Breeding stock

After the war Harry Potter went to the bank and found he was the head of four noble houses. He made Teddy his heir for the Black but for his other houses he needed heirs. The goblins said he could have a wife for each house if he wanted or he could marry one woman she can have the three heirs. Harry spent hours in his library thinking of the lucky witch that would give him his family.

His first choice was Hermione and a major part of that was because they had lost their virginities together on the run. While it was good she was very prudish and now with Ron. If he professed his love for her she would run into his arms but it would ruin his friendships.

Next was Daphne Greengrass. He always thought she was beautiful in class. They shared a couple of moments in school being partners in class. She would get close enough he could smell her shampoo. As far as he knew she was still single. He thought he could see their future together. A complete power couple together they could rule the wizarding world. She was a solid prospect but he needed heirs now before someone gets lucky and kills him.

Susan Bones was another girl he could see a future with. Only problem is that she wanted to follow her aunt's footsteps and would have no time raising a family.

'Could I pay a surrogate? But half of the DNA could be weak. No, I need a strong witch.' His mind kept searching for names until he came upon Narcissa Malfoy. No matter how much he hates Draco he had to admit he was a formidable wizard. She owes me for keeping her and Draco out of Azkaban. He didn't need to marry her, he just needed children.

His next mission was thinking of how to approach making Narcissa his broodmare. He searched the Black library searching for spells or potions that would help him in his mission. A simple impiro would work but it didn't feel right. He wanted to own her body and soul.

'Black Family Sex Tome' he pulled the book off the shelf and found Sirius had marked up the book. He left notes on which spells worked and the fun he had using them. One of the things marked 'Super Fun' was a potion that increased the amount of cum you produce and how fertile it is. Sirius had even sketched a bucket next to it making him chuckle. The next one was a bondage spell that tied the hands behind the back.

Close to the end of the book there was a page dedicated to how pureblood women weren't known for having lots of kids normally two was the max. Also most pureblood women hot less interested in sex the older they got so this adphrodisiac increased their fertility and made women insatiable. Three drops into her tea and it will turn them into a Knock turn alley whore. 'Perfect now to send her an invitation.'

Malfoy Manor

Narcissa was in her dining room as Draco and Astoria Greengrass were upstairs doing Merlin knows what. After she read the Prophet she went through her mail and came upon a letter from Harry Potter sealed with the Black ring.

Dear Narcissa

I wanted to have a conversation at your earliest convenience. It will concern your family's future. I would have this conversation with Draco but I don't want to hurt him. We will be meeting at your childhood home floo over tonight at six . I look forward to your visit.

Love

Harry

'That is a really familiar end to a letter. He seems like a nice young man, maybe he ends every letter with love. I will have to give him some etiquette lessons so he doesn't embarrass my old house.' She needed to get ready; she hadn't left the house in two weeks. She went to her room and immediately ran a hot bath. As she scrubbed herself she thought of what she would wear. Normally Lucius would make her dress in dark colors like black and green. 'I have that red dress in the back of my closet.'

She stepped out of the bath and slipped into her robe. Walking over to the mirror she frowned. She was gaunt from months of stress and lack of sleep. She had lost some weight due to the war. 'Merlin it is going to take some time to get ready.'

Hours later

When she arrived at her childhood home Harry was sitting on the couch drinking fire whiskey. "Hello Mr. Potter."

Harry stood up and gave her a big smile, "Narcissa it's great to see you." He extended her arms and gave her a small hug. She was here in a beautiful red dress that showed off every curve.

When he pulled away her cheeks were red. "Mr. Potter...what did you want to talk to me about?" That hug caught her off guard and her body melted into his. 'Stay focused Narcissa he is just being nice must be his muggle upbringing.' Hard to believe he was the savior that beat the strongest dark wizard ever.

Harry could see her eyes look around nervously. "Let's go into the kitchen and talk. I have some snacks laid out for us."

