Amateur Pickup on the Street targets Itsuki (20), a college student living in Tokyo. Hired by her boyfriend to conduct a cheating investigation, the plan involves picking her up, seducing her, and having sex with her. On the operation day, they meet a cute half-featured gyaru girl with a fun and cheerful personality, successfully convincing her to join. They move to an izakaya, deepening their conversation while she shares erotic stories. She reveals her boyfriend is bad in bed, only lasting one round, leaving her unsatisfied—secretly, she's been enjoying gonzo sex and outdoor sex with other men, making her completely black-hearted. As the lewd investigation progresses, they check into a love hotel, where a handsome guy joins, welcoming her with deep throat action. A never-before-experienced threesome begins. When Itsuki undresses, her beautiful large breasts, slim waist, and peach-shaped ass reveal a stunning erotic body. Dominated by two hot guys, she cums repeatedly with a drooling, blissful expression. A cock-loving girl, she swallows deep into her throat and won't let go. Obsessed with blowjobs, she exposes her defenseless ass, getting doggystyled raw. Her small, tight shaved pussy squeezes tightly, feeling incredibly good. Biting her fingers, her whole body trembles intensely as she fully surrenders to wild, full-throttle sex. Overwhelmed by more pleasure than she ever got from her experienced boyfriend, she drowns in ecstasy. Not satisfied with just once, she eagerly begs for a second creampie. In the end, she requests a facial herself, getting thoroughly splashed with cum to finish. Itsuki closes the scene with a satisfied smile, drenched in sperm.
