As Ty kissed back, Eileen pushed Ty back down and let himself rest atop her. Their deep kiss continued for a little while, and once it finished, he whispered into her ear, "Hey Ty... are you up for having more of my babies?"
Ty blushed at the offer, aroused but a bit flustered, and mumbled, "I... I must've had, like, more than 20..."
"Good point," Eileen replied, getting up and off her. "If you don't want to fuck more, I understand!"
Seeing his handsome, dark, firmly-built body above her made Ty reconsider. As far as she was concerned, her lover was the hottest person ever to exist, and as intoxicating as she had been to him as a boy, as a girl she felt a somehow even more intense longing for him.
Her heart racing, Ty heard herself object, "I never said that!"
"Well, do you want me to fuck you again?" Eileen laughed, kneeling back down atop her. Ty nodded shyly as she felt his hairy chest press against her soft breasts, making her shiver. "I knew you would," Eileen purred, his words strikingly domineering. "In these bodies, I exist to mate and inseminate you, and you exist to get impregnated and bare our caboclo litters." Ty gasped and nodded more as her lover's phallus brushed against her skin.
"You want it this way. You could wish for something else if you wanted, you could wish to be a boy again and me a woman again, but you won't because you like being my paixão, my perfect babymaker. And you want me to make you bear life, endless life." Ty knew her lover was right, and as his cock head rubbed over her clit and pussy lips, she visualized the cycle- sex, fertilization, gestation, birthing, recovery- and a twinge of anticipation went through her.
Eileen kissed Ty's forehead and he asked, "How'd you like more of my seed inside you?"
"So bad," Ty replied, and with that she felt Eileen's cock part her pussy lips and pound in and out of her again. She wrapped her arms and legs round him and moaned as she felt him rail her eagerly, and his thrusts grew more and more forcible and intense as he continued.
Ty kinda felt like she was becoming more submissive to Eileen. She felt more comfortable in her female identity, and her enjoyment of this kind of sex and its consequences, so now she was able to indulge in the previously scary idea of his body 'claiming' hers through impregnation- it felt so good and she loved having his children, so now she had no problem with it.
Before long the thrusting of Eileen's hips grew more erratic and fast, and his gasps and pants flowed into Ty's ear, making her whimper and moan more in response. They came almost in sync, her pussy clenching around his cock while thick white semen began to splurt from his cock head and flow into her depths. They lay there, huddled together, slowly coming down from the high.
