The couple's relationship was good, but Yurika's husband became too busy with work and developed ED. At that time, her brother-in-law came to stay at their home for about a week while studying to obtain a license as a judo therapist. One night, Yurika brought him a late-night snack and offered to be his massage practice partner. Seduced by his skilled hands, she was overwhelmed by uncontrollable desire. After experiencing a full massage, Yurika grew increasingly aroused, and her brother-in-law could no longer restrain himself, passionately taking her. Their bond deepened over time, growing stronger with each encounter. However, their affair came to an abrupt end when the brother-in-law returned home. Later, Yurika discovered she was pregnant, and her husband left the family. What became of Yurika and her child afterward remains unknown to everyone.
