Wipping the Grin Off His Face

A waiting cell was just that, and there were strict rules that the prisoners had to be left alone.  But what the rules said and what actually happened was, well, kind of different.  This guy was still giving lip, despite the clamps.  We'd have to fix that.  The sheriff reached into his drawer.  Where is it?  Ah, here it is.  A large powerful bulldog clip.  It had corrected so many guys' balls.  They were all street brawlers and thought they could take anything.  Until their balls said hello to the sheriff's bulldog clip.  A couple of hours of that and they were corrected.  Punished.  Disciplined.  He'd jack them till they were there, then as they climaxed he'd take it off.  Shooting your muck in pure agony.  Just one of the tricks you learned in the waiting cell
