Work Text:

 The last few days—no, the last few years—of Hermione Granger’s life had been something she never could have imagined back in her fourth year at Hogwarts. Back then, her greatest worry had been keeping her best friend alive through the Triwizard Tournament. Compared to now, that had felt almost… simple.

 

Harry's survival of the reincarnation of Tom Slytherin—as he was now known—had already turned her world upside down. But nothing, absolutely nothing, could have prepared her for her fifth year.

 

Not even Umbridge. Not even the woman’s sadistic treatment of Muggle-borns.

The true breaking point had come during lunch one ordinary afternoon, when shimmering letters appeared in front of many students and staff members in the Great Hall. Floating. Glowing. Waiting to be read.

 

Hermione remembered the moment hers appeared.

 

Dear Hermione Granger,

Fifth Year Prefect – Hogwarts School of Witchcraft and Wizardry

We hope this letter finds you whole and well.

This correspondence is to inform you that your Muggle-born status has been rescinded and amended to Half-blood. See below.

Jean Granger (née Bailey) – Muggle

Daniel Granger – Squib, of the Dagwood–Granger Line

Hermione Jean Granger – Half-blood, last descendant of the Dagwood Granger line

You are hereby summoned to present yourself before the Wizengamot in ten days for a convocation of all Lines.

—Lady Magic

 

She remembered looking up in shock to see similar letters hovering before dozens of others—gasps, whispers, tears breaking out across the Great Hall.

She had looked to Harry, half-expecting him to have received one as well… and felt an irrational wave of relief when he hadn’t. For once, something didn’t involve him.

 

She would tell him later, in the common room.

 

She never got the chance.

 

Ten days later, everything burned.

 

Lady Magic herself appeared before the Wizengamot—alongside Lord Death, Lord Time, and Lady Fate. They declared that magic was dying, poisoned by generations of petty wars, inbreeding, and corruption. The revelation of Dumbledore actually Grindelwald’s manipulations—engineering conflicts to one day rule—shattered what little faith remained in the old order.

 

The world tilted on its axis.

 

Lord Voldemort—now Lord Slytherin—had his soul forcibly restored by decree of Lord Death. His punishment: sterility. The Gaunt line would end with him. Upon his natural death, the Line of Slytherin would return to Magic itself. His descent into madness, fostered and encouraged by Dumbledore aka Grindelwald, was acknowledged—but his choices were still his own, and justice was not denied.

 

All magically coerced marriages were immediately stripped and nullified. Witches stood before the Wizengamot and spoke of the horrors they had endured had their bonds shattered before the court. Tears fell freely that day.

 

Seats in the Wizengamot held by those long past their prime were stripped and returned to their rightful heirs. The age of hoarded power ended.

 

Sirius Orion Black was declared innocent of all charges. Peter Pettigrew was dragged before the court by Lord Slytherin himself. Sirius was named Harry’s legal protector, and Lady Magic commanded him to teach the boy everything that had been withheld from him under the false Light.

 

Azkaban was purged. Curses and compulsions were stripped away. Some prisoners were freed. Others—those beyond redemption—were taken by Lord Death himself. Entire dark lines ended that day.

 

And then came the truth that shattered Hermione completely.

 

Harry James Potter—Emrys' heir. Future ruler of the wizarding world upon his seventeenth birthday.

 

And she—alongside Daphne Greengrass—had been chosen by Magic herself to stand beside him as his wives.

 

She had fainted in the Wizengamot.

 

Harry, in typical fashion, had taken the revelation by disappearing into the Room of Requirement and hexing anything that moved until he calmed down. But once the storm passed, he accepted his duty. Sirius became the father he should have had all along. Harry trained. Studied. Took his seat in the Wizengamot as crown prince, exactly as Lady Magic intended.

 

Five years had passed since then.

 

The birth rate had risen. Fear had loosened its grip. War was a memory instead of a prophecy.

 

And now, a week before her wedding, Hermione stood in her sitting room, pacing as she waited for Daphne Greengrass to arrive. Harry had sent an official Emrys summons—his expectations for his future wives laid bare.

 

She didn’t know what to expect.

 

The Floo flared green.

Daphne stepped through.

***********

Hermione took in Daphne’s appearance with a measured, sceptical eye. Where Hermione was all curves and hard-earned strength, Daphne was slight and angular, built with a delicacy that spoke of careful breeding rather than survival. Everything about her seemed precise—controlled, intentional—where Hermione’s presence carried weight, heat, and endurance. They were opposites in nearly every sense, shaped by entirely different worlds.

