HULK cocksheath is huge. It is the biggest cocksheath ever...it makes what you have HUGEST! This thing is a massive heavy meaty slab of dick for the really hulky holes. Made of thick rubbery flexTPR, this wraps around your meat adding 3-5 X more girth and 5-7 inches more length...it's really big. HULK stays on your hard or soft dick with our cocksling base but as you stroke (our cocksheaths make amazing JO strokers), this one has heavy inner ridges and nubs that jack you while you tug it, or fuck with it...this thing isn't just for others' pleasure while you pump and hump—it gives you a lot of sucking tug on your knob. Made of our stretchy flexTPR, it's rubbery but firm enough to play fast and hard, stretchy enough to fit on you and it sucks onto you pulling you in while you play. HERE's HOW: lube your junk just a bit, slide in squeezing the shaft hole air out so it sucks you in...once all the way in, stretch the ball hole and drop your bag through. Comes with our ADJUSTfit soft rubbery bullet insert so you can custom fit to your shaft size...get additional ADJUSTfit inserts in three-packs for even more custom fit—we design to fit any size shaft.
