I'm wracking my brain trying to find my favorite penectomy story. I had it saved on instapaper, but then when the servers changed it can't access it anymore. I just can't remember the name of it. A group of friends goes camping, and one guy ends up having a dream about being tortured and raped. Burning sticks are used on him, a twig is stuck up his penis, etc. Does anyone know the name of this story?

Thank you.
