Since childhood, Mayuko (pseudonym) has been obsessed with anal pleasure after secretly watching her elderly aunt defecate outdoors. Throughout elementary, middle, and high school, she repeatedly engaged in anal masturbation alone every day. After graduating from university, she decided to suppress her abnormal anal desires and chose to live as an ordinary woman. She became a teacher, got married, and was blessed with a child. However, her innate anal masochistic tendencies proved impossible to control, and before long, she began secretly performing anal masturbation in her elementary school's restroom. One day, she was discovered by a parent, Mr. N, forcing her to confront her suppressed desires once again. This video realistically depicts Mayuko being tormented in various ways anally by Mr. N, who shares her anal fetish but possesses a sadistic nature. What you are about to see is the actual footage sent directly to the editorial office of an SM magazine, presented here unaltered.
