I think NTR/cuck games must have the widest range of what players want. If the dev ever does something like that I hope it's an optional path, because it would absolutely chase me off.I have been enjoying the latest chapters 17,18,19... a lot, and I really like that the game now gives you the option to opt out of raw sex and anal, meaning that only her bull has that privilege. I wish the game would let you choose to not have sex with Laura anymore though, it would be hot if there was a path where eventually only her Bulls can enjoy her body, maybe it can be something progressive like giving up blowjobs first or something like that.
FWIW, I suspect you'll have to wait until after the main story line is done for any possibility of her cutting the MC off. Just guessing, but from his commitment to it being mutual and loving and respectful of all involved, I think a path like this is too far off the map.
But I've been wrong before. Would definitely fit on the path where she's dominant.
