My wife and I live in Ca. and she loves teasing me in public with no panties on (see pic). When I tell her a guy is watching too, she knows how to tease slightly and get a reaction to see if he is truly interested and if he follows us. If he acts discreetly enough without drawing attention and gets in positions where he can see more, we know he wants more, and give him more. As for when to get close enough to allow him to touch, she waits on my queue and puts herself in the position to be touched. The vast majority of guys we have gotten to this level with will not touch though. So I feel her ass while he's watching and then walk off after whispering to her. The place and time and people around is very crucial to how far she goes too. Now we find a guy or maybe 2 prior to playing from our couples/swinger site and set it up, knowing where we are going and know where isolated places are to tease. I just love watching her do the teasing when a guy is looking, especially when she does it very close to him and we have decided to let him feel her. And once she gets hot, wet and horny, who knows how far she will go, of course with my approval. I can tell here of some instances when we have played, from barely showing her cheeks to a show salesman that was not shy at all.
