This story is purely fantasy.
My mother and father divorced when I was about 8 years old. My mother never dated after the divorce. She didn't feel that she could get close to another man in the same way as she did with my father. After the divorce I went to live with my mother. She is a fantastic mother and treated me very well; always encouraging me to work hard and do my best. She was quick to tell me how proud she was of my accomplishments in school and sports.
Fast forward to my 18th birthday. I'm looking to buy a car. My mother graciously offered to help pay for a portion of it. That was great news! What an amazing mother I have. One night, after several glasses of wine, she said that she had a special deal for me that would get the car much sooner. I was all ears, eagerly waiting for what she was going to say next.
The wine had made her enter into a sort of "truth mode" and her inhibitions just faded away. She said that she hadn't had sex in over ten years and missed it very much. I was surprised at her forwardness and couldn't believe what I was hearing. She continued with a "special deal" that nobody must ever find out about...
She said that if I agreed to have sex with her once a week, she would buy the car for me that weekend. What did I just hear?!?! I was absolutely thrilled to make that deal. This deal was astonishing. Hot sex with my perfectly sculpted, big breasted, sexy mother... and a free car! I was in heaven. Or maybe I was drunk, and I passed out while dreaming about my sexy mother? Nope, it wasn't a dream. Oh my, this is actually happening!
She continued explaining the terms of the deal. She said that she had started taking birth control pills. The reason? She insisted that I must cum inside of her each time that we have sex. Oh my, this seems too good to be true!
She continued, saying that every Friday would be our special night for sex. It would be her reward for working hard all week long. I was on board one hundred percent!
