If you’ve ever wished your power wand packed a little more punch, the 8" Muscle Cock Sheath from Oxballs is the upgrade you’ve been craving. This bad boy adds length, girth, and pure visual dominance — transforming your tool into an 8-inch meat log with every thrust. It’s not subtle, it’s not polite — it’s raw, rubbery, and built for blokes who want to bring the noise in the bedroom.

Made from Oxballs’ signature FLEX-TPR, the Muscle Sheath is stretchy and soft enough to slide over your shaft, but thick and heavy enough to give your partner that full-blown “holy shit” stretch with every thrust. The inside is ribbed with a nubby nub that massages your head as you move, while the sheer size of the sleeve puts you in alpha territory the second it goes on.

It includes a firm ball strap at the base that keeps everything locked in tight — so no flopping, no slipping, just deep, controlled power with every stroke. Whether you’re topping hard, playing with size, or just love the visual thrill of looking hung like a stallion, this rig gets it done.

• Soft FLEX-TPR – stretchy, slick, and body-safe for deep play
• Internal nubs – stimulate your head while you thrust
• Realistic shape – thick, blunt, and shaped for maximum impact
