Lucius rapped on the door of the Black house. He was greeted by Bellatrix, who informed him Narcissa would be down in a few moments; she was still getting ready.
More than a little annoyed he strode away from the front door which had been promptly shut in his face. He took steps around the neat garden, treading on the grass, to pass the time.
There was a sudden stream of light from the house that lit up the lawn and he turned to face the building, expecting the door to be open and Narcissa to be standing there ready to go.
She was not.
The light, however, had come from an upstairs window and as Lucius squinted up at in the dark a figure emerged between a slight gap in the curtains, casting a vague silhouette in the bright light. He frowned deeply, wondering who the figure was. She was definitely female, he could tell that much, from the curves and dips of her body.
Several things happened very quickly.
The figure in the window turned to face the lawn and light was finally cast upon her. Narcissa was revealed.
Clad in very little.
There was a scream and she scrambled away from the window but Lucius remained still, his expression a contorted mixture of shock, pleasure and amusement.
There were shouts and the door was blasted open. Bellatrix stood there, wand pointed at him and sent a Stunning Spell at his chest.
He flew backwards, landing in a twisted heap on the moist grass.
Lucius showed no signs of recognition that he had been stunned. He felt a twinge in his pants and he just grinned at himself in the darkness.
Nor did he show any signs of recognition when Bellatrix kicked him and called him a pervert.
