Crazy? I Was Crazy Once
-
“I just don’t understand why your sister would want a visit from me?” Harry exclaimed. From beside him on the couch Narcissa rolled her eyes.
“As I said yesterday my lord I do not either. I have not dared to assume what goes on inside Bella’s head for quite some time.”
Harry ran a hand through Pansy’s hair. The brunette girl was currently lying across the couch with her mouth wrapped around his cock. The girl hadn’t even been asked to blow him, instead choosing to do so randomly of her own volition. Either she was starting to enjoy performing such acts or she wanted a bigger allowance.
He hummed in both pleasure and acknowledgment at her words. “Still, I can’t imagine any scenario ending well.”
“Then why are you even considering on going?” Narcissa huffed. The older woman had a fashion catalog in her left hand as she perused the expensive garments within. Her right hand was softly caressing the younger girl’s supple bum as she swallowed their lord’s cock.
Harry simply shrugged, his hips twitching slightly as Pansy switched from his cock to his balls. “Curiosity I guess? Hermione always said it would get me killed.”
“I hate to say it my lord, but in this situation I believe your mud- muggleborn friend to be right.” 
Harry gave a warning look at her almost slip up. He had made it clear that the word mudblood or any variation of it would not be tolerated, especially in his home. It was one of the more difficult personality aspects of the women to deal with, but one that was getting better. Narcissa and Pansy had almost completely forgone the use of such slurs, with only a few hiccups here and there. Astoria however was the worst by far, even after the numerous spankings.
At this point he was starting to assume she liked them. He wondered if there was another word for a brat in the wizarding world?
With a sigh he turned away, much too content with Pansy’s wet tongue lathering his shaft to care about punishing the blonde. “Still, aren’t you the least bit curious as to why?”
“I suppose I am, though I’m hesitant to actually see her. I gave up on Bellatrix a long time ago, the woman she is now is no longer my sister.” Narcissa said forlornly, fashion magazine thrown to the side forgotten.
Harry reached over and took her hand within his. “I know. Whatever you decide is what we’ll do. Just know that I’ll be by your side the entire time.”
Narcissa smiled back at him before leaning forward with her eyes closed. Harry met her halfway, his lips capturing her own in a tender embrace. Their mouths danced together for quite a while, neither pressing deeper, just content to share the loving moment.
Unfortunately said moment was broken with a grunt from Harry. His hands flew down to press Pansy’s mouth further onto his cock as he came. The brunette took it all in stride, allowing the hot sticky liquid to shoot down her throat. Narcissa merely giggled at him before her eyes softened and she placed one last quick kiss on his lips.
She stood with a sigh. “Well I suppose if we’re to see my sister I’ll need to look my best. Pansy dear would you like to go dress shopping with me?”
The girl pulled off his cock with a wet slurp. Placing one last lick upon the tip she jumped up in excitement. 
“I would love to!”
“Excellent, finish up here and we’ll leave. In the meantime I’ll just run up and have a quick shower!” Narcissa said with a smile. The woman hummed as she left, most likely excited at the chance to spend another fortune on dresses.
Pansy wasted no time in straddling him. Her bare mound trapped his cock between her wet folds. While she wasn’t nude, she was damn close to it. A tight button up shirt trapped her round breasts, the material tied off around her tits and stretched almost to its limit. Her toned stomach was exposed and a very short plaid skirt concealed her shapely bum, but only barely. Harry had never understood the whole school girl kink thing… until now.
“You know when Narcissa said you could start wearing what you wished, she meant panties too.” He said with a laugh.
The brunette merely smiled back with a demure grin. Her hips began to move, grinding her slick cunt against the underside of his length.
“I know, but then I wouldn’t be able to do this now would I?” She responded innocently.
Harry growled back, reaching down to lift her plush bottom and spear her with his thick cock. Pansy howled in ecstasy at the sudden intrusion, pussy walls clamping down intensely around his cock. 
“I suppose that’s true. I do so love ruining this tight pussy.” He whispered into her ear. The girl shivered at his words, her hips moving of their own volition as she started to bounce upon his thick shaft.
Lewd sounds filled the room as her pussy gushed around his cock. Cut grunts flew from the girl’s mouth as she bounced herself on his lap. Her velvety walls massaged his meaty pole with every deep stroke. Already she had came once as she milked him, pussy juices leaking out to stain the expensive upholstery under them.
