Assuming this is a chick I never smashed,,what I do is have them at my place with a movie on and some drinks then I say to her "do you trust me ?" ...and they will say yes cause they already at the spot getting tipsy.
Lets play a game and see how much you trust me..she will agree cause she is curious and anxious at the same time. I put a makeshift blind fold over her eyes sit her down on the couch and stand in front of her and rub my two fingers across her face like it's a dck.
If she bout it she will attempt to suck or kiss on it anyway and you good. If not she will freak out and you joke like you really thought I would try you like that ?..and before she can answer you say "i'd try you like this" and then make whatever move you wanted.
