Ah! I havve very fond memories of this game the moment it was announced on the author's Pixiv page. Actually it was mired with frustration and impatience because it is literally the guy's first RPG work.
For those who do not know Bich Bokujou, he is a doujin artist specialized in NTR genre. I was iffy about this art style at first, but his Infinite Stratos doujin won me over. If you get into Bitch Bokujou's works expecting vanilla love story and such, you are a poor deluded fool.
About the game, it is a run of the mil unavoidable NTR game. Though it's tone is way more upbeat than the Thug Hero Party game. The gameplay is grindy but nothing Cheat Engine won't help. The art and the events are great though. True to Bich Bokujou's style, all the girls are slowly getting corrupted. With each mission finished the King will cuckold each of the girl and then proceed to corrupt them further. The true ending of the game is superb in that all the female presence in the protagonist' life is cuckolded. It is literally in the title of the game.
All in all, if you are a fan of Bitch play this game. If you a fan of NTR but not Bitch Bokujou yet? Check out his doujin works.
Who know? You might like it and then come back for this game.
