Getting my balls beat on tonight!

The wife and I were fooling around earlier, and we got each other really going and wanting sex, but we honestly didn't have time. Ballbusting doesn't really do anything for HER, but after all these years, she accepts it's my fetish and will indulge it on occasion. Usually the hornier she is the more of a giving mood she's in. So she promised we would finish what we had started tonight, and I asked her if she would be willing to be REALLY rough with me tonight, and she just giggled and said "sure". We messed around a little bit more, and she gave me a few decent knees and punches, but promised she'd give me more later. Now I can't stop thinking about it and can't wait!
