Grundle Knuckle is when the taint is rubbed or massaged to cause a dude to cum
Bruce was getting an old fashioned HJ and Stacy wanted to speed things up and gave him the old Grundle Knuckle to help him cum more.
When hitting a large jump (booter) mainly on skis there is a roller or knuckle that the jump sits on. If you hit that jump and land a little short that is called a case. But if you case the jump so hard that you are ejected from your skis and you thrust your body so hard against the landing that is called a Knuckle Fuck because you are fucking the knuckle.
Dude, that guy hit the pro jump line and knuckle fucked the last jump.
Getting fucked while your balls are vibrating from the wavelengths of Knuckle Puck’s live performance.
Ugh, I can’t wait to get Knuckle Fucked in Orlando in 2 weeks!
