The Silver Knickers

Harry Potter walked across the grounds of Hogwarts, trying desperately to quell the beginnings of an erection. It was just not on for the Head Auror to be walking around at half mast. But absolutely nothing he did, nothing he thought of was making it go away. And worse, with every step towards the school it was threatening to make a further appearance, something his tailored Auror robes wouldn’t hide for a second.

He took a deep breath and thought about the forty-seven uses for doxy urine. That ought to keep him presentable until he could find – no, he’d better not think about that, he had better stick to thoughts of urine.

His reason for visiting Hogwarts was perfectly legitimate. He needed to meet with the Headmaster about the security needed for the twenty-fifth anniversary of the re-opening of Hogwarts. His reason for arriving two hours early was not so innocent. They had shared only one night, one dirty, late-night rendezvous and Harry had put out that fire before it had caught. But it had been seven weeks and Harry’s memory of that night – those touches – haunted his every waking moment.

No one blinked when he’d insisted on handling Headmaster McMurrough's request personally.

Harry waved at Neville as he passed by the greenhouse. A quick peek told him that very few students – and certainly not the one he longed for a glimpse of – had arrived at Herbology. They must be still at breakfast. Harry made his way towards the Great Hall. Luck was with him as he noticed Al in a hallway just off the entrance to the dungeons.

He was standing with a tall Slytherin girl, their backs to Harry. They each had parchments up against the stone wall and were furiously writing. Al and (Harry assumed) his new girlfriend looked to be frantically trying to scribble the last few inches of an assignment due this morning.

“Hi, Al,” Harry greeted the couple as he approached.

Al turned and gave a huge smile –“Hey, Dad!”– then gave a quick glance at the girl and burst out laughing.

The blond girl dropped her parchment, but made no other move. She looked frozen in place.

“Al,” Harry chastised. A lot of people overreacted when meeting Harry, but it wasn’t right to make someone feel embarrassed over their nervousness.

Then the girl turned around and kohl-rimmed, grey eyes met Harry’s. No number of uses for doxy urine could help him now.

Standing there – in a girl’s Slytherin uniform: too short skirt, too tight blouse, and a Slytherin tie – was Scorpius Malfoy.

Harry’s jaw dropped and it felt like every ounce of blood in his body flowed to his cock. Speechless, Harry took a minute to let the vision before him sink in. His eyes fell to the high-heeled sandals, then up the smooth, naked, incredibly long legs. The thin, white blouse pulled taut across Scorpius’s broad shoulders, buttons ready to pop any moment. Merlin, Harry was sure he was going to have a heart attack. Or possibly an orgasm.

But his son was standing two feet from him, so he pulled himself together the best he could.

“Scorpius.” Harry nodded to the boy as if this was everyday stuff. And was that lipstick? Fuck.

“Mr. Potter.” Scorpius’s cheeks and neck bloomed red, his eyes flickering to Harry’s crotch.

Harry’s cock strained against his robes, as if it were trying to get closer to its target. Harry wasn’t surprised he had run into Scorpius, really this was exactly why he’d come here: for this meeting, for this reaction from his body, to see Scorpius blush. Because he needed to prove to himself that those memories were real and not the fevered imaginings of a dirty old man. Then to find Scorpius like this…

“Interesting choice of apparel this morning,” Harry said, a slight tremble to his voice.

Al bent over double, howling with delight at his friend’s embarrassment.

Harry took the moment to cast a wandless Notice-me-not on his crotch. This erection wasn’t going anywhere, except maybe Scorpius’s painted mouth. God, he had to get rid of Al. Immediately.

“Al, don’t you have Herbology?”

That stopped the snickers, quick.

“Er, yeah.” Al looked at the parchment still in his hand.

Scorpius bent down to pick up his dropped assignment and Harry’s heart skipped a beat.

“You are not going to class dressed like that.” He likely sounded a bit more upset than appropriate, but he hoped he simply came across as a concerned father figure and not a jealous lover who was seconds away from throwing Scorpius over his knee.

Ignoring Harry, Scorpius turned to Al. “Look, Al, I think I’ve fulfilled the ‘embarrassment beyond all possible imaginings’ part of the deal. Can I get changed now?”

