Shinobu is hurrying down the street to meet a man she has a date with when she slips and falls. She sprains her ankle, trembling in pain, but the man quickly rushes over to her aid. Gently, he pulls out a wet towel to cool her injured foot. As she feels the soothing dampness, he becomes instantly captivated by the sight of her sheer blouse. In that moment, he accidentally spills more water onto her blouse, making it completely transparent and revealing her beautiful, full breasts. Seeing his reaction and her own exposed body, Shinobu begins to realize her own feelings, gradually growing aroused.
