I am looking for a story about a woman who meets a friend on a trip to chicago. Over dinner they talk about the last time they were together and how the friend and a guy had so much fun tickling her and how they wanted to do it again. The girl gets knocke out by an ether soaked rag over her nose and wakes up in a doctors office tied up and the friend and guy are the doctor and nurse who are going to tickle her again. i don't know the title to find it in the stories forum. please help.
