Master Series Locked Cock Locking Cock & Ball Ring Set

The Master Series Locked Cock is a stainless steel cock and ball ring set that locks together with a small gold key. A ball ring sits behind the scrotum, a separate cock ring goes over the shaft, and a locking pin joins the two so the set stays in place until you choose to unlock it. Two ball ring sizes come in the box, and the cool, weighty steel adds a feeling of firmness and control that soft silicone rings don't.

How the lock works

The cock ring slots into the ball ring of your choice, and a gold locking pin pushes through both into a keyhole built into the steel. Turn the key clockwise and pull it out, and the pin stays fixed. To release, put the key back in, turn it counter-clockwise and draw out the key and pin together. There's no padlock dangling from it, just a small, neat mechanism. Keep the key somewhere you can reach easily for the whole session; losing it is the one thing that would turn the fun into a problem.

Choosing your ball ring size

The cock ring has a 1.25-inch inner diameter. For the scrotum, you get two ball rings: 1.75 inches and 2 inches inside. Most people should start with the larger 2-inch ring, since steel has no stretch and a ring that's too small becomes uncomfortable quickly. If it feels loose and slides, try the 1.75-inch one next time. Measure around the base of your penis and scrotum together when soft to get a sense of fit, and compare with our sizing guide before buying other steel rings.

Putting on a locking cock and ball ring

Put it on while soft or semi-flaccid, with a little lube on the skin and the steel. Slip one testicle through the ball ring, then the other, then guide the shaft through. Next, slide the cock ring over the head of the penis and down to meet the ball ring, line it up with the locking pins, and lock it with the key. It takes a few tries to get smooth at this, so practise once without any hurry, ideally in a warm room where your body is relaxed.

For your first sessions, wear it for no more than 30 minutes, and take it off at once if you feel numbness, coldness or pain. Steel can't be cut off as easily as silicone, so build up slowly.

Living with stainless steel

Steel is non-porous and durable, and it works with every type of lube: water-based, silicone or oil. It's temperature sensitive too. Out of the box it feels cool, which some people love; for a warmer start, hold it under warm water for a minute and test it on your wrist. To clean, rinse in warm water with mild soap and spray with toy cleaner, or boil the rings in water for a deeper clean. Dry the lock and pin thoroughly afterwards.
