C-rings are a blast for long JO play--pulling your balls or tugging your sack can really make stroking feel amazing, CONNECT is a c-ring that does the tugging for you.
CONNECT is a c-ring with an attached ball-ring--the cockring is super rubbery and can be worn for long play and the ball-ring is the right size to tug most any size sack without digging into you. The 2 rings are attached with a wide connector that acts like a rubbery flexing spring, it's strong enough for plenty of pull, but stretchy enough for a lot of tug.
Wear CONNECT for play or for a bigger, ballsier bulge.
Hünkyjunk makes toys that work--there are many c-ring/ball-ring combos but none connect the way ours does with rings designed to fit and feel right with a really good tug!
