Professor Sinestra

Making it to the room where he and Daphne meet up, Harry was questioning what he was going to be ordered to do. Daphne had laid out on the bed what looked to be a normal Gryffindor girl's uniform along with extra lacy pink bra and panties. Daphne spoke, "tomorrow you will report to Professor Sinestra's office for," here Daphne did air quotes with her hands, "detention. I expect you to act like a naught sissy girl and follow her orders for the night."

The next night, Harry arrived at Professor Sinestra’s office right after dinner. He knocked gently on the wooden door.

“Come in,” he heard from inside. Harry pushed the door open and gently closed it behind him. Professor Sinestra was seated behind her desk, her robes hung on the coat rack behind her.

“Good morning, Mister Potter," she said. She nodded at the chair across from her desk, “be seated.”

Harry shuffled across the small, crowded office. The walls were covered in astronomical charts, and each corner had a different type of ancient star-gazing device. One of the telescopes looked so old he wondered if Galileo might have built it.

He sat down in the chair across from Sinestra and gave the professor his full attention.

“Harry, I’m going to give you a choice. After last night’s debacle, I was going to give you a full week of detention, here in my office, cleaning up and copying my notes and other menial tasks.” She stood up and moved around the desk. She was wearing a tight, form-fitting dress, something more fitting for a cocktail party than teaching class, that was shockingly short. Harry noticed her heels, as well. Jet black and at least three inches. He wondered if the professor had been to a party after class had finished near midnight.

“But I don’t really have time to manage you, so I’ll give you a choice: four hours in my office each day for a week, or corporal punishment.”

“Corporal punishment?” Harry blurted out before he could stop himself, “that’s not approved…is it?”

“No, no it’s not,” she cocked her head to the side and gave Harry an apprising look. “But you’re a good student, and I know that spending almost half the day in my office is going to impact your grades. So, I’m offering you an alternative.”

Harry sighed. He knew exactly what Sinestra had in mind, and the professor was right: he really didn’t have time to spend all week cleaning her office. “Ok, let’s do that, then,” he sighed.

“Ok, stand up and take your robe off,” she ordered.

Harry did as he was bid, placing the robe over the chair he had just occupied. He was wearing the girls normal uniform under it.

“Ok, come over here,” Sinestra said, as she slid off the desk, and cleared off a space near the edge. When Harry was in front of her, the professor took him by the shoulders and turned him to the desk. “Elbows on the desk,” she commanded.

He bent over and placed his forearms on Sinestra’s desk. He gasped dramatically, and turned his head as he felt the professor raise his skirt and exposed his bottom, “Professor!”

“Pipe down, Harry. Eyes forward!”

“But—”

"SMACK."

“Oww!”

“I said, pipe down! Or it’s going to go worse for you,” the Professor claimed.

"SMACK."

“Mmmph,” Harry grunted as the Professor’s hand met his bottom and the buttplug in his ass again. The lacy knickers he was wearing offered little protection against Sinestra’s palm.

“Better,” Sinestra said, “much better.”

"SMACK."

“Mmmmnnnn,” Harry couldn’t believe he was getting spanked.

“Hmmm,” Sinestra said, “this really isn’t working for me.”

Harry opened his mouth to ask what the professor meant but decided against it. He didn’t want more punishment.

“Here, take your shoes and socks off, and put these on,” she ordered.

Harry straightened up and glanced down at where Sinestra was pointing. He saw that the professor had taken her heels off and was pointing at them. Not sure why he was doing it, he slipped his shoes off, and struggled into the heels. Suddenly he was three inches taller.

Sinestra nodded, “good. Now, resume the position.”

Harry turned back to the desk and bent over, his forearms snug against the wood grain. His ass was sticking up now, almost higher than his head. The professor lifted Harry’s skirt again, folding it over onto his back.

“There we go,” she said. “but there is one other thing we need to fix.”

Harry gasped as he felt Sinestra take hold of his knickers and begin to work them down over his ass and all the way down to his thighs, exposing his pale cheeks and plug to the room. “Professor!” he gave faux protest.

"SMACK."

“Enough talking, or you’re getting the punishment and the detention. Understood?”

Harry Potter, his bare ass lifted up on three-inch heels and exposed to the world, nodded meekly in submission.

“Good. Now we can proceed.”

"SMACK."

Harry gasped at the added shock of the professor’s open palm on his bare ass. He felt his panties slide to the floor, leaving his completely uncovered. He fervently hoped no one walked in on them.

"SMACK."

Harry tried not to make noise as the spanking continued, but he couldn’t help it. The blows were just hard enough to hurt but weren’t seriously painful. And then they stopped. Wondering if his humiliation was over, he started to turn and look at Sinestra.

“Nope, eyes forward, Potter,” she ordered.

Harry sighed, and braced for another smack on his bare bottom. Instead, he felt Sinestra’s hand began to lovingly stroke across his pale flesh. His eyes opened wide at the sensation. It felt incredible after the almost-painful spankings.

