In the dimly lit family kitchen, Siri, the naughty step-daughter, corners Vincent, her new step-brother, for a late-night snack. She's wearing nothing but a tiny nightie, her nipples hard and visible. Vincent, trying to keep his composure, can't help but stare as she bends over, giving him a perfect view of her ass. Siri turns, noticing his bulge, and grins. "Like what you see, big brother?" she teases. Vincent can't hold back any longer. He pins her against the counter, lifting her nightie and plunging into her wet, eager pussy, fucking her hard and fast, their taboo passion echoing through the silent house.
