When Pansy went to the great hall for breakfast Harry was not there. She sat at the Slytherin table with Draco and Hermione, and kept shooting gazes at the entrance of the hall. The other two exchanged looks.

"Everything alright Pans?" Draco shook her from her daydream.

"What? Oh, yeah, is just Harry…" she trailed off

Hermione pushed

"What? Are you guys alright?"

Pansy giggled

"Well something happened yesterday and long story short he said he was going to torture me today. So, I'm kind of…edgy."

Draco and Hermione laughed. She decided to tell them about the Hufflepuff girls in the bathroom. She still felt like she could use some reassurance. Hermione hugged her.

"They are just jealous. My nemesis are the death eater fans; those are real nut jobs. We are targets because we got the hottest guys in school. Is a tough life Pans."

Pansy smiled and hugged her back.

Hermione shot a daring look towards the Hufflepuff table while holding her friend. She fought a war to end discrimination, they didn't need this crap.

Finally, Harry arrived at the great hall but he walked straight to the Gryffindor table and sat next to Ron, facing the Slytherin table. Pansy tensed up. After a few minutes, a piece of parchment appeared in front of her.

Take off your panties

She blushed deep red and looked up to the Gryffindor table. Harry lifted a challenging eyebrow.
Her hands were shaking and she thought about running to the bathroom. The parchment spelled

Take them off here. Now.

She took a deep breath. Think, Pansy, think. The hardest part is getting them down to your thighs. She decided to ask for help.
She stood and sat again, so her robes were like a tent around her and her skirt flapped, so now her butt was on the bench. She moved her skirt up under her robe and pinched her panties with the robe fabric. Then she asked Hermione in a whisper

"Can you pinch this fabric, please? All of it?"

Hermione looked confused but did it. Pansy suddenly stood up, her panties pinched down by Hermione. That put them under her butt. It would get easier from here. She sat again.
Hermione whispered in her ear

"Did I just help you take off your panties?"

"Shut up! shut up! shut up!"

Hermione burst out laughing so loud that Pansy used the distraction to finish pulling them all the way down her legs and then off.
The two girls kept giggling and whispering while Pansy kept the panties underneath the table, folded them and then rolled them until they fit in her hand. Lucky, they were a thin blue lace. She felt really horny now.

When breakfast was over she walked out with Hermione and Draco. They stood on the hallway, waiting for Harry.
Harry approached them, patted Draco on the back, kissed Hermione on the cheek and with a quick seeker move took the panties from Pansy's hand. Then he walked away, only turning to give her a malicious wink.

"That bastard really thinks he can torture me. Oh, it's on Potter."

And with that, she walked away.

Draco looked confused.
"What was that?"

Hermione laughed and whispered in his ear all the dirty details of the panties' incident.
Draco froze

"So my girlfriend just pulled down my ex-girlfriend's panties. In the great hall; in front of everyone."

"Yup"

"I need to go to the bathroom. Or a closet. Room of requirement. Whatever. I need to wank off this before class."

Hermione smirked and took his hand
"Let's go to Moaning Myrtle's bathroom"

They ran down the hallway and into the bathroom. Myrtle was not there, thank Merlin. They got into a stall and she fell on her knees, undoing his trousers, then took him in her mouth. He leaned against the cubicle wall, head rolled back, grabbing her hair and pushing her deeper.

"Yes, suck my cock, you dirty girl. Naughty girl, playing with other girl's panties."

Hermione gave him an innocent look from down there, making him even more ravenous. He pulled her up and turned her around. He lifted her skirt and laced his fingers on her panties.

"Is this what you did to that girl? -he said pulling them down slowly- you left her arse bare and her pussy exposed like this?"

She breathed "Yes".

He spanked both of her cheeks, hard. She squealed but loved it. He did it again.

"You need to learn your lesson. You need to learn what happens when you play naughty with other girls."

He positioned himself behind her and rammed his cock inside all the way in, then went on a frenzy, pounding like a madman. She loved it, moaning and yelling. They came hard, then quickly put themselves together and ran to class.

They walked late into the potions lab, but being the best of the best has its advantages, especially with Slughorn. When they settled on their desk he asked

"Did you silence the bathroom?"

