Pleasure for two?

He thought about it for a long time. Suppose he wished that her body would change to his innermost desire whenever they had sex? Perhaps he could change his body as well? What if he made her cum alter him to her innermost desires as well? They'd be perfectly matched.

Yes. He decided. He would wish for her to change to his desires, and for him to change to hers. He swallowed hard. Suppose she wanted a sissy cuck? Damn. Maybe he would wish for her desires to change a bit too?
