Kevinho, home early from the studio, pushes open the bedroom door to find his sister sprawled on the bed, fingers buried deep in her dripping pussy, her other hand cupping and squeezing her full, swaying breasts. She freezes, eyes wide, as he takes in the scene, his gaze lingering on her glistening folds and hardened nipples. He kicks the door shut, his voice a low growl, "Don't stop on my account." She bites her lip, resuming her rhythm, her body writhing as he watches, his cock straining against his jeans. He unzips, releasing his hard, veined length, and begins to stroke, his eyes never leaving her as she brings herself closer to the edge.
