2T4U/Bandit in the park/Call out and get their attention
"Hey, what do you think you are doing?" Your booming voice splits the night and causes the older girl to gasp and jump to look around behind her. This move does not, however, cause her to cease urinating on her sister's face. In fact, the relaxing of her predatory position actually causes the stream to move higher to land directly on the bridge of the younger sibling's nose to witch she responds by sitting up and burying her face quite steadily in her older sister's crotch as the remainder of the urine dribbles down her chin.
The older one, Raquel, looks like a deer caught in the headlights as she looks over at the approaching stranger as her stream dies to a stop and her little sister lies back and starts coughing and gagging. "Uh, no! This is..." Raquel babbles out as she quickly steps a leg off of her little sister.
"She peed all over me!" The younger one demands in a furious tone.
