A 20-year-old freeter named Anzu, the kind of naturally airheaded girl you'd see on the streets of Osaka. She's into fashion and looks just like an ordinary college student, but the moment she steps into a hotel, she undergoes an instant transformation. Contrasting her usual innocent demeanor, she reveals a hidden, deeply horny side. She eagerly takes the cock into her mouth herself, sucking it until it erupts—her behavior almost like a completely different person. Going wild with the vibrator, she moans loudly during penetration, exposing her true nature in an instant. By the end, she still feels unsatisfied and even starts begging for more. This is a title that lets you fully enjoy the secret, opposite side of her everyday self.
