Kana Yume, a Japanese schoolgirl with a uniform as pristine as her innocence, finds herself in a compromising position with the much older Toru Ozawa. He takes advantage of her naivety, leading her through a series of firsts - her first deepthroat, her first taste of ass, her first time getting fucked hard. Despite her sweet demeanor, she's a eager learner, moaning and writhing as Ozawa pushes her boundaries, leaving her breathless and spent.
