43-year-old Haruna Aihara, after losing her husband last year, rediscovers her youthful fascination with lesbianism and meets Reiko Nakajima online. Reiko Nakajima, 51, has walked the lesbian path since childhood, when a woman in a red under-kimono first introduced her to lesbian pleasure. She has never married, living alone and devoted to this lifestyle. The two quickly bond online and arrange to meet at Reiko's home. Entwining their bodies, they spend a long, passionate lesbian night together, both draped in red under-kimonos.
