The landscape of online adult entertainment has seen a significant shift toward narrative-driven content, particularly within the "taboo" subgenre. Among the various iterations of this theme, the "step-family" dynamic remains one of the most prolific and commercially successful. Within this specific niche, the dynamic of the "step-grandparent" represents a distinct frontier, often characterized by exaggerated age gaps and specific power imbalances. Khloe Kingsley, a performer frequently featured in this specific subgenre, serves as a pertinent case study for understanding the performative requirements and narrative conventions of the "Not My Grandpa" trope. This paper aims to deconstruct the appeal of these narratives, focusing on the interplay between innocence, authority, and the "safe transgression" offered by the step-relation disclaimer.
