Request - Looking for Stories

[colinshabbers]

Hey,
I remember two great stories I read a while back and wonder if anyone knew what they were called or where I could find them:

Story # 1) A girl is being blackmailed by an unknown person, who had an embarrassing secret about them. She has to keep sabotaging other girls' clothes, stripping them to their underwear. Barbie panties may be involved or something like that.

Story #2) Has a climax at a school science fair and there is an explosion, a load of girls are covered in some substance they are told will dissolve their clothes (it's actually harmless) and so they all strip on stage.

Any help would be great. Thanks.
