Looking for a story

If anyone can help, there was a ff/f story that i read about 6 7 years ago. It was written from the point of the lee who was considered the wild child of her group of friends. They want to learn more about bondage and she allows them to tie her up and then proceeds to TRICK them into tickle torturing her and forcing her to worship her feet. There was a game that if she said uncle within 30 minutes she would be bound and tickled every day for a week and of course, she looses on purpose. If anyone knows where this story is i will be eternally greatfull.
