At a cafe in front of Shinagawa Station, we met Koharu, a pure-looking black-haired beauty. She's tall and slender with stunning legs, her figure accentuated by the dress she's wearing. She hasn't had a boyfriend in about two years and hasn't had sex either. She uses toys for masturbation about twice a week, but still feels unsatisfied—her libido is constantly high, always leaving her aroused. Let's watch Koharu's live masturbation session. By chance, we had a vibrator on hand, which we handed to her. Shyly, she turns it on. "Mmm... too strong... it feels sooo good..." She trembles as her sensitivity steadily increases. Her breathing grows heavier. We have her stand in her lingerie and press the vibrator against her again. "Ahh! Aaah!!" She shudders with strong reactions. Her nipples are erect, and when we suck them with a *slurping* sound, her sensitivity spikes even more. A wet spot appears on her panties. We put her on all fours and apply the vibrator from behind. Around the 25-minute mark, she moans, "Auuu!! I'm cumming! I'm gonna cum!!" clearly overwhelmed with pleasure. She tries to stifle her moans by covering her mouth—such a turn-on. "Aaah... my pussy... it's all stringy... twitching so much..." She looks incredibly turned on. When we go down on her, she squeals, "No! Aaah!" with an adorably sensitive reaction. Inserting a finger into her tight pussy makes her scream, "Aaah! Nooo!" as fluids gush out. Unable to hold back, she starts craving cock. She eagerly takes it deep into her mouth, saying, "So delicious," sucking all the way to the base. Her mouth is slick and warm, incredibly pleasurable. It's intense—I'm about to cum. Pushing my erect cock into her tight, shaved pussy, she gasps, "So amazing... I can't stop moaning." The tight grip feels amazing. Gripping her arms, I thrust into her hard and fast. "No! No!" she cries, feeling as if she's about to ascend to heaven. We switch to cowgirl position, and Koharu starts bouncing on her own. Around the 40-minute mark, the close-up of her pussy is extremely erotic. Riding while pressing the vibrator against herself, she jerks up with each pulse of pleasure. Koharu cums again. The doggy style at around 52 minutes, with her clinging to the pillow, is absolutely perfect. Never before have I met a girl so intensely passionate and sensitive. Koharu keeps trembling and convulsing until the very end—absolutely adorable.
