Breath play fantasy is a type of erotic or sexual fantasy that involves the deliberate restriction of airflow or oxygen during sexual activity. It encompasses a range of activities where one partner restricts the breathing of the other, either through manual pressure, choking, suffocation, or the use of restraints such as collars, masks, or plastic bags.

This fantasy can take various forms, including:

  1. Choking: Applying pressure to the throat or neck to restrict airflow, often using hands, ropes, belts, or other objects.
  2. Suffocation: Blocking the nose or mouth to prevent breathing, which can involve covering the face with hands, cloth, or a mask.
  3. Breath control: Using techniques to control or manipulate the breathing of the submissive partner, such as breath-holding, forced inhalation or exhalation, or controlling the pace and depth of breathing.
