Write Me Dirty

Write Me Dirty is one of those podcasts that makes you triple-check your earbuds are firmly synced to avoid broadcasting a moment of turgid titillation in public.

It's silly rather than sultry, as Katherine Ryan sets out her rules of engagement and asks two comedians to write an “erotic” story about their opponent and read aloud every smutty sentence.

Ryan eases the way by providing a location, character and a prop that must be included, but like the best audience suggestions in improv theatre, prompts never lead where you might expect.
