In the quiet of their shared room, the teen siblings find themselves drawn together by a mutual, unspoken desire. She watches him watching porn, his cock tenting his pants. He notices her gaze, her cheeks flushed, lips parted. Their eyes meet, and the air grows thick with tension. They succumb to their forbidden curiosity, their exploration tentative yet passionate. His hands trace her curves, hers wrap around his cock, their first tastes of each other sweet and intoxicating.
