I have a post on my profile that explains the situation more but basically me and a girl (who's 10 years older which I view as a positive since she won't play games) have been friends for over a year, without too many details I'm going in to this mentally thinking she'd be down to hookup but I haven't flirted back enough to make it happen in the past.

She'll be watching my band play at the bar beforehand, and I plan to be as confident as I can talking to her before our last set, and start being more flirty with her than I've been in the past. Which I have no experience doing tbh, my buddy gave me advice to try and pull off the arm touch before heading back in, maybe cutting the conversation a couple minutes short as an excuse to "stop" her and do it.

We'll be at my friend's house after for drinking/bonfires/general partying stuff and we tend to party until the sun's up. I have zero idea how to make a move at this point though. My friend (not the girl, but the guy who's house we'll be at) gave me his blessing to use a spare bedroom that would be out of the way from everyone if we went there. What's the typical stuff to do in this situation? There might be too many people around to try kissing her when we're outside, and while pulling off a kiss would make it easier to escalate, I kind of want to just be direct and just...ask if she wants to fool around? I know there's also the typical line of "want to head to the bedroom" but somehow I don't know to deliver it non awkwardly.
