Right now every guy in this stadium is watching me lay on top of you.  Those in front can probably see my ass moving up and down slightly as I rub my ten inch cock against your ass crack.  The longer we lay here the more obvious it becomes.  When I stand up and the men see my boner tenting the front of my shorts they will know for sure what is happening.

But when you stand up and show them your hard on, as you pull your shorts out of your ass crack, they will know for sure, you liked it.
