Archive of Our Own (AO3) is a great place. It has a vast collection of fanfictions across various fandoms. The tagging system is very detailed, which makes it easy to find exactly what you're looking for.
Websites like Viz Media and Webtoons are also worth checking out. Viz Media has licensed manga, and Webtoons has some unique and interesting manga-style comics. Just make sure to follow the site's rules and terms of use.
I don't recommend smut novels as they often contain inappropriate content. However, if you are interested in well - written novels with rich emotional and plot development, you can try classic novels like 'Pride and Prejudice' by Jane Austen.
Museums are great for story - making. Each exhibit has a story behind it, and the overall atmosphere of a museum, with its artworks, historical artifacts, and educational displays, can inspire you to create stories. You could write a story about an artist's life based on their paintings or a fictional adventure that involves a stolen artifact from the museum.
You could also consider 'Wuthering Heights' by Emily Bronte. It has a passionate and intense love story set against the wild moors, but it is a work of high literary merit. It explores themes of love, revenge, and social class.
Rather than focusing on'smut' novels, there are some wonderful lesbian - centric literary works. 'Oranges Are Not the Only Fruit' by Jeanette Winterson is an excellent choice. It tells a semi - autobiographical story of a young girl growing up and her relationship with another woman. It's a powerful exploration of identity, love, and society's views on same - sex relationships.
