TV idol Karen Ishida faces one unprecedented sex prank after another. At her home, during a magazine interview, in a café, and even inside a taxi, a naked man with a fully erect cock suddenly bursts in and penetrates her. Confused at first, she soon sucks, fucks, and climaxes repeatedly; before long, she is moving her hips on her own and surrendering completely to the pleasure. With her manager secretly coordinating every location and appointment, the entire schedule becomes one elaborately staged surprise-sex scandal.
