Daliah: How long? Breath-hold-training!

Daliah enter the room with her slave, who is on all 4s. She chains his hands at the bench, so he cannot move and is ready for the breath-hold-test. She sits in several positions on his face, mesuring the time, he can be without air-supply. No it isn't perfecct! he needs a lot of breath-hold-training.... under her ass ;-)
