"Thanks," Jessie breathed, both of them lying there for a little while while they recovered. Ty felt Jessie's cock slowly softening against her stomach, and remembering what the girl had said about it, wondered if she could use her power to make Jessie more comfortable with her body.
"Hey Jessie, can I ask something?" Ty said shyly.
"Yeah?" the other girl replied.
"Sorry if this sounds gross, but, um... if you could have a pussy instead of a cock, would you want to?"
Jessie laughed. "Duh! I've been saving up for bottom surgery for like 6 months!"
"In that case," Ty smiled, "I wanna do something for you." She focused and wished that Jessie's penis would turn into a vagina, and kissed down her soft chest and stomach slowly, seeing the girl's expression turn from amused to surprised.
"Ty, wha-ahhh~" Jessie heard her voice evaporate into a softer moan than she'd ever heard herself let out, and she and Ty's eyes focused on her crotch as they saw it reshaping. Her phallus was receding and tucking inwards, growing more and more sensitive as it protruded less and less from her body. She felt her testicles move up inside her and link to a forming group of parts which were nothing like what she'd had before. Her scrotum shrank until instead of a sac at her crotch she had a mound, and the seam binding the skin together unsealed allowing lips to form which dripped with clear juices.
The only part of Jessie more enraptured with pleasure from the changes than her body was her mind. She felt herself relinquish any connection to being male, and it was the best feeling she'd ever had. This was how her body should be, and no one could even try and tell her she wasn't a woman!
Once her vagina had finished forming, Ty moved up till she was face to face with Jessie, and asked, "You OK, Jessie?" The girl had an ecstatic expression fixed to her face and could barely focus on anything. Ty figured she was probably happy about the change, and wondered what to do next...
