Bondage abandonment: leave him bound and waiting

Tying him up and leaving is a technique where the mind does the work, not the body. You secure his hands, add a blindfold — and go about your own business. He’s left alone: in the dark, unable to move, with no clock and no idea when you’ll return.

The first ten minutes he still holds on. By twenty he starts listening for every step of yours beyond the wall.
