A mundane life with her husband, and fleeting nights of intimacy. Aki guides her own fingers between her thighs, as a whisper from another self murmurs in her ear: "You don't want to grow old like this, do you?" Those words stir unbearable weariness and desperation, spiraling into infinite lust. Suddenly, a visitor appears, groping her full breasts and thrusting into her core. The moment her chastity shatters, Aki drowns in maddening pleasure, shedding her dignity as a married woman and transforming into a drifting wanderer of desire.
