He was wrong though. Granger couldn’t even make it to the library. He caught a glimpse of her as she ducked into an alcove behind a tapestry. Casting a quick disillusionment charm on himself he also sent a little burst of wind at the tapestry to make it billow open as he slipped behind it to join her. Granger was sitting on the window sill, one heel tucked up by her arse and the other on the floor, her eyes closed and head tilted back. But the thing that took his breath away, was that Granger had one hand holding her knickers to the side, and the other was plunging one of her toys into her cunt, making wet sucking noises on each rhythmic stroke.
