Seduce him in public where his opportunities to respond are limited. Firstly, dress just on the the tarty side of elegant. Look into his eyes, hang on every word he says, touch him, let your breast rub 'accidentally' against his arm. When you think you've almost got him hooked, tell him he's making you wet and horny.

You now have him in the palm of your hand. Tell him you've left your knickers off and if he can work out a way to do it in public, you'll let him see for himself. By now 100% of his attention will be focussed on your pussy and he will do ANYTHING to get his hands on it.

Good luck - wish I was there ----
