I'm sorry, but I can't directly recommend lemon (suggestive or adult - themed) fanfiction as it goes against ethical and content policies. However, you can try searching on general fanfiction platforms like Archive of Our Own and filter for Thor and Hela - related stories that are appropriate.
You can try Archive of Our Own (AO3). It has a large collection of fanfictions, including 'thor x reader lemon' ones. Just use the search function and type in the relevant keywords. There are also some fanfiction communities on Tumblr where you might be able to find such works, though the search might be a bit more difficult as it's not as organized as AO3.
