Ty's question took Eileen by surprise. He remembered very well how it had felt as much strange and scary as exciting to have a child, and she'd been almost a decade older than Ty when she had gotten pregnant. "Are you sure you want to do that?" he asked cautiously. "I know it must seem really hot to you as someone who used to be a boy, but as someone who's been through it, I know it isn't all fun and games."
"Yeah, I know, but I can use my powers to make things safer for me," Ty protested. Eileen had to admit, that was a convincing point. "Besides, now that we've both been both sexes, we know how strong the instinct to breed is, and how nice it is to act on it." She ran her hands along her soft stomach. "I used to be a boy and to really want to get to cum inside a girl and get her pregnant- now I'm a girl and I've had someone cum inside me, I wanna follow through on that and have his child. And you, you've been a woman and gotten to mother a child, but now..." She put her hand to Eileen's penis, still semi-hard and covered in a mix of their juices. "You can be a man and father a child."
Encouraged by his transformed body's masculine hormones and the girl he had fucked turning him on, Eileen was rapidly coming around to Ty's argument. She kissed him and he kissed back, his cock getting erect again even though they'd only just fucked. In his head he pictured the beautiful caboclo baby Ty would bear, a mix of his and her bodies' cutest features. "It's only natural," Ty assured him. "You as a man fucked me as a woman, and got me pregnant. I'd love to follow through on that if you're OK with it."
After some consideration, Eileen nodded. "OK, you can keep it," he smiled.
"Thank you," Ty replied happily, hugging him to her.
"I just have one condition," the Brazilian man added.
"Name your price," Ty agreed.
