21-year-old college student Ririka is here! Petite in stature with a gorgeous F-cup bust, she looks like a soft, fluffy little sister at first glance. But once you talk to her, you'll find she's surprisingly airheaded, full of energy, and prone to accidentally spilling out dirty talk. Standing at just 149cm, she confidently declares, "As long as there's love, appearance and age don't matter!"—a girl truly serious about romance. She's currently enjoying campus life in a department dominated by girls and works part-time at a restaurant, where she gets especially excited whenever scrambled eggs with ham are served as staff meals. Her youth seems to have been spent in artsy clubs like art and light music, and while she hasn't had much romantic experience, her first time was with a friend's boyfriend—something that just sort of happened, and apparently wasn't enjoyable at all, just painful. But since then, she's had plenty of sex and is now fully in a "no sex, no life" mindset. While she doesn't usually watch AVs, she's curious—and today, she nervously signed up after hearing she'd get to do something sexy. At the start of filming, her nervousness is obvious: fidgeting hands, darting eyes, and an adorably shy smile that's irresistibly erotic. When asked to undress, her face turns bright red as she stammers, "Eh, ah, okay..." clearly tense, yet her nipples are already rock hard even before being touched. She's aware of it too, and tries to hide them with her hands—only making it sexier. When asked for a blowjob, she hesitates: "Eh? I might not be good at this..." but then tentatively licks the tip with her tongue, quickly soaking it in saliva and taking it all the way down to the base. Her eroticism is far beyond what you'd expect from a novice. Who says inexperienced girls can't be sexy? Who says lack of technique means it's boring? From this girl who lives by "no sex, no life," what follows is an unbelievably intense, non-stop sex session—completely unlike the tense, stiff girl she was at the beginning.