She followed him to the kitchen and saw he had laid out a buffet of snacks and tea. He pulled out a chair for her like a gentleman and she graciously accepted. She was starving and eagerly picked up some biscuits to dip into her tea. "So what is it you need of me?" She was skeptical of this meeting what would the most powerful man in the world need with her.

Harry smiled, "I just wanted to touch base and see how you and Draco are doing." He could see her shoulders relax as she let out a big breath.

"He is currently shacked up with Astoria Greengrass and barely leaves the room. I have not left the house. I'm too afraid to go out without an escort."

Genuine sadness washed over Harry's face. "I am so sorry you shouldn't be afraid. You helped me save the world, everyone should be getting on their knees and thanking you."

She could not believe she was blushing so much in front of someone as young as her son. The thought of people getting on their knees thanking her gave her a thrill. "I did what it took to keep my family safe. I wanted to thank you for your kind words keeping us out of jail. I know you couldn't save my husband but I'm still grateful."

Harry could see that she was warming up to him. "Now that I am the head of the Black family I have anuled your marriage so you can get remarried if you want." He wanted to know if there was someone in her life before he went through his mission.

She let out a loud breath she didn't know she was holding. "You didn't need to do that." She took a long look into his emerald eyes and felt more peace than she has felt in months.

He reached over and put his hand on hers, "He is never getting out don't you want to be happy?"

She felt tears welling up, "Who would want me?" She had spent years being alone. When Draco wasn't home she spent days without seeing Lucius.

"You are a hero who wouldn't? Don't you want another chance at happiness?" He could see the hope enter her face. He could build her up to be what he needed of her. He needed a strong matriarch for his family.

'Just breathe in and out don't break in front of him. Be strong.' "Let's talk about something else. What is going on with you?" Why bore a hero with wife tales.

"I am the heir to four Noble houses and I need someone to start making heirs. I wanted to hear your opinion on the matter and to see what you would do." Now the trap was set he just had to walk her into it.

She put her finger to her chin in thought. "Four houses is a lot. I take it you are going to find a nice muggle born witch to have all those heirs with."

He shook his head, "I don't know what I am looking for. Hermione is out she is with my best friend and the other witches I'm looking at don't seem like large family girls." 'A little more and she will be ready.'

The wheels were turning in her head, "My son was always into Daphne Greengrass; it's part of the reason he is with her younger sister. I know most women would be happy to be your queen." It's amazing her son found anyone with his father's personality.

She was throwing off a couple subtle hints like pushing her breasts out and licking her lips. She wanted this He watched her finish her cup of tea and quickly refilled it this time with the sex potions. "I think I might want an older witch. Do you know any that would want a family?"

"No I don't. I don't think it would be hard to find someone if you put an ad in the prophet." She chuckled at her own joke and took a sip of tea. Instantly she felt different; she tried fanning herself with her hand. "That tea must have been too hot, I'm burning up."

He stood up and walked behind her and put his hands on her bare shoulders. "You are burning up, do you want to go lay down upstairs?" He could feel her shaking under his touch. Every movement made her moan and lean into his touch.

She was ultra sensitive and could feel herself losing control. His hands on her neck felt so good she couldn't think straight. 'Why am I feeling this way? I have never felt this turned on. I have never been this wet before.' She felt Harry take her into his arms and walk her upstairs to the master bedroom. She was already horny and could barely think straight anymore. 'Why am I about to cum just from being held?'

Harry laid her on the bed and used the bondage spell tying her hands behind her back. "What are you doing... to me? Why can't I control myself?"

Harry vanished her dress and everything she was wearing underneath. "You are mine now Narcissa. I need a woman who can give me heirs and I chose you. Don't you want another chance at being a mother? Don't you want me to worship you body and give you more orgasms than you can count"

She could barely hear him. She was just focusing on rubbing her legs together. "I...ungh...can't...take this please...fuck...me"

He pulled her legs apart, "I really overdid the potions but listen to me carefully. I am going to fuck multiple kids into you tonight and you are going to be my mistress. You will help me raise the kids and you will get a second chance at being a mother. I have used potions that will make you fertile and wanton. I promise you will enjoy this and after this day you will be protected." He let her legs go and got undressed. Her eyes roamed his body and he loved the look of fear when she saw his cock made him even harder. She started squirming again trying to speak but it was getting harder after seeing Harry's massive ten inch cock. Harry ties her legs to the bed posts and did a quick charm that removed her bush hair into the shape of a lighting bolt. "I made this permanent so you will always know who you belong to." She was gushing and as soon as he made contact with her pussy she came with a scream. Just the heat of his cock head on her clit made her cum harder than the strongest vibration charm on her wand.