She stared deeply into his eyes as she worked. The green jewels within blazing with lust fueled fire. A shiver ran up her spine at that look, her pussy gushing just a little at the sheer intensity of want in his eyes. It was moments like these that reminded the girl exactly who owned her. She was his to dominate, to fuck, to use, and she would gladly let him with a smile on her face. After all, being a magic bound concubine wasn’t so bad when you had a massive cock to fuck you stupid.
Her pussy tightened without warning, pleasure attacking her nerves like a bludger causing her back to arch and a scream to leave her lips in response. Her climax was met with a warm sensation flooding her womb as her lord grasped her hips tightly and filled her with his seed. Spurt after spurt of the creamy liquid coated her walls and only after he was finally finished releasing his sticky cum inside her did she collapse forward bonelessly, her pussy still twitching from her own orgasm.
It was that moment that Narcissa descended down the stairs dressed in a new set of expensive robes.
“Are you ready dear?” She asked, fiddling with a large diamond earring.
The previously comatose girl jumped up like a flash, cum leaking down her thigh as she stood.
“Yep!”
“Wonderful! We’ll be back later this evening love. Astoria will be here in an hour if you’re still horny by then. Ta!” With that the two women whisked down the hall and out the door before Harry could say a word. He took one look down at his still hard cock before grumbling in irritation.
“Astoria better hurry up.” He said with a scowl.
-
In the end Astoria had shown up earlier than expected and promptly enjoyed a very vigorous fuck session atop the kitchen counter. 
Narcissa had chastised him for that later on, arguing that it was extremely unsanitary. Though considering   later that night she ate his cum out of Pansy’s pussy as he plowed into her ass from behind, he would say she was being very hypocritical.
It was a week later that they were finally able to see Bellatrix. Apparently it wasn’t as simple as just popping on by and asking to see the notorious mass murderer. Harry had to contact Kingsley to even get anywhere and even then it took some time to get the proper approvals and set everything up.
The day finally dawned though, and hand in hand Harry and Narcissa walked through the ministry. As outsiders weren’t technically allowed on the island, most visitations happened through floo calls or, in special cases, ministry holding cells. 
The latter was usually only reserved for special situations such as family matters, lawyer visits, or the occasional bribe. Thankfully the ministry had seen virtually none of the last option since Voldemort fell. Their own in person visit was primarily due to Harry’s standing in society and the fact that no one in their right mind would let Bellatrix Lestrange near a working floo. Not that Harry thought it would be an issue.
According to the reports Kingsley received from the prison, ever since the trial Bellatrix had hardly ate or spoke. Many of the guards said that the witch spent much of her time in bouts of either melancholy or quiet contemplation. With the dementors no longer used for guarding Azkaban, there was little explanation for the former and even less for the latter.
Everyone, including Harry, fully expected the witch to act quite similar to her last stint in jail. Angry and unpredictable with an added bonus of crazed ramblings. They couldn’t have been more wrong.
As he and Narcissa walked into the appointed meeting room, Harry was met with the sight of a very different Bellatrix. She was still just as pale and gaunt as he remembered, but her hair was much more tamed. While it still fell down in river of dark curls, it wasn’t the frazzled and unkept mess he was used to. She held herself differently too. Where before she was like a caged animal, hackles raised and ready to kill at a moments notice, now she sat calm and collected with her chin up high and back straight. She looked…regal. She looked like Narcissa.
The ex-Death Eater was sat in a cage similar to the one at her trial clad in a dirty set of prison rags. Her arms were spread wide, each hand chained to opposite sides of the metal cell. The bulky iron collar around her neck glowed blue with a myriad of runes, not a single one he could identify. Even with all the security precautions and the unwashed Azkaban grime, she still held herself as if she were just another pureblood princess.
It made him more uneasy than crazy Bellatrix ever did.
Her lilac eyes followed them until they sat in the chairs provided. They stared at one another for a few moments, Bellatrix’s eyes searching for…something. Finally, after a tense silence she spoke.
“My lord.” She intoned, her eyes casted low. “I would curtsy as custom but…” 
The chains binding her hands shook slightly as she gestured. A bemused expression on her face as if she was saying ‘What can ya do?’
Harry regarded her cooly, searching for anything that would give her game away. “I think we can forgo the formalities under the circumstances.” 
She simply nodded back, her eyes turning to meet her sister. “It’s good to see you Cissy.”
“Why did you ask us here Bellatrix?” Narcissa bit out, ignoring her sister’s greeting. The black haired woman sighed, her gaze becoming unfocused.
