Longer version of mandy

[obegui]

Hi There.
Many years ago I'm sure I read Mandy by Amanda and Julie but the version I read there was a lot more to it it was much longer than any of the versions I have since found all the versions I found end with Mandy and Pam being picked up by Mandy's mother from the orphanage/school. but I'm sure I read a version that continues after that where they end up as maids for the mother and her lover then the lover after the mother dies and finally Mandy ends up serving Pam. was it a sequel or a new story inspired by Mandy.
So if anyone has any idea It would be greatly appreciated
the original is still on storysite but I can't find the longer version

Thanks.
