I got this idea when I saw an ad for a dog sitting service. What if a young woman dog sitter was hired by an older woman to dog sit her 'disobedient mongrel'? The dog turns out to be a naked man on all fours wearing a dog mask, and a leash. He's also wearing a butt plug tail and a cock cage. The dog sitter wants to leave until the woman pulls out a stack of hundred dollar bills. Not sure which direction the story could go from there. Anyone interested in fleshing out a story from this kernel of an idea is welcome to grab the reins and run with it.
