Haruna, 28 years old. Height 162cm, weight 48kg. Bust 88cm (D cup), waist 59cm, hips 85cm. Blood type O. At 19, attending an all-girls high school where erotic talk was common, she stayed true to herself and after graduation moved to Tokyo, where she had her first sexual experience in a guy's room. Her initiation into masturbation came when he told her, "Do it like this, just stimulate it a little," and she thought, "Ah, I see," gradually becoming aware of pleasure. With a slightly masochistic side, she's tied to a punishment chair, and as two brushes crawl across her body, she wonders, "What's this?" with curiosity, but quickly responds with, "I'm getting wet," and "That feels amazing," openly embracing the pleasure. Transitioning from feather-light brush strokes to a vibrator, she moans, "It feels even better than before," gasping and writhing under teasing stimulation. When the vibration reaches her sensitive clit, she cries, "Hii—more, it's getting so hot," as a wet spot spreads on her white panties. Two fingers slide into her heated pussy, making her moan lewdly, "It feels good, so good," her inner thighs trembling in spasms. She also reveals her lustful side, craving more. Stimulated simultaneously by two fingers inside and another rubbing her clit, she screams, "I'm cumming, I'm cumming, Aaaah—Kuu," whimpering like a sob, her breath ragged with ecstasy, reaching climax. Applying the vibrator directly to her clit, she pleads, "Aa, Kuu, Kuu, no more," clearly overwhelmed, panting like after an all-out sprint. Her masturbation is filmed from two angles using fixed cameras, one frontal and one from the side. She gets turned on by using ice to stimulate her nipples and clit, and by wearing a blindfold. She enjoys blindfolding because it lets her expose herself completely—she feels embarrassed when she can see. "It hides my shyness and lets my instincts come out," she says. She announces, "I'll prepare the ice, eye mask, and brush," revealing she often uses ice on her nipples and clit and sometimes blindfolds herself. According to her, not seeing helps her concentrate and fantasize, increasing arousal, so she puts on the blindfold herself. First, she stimulates her nipples with the brush, then touches them with ice-coated fingers, and brushes the handle against her groin. With the blindfold on, she fumbles to grab ice, tracing from her neck down to her nipples, using the brush as well, indulging in self-play that mimics being touched by someone else, hitting all her pleasure spots. As pleasure builds, she rubs her clit at super speed, rapidly touching her nipples too, approaching orgasm while her pantyhose and panties remain tangled at her ankles. "Aa, no, stop, I'm cumming, no, it's too good, too good, there, there, right there," she frantically grinds her clit like it's vibrating uncontrollably. Her legs jerk awkwardly as she peaks, visibly trembling in ecstasy. Still caught in the aftershocks, breathing heavily, she gets dressed without removing her panties and pantyhose or wiping her groin, the raw moment clearly visible. She's also seen urinating on the tatami floor. She squats and pees noisily into a red fire extinguisher bucket in front of the camera, wipes with tissue, picks up the bucket, and heads to the toilet, where she flushes a small amount of slightly yellow urine.
