"You have finally awakened, Mark."
" Hmmf, what happened? Where am I?" Mark said as his dizziness dissipated. "Who are you?"
"My name is Adams, I was assigned to take care of you while you adapt." Adams told him. "I bet you're hungry. I'm going to prepare you something to eat."
Adams left the room, leaving Mark alone.
"My body hurts everywhere." Mark groaned as he tried to stand up. He felt so rigid like if he was sleeping for a long time. He looked around trying to recognize something familiar but he was on a cottage that he had never been before. It looked simple with just a few things, including a large mirror on a wall.
"Woaah!!" Adams heard followed by falling sound. He thought that something had happened to Mark and he ran to his aid. Mark was on the ground with a shocked expression on his face.
"What happened? That's me?" Mark wondered. "I-I'm huge! I'm big and old and hairy!"
Adams noted that Mark was panicking and he realized that Mark didn't remember what happened to him in the laboratory. He helped him to stand up and then he invited him to go to the kitchen with him. Mark realized that although Adams looked like a twenty something years old guy, he was taller than him.
"Do you remember something?" Adams asked as he returned to the frying pan.
"Nothing." Mark said. "I remember I was in my friend's house, then I was in some odd facilities and now I'm here."
"That's something." Adams said. "I can't tell you all the details but I can say you were chosen for a new secret experiment sponsored by an important pharmaceutical consortium. Our objective was to study male hormonal development and we managed to understand it in order to manipulate it."
"Male hormonal development?" Mark questioned. "You mean testosterone, right?"
"That's right. We can alter testosterone level artificially on humans." Adams said as he finished his cooking. "However, we can only do it on those whose hormonal levels are still inactive."
"What does that mean?"
"Prepubescent boys like you." Adams said as he put a plate with eggs and bacon in front of Mark. "We called it pubertification because we produce a similar but accelerated effect on your bodies."
"That's why I looked older." Mark said he could be furious right now, but he seemed calmed instead. "How can I change back?"
"You can't..." Adams said as he put another plate on the table. "Pubertification is one way only. I'm sorry."
They stood quiet for a moment and then they began to eat their meals. Occasionally, Adams glanced at Mark but he can't realize how he feels about what he told him. When Mark finished his food, he spoke again.
"And... Why I'm so big and older?" Mark asked. "I mean, I know I'm older now..."
"Biologically 26 years old." Adams briefly interrupted.
"26?! That's more than twice my former age!!" Mark astounded. "Anyway, what I'm trying to say is that my family isn't about tall nor hairy guys. I'm totally different from my dad and uncles."
"As we can manipulate your testosterone influence through your body during pubertification we can make you grow differently from your genetic code." Adams said and blushed a little. "My boss has a little... ehem... predilection for jocks, so all our test subjects got jock like bodies because of that."
"So, I'm not just older but a jock too?" Mark seemed a little pissed now. "Great." He suddenly left the kitchen and looked at himself in the mirror again. "And now what? What am I supposed to do? Play football or something?"
"If you want it, but not necessarily." Adams said as he approached him. "You can do anything you want that could help you to get used to your body. Running or playing a sport is a good way to start."
"What about other stuff like clothing and hygiene?" Mark asked as he stared at his exposed hairy chest.
"I packed some clothing for you, a toothbrush and a deodorant." Adams said as he put a bag over Mark's bed. "I also packed other stuff that you could need, a shaving razor, foot deodorant and... condoms."
"Condoms?!!" Mark wondered. "Do you mean that-?"
"See for yourself." Adams said as he unpacked Mark's stuff. Mark put down his loose pants and immediately realized that he wasn't wearing underwear. An impressive hairy bush of pubes jumped to his sight and he felt awkward of it but it wasn't nothing compared to when he saw his dick for the first time.
"Oh my god! It's huge!!" Mark shouted and Adams just smiled. "Why it's so big?"
"It's the right size for a jock, remember?" Adams replied. "According to my investigation, you'll be horny frequently until you get used to your body." Mark blushed. "So, when you feel the need to... you know... touch yourself, well, feel free to do it anywhere as long as you're inside the house." Adams finished unpacking and walking to the front door. "I can see you could start right now, so I'll give you a little privacy while I'm going to the market."
Adams left the cottage leaving Mark alone with a growing boner.
"I don't know..." Mark muttered to himself. "It's not right... I mean, I'm still 12 in mind..." Although he was doubting, his hand had started stroking his pole and glossy precum was dripping from his swollen dickhead. "It feels so bad and good at the same time..." He softly moaned as he was sliding down a wall and sat on the ground. "Oh, god!" It was the first time he did that but he felt that it's like he had done it for years. He wasn't just stroking his dick now, but he was using his other hand to massage his new testicles. He can't describe it but he felt like intoxicated with pleasure. In no time, he was jacking off like a pro.
"By the way, there's another guy coming here at the noon!" Adams suddenly opened the door and astonished Mark who immediately left his dick a second before he got his climax. He really looked pissed off now. "Oh, I'm so sorry! I didn't mind you'll be doing it so quickly. Sorry!"
Adams left once again and Mark sighed before he tried to keep doing it. However, his dick getting soft. "All right... Let's start over."
