I just played this game today and if by priestess girl you mean the head priestess or whatever, you gotta kill ten of the NPCs with the overworld model of the fancy long chinese hat that always enter battle as an old pope dude. THen you can fuck the head priestess. From there you can g onto the castle which is where I got to and got the princess.
No idea how to fuck the princess but I assume the dialogue before you leave contains a hint. Also in the top right after entering the castle from the ground floor door on the right in the stable there's a little RPG maker glowy pick-me-up item that when you get lets you fuck the sorceress girl.
From there you have to go through the side dungeon and beat the demon lord if you want to fuck the heroine. Good luck with that, I stopped caring myself.
Also what the fuck is with the thread on ULMF it's filled with a bunch of barely literate retards.
