The siblings huddle together in the dark, their breaths ragged with fear and lust. The brother's hand trembles as he reaches for his sister's breast, cupping it gently, feeling the hard nipple poke into his palm. The sister gasps, her pussy clenching with desire as her brother's cock presses against her thigh. They're supposed to be praying, but their bodies have other plans. The sister's hand wraps around her brother's cock, stroking it slowly as he grinds against her. They're both fully clothed, their religious garments a barrier to their sinful desires, but it only serves to heighten their pleasure. They fuck through their clothes, their bodies rubbing together as they chase their orgasms, their moans drowned out by the sound of their father's voice on the other side of the closet door.
