I really understand you, young people. After all we've all been teenagers and I know how you feel at that age about "sharing". I may even have a rest of those feelings in me still
But the D only , the "vanilla" route was in fact finished at the end of Ch2. Mr Dots only "forgot" to make an end for it at that time or.. was trying to keep also the fans of monogamy in the game (yes "visual novel"), on a separate path, while moving on these other routes. Which obviously doesn't work because the differences between these 2 groups of fans are too big.
If he could manage to not mix up the directions as it seems he does, and would keep that D only route "clean" from any perversions, for the fans of monogamy, while also developing the other routes stronger and quicker, for the rest of us, it could work but for some reasons he doesn't seem to manage that.
As for this becoming a "cuck fiesta", no , open relationships, swinging, polyamory are not only NOT NTR but they have also nothing to do with cuckolding! If this was really a "cuck fiesta" I would join you monogamists in leaving
. But it's not.. Mr Dots should just try to keep the routes clean from interference.
Once you chose to not see "sharing content", you indeed shouldn't! And when i chose to see such content, I should really see a little more than just a hand of Martin on some body part of D, another hand of Ryan on another part of D and some "dreams". And this while F keeps fucking around like a hero.. Which for the monogamists BTW, doesn't seem to be a problem..
