I want to train My slave to be a good ass cushion for Me tonight; I love face sitting very much, and I like My subjects to be able to stay very long under My ass. First, I want him to get accustomed with My weight, so I sit on his chest. Next I move on his face, smothering him, making him understand that his breathing is not a priority for Me. he should get used with the idea that he is just an object under My ass that I don't care very much about. In fact, when I feel some farts coming, I have absolutely no problem releasing them right in his face. I'm not ashamed that he can hear and smell them, one can't be ashamed of an object. And he can breathe them if he wants to breathe so much. But what I want is to train him not to disturb Me with his need for air, and I have just the right method for that. I take his chastity device off and start rubbing his cock: as long as his face is under My ass - My hand is on his cock. When he wants air - I stop rubbing, thus stimulating him to stay longer under My ass. Suddenly I feel that My slave's cock becomes ready to explode, it seems all that time in chastity and this proximity to My ass made him lose control so much that he is going to cum without My permission! he may do that, I can't stop it now, but I will make sure his orgasm is ruined, and even though he shoots the cum straight up, he will not feel any pleasure. Quite the opposite, all he will feel is pain, from the post-orgasmic torture that I will punish his insolence with.
