After Anna Petrovna and I have oiled each other's latex, we are ready to play with the slave in the black box! We control his breathing. We are the ones who decide how much oxygen he gets. We allow or forbid him to breathe. As a reward, the slave is allowed to lick our boots and then has to offer up his holes for our strap-ons! The virgin gets fucked anally! Because he bravely offers up his ass for us, we let him cum as a reward.
