More Info

The Oxballs Muscle cock sheath is a new and improved version of the popular Oxballs Gym-Boy. This penis sheath is even more flexible and comfortable than before, and it moulds to your body like a second skin with a suction effect that keeps it perfectly in place while you play. This cock sheath adds instant length to your penis for an impressive size that your partner will love. This penis sheath doesn’t only add visual impact to your play, it also stimulates you with extra sensation thanks to the soft TPR ridges that massage you with every stroke and thrust. The base of this penis sheath is modelled on the Cocksling-2, and grips your testicles for a satisfying tug. It also puts pressure on the base of your penis, keeping you harder for longer. This sheath comes with a small silicone stopper that minimises the length of the inner chamber, personalising your toy to suit your size perfectly. This sheath can be used with a water based lubricant - if you want extra sensation when you wear it, simply add lubricant to the inside too, allowing you to slide gently in and out of your sheath for incredible sensation. This toy measures 9.25 inches in length and flexes to fit your size for maximum comfort. It’s phthalate free, non-toxic and easily cleaned for low level maintenance.
