The cumming of a new sex god

This is an idea that I recently got, through the inspiration of a manhua (a Chinese manga/comic), in case you are interested, it's called reaper of the drifting moon and has nothing to do with sex.

Anyways, the world is in a "medieval" time, and so it has a lot to do with martial arts and such, in my idea that would basically all be sexualised, and the start of it would be that a lot of people (teens) get captured and locked up in a secluded cave that nobody can get out of to train them for several years, many of them will die through starvation or punishments and other captives. The main goal of the captors is to get a group of just a small part of them to be the strongest of them, so just 30 at most will survive in the end before they get released, what they do from there on out depends completely on you. maybe you are even the only one that survives before getting free again. 

What the groups goal is, to make the strongest sexual-martial artist possible, to control the world at some point, through you, but if you take revenge in them or do as they say, depends, like I said, on you.

regarding preferences, this is mostly a dark setting, so gore, rape and such will be included, but I, myself, am just fine with it in a non-sexual way, like, if someone get's killed or raped, doesn't turn me on, but for 5he sake of story it is amazing. Also any link is fine with me in this idea, so anyone that is interested, drop me a DM to discuss it.

And of course, I am willing to also answer questions in the comments.

I'm looking forward to hearing from you!
