The slave is ready on the floor, Isabella steps on him, but she decides to make a more comfortable game... for her, not for him.
She let take a first smell of her sock, sits down on his belly and places the feet on his face.
Now, with both socks on his nose, the odor is intensive, because Isabella don't wear fresh socks for a footfetish session ;-)
She let him remove one sock with his mouth, then she places her bare foot on the sock on his mouth and nose, sock eating and smelling miam miam... fine!
After removing the other sock in the same way, she begins to play and squeeze his face with her bare feet....
