I often ask myself how far thoughts should and can go, especially when they are taboo. In this context, I remember a story that I would like to share. I was still a teenager when my parents were not at home and I curiously looked around their bedroom. They usually used to lock this room, but this time they had forgotten. I already knew that they had various things like vibrators and love toys in a desk drawer, but this time there was a USB stick next to them. Curious as I was, I looked at the contents and saw a video of my parents naked by a quiet lake. My mum was spreading her legs and my dad had an erection, I could see their genitals very clearly. It wasn't really much more than that, they weren't having sex or anything. I closed this file in shock, but then I was curious and watched the nude scene again. Then again and again. It was totally uncomfortable for me in a way to see them like that and nevertheless it turned me on so much that I masturbated at the scene until I had a heavy orgasm. I was ashamed afterwards and I still can't get the images out of my head. And to this day I still wonder whether my reaction to it was normal and what you perhaps would have done.
