Dave stared at his naked body in the mirror and shuddered. He was so much taller and bigger now! Thick and developed muscles were bulging all over his body, and thick brown body hair was sprouting everywhere. He saw the huge rug on his muscular chest and the 2 jungle like bushes popping out from his pits. So gross! he lifted up his long, powerful arm, and took a sniff of his armpits. "Oh god, I smell so bad", he muttered to himself, still shocked by the deepness of his voice.
Dave's eyes trailed down to his abdomen, where he had a 6 pack, which was barely visible through all the thick wiry hairs. He saw his huge bush above his cock, and then he laid eyes on his cock again. It was so unbelievably big! It hung soft at about 9 inches, and it was very thick. The weight of it hanging from his groin was unreal, and every time he moved even the slightest, he could feel it's weight swinging around, banging against his legs and his thighs. Likewise, Dave could see his huge, hair covered balls swaying behind the huge cock. Dave scrunched up his face in disgust when he saw he was leaking precum everywhere! There was a small sticky puddle on the carpet already. "Gross!".
Dave could see his body was glistening with sweat, and his body odor was so bad it was easy to imagine cartoon stink lines and flies swarming around him. He didn't have much time to figure this out before someone came home, but he decided a shower was absolutely necessary. He walked into his bathroom and shut the door.
Stepping under the water, he felt all his body hair getting matted down by the spray. It felt so weird being so hairy now! He must be one of the most hairy guys in school now! He grabbed a bar of soap and lifted up one of his massive arms. He rubbed the bar of soap through the huge bushes he now had, getting rid of his pit stink. Part of his liked his new BO, and that scared Dave. He lifted up his other arm and scrubbed that one clean as well.
10 minutes later, Dave stepped out of the shower. It had taken him longer than he thought it would, as his body took longer to clean with all that hair! Plus, Dave needed to wash both his pits and his hairy pubic bush twice, because the smell was so strong. Washing his huge cock had made it go rock hard, much to Dave's annoyance. He ignored the potent hormones and the overwhelming urge to jack off, which was very difficult not to do. He turned the water to cold and his cock slowly died down. Dave was annoyed; he figured he would always be horny, all day, every day, no matter what he did from now on.
Drying himself off with a towel, Dave began to think about what course of action he should take. He wanted his old, nerdy, prepubescent body back! His old body didn't stink or have hairs busting out all over himself. His old body certainly didn't have to deal with annoying erections or precum stained pants!
While he was thinking to himself, Dave heard to front door downstairs open. Dave snapped out of it; "Oh no, someone's here!", Dave said.
