Staring at your brothers body, that you now inhabit, in the mirror was such a trip. You can't believe this was now you! With all these muscles and hair! Looking at the thatch of brown hair under your arms and the heavy odor wafting off your body told you it was time to take your first shower in Chris' body. Hopefully it will help with your new BO problem, but you aren't hopeful; you can personally attest that your brother is one smelly dude.
Looking down at your thick hose of a cock, you could see it looked like it was sweaty and your new thick pubes didn't look the cleanest either. You cup your fat hairy balls and sniff your hand. Oh gross! Yeah a shower was definitely in order!
You walk to Chris' bathroom, still not used to your bulky new body or the cock slapping between your legs. Stepping into the shower you turn on the warm water. It feels really good on your thick, hard muscles. You hadn't realized they were sore before, especially your shelf like hairy pecs. Chris must have just had chest day before you got this body. You touch the hairy muscles and chuckle. It feels awesome.
You have a quick shower, wanting to get back to his room and explore this new body. You quickly take the bar of soap stuck with a bunch of his (now your) curly body hairs (yuck!) And scrub yourself. You pay close attention to your hairy armpits, butt, and chest. Jeez, it's like your whole body is covered in fur! It takes noticeably longer to clean your new body now. You soap up your pubic hair and start to soap up your cock. You gasp at the touch of your slick hands gripping your new cock. It was so sensitive, and so big. You quickly wash off and try to think of something else, before you pop a huge boner in the shower.
Stepping out of the shower, you grab a nearby towel and begin to dry your body.
