Mayuko (pseudonym), who was captivated by anal pleasure from a young age and repeatedly engaged in anal masturbation alone through elementary, middle, and high school, decided upon graduating from university that she couldn't continue like this. She sealed her anal desires and chose the path of becoming a female teacher to live as a normal woman. She married a man she was destined to meet and was blessed with a daughter. However, her innate abnormal anal masochistic tendencies could not be suppressed, and eventually, Mayuko began to secretly repeat anal masturbation in the toilets at the elementary school where she worked. This was discovered by a parent, Mr. N. The video captures such a Mayuko, an A maniac, being tormented in her anus repeatedly by Mr. N, a sadistic man with the same A maniac tendencies, in a series of niche scenes. The main recorded content includes anal orgasms, anal speculums, insertion of foreign objects and defecation shows, lesbian acts with female college students who were her students, continuous anal orgasms, budding anal roses, SM orgies and swaps, extreme thick dildo A torment, anal plugs and whipping.
