A/N: This is a shameless bit of fluffy smut. This is the first lemon I have ever written so be kind, please. I don't really love the Percy from the movies so insert any handsome ginger man you want here.
"What do you know about Family Magic Rites?" Harriet asked from her position in an over-sized leather armchair.
Percy stiffened for a mere second before he took a sip of his firewhiskey, observing her shrewdly over the top of the crystal tumbler.
"A great deal, as I'm sure you do Lady Slytherin." Percy responded evenly, putting emphasis on her title.
Lord Percival Prewett was the only member of his family sorted into Slytherin, and was a prefect when Harriet had been sorted into Slytherin herself.
He was forever trying to get her to take her newfound title more seriously, and behave as she ought.
For her part, Harriet attempted to get him to have a bit of fun, giving him the nickname "Percy" that he only endured from her.
He was Lord Prewett to all others.
The title had skipped over his other brothers to land on his capable shoulders, and he wore it very well.
Harriett fought the urge to sass him, she needed his help.
There were whispers of Lord Voldemort trying to return, and the once great Lord Tom Marvolo Slytherin could not be allowed to return to his corporeal form.
He had delved deep into magic so Dark it should never have existed. It had torn his soul and sanity to pieces, and all that remained was a murderous raving lunatic.
"Did you know there is a way to strip one of their family magic?" Harriet asked.
Percy set down his glass.
He leaned forward, rested his forearms on his legs and gestured for her to continue.
"I read about it in the restricted section just before I came here for Yule. It often kills the person who's magic it strips, especially if they are in poor health. Their souls and bodies are too weak to go on without it. Isn't that interesting?"
Percy sat back in his chair, looking at her calculatingly.
"Very interesting." He said simply as he quirked one auburn eyebrow at her. He picked up his glass and took another long sip, returning his gaze to the fireplace.
This was why Harriet loved talking to Percy so much. There was so much said with so few words.
A single rise of an eyebrow or a quirk of his lips could tell her more than most people's mindless ramblings.
Percy was extremely intelligent. They were on an even playing field when they spoke, though he did have the advantage of several years on her.
Harriet had inherited the title of Lady Potter upon her parents death, but she had not gained the title of Lady Slytherin until her second year of Hogwarts. It was her third time defeating Voldemort, this time in the form of Tom Riddle.
Due to her distant relation to Salazar Slytherin, and through "right of conquest"-when you defeat a witch or wizard three times in a row- she had inherited the title, magic, and vaults that came along with it.
The scrolls from Gringotts explaining it all had been waiting at her bedside along with Percy when she awoke in the hospital wing.
Harriet rose to her feet, plucked the glass out of Percy's hand and vanished it with a quick bit of wandless magic.
With it gone she took a seat on Percy's lap and snuggled into his side.
"What are you doing Harriet?" He asked softly, dropping her title, though he had already begun to loop an arm around her back protectively.
This was their way. He had always allowed her to cuddle up to him for comfort, though he always had something to say about the impropriety of it.
Harriet just hummed her usual acknowledgement and tucked her face into his chest, breathing in his familiar scent of ink and parchment.
He wasn't as tall as his other brothers, but he was still much bigger than her, and his magic made him an impressive sight.
It fairly radiated off of him. The Prewett Magic was old Dark Magic that had a fierce protective streak running through its core. It spoke to her Slytherin Magic in a way that most others didn't.
"What's the problem Harriet? This should be a good thing." Percy asked, running his hand up
and down her back soothingly.
Harriet mumbled into his chest incoherently, and Percy pushed her back gently so he could look down at her face.
Harriet tried to avoid looking in his eyes, afraid what hers would give away, but Percy was having none of it.
He put one hand on her jaw, holding her face in place.
"Now what was that?" He asked again slowly, as if afraid she would flee.
"My magic isn't stable enough for me to perform the ritual, since Sirius passed. I would have to bond with a powerful Dark wizard to be able to use it."
Percy released her now that she had spoken, and allowed her to snuggle into his chest once again.
So that was why she was so upset. She would have to bond, and soon.
Familial bonds stabilized a witch or wizard's magic, allowing them to perform more complex rituals.
With a massive amount of Dark Magic, like in the case of the Slytherin Family Magic, it could be an enormous burden to bear alone.
Percy continued to run one hand over Harriet's back soothingly as he thought.
Harriet was seventeen now, of legal age in the wizarding world. She would graduate in just a few months. Many of their housemates would go through binding ceremonies as soon as they graduated.
Most of Harriet's Slytherin year mates had begun courting in the year prior, but Harriet had steadfastly turned down every offer she received.
She had no desire to paint a target on someone's back and admittedly, no one in her year appealed to her.
She had long ago fallen for Percy, though she had little confidence that he would ever return her feelings.
He had seen her at what she considered her worst- an awkward eleven year old.
All malnourished from mistreatment by her muggle relatives and ignorant of the new world she found herself thrust into.
It was Percy that realized she was sickly, and not just naturally small. He had gone to Madame Pomphrey and they started her on a potion regimen to correct some of the damage that had been done.
Percy was the one who educated her about her magical heritage, and taught her to navigate Slytherin and all of it's endless politics.
He had also taught her a few nasty hexes to use on anyone who dared to talk about her mother's heritage.
If he just so happened to be looking the other way every time it happened...well he couldn't control that, could he?!
Percy fought the urge to smirk at the memory. She had always been a little spit-fire.
