The Wildwoods (a sexfight progression roleplay (with an optional system) set in a forest full of monsterfolk)

Greetings!

I am looking to play out the following plot:

There is a strange forest, far from civilisation. Something within it radiates power into the woods, and this power transforms what lies within.

Animals, people, plants, and even stones or weather phenomena were anthropomorphised and given sapience. Furthermore, they were made very durable, with anything beyond scratches, minor cuts, or bruises being prevented by the power now vested into them.

They can take this power from each other by fucking the other into submission, and indeed that is the only real way to subdue anyone within the forest.

Besides stealing from others, this power can be attained by eating magical foods, absorbing magical gemstones, staying near places of power, and so on.

The more of this power you have, the more sexually resilient you become, and the better your touch feels to others, making it easier to best them in sexfights, but it also allows you to achieve impossible things, create magical artifacts, shrug off things that should cause damage despite the protections (such as not even having a twisted ankle after jumping off a cliff), and more.

The system for this setup would be maps, dice to decide winners of sexual duels (though I am willing to try something more experimental as the base, like poker or blackjack), and a leveling system representing the power (with levels being permanent for the most part but XP being expendable and stealable).
