We facilitate lots and lots of different fantasies in the LDW Enchantrix Empire! As long as your audio doesn't deal with subject matter forbidden by Our ToS, I'm sure you could find a Mistress to record your script!
Keep in mind that most Mistresses won't be willing to record an audio longer than a few minutes for free! I'm sure you can understand that, since as fun as audios are, they do require a bit of work to get right!
Oh, of course! It's a short story but there are many words and it would probably take more than a few minutes.
