My Mother And I.

When I was 14 my addiction was playing with myself. I would pull myself sometimes twice before school. I was super horny and quite kinky as well. The more unacceptable by normal society the more I wanted to do it. Luckily my sister was also like this and we began having unprotected sex from soon after she started getting her periods. I fucked her daily sometimes several times a day. I never pulled out, and fortunately she never fell pregnant. She was 13.
I also was a bit dumb and thought you could fuck someone in their sleep and as long as you were quiet and did it slowly. In summer it's not uncommon for our family to lay around the loungeroom together naked. No sex, just naked because it's hot.
There was just one two long couches in a "L" shape. So it you didn't want to be lying on the floor you layed next to one of our parents. Traditionally, my sister cuddled up naked with my naked father and I would do the same with my mother. One hot evening we were all in this position and fell asleep, I woke up and could tell that everyone was sound asleep and still naked. My sister was 13 and had her naked pussy spread over Dad's hip while cuddled up to him asleep. My sister told me after we started fucking that dad was already fucking her and had a bigger dick than I did. He also like me was taking advantage of her being on the pill and cumming inside her everytime. Maybe they had been having sex while we were sleeping. I can't say. These thoughts started giving me a boner.it was only then that I noticed I was spooning my naked mother. I imagined sliding my cock inside her while she slept, then realised how easy that would be. My cock was already up against it. I just thought if I moved slowly back and forth, going a fraction further forward than back each stroke. I could easily make it happen. So I began. Quite soon I was sliding my erection along my mother's pussy lips. I still don't know if it was my pre-cum or her juices but sliding got better as things got wetter, and I gradually went from rubbing against her pussy to pushing the tip in and out. Then a little deeper, and so on, until I was as deep as I could go inside the same vaginal canal as she had pushed me out of without pushing her off the couch.
She didn't move the whole time and I didn't last long. Before my body began jerking and twitching as I fully nutted inside my mother. She still hadn't moved and now I was frightened she would wake up as I was pulling out.
I slowly slid out and some baby gravy definitely tried to follow my cock. I got up carefully, went to the toilet, then to bed. Thinking it worked and I had successfully fucked someone in their sleep without being caught. My mother never said anything or even acted differently afterwards, but as time went on I figured she must have known maybe not at the start, but without questioning she would have been pretending to be asleep by the time I was inside her.
Definitely once I came, that was evidence that someone had fucked her. She obviously knew but has never once said a thing.
I only did it once. Then stuck with fucking my sister, when she was awake. At least she was up for it and moved when I fucked her. Plus she liked it when I would cum in her.
