You walk out of the bathroom, still dripping with water. Chris' pendulous cock slaps back and forth on your hairy muscular thighs. You walk back into your brothers (your?) room and shut the door. You look at yourself in the mirror and can't believe how you look now! You casually flex a bicep and it jumps up, flashing your dark pit bushes. You didn't mind the hair at all, and after the shower you didn't stink much anymore.
Actually, you feel your fat cock slowly becoming engorged with blood, fattening up and getting hard as stone. You close your eyes and will it to go down, which is does somewhat. Ha! Your a dude now, and guys being horny all the time just comes with this new body!
In your brothers room, you pick up the towel and begin to dry yourself off. It takes noticeably more time to dry off, as the water is sticking to all your new body hair. Specifically, your pit bushes, chest hair, and pubes took a lot longer to dry off. Once you were fully dry, you open your brothers drawers and began to look for clothes that fit this new body.
"Uggh", you say as you see only one undergarment in his top drawer that was clean; a yellow, stained, well used jockstrap. You pick it up and give it an experimental sniff. "Oh jeez", you say as the thick smelly musk hits your nose. It stunk really bad. You look down at your crotch and realize that you now make the same man scents. you shrug; it's your smell now, and you know that your brother was a stinky guy. Might as well get used to being a bit more fragrant from now on.
You squeeze into the jockstrap, your now fat cock and balls straining the fabric. The fabric was stretched out from the bulge, and curly thick pubes stuck out. It looked like the band was just about going to snap.
Staring at your fat cock, and hairy muscular body in the mirror, you smile. You are fucking huge and hot! Who cares if your a bit of a stinky fireball, you look great! The thought makes his cock twitch again in the right fabric pouch.
Just than, he heard a knock at the door. "Yoooo Chris, are you in there?". Shit! It was the voice of Carter, Chris' best friend from the football team. What was he going to do?!? Answer the door or hide?!
