Dr. Joel's Stroking Power Pump Endorsed and prescribed by Dr. Joel Kaplan"," this pump features robotic vertical suction action as well as intense multi-speed vibrations. The thick plastic cylinder has a stretchy donut sleeve entrance that is shaped like a mouth and a silicone sleeve that is lined with raised nubs for stimulation during stroking.
