Bored and horny, the young sister spots her brother's growing bulge and sees an opportunity for some forbidden fun. She teases him, running her hands along his thighs, before pulling out his throbbing cock and wrapping her lips around it. She takes him deep, her eyes watering as she struggles to accommodate his size. Her brother, trying to maintain control, grabs her head and fucks her mouth, his teen sister eagerly taking every inch, eager to impress and satisfy him.
