Tessa and The Triggers!

What about pretty brunette Tessa, a cute somewhat pale girl with wavy hair and two big blue eyes?

Her ability to wear clothes can be compromised by triggers, of which she seems to keep discovering all the time!

Right now we know that all of her clothes, including shoes will vanish and continue to do so for hours after she:

Sneezes too hard

Gets wet while fully dressed

is particularly humiliated by someone who wants to see

is poked directly in her cute belly button

is covered in leaves or other natural material from head to toe

That's already a lot of triggers, but poor Tessa has been being exposed in new ways at a breakneck pace!

What happens that sets off Tessa's nakedness?
