Kelly had cleaned up the mess he made and was now luxuriating in a long, hot shower during which he soaped every inch he could reach of his magnificent new body when he heard his roommate coming in the apartment they shared. He knew that she would now know him as a man due to the wish he had made earlier, but hadn't really thought about anything beyond that. Kelly found his mind dwelling on Maria, her luscious brown body and curvaceous breasts and butt, when he noticed two things--now that he wasn't locked inside one, the female body didn't disgust him at all and his new penis was once again hardening.
He was drifting off into an erotic haze when he felt a gentle touch on his new male organ. A naked Maria stepped into the shower. "Mmmmm" she said "Looks like someone was thinking about me."
The ring, as was its wont, had taken the path of least resistance, and made the new male Kelly and his female roommate lovers.
