Ty looked up at Eileen and smiled. "You know, since you knocked me up with another baby, I have a crazy idea for how we can use my power."
"What's that?" Eileen asked.
"You'll see," Ty replied mischievously.
She made her wish, and her and Eileen's perspectives shifted. They were inside Ty's womb, inhabiting the xygotes that had formed inside her. "Wait... did you just wish for...?" Eileen asked, communicating in Ty's head in ways the two of them could barely comprehend.
"Yep," Ty answered. "Next, I'm gonna do this..."
The view they had changed once more, though they were still in their xygote bodies. They watched as Ty's belly swelled while they grew inside her, until at last her water broke and she gave birth. The newborns that emerged were a boy and girl, both with skin a beautiful mix of Ty's fairness and Eileen's darkness.
Next Ty wished their old selves away, and for them to age. Within seconds, both Ty and Eileen's new bodies had developed from infancy to adulthood.
"Oh hey, I'm a woman again!" Eileen noted as she looked down at herself. She had the body of a fit 18-year-old girl, and it felt strange to have large full breasts and a vagina again after the long break.
"Yeah, and I'm a man now," Ty smirked as he looked at his fully developed body. He had more toned muscle and felt more strong than he ever had- though it might just have been having a penis and belonging to the male gender once again that made him feel like that.
The two of them felt aroused as they saw their partner's attractive naked forms, and Ty felt himself grow hard while Eileen noticed she was getting moist between her legs. Ty kissed her and pushed her down, and she giggled. "So are we gonna have sex again in new bodies? Is that your crazy idea?" she asked.
"It’s a bit crazier, actually," Ty admitted. He wished for Eileen to be ovulating, and inside her ovaries two eggs formed, fresh and ready to be fertilised. He made sure she felt it, and she blushed. "I was thinking we could recreate ourselves over and over," he explained. "I fertilise two eggs inside you, which we use to be birthed as new selves. Each time we swap genders and fuck again. We can keep doing it as long as we want- even forever." He paused and blushed. "Like I said, it's kinda crazy."
