The Muscle is the Gym Boy's BIG brother! Muscle is the largest sheath we offer and we dare you to try it.
The inside is ribbed so the wearer feels an intense sucking action as they slide through the ribbing. The receiver just gets a big filling piece of meat! The base is modeled after a cock sling that puts pressure on you shaft and holds this thick rubbery dong on your junk no matter how hard you’re slammin’ in and out.
If you want a tighter fit, no need to worry, each MUSCLE comes with a small silicone stopper that locks perfectly into the grooved indents at whatever length suits your dick. Each sheath has soft TPR ridges that not only feel great gripping your cock, but also adds some cum churning massage sensations all up and down your fuck stick.
