In the confines of a cramped closet, siblings find solace in each other's arms, their religious upbringing be damned. The brother's dick tents his pants, his sister's eyes widening at the sight. She reaches out, tentatively at first, then with increasing confidence, stroking him through his clothes. He groans, his hips bucking, and she smiles, a sense of power coursing through her. She unzips his pants, revealing his hard cock, and takes it in her mouth, sucking him deep. He grabs her hair, fucking her face, his hips moving in a steady rhythm. She takes it all, her eyes watering, her pussy dripping with arousal. They switch places, and she straddles him, impaling herself on his cock, riding him hard until they both come undone.
