“Hey, you’re gonna be late for practice if you don’t get up!”

Kyle knocked on the door to his dorm, trying to wake up his roommate, who even in the afternoon sun lazed about on his bed, seeming rather sluggish for a star player on the football team.

“I’m comin’, I’m comin’.”

Kyle waited impatiently for his roommate, and more recently his boyfriend, to get dressed so that they could walk to the field together. At first the two couldn’t have seemed more different. Kyle was studious, reserved, a classic introvert who always wore clean, pressed sweaters and kept his side of the room tidy, while Chuck was an eccentric, extroverted jock whose sweat-soaked jerseys could always be found piled up around his bed. But being roommates, they naturally got to know one another, and with each interaction their fondness for one another grew. Kyle would help Chuck with his homework, and Chuck would help him socialize at parties. Kyle got Chuck into some good books, Chuck taught him how to throw a football. More and more they got to know the intimate details of each other’s lives, and before long, the two began to feel themselves longing to be more than just mere friends. Just before the end of their first year together, a red-faced Chuck confessed his love for his roommate, and from there their relationship quickly grew romantic. Their love for each other was as strong as ever when they entered their second year of college, and they spent nearly every waking moment of their days together. Kyle particularly loved watching his tall, muscled partner play football. Though he’d never be able to admit it to him, something about seeing him running around in that bulky uniform soaked in sweat always seemed to get his blood pumping. The usually clean, well-kempt blonde blushed with embarrassment every time he watched Chuck disappear into the locker room after practice, thinking about the possibility of him just maybe skipping his shower for once.

But for now, the only thing on his mind was making sure Chuck wasn’t late. Hurried by Kyle’s knocking, Chuck threw on some clothes and stepped out into the hall before promptly giving his boyfriend a kiss on the forehead.

“You’re looking particularly cute today,” Chuck teased, smirking as he watched his partner try to hide his blush.

“A simple hello would be fine…”

“Aww, but then how am I gonna see that even cuter blush of yours?”

“Let’s just go! You’re already late as it is.”

