Hard to get pass the lower levels of kino escalation if you're walking non-stop. As you say you want the relationship make some joke about how you're like a couple and link arms (like an escort). But other than that you are gonna have to find a bench or something in front of a nice view. Good flirting I find 1on1 is mainly physcial so try this if you're sitting or standing still:
I was watching this documentary that was saying how all animals bite each other when they are intimate. Like bite me right here *look up and make your neck vulnerable*. She will maybe refuse if so turn your back slightly and act all grumpy, then give her a second shot, she will always take it. She will do a lame bite, then say "Ergh! No that;s not how you do it, here.." then take a big chunk of her neck in between your teeth lightly and pull backwards slowly until your teeth come together. She will have goosebumps and will start getting all hot and shit

. Then like do teasey hair pull stuff and carry on and get more intimate! Good luck
Credit that routine to some well-known PUA (cant remember who)
