So you racked your brain to come up with some really sadistic ideas and you came up with some really good ideas. You are going to need these items" mouthwash, lime/lemon juice, glass 2x, several rubberbands, ruler, 2 qtips, and sandpaper (fine grain if you don't want to really hurt yourself). We are going to REALLY push the limits with this. When I am done with you you're going to be in a LOT of pain while I play with you. If you wanted to really step it up, then you're in the right place.
