Eileen's cock slowly pulled out of Ty, his thick white juices oozing from her pussy as she gasped for air. It surprised her how at ease she felt with this man impregnating her, especially considering he had made another baby with her only minutes before. But his body just enthralled her- his toned muscles, his bronzed skin flecked by bristly masculine fuzz, his handsome and satisfied face, his thick manhood coated with her translucent juices and his gooey white essence, his balls which she knew were producing far more of that essence. He just seemed so ideal for breeding with.
She barely noticed how he'd leant into her ear until he sultrily said, "Ty? Please, birth my next caboclo baby."
"O-OK," Ty agreed, wishing again for the fertilized egg inside her to develop into a child. She saw in her head how it developed into an embryo and a foetus, the features it had inherited from its mother and father emerging, most obviously its mixed skin tone, but also hints of her and Eileen's facial features.
Ty got distracted from their offspring's development when she felt Eileen's dark hand rub over her swelling baby bump, and he teasingly said, "You know something? Since I've put more babies in you than I ever birthed, I kinda feel like I'm more of a man then I ever was a woman. I wonder if you feel like you're more of a girl than you ever were a boy?"
Ty gasped and felt her breasts tingle and start to lactate- her offspring's gestation and her arousal were weirdly intertwining. "I d-do," she said. "I never really let myself think it, but... I really wished I could get pregnant when I was a boy." She realized once she said it that that was true.
"And now you've been castrated, emasculated and feminized, you are getting pregnant from me mating you," Eileen agreed. Ty felt herself moisten, her slit making his juices flow away to clear her passage for her baby. "When you were that horny teenage boy, you must've milked yourself countless times, your fertile sperm fated never to make a baby- but I, as a man, will make every load of my semen go towards making you pregnant!"
Ty felt something pressing against her tummy from within, and realized their baby was kicking. She recognized that it would soon be birthed as it grew and grew. Soon her water broke, and Eileen held her hand as her birth canal gradually spread itself for her to deliver the offspring.
It emerged from her loudly crying, and Eileen passed it to her so she could nurse it. Its cries faded as it suckled mother's milk from her, and she lay it down to sleep next to its sibling.
With that done, she wished herself back to virginal proportions and turned to her handsome lover and his throbbing dark erection again...
