The MC in MCStories.com is short for mind-control, and site houses a large and free archive of erotic and adult stories revolving around this very theme but also with a whole assortment of other fetishes and kinks thrown in.
The majority of the 15,000 available adult stories here involve some mind kind of control, and they're overall sorted according to 26 different categories. The categories include science fiction, comic book superheroes, time stop, watersports, furries, enlargements of bodies and parts, humiliation, incest, lactation, masturbation, robots, and so on. MCStories offers all the material as is, without editing or grammar checks, so you'll come across mistakes in the texts themselves and variable quality since most of these come from amateurs. In the end, you get everything from relatively tame to extremely graphic, twisted and depraved stories which can be from 2-3 thousands to over 10 thousand words long.
This site is clean with a very minimalistic design. You can start with the FAQ, or list stories in A-Z manner by titles and authors, but there's no search option. You can also check out the categories which have a slight learning curve to them because of abbreviations and color codes which make it easier to browse stories later on. Apart from that, you can check out lots of readers picks on MC Stories from some, we suppose, notable users that come with short descriptions. Moreover, you can list recent additions with dozens of stories and chapters added every week. Last up are two forums dedicated to mind control adult content where you can chat with other fans of the genre, share your work, and develop your writing skills with contests and challenges.
If there's a better archive of mind control sex stories than what MCStories, we'd like to know. Besides, this place is relatively easy to use, ad-free and offers two forums and many active users.
