I’ve read a lot of fanfictions in the three years since I’ve first discovered them and these are just a few of them, the ones I’ve read most recently. Most of them, if not all, are rated M with some T rating in some cases. I encourage you NOT to read them if you are underage as they contain adult themes, coarse language and/or sexual situations.
The list will be expanding as I continue to read and enjoy fanfiction works from the NCIS universe…
