The mistresses put on their jeans and start sitting on the slave’s face, smothering him so he can’t breathe. His nose and mouth are completely covered by the mistress’ jeans.

After his face gets red, one mistress gets off and the other gets on, smothering him more and more with their tight jeans. The best material for smothering while sitting on a slave’s face is jeans because there is no way that any man slave can breathe through the fabric!
