Yvette and Adriana want to flatten the slave with maximum of weight.
Yvette sits high on his chest and on his throat, first Adriana takes place behind her, but soon she climbs on Yvette's shoulders, now it gets heavy for the poor slave under.
With more than 130 kg (286lbs) on his throat is breathing nearly impossible, Adriana moves her feet on his face, lowering the pressure to the throat a little bit, but she cuts off the airsupply with her feet.
They change places, sit on his face, burriing his nose in the ass-crack, Yvette also steps on his face, while Adriana sits on his throat....