Al contemplated this for moment. “Well, you were a good sport about it and the whole school did get a great laugh at breakfast. And your face when you heard my dad’s voice…”– more hysterical laughing – “I’ll treasure that memory forever.”

“Is this a bet of some sort, boys?” Harry’s eyes narrowed. The idea that the whole school had seen Scorpius like this…

Harry fought the urge to grab him and hide him away somewhere.

“Just a dare, Dad. Nothing bad.”– Al turned back to Scorpius –“Look you can get changed, but you’ll be late for Herbology.”

Scorpius did not look at all disappointed about that.

“Al, just tell Nev I had to talk to Scorpius to deliver a message from his dad and he’ll be late. It really isn’t appropriate for Scorpius to walk into class like this.” Through a clenched jaw, Harry added, “Poor Professor Longbottom would be rather disconcerted.”

Al thought again, eyeing Scorpius up and down and then bursting out in giggles again. “Alright,” he nodded, “you’re off the hook. Dad, you going to be around at lunch?”

“Hopefully, if I can get finished with Headmaster McMurrough in time.”

Al nodded. “Great, I’ll catch you later.”

As Al dashed off to class and out of sight, Harry turned towards Scorpius, his eyes fierce and possessive.

“I’m going to Disillusion you,” he said, his voice eerily calm. “I don’t want another soul laying eyes on you while you’re wearing that.”

With a swipe of his wand he Disillusioned them both. He grabbed Scorpius’s hand and pulled him towards the stairs. “Not a word.”

Quickly and quietly they made their way to the third floor and found an empty classroom. The floor, chairs, and desk were covered by a thin layer of dust. Harry carefully shut the door and pulled his wand to ward and silence the room. Anyone who came within 20 meters of the door would suddenly feel compelled to race to the first floor loo.

Only then did he whisper, “Finite Incantantem.”

As Scorpius’s nervous kohl-enhanced eyes came into view, Harry growled and pounced.

They had agreed – Harry had persuaded Scorpius to agree – it would never work between them. They were attracted to each other, Harry conceded but Harry’s children, his career, his social standing would all be put in jeopardy by any relationship with Scorpius. Harry had everything to lose and he’d convinced himself that sex with a teenager was simply selfish. Everyone would get hurt. Even Scorpius, though he didn’t see it that way.

It wasn’t right for Scorpius to spend his time pining for a man more than twice his age, one that he couldn’t be seen with, couldn’t write to or talk to without huge risk, couldn’t even talk to his friends about. It wasn’t fair. However, at this moment, Harry believed that was possibly the worst decision he’d ever made.

The talk happened the morning after Scorpius’s birthday party and Harry hadn’t seen him since.

He captured Scorpius’s hands and pinned them to the door. Their bodies molded together as they devoured each other’s mouths. Scorpius’s erection thrust against Harry’s hip bone and Harry broke their kiss with a gasp.

Scorpius’s pink lipstick had smeared across the top of his lip and his cheek. Harry thumbed over the smudge making it worse rather than better. Scorpius smirked beneath Harry’s finger.

Harry’s eyes fluttered closed as he tried to get control of himself. “Scorpius, you will be the death of me.” Scorpius chuckled at Harry’s husky tone.

“You like the outfit, sir?” Scorpius pushed Harry back so he could better display his skirt. Scorpius lifted the skirt a fraction and curtsied, ever the well-mannered aristocrat.

“Fucking hell, Scorpius. You are trying to kill me!” Harry pressed his palm hard against his trapped erection, trying to relieve the pressure. Auror robes were unforgiving at times like this.

Scorpius, unconcerned with Harry’s discomfort, twirled around, letting the short skirt rise slightly in the air. Harry caught the slightest glimpse of silver lace knickers.

With an exasperated groan, Harry demanded. “Would you please tell me why you are out in public like this?” For whom are you dressed like this? Scorpius had walked into the Great Hall, during a crowded breakfast, dressed like this. The slightest movement made the skirt rise and fall; a little breeze and Scorpius’s arse would have been on display for every randy teenager at Hogwarts to steal a peek at.

Harry’s lust began to edge toward fury. He knew he had no right, no claim on Scorpius but the burning jealousy was consuming him.

