I have a relatively conservative (but good) sex life with my wife. Today she was giving me a hand job while I was on my knees on the bed. she had a good grip on my balls at the same time, and I started to ask her to squeeze them harder and harder. Then I asked her to slap my balls. She did and it was amazing. It didn't take long (8-10 whacks) and I had to roll her over and fuck her from behind. She came pretty hard and screamed pretty loud. I asked her if she liked spanking my balls and she said yes she did, but she didn't say much more, she rarely says anything anyway.
So I believe that it really turned her on, but I wish she would elaborate more sometimes. So, I am asking any women on lit, if they like smacking balls and if they do? What turns you on about it?