“Okay, okay.” Chuck smiled as he took his partner’s hand. “Let’s go.”

~~~

Kyle watched eagerly from the stands as Chuck took to the field and began his warm-up drills, quickly working up a sweat in the hot August sun. Chuck’s team was set to scrimmage against another team from the area, but even by the time his warm-ups ended, he was already feeling exhausted. He wanted to sit out this match, but as he looked to the stands and saw Kyle’s attentive, smiling face aimed right at him, he knew it would only disappoint his partner. The scrimmage began, and for the most part he kept up, but as the evening progressed he only found himself growing more and more tired. His breathing grew concerningly heavy as he jogged down the field to set up for the fourth quarter, sweat dripping down his forehead and soaking into his uniform. He looked over at Kyle once again, who only smiled and waved at him, and he felt relieved that his partner seemed not to really notice how much he was struggling. But in truth, Kyle was very well aware of Chuck’s capabilities, and he knew that something was off. This wasn’t the first time either. Every month or so, Chuck would seemingly have an off day where he just couldn’t keep up with everything like usual. It wasn’t too serious, and even Chuck’s coach didn’t really notice, but Kyle could tell. As he watched his partner struggle to get through the fourth quarter, he started thinking about how Chuck would suspiciously excuse himself from the dorm on the nights of all of those games, not returning until the afternoon of the next day. Kyle hadn’t really thought anything of it before, but now that he saw the connection to Chuck’s poor performance, his mind started to race with ideas. He tried his best to block out the terrible thought that Chuck could be cheating on him, but the thoughts only grew more intrusive as the scrimmage neared its end. What if he was sneaking out to see someone else every night he disappeared? And what if he was only sluggish in football because he was distracted thinking about this mysterious other?

“No! He wouldn’t!” Kyle mistakenly shouted aloud, turning a few heads. He covered his face with his hands and blushed with embarrassment.

“What’s wrong with me?” he thought to himself. “Thinking he’d be cheating on me?” His mind wandered again. “But then, where does he keep going?...”

Chuck brushed the sweat off his forehead as the end of the fourth quarter came, but the game was a tie, and the coaches agreed to play some overtime. Chuck wanted nothing more than a cold shower, but if he stopped playing now, Kyle would start to get suspicious that something was wrong, or even worse be disappointed that he couldn’t last through the whole game. So he pressed on, struggling more and more to keep up with the pace of the game until even the coach began to consider pulling him out. The sun disappeared over the horizon as the game seemed to stalemate forever, and Chuck felt as though he was going to pass out when finally a time out was called, and his coach declared that the game would have to end in a draw so that the other team could catch their bus home.

Kyle approached his partner, who was bent over still catching his breath even as the others left to the locker room.

“You were great out there, Chuck!” he lied.

“Th-... thanks…” Chuck stepped away a bit, not wanting Kyle to see how tired and sweaty he was, but it was more obvious than he thought. Even at a distance, Kyle could easily detect his boyfriend’s musk, and his cock twitched ever so slightly in his shorts as he took a deep breath of the strong, aphrodisiacal aroma. He blushed a bit as he felt himself getting turned on, watching as Chuck finally stood up straight and looked up at the sky, realizing for the first time how late it had gotten.

“Whoa, what time is it?”

“It’s almost midnight. That game ran really long, I’m sure you need a break. Why don’t you sit with me a bit before going to get changed?” Kyle wasn’t sure if he asked the question for his sake or for Chuck’s.

“Almost midnight!? Oh crap… I-... I gotta go… right now…” Without even so much as a goodbye, Chuck turned and started to head off the field, neither walking to the locker rooms nor in the direction of their dorm.

“Wait, where are you going!?” Kyle chased after him.

“I-... I just…” Chuck stopped walking for a second, seemingly trying to come up with some excuse that he didn’t have. “I… I just gotta go get some air for a bit!” he shouted before starting to run towards the wooded side of town away from the rest of the campus.

Once again Kyle’s mind began to race. He didn’t like this mysterious behavior of Chuck’s, and he was done guessing at what it meant.

“I’m serious, Chuck!” he shouted as he started chasing after him. “I’m your boyfriend, I deserve to know where you’re going!”

“Don’t worry about it!” Chuck replied. It… it doesn’t concern you!”

“But I’m worried about you! About… us! You’re not…” Kyle slowed to a stop and paused before finishing his sentence. “...seeing someone else… are you?”

