23-year-old perverted gyaru girl Mone Mashiro has grown unsatisfied with ordinary masturbation. She's become addicted to the twisted fetish of public masturbation, chasing sensations she can't achieve alone at home. The thrill of being in public spaces sends her into an exhilarating high, making her nipples erect and twitch intensely. Overcome by the stimulation, she loses all awareness of her surroundings, completely losing herself as she cums again and again.
