I.O.U. The Game of Hidden Pleasures
Once, twice, or as often as you like, you and your lover each exchange a hidden I.O.U. Share your erotic surprise with one another and follow the instructions to fulfill the I.O.U. Kind of like sexy coupon books-except you can't read them ahead of time! Spice things up by putting them in a fish bowl and drawing them out one at a time, or hand your partner one and ask them secretly!
