I've played a lot more of Fairy Picturebook, almost the exactly same game but with (a lot of) turn based combat. It's good but grindy, and sometimes pretty glitchy too. Looking at your avatar you might like one of the dlc girls...
hey bro...may i ask..where should i put characters DLC in? the instruction isn't clear enough...it said drop DATA_FILES into game folder but after i extracted the game, it is already there...
Just like you said take the DATA_FILES folders from the dlcs and drop them in the games folder (which does already have a DATA_FILES folder). If it's in the right place you'll be asked if you want to overwrite some files, say yes.
You can make the girls sit like that by holding down the left mouse key and moving down, but you have to do it before going into H time (as the left key becomes the interact key). Double right click them to turn them around. During sex you can hold left click on a leg to move it around, and pull up to make them raise their hips in the air.
Things like cowgirl, anal etc are selected in the ! menu. They have to be unlock though, and personally I'd keep cowgirl until last to unlock maybe (it looks really weird).
Edit - A example of the weird cowgirl position, also check the left side of the screen to see the sex toy menu open...

Click on status, then click on the girl and then on loyalty menu. You start off with only a few H requests available to unlock, but as you unlock things more will appear. I could be wrong but I think only Kokori has all the different option.
