You demand that your slave ties his ankles to a chair, blindfolds himself, and edges three times while he imagines your wet pussy. You demand that when he reaches each edge he is to say "My cock is yours to use, Mistress. May this worshipful edge please you." He can remove his blindfold when he completes his last edge, but you decide if he should stay tied up until you're feeling like letting him go...whenever that may be.
