A humorous yarn, but a few problems:
a) They knew her as monsterous prior in a variety of ways, just not rapey. They saw problems before but feared confronting her, each for their own reasons. Divided we were all victims of some sort.
b) She aborted it before I even knew about it, so there was no child support risk.
c) I've fucked what people could consider "fat chicks" prior and following without problem, and that wasn't a secret.
Anything else?
