I used to work with a Lesbian lady who's "partner" was also not the hottest thing on the planet, but neither of them would shrivel up most men's cocks too badly...
Anyway, they both are intollerable to be around when not at work. I swear it is like they get off on grossing out everyone around them with the tounge kissing and shit like that. (Openly touching each other sexually in public, and stuff like that too. It's just damn nasty.)
The difficult part is I liked the gal I worked with. She was very cool, worked super hard, and did her job well. She has since moved on, and the last time I ran into them, my wife and I were out to dinner, and ran into them at the restaruant. (Crazy thing is, she was checking out my wife.. when I noticed her.)
Your sister-in-law's Lesbian friends sound pretty nasty. Either steer clear of them, or buy some beer goggles and see where it goes.
Just don't let them make out in public! It's too F'n nasty for words. (Ok, so like gay men doing it in public makes my nose curl up and I get the urge to hurl chunks, but that's another subject entirely.)
