”I could hardly believe it when I saw it. Mom got down on her knees and put her face in my sister’s crotch. She must have been giving Mystique ple...sure because she started moaning again. When Mystique was having her orgasm she held Mom’s face tight to her pussy and humped at her. Mom sat back on her legs and just waited.Mystique said, “That was good. Thank you, Mom. Come back in fifteen minutes and do it again.”Mom left my bedroom and then Mystique and I got undressed. She was more than wet. As I finished off I looked down to see a pair of jess’ dirty knickers. These were not the sort I remember her wearing a few years ago. These were a lacy black number, like a pair I would normally see in a porn film. I was shocked because as far as I knew jess was not interested in boys at all, in fact rumours around school was that she was still a virgin at 17 years old. I picked them up to inspect them further. They were so soft and silky. I noticed that the crouch area had a pussy mark on. "No Sharon, I wasn't." I don't mind you looking at my arse, in fact I quite like it," she said smiling as she staightened up."You do?" Right, so you do admit it then."Ian blushed but did not answer."It can be our secret," said Sharon glancing at her brothers crotch.Later that day the pairs parents, Michael and Jane, announced that they were going out for a meal and told the siblings to behave themselves although obviously they had no idea of what was developing in Sharon and Ian's minds.With. After a short swim she dressed in sports bra and shorts for her morning run where she covered six miles every morning. It made her feel good to be able to run for twenty minutes strait. She could still run the six miles slightly faster than she did in high school. Joan stripped again when she got home. It was hard to believe her not yet 14-year old sun was better lover than her husband. He may grow another several inches but his 5-inch penis was longer when hard. He was very smart and already.
