[Big Poppa Smurf]

Bump for dramabomb and this important question: Let's say this girl likes you a lot and you don't like her, and after some mishaps you sort it all out. How do you proceed to have sex with her best friend? Assume this friend is interested but likes to pull the "oh you think I'm a [censored], oh I can't hook up with you since she's my best friend" stuff. I can handle the first, but I need a good way to overcome that whole "my friend loves you" thing.
