Natalie, heavy windpipe-crushing

Natalie has her slave on a stool with his head bent back so his throat is fully exposeed.

She sits fullweight on his throat, crushes his windpipe with her crotch and lights a cigarette.

While she sits comfortable like on a chair, she enjoys the noise of his heavy gasping throug the crushed windpipe.

After the cigarette, she moves on his face and cuts the air-supply completly.
