Jeff was losing control of himself. A few seconds ago he was sucking on Simon's jockish rod. To make matters worse, Jeff was sporting thick hairy pits, heavy jock balls, and a musky odor that would scare away any normal human being. The musky odor given off by Simon and now Jeff was making Jeff horny and unable to focus. Jeff was so dazed and confused by what was happening, that he didn't notice Simon behind him.
"Look at that smooth ass - just like a baby's!" Simon jeered. "Let's fix that; I real jock needs a hairy ass!" Simon reached down to cup his own tube steak, which was dripping with saliva and precum before he saw Jeff's slightly larger cock hanging with his new jock balls.
"You know what, you got jock balls now so I don't need to help change you. I just gotta coax the jock out of your balls bro!" Simon laughed as he began to stroke Jeff's dick. Immediately Jeff's dick became harder than its ever been and started to leak jockish musky precum.
Jeff was embarrassed to be aroused by the stimulation, but his worries were drowned out by the jockish testosterone flowing into his body from his balls. Jeff felt a wet feeling on his ass as Simon began to rub Jeff's own precum onto his ass, causing stiff dark hairs to cover his ass. The hairs grew wiry and thick as they spread out from the crack. After a few seconds of this musky smearing, Jeff now had a hairy ass that looked just like any other jock's.
Jeff moaned in pleasure. He was desperately trying to fight Simon, but he was slowly losing himself even more to the jockish influence.
