"You could become a girl too, Joe! It feels so good!" Sherri chirped. Sharon's mind remained intact, even though she was trapped inside the vapid shell of the little slut Joe had made her into. Working within the constraints of her altered personality was difficult, but maybe she could get the pervert to make a mistake of his own...
"You know, that might be fun. I wish I was a beautiful girl." Joe's body began to change, as he became smaller in size, his skin becoming smooth, his muscles losing definition. His penis shrank inside as his genitals became a girl's pussy, his hips widened, and breasts began to form on his chest. His hair grew to shoulder length, his nose shrank, and his facial features became delicate. Soon his body was softer all over. His hands and feet were smaller. He was a girl.
"When I'm like this, call me Jo. No e." His voice, now her voice, was soft and feminine. She weight her breasts and smiled. Then she lay down. "Lick me out, Sherri."
Sherri got to work with a smile on her face, and soon, Jo's fingers were in Sherri's hair, pushing the girl closer as her little pink tongue teased her clit. "Oh you like this, don't you Sherri? You love a girl's pussy."
Sherri pushed herself harder- the more Jo talked, the more her mind was changing. She had to get the taller girl to shut up while she plotted her next move! Soon, thankfully, Jo was reduced to whimpering and moaning softly. Unfortunately, Sherri found that she was enjoying this immensely, so even after Jo came, she didn't stop, cleaning her 'mistress' completely.
Jo was lost in a haze of pleasure. How amazing this was! "Oh Sherri, that feels so good. I wish I had two of you."
There was a flash of light, and where there had been one Sherri, now identical twin Sherri's crouched next to one another. They looked at each other in confusion- each was an exact copy of the other.
Jo sat up. "Oops. But you know, this works out. Sherri...and um...hm...Sharra." She pointed; the girl on her right was Sherri, and the one on her left was Sharra. "Why don't you have sex with each other?"
Unable to resist Jo's command, the two girls began making out, eager to please their 'mistress'; but deep within the recesses of their minds, they were disgusted at making love to a child. The both came at the same time, their faces pressed into each other's crotches. As they lay in each other's arms, they wondered how they could escape this fate.
