A pair of notorious delinquents who are always thinking about lewd things. One day, they were scolded by 'ayumi,' the mother of a classmate, for littering and public waste disposal. Seeing her large breasts and panty flash, they became lustful and hatched a wicked plan. As it turns out, ayumi was sexually frustrated, overwhelmed by her ripe body, and was having an affair with their homeroom teacher. Unwittingly, she was caught in the act by the delinquents. Using this as leverage, they blackmailed her into having sex. Reluctantly, she gave in, but was overwhelmed by the robust, erect penis thrusting deeply inside her, reaching orgasm and being filled with semen. Tied up with jump ropes and yo-yos, tormented with toys, and even brought to climax by her own son's penis, this married woman with large breasts fell into the hands of the delinquents.
