We're going to spend a sexy overnight with a wonderful couple and rented a sybian for the occasion. My wife is notoriously "one and done" and we want to play with the sybian without killing her drive for more sex by causing a single massive orgasm.

Any suggestions for "games" or "dares" or other ways to incorporate the sybian for edging without just having the girls sit on it and get their rocks off while everyone else watches or plays with their tits etc?

The other woman is multiorgasmic so if you can think of other games or dares where orgasm is on the table but still incorporates some edging that's fun too - maybe a penalty of some kind if she can't last longer than x minutes, or where she has to beg to orgasm etc.

We're not BDSM couples but I guess this has some elements of gentle domination doesn't it...
