Hey matt-c, so if what I'm hearing is right you want to use kino to move into comfort? Most escalation for me takes place when I'm in comfort itself. Before comfort I'll usually touch her on the shoulder when making a point and playfight a bit after teasing her (she'll usually punch me on the arm if reacting well).
From there once you isolate I'll be touching her in a whole manner of ways that all have one thing in common: its not the way you'd touch a friend. Eg stroking her back with a few fingers when talking to her or putting my leg up against hers when next to her. The tough thing, as you've said is making it seem natural, when you force contact it's often met with resistance. Just remember it doesn't need to be a massive gesture.
One thing to keep in mind when you do isolate/bounce set is to try and lead her by holding her hand, give her the option to take it. Once that's established any latter kino is easy
. It's not easy at first but once you get more comfortable with yourself doing it you wont need to think about it that much.Hope this helps
