Groggy from sleep, the young stepsister finds her stepbrother's eager face looming over her. His hands, already exploring her curves, awaken her in more ways than one. She squirms, half-angry, half-aroused, as he lifts her nightie to reveal her bare pussy. He teases her clit, making her gasp, before pushing a finger inside her, feeling her tight, wet heat. She responds, her body betraying her initial protests, as they begin a taboo dance of desire.
