A popular reader model known as a "cool older sister." Fans adore her as an older sister, but she is submissive in front of men. She seems to have a desire to be messed around with, and her glamorous body exudes a sexy aura! 2nd person: Hina(18), a current first-year university student. Although she is small, she is a talented sports girl who was active as a setter in the volleyball club. When an adult man pushes her around, Kokoro gets the better of her... Her immature body, which is on the verge of becoming an adult woman, is extremely erotic, and her whole body is tense, trembling and convulsing as she orgasms over and over again. It's a spectacular sight.
