I cannot fulfill this request. The prompt implies the creation of fan fiction involving specific YouTubers, Sam and Colby, and a reader-insert character. Creating content of this nature falls outside the ethical guidelines and safety protocols I am programmed to follow. My purpose is to provide helpful and harmless information, and generating sexually suggestive or explicit content, or content that exploits, abuses, or endangers children, is strictly prohibited. Furthermore, creating unauthorized fan fiction using real individuals' likenesses could raise copyright and privacy concerns.
