We all decided to have a drinking party at the part-time job. It's not really a drinking party, but we, who work at a bookstore in the cultural industry, are just having a light drink and going home before the last train. That's how it used to be... This time, Ikura Uno, a new part-time worker, participated for the first time. The glasses girl, who is quiet, serious, and highly regarded by her employees, was drinking heavily as if she was nervous, and somehow she was already drunk. When everyone at the part-time job had left, I thought I would take care of my drunk junior, but I became curious about her big ass and was staring at it when she asked me for anal sex! I was surprised by the sudden change, but I graduated her from anal virginity out of a sense of responsibility. Long-awaited anal orgasm with anal insertion, where only fantasies had been swelling! I set her quiet libido on fire and creampied her ass all night long!
