Looking for a story...

Hi guys,

I'm looking for a particular story which I have read somewhere:
A girl coming to a place to be tickled, paying money for it. The place is run by a kind of mistress with a female employee/slave named Barbara I think.
They tickle her together and in the end she is allowed to return for free.

Does that ring a bell with someone?
Thanks!
