As the preacher's son, you've heard the tales of sin and redemption, but never thought you'd be the one in need of salvation. Your sister, a devout girl with a hidden hunger, finds you alone in your room, her eyes fixed on the bulge in your pants. "You need Jesus, brother," she whispers, her voice laced with desire. She falls to her knees, her hands reaching for your zipper, and you feel the warmth of her breath on your cock. You know it's wrong, but as her lips wrap around you, you can't help but let her guide you towards a forbidden path of salvation.
