Water-bondage
Water-bondage is a BDSM practice that involves the use of restraints and other bondage techniques to immobilize or restrict movement in water. This can include tying up the submissive partner underwater or on or near the edge of a pool or tub, leaving them partially or fully submerged, sometimes with their head above water so they can breathe. The lack of traction provided by the water makes it harder for the bound individual to escape or even move much at all, adding to the power dynamics inherent in BDSM play. Water-bondage also introduces sensory stimulation from the coolness or warmth of the water against the skin, as well as the feeling of weightlessness or buoyancy that can amplify the sensations experienced during sex or other erotic activities. However, due to the potential risk of drowning and other safety concerns, this type of play should only be performed by experienced practitioners who are skilled in aquatic rescue and emergency procedures.
