One partner tied up, wearing a blindfold and noise cancelling headphones. The other partner is then in charge of pleasuring the deprived.
For the deprived, it is very intense as you are giving yourself fully to your partner and entrusting them to bring you pleasure. You can’t see, you can’t hear and you are tied up so you can only move as far as your bindings allow. The anticipation alone has brought me to orgasm.
Side note: make sure the music in the headphones is conducive to the situation.
