Miho Aragaki is a fourth-year student at a prestigious university, standing 165cm tall with stunning beauty and a well-endowed figure. Born into an affluent family—her father is an executive at a major trading company—she was raised in an American school environment, growing up as a proper young lady completely unaware of the dangers of the real world. She falls prey to a skilled pickup artist who seduces her into a hotel. Initially shy and flustered by his vulgar words, her body gradually grows increasingly responsive. Having been without a boyfriend for some time, she realizes her body has become especially sensitive. When he lightly touches her big tits, she flails cutely in reaction, delighting him and driving him to intensify his foreplay. Miho soon loses herself in the sensation, surrendering completely to his relentless teasing. Overcome by long-forgotten pleasure, her body trembles as she orgasms again and again.
