We’ve remade GYM-BOY to make it all new and even better, meet MUSCLE. New name, new additions, same cock squeezin,’ hole pumpin’ action.

MUSCLE is everything you loved about GYM-BOY’s feel and design…but new n’ improved. MUSCLE is made from thicker TPR to give you a fleshier, fatter cock.

Unlike GYM-BOY’s smooth insides, MUSCLE is lined with ridges that massage your meat with each pump n’ stroke.

GYM-BOY may have been one length fits all, but MUSCLE comes with a silicone stopper that locks into the grooves giving you the option of adjusting the fit on your junk.

Now you can get a huge MUSCLE dick with a slurpin’ suction that just don’t quit.

We’re down to our very last batch of GYM-BOY’s…available only in piss clear…so get ‘em before they’re gone. If you missed your shot, don’t worry all you dick-pigs…if you liked GYM-BOY….you’re gonna fuckin’ love our MUSCLE.

Total Length: 8.75 inches
Total Circumference: average 6.5”
Usable Length: 8-9”
Weight: 8.2 oz.

Customer Reviews

Easy to put on, fits well, feels great. Looks awesome!


This is a great extender and was my favourite for a long time, I only prefer the "Daddy cock and balls" now because it's newer and different. My favourite part about this sheath is the base attachment that is identical to the nut sling cockring. Feels great.
Getting this on is really easy with either silicone lube, hybrid lube or even just hand moisturiser. It's not as fat as the daddy cock sheath but still quite long.
Keep this toy away from cheaper PVC toys, they will leave a burn mark on the softer material if stored together (Better yet, just don't have any cheaper PVC toys.)
Oh yeah, looks great when you wear this with the matching zippered latex shorts or gstring.
