Yet another "Looking for a story" thread

Hi,

I have been driving myself slightly bonkers looking for a bondage story I read a while back. The story is about a female submissive that responds to an ad on a bulletin board of a local sex club. The ad wants a cum slave for a night. She goes to the male's house, where she is connected to him, via a special head harness and is forced to thorat him overnight, including during urination. She finds that she loves it and wants more.

Anyone have a title/author?????

Please?????????/

Thanks
