Ty raced back to her house and soon she was back in her room. Locking the door, she pulled off her dress and underwear and looked at her body in her closet mirror. It felt strange to see a girl's body in her reflection after all the years where he'd seen a boy's body in his reflection, but she felt pretty like this. Something about being female just felt right.
The really surprising thing was she didn't feel that turned on by seeing a naked girl. Her mind was much more interested in guys' bodies, especially her memory of Eileen. Just thinking about that handsome man who'd fucked her earlier that day was turning her on, especially when she remembered his cum was still leaking from her ass and pussy. She curiously moved her hand down there to wipe some of it off, and couldn't resist the urge to suck her fingers clean, tasting his strong salty tang.
The taste evoked vivid, arousing memories- his body reshaping from female to male, his firm muscles holding Ty down under him while he fucked the boy's ass, Ty seeing her body turn from male to female, having Eileen pound her and fill her with cum, and sucking the juices off his hard shaft...
It dawned on Ty all of a sudden what it meant that Eileen had filled her with cum. She had a strange vision, seeing in her womb an egg eagerly awaiting fertilization- and seeing Eileen's seed surrounding it, wearing away at its walls until one reached the inside, fertilizing it and helping it to implant inside Ty.
Ty's eyes widened as she realized what her vision was telling her. "I'm pregnant," she breathed. Something she hadn't considered much about her new sex was now asserting itself- a sense of castration and emasculation. He had relinquished his manhood, and she had allowed a man to mate her. In her mind's eye she saw her stomach grow large and round with their child, and felt a weird satisfaction about it.
She wondered whether to follow her body's reproductive instincts or not...
