This is a major fantasy of mine. Wife can't help since I need to make her explode for her to be ticklish so it would be backwards. I do have a friend who let's me use her as a surrogate for my fetish but there is no sex at this point. She did tell me that there are times when she and her hubby are having sex after a long buildup or long foreplay her pussy gets so ticklish he has to stop and let her calm down. She is really ticklish and the cool part is it's in so many different ways, soft, hard, pokes it all works.
