I remember finding an RPG Maker game with a demo that was pretty good before. It started with the main character on a ship headed towards an island full of monster girls. As they approach, sirens hop aboard and tart kidnapping people, resulting in the pc being shipwrecked. You wake up to a very busty woman telling you how to play. It played like an rpg with survival elements. There were succubi that could be randomly encountered as your first enemy that have kiss attack. You could tame them by picking the right dialogue options, one of which is to accept her offer of a kiss and then agree to be her slave.
Sorry I dont have anything to show, but I looked for ages and cant find it.
