Our appearance is breathtaking, but what we will do to our slave is also breathtaking. Strapped down and blindfolded, we take away his senses. With our beguiling voices, we penetrate deep into his mind. He is at the mercy of our total control, whether with a latex cloth or a gas mask. Bit by bit, he finds it harder and harder to breathe and his huge cock becomes stiff with lust until he is finally allowed to cum at the climax to show us his devotion.
