Casey stood outside the bathroom turned milking room, looking for her final victim. She wanted a goth family for the fourth story of the house, and a girl named Gwen caught her eye. "Hi there!" Casey said to her, as Gwen was immediately infected with her pheromones. "Hi" Gwen said, feeling shy and attracted to Casey. "Can you help me with something? What's your name?" she asked Gwen, and Gwen answered and followed Casey to the milking station. Gwen was about to ask what Casey need help when she was suddenly kissed by her. Gwen happily accepted the kiss and started touching Casey, taking off her skirt as they undressed each other. Gwen stopped and pulled her panties off, wet from making out. Casey couldn't wait and immediately stuck her massive penis into Gwen. Gwen came several times, happily letting Casey fuck her, until Casey finally came in Gwen. Gwen immediately felt odd, but not in a bad way. Casey also started feeling odd. Gwen's memories and body changed. Her height went from 5'0 to 5'6, and her breasts became milk filled h cups. Her ass expanded, and became even larger than her chest. A massive 18 inch penis, with softball sized testicles, grew above her hairless pussy. Her waist thinned, giving her a perfect hour glass look. Her skin became permanently pale, even more so than Casey, and a choker appeared on her neck. Black lipstick became permanent on her lips, as did her other makeup. Her memories changed to make this all normal as her clothes changed into a goth dress and high heeled boots with thigh high socks. However, Casey started feeling odd as well. She stared at Gwen's New body, seeing as he favorite Futa... Gwen felt the same. Casey gave Gwen a spank, and old her to come into her room once her family was finished changing. Casey went home, satisfied for the day. She went up to her room and fell asleep, having wet dreams about Gwen.
