I just wrote a complaint about why NTR and NTS games progress so slowly. And now I see your comment. Are you serious, brother? Okay, I'm not saying they should be incredibly fast, but if my partner still gets embarrassed and walks away from a stranger's penis after playing a game for hours, maybe I don't want NTR/NTS. In these types of games, (I mean all adult games), the tension must built up to a certain point. When the tension reaches its peak, you suddenly drop an atomic bomb.And player relaxes. But if the NTR/NTS progress is too slow, the tension continues. Continues and more continues..the player gets bored. They start to question when they'll reach their goal.
Because of this, choose wisely what you're wish for.. Your choice of course, that's just a suggestion for me. Sorry, if I bothered you
