Sumika (Kanade Free), a married woman fascinated by a strange pleasure that she could never experience with her husband, is trained in anal sex by a certain S&M maniac, and has become a perverted wife whose crotch gets wet even in pain that makes her organs turn inside out. Sumika writhes her bound and crippled body as she climaxes with vegetables being forced into her two holes, and cries in shame as she is watched excreting bananas. She is hung by a nose hook and raped, with her nasal mucosa stimulated. Her pale skin is whipped violently, and hot wax is mercilessly dripped onto her swollen skin as she is tortured. She is forced to deep-throat to the point of suffocation, and then has shocking anal sex that makes her climax repeatedly with pistons so hard that her intestinal walls turn inside out. When she finds pleasure at the end of unimaginable pain, Sumika is liberated to the height of sexual pleasure that transcends morals.
