Imagining setting up a special store where girls can buy rewards based on the number of edges they have done. The prizes would start out normal, maybe a nice dessert or stuffie. There would of course be the obligatory overpriced rewards that are too expensive to ever win by normal means as well.

Over time as the girl becomes more edged out and thinking gets harder, the shop would change. The normal prizes would disappear and be replaced by more... Interesting options. A slutty outfit, new sex toys, that kind of thing. The key is these prizes would help the girl become more horny and hooked.

As the girl goes deeper I would begin to offer bonus points for the store when the girl does more slutty things. Flashing strangers, blowjobs, sex, it would all get them closer to the big prizes.

And what would they be? Piercings, tattoos, body enhancement, things that would help the girl become a better slut. The ultimate prize at the end, once the girl had been edging for months and fucked countless strangers, would be taking her ability to cum away. By that point she would be too horny and stupid to argue.

Of course, there would still be a way to earn an orgasm. All she would have to do would be introduce one of her friends to my store.
