Brazilian siblings, Carlos and Fran, find themselves in a tense living situation. Fran, a gorgeous, curvaceous novinha, struts around the house, her hips swaying seductively in tiny shorts. Carlos, her brother, struggles to maintain his composure, his cock twitching at the sight of her. One day, Fran decides to give Carlos a show, sitting on his lap and grinding her ass against his crotch. Carlos, unable to resist, grabs her hips and thrusts, feeling her warmth through their clothes. Fran moans softly, loving the attention, but a sudden noise makes them jump apart, leaving them both breathless and yearning for more.
