I badly wanted to find a way to use my gasmasks underwater, so I created an adapter to attach my vintage dacor scuba regulator to any standard 40mm gas mask intake. In this clip I'm trying this rig for the first time, with a beautiful Chinese industrial gas mask. While I still prefer a regulator mouthpiece over a full face mask for scuba, I still manage to quickly find myself aroused. As always I cannot contain it so I end up fingering myself to climax... after which I continue my equipment trial as if nothing had happened...
