A beautiful late-20s office lady from the sales department of E-Mark Co., Ltd. in Chiyoda Ward is featured in this release. Unable to restrain herself on her way home from work, she surrenders to pleasure. This production presents an exclusive, secretly obtained recording of sexual activity taking place within the office—an act considered public in some sense. In a nighttime parking lot, while several employees are still present, a man and woman passionately caress each other behind a car, muffling their moans. The scene begins with mutual oral stimulation, quickly driving the woman to orgasm. As penetration begins, she can no longer suppress her cries, displaying intensely erotic reactions. The action moves inside the office. Taking advantage of the empty building, both strip completely naked and use office chairs and desks to engage in vigorous sex in various positions. Despite knowing coworkers will arrive the next morning, the room becomes soaked in sweat and semen. Oblivious to consequences, the couple continues unprotected sex until dawn.
