"I think I will have a bath," Sarah (in Jon's body) said. "Join me and tend to my needs."
Lisa (who had the mind of Jon) felt a tingling sensation coming from her crotch as she stood up. "Yes, Master."
They went to the bathroom, where Sarah undressed himself, revealing Jon's naked body to Lisa. Lisa had already seen it before, since she inhabited that body almost all of her life, but seeing it from her new point-of-view was weird, to say the least.
Sarah ran the water in the tub and then got it.
"Lisa, clean my penis," Sarah said, with a smile. "With your hands."
Lisa, having to obey her master, reached into the soapy water and grabbed hold of Sarah's penis.
