Answering the door with cum on your face? Its a very hot idea for sure. I think what makes it exciting is the absolute naughtiness of doing it, combined with teasing the hell out of the lucky guy who gets to come to your door. There is no question what the lovely lady who answered the door was just up to, and she doesn't care that this stranger knows it. I think it is even better than the answering the door with a towel on and dropping it on the floor trick, though combining both would really be fun

Sounds like lots of fun - if you are up for it, go for it!
