Chris had never felt anything like this before. It felt like he was becoming weaker. It was extremely painful. He felt his bones and muscles begin to contract in on themselves.
Chris was originally 25 years old, only half the age of what Charles used to be. Although now, he felt his muscles become smaller, as more pain shot through his body.
"Uhhhhhhhghhh!" Chris screamed.
Chris realized the same thing must be happening to him that happened to Charles. The only difference was the pain. He didn't recall Charles being in this much pain. Actually, he didn't recall Charles being in any pain at all.
Chris noticed that he had lost a lot of his muscular body. He had went down from being 25 years old, to 20 now. The only difference in his body in those 5 years was the muscle. He had started working out heavily when he was 20.
Chris felt what was like a sharp pinch all over his body wherever there was hair. The small amount of stubble that he had on his face today started retracting into his body. The same happened to every other hair on his body. Except the ones on his head. There were only thin wisps of hair on his legs, his arm pits, stomach, and chest. He felt it in his pubic area as well. He pulled the towel out a bit and was horrified to see that his pubic hair had become thin wisps as well!
He was down to 18 years old now. He was still the same height of 5'10", but that was about to change. He had stopped growing at the age of 18, but he also had a number of significant growth spurts until he turned 18. The once muscular, tall and slightly hairy man was now a young man the same height, with only thin wisps of hair, and a scrawny toothpick build. He had to hold his towel on him, otherwise it would slip off to the floor.
"Unnngggghhhh!" Chris screamed again.
He began to feel himself become shorter, and felt his bones become shorter. He felt unimaginable pain throughout his body as this happened. He felt that pinching feeling again as the rest of his hair retreated into his body, leaving him smooth now. He went down again. He was now 17, and 16 was approaching fast. He continued to shrink down from 5'10" to 5'6".
Chris was screaming again, but he noticed that it wasn't his voice he knew so well. It sounded higher; like it used to when he was 15! He stopped shrinking finally at 5'2". He felt more pain; this time it was from his mouth! He remembered why now; 15 was the age that he still had his braces at! They reformed on his teeth, tightening his mouth like the first time he had them on.
Finally it seemed like the changes were complete. Chris examined himself as best he could without a mirror. The first thing he needed to check, was his crotch. He was almost afraid to look down. As he did, he knew he was right. His penis had gone down a couple inches. He felt so humiliated. He was now a scrawny, 15 year old boy. He was completely smooth of any facial hair, and arm pit hair. Though his groin and legs had a few small wisps of hair on them. He stood a short 5'2", and had braces again.
Charles' jaw dropped in awe as he stared at the now teen boy. He also wondered why it looked like Chris was in so much pain. Could it have been the fact that when Charles fucked him, he was getting all the pleasure while Chris was in pain? Charles didn't think he hurt Chris. He never meant to or wanted to.
Charles was strangely turned on by the younger Chris now. He knew he'd have power over him now. So he could make him do whatever he wanted. That wasn't right though, and he'd feel terrible if he took advantage of this kid.
Chris...
