If they would have pulled it more, you could have had a happy ending...
a couple goes to marriage counselling... the counsellor says that they need to open up and communicate more... He asks the wife to tell the husband something personal...
She states, "If you want to have sex with me pull on my nipple once and if you don't want to have sex with me pull on it twice..."
So now it's the husband's turn and he says, "If you want to have sex with me pull my ***** once, if you don't want to have sex with me pull it 500 times...." :D
