Jorge is part of the main cast, he's literally on the main itch page of the game... and we just got an hand job scene with him after 26 chapters lol
And the characters didn't fuck during the treasure hunt, only a few scenes between the antagonist and some characters, also that event lasted for 3 or 4 chapters? If it was just one chapter for fun I'd get it, but come on. It made it not possible to follow through other character paths that are still yet to see any sexual development with the mc, like Mikhail, Kian, Feng, etc.
The author knows what we want, he's just not doing it yet for the sake of his patreon subscribers, even it takes more 2 years.
