Tammy felt amazed as she realized what Ty had just managed to do. "I'm... I'm pregnant," she breathed.
"Yeah," Ty replied. "Like it?" Tammy nodded, grinning in amazement, and Ty kissed her. Once she broke the kiss, she had another crazy idea. "Hey, Tammy? How'd you like it if you could just get bred as much as you like, even when I'm not around?"
"That'd be so good," Tammy replied.
"Then I'll try another wish," Ty purred. She focused on the slightly elaborate idea: make it so Tammy gives birth in 9 minutes instead of 9 months, doesn't have any pain in birth, and her child ages to Tammy's age after suckling from her.
Tammy shivered as she felt Ty's wish alter her body, and her belly and breasts slowly swelled. "Wha-" she began, but then Ty kissed her head and wished for the knowledge of the wish to transfer into her head. "Ohh," she grinned. The girls watched in anticipation while Tammy's child grew inside her, and her breasts leaked milk as they prepared to be able to feed it.
After a few minutes, Tammy felt the muscles in her nether regions contract and slowly push her offspring out. Ty held her hand, but to her relief she didn't feel any pain as her body neatly widened to birth the child, and when Ty held it up to her she saw a perfectly healthy baby boy. Something about him was kinda familiar, but otherwise he looked beautiful.
Instinctually she brought his head to her bosom and he sucked at her nipple, and as he drank she slowly realized he seemed to be growing. Once he pulled his mouth away, she had to put him down, and saw him age into a young man. He sat up, and Tammy saw her child was... him.
"You're... a clone?" she said slowly.
"Yeah," Tim said. "I'm identical to you before you changed, since I came from your own sperm and your own egg."
Tammy was surprised that she found his modest but toned figure and lithe but firm muscles and the erect manhood between his legs so attractive. She didn't even notice Ty wish away the remnants of her birthing as Tim took her face in his hands and kissed her passionately, kissing back without any care for how weird this was.
"You two have fun now!" Ty chirped, both of them looking up at her as she hastily dressed and showed herself out.
Once she had left, Tim positioned himself atop Tammy and the two felt their hearts racing as they straddled each other. "I bet I know what you want," she heard him say.
"What do I want?" she replied huskily.
"You want to use me as a fucktoy and get bred by me," he purred.
"Fuck yeah," Tammy agreed. Tim pushed his thick cock inside her and she moaned with satisfaction and wrapped her arms and legs round him as his hips thrust in and out of her at an unstoppable pace.
"You're so fertile and horny, I bet you're gonna birth even more clones to fuck you," Tim groaned into Tammy's ear. She agreed, the idea of an orgy with the clones she birthed was pretty enticing.
Eventually she hit her peak and clenched tightly around Tim, and heard him pant deeply and felt his warm cum splurt inside her. And sure enough, an ovum was inside her which his sperm surrounded, fertilizing it and making her pregnant all over again.
