This Stretchable cock ring features 70 minutes of long lasting pleasure and stimulation for both partners. The several specially designed small, soft pleasure bumps transfer the stimulating erotic vibrations to the clitoris during sexual intercourse. These cock rings are designed to target the dorsal vein located on the upper side of the penis. When pressure is applied to the dorsal vein it drains blood away from the organ which gives you a stronger and a longer lasting erection.
