened my eyes again, all I saw was the handsome face of this sex god -- with a couple differences. His fangs were down, and his eyes had sunk deeper. I groaned, watching his skin slowly vanish behind night-black fur. I even felt it tickling against my skin when he brought his mouth close to my ear.

"Let me see you first," he whispered, "and we can fuck your nice loose horsey together. At the same time." A hot tongue slapped against my ear and squirmed inside.

My self-control -- barely stable from the moment I'd seen his pictures earlier -- collapsed entirely. In an instant, my heartbeat went wild, and I could suddenly feel every vein in my body as my blood pressure skyrocketed. With the blood, came the energy: I felt strength growing in me like a weed, curling around my muscles and making them swell. My limbs began to scream as bones responded to the hormonal change, growing longer and thicker. I was a furnace, heat radiating from every part of my skin. My mind was a whirl, a chaotic mixture of logic and instinct as one self replaced another. The softer one stepping aside for the animal within.

The stranger let go of my balls and stepped back, giving me the space I needed. I huffed and snarled, my noises growing deeper as my larynx lengthened. The almost painful heat of my skin lessened as I erupted into hair, at last: a dense, chestnut coat that seemed to fold out of nothingness across my pale skin. I luxuriated in the sensation, and let my fangs drop in satisfaction. My jaw made a hideous cracking noise as it reformed, and it was suddenly as if I'd be dropped into an entirely different location as smells appeared from nowhere. There was the horny smell of Augustine, the sight of my transformation doubtless making him erect again; there, the smell of strange semen, dripping out of him. And there, almost overpowering both: the alien, heady scent of the other werewolf. He was still holding back, demonstrating remarkable restraint. I'd never managed to hold back while watching someone else turn; it was too erotic, too easy to imagine how good it would feel to do it yourself. And did it ever feel good.

I lifted my muzzle in a howl, stretching out my arms as the final changes happened. My clothes could only stretch so far, and seams ripped all over. I tore the scraps from my body with newly-extended claws, and arched backwards in agony when my tail extended from my spine. My paws were already there, their pads resting inside the remains of good leather shoes. Thick thighs supported the increased mass of my alternate form. I flicked my ears about, and then looked down at my crotch. It was always last with me, which I liked. It meant I could enjoy it with all of my increased senses.

The pink sausage of my human penis looked completely out of place emerging from a nest of dark brown hair, but only for a second. It twitched, and I growled in pleasure. It began to darken, soon reaching the same deep crimson as the stranger's fat dick, and then deepening more. I felt my ball sack lowering underneath it, even as it grew heavier, and hairier, refilled with lupine semen as a handy transformation bonus. The werewolf load put the other one to shame, naturally. But even when my sack was done growing, my cock was not.

It had grown out enough to not be able to stand straight anymore, and hung down heavily -- as unbending as the stranger's -- with a swollen base that expanded into a big knot. Eight, nine, ten inches. More. I could smell it, too: the faint and boring smell of human dick replaced by the thick, natural scent of wolf. There was a gentle tightening sensation as my sheath formed below the knot, and I was done.

I gripped my wonderful new cock in one paw and stroked, flexing my other arm to feel the muscles bulge, and bouncing up and down a little on my legs at the same time. I felt fucking incredible. When I was human, there was always a little voice in my head, asking me what I was going to do next. Making me plan ahead. Giving me anxiety. Making me feel...lesser. But this...this form was perfection. It was bigger, stronger, much better hung. It had more stamina, it was more aggressive...and it had its own, different voice inside. A louder one, that didn't care about schedules or organising or the complex human shame of seeing a stranger mating your partner. It was an animal voice that only ever said two words.

Fuck. Now.

My horse and the stranger were both staring at me. My stallion was regarding me with raw lust, but he made no move or sound to draw my attention. He'd had his fun, and he knew not to push for more. If he was lucky enough to attract my lupine attention, so be it...but if he tried to lure me, he'd regret it. A few faint scars on his back were reminder enough of that.

