Ayumi Nakagawa, with her large breasts and slender waist, has a 'jump-strap' device attached inside her panties! While walking through busy streets or in family restaurants, Ayumi is teased by a man who remotely controls the 'jump-strap,' causing her to writhe and stagger like a drunken duck. Moving to the stairs of an office building, once out of sight, she immediately spreads her legs in an M-shape and fully enjoys the stimulation from the 'jump-strap.' Angered by the man who switches it on in public places for his amusement, Ayumi is appeased with a sweet parfait during a break, but she's teased again, forcing her to squirm discreetly. Unable to hold back, she lovingly performs fellatio on an erect penis on the building's outdoor stairs and receives oral ejaculation. Even after moving to a hotel, Ayumi complains, 'It's not fair that only he gets to cum...' Leaning against the sofa while receiving cunnilingus, she experiences a different kind of warm pleasure, moaning with ecstasy! Throughout their date, her vagina, constantly stimulated by the 'jump-strap,' is swollen and engorged. Taking responsibility for arousing her, Ayumi demands a 'second round' in sexy lingerie. Prepared as a 'new toy,' another man licks her breasts, making her face melt with pleasure. Her 'excited and swollen clitoris' is exposed through the gap in her crotchless panties, allowing penetration. Ayumi shakes her breasts as they engage in intense, mutual sex! Losing all inhibitions, Ayumi's face flushes red as she reaches orgasm, then performs fellatio on the ejaculating penis, showing a satisfied smile.
