Air controller

This air-restriction device is designed for sensory-deprivation and breath-control play. Built from materials selected for their seal and their comfort against the skin, it lets the dominant partner precisely regulate the submissive's airflow, creating a state of vulnerability and extreme focus.

The object's ergonomics ensure a stable hold and a reliable seal throughout the session.

Role in a session. The controller turns breathing into an adjustable variable. Programmed on cycles — here 1 min 30 then 2 min 00 — it alternates phases of flow and resistance with no human intervention, which produces a particular effect: it is no longer someone deciding moment by moment, it is a machine, and you can neither talk it round nor anticipate its next cycle. Every inhale becomes deliberate, counted. Combined with electrostimulation the effects stack: a pulse landing during a resistance phase layers pain over deprivation.

It is connected at the end of dressing, once the gas mask is on and the hose attached, and set before the sack is closed. It is one of the very last steps of the protocol, precisely because it must never be left running without the person being supervised.

Precautions. This is the most dangerous piece of gear in the collection, and it admits no approximation. The rule is absolute: air must always be able to circulate. You modulate a resistance, you never cut it off. The circuit must be physically incapable of closing completely, with a free emergency intake independent of the device. Check ventilation at the mask before continuing, monitor lip colour, breathing rhythm and level of consciousness continuously, and stop at the first dizziness, tingling or confusion. Never alone, never while altered, with a code of non-verbal signals agreed in advance since speech is impossible under gag and hood.

Care. Rinse the fittings in lukewarm water after each use, check the seals and the airtightness, dry completely before storage. A tired seal gets replaced: a leak falsifies the setting and makes the device's behaviour unpredictable.
