Once he broke the kiss, Eileen asked, "Now, can you birth our calves, paxião?"
Ty shivered with a weird, shameless pleasure at hearing him call their offspring that. Treating their mating as something animal was arousing as fuck to her. "Of course, my stud," she grinned.
She felt his phallus and gonads twitch against her skin, as if calling Eileen that made his body ache to knock her up still more. In fairness, she wanted that just as much as him. "Fuck, you are so perfect for breeding," he breathed.
Her heart raced as she wished for the swathe of fertilized eggs inside her to gestate, and as Eileen sat up, he and Ty saw her swell up again. Her stomach steadily distended and her skin became flecked with stretch marks, while her breasts dripped milk off their teats.
To her surprise, Eileen put his mouth to her nipple, and she moaned as he sucked some of the milk that would feed his caboclo babies. After sitting up, Ty saw he still had an erection, and he confessed, "I hope it's not gross to you, but... when your body swells with our litters, it's really hot to me."
"Th-thanks," Ty mumbled in surprised pleasure.
"I kind of wish I could rub myself off over you, but I don't want to spread my seed anywhere except inside your pussy," he continued. Eileen's confession was simultaneously kinda hot and kinda sweet to Ty, and made her ache to have him mate her more.
Soon after, she felt her water break, and to her relief Eileen diligently rushed to her pussy and helped prise their calves out into the world, handing them to Ty so she could position them to suckle on their mother's breasts. It surprised her just how many she had to nurse, and how readily her milk flowed from her.
Eventually, she finished bearing them and they had all been laid down to sleep comfortably. Once that was done, she wished for her body to elastically return to its pre-pregnant state again, and pulled Eileen in close to kiss her.
