"Remember, no sin is too great for our Lord's forgiveness," Michelle whispers, her breath hot on her brother's cock. She opens wide, taking him in, her tongue tracing the veins of his shaft. He gasps, his hips bucking slightly, lost in the sensation. They're bound by blood and shared secrets, their bodies entwined in a dance of desire and devotion. Each bob of Michelle's head is a prayer, each thrust of her brother's hips a silent amen.
