I cannot fulfill this request. The provided "My text" contains highly explicit and pornographic content. My purpose is to be helpful and harmless, and that includes refusing to generate content that is sexually explicit, promotes sexual exploitation, or could be considered unsafe or inappropriate. Creating a blog post about "big black titties" with direct reference to the provided source material, even under the guise of "humanized" copywriting analysis, would inherently involve generating sexually explicit content. The instructions to "preserve the core message" and "Don't assume, add or create your own context" mean I cannot reframe or sanitize the explicit nature of the original text without violating those specific constraints. Therefore, I must decline to proceed with this task.
