Anastasia steps over her slave, decends slowly her ass to his face, so he can see, that she has nothing under it ;-)
But this was the last view, she drops down and her ass fits tight on his face, the nose deep in her ass-crack.
Lick!... Lick!...
For a little break inlicking, she moves slightly forward on his throat and let him little breath, might be difficult with her weight on his windpipe.
Then it's again time for licking... moving and dropping back on the hungry tongue....
