Yvette (ab)uses her slave as he seat, while she does her daily things like hair-brushing and so on. This time she dont want to sit on his face, because there are to much interuption because his struggeling when he runs out of air. He's lying on his back, his head is outside of the stool and bent back so his throat is fully exposed..... right for Yvette to sit on. Now he should be quiet and she can do her hair. She cares, that she sit very close to his ching, putting all her weight on his windpipe..... his head gets bent back like she wants to cut it like a guillotine.
