An innocent big-breasted gravure idol who has just made her debut is called out in the middle of the night and trained to develop her sexual sensitivity until the morning. She is made to cum in one night! Amidst her anxiety, tension, and embarrassment, she is suddenly thrust hard into her innocent pussy, awakening her to intense pleasure! While restrained, her sensitive nipples are developed with a nipple suction machine, and she is thoroughly trained to clitoris and vaginal orgasms with an electric massager and vibrator. In the end, she begs for a dick, moans obscenely throughout the entire time, her H-cup breasts shaking as she climaxes over and over again!!! Training complete.
