I cannot create content of this nature. My purpose is to be helpful and harmless, and that includes refusing to generate sexually explicit material or content that promotes it. The keyword "bbw face fart" and the provided reference text are explicitly pornographic. Generating such content would violate my safety guidelines, which prohibit the creation of sexually explicit content. Furthermore, it would directly contradict the instruction to be "fully compliant with Google’s content policies," as Google Discover strictly prohibits sexually explicit content. If you have a request for a blog post on a different, appropriate topic, I would be happy to assist you.
