Smotherbox
Definition
A smother box is a BDSM piece of furniture or structure in which the head of the sub is placed in a fixed opening so that the dominant can sit on top of or over the face for controlled smothering. It is a form of breath play and face sitting that can only be performed safely within strict agreements and under constant supervision.

Explanation of smotherbox
A smotherbox is a specially designed piece of furniture that fixes the sub’s head in a stabilized, upward-facing position. The Dominant can then sit on top of the face or have the sub serve them via face sitting, without the head being able to turn away. This creates an intense form of surrender, dependence, and control, in which the Dominant has complete control over air supply, sight, and touch.
The smotherbox is often used in:
- facesitting
- breath control
- ass worship / pussy worship
- sensory deprivation (in combination with blindfolds or masks)
The setting is usually highly erotic and mentally charged. The sub experiences a combination of submission, tension, smell, body heat, and limited movement. For the Dominant, the smotherbox provides an increased sense of control: the sub’s body is accessible and the head is stable, allowing the play to proceed rhythmically and in a controlled manner.
Some smother boxes are minimalist – a wooden or metal frame with an open ring. Others are luxurious pieces of furniture with padding, adjustable heights, and anatomically shaped openings. What they have in common is that they hold the sub in a fixed position that invites deep surrender.
Safety & points of attention
Smotherbox play is one of the most risky categories within BDSM because it directly affects breathing. That is why safety is absolutely crucial.
Free airflow must always be guaranteed. Even in intense surrender, the sub should never experience complete airlock.
Use clear non-verbal signals. During smothering, the sub cannot always talk. Work with hand signals, taps, or agreed-upon body movements.
No alcohol or drugs. Both affect consciousness and reaction speed – both for the sub and the Dominant.
A smotherbox can be a wonderful combination of eroticism, humiliation, sensory play, and power. But only when the Dominant remains constantly alert and fully responsible.
