Breathing Challenge

This will be a harsh challenge for the slave. Queen Hanna and Mistress Jane have bet inbetween themselves under whose jeans arse the slave can hold his breath the longest. Mistress Jane takes a seat on his face and off we go! Queen Hanna counts how many seconds he doesnt breathe for. That was pretty good, but shes sure he can do that much better under her. After the slave has reached his agony threshold under mistress Janes butt, Queen Hanna sits down over his mouth and nose. How long will the slave endure .
