Constant Arousal

Narcissa can’t move. It’s as if an invisible rope is binding her and an invisible gag is stuffed in her mouth. She looks wide-eyed and scared as Dobby walks around her and strokes his chin. He snaps his fingers.

Narcissa starts to grow horny, and her chest starts to heave.

"That's right, you're super aroused now, aren't you?"

Narcissa does not want to acknowledge Dobby.

"It's your new natural state," says Dobby. "You'll be horny every waking moment of your life, and nothing will satisfy you. You'll crave cock, and the more you get, the more you'll crave it."

"MMmmmpppph!" Narcissa is now super-horny.
