I'm rereading this and

1. 24 and 18 not much of an age gap there. They are way worst on this site.
2. Not incest, i don't know if you skipped through the remarried part and the fact that their parents were only married for max 6months.
3. What's wrong with student x teacher. They started dating before that title.
Pleases read and understand it. Don't scare away precious readers who are going to miss out of lovely stories like this.
