Mariana's eyes widen as she spots Rico's massive erection tenting his pants. She licks her lips, her pussy throbbing with need. She knows she should stop, but the sight of his huge cock is too much to resist. She slowly pulls down her panties, exposing her wet slit to Rico. He groans, his cock pulsing with desire. Mariana reaches out, her hand wrapping around his thick shaft. She strokes him, her thumb rubbing against the pre-cum leaking from his tip. Rico can't hold back any longer, and with a grunt, he releases his load, his hot cum splashing onto Mariana's stomach. She smiles, her pussy aching with unfulfilled desire.
