Masturbating with sniff dildo

I'm wearing full heavy rubber with a gas mask and filter. But than I decide to change the filter for a sniff dildo. The dildo is connected with thhe gas mask by a long tube. There are only a few small holes in the dildo which allow me to breathe. The further I enter the dildo inside of my pussy the less I can breathe. So I need to choose between breathing and satisfying my needs for sexual pleasure. I can smell how wet and horny I am because the air I breathe is literally going my pussy.  I'm going more and more into it and finally reach a few strong and intense orgasms. This is rubber heaven to me.
