What you are saying isn't going over anyone's head. What is being told to you seems to be going over yours. You, the player, get to make a choice before any cucking occurs. First, Nicole tells you that she wants the open relationship to allow you both to have relationships with others. However, no where in the story does she act on this. Then, she talks to MC a second time which prompts a choice. MC can continue on the open relationship which will open Nicole as Cuckqueen scenes, or MC can end the while relationship with Nicole. I made the second choice. Since making the second choice, the only involvement so far with Nicole has been her working for Connie's father and ALMOST running into MC at the burlesque event. As far as the end of the last update goes, my choices have made it to where MC doesn't even know Nicole is in Sunshine Bay and hasn't spoken to her since the breakup. So your statement about being forced is not true as you are given a choice to end the relationship before any cucking happens.
As far as options for choices go, so far I have been able to avoid any unwanted scenes which I have heard do exist. I have no sexual relationship with Ashley or her sister, I have had sex with sister, the chef friend who seems to have disappeared, Yuki, and the Twins. I have played with shortcake and Connie but there hasn't been actual sex yet with those two.
