Rules are rules, baby!

"Sorry love, cant take back a wish! Those are the rules!"
Sarah gasped as the true impact of her wish struck her. Jon was now and forever a pair of pink panties.
"I'm... I'm sorry, Jon." She was close to tears with guilt.
"Well, that's okay, but can you do me a favour?"
"What?"
"Let me back in your pants!"
With that the crazed piece of clothing snaked across her body, down over her legs and back up to her groin, fitting snugly in their rightful place. Reluctantly, the emotionally exhausted Sarah put her pants back on, hearing a disturbingly content sigh from Jon.
"This... this is really wierd."
"I think I could get used to it. Life is a constant struggle to meet hundreds of demands and satisfy hundreds of desires. Right now I only have 2 desires, your crotch and your panties. So long as those are fulfilled, I'm in heaven. And I think it's only fair that I return the favour."
"What are yo-"
Sarah's knees shuddered as waves of pleasure eminated from her groin. Jon was using his soft pink fabric to manipulate her clitoris lips with expert care, stretching up inside her and teasing the clitoris itself. Sarah tried to compose herself, but the pleasure was too powerful. Within seconds she was lying on her back, writhing and screaming in extacy.