And yet, soon they would be family.

They would share a life with Harry—share his bed, his legacy, his future. They would bear his children and rule beside him, not beneath him. For Harry’s role was not one of domination but of balance and oversight, and both she and Daphne would take their seats in the Wizengamot as equals, holding voting power among the Lords and Ladies of the realm.

But today was not about titles or futures yet to be claimed.

Today was about understanding.

They had never spoken of expectations before. It was tradition among the Emery line that wives submitted willingly—not through coercion, but through choice. Consent was law. Loyalty is a gift freely given. Hermione watched as Daphne lifted a hand and enlarged the letter they had received together. The parchment unfurled with a soft rustle, and from within it, two small boxes dropped onto the table, each marked with a different seal.

Whatever came next would define everything.

 

To my future Lady Potter and Lady Black,

 In a few days, we'll be married, and since I haven't spoken to you both about what it will look like, and based on my reading, it's customary to send a letter. 

 

By decree of Lord Harry James Potter-Black-Emrys, I invite you to our home in two days' time. It is the expectation that you bring nothing with you except your wand and any pet you choose to bring. All belongings are to be forfeited and/or stored in your vault at Gringotts.

(Hermione luv, your books have already been copied and await you in the library at Emrys castle.) 

In the period before our bonding, you will each be provided with new belongings and everything else you may need to make your lives comfortable. 

I want you both to know that our marriage will be one of equality and mutual understanding, I will ask nothing of you that you are not willing to give freely and of your own volition. The next few days, you will be pampered and prepared for our wedding night and the two-week honeymoon that will follow. 

My expectations for our home and bedroom.

  • No wife will be allowed any form of contraception ever. Should you currently be using it, it is expected to be purged from your system beforehand.
  • Any concubine that I take will have no bearing on the legality of our marriage, and any subsequent children, whether by marriage or not, will be treated the same. 
  • You both will wear the Emerys tattoo and ring on our wedding night. These are permanent. I ask that no glamours be placed on your body when we are together. I want to see both of you as naturally as possible. 
  • Body hair is to be removed permanently by spell before we meet again. 
  • Our sex lives will be one of submission. I will never go against anything that you deem as hard no’s but my hope is that you document what they are and trust me to never go past them
  • We will share one bed after we are married, as sister-wives it is the expectation that you will be comfortable sexually with one another. Our honeymoon will be tropical in nature, and I only ask that you do not hide yourself and your body away from me. I want both of you, freely, and I intend to take what I want often.

 

If this letter requires a response, please reply through official means. Otherwise, I will see you both at our wedding. 

 

All my love,

Harry.

 

Both women read the letter stunned, could they submit to Harry’s requests and live the life of his chosen wife. Both women had a lot to think about. As Hermione was lost on that train of thought, she heard the floo flare and Dafne was gone.

********

Dafne had expected her marriage to be one of submission, maybe even violence. She was born and bred to pureblood society; her expectations of the life she would one day lead were grim. Never would she have imagined that one day she would be Queen, or rather co-Queen with Hermione Granger, to marry Harry Potter of all people. But here she was at a salon, removing body hair and priming for her wedding night. She had read between the lines of the letter he had sent. He wanted her naked and often, free to fuck her when he wanted to, how he wanted to. She would submit, she would obey, she would wear his tattoo and ring, whatever that was, and she would give him children. She had no ideas for politics, but she would do her duty as told to do. Was she particularly into women, no - but she wasn't against it and both Hermione and Harry were fit. So it should be easy enough. 

 

There she sat with her feet in stirrups, her pussy and legs freshly shone waiting for the Emrys medi-witch to place the ring and tattoo somewhere on her body. As she sat there exposed in the chair, she had an idea of what came next. Dafne watched as the medi-witch bustled in and sat on a stool between her legs

She felt a small pinch when the ring was fitted to her clit and then a cooling sensation when the wound was magically healed and the ring firmly in place. Finally, she watched the medi-witch swish her wand, and the Emry's coat of arms was branded to her mons, a small tattoo for the eyes of her future husband. The witch conjured a mirror so she would see the platinum band with a purple diamond hanging from her clit. He had branded her in his own right, hopefully he was nothing like the dark lord.

 

When she took in her surroundings, she watched as Hermione let out a squeak of surprise when her own ring was fastened and now they both sported the Emrys tattoo.

 

The wedding had been beautiful, and everything she could possibly imagine a royal wedding would be. Hermione and her had been fitted with tiaras befitting their station and the event. Greeting international dignitaries and making polite conversation with the other wives there. They both had been sent off early to prepare, and Harry would join them soon enough to officially invite them to his bed as his wives.