Sinestra moved her palm all across Harry’s bottom, soothing the skin, caressing his as a lover would. Sometimes he would gently tease the plug, pulling and letting it sink back into his ass. Every time she circled his cheeks, her hand slid closer and closer to Harry's womanhood.

To Harry’s surprise, he found himself getting aroused. His folds were instantly slick with his desire, and he began to, in a completely involuntary manner, move his ass towards the professor’s hand each time it came close to his wetness.

“Oh, not yet, dear. Not yet,” she commented.

"SMACK."

Harry gasped, loudly, as Sinestra’s palm met his pale flesh again. It was unexpected, and harder than before. He braced for another blow, but it never came. Instead the professor went back to the loving caress, running her smooth palm over Harry’s pale cheeks. Pale cheeks that were starting to turn pink from the repeated blows.

Harry found himself holding back a moan as control of his body seemed to be slowly taken away from him. His hips kept rotating his ass towards the professor’s hands, desperately wanting to feel the gentle caresses move to the folds of his labia.

"SMACK."

Harry gasped, even louder this time. That one had hurt. He had figured out the game, though, and understood what was happening. Each spank would be complemented by the loving caress.

The discipline continued on for several more minutes this way, smacks of his bare ass followed by loving caresses, caresses that never quite touched his womanhood. After all of his frustrations the last few days, followed by the casual humiliation and arousal at Sinestra’s hands, it was more than he could handle. His hips were now gyrating in an attempt to bring her folds in contact with Sinestra’s palm between each spank, and Harry was almost on the verge of tears.

Finally, he whispered, “please.”

“What was that, dear?” the Professor asked softly.

“Please,” he whispered again, a little louder.

“Please what, dear?” she said again.

“Please…touch me,” he almost sobbed the words out.

“Where, dear?” Sinestra questioned.

“My… my vagina,” Harry said finally.

“Oh, what an ugly, scientific word for something so beautiful. Try something else,” she added.

Harry paused a second. He wasn’t used to cursing, but he was pretty sure what word Sinestra was looking for. His legs were starting to tremble from the tension.

“Please… please touch my pussy,” he breathed.

“You ask so prettily,” Sinestra said, and slid her hand over Harry's folds, completely engulfing them.

Harry moaned loudly, and thrust his hips back, as much as he could, to meet the professor’s questing digits.

“Oh my, someone is quite wet,” she commented, “someone seems to be enjoying their discipline.”

“Yes, professor,” he could barely get the words out between his moans. He could not remember ever being this aroused, even when he had been fucked. He suddenly remembered how Narcissa's pussy had tasted as she shot her cum into his mouth and moaned even louder.

“Would you like me to stop?” Sinestra taunted.

“No! Please don’t stop,” Harry begged.

"SMACK." The spank caught him by surprise, mid-moan, and the corresponding yelp he let out was quite loud.

“Mister Potter, you are full of surprises,” Sinestra commented, as she resumed stroking her student’s muff.

“Yes, Professor,” Harry commented.

Sinestra began to rub her thumb across Harry’s plug again, gently stroking it while continuing to massage the folds of her labia.

Harry was lying flat on the desk now, gripping the sides with both hands, holding on for dear life. As Sinestra’s thumb began to gently touch his plug, Harry felt it. He finally, finally felt.

“Professor!” he breathed, focusing on the digit that was stroking the plug in his asshole, at the wonderful sensation it created. It began to build, the feeling that he knew must be right, deep in the very center of his being. The entire lower half of his body was trembling from the sensation as it radiated outward, washing over every square inch of him.

“Professor!” he managed to get out, one last time, as the waves began to crash over him, over and over. He thrust his pussy hard against Sinestra’s hand, desiring as much contact as he could get, reveling in the sensations it created.

“Oh! Oh! Oh God, Oh Fuck, Oh Fuck, I’m com…I’m com…innnnggggggggggg…” The sensations of the orgasm were so powerful that Harry thought he was going to faint. Nothing else in the world mattered, other than Sinestra’s hand.

As the waves crested, and his mind emptied, he was filled with a sensation of utter peace and belonging in and rightness. It was the most amazing thing he had ever felt. And the waves of pleasure began to diminish, his legs trembling, Harry found himself almost sobbing in relief. And now he understood. He understood what a real orgasm was like.

He laid still for a good minute or two as Sinestra resumed stroking his ass, the sensations quite pleasing after his orgasm. Finally, Harry straightened up, his skirt falling down and covering his bare ass, kicked the panties off the heels he still wore, teetered over and collapsed in the chair.

He glanced up at the professor, who was appraising him with a knowing glance.

“Harry, would you lift your skirt, please?”

Puzzled, but exhausted and in a wonderful state of languor, he raised her skirt, showing the professor his pussy.

“Mister Potter, can I give you some advice?”

“Of course,” Harry replied.

“You have a really cute little muff there,” Sinestra remarked, “the boys and girls will start taking a liking to yours one of these days.”
