Cassie a friend of my daughters for years was just turning 19 and was in need of a new car. The one she had in high school was giving out and she came from a single mom family with only 2 younger sisters and no one knew how to look for cars. She asked me weeks in advance if I would help her on her 19th birthday look for a car for she had taken the day off from work. I worked for myself and could with advance warning take the time to help her. She was like daughter to me, I first met her when she was like 7 or younger. A pretty red head a little chunkie but not to big. Freckles with blue eyes and average built. The day came and she drove us to a few places but nothing worked out. We returned to my house late morning and my wife and daughter were gone for the day to work. It was if she really didn't want to leave and came in. Sometimes things at her home can be rough and its not uncommon for her to hang out at our place. This time she just won't leave me alone. It started with talk and then joking and before to long we were tickling each. I knew Cassie was very ticklish and before long just to stop her had to get her on the floor and hold her down. She moved my hands to her boobs and I didn't resist. I had been married 24 years never cheated but have always wondered what it would be like and it took no time for me to pull up her shirt to expose her boobs. I knew Cassie and how much she loved to tease boys in school and have sex with them. Her Boobs where so soft and warm and it wasn't long and she was sucking my dick as well. Very horny girl. I lead her to my marriage bed pulled off her pants and saw my first real shaved pussy and it turned me on. I licked it and before long had my dick in it. She moaned and came on it several times telling me to cum in her and I did very hard it almost hurt it was so hard. She was on birth control and we continued this for a few more month's one time an all nighter in a motel until she moved away for college. It was the only time I cheated and probably will be my only time as well but I will never forget.
