15-year-old Rena has had her first experience, with around five partners so far... though she speaks vaguely, suggesting the real number might be higher. Among her past relationships, the shortest lasted just one week. Even though she claims to have fallen in love, she somehow cooled down quickly, making her seem like she gets bored easily—but surprisingly, she also had a relationship that lasted three whole years. Her demeanor and aura give off a mature vibe, making her personality hard to read. As Rena talks, it becomes clear she's actually quite bold. She describes her past experiences as "normal sex," but the details hint at something far more erotic. For instance, when someone mentions "the beach," you might imagine playful fun with inflatable rings, floating and cuddling—that kind of thing. That'd be pretty hot. But Rena has actually had sex right on the roadside. On the road...!? Not even hidden behind bushes or anything—literally out in the open. You could brush it off as youthful recklessness, but she's still very young, so how young was she when she did it? There are girls who get turned on by outdoor sex, and Rena seems like a textbook example. She doesn't think of herself as sexy at all, but the fact she can actually do it outside makes her unexpectedly erotic. Her shy, blushing smile is incredibly cute—yet here she is, calling herself a pure girl while having sex outdoors. Isn't that kind of cheating? It's so hot it makes you lose control and reach your limit!
