At 8 p.m., a company drinking party leaves Nami Togawa, a coworker from the same department, heavily intoxicated. While he is driving her home, she excitedly pressures him into stopping at a hotel. As he looks after her, she kisses him first and the situation turns into sex. She falls asleep afterward and later sobers up enough to apologize for what happened. But she cannot forget how good the sex felt and asks to do it again. She lies to her husband over the phone, decides to stay the night, and loses herself in repeated sex until morning, swallowing cum and taking creampies along the way.
