Not one but two powerful vibrating stimulators. Simply wear at the base of the penis with the larger clitoral stimulator on the top, operated by a simple push button control on the side. Let the smaller bubble type vibrator hang below, again push button controlled, and in sexual positions like the doggy style, you will find that it swings against the clitoral area with each thrust that you make. By turning on both vibrating sections, you will have stimulation along the shaft of the penis, around the testicle area and also clitoral stimulation for your partner.- Waterproof- ABS/Silicone (Phthalate Free) Material- Includes 3 x LR44 and 2 x LR1130 batteries
