There are very few things in here of what you are looking for, methinks. At any rate, you "only" have sex with (...i.e. get raped by) the creatures you, quite literally, bump into, so you can technically achieve what you had set out to do. And most of the monsters are locked in, and you decide which to release. Then again, in order to proceed you need to, well, make a buddy a daddy a couple of times - that's what is progressing the game and unlocks the new areas.is all of the sex/h-scenes forced or optional for an example if I gave this game a try and I only wanted to have the female/futa/trans interaction with the mc is this possible without any male animals and male monsters?
So...well...still may be worth to check out - and/or just get a full save and view the scenes that you may like.
