Since childhood, Mayuko (pseudonym) has been obsessed with anal pleasure after secretly watching her elderly aunt defecate outdoors. From elementary through high school, she repeatedly engaged in solo anal masturbation. After graduating college, she realized "this can't go on" and resolved to suppress her abnormal anal desires, choosing to live as an ordinary woman by becoming a teacher. Eventually, she married and gave birth to a daughter. However, her innate anal masochistic urges could not be fully suppressed, and before long, she began secretly performing anal masturbation in the school toilets. Her actions were discovered by a parent, N, who then forced her into accepting various humiliating anal acts. This video documents the many degrading anal scenes Mayuko endured at the hands of N, a fellow anal fetishist and sadist.
