Look, it all depends, there are no cut and dry rules with kino.
One thing you do need to understand it needs to be integrated with a lot more. It CANNOT work independantly of a lot of other things.
Imagine trying to kino when conversation is awkward, when you have weak eye contact, when your body language is all ****ed up, when you are all nervous. It aint gonna work. Its going to backfire.
Anyway lets just assume you have the rest of your **** together. Kino should be natural from the beginning. There should be opportunity to touch naturally. Shake hands when you meet; when you hand her something, touch her hand; when you are going somewhere, indicate where to go with touch not words; when passing her gently place a hand on her as you pass; when sharing a joke slap her leg with amusement, when she is telling you something of emotional content place a hand on her in a comforting way; when she teases you wrestle her, when you disagree grab her in a fake attack...
Just do it in a natural and casual way. If she touches back you'll know to escalate. If she moves away or seems awkward, I'd cut that **** out.
