I was at a babysitter's when I was 8, my autistic brother (2 years younger) went as well.
My babysitter was always on her computer and believed her kids over the kids she was supposedly "looking after".
One day, her son (2 years younger as well I think) and a 5th grader conered me in the basement, the son locked the door from the inside of the basement but kept look out. The 5th grader cornered me and tried touching me in inappropriate places, he tried bribing me, and so on.
Eventually it happened. This happened whenever I was left alone with the two of them in the basement, one time I escaped upstairs and as a "warning" the son went after my brother who I would do anything for. So, I allowed these two to touch me and did as they pleased (no intercourse, to my memory) because I didn't want them near my brother.
At the time it was extremely hard finding a babysitter for someone with special needs and my parents worked for the government so they would be working most of the day.
13 years later, I still get flashbacks, dreams or memories of the incidents. I've only dated 3 people (including the one I'm with presently) the last two being well, assholes. Whenever they'd touch me I'd think back to those moments in the basement and I'm even now despite being with a very nice caring guy I'm still plagued by the memories.
People would make fun of me because I wasn't sleeping with whatever boyfriend I was with at the time and even went as far as to make fun of my trauma, it killed me.
I have moved past that complication but the thoughts still pop up in my mind from time to time, and I guess I just don't want it to become a more frequent memory...
