my question is this, how do i make it so that she knows this wasnt a ''friend'l'y invite and that i want more?
As concisely as possible: you don't.
If you give a woman the vibe that you 'want' something from them, they will be turned off. You are also conveying neediness and beta behavior. What you want to do is make her as attracted to you as possible (gaming her). You should already be going kino quite a bit so she feels comfortable with touching you.
Never tell a woman "I like you more than a friend," especially when it is detached from a face-to-face conversation. I've made this mistake before and it turned into a train wreck. She asked for your number, she likes you. Just be natural, hug/touch her a lot, keep her interest high, and pull the trigger. Things will work out.
