Bored and curious, a horny guy finds himself face to face with his stepsister, her eyes locked onto his growing bulge. She teases him, asking if he's thinking about her. He admits the truth, and she shocks him by dropping to her knees, yanking down his pants, and burying her face in his ass. She tongues his hole, making him squirm and moan, her fingers digging into his thighs for support.
