Mizuki, a sweet-faced, pure-looking lolita, is dragged into a creepy guy's room while still wearing her school uniform and treated as his personal flesh hole. Subjected daily to lewd acts she's never experienced before, her true masochistic nature gradually awakens. As the man's filthy hands roam all over her body, her expression slowly transforms, twitching and reacting involuntarily, revealing an increasingly depraved look. With the torment escalating further, her loss of control intensifies—she's made to squirt repeatedly through relentless vibrator and hand job sessions, climaxing over and over in a continuous frenzy.
