Plugged Harley with her wand

As the assistant finished dressing Harry, Bellatrix's eyes sparkled with sadistic pleasure. She reached out and gently adjusted the pink satin dress, making sure it was perfectly in place. Harry's face burned with shame as he felt her touch, his eyes fixed on the floor in humiliation.

"Perfect," Bellatrix cooed, stepping back to admire her handiwork. "Now, let's add the final touch." She reached out and took Harry's wand, the one she had forced him to use earlier. With a cruel smile, she began to slowly insert the wand into Harry's anus, the wood feeling cold and unforgiving as it slid inside.