“I didn’t know.” She whispered.
The younger Black sister scoffed, “Don’t play games! You requested this visit!”
“Not about that!” Bellatrix bit back. Taking a breath the witch continued. “I meant I didn’t know what I was getting myself into when I pledged myself to him.” 
Harry didn’t need to guess on who ‘he’ was. “And? What are you trying to say, it was all a mistake? That you were brainwashed or some shit like that?”
“No my lord, I take full responsibility for my actions but you don’t know the full story. Neither does Cissy or…Andy.” With the last word Bellatrix’s eyes scrunched up in apparent anguish. “Look I knew what his cause meant. I was young and stupid. I thought myself better because I was a pureblood and that others were beneath me. I just didn’t understand the weight of my choice.”
Her voice gained a heated tinge as she spoke. “I wanted to bring glory to House Black. Prove that we and every other pureblood were superior. Thought we’d do a few raids, torture a few muggles, and the ministry would ‘bow before our might’ or whatever shite he was spouting back then. I never wanted it to go as far as it did.” She spat. “But then he saw my skill.”
She swallowed thickly, “When we swore fealty to him, we swore everything. Our bodies, minds, and…souls. It was small at first, a few rituals to ‘make me stronger’” She laughed. “They were really meant to bind me further to him. A body can heal, the mind can be soothed, but the soul? Once you damage that there is very little that can be done to help it. I believe you would know a thing or two about that my lord?”
Harry narrowed his eyes at her words. In truth few knew or his tenure as one of Voldemort’s horcruxes. It wasn’t something the general public would accept quietly after all. 
“I’m a smart witch, despite my mental… deficits. I can put two and two together. Regardless, the soul fragment in your head is gone now and it matters little. However, the damage to my soul remains.”
“And this is what caused your insanity?” Narcissa said with suspicious eyes.
Bellatrix shook her head. “Not cause it, but certainly increase the severity. We both heard the stories of the Black madness from grandfather. It seems I suffered from it, or could have later on in life if not for the rituals. They in a sense tied me to him even deeper than the dark mark did. As his soul fractured and mind frayed so too did mine. His wants became mine and my soul became his.”
Tears sprang up in the gaunt woman’s eyes. “I will not deny that I joined his cause for less than innocent reasons, but if I had known what it would cost me, what I would lose? Well, I would have killed the bastard myself.”
“What you would lose?” Harry snarled, “What of the people you murdered? Of the families you destroyed and lives torn apart? You say these things as if I should have pity for you! Even now the only thing you speak of is yourself and what you lost!”
The image of Sirius, blank faced and limp as he fell through the veil came to the forefront of his mind. This time it was his eyes that filled with tears as the long healed grief for the man came back with a vengeance. Narcissa’s hand came up to grasp his tightly, her eyes concerned as she rubbed small circles into his palm.
His rage cooled and he turned back to face the dark witch. “Even if this is true, it doesn’t just erase… everything you’ve done.”
“Nor would I want it to. My actions may have been clouded or not fully my own but you’re right that it does not make them right. I take full responsibility for my actions and I will surely suffer for them in the next life.”
“Then if you didn’t ask me here for leniency, what did you want?” Harry asked.
Bellatrix smiled for the first time since they entered the room. Not a cruel wicked smirk, but a small saddened   smile. “I wish for you to kill me my lord.”
A silence prevailed as Harry and Narcissa digested her words. It was his blonde lover who regained her senses first.
“Bella- I don’t-“
“It’s simple Cissy. The house of Black is indebted to him through mine and Reg’s oaths, ironic since he is now the Lord Black but then again I don’t believe magic really cares. I have already shamed the Black name enough, I don’t want this debt to curse future generations of our house. With my death, it will cleanse the slate and the future children of our house… your children, Andy’s children… will be free.”
-
“She want’s you to what?!” Kingsley exclaimed.
Harry rubbed his temples to alleviate the building headache. “Kill her, preferably brutally. She says the harsher it is, the better chance of it fulfilling the debt at least according to her calculations.”
The minister snorted, “Her calculations! We’re supposed to trust the Arithmancy of a raving lunatic?!”
“She did almost have her mastery in the subject before she became a Death Eater.” Narcissa stated quietly.
“Oh well that just makes everything better!” Kingsley bit back sarcastically. “Harry, I can’t just let you murder someone, even if she is a maniacal killer.”
“It’s not your decision minister. Magic claimed her life as forfeit the second she swore her allegiance. Now it’s up to Harry on what to do with it.”