Chuck stopped in place. He turned to look at Kyle, immediately noticing that his partner had begun to tear up. His heart sank.

“You don’t… actually think that, do you?”

“I-... I’m sorry…” Kyle rubbed the tears from his eyes. “I just… I don’t know what to think! You won’t tell me what’s wrong…”

Chuck approached Kyle slowly before hugging him tightly.

“I’m sorry… I just can’t tell you…”

Kyle continued wiping away tears as Chuck held him, refusing to weaken his grip as the seconds passed.

“But that doesn’t mean I don’t love you. I’ve always loved you, and only you.”

He kissed his forehead as the clouds concealing the full moon drifted away, its soft glow illuminating their embrace. And then it hit him.

“ GAH! ” Chuck yelped in pain, breaking off from Kyle and clutching his stomach. “ Shit , too late… Kyle… you have to- nnnngh fuck …”

“Chuck! What’s wrong!? What do I have to do?”

“You have to… ohhhh fuuuuuck … you have to… get out of here…”

The sound of crackling bones began to fill the air as Chuck dropped to his knees.

“Chuck, what’s happening!? What’s that sound? Do you need me to call an ambulance?”

“N- no… just- ughhh … go!”

But Kyle wouldn’t budge. He couldn’t just abandon his partner when he was in pain like this. Instead, he knelt down beside him and started rubbing his back softly, hoping that he could somehow soothe his ailing partner. But as he glided his hand back and forth across Chuck’s jersey, he sensed what felt like Chuck’s spine starting to press out against it. He lifted Chuck’s jersey and looked on with shock as Chuck’s spine pushed out against his skin, forming rigid mounds along the center of his back.

“Wh-... what’s happening to you!?”

Chuck didn’t respond but only groaned in pain between fast, heavy breaths, sweat dripping from his body as it started to heat up. While kneeling beside his partner, Kyle was struck by Chuck’s intense musk, which seemed nearly twice as strong as before. Refusing to leave his boyfriend’s side, he incidentally huffed in more and more of it, and felt his cock starting to tent his pants. Now was no time for him to get horny, but he couldn’t help it. Chuck’s musk was too strong, and too good, to ignore. Kyle’s mind started to fog as he felt himself getting worked up, while Chuck’s body began to tremble as the jock’s transformation progressed.

Chuck winced and gritted his teeth as his fingers started to stretch out in front of him, inching longer and longer as his nails began to elongate, quickly sharpening into pointed claws that grew thicker with each passing second. He looked on as hair grew in along the backs of his hands before beginning to spread up his arms. He then felt his cock starting to shift underneath his jockstrap, not only beginning to grow longer but also getting aroused from the changes affecting him. Though his transformation was painful, it was simultaneously euphoric, and he urged it on as he too started to succumb to his arousal.

“ Nnngh fuck yes … More…”

“Chuck…” Kyle looked over at his partner’s hands, not realizing that he had started softly rubbing his bulge, his partner’s musk heightening his arousal to the point of no return. “You’re changing…”

“ FUCK! It feels so huff … good…”

Chuck felt his feet start to press up against the fronts of his shoes, stretching longer and thickening with muscle while thick, sharp claws extended from each of his toes. The sound of Chuck’s cleats popping and splitting open filled the air as his feet outgrew them, the bones quickly snapping into a digitigrade position. Chuck moaned lewdly, already on the verge of climax even though his transformation had just barely begun. Kyle continued looking on with worry but also curiosity and a hint of lust as his partner changed, his back starting to pull the fabric of his jersey tight against his skin, accentuating his distended spine and now swelling back muscles.

“And you’re getting… bigger…”

“I’m… nnnnnnngh … I’m sorry I didn’t tell you sooner, Kyle… I’m- agh … I’m…”

“A werewolf…” Kyle finished his sentence for him as he noticed the full moon shining down on them.

“I just… I just didn’t want- ah … to scare you away…”

“It’s okay, Chuck. I understand now. You don’t need to explain yourself anymore.”

“But-... you’ll…” Chuck’s words trailed off as his transformation progressed, his feet growing thicker and hairier as his legs began to bulk up. His knee and thigh pads pressed tightly up against his pants, pushed out by the growing muscles beneath them. Kyle continued huffing his partner’s musk, noticing that he was fully erect as he continued to rub his bulge but was now too horny to care. He saw Chuck’s much bigger 8” cock sticking out between his growing legs as it pressed out into his pants, accompanied by a wet spot of leaking pre. His arousal mounted as he watched his boyfriend continue leaking more and more pre into his uniform, his cock growing noticeably bigger beneath his jockstrap and stretching out his tightening pants further. Kyle started jerking himself off through his clothes as his partner’s transformation, combined with his scent that only seemed to be growing more powerful, sent his libido soaring.

