"I wish you were a guy"
Suddenly tiff falls over onto the floor. The sensations all focusing on her pussy, which is now raging hot and wet. She can feel it under her skirt, moving her hands down her shirt and under the waistband of her skirt and panties she shoves her fingers in with no abandon.
"Oh whoa! Tiff!" Tiff was masturbating furiously with no thought of katie's presence. All she could focus on was the heat in her pussy. Her fingers moving fast on her clit she couldn't stop it no matter what she did. Then she felt something hard coming out, she couldn't explain it. It was warm and then she could feel it as if it was a part of her. She could feel her own pussy walls constricting around it, then it was like she was having two orgasms at once. One from her pussy and one from this new thing. Ripping off her skirt and panties she splays her legs for katie to see. She doesn't know why, but she needed katie to watch it was for her this was happening. Katie did watch too, as the plump throbbing cock head poked out and then pushed the shaft through. It must have been nine inches at the least long and thick. Two big hairy balls plopped out behind it. The pussy it came out of seemed to melt away around it.
Katie noticed also how the tiff's big boobs began to melt away and she became more and more flat chested. Muscles began to develop on her arms and legs and her face began to become rougher and fill out and become more masculine. Long hair became short and in moments tiff was gone and a ruddy good looking guy was in her place. He was panting as if he had just experiencing the greatest sex in his life. His hand going to his new cock and beginning to masturbate again not stopping until he cums on the floor. Then stopping he takes a moment and then with a growl gives katie a smoldering look.
"I thought you said you wouldn't do anything drastic you bitch."
