[sabrinaselentra]

I have tried to upload again and it seemed to work. I am on dial up. I uploaded for about 2 hours. Then I got the same old message wrong file type. I hope you can figure out why it is doing this. EMG to get the file get use this link: http://www.whispernymph.com/downloads/02Portal_return_pink_fairy.mp3. The description is: Asparaz-anel's Finishing Spell or The return of the Pink Fairy
Enchantment Series: The White Fairy; Asparaz-anel's Finishing Spell or The return of the Pink Fairy ~ This is the second of the Portal adventures in the series. Another night in the whispering wood where you are entertained by the Fairies and elves and get a special gift. The pink fairy is up to her old tricks and thinks your breasts need to be a bit bigger.
Please grab it and post it for everybody. Love Sabrina
