Eight years into a loveless marriage, Nami is approached on the street by a man she barely recognizes. He is Odagiri, the childhood friend who had a crush on her twenty years earlier, now grown into a handsome, muscular adult. While her husband is away, Odagiri arrives soaked by the rain, and Nami lets him use her shower. She accidentally sees his huge cock, nothing like what she remembers from childhood. Overcome with lust, she loses control and gives herself to condomless sex with him again and again.
