In Tokyo's Shinjuku Ward, at a renowned department store known by all, we find four beautiful saleswomen working in the cosmetics department on the first floor, a place where the store's most attractive employees gather. These elegant and refined women, always aware of being watched, diligently perform their duties. During their break, they are ambushed and taken to the back room for a brutal assault. These beautiful women are forcibly defiled, their pristine bodies violated as they are filled with a man's semen, like a reservoir overflowing.
