Yvette & Lena and their human seat

Yvette and Lena (ab)use their slave as a human seat, while they are making some lesbo-games. Yvette takes place on the throat of him and Lena sits on her lap, so he must endure the double weight on his windpipe and has Lenas nice ass near above his face, but cannot reach it. Several times they change places and positions, caressing and kissing each other, and their slave gets seriously flattened under their double weight.
