As the Metro's Virgin Patrol intensifies, so does the heat between these innocent siblings. The sister, her eyes wide with wonder and desire, takes the lead, guiding her brother's hands to her budding breasts. He tentatively cups them, feeling their weight and softness, while she moans softly, her body arching into his touch. She then reaches down, tentatively stroking his hard cock through his pants, her touch sending shivers down his spine. Their exploration turns more intense as they strip each other bare, their bodies pressing together, their breaths coming in ragged gasps. The sister, her virgin pussy dripping with desire, guides her brother's cock to her entrance, and with a gentle thrust, they cross the threshold into adulthood and taboo pleasure.