Chuck turned and saw his partner jerking off through his clothes.

“You’re… you’re getting off to this?... You don’t nngh … you don’t think I’m a freak?”

“Of course not… I huff … I’ve been afraid to admit it before, but…” He saw his partner’s arms beginning to bulge, Chuck’s shoulder pads pressing firmly out against his jersey. “Your bulging muscles, and…” He took a deep huff of Chuck’s scent. “That powerful musk of yours, your body being drenched in sweat… I can hardly control myself around it all…”

“You… like those things? But you’re always huff … so tidy…”

“I know… I’m a bit embarrassed to admit it huff … but I guess while we’re sharing secrets…” he smiled at Chuck as his uniform started to rip apart, unable to contain his growing bulk any longer.

“In that case…” Chuck huffed excitedly, his voice becoming deeper and sounding slightly more animalistic as he turned and pinned Kyle to the ground. Kyle moaned at the sight of his partner’s uniform splitting right down the middle, torn in half by his enormous, swelling pecs. Sweat dripped off of Chuck’s chest onto Kyle’s shirt as hair began to sprout in the crevice between the two massive slabs of meat, quickly overtaking them and spreading down towards his thickening abs.

“I can’t take it anymore… Fuck me, Chuck” He rubbed his bulge eagerly, feeling as he spurted pre into his briefs.

“ Huffff …” Chuck’s voice continued to deepen as his teeth began to elongate, growing into sharp fangs that both scared and aroused Kyle. “Are you sure, Kyle? I’m not sure huff … if I’ll be able to control huff … myself…”

“I want it, Chuck. I need it. I need that swelling cock of yours.”

As if on cue, Chuck’s manhood surged through his pants, tearing them wide open and pulling his jockstrap tighter and tighter before snapping it off, leaving his nearly foot-long, impossibly thick staff exposed. Pre spilled onto the grass beneath the two as it stretched and thickened, the sight of it sending Kyle’s arousal through the roof. He motioned for Chuck to release his grip on him before promptly turned himself over and pulling down his pants just enough to expose his tight yet plump ass.

“The truth is huff … I always prep it before your matches… I was huff … holding out hope you’d skip your shower one day.” He took another deep breath of Chuck’s intoxicating musk. “I guess my wish came true…” he smiled.

“I’m sorry, Kyle…” Chuck replied. “I’ll make up for it all right now…”

Chuck’s face began to shift into a muzzle as he lined up his throbbing cock with Kyle’s hole. Hair spread down the sides of his face as his ears began to stretch up the side of head, all while his cock started to grow more lupine, the tip tapering off into a point while the base grew a thick, round knot ready to be buried in his boyfriend’s ass. He wasted no time teasing his partner’s hole and quickly slid it deep inside, his shoulder pads popping off as his delts continued to swell, his thick, bulging arms once again holding down Kyle to keep him from shifting around. Kyle’s moans were music to Chuck’s wolflike ears, which stretched longer as his face continued to push out into a wolf-like muzzle. The sound of cracking bones grew louder as his teeth stretched longer and hair continued to grow in over more and more of his body. The rest of his uniform was increasingly torn apart as he finally sank his knot into Kyle’s tight ass, the sensation causing both of them to instantaneously start cumming.

“Oh fuck huff … yes huff … more huff … please Chuck huff … don’t stop…” Kyle’s lewd begging only made Chuck cum harder as his swelling feet ripped out of the rest of his cleats, his swelling legs tearing more and more holes in his pants until finally it was torn off completely, leaving just the tattered remains of his jersey and undershirt, which quickly succumbed to his growing musculature.

“ Fuck Kyle huff … You take my cock so well huff … even when I’m a wolf…” Chuck couldn’t stop cumming even well past the end of his partner’s climax. His balls swelled bigger than they’d ever grown before as they filled with lupine seed which was quickly rushed into Kyle’s overstretched ass. Kyle felt his stomach starting to fill up as Chuck came what felt like a dozen human loads into him and kept going, his balls churning with more and more seed. He came a second time as his balls struggled to keep up with his arousal, which demanded a climax as long and as powerful as Chuck’s but had no werewolf genes to assist them. Still, he moaned constantly as Chuck pounded him with ever-increasing force, the scent of sex only heightening the pair’s arousal further. Chuck grunted as his spine began to press out into a tail, all while the rest of his exposed skin became covered in a dense layer of fur, with extra thick layers over his chest, armpits, and groin that empowered his already impossibly strong musk.

