She heads out with you in her panties and has to try not to cum

"A game," you say. She pulls back from you and raises an eyebrow. You nod, and turn towards your equipment chest. You fish out your vibrating vest and gloves, and turn back to face her. "I'm going to get in your panties and do whatever I want. You have to go out in public with me in there. You cum, you lose."

Jane flashes a wry smile. "Sounds easy. What will I win?"

"I'll go home with you every night for a week" you say.

"That almost sounds like a prize for you," she teases.

You put your hands on your hips. "And I'll let your friend have a session, free of charge." The words have barely escaped your lips before she sweeps you up, leans back in her chair, and spreads her legs. You get a great view of a wet spot on her panties, her vagina, and a cute tuft of red hair before you're hit with the familiar shocking warmth and wetness of being pushed up against a hungry pussy. She slides you up until your shoulder brushes her clit, then down, and then up again, settling you neatly in her labia. You have enough time to notice her clit right next to your head before you're put in semi darkness with a snap of her panties.