“It was like Al said, it was a dare.” Scorpius bit his lip and looked at the floor; his sandals traced a line in the dust covered floor.

“And you took the dare because?” Harry’s voice was low, dangerous.

Scorpius raised his eyes to Harry, and debated on how to respond. He looked uncharacteristically vulnerable, like that first time, entirely unsure of Harry’s reaction. “I needed to do the dare because I couldn’t tell the truth.”

A line creased between Harry’s eyebrows as he started to guess what had happened.

“We were all playing a game of Truth or Dare, the first time since… the first time since my birthday. It hadn’t occurred to me that anyone would ask about,” Scorpius’s gaze focused above Harry’s right shoulder. His obvious insecurity pulled Harry forward. He grasped Scorpius’s hand and gave it a reassuring squeeze. I didn’t think they’d ask about anything important.”

“But they did.”

“Al must have guessed there was someone…” Scorpius looked at him then with a sad smile. When Harry just nodded in understanding, he cleared his throat and continued, “anyway, as soon as I said Truth, he jumped at the opportunity to ask who I … who I fancied.”

Harry took a step backwards, without realizing it.

“I’m sorry.” Scorpius whispered. His voice cracked as he whispered, “I’ll be more careful–”

Harry couldn’t take it, the gut-wrenching fear in those words. Albus had sounded that way when James convinced him he wouldn’t be allowed to go to Hogwarts because he spilled Gramma Molly’s hair colouring potion on the carpet.

Harry retook his place in front of Scorpius and kissed him gently, unable to stay away. He was cruel, maybe to both of them, giving in to such temptation but standing this close to Scorpius and not touching him, not kissing him, was impossible.

“What happened then?” Harry asked softly. “The game wasn’t magically binding or your dad would have my bollocks for billiard balls by now.” He forced his tone to be light and added, “and you wouldn’t be wearing this charming outfit.”

Scorpius managed a broken smile. Harry’s heart ached seeing it.

“It was magically binding; we are Slytherins. But too many families have their important secrets. We always use a fail-safe clause.”

“The dare.”

“The dare. Since I opted out of answering truthfully, Al got to pick any dare and I had to comply. He let me off pretty easily, considering.”

“You did this for me?” Harry’s heart pounded in his ears; his wilting erection surged back to life.

Scorpius gave a weak smile. Once bitten, Harry realised. Scorpius was waiting for Harry to push him away again, to make that night in July nothing more than a bitter sweet memory of his first time. And now Harry wondered how he’d ever walked away from Scorpius. How could he have told those lies: it’s over, it’s not worth it? And Harry knew exactly what Scorpius had heard: You are not worth it.

Harry hated that he couldn’t find the words to reassure him. He’d always been pants at such things.

Scorpius stared down at the floor, eyes shining. “Are you mad?” he whispered, as if he didn’t want to know the answer.

“I’m not mad. I think,” –Harry paused to run a hand through his hair, giving himself time to find the right words– “I think we need to be more careful in future.”

Scorpius snapped his head up to look at Harry.

Harry’s hands gently cupped Scorpius’s chin. He leaned forward and pressed a hard, possessive kiss onto Scorpius’s lips. “Until you are out of school, at least. We’ll need to be very careful.” Harry spoke breathlessly into Scorpius lips, barely breaking the kiss. Harry was amazed at how easy those words were to speak. In July they seemed ridiculous.

Harry felt Scorpius’s lips break into a huge grin a second before he was mauled with all the enthusiasm of youth. Scorpius hands were everywhere, clawing at the complicated clasps of the Auror robes, tugging on Harry’s hair, trying to devour every inch of him he could reach.

“I thought…” Scorpius choked out between kisses. “I thought you would–”

“Hush, it’s ok. I know what you thought.” Harry kissed along his jaw, nipped his ear and whispered, “How could I possibly walk away from you?”

They kissed again, desperate and messy. Harry tried to pour everything he couldn’t voice into it, all the passion and want and absolute need. Harry rubbed Scorpius’s back tenderly then suddenly stopped when his hands ran across something unexpected. Scorpius went rigid as Harry’s hand traced the outline of the wide band cutting across his back.