The stranger was giving me a more calculated look. His dick was swelling up again as his eyes flicked over my new form: arms, chest, legs, crotch. I swished my tail and growled, and he made a soft gasping noise. He couldn't help it, I knew. In that form, he was weaker. He was prey, and that realisation must have just landed. My improved vision could easily make out the sweat on his brow, and the beating of his heart might as well be a pair of timpani in the room with us. His scent was like an open book to my new senses, too. He was afraid. Cautious. And a little aroused.

I was simply an angry, horny werewolf.

Things were so much clearer in this form. The answers were obvious. This stranger had offered me my own stallion as a lure to make me transform, but he'd failed to follow through himself. I did warn people in my ad that they shouldn't delay their transformation. But, he had looked at my human side -- my weak side -- and made a very great error of judgement. For why would I go for the second-hand prey, the been-there-done-that stallion...when this fresh, untouched male was here for the taking?

Like a loosened rubber band, I exploded into motion, hurling myself across the room. I was gratified to see actual terror splash across the stranger's face as my form barrelled into his, and we slammed against the wall together. Augustine gave a shrill scream of fear: this was a deviation from the usual activities. I didn't care. The stranger's dazed expression was trying to focus on my face, suddenly a mere couple inches away from his; his fangs and fur had vanished as he lost focus on his transformation. He must be in shock. That was good; I wanted this to hurt.

I snorted a single hot breath into his face. "I don't feel like horse tonight," I snarled. "I think I'll have...man."

I lifted him up against the wall effortlessly -- my paws digging into his armpits -- until his face was at the same level as mine. He was gabbling something or other, trying to make me stop, but when did a wolf ever care what its prey had to say? I put an end to his irrelevant begging with a single massive thrust forward, which drove more than half of my thick lupine cock into his soft asshole in one fell motion.

As my cock surged into him, I lifted my head and gave a bestial howl of pleasure, drowning out his commensurate scream of pain. I met his eyes again -- so wide and afraid now, the shrunken yellow pupils were all but lost in the sclera -- and chuckled throatily.

"You're so tight, stud," I jeered. "Don't often get fucked like this?"

Maybe he replied; I didn't take notice. Instead, I pressed forward, my body trapping him against the wall as my cock drove ever deeper inside. There was a heightened level of sensitivity to everything for a short while after a transform, and his ass felt like warm silk, wrapping around me in folds and stroking luxuriantly. When my knot bumped up against him, I gave a juddering growl and paused. My muzzle was pressing against his cheek, and I could hear the whimpered yelps he made every time I moved inside him. I was thicker in this form than he was as a human, and even a prepared ass would take a beating from my dick. I'd given him no time at all.

I licked along his jawline and over his beautiful cheekbones as I pulled out and thrust back in, eliciting another gasp of pain. His hands were pressing hard against my muscled chest, trying to push me away; there was no chance of that. He would remain trapped until I was done using him. Back my hips moved, and in again, twelve red inches of tapered werewolf cock burying themselves inside him. I growled, and he moaned. Again. Again. My balls swayed on each inward motion, knocking into his legs. Let him feel that. Let him have an inkling of the volume of werewolf spunk roiling inside.

The pace picked up, and I let my nose drop down to his neck. His head moved aside a little, to make space, and I grinned. "That's it," I said, nuzzling into his neck, and his groan of response was not one of pain, but desire. He'd come around. They always did, when the fucking started. I stopped for a moment after pulling out, just to see if he'd do what I expected...

"D--don't stop..." he whispered, and my growled response was victorious.

