Jane has her slave on a gym ball, ready for an education in breath-holding.
First she takes his airsupply with her ass, she sits on reverse his face, let his nose deep in her ass-crack...
There is no fresh air ;-)
After this, she controlls his breathing with hands over his mouth and nose (HOM).
Then he gets for reward a nice titsmother, may be here is the air better than in her ass-crack
It seems to be, that he needs to improve his breath-holding technique, so the game begins again in her ass-crack.
