AV director Kyosuke Murayama went on a private shooting trip with an acquaintance's married woman. Since it was a day trip, the married woman, who had no children, joined casually... Ame (pseudonym), 35 years old, married for 10 years. "Mr. Murayama, my husband trusts me, so... go ahead," said the married woman, who had been in contact with Director Murayama through theater-related activities before marriage and had withdrawn from theater after marriage. Due to a certain opportunity, the married woman, who felt cramped in her daily life due to a rift in her relationship with her husband, was invited by Director Murayama to a hot spring. Reluctantly agreeing to a mixed bath, the married woman was teased with her large breasts and female genitalia, writhing in pleasure. "Iiiii! This is the first time! I'm coming! I'm coming!" The married woman, who had an affair with a male acquaintance in secret from her husband, experienced an orgasm for the first time in her life.
