Ok, so here's the gist of it. I am 19, a virgin, and extremely inexperienced when it comes to women. I've never gone farther that a K-close and only gotten there twice. I can keep my cool around cute girls, joke and such but I always am a coward when it comes to making trying escelate kino or anything really beyond playful flirting. Tonight I've decided to say fuck it and actually make a real attempt at this.

Anyway so tonight a couple of my sisters friends were over earlier tonight, HB7 and HB8. I've known the HB7 for about four years and the HB8 I just met a week ago when she stopped by real quick with my sister. If I had an opportunity to score with either of them I'd take it in a heartbeat. However, the HB7 is my sisters best friend, shes over a couple times a week, so I'm not sure how that might affect anything.

So here's where I'm at now. They left a few minutes ago when my sister had to go work to go to HB8's house and will be back later tonight when my sister gets off work in 2 hours. There may or may not be other guys/girls with them when they come back. The HB8 was laughing at some of my jokes (I teased her about eating cereal out of a cup). We made eye contact a couple times for a few seconds. The only other information I can think of that might be relevant was they were all smoking (pot) earlier, hence cereal and I know they are probably going to smoke again tonight. I don't smoke but don't have a problem being around others who are.

I'm normally a total coward in these situations, I just sit back and avoid any sort of individual interaction with a girl after this point but tonight I decided to say fuck it and go for it. So I got a couple hours till they get back. Any advice?
