oh...no question I'd tell the sister. She needs her ass kicked lol If you don't tell her and then you spill all the stuff at her a year down the road she's going to think you werent telling her because you also felt an attraction. Don't let the incidents pile up or go on forever. Say something like "you know I like having your sister around but when she spent the night the other day she came out of the bathroom without a shirt on and it really made me uncomfortable...she might be comfortable being naked around strangers but I'm not comfortable with it" and she'll probably flip out and be like SHE DID WHAT?! but just say "yeah I just figured it was something she always did but she needs to remember not to do that at our house" don't say anything about how you think she's hitting on you or trying to get your attention. if she says "has she ever done anything else like this?" play it cool and say nothing I can think of. Let her handle it because SHE will know that's what she was up to and she'll lay the smack down herself and you can be all "oh I don't know if she's doing THAT or not" and let her be the one who thinks the sister is acting like a spoiled little slut...but DONT overly take up for her either just say "well you know her better than I do I will let you handle it" and then LET HER.
Mention something to the sister. You don't want to create an issue between them if it can be resolved between the two of you. just make sure you have an answer if she says "lets go now". haha
Tell her sister that you're faithful to your Girlfriend and that you'd appreciate it if you didn't tempt me.
