20-year-old female college student Mai has a slender, pale, and glossy body, harboring a secret desire to have her untouched anus penetrated. To experience her first anal intercourse, she agreed to be filmed undergoing training to develop her virgin anus. This video captures her transformation as she endures the pain and pleasure of anal stretching, learns submission through mind and body, and evolves into a depraved woman who repeatedly climaxes from anal sex. Her agonized expressions from pain and ecstasy during anal orgasms are meticulously recorded, making this an irresistible title for fans of extreme anal training. *This work is a re-edited version of "I've Been Saving My First Asshole for Someone to Take. Mai Miura" (Item No: 2cwm00162).
