Oura-san is a married woman who usually works at an IT company, and exudes a refined atmosphere yet a seductive sexiness. When she first got married, she had sex with her husband frequently, but recently the number of times has decreased dramatically, and she feels lonely. As a result of this lifestyle, she could no longer bear her sexual frustration and volunteered to appear in the film in search of pleasure. And when the sexual desire that she had been holding back was suddenly released, her expression as she longingly kissed him and stared at his penis was very impressive.