When he entered her she was so tight he couldn't believe it. "Fuck you are tight I can't believe you had a kid. I hope it's still this tight after you have all my kids." Her pussy was convulsing around him making it hard for him to hold back his cum. He quickened his pace giving it to her as hard as he could. She had a blank look on her face, mouth open, eyes rolled back.

Narcissa was just moaning she was too far gone to form words. Her mind was almost going blank from the amount of pleasure. She could feel every vein, his cock punishing her cunt. She had cum so many times nothing was ever going to be the same. 'I hope this never stops. I can't live without this cock.'

It was nearly half an hour of him brutally fucking her before he downed a fertility potion. "I'm going to cum it's going to be more than you are used to." That was all the warning she had before he came buckets inside of her. His cock was pressed against her cervix depositing everything in her womb. She screamed in pure pleasure she had never felt so full in her life. It was also molten hot like she just stepped foot into a steaming hot bath.

He came so deep inside of her he could see the bulging of her stomach from all the cum. She looked three months pregnant already; he quickly transfigured a plug and inserted it as he pulled out. He cast a spell making sure it wouldn't come out on its own. "I will cast the pregnancy check spell in a little while and until then my cum isn't going anywhere."

The look on her face as Narcissa came over and over from pleasure. She looked down at her body and her eyes went wide at the site. She was so full and wanted to say something but no words came out. 'What is this? How can he cum so much?'

Harry was still hard and watching her writhing on the bed with her stomach full made him even harder. He climbed up her body and gave her breasts some love. He licked her nipple which was hard with her constantly moving. "You are so beautiful like this. Even when you are mine months pregnant I'm still going to fuck you. Do you like that?" He moved up even more and kissed her as he played with her clit. "I am pretty sure you are pregnant right now." He summoned the flushing potion and fed it to her. As she was coming out of it she was still shaking in ability to form words.

Ten minutes later she was able to form words again. "I can't stop cumming please take it out." Her belly was still full and he wouldn't stop fondling her body.

He stopped fondling her and undid the spell holding her hands behind her back, "Not until I know you are pregnant. Is there anything else I can do?"

As soon as her arms were free she rubbed her stomach. "You just wanted to get me pregnant?" She was struggling to understand what was going on; she was in sensory overload.

He rubbed her stomach with her, "Yes while we were talking I looked into your mind and saw you wanted to be a mother and that you were attracted to me."

She groaned, "Just because you peeked into my mind doesn't make this okay."

"When I annulled your marriage You are mine Narcissa...forever. You are the woman who I want to build my empire with."

Narcissa couldn't stop her body from craving his cock. "I don't care just please fuck me again."

Harry complied and flipped her over then pulled her to the edge of the bed so she was bent over the bed. Her pink unused little asshole was hidden in her perfect ass. "I am not going to compromise my children but I am happy to try this hole."

She didn't want to be turned on but she couldn't help it. The pressure on her stomach made her cry out, "Ah Harry." She felt his wand enter what she would call the wrong hole. He cast a spell that cleaned her and lubed her up. She had heard of this kind of sex from other witches but it is something she never tried. "I haven't done that before. You are too big for that."

He put all of his weight on her as he entered her tight ass. "You are doing great my little cum dumpster. I promise you will like this." He grabbed her asscheecks loving the feeling.

"Don't call me that. Ah not so rough." She felt him go all the way inside of her. "I can't take this."