It took several minutes of intense mating before Chuck’s orgasm gave out. Now completely transformed into a werewolf, he collapsed onto the ground beside Kyle to catch his breath. Kyle cuddled up against his partner’s warm, fur-covered body, smiling as he felt up his enormous, bulging muscles. Chuck was now close to eight feet tall, and his enormous 13” cock lay strewn over his leg as it spurted out the last remnants of his orgasm, his massive balls aching from overuse. He turned towards Kyle and pulled him in close to his body, hugging him tightly once again, but this time as a massive, alpha werewolf. He had planned to keep this part of himself hidden from Kyle forever, but by a strange twist of fate, he had revealed himself to be exactly what Kyle secretly desired most: an absolute beast with the scent and cock to prove it.

The two almost drifted off to sleep before being startled by the sound of the football team heading out of the locker room.

“Shit, I don’t want anyone else to see me,” Chuck said as he got back up.

“How about we take this somewhere more private?” Kyle responded, catching Chuck off guard since he was usually more shy when talking about sex. Chuck smiled pleasantly, his new wolf body having seemingly awoken something new in his partner. Chuck followed Kyle as he got up and headed off into the nearby woods. As they proceeded through the trees, Kyle inspected his partner's body, and asked him about how he came to be a werewolf.

“It was a few years ago, in high school. I was out hiking and got attacked by another one. The bite healed up okay, but by the next full moon, this was my new reality. I wish I could say I’ve enjoyed being a werewolf… The transformations feel good and all, but it’s been nothing but trouble having to disappear every full moon and hide out in the woods and all…”

Kyle was reminded of his accusation from earlier.

“I’m… I’m sorry I confronted you about that, Chuck. I just…”

“Don’t worry about that now,” Chuck cut him off. “You were in the right to be suspicious. I should have told you, I was just worried that it would scare you off, like I said…”

“Then I should have told you how much I love big, bestial bodies like yours.”

Kyle rubbed up against his partner’s shaft, staring lewdly at the beastly manhood as the two proceeded deeper into the woods. He was sort of shocked his ass was able to take such a big knot even though he was lubed up, and internally he patted himself off the back for managing it, his training for taking Chuck having paid off nicely.

As the two proceeded into a clearing sufficiently deep in the woods, Kyle’s mind was already running wild with lewd ideas, and Chuck was starting to get pent up again already. Chuck sat up against a tree and motioned for his partner to sit on his lap. Kyle sat straddling his cock as he looked up at him, not fully realizing just how much bigger his partner had become until now. He planted a kiss on his muzzle before rubbing his partner’s staff experimentally, forcing out moans from Chuck as his arousal began to climb.

“I wonder…” Kyle began before starting to experiment with his partner’s wolf form, which seemed surprisingly soft and cuddly despite his sharp teeth and claws. Chuck began panting as Kyle started rubbing his stomach, his tail beginning to wag like a dog as Kyle started giving him full-on belly rubs. He reached up and rubbed behind Chuck’s ears, leaving Chuck panting even more heavily, almost unable to handle the sensation.

“K- Kyle! Stop… It’s too m-... oh yeahhhh that’s the spot…”

Kyle smiled almost maliciously as he continued playing with his werewolf boyfriend’s surprisingly vulnerable body.

“You’re just like a dog!” he teased.

Chuck let out a deep, bestial growl as his partner’s teasing got him more and more worked up, a desire to go all out on Kyle and remind him of his dominance beginning to well up inside of him. It grew in parallel with his arousal as Kyle slid back and forth on his cock while continuing to explore his partner’s body. Chuck began to feel himself start to work up a sweat again as he struggled to prevent his more bestial side from taking over. but it grew harder and harder to resist as he only became hornier with each passing second, pre already dripping from his rapidly stiffening cock.

Kyle too was getting hornier by the second, his asshole twitching as it seemed to sense the swelling mass underneath him. As he started to feel up Chuck’s arm, he leaned in closer to his armpit, the musk quickly flooding into his nostrils and sending a quick burst of pre flooding into his briefs.

“Wow, you smell really good, Chuck. Would you…” Kyle blushed with embarrassment, but Chuck only smirked before raising his arms and pressing Kyle’s head directly into his armpit. Kyle’s cock quickly straightened out into full mast, spurting out more and more pre as he repeatedly huffed the werewolf’s unbelievably strong, almost pungent musk. Chuck moaned as he felt Kyle’s warm, wet tongue sliding over his pits as he began to lick them, collecting every last drop of salty sweat off of Chuck’s fur.

