【乳胶男M】TAG：呼吸控制、行李箱‘润滑牢’。注：此场景是在受控条件下拍摄的。像这样的约束和呼吸控制是极其危险的，甚至可能是致命的。不要尝试！Our friend Rank is always on the lookout for new and novel ways to confine his rubber gimps. This time he utilizes a rigid fiberglass military box with custom ports for passing both inhale and exhale breaths generated from the subject inside. The ports are connected via rubber hoses to a dual-cylindar bubbler bottle which allows Rank to fully monitor his subject's breathing. For extra fun, Rank pours 5 gallons of J-Lube inside the box before sealing the lid. This is a highly unique scene which many rubber and confinment fans fantasize about. NOTE - this scene was filmed under controlled conditions. Confinment and breath control like this is extremely dangerous and possibly fatal. Do not use this scene as a guide or suggestion for your own play. If you play with confinment or breath control do so at your own risk.
