The latest installment in the popular series that involves inserting and fixing a penis-shaped attachment to an electric massager, and relentlessly attacking with a timer for extended periods, features a beautiful mature woman who climaxes repeatedly from the first activation! Yuuka-san, a slender Okinawan beauty who looks elegant on the bed, reaches climax after climax, her consciousness blurring! This is Ran-san. As a bonus video, we also have a scene of her masturbating with the electric massager right after the Timer Electric Massager Challenge, wearing a super-thin leotard!