He had planned to send Harriet a courtship offer after her graduation. She had been adamant that she would not entertain any offers over the last year, but clearly things had changed.
He had grown to love her and her mischievous ways.
No one else could draw his attention away from his duties as Lord Prewett, or drive him crazy more effectively than Harriet.
Somewhere along the way her sharp angles had filled out into supple curves. Her once short black hair now hung elegantly to her hips, sparking with her Magick when she was particularly angry.
He would be lying if he said he was immune to her charms, and Lord Prewett was no liar.
Now here she was, sitting in his lap and telling him she needed to bond to a Dark wizard to be able to perform the one ritual that had a chance of ridding the wizarding world of it's greatest danger.
Prewett Magic was Dark, more than most knew, but he knew Harriet could sense it. She had a gift for magic sensing.
He had always thought that was why she gravitated towards him. They had sympathetic magic.
Her magic sought his out, and his longed to pour into hers through a soul bond. He had held it on a tight leash for years, especially since Harriet had come of age.
Percy stilled his hand from it's soothing pattern and Harriet immediately popped up to look at his face.
Was everything okay?
Percy's eyes flicked over her face, examining it closely. He raised a hand to cup her face reverently.
Harriet felt her stomach swoop at the look in his eyes, their faces were only inches apart.
Harriet leaned forward slowly, giving him time to pull away if he wanted to. Once she kissed him, they would be betrothed.
She doubted she would be able to keep her magic from flooding over him and beginning the bonding once their lips touched, she had loved him for far too long.
Percy stared back at her and closed the last hairsbreadth of space that Harriet had left between their lips, taking her first kiss.
At the contact, Percy could not help but hold her tighter, causing Harriet to shift so she was straddling him.
The Slytherin Magic was flooding through Percy, beginning to bond their souls as they kissed each other fervently.
The Slytherin Magic was deep, and Dark, and seductive, just like Harriet.
Percy briefly wondered how she had borne this much magic by herself before his mind was much more pleasantly occupied.
Harriet was lacing her hands through Percys' auburn hair and pressing herself ever closer to him.
Her heart was pounding in her chest. She hadn't dared to hope that Percy would bond with her, that he would find her desirable.
She felt the bonding magic encouraging her to seal the bond, taking away any shyness she may have felt.
Harriet began to feel the bond with Percy forming in her magical core, and she moaned out loud at the feelings that were surging through her.
The sound seemed to spurn Percy on, because he stood, grabbed her by the back of her thighs, and carried her through Prewett Manor as she littered his neck with kisses.
Harriet was so preoccupied that she didn't even register that they had entered his private chambers until he was setting her carefully on his sprawling bed.
Harriet tried to catch her breath as Percy reached to undo the buttons on her blouse.
"If we do this, if we seal the bond, you can't go back to Hogwarts. They don't allow bonded students. I won't let you out of my sight for months, Harriet."
His voice was low and husky and it sent a thrill through Harriet to know she had affected him in such a way.
She nodded her agreement jerkily, and reached for his shirt, pulling the hem out of his pants and stripping it off his body as quickly as she could.
Right now, Hogwarts could burn for all she cared.
She needed Percy in a way she had never needed anyone else, and she would have him.
Percy climbed onto the bed with Harriet and finally let go of the tight rein that he held on his magic.
It washed over Harriet as she rose onto her knees to meet Percy in another furious kiss. It was so much more than she had ever suspected.
It was nearly as old as the Slytherin magic, and just as Dark.
She felt it tingle along Percy's skin as she touched him, and tasted it as she licked and bit along his neck. It left a trail of fire down her body as Percy's hands roamed.
Harriet felt as if she might actually catch fire as Percy's hand dipped between her legs, preparing her to seal the bond. Her legs shook and her insides clenched at the things Percy's hands and lips were doing to her body.
Harriet reached a tentative hand down to stroke Percy, wanting to bring him as much pleasure as he was bringing her.
Percy shuddered against her and whispered her name hoarsely against her throat, as if trying to restrain himself.
"Percy, please. Don't hold back. Not now." She whispered back, and suddenly she was underneath Percy as he braced himself over her.
He stroked her face tenderly, looking into her eyes by the moonlight that was coming in the large windows.
"You're sure?" he asked, and Harriett had barely gotten out her exclamation of "Merlin, yes!" when she felt Percy thrust into her.
Her magic soared once again as Percy began to thrust slowly, carefully, as if afraid she might break.
She felt her magic and his tingle along her skin. The soul bond was solidifying in her magical core, and as it became more solid she felt her climax approach.
The feeling of completion as Percy began to thrust harder and faster was overwhelming.
The physical sensations mixed with the ones of the binding magic mixed until she couldn't tell which was which.
Percy tried to pace himself, enjoying the bonding night with his precious Harriett, while simultaneously being overwhelmed at every turn.
He had no idea when she came to Prewett Manor what was on her mind, let alone that she would be his soul-bonded wife by the end of the night.
His magic crowed at finally being allowed to soul-bond with Harriet. He drowned in her heady magic and let her bathe in his own in return.
To have her in his bed, moaning his name as she began to clench around him was absolutely transcendent.
The bond solidified in their magical cores as they came undone, and Percy knew he meant what he said when he warned her he wouldn't be letting ehr out of his sight anytime soon.
He kissed her head as he drew her to snuggle into his side, both exhausted from their exertions, still basking in the bonding magic.
"We'll do the ritual tomorrow love, don't worry. His reign of terror is as good as over." Percy told her reassuringly.
And it was.
Fin.
