Ty knew which desire she wished to satisfy most. She was finding herself disagreeing with Eileen more and more- not only did she feel like yes, she could deal with getting pregnant with her powers, but she wanted to get pregnant too. A lot. She wanted a guy to fuck her up and fill her with his seed.
In a haze of arousal and desire, she wished her dream guy into existence. A second later, he emerged into existence, a handsome blonde teen with a toned, slim figure and a large erection between his legs. He climbed onto the bed, positioned himself atop Ty and she kissed him. Even though she'd just cum, she felt more aroused right now than she ever had in her life as she felt him kiss back and press his tantalisingly hard body against her soft, yielding one. Once their kiss broke, his lips slid down her neck and reached one of her breasts, carefully sucking at the nipple and making her moan softly.
He moved back up above her and positioned himself so that the tip of his cock kissed her clit, and she shivered with anticipation. He spoke sultrily, and since his existence was predicated on her consent, he made no effort to ask her permission for anything. "I'm going to mate you," he purred. "I'm gonna hold you down and fuck you until I fill you with my seed."
With that, his head slid down to her moist vaginal lips and he slid inside. Ty gasped, and unlike Eileen, this man refused to give her any time to adjust. His hips pistoned in and out of her, his cock filled her and withdrew from her, his balls slapped at her forcibly. The only compromise he made to her pleasure was grasping at her breasts now and again, the rest of the time holding her hands down as he fucked her, but the way his cock felt as it thrust in and out of her at an absurd pace was just so tantalizing it didn't matter.
Soon both their orgasms drew near, and deep groans of satisfaction fell from Ty's lover's mouth. "Fuck... I'm gonna..." he breathed between thrusts, his hips seeming to thrust more erratically and eagerly and his hands gripping Ty's chest tighter. At last he came, thick warm seed shooting deep inside Ty's pussy, and the sensation of his cock twitching as he began to ejaculate made Ty cum too. Her inner walls pulsed around him, clenching as tight as she could to keep as much of his warm semen inside her. She moaned shamelessly as she felt highs of arousal even greater than her last orgasm. This is what it was to be a female and get bred by a male, and she loved it.
And while they came, her lover's seed set about fulfilling their biological purpose. Innumerable sperm surrounded a fertile, waiting ovum inside her, all working to wear away at its walls until they allowed one inside, fertilizing it and guiding it to settle inside Ty. Soon it managed to impregnate her, and Ty had fully transformed from a young man to a mother-to-be.
