The smotherbox, a device designed to limit oxygen intake for a short period, is introduced with a thorough explanation of its use, safety precautions, and the predetermined safety word. The submissive partner is placed in the smotherbox, and the dominant partner controls the experience, demonstrating trust, control, and care.
This device serves two primary functions: comfort and intensity. For the dominant partner (the "sitter"), it provides a stable, comfortable edge, removing physical strain. For the submissive, it locks them into a position of total surrender, turning facesitting into a dramatic, high-intensity form of breath control and sensory deprivation. video title facesitting smotherbox femdom ho
