I believe I read a fictional story on this site about a man who ties up a woman (his wife?) and she is left bound and desperate to pee. Around lunch time she hears someone at the door, hoping it is the guy who will untie her and let her go to the bathroom. However, he has sent his female assistant to check in on her and the woman ends up tickling her feet rather than untying her. Does anyone have a link to that story?
