So I [first confessed](https://www.reddit.com/r/gonewildstories/comments/h0cbfa/mf_how_i_started_fucking_my_sisterinlaw/) about how, a couple years into my first marriage, I ended up fucking my sister-in-law, who came across to everyone as a spoiled, snotty bitch. Or, to be fair, I should say that she often acted that way, but not always. But she also turned out to be insatiable. I knew that fucking her was a bad idea, but after a couple months of taut sexual tension, she more or less offered herself to me to fuck, and so fuck her I did. As has happened so often through the years, I couldn’t resist. I could never resist fucking other women. And as I wrote in my first post, I ended up fucking my sister-in-law Alice for 10 years.
When I described in the first part about how I made a drunken pass at her which turned out to spark this whole thing, and in the sober light of the next day I was freaking out about what I’d done… well, that had nothing on the angst that ensued after that very first hard fuck on the hallway floor. We’d fucked like a ravenous pair, I’d filled her with cum, and less that a couple hours later, she’s flying off on a two-week vacation with her husband.
