It was just then that Jen's door opened and she heard her mom gasp.
"Jenny! Look at you! You've had a growth spurt!"
"But mom!" Jenny cried in her new baritone, manly voice "I'm a girl!"
"Now, now young man, that's no way to speak to me. You know it's perfectly normal for a few little girls to be men and a few little boys to be women. Now you just enjoy exploring you new... body." Her mother seemed a little distracted by her, as she shut the door she yelled downstairs. "Honey! Our little girls' a big man now!"
"Wonderful! I always wanted to have a She-man!" Her father replied.
Jenny was stunned, she didn't know what to think until she remembered what the note had said. This was all because of that note, and now she was stuck with this towering hulk of a body. She wobbled over to the door and locked it, she wasn't used to being so tall and big and she didn't want to be disturbed for a while. She walked over to her bed, her new weight apparent in her every move, she had lain herself down as best she could but her back was now against the wall and she still didn't come close to fitting in her little bed.
She stared at the vast and powerful expanse her body had become, noticing every little chiseled part of her body, then her eyes came upon her new cock. It throbbed, mommy had told her what it was for and how little boys play with it, she reached down and started to stroke her new member. It was pleasurable as she got further into it, she reached down and started to fondle her new balls, it felt even better. Then suddenly there was a new warmth as she watched herself cum for the first time. She grunted, she didn't like her new voice, but that felt so good she didn't care.
Staring at herself once more she saw her cock relax, her new body covered in sweat.
"I have to live with this now." She grumbled "I might as well enjoy it."
