After reading what Triple-Digit is supposed to be I have to say that I'm right in that niche with you. Extremely casual sex so normalized that people just don't care and are more fascinated by the logistics is something I don't think I've ever seen anyone else be interested in. It's sexy AND funny. I really hope you do manage to get around to it. You could pioneer a whole new genre of porn.
We can cater to the entirely unrecognized market of all ones of people who'd be into it!
