About 5 minutes into their game, Dave starts to notice the room is already starting to reek of his jockish musk. Dave's crotch is wet with his dripping pre-cum, but the robe he is wearing hides it from Evan. Dave pauses the game and moves to open a window to air out the odor. "Dave, it's hot enough inside the house, don't open the window you'll let out what cool air we have left." Evan told Dave. Dave noticed Evan's voice sounded a bit deeper than he remembered. Even more, Dave noticed Evan had a small patch of chest hair and barely visible treasure trail from his belly button. Dave remembered Evan having no body hair since last weekend when they went swimming. "Weird, Evan must have really matured recently" Dave thought to himself.
Dave decided not to open the window and sat back down, getting back to their game. As they kept playing, Evan's muscles felt a bit sore as they began to bulk up and harden with years of body building experience in the weight room. The odor in the room was getting worse and Evan began to notice he was starting to smell a bit bad. Evan kept his eyes on the game as he lifted a pit to smell it. It smelled far worse than any BO Evan had before and unbeknownst to Evan his pit was also much hairier and began to creep out from his pit when his arms were at his sides.
