Reality irised back in on Ty as she felt Eileen pulling out of her pussy. Soon she was leaking different kinds of milk in different places- her mother's milk dripped from her big soft teats, and her lover's milk ran from her pussy, more than enough inside her to make as many more babies as she and her lover desired.
Eileen leaned down so his mouth was by Ty's ear, and whispered to her, "I know how you can make yourself an even better breeding cow."
Ty felt a shiver run through her as she heard him call her that again. She felt like he could tell her to do anything and she'd do it. "Wha-?" she answered breathlessly.
"Give yourself some more breasts for our babies to suckle from," Eileen instructed.
Ty gasped and wished for it. Warm tingling sensations spread in pairs all the way down her stomach, and teats to have suckled on emerged from her skin. They pricked up and grew larger, and Ty whimpered as soft mounds of flesh began to sprout down her belly. The weirdness of the sensations intensified as Eileen's firm hand reached under her to cup two of her freshly-formed tits, even moreso when she felt his erect manhood rub at her again.
Tampering with her human physiology made Ty feel weirdly... animal. Especially considering she'd just birthed an absurdly large litter of children for Eileen. And yet, she loved how it felt.
She wondered what Eileen would do next...