Harry groaned as his hand found its way to a tiny strap. “Fuck.” He did this for me.

Harry fell to his knees. “I think you should be rewarded for your impressive display of devotion.”

Harry trailed his hands from those strappy silver heels all the way up a smooth leg. “You shaved.” Harry’s voice rumbled over the words.

“The girls cast a Dipilio before I made it out of the common room.” Scorpius muttered, completely distracted as Harry kissed, licked and bit the same path his hands followed.

As Harry reached the hem of the grey flannel skirt, Scorpius bunched it in his hands.

Hiding beneath the skirt, Scorpius’s hard cock was trapped in a tiny pair of silver lace knickers. It had caught on the waistband and was awkwardly pointing towards his hip bone rather than his navel, ready to burst through its prison any moment. His left bullock hung on the outside of the knickers, slightly pinched as the lace separated the two bollocks uncomfortably.

Harry memorized every minute detail of the gorgeous sight. It was nothing he had ever seen, nothing he had ever dreamt he’d want to see. But Scorpius standing there showing himself off, dressed like a trollop, was delicious.

“Unbutton your shirt,” he commanded.

Scorpius chuckled and reached for his tie. “Yes, sir.”

Harry smirked, “leave the tie on.”

Scorpius quickly loosened his tie and pulled it from his collar, then worked through the buttons of his blouse while Harry watched, riveted.

Scorpius pulled the blouse free from the skirt and opened it wide. The sight was stunning, a matching lace bra – clearly too small for Scorpius’s frame – cut tightly across his chest, pressing red grooves into the pale skin. The scorpion tattoo skittered back and forth excitedly. The sight of it was comforting, a reminder of each time Harry had seen it both innocently and not so innocently.

“Beautiful,” Harry whispered, his voice rasping and eyes hooded. “You are fucking beautiful, you know that?” Scorpius’s face flamed red, perfecting the image. Scorpius did this all for him, allowed himself to be dressed like this to protect Harry even after Harry had treated him shoddily.

Harry was disgusted with himself.

“What would you like, Scorpius?” Harry offered, still on his knees. “I’m yours. Anything you want.” At the moment he would deny Scorpius nothing.

Harry watched the surprise play across Scorpius’s features. When Scorpius spoke, it was once again full of the bravado he showed the rest of the world. “Go sit on the professor’s chair, sir. And open your robe.”

Harry complied without a word. He sat in the chair and waited, his cock jutting nicely beneath his exposed pants.

Scorpius stood over him and thought for a minute. “Pants off, if you please.”

Harry snorted and stripped out of his pants.

Scorpius gave a coy, perfectly wicked smile. “Good of you to stop by this morning, Harry.” Scorpius hopped onto Harry’s lap, his knees straddling Harry’s hips.

Harry chuckled. “Comfortable?”

“Very, sir.” Scorpius stuck a finger into his mouth and obscenely covered it with saliva. Harry’s cock jumped.

“You are incredible. I haven’t been able to stop thinking about you, Scorpius,” Harry admitted as he watched Scorpius reach behind himself, pushing his knickers to the side just enough to press his finger into his hole.

“I’ve missed you, too.” Scorpius’s voice was getting breathless. “Just one night. I thought it would be enough.” Ugh “Just a tease.” Harry sat motionless, unable to take his eyes off the hypnotic sight of Scorpius fingering himself. With each push, Scorpius pressed himself against Harry’s trapped cock.

Unable to stand it any longer, Harry reached into his robe pocket and found a tiny bottle of oil that he’d hidden there this morning. He coated his fingers with it and held them up to Scorpius for approval.

Receiving a nod, he slapped Scorpius’s hand away and pressed in two fingers. Nngghh Scorpius cried out in pleasure. It was the most glorious sound in the world.

With both hands free Scorpius flipped up his skirt, tucking the hem into the waist band. His cock was still trapped and awkward, the silver lace pulled tight to the side, to allow for Harry’s fingers. With his left hand, Harry pulled a bit at the stretched knickers and Scorpius’s cock sprang free.

“Scorpius Malfoy, there are rules of proper attire. What were you thinking, appearing in public like this?” Harry teased and curled his fingers to stroke the right spot.

