I have spent the entire morning so far with the handle of a collapsible umbrella inside of me. The handle is as deep as I go and when I stand up, the weight of the rest of the umbrella pulls down and it is a pretty great feeling. I've been stuck like this until I can decide how I want to torture myself today. I have some bottles all clean and ready to go (shaving cream and hair mousse) and I have plenty of markers if I want to just feel stretched.
I have also been considering putting one...
