Was reading Little Red Riding Hood to my little niece this morning - she's at at an age where she wants the same story read again, and again, and again. So it was in my head.
So, having left and then checked into my incall property, meet client who has a big thing about being told he has a really huge cock. After about 15 mins I zone out slightly... And said before I realised "What a big cock you have..... GRANDMA"
Don't think he'll be coming back!
