Julia-Eva's breath-hold training

Today Julia wants to improve the breathholding capabilities of her slave, she wants train him for to be a good seat for her.

She has him on the mat, steps over him and decends her big ass right on his face and starts the stop-watch.

Her ass is so big and soft, it fits best with his face, sealing properly his air-supply, means best training conditions.

But he is weak, after a little time he runs out of air, Julia don't like this so the training must go on.

Also foreward sitting, she has total control over him... he only gets a little sips of moistured air from he crotch.... or nothing ;-)
