I laughed when I saw the title, and I clicked on the link just to see if the story was completely ridiculous.
But it seems pretty promising, I like the idea of each person having a major flaw to be exploited.
I think this sounds mostly dark as well, but you're hearing this from a person who prefers non-con stories with lots of bondage and pain.
This is also a great opportunity to get creative, but I'll leave that up for discussion.
