You asked me about good smut books, but I think the author of the book blocked me so here we go: "Yes, sirs" by @CorneliaFields And "crisis of desire" by @shiaraxo are very good. They both are the first book of a series I think and they both are writing on the second book right now. But they are pretty long so you don't have the problem with long wait if you start now and the storyline and smut are great! You should really read those two, I love them, and I recommended them to a classmate(she's into smut too xD) and she loves them too, so I think is a good choice
