My sister has the most irresistible ass I've ever seen. It's round, firm, and always begging for attention. When she wears her mini skirt, it barely covers her curves, driving me wild with desire. I can't resist the urge to grab her, to feel her soft skin against mine, to taste her sweetness. And when she bends over, her skirt riding up her thighs, it's too much to handle. I find myself unable to resist, my mouth watering as I reach out to taste her. She doesn't object, in fact, she encourages me, her moans filling the room as I explore her with my tongue. The sensation is overwhelming, her taste intoxicating. I can't help but take her completely, my throbbing member finding its home between her luscious cheeks. The ride is intense, our bodies moving in rhythm, our moans echoing until we reach our climax.
