Once Tyra reached the gestation wing, she saw on a screen in front of her an egg surrounded by sperm desperately trying to break inside it. She knew instinctively this was what was occurring inside her, and as one sperm burst inside and fertilized the egg, she realized she was pregnant with the child of the boy who had just fucked her.
The powers of the wing made the pregnancy far quicker and more comfortable than normal. Tyra's stomach soon swelled up with the fetus inside her, rapidly giving her a pregnant belly, but she felt no pain or discomfort even as it grew large and her breasts began to lactate.
Soon she felt the contractions in her vaginal muscles that marked the start of childbirth, but to her relief the pain of labor was almost completely absent as she slowly bore the child that had been conceived inside her. The machines of the wing cut her child's umbilical cord, and she took it in her arms and cradled it before allowing it to suckle at her breasts.
Tyra didn't even get to catch whether her child was a boy or a girl before the wing took the child to mature and sent her on her way. She felt a mix of excitement and trepidation at knowing she'd be made male again now.
She began changing before she knew it. Her vaginal lips sealed shut, and she felt her ovaries slip downwards and reshape until they plopped into her sac as testicles, rapidly generating countless sperm. Her breasts shrank away until she had a flat, unsensitive chest, and her body bulked up a little into more masculine proportions. Her clitoris widened and lengthened, its hood turning into a phallus as the nub itself became the tip of his penis.
Now a boy again, Ty eagerly awaited getting to knock up another girl...