Nnnnngh “Please,” Scorpius squirmed above him, eyes wide, begging for more.

Harry added a third finger, stroking until Scorpius whimpered.

“Every man in this school is going to be tossing off tonight to the thought of you.” Harry pulled out his fingers and slicked both his and Scorpius’s cock.

“What about you, Harry?” Scorpius hissed as Harry clutched his cock in a possessive grip. “Are you going to wank off to me tonight?” He writhed impatiently, urging Harry forward.

“Every night.” Harry lined up and felt the tight ring start to yield. “Oh God. Every fucking night.”

Scorpius impaled himself in one swift movement.

Ugh “Fuuuuuck.” Scorpius cried out.

The delicate lace of the knickers scratched lightly against Harry’s cock as Scorpius lifted his arse; it was just barely a tickle but it was constant reminder of the sinful garment.

Scorpius was lost for a minute, whispering jumbles of words, Fuck. So good. He rested his head on Harry’s shoulder, soaking it in sweat and Harry hoped not tears. But Scorpius found his voice again, “me, too. I thought I’d never…” He cleared his throat and wiggled his hips.

Harry groaned and tried to thrust. It was enough to snap Scorpius into action and he began rocking gently, painfully slowly, until it was Harry’s turn to whimper.

Harry moved Scorpius’s legs – god, so silky smooth – further apart to allow him more room to move. He thrust up and Scorpius keened and tilted his hips to meet him. Scorpius’s tattoo circled his navel at a frantic pace.

“How could I ever,”– thrust –”think to give you up,”– thrust –“your arse is the sweetest”– thrust –“in England.”

“Ugh, fuck. Only you will ever know.”

“So damn hot, Scorpius. You are – Merlin – so tight.” Harry leaned in and pressed a sloppy kiss onto lipstick-stained lips.

The chair squeaked in protest as the rhythm picked up, Scorpius furiously pounding himself onto Harry’s cock.

Harry slipped his hand between them and fisted Scorpius’s aching cock. He pumped with each thrust, feeling the coarse lace with each downstroke of his hand, matching the delicate scratching by his cock.

“Only me, Scorpius.”

Scorpius gave a loud grunt and his come splattered his tattoo, immediately reflecting the flashes of colour.

“Only you.” Scorpius whispered.

A dozen more thrusts and Harry came, too. He couldn’t give this up. Never. And he certainly wouldn’t share. “Only me.”

He rested for a moment then, leaning Scorpius back, he licked the come off Scorpius’s chest, nuzzling the scorpion, sucking the flimsy material of the bra clean. He nipped Scorpius’s lace-covered nipple and whispered, “only me.”

Harry pressed a chaste kiss on Scorpius’s nose, trying to ignore the redness of his eyes. “Next time we need to find something other than a chair.”

“Next time?” Scorpius regarded him carefully, afraid to hope.

Harry cursed himself again. “Yes, next time. Why do you think I’m here?”

Scorpius smirked and looked down at his rather unusual outfit.

Harry laughed and shook his head. “No, I mean why I came to Hogwarts in the first place. I can’t stay away from you. I don’t even know why I tried, whether I thought it was for your good or mine, whatever. It was stupid.”

“Yes, it was.” Scorpius pecked his chin, his jaw– “Very stupid.” –his cheeks, his nose– “incredibly stupid–”

Harry fought to capture Scorpius’s lips and kissed him, long and hard, his hand winding tightly into fine, blond hair, every second of it thinking ‘I’m so sorry.’

Scorpius finally broke free and whispered, “It’s ok, you can make it up to me.” He wiggled in Harry’s lap, showing off his renewing erection.

~o~

“Harry, are you alright? You look a little flushed.”

“I’m sorry, what were you saying?”

“I was asking if you’d be willing to take on a few History of Magic lessons in the week before the ceremony. I think the students would find your point of view on those events enlightening,” explained Headmaster McMurrough.

Harry sipped his tea and observed the Headmaster, thankful that he was not a Legilimens. Listening to the man drone on about the details of a celebration weeks from now, his mind had drifted back to a few hours before: to enthusiastic fingers and tongues and arse, to pretty little knickers soaked with his come.

Staying at Hogwarts for a week would certainly have its benefits.
