All slave gets to do is sniff my ass.. His mouth is gagged and wrapped, and only his nose is exposed..  I make sure his nose is right against my asshole the entire session..  I start with a 2 minute timer, and sit on him with all my weight until the timer runs out..  Then each round I add a little more time, and then more, and more.. Hehe It doesn't take long before he's struggling for air, which he can only breathe directly off my asshole.. And yes- I did not shower for 3 days before shooting this video to make sure my scent was nice and strong for slave..
