Nanaho Kase is a married woman, but she still feels lonely because her husband only focuses on work and neglects sex. One day he took his boss and enjoyed Nanaho's cooking. He admired Nanaho's cooking skills so the boss wanted Nanaho to teach him. He took an afternoon off from work to stay at Nanaho's house while her husband went to work. However, he did not focus on cooking but always looked at Nanaho's seductive body to then “swallow” she. The wife after that day always remembered the sexual taste that her husband's boss brought, so she invited him to her house to “learn to cook” many times.
