More About Water Bondage
Water bondage can involve spraying, dunking, water cages, water boarding and other types of play. Spraying is usually done with high pressure and has the same effect as spanking, flogging, or caning. In softer forms of play, a shower head can be used. Dunking is another form of erotic asphyxiation where the submissive is dunked under water and forced to hold their breath. In a professional setting or exhibition, a Houdini tank is usually used.
