Anastasia, easy facesitting and slave-teasing

Anastasia binds her slave on a little bench and decends slowly down on his face, she sits there for a wile, enjoying the feeling of a face under her ass.
Then she moves back on his throat closes his mouth and nose with her hands (HOM), and tests his ability to hold his breath.
In the second half of the clip, she turns around and sits reverse on his face, mostly fullweight, so his face is deep in her asscrack.
