Hasumi, the new office employee drawing attention, is popular in the company thanks to her gentle personality and approachable baby face. Standing 170cm tall, her long, beautiful legs peeking out from under her skirt are a major charm, not to mention the alluring body hidden beneath her uniform. One day, Hasumi notices someone entering the restroom. Drip drip drip... hearing that sound, what's going on? Viiib Viiib Viiib... Huh?! "Haah... haah... ahh!!!" Hasumi gasps in shock. Doing something like this in the office—there's no going back now. Everyone can't help but be drawn in, eager to see how she'll react.
