I think people are confusing cucking with cheating. The game is tagged with cheating, and if you are having sex with 12 different girls, and impregnating half of them, then you are a cheating man whore. Not to mention that Victoria cheats with you, and even gets pregnant, and if you don't like the game, just don't play it and stop complaining. Its that easy. It would be nice to have a repeatable sex scene with Erevi though, because once she gives birth, she will reject you. That's why I have stopped my progress on the maternity wear quest.
