[Reducing Mosaic]JUL-659 Office sex after a 31-day consecutive work shift and loss of reason. A man and woman pushed to the limit working at a black company. Marika Kobayashi.

Marika, who works at a small advertising agency and is busy every day. In addition, Suzuki, a new graduate who works in the same office as her, spends his days as her company slave. The phone calls never stop ringing, the paperwork piles up, and the hard work that makes it impossible to go home is 31 days in a row. While working overtime at midnight, Suzuki, who has lost his normal judgment, attacks Marika out of hesitation. And Marika, who was on the verge of the limit, was drowning in the pleasure of penetrating her vagina for the first time in a while.
