looking for a story

[potatoe93]

I read a mom and son story here a few years ago can't remember the title though, the story was set in the seventies, the mother and son went to a concert together got high then fool around, the son had to constantly win over the mother again and again as she usually felt guilty, then the father got out of prison and terrorised them after finding out about their affair, eventually the get the dad sent back to prison though
