There were two stories I remember reading but can't seem to find anymore.
The first one I remember the name was Webcam something. A father finds his daughter has a Webcam show and blackmails her to scare her. He comes to find out she is being blackmailed by someone else and so is his younger daughter, his neighbor and her daughter as well. The ending has the father calling a FBI friend to shut it down and they go to a club where the daughters are going to be sold. the older daughter is made to fuck dogs. This is not my private camwhore or part of the Tumblr stories. This is the second post looking for this story
The second story is about a Father saving some girls after a divorce, later he finds out that his daughter is being sold by the ex wife's boyfriend or step day. she is tattooed with an angel tattoo to mean she can take someone to heaven with her body (this is a line I remember reading).