The room they shared was massive, the outer section held their clothes and belongings, an armoire and a chaise to get ready, complete with a full-length mirror. The room also sported a small library and a lounge chair good for reading or other activities. Both women just looked at each other, as there was no coming back from what came next.

As each woman removed their wedding dress and other adornments from the day, removing any glamour and letting their hair down. They stood naked in front of each other for the first time. They both knelt down in a submission position, waiting anxiously for Harry to arrive. 

 

Harry entered the outer room from the bedroom they would soon call their own and stood in front of them, no shirt or shoes. Just his pants, with his belt buckle undone.

 

“Hermione Granger, now Hermione Potter-Emrys. I invite you to our bedroom. Please rise. Dafne Greengrass, now Dafne Black-Emrys. I invite you to our bedroom. Please rise.”

 

Both women rose off the floor, where they now could see the same tattoo that adorned them was etched over his heart and the other side of the ring pierced on their clit, was dangling from his nipples representing each of them.

 

He took both of their hands, softly yet assuredly and led them to their new room. Inside was a large bed, big enough for three of them to sleep comfortably and, of course, for other activities. He made them both sit on the edge of the bed, where he stared at them drinking in their bodies. 

 

‘Lie back, ' he asked softly. He murmured an incantation and both women glowed pink.

“You're both fertile,” he said and smiled at each of them. He murmured another incantation and two balls of light, one from each woman floated to a waiting pedestal. All three watched as the balls of light settled into their resting place.

“Tonight, I have a duty. To magic and to my crown and I am Lord Emrys. Tomorrow and for the rest of our lives together. I'm just Harry. Do you understand?”

They both nodded their consent. Harry smiled.

“Good, and since neither of you wrote back, we are agreed on the terms of the letter?

They both nodded again.

Harry tilted his head, taking in the curves of their tits on display for him, legs locked as if scared of what he might ask.

“Can you show me the rings?” He asked, and with that, both women's knees spread apart, and using a hand each spread apart their lips to show the ring hanging from their clits.

“Hermione, do you want to see what Dafne’s ring looks like? Come here, love, let me show you.”

Hermione moved from where she was and joined her husband, at the end of the bed. All the while Harry was caressing the inside of Dafne's thighs. 

“Do you see how beautiful the ring of Emrys is, Hermione? How it shines and takes in the firelight. Do you see how the more I rub on Dafne's thighs, her clit grows, and the ring is prominent on display? Can you taste your sister-wife Hermione? Can you show me if she tastes as good as she looks?”

 

Hermione bent down and caressed Dafne's already wet entrance with her tongue and then glided it up and put the ring in her mouth, sucking on it. The moan from Dafne was soft and lewd. Harry grabbed my hair and pulled me in for a kiss, tasting Dafne on my lips. Pulling away he kissed Dafne then whispered something in her ear.

 

Hermione was told to lie down next so Harry could see her ring. Again caressing the inside of her legs. Dafne was made to eat her cunt and share the taste of her with her husband. When Harry shared the taste with her. He also whispered in her ear, telling her that the Emrys magic meant he would take them often tonight, and he fully intended to fuck her into the mattress over and over again. 

 

That night he had fucked them both, boneless. He had them in a sixty-nine position, while he watched and stroked his cock watching as both his wives explored the other for his viewing pleasure. He had Hermione ride his face while Dafne rode his cock, then switched. He fucked Hermione with her feet planted on his chest with her legs spread wide. He had Dafne bend over in front of his face, while she played with her own clit. She came with a splash all over his face, while he continued to hold onto Hermione and fuck her to completion. 

He fucked Dafne from behind, with her face in Hermione's cunt. For every stroke of his cock, Dafne sucked and licked at Hermione. When she was ready to come, Harry asked her to swipe at her clit hard, spraying her juices all over Dafne’s face.

Both women were on their knees sucking on his cock, one at the base and the other at the tip. Swirling and sucking, till he came with a roar all over their pretty faces, painting them with his come. 

He stretched Dafne's other hole, listening to her moaning pleasure. When he entered her tight passage. He made sure to grope and suck on Hermione's tits, painting her chest with his come.

Each new position, each orgasm he dragged from them only stirred the magic in the room. Both women would be pregnant by the end of their honeymoon as the magic had deemed it so. 

When his balls were empty-ish. They fell asleep in a tangle of limbs and post coital bliss.

 

The next morning they portkeyed to their honeymoon destination. 