“Wouldn’t it apply to the Lestrange line though, not the Black’s?” He questioned.
Harry shook his head. “She married Lestrange after becoming a Death Eater. Voldemort’s orders apparently.”
The dark skinned man deflated a little. He slumped back in his desk chair in defeat before gesturing to Harry. “Can we even trust her words though? Arithmancy mastery or no, her mental well being isn’t exactly sound.”
Harry nodded. “Even without the oath, she couldn’t lie to me if she wanted to. She explained it to us. Said that Voldemort bound her soul to him and that because of that she took on some of his traits. When I killed him, it transferred to me as part of the ancient law. It’s why she’s so… sane now. Her soul has bound itself to my magic and my magic healed her somewhat.”
Kingsley rubbed his chin in thought, mind racing through all the scenarios. Finally the older wizard sighed and leveled Harry with a concerned gaze. “Could you do it Harry? Ancient laws aside, could you kill someone in cold blood? Even someone like her?”
Harry stared back at the man. Could he? On paper it was simple. She’s killed hundreds in maniacal glee so surely ending her wicked existence was just. But that was much easier said than done. Harry had killed yes. Not just Voldemort, but other Death Eaters and Snatchers during the many months he, Ron, and Hermione.  Only in self defense though! Never for pleasure, spite, or revenge. But this was different right?
His eyes flicked over to Narcissa. Ever since they left the meeting room, the blonde had been reserved. Unfocused. He knew why. It wasn’t exactly easy sitting across from your sister as she begged for death, especially when it was her lover who would be the executioner. 
He took in the sight of her down cast eyes and shaking hands. The image stabbing something deep within his heart. When he had grew to care for the woman he knew not, but it mattered little now. His mind was made up.
-
Bellatrix looked up as the door creaked open and Harry Potter stepped in. He was followed by two aurors clad in their deep red robes. Her lord’s face was set in a grim visage. Fear pierced her heart as she realized what that look meant.  He had made his decision.
She fought off the tremble that threatened to course through her body. She had wanted this. Fear of death was natural, it was expected. This needed to happen.
The cage front of her cage was opened by the two aurors, one flanking each side of her cell. Bellatrix locked eyes with the man in front of her as he raised his wand.
“One last request my lord if I may? After it’s done, could you have my marriage to Rodolphus annulled? If I am to die I wish to die a Black.”
Harry remained silent. Bellatrix slumped in defeat and took a breath. “Okay then. Let’s get this over with.”
She shut her eyes tight, awaiting the spell that would take her life. Would it hurt? Would he draw it out? For how long? Minutes? Hours? Days-
Her thoughts were cut off by her arms being jerked forward. A gasp left her lips as she was suddenly pulled to her feet. Her eyes flew open and looked around. The chains across her body repositioned until she could stand comfortably. Her hands were now bound together behind her back and a chain wrapped around her ankles leaving enough slack for her to take small steps.
Looking up, she leveled her would-be-killer with a confused gaze.
“My lord I-“
Harry pierced her with an intense glare, silencing her words. “I will not kill the sister of someone I lo- care for.” He corrected. “But that doesn’t mean your debt can’t be repayed another way. You’ll still spend the rest of your days locked away, but under my supervision. Every day you will research and create ways to help and protect the innocent. Your proficiency in Runes and Arithmancy will be used to prevent anyone else from suffering at the hands of someone like you. You will die, but only after you have paid back the debt you owe to society first.”
“But the oath to House Black-“
“I AM HOUSE BLACK! And if I can command the oaths of the every other dark family then I command the one for our house as well! The debt is paid!”
As if magic itself heard his command, a pulse of light radiated out from the man. Bellatrix was hit with an overwhelming sensation, one that made her body scream out in obedience. She flinched as she felt the collar around her neck shrink and reform. Instead of the bulky metal hinderance she was used to, it now transformed into a simple bronze colored silk band. Blue runes still crisscrossed its surface, but now it was also adorned with a midnight black charm of the Deathly Hallows.
Harry didn’t comment on the sudden change. Instead, he simply waved his hand, summoning her towards him in a moment.
“Remember your orders and stick to the official story. I came back, killed her and left. Her body was incinerated along with any trace of her existence.” He said to the two aurors. Both of the stoic individuals nodded back, barely even gracing her with a glance. 
With that, Bellatrix Lestrange was dead, and Bellatrix Black was reborn.
