In the dimly lit hallway, the sister, dressed in a sheer nightgown, feels her brother's gaze on her. She leads him to her room, their hearts pounding with anticipation. He strips her, revealing her ripe, eager body, and buries his face in her pussy, lapping at her juices. She moans, guiding his cock into her tight hole, riding him until they both shatter in a climax of taboo ecstasy.
