Self-proclaimed "lover of married women" AV director Takashi Takahashi invites his wife's friend to stay at his house with ulterior motives. Alone for a night, nothing happens to the married woman... Terumi, 36, married for 9 years, works at a cram school. While talking about married life, the director asks the married woman if her husband has NTR attributes. As practice for testing her husband, they mutually touch each other's bodies... She reacts sensitively because it's been a while, her face melts, she secretes a large amount of love juice, and she moans repeatedly, saying "It's big" as the penis is inserted. At night, she is made to cum with toys, and in the morning, she acts like a spoiled child, wanting to have sex, sucking the penis to the root, and opening her mouth wide as her vagina is penetrated. She whispers to her partner, "Cum... Feel good" and finishes.
