It's all about submitting yourself and your trust in Me. There is nothing that tests that better than tying you down and putting an air-tight gas mask on your face. Sitting My perfect, latex-covered ass on your chest during this makes breathing hard enough, but then covering the hose, your only access to the life-giving air makes this game all the more fun. Now the fact that I put the hose between my round breasts and between my long legs, don't let that fool you, this is all about My pleasure...
