Ghastly's Ghastly Comic was built on this premise. (Although just the one-shot that started it, the long-running comic was based on the tentacle monster that said no to the thirsty anime girl because he has standards.)
You know, I was wondering what interactions most of these types of hentai images would have started out with or would have turned out as later on. Thanks BaalBuddy for answering my deepest questions!