I slammed forward, pressing every inch of my dick -- and the very top of my knot -- into him. My body rumbled, and the hands pressed to my straining chest contracted into fists, gripping bunches of my fur. My violent thrusts continued, and my snorted breaths growing hotter. He was working with me now: I could feel his ass tightening around my member as best it could. I snarled and spread my legs further, giving my hips more traction, and railed his sweet, silky ass for everything I was worth. Drool ran from between my clenched teeth and down his back as I rested my head on his shoulder. I was still holding him up with my own strength, but his muscles had untensed, and his hands were squeezing my pecs as I fucked him. I pushed back a little more from him, to give my hips more space to move in. His own dick was hard again, smearing my abs with pre-cum as it slid back and forth. The air was full of the smell of horny man and sweaty wolf.

"Harder...harder!" His hands tightened on my nipples, urging me on with his voice and his hands and his tensed ass.

I gave a loud growl and let my claws dig into him a little for grip. My knot was hammering against his anus, but it simply wouldn't fit. He was crying out again now, but in pleasure, every time I hilted into him. Our sounds of exertion merged with the slapping noises of knot and balls against skin. I desperately wanted to knot him, but humans were so small. If only he'd completed his transform earlier, when I'd bitten him...

The idea and the execution were concurrent. Pushing in hard to press my knot tightly against his hole, I turned my head a little, moving it back -- and biting down hard on his shoulder. He cried out in a mixture of pain and pleasure, and I felt his anus spasming around my cock as I pressed into him as fiercely as I could. His cry grew higher, going on and on...and then warbled, and became a growl. I bit a little harder, feeling the skin break under one tooth and a brief squirt of hot blood in my mouth set my predator instincts on fire. The iron taste of him, the closeness of my orgasm, the absurdly intense feeling of being inside him as his body transformed...I dug my nails harder into him, feeling the hair forming over his skin and broke my bite on his shoulder to thrust my muzzle against his. Our tongues lunged at one another, fighting for control as our bodies slid against one another: one firm, one in flux. As his muscles bulged outward and night-dark fur replaced sweaty human skin, his asshole grew too. And as it expanded, I broke our kiss, gave a howl of joy and a final rough push, and knotted him.

His paws unclenched from my chest and slid over my shoulders, grasping them and pulling me towards him just as he lifted his own muzzle to roar in climax. Werewolf asshole squeezed tight around my invading cock, and I howled in tandem with his roar, my furred balls finally getting the opportunity to empty their load. He came a second before me, and a spurt of his hot and slimy load smacked into the underside of my muzzle. I quickly lowered my open muzzle to receive the rest, even as I pumped my own seed deep into him. He was hanging from my arms now, his legs too weak with pleasure to support him. Slack-jawed, tongue lolling, he whimpered endlessly as the dual stimulation of both orgasms pummelled his lupine body. His fountaining cum slowed to thicker, shorter surges that hit our chests and bellies as his powerfully erect cock slid about between us, before finally dribbling to a stop. My nose was full of the smell of him -- literally and figuratively. One of the shots had gone right up there. I snorted it out.

His eyes reopened and regarded me lazily. A droplet of cum was oozing down the side of his muzzle, and I lapped it up cheekily. He tasted musky and male, and I murred. Every slight adjustment of my body now tugged on the obscenely turgid knot I had inside him, and made him grunt happily. I smiled and gave him another sloppy kiss.

"Not how you thought tonight would go, right?" I asked. He shook his head and linked his paws behind my neck. I adjusted my stance to better support him, and he growled, mistaking my intention.

"Don't you fucking dare pull out of me now, handsome..."

I snorted. "No chance of that. Your ass is fucking hot, stud." I pushed in a fraction deeper, to prove that. Cum squeezed out of him with a wet sound, finding a hair-thin gap around my tightly-fitting prick. He sighed and let his head fall back against the wall, simply enjoying the tie.

It was only when he said, "What about you guy?" that I remembered Augustine. My head turned. The stallion was sitting with his back to the wall, jerking himself off with one hand and fingering himself with the other. He looked lustfully at the two of us, and gasped when the stranger snarled at him. Two sets of predatory eyes regarded the helpless, willing horse. I lifted a paw and raised one finger slowly, in a circle. Turn around.

Augustine shivered with anticipation, and got back onto all fours, with raised tail.
