The whole story of a married woman who is attracted to a part-time college student instructor she meets at the cram school where her son attends and has an affair. A younger man suddenly confesses his love to her and tries to kiss her, but as a married mother, she refuses rationally... but the man forces her and she falls. Her breasts are massaged violently, her protruding nipples are played with, and her crotch is touched. "Hey! Don't lick there!" Her private parts are sucked violently with a tongue and she writhes in agony! Her head is held down and an erect penis is forced into her mouth. She is on all fours and penetrated from behind, causing her to become aroused. "Ah... Don't do that so violently! I'm cumming!" "Did you cum (inside) me?..." From that day on, the married woman continues to visit the young man's house frequently and has multiple affairs. They take off their clothes at the entrance and take the penis in their mouths! They lick each other's genitals, "Put it in from behind like this... Ah it feels good... Ah~ It's hard and feels good! I like that!" She offers her body to his desires without considering her family.
