A fair-skinned, big-titted beauty named Ritsuko, with small salmon-pink nipples and plump areolas. Wearing a sailor uniform, she appears well-behaved and innocent at first glance, but hides an incredibly horny side. During her school days, she had around 30 sexual partners, revealing her surprisingly active and adventurous sex life. She lost her virginity in her second year of high school to an upperclassman she wasn't particularly fond of, just for fun—and surprisingly, she enjoyed it from the very beginning. This supports the common theory that girls who enjoy sex right away usually have a history of masturbation. In fact, she's been pleasuring herself since upper elementary school, rubbing against walls and floors while fantasizing. Now, her number of partners is countless—she's fully aware of her strong libido and proudly embraces her identity as a promiscuous, sex-loving girl. She masturbates 4 to 5 times a week and still enjoys floor masturbation, often trembling her ass in excitement. Experience creampie sex with her on a high-risk day.
