The guys at Serious Bondage love testing new gear here is smokin hot Bruin in the awesome new GA-4 full-enclosure rubber suit from StudioGum. He wears a gas mask inside the hood of the suit, which has a pass-through fitting allowing him to breathe outside air. Once he is fully sealed into the suit, they suck all the air out. Further experimentation is required to achieve total immobilization, but hey, theyve got the time.
