Yuki Kojima meets up at a busy park and learns that she will be wearing a remote-controlled vibrator inside her panties. After slipping it in behind a sheltered bench, she gasps as the vibrations begin, then walks around with the toy still running. Different settings torment her on the swings and stairs while she nervously passes close to other people, afraid they will hear it. The public thrill makes her increasingly sensitive, and the outing ends with her heated, toy-stimulated pussy getting fucked and creampied.
