Uncharted Lust: Brother's Throbbing Surprise

The siblings' hidden desires bubble to the surface as they're forced into close quarters. The brother's massive cock tents his pants, drawing his sister's gaze. She licks her lips, her pussy clenching in anticipation. She reaches out, rubbing the bulge, feeling the heat and hardness. He grunts, pushing into her touch. They're playing with fire, but the thrill of the forbidden is too intoxicating. They're about to give in, to fuck like the siblings they are, but the creaking floorboards outside hint at an impending interruption.
