The 6-Pack Cock Ring is built for rough hard-muscled sex, hard crunch, power lifting, grunting, hit the wall, spike it in the end-zone sex. It's light weight-tight enough to keep your fuck-muscle hard, but super stretchy to keep your nuts in play. Made by ATOMIC JOCK, using SkinFlex blend, a resilient non-toxic super plastic that stretches 8X it's original size and snaps back into shape every time.
