A lonely boy, left home alone, can't resist the allure of his sisters' unwashed panties. He buries his face in the soft, worn fabric, inhaling their intoxicating scent. His heart races as he imagines their lithe bodies moving against the cotton, the friction creating a unique, tantalizing aroma. He rubs his cock, lost in his fantasy, until he finds his release, staining the panties with his forbidden essence. He hides them, guilty but satisfied, until the next time his sisters leave him alone with their intimate lingerie.