Harry pulled her hair ,"Yes you can. You were made for me." When he said that he felt her tighten up around his cock. "I felt that you liked that? Did you like my cock tell me how much you love it."

She didn't want to but it started to feel good. His cock was pushing against her full womb. "Fine I like it just please take the plug out it's driving me crazy."

He tapped his wand against the plug and applied a vibrating charm. That made Narcissa scream and shake. "I'M CUMMING!" She felt like she was on the potion again and her vision was going white with pleasure. After she came she felt him push her head down into the bed and fuck her deeper and harder as he chased his orgasm. Every other thrust he was spanking her with enough force he left a print.

"I'm still on the cum potion Narcissa. Get ready." She didn't have a chance to tell him to pull out before he blew another hot load into her. He picked her up and walked her in front of the mirror while still inside of her. She watched her stomach grow even larger and looked into his eyes. He watched her fill with his seed. He waved his wand over her womb and saw four blue balls and one pink ball. "Congrats you are a mom again to five children. Get ready. For the finale." That's all he said before he pulled his cock out of her ass and pulled the plug from her cunt. All the cum he pumped in her body came rushing out made her legs weak. He held her up as a giant cum puddle formed beneath her. Just for that little extra humiliation he dropped her and she fell into the cum. She looked up at him surprised he would do that only for him to force his cock into her mouth. "I got one more in me."

She was still reeling from the cum leaving her body and let him fuck her face. He gripped her hair and fucked her face with vigor. Sucking cock was never her favorite but Harry fucked her throat in a way that got her off. She started rubbing her clit desperate to cum before he did. She didn't care she was sitting in a hot sticky cum she just wanted more. She couldn't help herself in wanting more.

Harry smiled looking down and seeing her look into his eyes with tears running down her face. "I'm almost there. Do you want to swallow it? Do you want me to pump your stomach full of hot cum?"

She quickly shook her head knowing if he did dump a gigantic load down her throat she would probably drown. He pulled out of her mouth and stroked a couple times before showering her in cum. She closed her eyes and felt every spurt land across her face. When he was done she opened her eyes and looked at Harry.

Her eyes were glassy and she was out of it," Just bring me to bed and we will talk in the morning." Before he brought her to bed he cast a cleaning charm on them and the bed. She passed out in pure exhaustion. He whispered in her ear, "Sleep well."

Epilogue

It took a couple days for the aphrodisiac potion to wear off. Every hour Narcissa needed to fuck Harry or else she would lose it. He was more than happy to ease her sexual suffering.

Narcissa moved into his place. She hadn't told Draco not wanting to have a blowout fight. He would find out when they were seen at the hospital and she was giving birth to all of his siblings. They had a long talk about her new role and she knew Harry would have to take a wife his own age but her children will be his heirs. The marriage would probably be loveless based on the amount of love he showed her. They had amazing chemistry and couldn't keep their hands off each other for more than a couple hours. Harry liked using her in every way possible and she couldn't resist. He was perfect and made her feel like a teenager again. He had unlimited stamina but thank Merlin he stopped cumming in large amounts. He kept saying as soon as she gave birth he was going to do the whole process again.

She had to tell him kids are a major responsibility and they would have to wait a couple years before they could do it again. That didn't stop him from trying more things from the Black Sex Tome. She hadn't minded the bondage rope suspension spell. Harry made every time feel like the first time.

In the last month of her pregnancy she was bedridden. Her stomach was so large and swollen from holding five children. She was lucky there were no health complications. Harry loved curling next to her and feeding from her breasts.

When she had her children she had never been so happy. Her daughter was born first and she was the most beautiful thing she has ever seen. A blonde haired little baby girl, she demanded full control in the naming process with her daughter. The name she settled on was Megara Potter.

The boys all had Harry's unruly black hair and green eyes.

Harry made it his mission to shape the wizarding world to his vision to create a future his children would be proud of.

End

Hope you liked it. I spent a lot of time with this concept trying to get it right. I love this pairing so much and I wish people did more of it.

I am also working on another fic where Harley is tied up for Batman and I'm trying to get that one right next.
