Here's a link to it.  Take notes, and I hope it works out better for you than it did for Jerry.

It depends on your playbook

..."I met some of her friends and they are smoking hot"...

T.I.P: That very statement from your post, could be the key to the lesson that you will be learning if you "use" her to get to her friends. It sounds like you have no issues "hanging out" with a girl whom as you described, not to be hot enough for your taste buds (I am paraphrasing) Well, no one is forcing you to date whom does not turn you on, but to use the proverbial cow to get to the proverbial calves, is not such a grand idea.

Question is, do you foresee having issues on your own in approaching hot women and is that why you need this "conduit" to facilitate the potential hook-ups for you? (indirectly of course, since she is going to be initially unaware of it) Or is it just too easy to tap into her resources of hot girl friends, instead of the more arduous task of hitting up on the hot women who you'll see at the mall, the coffee shop, bars, etc? If this is the case, you need to condition yourself to be able to meet hot women on your own, without being a user and abuser of other women, using the cow to calf analogy!

Nothing wrong with you going after her friends, as long as you do not lead her down the garden path to exploit her with the potential of causing her some lingering emotional damage. If you are only interested in her friends, man up and be definitive with her and let her know that when in comes to a friendship with her, your feelings are purely platonic. You'll be foolish to let her know from the outset that you are very interested in her hot friends akin to shooting yourself in the foot, but when she accepts you as a platonic friend, then there is nothing wrong with you courting her hotter friends. Exercising honesty is a crap shoot in this case, but if you hit the right dice combo, it could yield you even greater dividends and be like the gift which keeps giving

Flirting is acceptable.  Andif you flirt enough and be friends, she gets to introduce you to her friends, then go with her friends.  After all, you just flirted and didn't make her your girlfriend.

Her friends will think you're an ass...

...if you use her to get to them. Let's not forget that women are intelligent creatures and tend to see through this kind of thing. As others have stated, keep hanging out as "buds" to get to know her friends better. On the other hand if the clique is composed of treacherous catty backstabbing types, ie: frenemies, you can conquer one after another like Atilla the Hun and  move on once you are bored of it.
