Yvette Costeau, fullweight Facesitting on the bench

The slave is lying on the high bench, ready to be the seat for Yvette. 

So she sits foreward on his face, mostly with all her weight, because the bench is so high,

that her feet nearly don't reach the floor, means they are mostly in the air and the hole weight is pressing on his face.

Then she turns around and sits reverse, his nose deep in her ass-crack!
