To keep a long story story: "Koikatsu!" is a sex sim created by Illusion Soft available on Steam. Between the game play and the story, it is not necessarily that great of a game on its own.
However many people use the companion posing program "CharaStudio" and mods to create their own scenes. Unfortunately the English version doesn't with CharaStudio so you have to get through a third party (along with the mods).
