The slave is leaning at the sofa, ready for receiving an other lesson without air und Daliah's round ass.
Immediatly she sits down on his face and seeks the position, which seals his air-supply propperly.
When she wiggles her hips, his nose drives deep and deeper in her crotch and ass, a warm world surrounded with soft flesh.....
but NO AIR!
He has to suffer under her weight, while she enjoys the feeling of the face in her ass.
