Oxballs Muscle Smooth Penis Sheath Length Insert


The Muscle Penis Sheath by Oxballs treats your body to intense pleasure, as it molds to your shape like a second skin.  The gentle ridges add extra intensity with every thrust. This sheath adds instant length which your partner will find exciting!


The Muscle Sheath is a new and improved design by Oxballs. This penis sheath is even more flexible and comfortable than before – with a suction effect that keeps it perfectly in place while you play.  This product 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 grips your testicles for a satisfying tug. It also puts pressure on the base of your penis, keeping you harder for longer. Another feature of this sheath is a small silicone stopper that minimizes the length of the inner chamber, personalizing your toy to suit your size perfectly.  You can use a water-based lubricant on the inside of this sheath if you want extra sensation when you wear it – allowing you to slide gently in and out of your sheath for an incredible sensation.
