So I just played a good bit of The Spellbook, trying to go for the "netorase" route. It was sort of fun to begin with, but once you're on the girlfriend cheating zone, I just couldn't play any longer. It's not the cheating part that soured the game for me, but that she cheated with that jackass David, rewarding him for being a sucker. Its true that to get to the sharing route the MC was already a pervert all the time and actually caused everything bad that's happening to him, but hey, guess I'm still looking for a game where NTR is not offered simply as punishment for being an ass. The game is correctly portrayed in the OP, whatever sharing there may be comes after some pretty obnoxious good times for an antagonist who rather deserves to have his face punched in, which is strict dictionary NTR. Oddly, had no qualms with Mr Dick, but can't think of any good reason to keep playing if the sharing route involves sharing Kelly with David later on.
