"Now, watch closely," the professor said, his voice dropping to a conspiratorial whisper. He lowered his head, bringing his face closer to her exposed sex. "This is the expulsion point." And with that, his thumb pressed firmly against her swollen clit, and his index finger began to rub the sensitive nub in a quick, expert rhythm.

Ginny's entire body went rigid. A high-pitched keen escaped her throat. "No, no, no, no, nooooo!" she chanted, but her hips began to buck involuntarily against Ron and the professor's hands. Harry, following the professor's lead, increased the pressure on her nipples, twisting them slightly. The dual sensations were overwhelming.

"The spirit is fighting! Don't let up!" the professor ordered. His fingers worked faster, plunging slightly into her dripping entrance before returning to torment her clit. "Mr. Weasley, knead the flesh in your hands. We need to stimulate every nerve ending!"

Ron, his eyes just barely peeking at the view of his splayed sister with her legs in the air, began to clumsily massage her ass cheeks. The combination of stimuli—Harry's pinching fingers on her nipples, Ron's gripping hands on her bottom, and the professor's relentless, skillful manipulation of her clit—was too much. Ginny's mind went blank, overwhelmed by a tsunami of shame and a terrifying, rising tide of pleasure.

"It's... it's... aaaaaah!" she screamed, her body convulsing. Her back arched violently off the floor, her legs shaking uncontrollably. A powerful orgasm ripped through her, far more intense than anything she had ever felt before. Wave after wave of humiliating pleasure crashed over her as the three of them held her down and **** it from her body. She could feel herself gushing against the professor's hand, her fluids coating his fingers as her inner walls clenched and spasmed.

The professor kept his fingers working her through the entire orgasm, milking every last spasm from her body until she collapsed, limp and sobbing, onto the floor. "There," he said, his voice returning to its normal calm tone as he finally withdrew his hand. "The spirit has been fully expelled. The procedure is complete."

He stood up, wiping his glistening fingers on his trousers as if her feminine fluids were merely ink. Harry and Ron held on to Ginny's exhausted, naked form as if she would die if they let go. The professor retrieved his robes and gently draped them over her, covering her from view.

"Rest is essential now," he said, his demeanor once again that of a kindly academic. "She'll be drained. You've both done a commendable job. It was a difficult lesson, but you learned it well."

He turned and walked toward the door, leaving Harry and Ron kneeling beside the covered, trembling girl.

They stood there for a moment, trying to process everything.

"What just happened?" Ron finally asked, his voice barely a whisper.

"I... I think we saved her," Harry said uncertainly. "But I've never heard of that kind of magic before."

"Me neither," Ron admitted. "And I've never seen a professor dressed like that. Who do you think he was? One of the new ones?"

Harry shook his head. "I have no idea. But he seemed to know what he was doing."

Ginny stirred beneath the robes, letting out a soft whimper. Harry knelt beside her, pulling the robes more tightly around her.

"It's okay, Ginny," he said softly. "You're safe now."

Ginny's eyes fluttered open, looking at Harry with an expression of profound embarrassment and something else - something that looked like gratitude. She buried her face in the robes, her body trembling slightly.

Ron stood awkwardly to the side, still trying to make sense of what had happened. "Do you think we should tell someone about this?"

Harry looked at the door where the mysterious professor had disappeared. "I don't know. Who would believe us?"

As they helped Ginny to her feet, supporting her between them, they couldn't help but wonder about the strange professor who had appeared out of nowhere and taught them a lesson they would never forget - a lesson that seemed to be about defense against deeply imbedded magic, but felt like something else entirely.
