Wife gets bare ass spanking at birthday party

I have really been very fortunate! Mum and I, over the years, have almost never fallen out. For most of my years living with my mother she therefore had very few occasions when she needed to discipline me. I think she accepted that I had become sexually active although she did lay down strict rules about what was permitted at home and that boyfriends were not permitted to stay over night under any circumstances. She had pre-booked her trains and I knew that she would be away from the Friday evening until late Sunday afternoon. I had a lovely boyfriend called John at the time and we arranged for him to come to my house to sleep over on the Friday and Saturday nights.
