Drunk and grinning, the new big-titted office lady and her boss go wild in a mistaken shared hotel room, fucking nonstop until right before work - Misono Mizuhara
New office lady Mizho (Misono Mizuhara) makes a mistake at work and gets scolded harshly by a senior colleague. At that moment, Director Shimo-kawa kindly encourages her, treating her with warmth and care. However, Shimo-kawa is not just a kind superior—he's actually a pervert who loves big tits and the sweaty scent of pantyhose, and he has his sights set on Mizho. One day, male coworkers organize a welcome party for her during a business trip. Mizho, cheerful and fond of alcohol, keeps drinking whatever is poured for her until she becomes completely drunk. Seeing her in this state, Shimo-kawa feels this is the long-awaited opportunity and moves in closer to her.
