Cate Harrington, the curious college coed, finds her brother alone in his room. She's heard the rumors about his impressive size and wants to see for herself. With a playful smile, she asks him to show her what he's got. He's hesitant at first, but her pleading eyes convince him. Slowly, he unzips his pants, revealing his throbbing cock. Cate's eyes widen in delight as she watches him stroke it, her own pussy growing wet with desire.
