Embarrassed by Vivian's word, Ryan ran away from the room. His pendulous dick was moving side to side with each step he made.
"I could be naked full time but that doesn't mean that she should see me." Ryan said as he walked to a empty room. He closed the door and he his broad back on a wall and slid down. "I don't know what to do." He sighed as he stared at the mounds in his chest that partially hide his dick from his sight. "This body is super awesome but I don't wanna be Vivian's fucktoy..."
Meanwhile, Bradley had entered the shower, he wasn't too used to his new height that he hit his head a few times. "Ouch!" He said as he rubbed his forehead. "It hurts, but it worth it." He took the soap bar and started to move it across his body. It was his first time showering like an adult, so he felt a strong bliss of joy as he touched every muscle and hair that he has now. He spent extra time soaping his armpits, his butt cheeks and, of course, his cock. He can't help but moan all the time. As he rubbed his dick he slowly started to massage it, and then it leads to a vigorous jacking off that ended with a strong shot of cum on his bigger chest.
The kitchen phone was ringing and without Ryan or Bradley on sight, Vivian had to take it. "Hello?" She said.
"Hi, miss Vivian. I'm doctor Collins." The voice said. "I wanted to congratulate you for your excellent work with those kids."
"It was kinda easy." Vivian smiled. "And I'm getting a good sight as well, I could call it a win win deal."
"Excellent." The doctor replied. "However, we're on the third day of our experiment and we need to proceed with the next tests."
"And what are those tests about?" Vivian asked. "Is something even stronger than the male enhancer drug that you put on them?"
"Perhaps." Doctor Collins replied. "Maybe you don't know it, but the male enhancer is a very strong drug. Those poor kids won't go back to childhood after this second growth."
"Really? That's evil!" Vivian laughed. "So, tell me about the next tests."
"One of them is going to be in the air." The doctor said. "But don't worry, it only affects chromosome Y. It increases sperm production to insane levels! Our intention is to use this technology to cure the male infertility. It has a lot of funds from old rich men who want to keep having descendants."
"That's sick." Vivian said. "Those kids are going to end up like human cows! Hahaha!"
"That's where we need your help." The doctor proceeded. "In order to watch their semen production, we need you to order them to jack off continously. I know that you have a deal with them. A very clever one in my opinion! So, it won't be a problem for you."
"And what will happen if they don't jack off?"
"Well, it will definitely happen. When they sleep, for example." The doctor replied. "The semen won't stop increasing and like water balloons their testicles are going to swell. We have the theory that the balls growth will be permanent, so unless they want beach balls between their legs they should cooperate."
"Ok, that would be hilarious!" Vivian laughed.
"We count on you, miss Vivian." Those were the doctor last words.
"Who were you talking too, Viv?" Bradley asked her as he came out from the shower with a towel on his shoulders.
"A friend." She said as she stared at Bradley's balls. They don't look bigger, so she assumed that he had jacked off in the shower. She grinned and invited to watch TV in the living room.
