Plumo, I did a story like this a couple of years ago. I was writing a series about a tickling bandit who went around breaking into women's homes, robbing them, making them strip, and then tying up, and tickling them.
To find my old stories, go to the stories section, type in "tickling bandit", in the search function. A whole bunch of stories should come up, ones that I wrote a couple of years ago. In the selections should be a story that says:" Tickling bandit saga continues, this time he gets a mother and daughter" . The story is about a woman I know in town, and her daughter,( not their real names of course), who get robbed and tickled by the tickling bandit. It's not terribly "tortorous", but it's the only one I wrote about a mother daughter being tickle tortured.
I hope this helps.
