hi Winnie - thanks a lot for your reply!

are you sure about the story being on storiesonline.net?
i created a (free) account there & did several category-searches; as those only show the first 10 results for free accounts, i had to narrow it down a lot - but no combination of storycodes i used returned the story i am looking for

the codes i've tried (in various combinations):
MF and Mf: definitely
Ff and ff: probably, not 100% sure about those
reluc: during the 1st part of the story definitely
inc, mother, dau: probably; not sure, if sis would also apply
les, bi, het: definitely
D/S, Mdom, span, BD: definitely
rough, SM: depends on point of view; probably yes
oral, anal: definitely
size: iirc there was a part about the mother modifying her daughters breast(size)?
harem: don't think so, but i've tried it nevertheless

as i've mentioned, no combination of those codes returned the story i'm looking for - even if there were less than 10 results, so either i didn't choose the right codes, they didn't categorize the story correctly, or the story isn't on that site;

any ideas how i could proceed? unfortunately the site doesn't seem to have a board, were i could ask the readers over there

thanks again - that was my first clue towards finding the story ,
