Caught in the act, they argue, but the tension only escalates their arousal. Soon, they're facing each other, naked, their bodies aching for release. Michelle's eyes widen as she takes in her brother's thick, straight cock, imagining it buried deep inside her. Just as they're about to cross the final line, an unexpected intrusion forces them to abort their taboo encounter.