“Now who’s the dog, lapping at my sweat like it’s a water bowl!” Chuck laughed as he continued to hold Kyle in his pit, letting him huff as much of his bestial scent as he wanted. As Kyle’s arousal soared, it became clear to Chuck from the twitching of his legs and ass that he was ready to be fucked once more. He pulled Kyle up over him as his cock hardened fully, standing straight up like a spear directly below his partner’s ass. The bestial side of him took over as he quickly sank his boyfriend down onto it and quickly began thrusting, his cock sinking deeper and deeper into Kyle’s ass as it loosened up. Kyle cried out in a mix of pain and pleasure as Chuck fucked him, his furry body continuing to drip with musky sweat. Both of them were already leaking pre heavily, and Chuck could physically feel his balls filling up with seed as he bred Kyle‘s ass faster and faster.

“Nnngh… Fuck me harder, Chuck!”

“That’s right, keep begging for your alpha to fuck you like the cub you are!” Chuck’s low, animalistic voice became more prominent as his dominant, bestial side took over, the alpha inside of him ready to claim Kyle as its prey.

“Ha- ahh… Harder!” Kyle begged. “Knot me, Chuck! I’m already so close…”

With Chuck’s meaty paw, he gripped Kyle’s cock tightly and started furiously jerking him off just as he sank his knot into his ass, bottoming out completely.

“Better not cum, pup!” he commanded, wanting his omega to prove its loyalty.

“But huff … you’re rubbing it so fast! I- huff … I can’t hold it in!”

“Cum and your alpha may just have to find stronger prey to breed!”

Kyle obeyed the werewolf’s commands, trying with all his might to hold in the cum that swirled around in his aching balls, desperately wanting to be released. Chuck slid up the tree as he continued thrusting upwards, eventually finding himself standing as he continued to plow away at his partner’s tight, pre-soaked ass. As the two became drunk off of the werewolf’s increasingly powerful musk, which spread like a fog throughout the hot, humid air around them, Chuck utilized every last drop of power in his legs to fuck his partner at full force, his thrusts quickly inching Kyle ever closer to the climax that became harder and harder to resist. And then finally…

“Gonna… CUMMM!!!!!! ”

It was Chuck. The beast unloaded his massive, pent-up load into Kyle’s ass, his stomach rapidly bulging as it swelled with an unending flood of hot, thick seed. Feeling Chuck’s cum rush into his ass, Kyle could no longer hold back his orgasm, and he unloaded several spurts of his own seed onto Chuck’s chest and abs. He quickly leaned in to lick them up as Chuck continued stuffing him with cum. It was as if his balls had somehow gotten even more full than they were the first time. He came for thirty seconds, a minute, two, and still he kept going until finally Kyle’s stomach could no longer hold any more. He pulled out of Kyle and placed him over top of his cock once again as he finished cumming. Kyle moaned as he licked up the sweat and cum interspersed throughout Chuck’s fur, feeling as pulses of cum continuously rushed out through the beast’s enormous cock beneath him. For minute after minute Chuck came at full force before finally collapsing back down against the tree, completely out of breath and drenched in sweat. His scent was stronger than ever, and both his and Kyle’s cocks continued to throb long after their climaxes finished, each breath they took like a sucker punch of pungent musk that kept their arousal high.

“You outlasted me Kyle huff … Your alpha is impressed huff …” Chuck smirked, his bestial side not quite fading away completely but calming back down as he felt his awareness beginning to return.

“Well I’m not just anyone huff … I’m your boyfriend huff … so I’ll last as long as you need me to!”

Kyle leaned in and kissed Chuck deeply. He struggled a bit to adapt to his boyfriend’s muzzle before finally finding the right positioning, and as the pair’s tongues became interlocked Chuck felt more strongly than ever that Kyle was perfect for him. He held the kiss for as long as he could, his lungs that were starving for oxygen taking a backseat to the love he wanted, no, needed, to express for his partner in that instant. When the two finally broke away, Kyle cuddled up against Chuck’s pecs and closed his eyes, smiling as he drifted off to sleep on the pillow of Chuck’s fur. Chuck rubbed his back softly as he looked up at the night sky, seeing the full moon shining brightly over top of him. And for the first time since he was cursed, the sight of it made him smile.

~~~

Kyle laid out fresh sheets over his bed, carefully tucking them around the corners of his mattress like usual, leaving his side of the dorm perfectly neat and organized. He turned to look at Chuck, who was lying down on his unmade bed reading a book that Kyle had recommended to him.

“Looks like another full moon again tonight.” Kyle smiled.

Chuck closed his book and looked over at Kyle. “Yep, looks like it. You sure you can handle being my pup for another night?”

He walked over to Kyle’s side of the room and climbed over top of him before giving him a kiss, his cock already hardening at the thought of the events to come.

“Anything for my alpha.”
