Nezuko, the once gentle girl turned demon, finds herself at the mercy of her brother's carnal desires. Tanjiro, driven by primal instinct, pushes Nezuko onto her hands and knees, her ass high in the air. He spreads her cheeks, revealing her tight, untouched hole. With a low growl, he buries his face in her ass, licking and teasing her until she's squirming with need. He replaces his tongue with his thick cock, pushing past her resistence and filling her completely. Nezuko cries out, her body tensing as she adjusts to the intense sensation. Tanjiro grips her hips and fucks her hard, his balls slapping against her clit, until he can't hold back any longer. He pulls out and covers her back with his hot, sticky seed, leaving her dripping and spent.
