The latest in the popular series, in which a penis-shaped attachment is attached to a vibrator, inserted and fixed in place, and a timer is used to randomly attack for long periods of time, features the adorable "Ena" with her clear smile and "Yukino" who screams in ecstasy and trembles her slender waist over and over again! As a bonus video, it also includes 'Electric Massager Masturbation (wearing a very thin leotard) right after the Timer Electric Massager Challenge'!!
