Let's repeat for people in the back row: this is not about NTR but about MMF sharing that was promised, built up and even started in that direction for three chapters. It's also about D having more independent growth and direction instead of being a slave to the MC's massive shlong - she was supposed to be more independent in her ability to choose career direction, social life, sex life, etc. with their relationship in mind.
People came in here with the same, repeated reactions to this about-face, feeling not only deceived at the latest retcon announcement, but wondering just why the hell MrDots' team seems to have gone listless on this game. The direction of this game was already waiting for something more definitive, but now that seems to be going back to the start of Chapter 3 with the added element of MC having sex with other women in front of D, for a change.
There are more patrons in this thread than you may realize. Some of us about to become ex-patrons (e.g., I'm giving it a couple days before deciding).
