Mike was just about to head into the shower, grinning and thinking he was becoming such a stud for Rachel to enjoy...when he was disrupted by a phone call of all things. Grimacing and rolling his eyes, Mike - still naked and not even bothering to get dressed - took the call. He was not any more pleased when it was his Sensei instead of his girlfriend.
"Mike, the SES drinks are not safe. You have to---"
"I don't "have to" do anything, man. I'm gonna be such a fucking stud for Rachel thanks to that drink." Mike was speaking on impulse, faster than he could even think, and would've apologized if only for the sudden static on the other end. He chuckled and figured the old man was jealous. He was just JEALOUS that Mike was so incredibly buff now, with such a long cock, and feeling so good. When he was so old and...and had a bad phone!
Mike looked around and saw one of the mirrors in the room, smirking and seeing an idea forming for him. He'd always wanted a bit more size, but now he actually had it. He was the biggest guy on any given mat, he knew it. Long as he kept his intake up. He couldn't wait to fuck his girlfriend. He stroked his cock a few more times, shivering with how good it felt.
He started to outright flex and pose for the mirror and himself, enjoying the newfound size and strength he possessed. Never before had he seen these overwhelming striations and muscular developments.
He wanted to really enjoy each and every one before heading to the shower...
