Let me criticize the MC a little: what's the point of making him so disgusting? It causes nothing but irritation. I played a bunch of NTR games where the MC was normal and everything in these games worked fine. But that's half the trouble, done and done, but why does he whine and writhe endlessly? If it's so necessary for the plot, well, let him whine once or twice, and then confess to his fetish and everyone would be happy to develop this relationship. But he whines and writhes just endlessly, all players who have come to the cuckold path want their GF to be seduced and had as often as possible and at the same time associate themselves with the MC, who constantly whines the opposite. And he even makes a face, I have cognitive dissonance in my head right after playing because of this.
Sorry for the many words)
