"Ugggh", Jeff moaned in his new deep voice, his adam's apple bobbing up and down. "Simon, please stop!", Jeff begged, as his hands explored his ass. He now had an incredibly thick covering of hair all over his ass. "This is disgusting, who wants ass hair!?". Simon, standing over Jeff, was chuckling. His hairy chest was proudly pumped out and his big jock bulge was poking out of his jockstrap. "Don't be such a bitch, Jeff. You will love this soon enough!". Jeff staggered to his feet, his large balls swaying in their sack. Simon kept talking down to Jeff; "See, look at your big hairy jock balls! Your going to turn into a jock Jeff, its only a matter of time!".
Jeff glanced down at his balls. Jeez, they were big; bigger than jumbo eggs. Plus, they hung pretty low. And they were absolutely covered in hair; it disgusted Jeff. While Jeff was distracted staring at himself, Simon reached over and grabbed his balls. Simon squeezed his balls quite hard. Jeff arched backwards and gave a deep throated bellow in his new voice. Simon smirked as he squeezed even more.
That was all Jeff's balls needed to start working. Almost immediately after Simon squeezed them, Jeff's small penis instantly became hard. It was throbbing hard, and gaining length and girth with each pump. Jeff also gained a bit more peach fuzz on his face and he sprouted more hair on his body. His very light and sparse pubes grew out a bit more and became a bit darker. The hair on his upper lip darkened and thickened a bit as well; it was still very boyish, however. It looked like he smeared a bit of dirt on his lip.
Jeff stumbled back from Simon and cradled his new hairy jock sack. Simon was no longer touching his sack, but the changes continued. Jeff looked down and saw a few dark, but rather thick hairs squirm out around his nipples. Other than the few dark nipple hairs, that was all the chest hair Jeff had, at least for now. His penis finally stopped growing at around 6 inches; something told Jeff that was nowhere near it's final length.
Lastly, Jeff felt a tickling under his arms. Jeff raised his right arm and started scratching his heavy pit bush with his left hand. As his fingers raked through the thick smelly jungle, he realized there was more hair. He stopped scratching and stared at his hairy armpit. He could see the hair growing thicker and longer by the second. And, if his nose was correct, he stunk even worse. He was hairier and had worse body odor!
Jeff was dismayed. His body was betraying him. his balls kept producing testosterone and he couldn't stop it. He was just going to get hairier and smellier until he was totally a jock!
Simon was watching Jeff observe his growing armpit hair. He chuckled to himself in his new manly voice; he knew what was in store for Jeff...
