Picked up in the streets of Nakano at night is "Sara," a student at a confectionery vocational school. Her helpless expression looking up at me instantly captured my heart. She gives off a gentle, submissive vibe—someone you'd want to protect—yet surprisingly, at just 19 years old, she's had an astonishing 40 partners. How is that possible? I couldn't help but wonder. So I asked her to do some lingerie photography with me. The lingerie features a cute polka-dot design with heart patterns, but with string-style sides adding a slightly sexy touch. It turns out her real erotic charm is even more striking than first impressions suggest—both the lingerie and she herself are unexpectedly naughty. When I gently touched her from behind, she squirmed her hips shyly, making my heart race even more. Lifting her skirt and shifting her panties aside, I could clearly see her little butt hole twitching. Even with just soft touches, she was already wet, and her sexiness drove my excitement through the roof. I couldn't help but press against her through the fabric, and she didn't resist at all—in fact, she enthusiastically responded, clearly enjoying it. Her high partner count definitely shows in her skill. Savoring her soft, juicy 19-year-old breasts, her soaked pussy began dripping thick strings of arousal, flooding out like a tidal wave. When she expertly gave me a blowjob, I couldn't hold back and quickly slid inside. In cowgirl position, she eagerly grinded her hips on her own, and the way she looked up at me with that troubled, pleasured gaze was incredibly seductive—I remember clearly how I ended up cumming deep inside her without pulling out.
