The Spike 3 and 5 wheeled Pinwheel from Doc Johnson's Kink collaboration ideal for teasing and tormenting a submissive with unique sensory delights, or as the prologue to a medical fetish play scene. Spike produces a variety of tantalizing sensations and effects depending on the pressure applied; lightly roll the wheel across the skin for a light tickling touch, or press harder to mark or pierce the skin with its sharp prickly points.
