Ok so I have found two websites that have a plethora of stories concerning some of my most very favorite literary characters... the first is:
There is both stories of the adult nature as well as stories of a more sedate nature. I have to say that I REALLY like the authoress of these stories. ;p And her current one concerning a locked masked ball has me sitting on my hands waiting for the next installment. :D
The second and final website that has SOOOO many variations both regency and current and for all the Austen stories is this:
Sooo soooo many stories...I have been quite hooked of late and completely forgotten actual books for the time being ;p
I can only hope that if you do investigate you'll enjoy them as much as I do!
