Tease and denial is arousal plus a withheld climax, on purpose, as the game. A partner brings someone close and parks them there. Chastity devices can lock the rule in hardware. Hands and timing can do it with no hardware at all.

The erotic charge is frustration. Too much frustration becomes irritability, numbness, or a fight about dishes that is not about dishes. Agree on duration. A weekend is not the same product as twenty minutes.

Orgasm on a timer the other person owns requires trust and an exit for pain, panic, or a sudden sad mood. If denial is used to punish a real-life mistake, you have left play and entered scorekeeping.

When release is finally allowed, do not add a new surprise rule in that second unless it was already on the menu.
