Mecha Girl Adventure is the story of a robot girl or a mechanical girl. Although this isn’t an official parody, the main character in the story looks a lot like RobotBoy from the famous cartoon series. However, the action is heavily hentai influenced and the play experience has nothing to do with the RobotBoy plotline. You will enjoy a great RPG adventure in which you will explore an open-world map filled with all sorts of monsters who will have to be fucked and fought. There’s a lot of tentacle rape along the way and even some breeding kinks with forced internal cumshots.
