That Friday night we were very excited and very nervous.Here we were, only eighteen, and about to meet a couple who'd been into swinging for ten years... We weren't disappointed when we finally met them. Not for only the good looks but they were both very friendly and quickly had us at ease. You could tell they were very classy people. The fifteen year age gap certainly wasn't a problem because we were glad to have their experience to learn from.We went out to dinner and got acquainted and no one. I always knew our son had a fancy for his mother. Jess once confided in me after a few glasses of wine about our son’s strange desire for her body. She claimed that on many occasion, she had cleaned his room and found pairs of her dirty knickers stuffed down the side of his bed covered in dried spunk. She also revealed that Marcus would sometimes peek around her bedroom door while she was dressing to try to catch a glimpse of her nude body. Another little snippet she gave me was that Marcus had. Somehow this task had given her the idea she had stepped over a threshold. The second thing was her talking about not being useful and about a task. I didn't remember giving her a task. But then I remembered the double shibari. Had she seen that request as a task a Master gives his submissive? If that was the case she went faster than I had.The last thing was her request to being punished. I know it is hard to argue with a submissive in this state of mind. Telling her it was a misunderstanding. .. Sharon had put them both on birth control.When the new school year started, the two of them went to the only high school in the area -- Los Alamos High School -- becoming cheerleaders as well as excellent students.With the new house, Sharon was always ordering something to be delivered for the house.Although I'm 15, and the twins are now 16, I stay home and keep Sharon company and do anything for her that I can. Since moving here, I've had my final growth spurt - I hope - and I'm now six.
