The Oxballs Muscle is a soft, flexible, hollow sheath designed to wear over your penis to add extra length or girth. It can also be used by people with ED conditions.

The Muscle is the original and largest of three different "Muscle" sleeve options from Oxballs. (To see the other sizes, check out the Muscle Ripped and the Muscle Bandit. See the last photo in the array above for a relative size comparison between the three options.)

Made from phthalate-free TPR, the Muscle is soft and flexible... and it stays on. At the base of the sheath it is the Oxballs original COCKSLING 2 design that grips your cock and balls. And the inside of the Muscle has ridges, which add sensation to the wearer during thrusting.

Simply lube up inside the shaft with water-based lube and slide your penis in, then stretch the ball opening and drop your testicles through the hole.

There may be some air space in front of the head of your penis-- just grip the shaft and squeeze out the air, creating vacuum that sucks the sheath down further onto your penis. The Muscle also comes with a small, approximately 1-inch rounded bullet insert to put inside the shaft if you want to shorten the inner chamber a little bit (bullet insert shown in product photos). The first 2.5" at the head of the sheath is solid TPR.

Use water-based lube, as it will be easiest to clean and will help maintain the longevity of the TPR material. Oil-based lubes will deteriorate the material, and silicone lubes will be very difficult to fully clean off of the material. When finished, wash inside and out with soapy warm water and air dry. Store away from direct sunlight.

Please note that TPR is a soft, porous material, and will show wear with use. You cannot fully sanitize TPR, so it is best to use this toy with a condom if you intend to use it with more than one partner.
