Lookin for a story

They story goes something like:

The main girl of the story has volleyball practice, and gets picked up by her brother. They proceed to go to some church thing, as the leader calls her into a back room, to get “more appropriate clothes” ehich leads to her putting on MORE revealing clothing, and her being locked up on the desk, and being “cleansed” by the leader dude, his secretary or something, and her brother.

Been looking for this story for a while, any help is appreciated!!
