Big-breasted beauty Sezaki Ayane makes her debut with Fitch, drawing attention as she takes on her first-ever encounter with a black man. Busy with work, both husband and wife rarely get time together, so they head to a ryokan reserved by her husband for a long-overdue romantic getaway. However, the inn turns out to be a cheap lodging, and they discover a black man staying right on the other side of the thin sliding door. Enraged by the situation, the husband storms out and abandons her. Left alone, Ayane finds herself spending time with the black man, and an unexpected emotional connection begins to grow between them, deepening into an intense physical relationship.
