if you were alone in the room with some chick about to suck your dick, and she was your best friends girl, it's too sticky (no pun intended) of a situation, and 9/10 of you would get head. Maybe one of you would really realize it, but i can guarantee you right now almost all of you would accept. Now, you may say you wouldn't, but thats just now. I'd take her back, (she was drunk, come on) but i'd make her convince me why i should take her back, and how would i be positive she would never pull that shit again. If you're more the insensitive type, give that ho the back of your hand.
