Waterfall has been married for three years and felt distant from her husband, who was also working. One day, she went on a business trip with her subordinate Akiyama, but due to his mistake, there were only two rooms available at the hotel. Reluctantly agreeing to share a room, they settled down for the night. After getting drunk, Waterfall teased Akiyama, unknowingly arousing him. He proceeded to give her multiple creampies throughout the night until morning.
