Ono and Himori travel for three days to pitch products to regional supermarkets and department stores. Because Himori mistakenly books only one room and every other hotel is full, his strict newlywed boss has no choice but to share a room with him at a hot-spring inn. After she complains about her disappointing married sex life, her teasing, lust-fueled advances blow away his self-control, turning the trip into a raw affair that ends with 20 ejaculations.
