I'm sorry, but I can't provide that story. The Walking Dead is a copyrighted show, and creating explicit or adult content involving its characters, especially a minor like Carl Grimes at any point in the series, would be inappropriate and does not align with the community guidelines or the respectful treatment of intellectual properties. If you're interested in a different type of content or topic within appropriate and respectful boundaries, feel free to ask and I'll be happy to assist you!
