After a heated argument, siblings find themselves alone in the house, their anger replaced by a tense, unspoken attraction. The brother, his cock tenting his pants, watches his sister's ass sway as she walks away. She feels his gaze, her pussy throbbing with desire. They retreat to their rooms, masturbating furiously, their moans echoing through the halls. Later, they collide in the kitchen, their bodies pressing together. She feels his hard-on, he smells her arousal. They hesitate, then succumb, kissing passionately as they grope each other, their clothes shedding quickly.
