['Work in just your underwear' - is this work, or...] Mayu (25), a new office lady, is forced to strip down to her underwear because she can't do her job. The atmosphere in the office becomes strangely distorted, and everyone starts treating her as a "sexual service officer." Under the desk, in the conference room, in front of the copy machine... the men's desires reach their limits as they watch the busty office lady wander around in just her lingerie.

In the name of 'take responsibility', she is given one immoral order after another. Wet with shame and pleasure, she succumbs without being able to resist... The lewd behind-the-scenes work that takes place in the workplace of an underwear manufacturer - the whole story.
