In the dim light of dawn, a thick, veiny cock stirs to life, tenting the sheets. A sister, roused by her brother's morning wood, can't resist the temptation. She inches closer, her eyes locked onto his massive, throbbing manhood. He awakens with a start, but she's already taken him into her warm, wet mouth, sucking eagerly. He grips her hair, guiding her as she takes him deeper, her throat convulsing around his length. She moans, her pussy dripping with lust, craving his release.
