Tyler sat in the corner of the steam room, alone until the skinny guy came in just a few minutes ago.
Trying to strike up a conversation he asked, “Warm enough for ya in here?”
Mark replied as he ran a hand across his sweat soaked chest, “Mmm, sure is, but it’s nice to settle down in here after a workout.” The energy of the chance working its way through his body.
“Yeah, I did as much as I could today. Need to get home to my little bro soon though.” Tyler responded as Mark groaned, his hand adjusting his towel covered crotch a little. “Uhh, don’t think this is that kind of gym dude.”
Mark replies his voice sounding a little deeper, “Sorry, guess it’s a little later than I though it was.”
“Well what does that have anything to do with jerking in the sauna?”
“Oh I was just adjusting; my balls were getting a little too big to be where they were.” Mark said with a smirk.
“Getting? What the fuck are you talking about?” Tyler said starting to get nervous.
Mark moans as dark stubble pushes out of his cheeks, his hair starting to darken as a dark trail of hairs starts to form overtop his towel. “Mmmm feels so gooood, hard to resist… I would say run, but it’s too late for that, sorry dude.” He says with an even more deepening voice.
“What the fuck is happening to you?!”
Mark stands up, his back to Tyler as he reaches for the lock on the door. His towel drops as turns the lock, giving Tyler view of his smooth white ass, skin suddenly tanning, dark hairs spreading across the cheeks.
“Common dude, let me out, I don’t need to be here.”
Mark just stands there, groaning as his back starts to widen, his lats jumping up. He turns back toward Tyler, a lust filled smirk on his completely different looking face. Mark’s pecs begin to balloon up, hairs quickly surrounding his nipples and spiraling out onto his chest.
“Christ! You… you’re changing!”
“Mmmm Hmmm, every full moon now… this one is looking to be extra good though.” Mark says looking down at his body, flexing his arms, watching his biceps grow.
“This… this one?! What the hell are you?”
“I’m a weregay of course.” Mark says reaching a big hand down and wrapping it around his cock. Tyler watches in horror as the foreskin quickly grows back, the meat in his hand getting thicker and longer.”
“A… weregay?”
Mark grunts as his stomach tightens and grows at the same time, a thick 6 pack now visible as he starts to move toward Tyler.
“Woah, what are you doing? Get away from me!” Tyler says as he tries to get up and move around Mark, but he is too big, wrapping his arms around Tyler and pulling him in for a kiss as his own towel falls to the floor.
“Stop! Let go! I’m no fag!”
“Mmm but you will be.” Mark says turning Tyler around pushing his dripping cock up against his ass, ready to thrust in.
“No, please!”
With that Mark thrust in, the big member surprisingly going in without much resistance due to his natural leaking pre lube. He pounds Tyler’s ass hard, his first fuck of the night always quick to satiate the overwhelming lust after a change.
“Oh fuck, owwwww!” Tyler screamed.
It only takes a few minutes before Mark’s big balls release their thick load up Tyler’s ass. He pulls out after a few seconds, giving Tyler a big kiss as he collapses to the bench. Mark picks up his towel, wrapping it around him as he heads out the door. “Off to the bar, maybe I will see you out soon.” He said in a cocky voice.
After a long while Tyler was finally able to compose himself, wondering what the fuck had just happened to him. He took a long hot shower in the locker room after he was sure Mark had gone.
Tyler silently made his way home, trying to comprehend.
