Rebecca recovered pretty quickly, and got herself off Ty, seeing her thick loads of cum slowly leaking from his pussy. "Fuck, that felt good," she breathed. "Um, Ty?"
"Yeah?" Ty asked, still in a post-orgasmic haze from being fucked up so hard.
"Is, um... is it OK if we stay like this for a day or so?" Rebecca asked.
"Yeah, sure!" Ty replied, looking up over his new weights to smile at her. "I can wish all our friends and family think we're the sex we are now until we turn back if you like."
"Sounds good," Rebecca agreed. And Ty wished it. A little shiver ran through them as they realized it had taken effect. "You know," she said, realizing Ty would probably need to get back home soon, "I think it'd be nice if you came back before we change back, if you know what I mean."
"Definitely," Ty grinned, and after cleaning the juices from his pussy, he dressed in some of Rebecca's clothes and handed his to her so she could dress in his. They kissed, and their kiss quickly went from a peck on the lips to full-on making out and feeling each other up. Once they'd come to their senses, Ty slipped out of the house, heading back to his own.
That night, neither of them could focus on anything but how bad they wanted to fuck each other again. After dinner with her mom, Rebecca rushed off, locked her door, and pulled out her cock to start jacking off again. She found herself looking up pictures of hot girls, big boobs, soaked pussies between spread legs, imagining getting to fuck their throats and tits and butts and pussies with her big thick cock. Remembering how she'd filled up Ty's pussy, felt his body cling to hers and milk the cum out of her, only turned her on more.
Next door, Ty did practically the same thing, rushing off as soon as he could after dinner to go and play with his new parts. His interest was now solely in men- firm thick bodies, long hard penises, and thoughts of forcefully being filled up by a cock. One hand rubbed and massaged his clit with the thumb while fingering his pussy, the other played with his soft breasts and squeezed the nipples firmly. He soon started looking up pictures of darker-skinned cocks that looked like Rebecca's, and remembering how lustfully she'd pounded him and cum inside his pussy to fill him up.
Neither of them could wait to actually fuck again.
