Experience incredible shared stimulation by slipping the Fifty Shades of Grey Feel It Vibrating Cock Ring over his manhood before intercourse. The stretchy silicone ring is designed to sit around the base of the penis. Brilliantly versatile, the single speed bullet vibe can be used inside the ring to stimulate the clitoris or testicles during intercourse, or slipped out of the cock ring. Use the ring as a non-vibrating toy if you prefer to help maintain erections.
