Cock Ninja, the anal expert, catches SmartyKat314 mid-yoga flow, her lithe body bent in ways that make his thick cock twitch. She welcomes the interruption, dropping her downward dog to climb onto his lap, her tight yoga pants no match for his eager hands. He teases her ass, making her moan as she grinds against him. She turns, facing him, and slips off her pants, revealing her glistening pussy. She mounts him, riding him slowly, her muscles clenching around his shaft. The taboo of their sibling bond only intensifies their pleasure as they fuck in the middle of the living room.