A yacht, comfortable enough for the three of them, captained only by house-elves

Harry appreciated that his wives wore clothes that revealed their bodies. Thong swimwear for ocean swimming and nothing unless they were eating meals.

He fucked them on every part of the boat. On the deck he lifted the small dress that Hermione was wearing, palming her ass, he slid into her wet heat and fucked her against the railing. He had Dafne in the same spot later on that same day, with the sun beating down on her skin. He watched as her perfect tits bounced as she rode his cock. He ate them both out while they lay on top of each other, legs spread wide. Dafne rubbed her clit against Hermione. While Harry licked from one hole to the next. He bit love bites into every inch of skin he could find and made them both suck his cock while the sun set, so he could watch both beautiful views. Day after day, he fucked his wives, whenever and however he wanted. They were his and he could do with them as he pleased. He would never hurt them, but they would submit, they would obey and he would get what he wanted from both of them.

 

Six days into their honeymoon, the boat docked. They were staying at an Emrys property. That morning, when they awoke. Harry was not on the boat. Both women made their way to the house, taking in the property and where they would be staying for a few days.

Following the obvious layout of the home both Hermione and Dafne made their way to the dining room where both of the women froze in shock. There seated at the head of the table was Harry, head back, eyes blown wide in pleasure. Someone, they couldn't see who, was sucking his cock under the table. His moans of pleasure reverberated the room. Dafne recovered first, taking in the scene and moved. She walked to his seat and kissed him softly, wishing him a good morning. Then she sat as if nothing was the matter and proceeded to eat her meal. Nothing changed, the slurping sound was lewd and Harry was directing the woman's head, deep throating his cock. Hermione, however, did not recover as easily. She turned around and walked swiftly from the room. Seeing this, Harry didn't move to change what was happening. He glanced over at Dafne, eyes still hooded, nodded once in thought then continued to let the woman on the floor suck his cock, like nothing was the matter. When Harry came, and the woman rose off the floor, Dafne gasped. It was the former Lady Malfoy, now known as Narcissa Black.

 

That same night, after Harry had fucked his wife to sleep, and he could hear the soft breaths of Dafne, deep in sleep. He called a house elf, quietly asking where his wife was.  Displeased to hear that she had chosen to sleep in a guest bedroom, but left her alone for now. His earlier conversation with Dafne about her feelings of discomfort about sitting a Wizengamot seat, was listened to with quiet ease. They would make a plan together for her to pursue other goals. She had time before she would need to take the Black seat, Sirius would sit in her stead. In the morning he would deal with Hermione.

*******

The following afternoon, he found his wife in the library, deeply engrossed in a book. She was wearing clothes not befitting his request, her hair was up and he could see tears streaming down her face. He sighed.

 

“Hermione," he asked softly, “what have I done that you found the need to not sleep in our bed.”

Hermione's eyes flashed angrily and huffed in annoyance.  “There was a woman sucking your cock in the dining room, Harry.” She spat his name like a curse word.

Harry’s eyes narrowed, he pried the book from her hands and proceeded to pick up his wife and throw her over his shoulder. She spluttered, not expecting his reaction. Then winced when she felt the hard slap on her ass and the stern voice of “behave” left Harry’s mouth. He walked her up the stairs and down hallways to a room that he unlocked with his Lordship ring. When the lights came on, Hermione took in the room with a gasp. There were butt plugs, a table with clasps where the feet and hands went, a vaulted table, many whips and dildos of various sizes surrounding the room. But what was most prominent was the throne-like chair that sat regally in the center of the room. Harry dropped Hermione unceremoniously on the floor, then sealed and silenced the room.

 

“Hermione,” he said, voice seeming tired and exasperated “when I sent you the letter before we were married. It did mention concubines, did it not?”

She shook her head yes but didn't say anything. 

“Is the issue that you saw me with another woman or is the issue that it's our honeymoon and you weren't expecting any other woman. Or is this issue that you have to share me?”

Hermione sighed and said in a quiet voice that she was still coming to terms with sharing him with other women. Harry sighed and with a flick of his wand, she was naked and his favorite curls flowed down her back just the way he liked.

“Stand up Hermione. I'll only say this once then we will never have this conversation again.” He watched as she stood and squared her shoulders waiting.

