I'm against the type of guy that just wants to 'bed' chicks, however your young so this shouldn't be a problem.
The trick is to when your first meeting them establish a high level of contact.
What I mean by that is don't just greet them vocally, kiss them on the cheek or lips if you feel you can pull it off, followed by an immediate hug.
What this does is puts you on a rather high escalation level STRAIGHT away.
Which means you barely know her and yet you'v already kissed.
Making, making out seem almost trivial and higher escalation possible.
The moment you see her, how you act sets the tone to what you can do.
I mean if you can't make out with her, you can't 'F close' her.
Once you'v gotten the greeting out of the way, it's important to constantly increase the kino.
BUT!
Since your giving this girl so much attention, you make sure you keep, spinning plates right infront of her.
So that you don't seem needy or desperate, this is where most guys go wrong, they set there eyes on one girl they want to close, which means you give the power to her.
So game other girls infront of her, as well as her.
Some good kino ideas are:
Play with her hair.
Let her hair down.
Mess her hair up.
Poke her, you can even poke her boobs if your good at what you do.
Spin her around.
Hug her.
Caress her.
Play with her clothes.
Bump into her 'accidentally'.
Hold hands.
Lean on her.
Shake her.
Play hit her.
I don't care how you pull this kino off, we all have our ways, ill give you some examples of how to pull some of this off.
Shake her: Cry earth quake.
Hug her: Im cold.
Play with her clothes: I like that top on you.
Let her hair down: I like girls who let there hair down, don't be so uptight.
Get creative, use what works for you, these examples are off the top of my head which I pull off constantly.
and then there's just kino that you don't have to explain and should come with the situation, like say you bust on her then she busts on you back, you could play punch/push her.
I'm pretty much the master of kino.
I know it's hard to get the context of how stuff works.
If you want to learn more about kino, watch big brother man, there all naturals at it, seriously how they act is very interesting.
In short, fast escalation is achieved by climbing the stairs 3 steps at a time and taking a risk of falling down by doing so.
