Jeans Butt Breath Control For The Slave

The slave can do absolutely nothing if I sit down with my jeans butt on his face. His head is stuck in this box for this purpose. Its simply ideal for tormenting him with hard facesitting. How long will he be able to sit under my hot arse with no air?! Ill test it, controlling his air supply with my jeans booty. I alone control his breathing and he is now learning to give up control of his life to me.