“I am Lord Emrys, I am not the same boy you knew in school. I've seen magic you would never believe and I have a duty to crown and country to rule. It is my right as ruler to have a home and family as I see fit. That includes my wives and any concubines I choose. Narcissa is one of them. We have a mutually beneficial agreement whose details you do not need to know. As my wife, you have been afforded a Wizengamot seat and the privilege of being in my inner circle of advisors for my reign. However, with those privileges comes the knowledge that there will be things you see and don't like and I will do things you don't approve of.  As my wife you can and should come to me and speak about your concerns. I will listen and take anything you say to me under advisement. What I will not tolerate is bratty behaviour and not speaking to me when you are upset and I especially will not tolerate you sleeping somewhere other than our bed. You read the contract Hermione, I laid out how our marriage would look like. You and Dafne wear my ring and I don't mean that trinket on your hand. Since you agreed and find problems with your agreement it is my right as your Lord husband to punish you.”

 Harry’s hand shot out so fast, she was shocked when she found herself bent over Harry's lap with her ass up in the air. He spread her legs wide over his knee exposing the real bonding ring attached to her clit. He pulled at it, pulling a hiss of pain from his wife. 

“Apologize Hermione”, a hard slap over her ass and cunt. The sound loud and crass

“You are my wife and I love you,” another slap

“You will act as is your station, and use your words” another slap

“You will sleep in our bed, as befits your position as my wife” another slap, this one intently hitting her ring

And  on he went, with words of endearment advising her of her place at his side and in his heart. That she needed to separate the two, it would be easier on her that way,

At the tenth slap, she thought she would come and by the fifteenth she did. All over his hand and down her legs. She fell from his lap boneless. He said nothing, just unsilenced the room and walked out. Leaving her there to consider her life choices.

 

Harry made his way to Narcissa’s suite, he was frustrated. He remembered gifting her this home as a safe haven when she left Lucius some years ago. She was there throughout his training and development, first as an authority figure, but now she had her other uses. Her mouth and ass, being  two of them. He found her in her room, bent over her desk with her ass cheeks open on display. There the Emrys emblem shone brightly on a butt plug he had gifted her last year.

 

He smiled at the display of submission. He had total control of her body, he could edge her to his heart's content or fuck her boneless. Now though he needed to relieve some stress and knew just what he wanted. Later he would take his wives for a walk around the property and introduce them to the surrounding areas. Now though, he opened a drawer and removed a dual tailed whip. He watched as Narcissa smiled brightly at his choice. He would work her over then fuck her plugged hole.

******

Later that night, Hermione walked sheepishly back into their room. She regarded Dafne who smiled at her but said nothing, she entered the room and assumed the same position she met him in the first night of their honeymoon.

“I am sorry My Lord husband Emrys and Lady wife Black-Emrys. My outburst was uncalled for and it won't happen again.”

Dafne had just looked down at her and smiled. Hermione had come back to their marital room, she had come naked, hair out as was her Lords’ wish and she had apologized. Dafne knew what she had signed up for being Harry’s wife, but could understand Hermione's emotional outburst.

Harry sighed. “Rise, my Lady wife Potter. I only like seeing you on your knees when my cock is in your mouth. Now come here, my right side is empty and your place is by my side. Hermione made her way to Harry’s right and crawled into his waiting arms. He kissed the crown of her hair and went back to the book he was reading.

 

“In two days we will be leaving here. I want to be young and carefree for one day. So I got us tickets to a theme park in Florida. We’ll do all the fun stuff before we come back to Britain and ruling.” Hermione and Dafne both smiled and jumped on him. Their playfulness led to heated touches and the next was Hermione deep throating his cock and Dafne riding his face. He gripped Dafne's legs tight, urging her back and forth along his tongue, pulling and tugging at her bonding ring until she came with his name on her lips. He pulled Hermione off his cock and flipped her over on the bed. With a muttered spell, her puckered hole was lubed and stretched. She hissed when he pushed in then moaned deeply when the feeling became pleasurable. He grabbed her hips tightly while he slammed into her ass over and over, then flipped her over again and pushed into her wet heat. Hands above her head, tits bouncing with each push of his cock. He asked Dafne to play with Hermione's clit. He spread Hermione's leg wide so Daphne's face could reach down and watched mesmerized as his cock pushed in and out. It was an exhausting night of different positions and words of love and affirmation to both his wives. He ensured to paint their walls with his come, after all he had a duty to perform. 

 

It was three days later when they returned home. The theme park had been fun and relaxing. But it was now time to get back to work. Each wife had something to do and he had ordered the elves to unpack. Harry made his way back to his room to check on the glowing fertility balls he had left there. The colour had changed to a dark blue and green. He smiled and wondered which wife carried twin boys and which one carried a boy and a girl. He smiled nonetheless. He would show them later. He had matters to attend to and a life to continue to build.
