She knew someone was watching when she straddled Grandpa’s lap. No panties, no hesitation—just that thick cock sliding right up against her soaked slit. His fingers dig into her ass as she lowers down slow, then faster, until he groans and pulls her hair back to kiss her dirty. The couch creaks under their weight but neither of them cares who hears. Her tits bounce with every thrust while he grabs a handful and pinches hard enough to make her gasp. Then—when he flips her onto all fours—the way his cock stretches her open feels like punishment for teasing him earlier.
