As Dave is pondering what to do, he hears the front door open downstairs. "Hey Dave, looks like they let you out early too for some reason." His younger brother Evan said. Evan was a little over a year younger than Dave, but had a similar immature body. Like Dave (before he was transformed), Evan only really had hair under his pits and his legs; Dave had a bad feeling he might be contagious and he didn't want to bring this fate upon his brother too!
"Yo Dave, you really need some deodorant, you smell like the school locker room - pretty rank." Evan said grimacing. Dave heard Evan start to come upstairs. Thinking quickly, Dave dashed into the bathroom and locked the door. Unbeknownst to Dave, his giant leaking cock dribbled precum in a small puddle in the carpet at the top of the stairs, and Evan stepped directly on it, making a quiet squishing noise. "Ew gross wet carpet" Evan thought, ignoring the implications of what just happened to him. "Dave I got out of school and don't have homework, how about we finish that co-op game real quick before I go hang out with friends?"
Dave's heart dropped. He promised his brother they were gonna finish their co-op playthrough together today, but in his current state it would prove difficult. However, Dave knew that if he beat the game with his brother quickly, Evan would leave for his friend's house, giving Dave time alone to sort things out. "Okay bro I'll be out in a bit." Dave scrambled and put on a hankerchief to hide his scruffy face, and slathered his entire body with stick deodorant before spraying himself with even more deodorant. Dave then wiped as much sweat off as he could and came out in a bathrobe to his brother's room.
Dave found Evan sitting on the couch starting up the game; Evan took off his shirt and socks. "Wow Dave, used a bit too much deodorant" Evan remarked. "Shut up and let's do this" Dave replied as he sat down next to Evan. "I'm feeling kinda sick - sore throat and all so that's why I'm dressed so funny." Dave said, excusing his appearance and disguise. "WHatever" Evan said, dismissing his brother's deeper voice and seemingly larger body as a result of his illness and outfit.
As they both began to finish the game, Dave was unknowingly giving off the jockish musk that infected him earlier. Evan was beginning to be affected by the musk and the cum stain he stepped in earlier, as Evan's feet grew to a size 10 and began to thicken with hair. Both boys did not notice the effects as they were too focused on completing this game.
