Alpha TF - Tumblr Posts

I am fond of you Derek turning into a more muscular and/or hairy guy if that's the kind of request you were looking for? Love your stuff though regardless it's hot and well done.

It all began the morning after Derek had assumed his new Alpha title. Stiles had slept over, cuddling up next to his boyfriend when he'd jolted up awake as soon as his hands had brushed up against something unfamiliar.

"What...?" he trailed off, his eyes wide at his boyfriend's chest that he usually used as a pillow.

"Hm?" Derek sleepily yawned, wondering what his smaller boyfriend was panicking about.

"Der," Stiles mused, "your chest. It's... really hairy."

The werewolf cocked his eyebrow up at his boyfriend, running a hand over his pecs. Sure enough, the werewolf's previously smooth chest was now covered with black hairs. They spread out over his pecs, running down across his stomach before connecting to his bush. The hairs curled and looked thick enough to where one might've guessed that Derek had always been rather hirsute. His pert nipples poked through the dusting of hairs, looking hard. Plus, Stiles hadn't noticed it initially, but Derek's square jaw was also covered by a thick beard that looked like it'd take weeks for a guy to grow... not just a few hours.

Derek's eyebrows knitted together as he ran his hands over his hairy chest, his heart starting to race. However, just as soon as the worry began to trickle in, it disappeared.

His face smoothed out and he yawned loudly, gently placing a hand on Stiles's head to pat it back down to his now hairy chest.

Stiles wanted to argue, confused over both his boyfriend's sudden change and different attitude. He knew that Derek should've been freaking out and wondering what was happening to him, but instead his boyfriend acted like everything was normal.

He tried to ignore it, but as Stiles rested his head back down onto Derek's chest, something about the way he had to crane his neck alerted the human to something else.

"Derek!" he gasped loudly, sitting back up and tearing the covers away from his boyfriend. "You're... bigger!"

His boyfriend had always had a pretty toned physique, but now it looked as if Derek's chiseled pecs were now significantly larger and much more plump than they should've been. Without the covers over him, Stiles could also see that it wasn't just Derek's chest that had grown larger. His boyfriend's arms seemed to have doubled in size, looking thick and powerful as he lied on the bed. Even his legs were larger, his quads pressing tightly together and shoving his bulge (which seemed to stretch out his underwear more than usual) out in front.

And of course, every single larger muscle was covered in dark, manly hair.

"Stiles," Derek groaned, going so far as to roll his eyes, "everything is fine. I feel fine, there's nothing to worry about--"

He was interrupted when his phone alarm beeped, letting him know that he had to get out of bed, making him frown.

With a groan, Derek rolled his hairy bulk out of bed, the frame squeaking much more than it usually did as he moved. His heavy footsteps thudded over towards the dresser. As he walked, Derek noted how odd it felt to have his thighs rolling over one another, and how awkward it was to have his muscular arms resting at a ninety degree angle atop his flaring lats.

Stiles watched in disbelief as Derek nonchalantly attempted to get dressed in his normal clothes.

"Damn," Derek growled as he examined himself in the mirror. With his new bulk, none of his clothes fit him anymore. He couldn't get any of his jeans up past his massive quads, having to throw on a large pair of sweats that used to be baggy on him. Now, the material was skintight, showing off his meaty glutes and enormous package in front. The t-shirt he'd grabbed barely wrapped around his torso, ending above his navel. It had torn significantly across his large muscletits, showing off the hairy cleavage that he now possessed. There were two large bumps on the front from where his larger, nubby nipples poked against the thin cotton.

Stiles watched as Derek paled in the mirror, his beard-framed mouth opening like he was about to voice his concerns, but again, Derek seemed to instantly relax. He shrugged his broadened shoulders.

"I think my clothes shrunk in the wash," he chuckled, gesturing down at his hairy muscles.

"Derek!" Stiles cried, throwing his hands up in the air. "It's not the wash, it's you! You've turned into a hairy bodybuilder!" As crazy (or crazier) as it seemed, Stiles could've sworn that he'd watched Derek's hairy pecs balloon out a few more inches in those few seconds.

Derek took one last look at himself in the mirror, seeing how large and imposing he looked with his incredibly large, round muscles and the thick, masculine hair that coated them. He couldn't help but smirk back at his shocked boyfriend, flexing a large, hairy bicep. As his massive muscle bulged to the size of a bowling ball, the tight sleeves of the t-shirt burst apart.

"I'm not a bodybuilder," Derek smiled at his boyfriend, giving him a playful wink. "I'm the Alpha."
