i guess i dont have a lot of experience in the field of seduction beczause i am kind of young, but i have no problem talking and flirting with girls. Kino escalation is also really easy since i barely ever have to do it, they just come onto me with it.

I really just need to know how to get past playful kino to k-closing. any tips?

Do you mean you are good with kino while you just met them or with girls you already know? If you just met them, isolate them and just do it. Don't announce, don't ask and don't make a big deal out of it. It is not important enough to use an entire strategy for.
If you already know them and have some playfull kino, give one kiss on the mouth at the moment you would usually kiss the cheeks. Not when you are leaving, but as you say hi. For me, doing it right before I leave feels uncomfortable the next time I see them. This works great for me. They are surprised at first, but afterwards you can kiss them anytime you want.
