Maria Wakatuki, a shy, black-haired college girl who just debuted at a women's university. With experience of only two men, this pure junior dealer made a wrong choice somewhere—entering into a mistress contract with an older man. Perhaps due to the anxiety and loneliness of living alone, she's now being trained as a sexually obedient girl who can be summoned anytime. Using mature, lingering sexual techniques, she's being guided into prolonged pleasure, with each erogenous zone of her body gradually awakened one by one. Afterward, they review the gonzo footage together, analyzing her performance and molding her into a greedy, persistent female dog. From Sledgehammer, a label under Shark, comes "Amateur Girls’ Private Filming Fuck Diary"—a raw, amateur gonzo blowjob and training session featuring a female college student.
