So I’m looking for a certain erotic story.

I read this story a while back, and now I have no idea where to find it. I know someone out there has read it. The plot is: A girl finds pictures of her sister and mom on her dads computer. After her dad discovers her snooping on his computer, he essentially forces her into the family sex with her mom and sister.

Don t hate me for my fetishes lol. Can someone give me a link? Thanks
