These first two photos I am actually upside down, with a gas mask and then switched to a hood with inflatable gag. I'm enclosed in my second skin (see relevent page) and the rack itself can be spun through 360deg.

These next two, I am bound, arms aloft and subject to a restricted breathing gas mask. This is in preparation for suspension with an inflatable hood and breathing tube. The reason for the preparation is that the inhale and exhale through a hood tube is through the same tube, not separate as in a gas mask. There is the danger with a long single tube of re-inhaling expelled air leading to oxygen deprivation.

Similar to this is the breath control water tank. The mechanics of it are a secret, but it does lead to air deprivation (which can be controlled by Mistress). Quite an experience over a period of time, especially when also enclosed in three layers of rubber and strapped securely to the bondage bed

Water punishment: encapsulated within a latex skin and with five lengths of air line, I am submerged in the bath. Note Mistressess rubber booted foot and rubber apron hem.
