A petite and short girl named "Haruki Uzumi" goes on a 'tobikko' date! She wears a mini-skirt that reveals her cute panties when she climbs up the stairs of a busy building. As soon as she inserts the vibrator inside her panties, it turns on every time she moves, causing her to orgasm quickly. Her sensitive body makes it difficult for her to walk normally while trying to suppress the vibrations. The director teases her by remotely controlling the vibrator, making Haruki feel guilty yet excited at the same time. They find an empty public restroom where they can be alone, but the sound of the motor leaking out from Haruki's panties only adds to their arousal. As she fervently pleasures herself with the vibrator in her mouth, her tight pussy becomes extremely sensitive, making her moan loudly as she experiences multiple orgasms. Throughout the day, Haruki is relentlessly stimulated and made to cum over and over again by the vibrating device hidden in her underwear. By the end of the day, her small frame is covered in sweat and her sensitive pussy is ready to explode at any touch. When a large cock finally penetrates her, she cries out in pleasure as it hits her G-spot, sending waves of ecstasy through her body. Despite being exhausted from all the stimulation, Haruki continues to experience intense orgasms from the rough friction against her swollen clit.
