Category NSFW?

Hey guys I was just curious if anyone knew of a way (or plugin) to restrict a SPECIFIC category (ie. my nudey babe of the week category) so that it can do an age verification, or just a notification saying there is nsfw content on the following page. I tried WP-Doors unfortunately that plugin only provides age verification for the entrance of the website, not individual categories.

For better understanding here is the website im talking about:

http://www.ragequit.ca

I would like for the age restriction to be on the BotW > NSFW section ( or even if possible, the BotW section altogether. )

Thanks for the help guys.
