Deal with a Demona cozy monster romance

Would you make a deal with a monster?

I need money. My rent is overdue, my aircon is busted and my bank account is overdrawn. So when I get an email from Monstrous Deals offering discreet well-paying clients willing to negotiate all sorts of arrangements, I’m not too proud to sign up.

Then I meet Rin. Impeccably styled, perfectly cultured and devastatingly gorgeous, this handsome billionaire is too good to be true. When I find out exactly what he has in mind, it’s even more unbelievable. Beneath his smooth, polished facade, hides a beast. A ferocious oni demon set on devouring one thing: my pleasure. Over and over again.

Will he demand more than I can give? Is that even a thing? Or will Rin be the answer to all of my fantasies?
