The unique feature of the Rolling Head Cup is the ability to simultaneously massage the tip of your member with the rolling motion while doing the piston motion with the rest of the tube. This sensation is created by the small rubber ball at the tip of the cup that provides an additional resistance while the flexible tube body offers a range of stimuli motion to the penis shaft. The flexible folds at the mid section of the Rolling Head Cup allows a range of powerful stimulations: up, rolling, up, quick, down, slow, pulling, left, back, right, forth, or just simple circular motion while holding on to the top of the tube.
