Wish your Mistress a happy holiday by pleasing her in the most devoted way. Begin by expressing your adoration through licking her ass, ensuring her satisfaction. Freely offer your mouth for her to use as she sees fit. As she defecates, make sure not to disrupt her pleasure. Inhale deeply, taking in the delightful aroma of her waste. Chew and swallow her excrement while continuing to clean her thoroughly with your tongue. As you penetrate deeper into her anus with your tongue, kindly thank her for allowing you this privilege and opportunity to clean her. Gratefully accept your role as her toilet slave, located beneath her ass.
