Nagoya is full of attractive women. Hiroshi, a sex toy enthusiast, walks through the city at night driven by an urge to insert vibrators into women all over the world. As dusk falls, something begins stirring inside him. When a beautiful black-haired woman passes by, his "boob radar" instantly reacts. Rather than resisting, he chooses to indulge in the sensation. Clutching his crotch, he heads straight for a hotel. It's only natural that he can't hold back—his underwear transforms. Slipping on ultra-thin panties and a pure white bra that cradles her soft, bountiful breasts, he's completely smitten. Her flawless body is fair, voluptuous, and blessed with large, tender breasts. A cute girl like her deserves a toy treatment. He pulls out the vibrator and buzzes it against her clitoris—VRRRINN. Her nipples stiffen and her breathing turns ragged. This is the ultimate spot—her pleasure builds rapidly. Her body and mind tremble uncontrollably as she moans and climaxes. His sadistic side won't stop. Even if she gives him a pleading, innocent look, he shows no mercy. Harder! Even harder!! Savoring the softness of her breasts, he pushes her to peak ecstasy. She's into intense, dirty pleasure. Together, they unleash an erotic tale on the streets of nighttime Nagoya.
