Well, OK

Tom rubbed the coin and made the wish: "I wish my wife were a red hot masochist who gets sexually excited by degrading and painful treatment and who loves it when I hurt her during sex, or when I order her to hurt herself, or even when I let someone else hurt her."

Time to try it out. Tom finds Sarah in the living room watching television. He grabs her by her ponytail and forces her to the floor. "Kiss my feet," he tells her. A look of shock goes over her face, soon replaced with a look of astonished pleasure. Without a word, Sarah kisses his bare feet and rubs her face all over them.

"What's gotten into you?" Sarah asks. "Not that I'm complaining, mind you. It's really hot!"

"I used the coin to turn you into a masochist who loves degradation and pain," Tom tells her.

"But we didn't talk about that!"

"I know," Tom said. "I didn't think you'd agree but this is what I decided to do and I think you like it. Tell me if your pussy's wet."

Sarah put a hand down her pants and felt her pussy. "It's sopping," she admitted. "But why didn't you ask me first?"

"Because if someone picks their own degradation, they're not really being degraded, just play acting. I want you to be truly degraded and still love it, against your will."

"Damn, that's so hot," Sarah admitted. "My scalp is tingling where you grabbed my hair. It's almost like my scalp is another sex organ!"

"Wait till I do your tits," Tom growled.
