Yvette and Adriana are wearing tight blue-jeans.
Yvette want to show the newcomer Adriana how to flatten a slave under double weight.
They start with sitting on his body, but soon Yvette changes on his face, showing Adriana, that here is also a good place for sitting.
Then Yvette sits on Adrianas lap for increasing the pressure on him, he's moaning because the weight on his chest, but this shows the girls, that he can still breath under the double weight.
Later, Adriana sits on his throat.... and Yvette settles again on her lap, now their double weight is on his windpipe and face, no breathing and a good facecrush under hard blue-jeans.
