Hina, a cute twin-tailed girl with a younger sister vibe, is walking down the street when she's approached by a strange older man who says, "You're adorable. You're exactly my type." They end up talking in an office, where the man begins lightly touching her. Though Hina gently resists at first, she doesn't push him away strongly, and soon his hands are all over her H-cup breasts, groping them intensely. He then goes down on her, giving fierce cunnilingus to both her anus and pussy, making her react sensitively to the stimulation, clearly overwhelmed with pleasure. Despite her innocent appearance, Hina reveals a deeply naughty side. When told to masturbate, she spreads her pussy wide open with her own hands, her face flushed with arousal as she vigorously rubs her clit with two fingers.
