Director Nampo Masaki teams up with gifted dominatrix Nao Jinguji for a merciless display of facesitting. Submissive men are pinned beneath her thick, premium ass and sweaty pussy, their faces treated as nothing more than a queen’s chair. Used as suffocating human vibrators, their breathing and orgasms are controlled as Nao smothers and grinds them into overwhelming, near-unconscious pleasure.