'No, didn't you?"

"Nup"

"Too late now."

They both covered their chuckles with their hands.

In the meantime, Pansy was on her table with Ginny, but she kept stealing glances at Harry. He faked indifference for the first few minutes. Then she looked back and he was sitting with his elbows on the desk, his hands in front of his nose. He spread his pinky and ring fingers and she saw the hint of blue in his hands. He literally had her panties on his face. In class. She opened her eyes like saucers. He gave her a challenging look. She turned to the front of the room, blushing, wetness pooling between her thighs.

When the class was over Harry ran out and disappeared. Then for the next class, he walked into the room last. He took the empty seat next to Pansy on the last row, but sat on the edge of the bench and didn't look at her. She took a breath and sat primly.

Halfway through the boring History of Magic lecture, she saw that he had the panties on the hand he was resting his face on. When he caught her eye, he looked down. She followed his gaze. His other hand was on his lap, and he was tracing circles with one finger on an obvious tent that he had in his pants. The Boy Who Lived, the Chosen One, the Savior of the Wizarding World was actually fondling himself in class.

Pansy felt like she was going to explode. Her thighs were soaked and this crazy bastard was smirking at her like a nut. He was going to pay dearly. He was going to regret the day he challenged Pansy Parkinson.

He performed his disappearance act all through the day in between classes and at lunch time, keeping her on edge. During Charms, when they had to do some practice he paired with Draco, whom by now was all in on the torture game, and was toying with his girlfriend too; whenever Pansy looked that way Harry did something vulgar, like stroking his wand or making lascivious gestures with his tongue. Draco would laugh his arse off and even give him suggestions, encouraging the outrageous behavior. Pansy was furious and hornier than ever.

The last class was transfiguration and by now she was fed up. He was once again sitting on the opposite edge of their bench, and when she looked at him he held his fingers in front of his mouth in a V and then slither his tongue through them. That was it. She had enough.

She took her pure gold quill and showed it to him in challenge. Then she performed a cleaning spell and when he looked again at her she licked it. He froze. Then holding his gaze, she brought it under the table and slid it under her skirt in between her legs. She bit her lower lip in pleasure. He gaped. She left the quill there and lifted her arms to stretch in her seat, wiggling her hips suggestively and then rested her face in her hands while making very small riding motions in her chair. She looked at him and gesture for him to close his mouth. He stared at her for the rest of the class. She smirked. Don't try to outmaneuver a Slytherin.

At dinner, the two couples sat on the Slytherin table, girls on one side, guys on the other, sharing the naughty details of the day.

"Maybe he needs a good, final piece of torture. Actually, so does Draco, he had the nerve to punish me for taking your panties off today, and then he got in with Harry on the obscenity train during Charms and Transfiguration."

Pansy smiled maliciously

"Any ideas"

"Indeed"

The girls walked together, arms laced, giggling and whispering all the way to Gryffindor tower, the boys trailing behind like lost puppies. When they arrived, the common room was empty. Perfect.

Pansy took a sit in an armchair, pulling her skirt halfway up her thighs.
Hermione stood in front of her, then bent forward, put her hands on Pansy's knees and slowly spread them; then kneeled on the chair between her legs and cupped her face, and gave her a lustful kiss. Pansy responded in kind. The boys' jaws were hanging so low they might fall off. Pansy slowly ran her hands up Hermione's thighs, under her uniform skirt, until she reached her panties. Then she slowly pulled them down inch by inch. When she reached the knees, Hermione stood up and let her pull them all the way down, until she got her feet off them. Pansy folded the delicate silk and offered them to Draco, who looked utterly shocked.
Hermione gave her one last lascivious kiss.

"Thank you. You are such a great friend."

Then walked toward her room and turned to look at her boyfriend.
"Malfoy, are you coming or not?"

Draco snapped out and before going up the stairs turned around to look at Pansy, hands in prayer
"Thank you!"

And with that, he ran up the stairs.

Pansy turned to face Harry, eyebrow lifted in challenge. He fell on his knees in front of her.

"You win. I give up. I surrender. Pansy Parkinson, I'm begging you. Let me make love to you."

She smirked and stood up, slowly walking towards his room. Then she turned

"Are you coming or not?"
