Eileen slowly withdrew from Ty, and the two saw his thick cum leak slowly from her pussy. "That felt so good," he breathed. "Thank you, Ty. I'm really glad I got to experience that. But... can you change us back now?"
"Are you sure you want to go back so soon?" Ty asked.
"Yes," Eileen replied, surprising her with his assertiveness. "And you need to," he added, looking down to Ty's crotch. "I know it's fun to have sex like that, but I don't think you're ready to actually be pregnant."
"I guess you're right," Ty agreed. She wished for them to turn back.
Sure enough, their bodies started to reconfigure back to how they had been. Eileen's thick, hairy figure receded back to soft curves and smooth skin, and his muscles turned lithe and petite. His firm chest expanded out and his small nipples grew pert and large, restoring the gorgeous breasts she had always had, and the cock that had just fucked Ty senseless rapidly shrank away while his balls pulled up into her body, forming her subtle vaginal mound and clitoris. She looked exactly as she had before she turned into a man.
Likewise, Ty rapidly transformed from a girl to a boy. Her cute curves straightened up and her figure filled out, her muscles growing slightly larger. Her soft breasts shrank into her pecs until she had a flat chest, and her vaginal slit sealed up. Her ovaries rapidly transformed back into his testicles as they slid down inside the sac that had formed between her legs, and her clitoris elongated and thickened until it formed a phallus again. He looked identical to how he had before he changed too.
As they finished turning back, Eileen leaned forward and kissed Ty eagerly, and he kissed back.
