...intensely turned on by the memories and how her body felt. The contrast with his old self, and how intense the instincts of her new self were, was intoxicating- any conscious queries about how his body was changing into her body were overshadowed by how much she liked becoming female.
She moved her fingers from her pussy up in front of her face, seeing Eileen's gooey semen covering them. Not long ago he had produced it en masse himself, but to her it was scarce and unfamiliar. She put her fingers in her mouth and sucked them clean, the strong salty tang of her lover's cum making her head swirl. She pictured the thick, dark penis that had filled her with this seed- and his own penis, receding in subservience to her lover's as he became castrated and feminised, and her body prepared for him to mate it.
Her hand traced back to the hooded nub at her crotch, the form now taken by his penis. She gasped as she carefully stroked it, her clit way more sensitive than his dick had been. Ty had no regrets about giving up his phallus or the ability to fertilise- having this sensitive nub and being able to get pregnant felt so much nicer. Her fingers dipped into her juice-covered slit, the vagina that had formed from his scrotum, and she felt her pleasure heighten further as her lover's semen seeped from her.
A warmth in her chest was by now impossible to ignore, and she reached with her free hand to play with her soft mammaries. It felt weird to think this had been flat and pretty unsensitive, what with how they had grown large and soft and having them cupped gave her intense pleasure. It emphasized how much she'd changed, too, as she knew one day her and Eileen's child would suckle at her breasts and she would nurture it.
Ty continued to grasp at her chest, rub her sensitive nub and finger herself as she edged herself towards greater and greater heights of pleasure. In her head the vision of her transformation was repeating, re-emphasizing how she had become a woman, as was Eileen mating with her, reasserting to her that she was pregnant with his child. It felt weirdly like fantasies Ty had had about fucking girls he liked and knocking them up, except she had taken on the feminine role herself. She felt like one child of Eileen's wouldn't be enough- she ached for him to fuck her over and over, making him bear uncountable offspring of his, to get used as a breeding fucktoy. His masculinity incomparable to Eileen's, so she would embrace femininity so he could breed her...
And her mind made her orgasm hard. She moaned sultrily and clenched around her fingers, her nipples and clit pulsing against her touch. This orgasm had been the most intense she'd ever had outside of having sex with Eileen, and it took her a little while to recover compared to when he'd been a guy. She slowly stared at herself gasping in the mirror as she came down from the high, ideas swirling through her head...
