I'd have to be way too ******* to allow a guy to finger me where other people could watch. I'd probably allow him to do it for a second. Long enough for him to lick his fingers and taste me. I wouldn't immediately follow him to a private fuck place... but keep him on the dance floor. The more horny a guy is, the better they dance. Gives me a chance to appreciate how he moves on the dance floor before he is moving deep inside of me.
