Daisy Potter, Dobby's Ball-Drainer

Dobby the House Elf wanted to make sure Greatest Witch Ever Daisy Potter didn't return to Hogwarts. First, he blocked mail being sent out, then blocked mail being sent in. He befuddled Owls and Spells. But on the morning of Daisy Potter's eighteenth birthday, he decided on a new method.

Daisy had been admiring herself. She was so fucking hawt!

With her curly red hair, her heavily freckled skin, beautiful green eyes, hefty GG-Cup melons and big bubble butt, she couldn't wait to go to school and fuck.

It was while fondling herself in the mirror that she felt a presence. It had pressed itself right up against her arse and after a small turn found a small, humanoid creature with his face buried in her arse.

She had no chance to ask any questions because he was sending her crashing into a dozen orgasms from licking out her arse.

The pleasure proved too much and the Witch's knees buckled. Face down, arse up, Daisy was presenting an easy target for Dobby, who was enjoying being in control of the Saviour of the World.
