Brother's Strokes and Sister's Gaze: A Taboo Tickle

The creaking floorboard betrays their secret. A sister, caught in the act of pleasuring herself, quickly covers up as her brother enters the room. But his eyes have already seen the forbidden, his mind now filled with images of her naked form, her fingers glistening with her juices. He retreats, his hand finding his cock, stroking it to the thoughts of his sister, their shared secret now a bond neither can deny.
