Heads up - this story is absolutely as fucked up as you think, and parts are more fucked up then even I expected... and she is keeping it "PG" for ethical reasons as to how bad the torture is.
If it starts to get too much - honestly, just stop. It only gets worse the further you go, and you get the point.
