Hayami Io, with her G-cup breasts in a white V-neck top, looks incredibly sexy just walking down the street. When approached about becoming a lingerie model, her shy, flustered smile is utterly charming. She mentions that someone once told her, "You're so soft," and "You're really sensitive," but it's been about half a year since she's been touched—when asked if she's been feeling pent-up, her nervous reaction is irresistibly cute. Asked if she can concentrate while her nipples are played with, she's offered a 50,000-yen trial lingerie modeling experience if she can endure mental training. Needing the money beyond her part-time food service job, she changes into pink, sexy lingerie. The moment the pro’s fingers touch her, her whole body jerks involuntarily. Whispering, "This lingerie is so thin, I'm embarrassed," she gradually succumbs to the finger techniques, her wrists eventually bound. Experiencing cotton-swab nipple torture for the first time, she writhes in ecstasy, shocked by her own unimaginable nipple sensitivity. "I'm cumming! I'm cumming!" she cries, tears streaming as she climaxes. With both nipples and her crotch assaulted by triple vibrators, she experiences relentless orgasms—crying, soaking wet, yet unable to stop. After receiving her payment, she promises not to leave from being fucked. When asked if she'll take a bare cock, she looks slightly surprised—but as her nipples are tweaked, she instinctively takes it into her mouth, an insanely erotic sight. She gives a sloppy blowjob, sucking and grinding nipples together, then takes the big cock missionary. Moaning "It's so hard!" she's pounded from behind, hitting nipple, G-spot, and cervix all at once in a triple climax. Screaming that this is the horniest and most desired she's ever felt, she rides at her own pace, slamming down in deep thrusts for a creampie. Hayami Io trembles violently, muscles failing, hyperventilating—but still grinning, completely satisfied.
