骑脸盒压脸，面对蹦床，屁股和阴户摩擦脸，脸被绑在屁股上并被带散步

The masochist has his head put in a facesitting box and lies there with only his face sticking out, unable to escape. The mistress comes over, looks down at the masochist with a grin, then drops her ass on his face and sits down, crushing his face with her ass. Mistress jumps on masochist's face with her ass repeatedly, lands on it, crushing his face and saying "What a nice chair, hahaha." Mistress stands on masochist's face with both feet, crushing his face with the soles of her feet and smiling. Mistress uses masochist's face as a trampoline, jumps with her feet, lands on his face, crushing it with her feet and grinning. Mistress ties masochist to a pillar and rubs her ass and pussy on his face, saying "Memorizing the smell of the mistress's ass and pussy is a must for a slave, hahaha." Mistress fits masochist's face to her ass, ties him up with rope, and says, "Let's take a walk, hahaha," and the masochist has to follow her on all fours, along with the mistress's ass.
