I confess that, although I'm happily married, I can't stop thinking about one of my wife's girl friends. She's petite, and likes to dress provocatively in the summer. She has a boyfriend, however, and is absolutely awful at managing her finances; she's happy to blow her (and her friends') pay checks on a new phone or a shopping spree. I think she craves attention, as she doesn't have many friends who can stand to hang out with her for as long as she wants to (every day, pretty much).
I want to have her, but she's my wife's friend and I'm worried that she'll tell her if I try anything.
