Unable to think about anything but him, Jennifer continued to try and mount her twin brother. As she did more changes began to take place. Her breasts sunk into her chest turning into muscular pecks instead. Six pack abs formed on her stomach and her hands and arms became masculine and well toned. Her hair began to shorten and turn black. All the while her brother looked on in shock. What was happening to her and more over why was she obsessed with him. Her ass firmed up and her legs grew long and muscular. Hair began to cover her body every where except her chest, which was smooth and shiny. The last remaining facial features that told she was once a girl disappeared, a chiseled chin and dimples took form as did a five o'clock shadow. Her eyes turned the brightest blue and lastly her skin turned a golden shade of brown. Her brother pushed her back onto the bed. Minutes ago this person laying there was his sister but now she had become the boy of his dreams, a young Latin jock he had always wanted to fall in love with. Quickly memories of his sister began to fade from his mind as he jumped on top of his new boyfriend.
