Massive Public Display of Affection

So, wait. Let me get this straight. That's your - creepy - girlfriend over there glaring at us. She's furious at you because you've been staring at me and my big boobies, and they are very big, and yes you have been staring, cutie. And I noticed you filming me too, you naughty boy....

So now you want to give her something to be really mad about. Hmmmm, OK! I’m in. What do you have in mind?
