A cold marital relationship. The wife, Aika, was growing lonelier by the day. With no intimate nights with her husband, her skin and excess fat were loosening up as she aged. She secretly bought corrective underwear... One day, she was seen in her underwear by her husband's younger brother. The brother-in-law couldn't contain his excitement at the sight of his sister-in-law's lewd appearance. Knowing that their relationship was forbidden, they still indulged in taboo acts and escalated further.
