Before she could focus on making another wish, Ty felt something unfamiliar inside herself. It was an odd warmth, just as strong and hormonal as she'd experienced as a boy, but totally different, emphasized by the sensation of her lover's cum inside her. She felt his virile seed pervading her insides, reaching her womb.
And suddenly she was aware of something inside it. Where once she had had masses of seminal fluid and sperm in her, now her reproductive organs had transformed there was just a single reproductive cell, an ovum formed because of the surge of feminine hormones through her changing body. An ovum that lay in wait for fertilizing.
The seed from her lover rushed to it, and all of them tried to wean their way inside. Soon enough, one made it through, and the feeling from the ovum reverberated through her as it instinctively settled in the wall of her womb and started to multiply and grow into many cells.
Ty knew, of course, this was the effect of her wish, and women didn't usually 'feel' fertilization. But it had felt so good, she didn't mind not having a 'normal' experience of being impregnated. Her eyes had glazed over, visualizing this process inside her, and what she saw when they focused again only emphasized it in her mind. She looked at her lover, and admired the cute face their children would inherit, the handsome body that had just fucked her, the thick cock which had filled her with cum and fertilized her.
"Are you OK, babe?" he asked softly.
She nodded, leaned forward and kissed him.
