Every Saturday night after the pub. We went to our friends house. We lived 12 miles away. The pub was near to their house. The idea was to watch videos until i thought i was OK to drive. Not fully sober. As it was in the early hours there were few police cars around. One was only a quarter mile from our house there was always a Police car parked in a pub car park. I always drove carefully past it. At the speed limit. Our friend walked out on his wife. Leaving her with the house. One week my wife asked me to call in on her. If i was close to where she lived. I visited her and we had a coffee. She is a plump lady with a beautiful face. A few times i visited her. I have always been turned on by white knickers. After watching girls at my Junior School doing handstands against a wall in the playground. The girls had to wear the school uniform. Of a pale blue gingham dress and white knickers. They had baggy legs and sometimes as i watched. I got a view of pussy. I knew my friend only wore big white knickers. I often saw them when she was bending. I was always turned on. One week i was sitting on the couch. She was bending to get in a low cupboard. Showing her knickers with her dress riding up her back. Exposing her lovely big bum. I couldn’t resist her. I stood up and moved to her. Pulling her knickers down. Dropping my trousers and fucking her. When i was having sex with her. I realised what i was doing. She could have shouted for me to stop. She could have pushed me away. She stayed there and let me fuck her. When i had finished i put my trousers on and sat on the couch. Not knowing what to say. She spoke first. She was thanking me. She told me she had been wanting to have sex for weeks. She told me that i could call on her at any time for sex. I admitted that seeing her knickers had turned me on. She told me to phone and let her know i was going. When i arrived she was wearing the big white knickers. I always pulled them off.
