Mistress Mercedes has defined requirements for her slaves. Being her living ass cushion where she can place her ass on is one of the most important. She wants the slave to smell her ass and he has to know where his place really is! In between he gets further punishment with hard slaps. She even sits down on his nose with her full weight and he has to endure it! The longer she sits on him the hotter it is for Mercedes and the more she presses her ass on his face!
