In a cramped, dimly lit closet, a pair of tiny siblings, barely out of their teens, find themselves in a taboo embrace. The girl, her panties soaked in piss, guides her brother's thick cock to her lips, hungrily licking the mixture of her own urine and his pre-cum. She's a tiny thing, but her lust is immense. Her brother, equally turned on, watches her tiny hand stroke his cock, eager for her to take it all in.
