NUBBER is designed to achieve a full release by rubbing your prostate nub. The head on the plug end is about the size of a cherry tomato. The “nipple” on the tip gives that little extra tingle. The shaft is only a little thinner than a hot-dog, so this one is great for tight-holed tops who want their nub rubbed while they fuck or jack.
When you stroke, the motion is transmitted from the cock-ring to the plug. So kick back and enjoy your eyes rolling back into your head.
