Walking down the hall, Janine wished there wasn't going to be a game tonight. Even though she just had sex with Todd, her sex drive was still in full gear. Then she remembered the bag with all her cheerleader gear was still in her locker, so she turned around and walked back the way she had come.
She pulled the bag out of her locker, and then heard a noise behind her. She slammed the door shut and turned around to see Marvin, one of the geeks in Mr. Campbell's math class. He was pale, skinny, and short, only 5'. He wore a button down shirt with khaki pants and glasses. His greasy brown hair was parted in the middle, and the only hair the 14 year old had on his body.
"I saw what Rhianna did to you in class and looked everywhere for..." Marvin began before the pheromones took over. Janine, who still had an itch to scratch, saw an opportunity. She grabbed him by his shirt and pulled him into the guy's bathroom.
She quickly undressed and then helped Marvin rip his shirt and pants off and then pushed him into a stall. While he stood, Janine went down and gave him the first blow job he ever had. His cock slowly hardened from 3 inches to its max, just shy of 5. He was too enveloped to notice that it then kept going, growing from 5, to 6, then 7 inches all while Janine worked her tongue.
Unable to go any longer, she then raised herself up and Marvin thrust his now larger cock inside her pussy. It was warmer than he expected and a tingle went over his body. His body then began to grow. He gained a foot and a half in height while his muscles swelled. He developed a six pack, large calves, and guns that an arm wrestler would envy. His vision became clearer, and as he gained strength, he pounded furiously into Janine, who then began to orgasm. Marvin's hair shortened into a sloppy style and a 5 o'clock shadow grew out on this face. Pubic hair sprouted up along with some chest hair and a treasure trail. His chin became more rounded and his shoulders looked wider. That's when he came, spilling seed into her with his fully grown 10 inch cock.
He fell back and sat on the toilet while Janine collapsed, wide awake, on the floor. He no longer had memories of the intelligent freshman he once had been. He was now the biggest guy on the wrestling team. The transformation had been so much that he then passed out.
Janine stood up, looked at the man she just fucked and smiled. He had been good. She stepped out of the stall and threw his clothing, including a letterman jacket, into the stall and closed the door as best she could. She was picking up her clothes when the door opened.
