This 100% silicone teardrop style cock-ring taps the taint giving you an external prostate massage while constricting your balls and cock. The silicone is firm yet has elasticity and if lockup occurs (penis engorged and yet you can't ejaculate) you can easily sacrifice the silicone instead of calling on paramedics and the ""jaws of life"". Great for using during partner sex. Great for using as a solo toy for masturbation. Made by Tantus the first name in silicone manufacturers. Designed to fit snugly around the shaft and testicles, the C-Sling works much like a classic C-Ring. To use, place a small amount of lubricant on the inside of the sling and slide the sling around the testicles, then the penis. Its contoured tongue should point down and back toward the anus, to gently massage the perineum.
