"Jen, are you alright?" her mom asked.
"Ye, Yeah." Jen answered.
Her mom opened the door "Oh dear, is it that time of the month again, you always get so aroused."
"Yeah." Jen answered not knowing what to say.
"Well, you just stay home from school and take care of yourself, you don't need to swing that staff of yours around anyone today."
"Okay."
"Well, I'll be off to work, just please don't masturbate in the living room again, it's so hard to get semen out of the carpet."
"Okay."
Jen's mom left, as she turned around and walked, Jen's member jumped to attention, she had looked at her mom's ass not being able to control her gaze. Jen stood up, she noticed that she was taller, she waited until her mom had shut the door until she rushed to her full body mirror, her footsteps thundering along the way, she looked in the mirror and cried. Her body was now more than three times it's original size, her shapely figure gone, filled in by a mass of brawn, still noticeably female, but with her massive cock she couldn't tell herself that. She didn't know what to do, crying and not paying attention, she started stroking herself, she tried to stop but she just kept going, she instinctively reached for a bucket that had appeared by her bed, now on a steel frame which still creaked when she sat on it. She just watched as her body took care of itself, she cam into the bucket, but was still hard.
"What am I going to do? I can't let anyone see me like this!"
Then there was a knock at the front door, she went to the bathroom and grabbed a towel, wrapping it around herself, trying to hide her massive boner, and went down to answer it.
