First of all not every people on this god damn planet self insert themselves into porn game/movie positions, some of us just wanna see people getting fucked. Second i dont get why people use NTR as a term but skip other japanese terms like nukige.
And last of all you are already cuckolding your dad(or your god damn teacher's husband). So it is ok if you get to do it but it is not when someone else has option to do it? Nice self confidence there mate. Given you already stated half of the game is cuckolding and you dont like it, why are you playing/criticising the game? Just dont play or dont do the optional cuck parts and move on.
And please stop talking about about every cuckolding action in various games. You can skip optional shit and you dont have to play forced ones. I dont care if you get it or not, respect it or not. Just dont whine about it.
