Carefully pulling himself out of and off Ty, Eileen whispered to her, "You're such a good girl, paixão." Ty blushed, and she felt her lover's warm cum leaking from her freshly mated pussy, still transfixed by his body. "You know what I'd love to see, though?" Eileen asked. Ty shook her head. "I'd love to see your body once it's swelled up with our caboclo babies."
To Ty's surprise, the idea aroused her a lot too. As a boy, he never could've imagined any of this might happen to him, and now it could, and with someone she felt so close to no less, she felt desperate to indulge it. "I-I think I wanna do that now..." she heard herself admit.
"Do it, then," Eileen begged. How could she turn down a request like that? She wished for her body to advance 9 months, and that her pregnancies would not harm her and would be healthy.
Sure enough, she saw her belly slowly expand. Her stomach swelled, and soon distended as it became clear she was not carrying a single child as was normal. It grew wide and large, her navel popping out and stretch marks appearing like tiger stripes across her skin.
Her breasts were also swelling, filling with milk and enlarging to stay at least a little in proportion with her pregnant belly. She gasped as she felt them grow tingly around the nipples, and saw milk leak from the teats as her body began to lactate.
By the time Ty's body finished changing, the foetuses inside her had grown so numerous and so large she couldn't even stand. This felt far beyond any normal pregnancy- she felt claimed by Eileen's seed and the offspring it had managed to create. She could even feel her unborn children moving inside her, and occasionally the outline of a hand or foot would emerge from her soft flesh for a moment.
Eileen, on the other hand, was enjoying an instinctive primal pride. This young woman would soon be bearing their caboclo family, and he knew they would be beautiful. He felt so proud of her for carrying this load so bravely, and in a way proud of himself for managing to pass on his seed to her.
It would not be long before Ty bore life.
