A new boyfriend for Lindsey: Karyn, err.. Kevin.

Suddenly Karyn felt very strange, and her hair receeded into her scalp. At the same time she saw her breats deflating into a very manly chest, complete with pecs and curly hair. "Oh my.. she said, but her voice lowered, gaining a deep tone. She gained muscular mass everywhere, and her legs and arms grew some hairiness too. Her face hardened, her eyebrows becoming thicker and she grew a short stubbly beard. A ingrowing penis grew from her former vagina, complete with scrotum and balls.
"Well, hello, Kevin!" said Lindsey, grinning at her boyfriend.
"Kevin!? My name is Kar.. is K.. is Kevin, you're right, honey!"
Said the former Karyn while new memories flowed into her head.
