Corruption mechanics with a sprinkle of manipulation and some forms of NTS/NTR. Which in real life repulses me. I've had real women want to be my "step" daughter and to punish them, age play, S&M, etc and it all turned me off. In RL I'm very vanilla lol. Maybe that's why I went into medicine and neurology/psychology.
Harem with romance. If it's incest romance even better. And impregnation of course.
No stepcest of course because that's not incest and no other men. NTR/S is for repressed homosexuals.
I do like me some mild femdom. Also stealthy sexual acts/risk of being caught can be really hot, stuff like getting a handy behind the counter while having to keep up a conversation or something, maybe a bit specific but I love scenes like that.
