Mayuko (pseudonym) has been drawn to anal pleasure since childhood, spending her elementary, middle, and high school years repeatedly engaging in solo anal masturbation. After graduating from university, she realized "this can't go on," deciding to suppress her anal desires and live as an ordinary woman. She chose a career as a female teacher, got married, and gave birth to a daughter. However, her innate, abnormal anal masochistic tendencies proved impossible to control, and before long, she began secretly performing anal masturbation in the restrooms at her workplace, an elementary school. Her acts were accidentally discovered by male parent N, a fellow sadist, triggering a shocking turn of events. This video documents Mayuko being tormented anally by N, climaxing repeatedly through extreme, fetishistic acts. Content includes shower enemas, self-fisting, painful anal floggings, and a threesome involving her student. This is an amateur BDSM recording shot entirely by real-life practitioners, with no scripted acting, production, or narrative—just raw, explicit footage capturing authentic, depraved play.
