Daliah loves feetgames; she has her slave trapped in a hole in the floor, he cannot move away even turn his head is impossible... ready for to be stepped on.
In the beginning, Daliah plays with her feet on the face, squeezes it gently, like a massage. She tries to cut off his air-supply with clamping his mouth and nose between her toes.
The she stands up and begins to step on the face, squeezing it now under her full weight... still a massage?... more fullweight stepping and walking on the poor face... hard massage = good massaage ;-)
