With the help of a slap with a leather belt, Stefanie orders her slave to lie on his back on a stool, right for to be her sitting-toy.
She steps over him and with a big "Ummmpf" she drops down on his chest, a little martyrium under her 165 lbs can begin.
She clamps his head between her strong legs, teases him with the belt in the face, closes his nose and mouth with her hands, only for to make his air-supply more difficult.
The it's time for moving on his face, no more oxygene for him.
He begins to struggle and squirm and finally he drops her off and they both fall to the ground...
But he isn't free, because she takes his head immediatly between her strong legs in a scissorhold.
