I have no idea what scene it it would have been. The 'gallery' for the game is terrible. It doesn't even give you an inkling of how many scenes can be unlocked. All it does is tell you how many character HAVE unlocks. Which isn't even remotely helpful.
I saw the scene guide. But all it really tells you is the same things the game does. Like 'make them submit' for a scene...pity it never tells you HOW to make them submit.
I'll try what you said later, if I don't just delete the game again. While it can be a bit arousing as long as you don't mind text (which I don't), the scenes require too much in-between them for me to actually finish. So I usually get bored, delete it, and go play one of the others I have that have 'useful' galleries.
I dont think is that hard, anyway usually in the game the monster can dominate you (by fucking you until they are done, making you lose the fight and sometimes getting another scene, a good example of this are the centaurs, since they are so strong almost everyone loses at the start and gets dominated) or you can make them submit to you (by fucking them, by being the top, meaning no blowjobs or taking it in the ass, sometimes without even handjobs).
There are also special cases like the first encounter with a female goblin (where if you have enough perception, agi, etc you can have a pretty nice scene where you catch her and fuck her ass), or the fights where you win and can fuck the loser (female goblin, but the scene is different than the one where you catch her, male goblin, the wereslut, where if you win you get fucked, etc).
Then there are the scenes that you need to be smart, like the dullahan, the witch of the manor, the golem, the ghost, the cultists, etc. In this case you can get the scenes depending on your stats (end, carism, agi, magic, etc) and knowing what to say or which checks to fail. (an example, if you go to the ruins with gloves, boots and helmet you can go all the way down, pet a small spider and start a fight with an arachne where if you surrender/beg/lose you can decide to be her lover and see a scene with art, BUT you need to complete all the checks to get to the bottom, if you fail you will encounter her but without scene or art. There's another in the altar where if you pray instead of defile the statue you get different scenes with an angel, from anal to pussy to orgy, etc)
There are also some scenes outside the fights where the stats and checks are also important, like the brothel, the inn, the tavern or your companions.
Usually i just save before doing something for the first time, so that if i get a check or an option i can always go back and choose again.
