Any dark romance recommendations?

You should look at the ''Gothikana'' by Runyx. I read that book long time ago but i still remember the smut scenes :ppp You know... Grown ass professor and new school girl... What could be wrong?? I can't remember the storyline but the book was so smooth, i remember that i finish that book in two or tree days. I hope you like that book too.  (English isn't my mother language btw (:)
