Here’s the problem, your butt plug has slipped loose.  Guess its time for a bigger one.  We will take care of that for you in the locker room later.  For now, just clench down for the rest of the game.  

I can help you out by pulling the straps of your jock over and using them to hold the plug in your gaping, cum filled, jock hole.  Don’t want all those cum loads leaking out here in front of everyone, do you?
