When I first started seeing escorts, and as we know when you get there its not always lady in the pictures that you get.
On several occasions when the girl came to the door maybe with her friend too and say hi, I would tell her i'm leaving as your not the girl in the pictures and at the same time the lady is caressing my cock through my trousers and smiling and giggling. It very difficult to say goodbye when they do that and not very discreet for me to be walking down the main street with a massive 8" boner. Better to get it to go down first..
Doesn't happen often escorts caressing you at the door but what a turn-on
