Since buying a new car, beautiful housewife Riko Miyase had been washing it daily at the front entrance. Her appearance was always stunning, her movements during car washing careful and graceful, captivating anyone who saw her. But recently, her husband began sensing something slightly off. It was because Riko’s bra seemed to be visibly protruding, as if she were deliberately drawing attention to it. Every move she made while washing the car started to feel suspicious, and he grew anxious, constantly wondering whether her bra was showing again. Unconcerned by his worries, neighbors and car wash workers passing by found themselves drawn to Riko’s exposed figure, increasingly fixated on her clearly visible bra lines. Before long, those who noticed her nipples becoming visible through the fabric began devising plans to secretly and thoroughly observe her.
