A bizarro double feature...
The first story 'Feeder' is a dark, disturbing peek into the world of gainers and feeders; grotesquely obese individuals and the people who facilitate their growth for the lascivious pleasure of both parties.
Your second tale is an affectionate homage to the much-loved Reader's Digest series 'I am Joe's Body', and a darkly humorous and bizarre parody of the Bruce Jenner story, this story is told from the point of view of a dismembered penis.
