I read this a few years ago. It was about a married man who was cheating on his wife with his sister-in-law and their mother. While the plot sounds similar to Katekano, Musunde Hirate, or the Shimoedas, it's none of them. The MC is kinda a dick from the outset, he had sex with his wife and sister-in-law in the first chapter (the only chapter I read), and it didn't have a vanilla-ish feel. IIRC, they all lived in the same house. Any help would be appreciated.

Bumping this.
