I thought it would be interesting if there was a new rule to the magical medallion. If you make a guy cum while your a female, you have to wait twice as long to change back. that's right, instead of 12 hours, your stuck in that hot female body for a full 24 hours.
"Mmmm, your cock feels so good in my pussy. Just don't climax ok baby?"
"Son of a bitch! Why did you cum? Now I'm stuck in this blonde bimbo body for even longer!"
"Hey! why'd you sneak that medallion on me? and why are you naked?"
"Fine, I'll lick your cock a little bit, but don't get too excited, and above all don't cum!"
"SON OF A BITCH!! I asked you to not cum! Now I gotta be a woman for 24 hours dude!"
