It would be cool if there was a different type of game mode, like one where you are the dragon and you have to prepare for the layer by fucking or (more likely) being fucked by other monsters (or maybe weaker layer's).
The whole goal is to get their stamina to 0 before your pleasure is maxed, and, like with the layer, each time the dragon wins against a layer or monster they get to pick a card, which will make it easier for them to hold out and maybe even counter certain types of layers.
In the final battle with the last layer, which is basically the player character in the main game mode, the dragon has 3 rounds to make him lose.
