Ai Suru Tsuma no Ana wa Tanin no Ana Datta... Bishiri o Sashidashi, Aniki no Nikubō o Onedari Suru Midarazuma

This Japanese erotic visual novel is about a man whose wife starts cheating on him with his brother.

The player takes on the role of Hiroaki Shinomiya, a man who has recently gotten married to his loving wife, Yuzuka. When Hiroaki's older brother Ryuuichi, who works as a freelance writer overseas, lets him know that he is returning to Japan for about a month, Hiroaki offers to let him stay with them instead of getting a hotel. While at first the arrangement seems like it works for everyone, it soon turns into Hiroaki's worst nightmare when Yuzuka starts having sex with Ryuuichi behind his back.

The player may make choices throughout the game, but all choices result in a single ending. Yuzuka is voiced by Riku Kobato.
