Rika is a well-mannered and popular female student at her school. She's an innocent girl who becomes involved in sexual activities after being persuaded by a friend to engage in a casual relationship with him. One day, she unknowingly consumes aphrodisiac that makes her extremely horny and sensitive to touch. The sex addictions take over her body as she begs for more, eventually leading to anal sex and creampies. As the video progresses, we see various positions including cowgirl, doggystyle, missionary, and even some bondage elements like strangulation during intercourse. Throughout the entire experience, Rika transforms from a shy virgin into a willing slut who enjoys every moment of their passionate encounters.
