In the dim light of their shared bedroom, Michelle and her brother find solace in the forbidden. She guides his throbbing member into her eager mouth, swirling her tongue around the tip, tasting the salty pre-cum. He grips her hair, hips bucking as she takes him deeper, her eyes watering. She moans, the vibrations sending shivers down his spine. Their secret tryst is interrupted by a creaking floorboard, forcing them to quickly separate, breath ragged and hearts pounding.
