Twenty-year-old college student and gravure idol TOUNO KARIN normally masturbates all the time, but she is ordered to abstain from both sex and masturbation for a full month. Teased with acts such as sucking a dildo, she grows so desperate that her panties are already soaked before filming begins. When a real cock finally appears, she eagerly gives it a deep, sloppy blowjob and instinctively bucks her hips for penetration. The moment it enters, overwhelming pleasure sends her into full-body convulsions. Relentless thrusts make her come again and again until her legs give out and she gushes fluids and squirts everywhere in the most intense sexual experience of her life.
