In a "boob pub" where men and women can be alone in a dark, narrow private room, the girls sit on the customer's lap and let him rub their breasts. While enjoying the beautiful, firm breasts of Sayumi, the extremely cute and slutty boob pub girl who works at this establishment, he secretly inserts his penis into her without being noticed by the establishment! He even takes her outside the establishment for some raw sex! With the addition of subjective footage, it's even more satisfying!
