Hi anon! We’re glad you feel comfortable asking us!
We’re not sure, admittedly, exactly where to find big bad wolf x little red ridinghood fanfiction. But we have some tips on where you could start looking.
There’s adult-fanfiction.org. Not a huge archive but might have what you’re looking for.
Literotica Since Little Red Ridinghood is a classic in the public domain you can probably find some stuff on here. Literotica tends toward less fanfictiony adult writing.
and furaffinity which has a lot of art and writing about furry and human characters, and probably a lot of wolf x red if you look for it.
Also some of our followers might know some other places. Please feel free to chime in if you have any suggestions.
