Before we get into the moral implications of sleeping with the friends of your girlfriend, let it be said that this is just for fun.

Friend A: Been in an on-again-off-again relationship with the same guy since she was 16 (early 20's now.) Sometimes hangs out with another guy (unbeknownst to her bf) that wants in her pants, but his game must suck. Doesn't trust her boyfriend at all. Her mom raves about me. Friend A says I have good taste and is shy/laughs in person with me. She is a bit jealous of my girlfriend at times, so I guess I'd be seen as high status because I date her. Known my girl since they were little, but have gotten into brief fights occasionally.

Friend B: Is in a new relationship with a guy she is into because he's a bit of a loser/asshole. I make fun of her and she has sent my girl a pic that has to do with my comments, saying "just for you." Tells me to shut up at times when I tease her. She has similar taste in movies as me (which we've discussed) and has been open to dancing with me at bars (and brought this up to my girl before.) Is very jealous of my girlfriend sometimes.
