Mina and her husband have been married for almost three years, and they both live in the company's dormitory. Although she has only been married for a few years, because her husband is always busy with work and neglects sex, it makes Mina always feel sexually deprived. On the other hand, Umeda, who lives next door, is her husband's subordinate, and is extremely prolific. Because the walls were so thin, every sound from the house next door was heard by Mina. Umeda and his wife have sex every day, and the wife's moans of pleasure make Mina's desire rise more and more. And when she had exceeded her endurance, she took the opportunity to call the door of Umeda's house as soon as his wife had just left the house. She used her deadly seductive body to enchant him. The sound of their heavy breathing filled the room, they even had sex when Mina's husband was home and let her husband hear her slutty moaning!
