You don't!

get into the same things as her and flirt with her when your girlfriends not there. If she doesn't cos she doesn't want to hurt her sister then get them to fight with each other and then she might go out with you to get back at her. Or if your gilfriend gets on with her sister then she might go on about how good you are at snoggin! lol good luck...! and what d'ya mean you don't- every boy likes his girlfriends sister! lol
