It wouldn't. Neither would the MC designing a spaceship and everyone leaving for Mars. The point is that complaining about those things not being in the game is not logical. It is a netorase game. Complaining that it doesn't have something other than netorase is silly.The couple talked about an open relationship, that's a two way street. Please explain how the MC getting play and sending his own competing porn studio images to Laura instead of holding his dick waiting for her to leave Nathan's bed would prevent this from being Netorase.
If you find NTR grating, don't play games aimed at that kink. Complaining that it's not a swinging game or that the male MC isn't getting any on the side is just foolish. It is literally called "Netorase Phone." Not "Open Relationship Phone." Not "Swinging Phone." The only person it would be fair to complain about not getting any action outside the relationship is Laura.
