In the dimly lit room, Carlos Simoes and his step-sister Fran, both restless and horny, succumb to their taboo desires. Fran, her heart pounding, tentatively reaches for Carlos' stiff cock, her fingers wrapping around its thickness. Carlos, his breath hitching, guides her hand, showing her how to stroke him. Their eyes lock, the air thick with tension, before Fran leans in, her tongue tentatively tasting Carlos' salty pre-cum. Carlos groans, his hands finding Fran's hair, guiding her as she takes him deeper. Their bodies press together, their moans echoing in the silent room, as they give in to their forbidden passion, each thrust bringing them closer to the edge.
