girl is forced in school washroom

[gralsritter]

It starts off with the girl getting raped in the school washroom, and at least one more time later on. I don't remember if it was one or more guys behind it, but it was a brutal story, describing every step of it in detail. I found it 1-2 years ago, so it should at least be that old.

If anyone has any idea what I'm talking about and point me to the right direction, I'd greatly appreciate it. Thanks.
