EKDV-638 During a rough patch with my brother, I was tempted from the morning by my sister-in-law, Mai-san, and ended up getting carried away with her many times… Kamisaki Mai

Three years into her marriage to her older brother, Mai’s relationship with her husband has grown colder over time, no matter how beautiful she is. One morning, after a minor argument with her husband, Mai reaches her limit from everyday stress and, with nowhere else to go, heads to her husband’s younger brother’s house. After entering the room, Mai feels the limits of her pent-up desires and, before she knows it, slips under her brother-in-law’s sheets and begins to tempt him. She pours all the frustration built up during her stagnant married life onto him, leading to an intense and passionate encounter. Even though she knows it is wrong, her seductive advances and guilt toward her husband do not stop, and from morning onward they remain tangled together under the sheets, repeatedly giving in to desire.
