Orgasm Control

[PaulBlart]

I am extremely interested in having my wife control my orgasms. We played with this for a while, but it was mostly one sided. I would get her off with my tongue (our usual prelude to intercourse) and then ask her to tell me I couldn't have any. We'd end with her bringing me right to the edge with her hand or her feet (I also have a foot fetish) and then stopping. She would never say whether this appealed to her or not, but her sex drive seemed to soar while we were doing this. But, I needed for this to be out of my control and she was never willing to be active in controlling my orgasms, so it died out. I recently had the idea of proposing a game to her. we will have a bag with several white poker chips (maybe 5 at first) and one red one. She gets nightly foot rubs (she enjoys them and rubbing her feet gets me really turned on) and at least one full body massage weekly. She gets an orgasm (oral or fingering) any time she wants (she usually wants one at the end of a massage and sometimes after a foot rub). For each orgasm she has, I get to draw a chip from the bag. If it's red, I get to cum. If not, I don't. She can have intercourse if she wants, but I have to pull out before cumming and, if I masturbate or cum without "permission" all the chips plus one additional white one goes back in the bag so my odds of getting off go down. Has anyone ever tried this? How did it work out? Women (especially those not in to femdom and/or orgasm denial) does this sound appealing/interesting or at least not repulsive?
