Dommaxxximus, left alone with his sister, can't resist the temptation to explore her lush, curves. He slips into the living room, finding her sprawled on the couch, her massive ass on full display. He sneaks behind her, his throbbing cock already leaking. In a swift move, he grabs her hips, pulling her onto his massive member in a raw, doggystyle assault. She gaps in shock but soon moans, her tight asshole stretching to accommodate his enormous size. Dommaxximus pounds her relentlessly, his balls slapping against her, as she wiggles and pushes back, eager for more.
