What you cannot undo

I was about to turn eleven when I transitioned from a little girl to a woman underneath my then fifteen year old brother while our parents were out attending a wedding. I've felt awkward around my brother ever since. Our parents & spouses have no idea of our history and I intend to keep it that way.

Ich (40) hatte während meiner Pubertät mit meinem Bruder gestreichelt. Wir hatten regelmäßig Blowjob, 69 und Analsex.

Selbst als ich nicht mehr zu Hause lebte und mein Bruder mit seiner zukünftigen Frau zusammen war, hatten wir geilen Sex in meiner Wohnung.

As a child my sister and I were coerced into participating in making several porn vids and other sexual activities on board sailboats in international waters.
Our parents and most of the adults got away with all of it because of their political connections both in the past and most definitely in the present. As long as those files are not revealed they are safe and my sibling and I live in a hell made of memories. 

When I was in my very early teens, I engaged sexually with each of my younger sisters several times without our parents finding out. I know I shouldn't of done any of it and I carry the guilt and shame. My sisters both obviously avoid me now as adults. 

When I was about 14 my maybe 9 yr old sister used to like to sit on my lap.  She often did it with a skirt or nightie on and no panties.  At some point I was fingering her and she liked the way it felt so I continued for some time, maybe a few weeks.
Eventually I felt like I had to have it and one afternoon when there was no one else home I took her downstairs to the basement and fingered her and then got my dick inside her tight little pussy.  I didn't last more than a few strokes and blew my young load in her.
Afterwards I was scared at what I'd done and I gave her a little gift and told her that no matter what, we should never do it again.
I was also scared that she could become pregnant but obviously that was completely wrong on my part.
Eventually I kind of forgot about it and she has never mentioned it at all and we get along great like any regular brother and sister.  I don't know if she ever told anyone about it but I don't think so.

So when I was like fourteen, I messed around with my chubby ten year old girl cousin a bunch of times and got away with it thanks to her keeping her mouth shut about all of it.
