If you had told Hermione on her first day of school that the dorky kid with the big, round glasses would be the man she'd enthusiastically want to have children with, she'd probably wonder where her life went so wrong. Growing up beside him, however, Harry had not only become more handsome, but his sheepish tendencies had made way for a brimming self-confidence. The man had wooed her without even trying, and when the time came that they actually made love, she embraced him. Instead of responsibly using the contraceptive like she was supposed to, Hermione fell in love with those gorgeous, green eyes and fully accepted his seed.
She prayed that it would take root, that he would be the one to make her a mother. Obviously, she still had her highly prestigious career in mind, but Harry absolutely had to be apart of her life from now on. Imagine her surprise when, the very day after announcing her pregnancy, he straight-up proposed. Hermione could not have been more ecstatic, Harry was perfect and he was all her's. She listened intently as he laid out his promise to cease all sexual activities with anyone else but her. He was going to be a one-woman man from now on, and as soon as they finished school, the first thing on his mind would be planning their wedding.
The first week, Hermione was aglow. While she was still technically pregnant, the magical charm within and around the castle ensured that any inseminations of the students or teachers would not progress past the cellular state. The baby's conception would frozen in time until she were to leave school grounds. Pregnant, but without any of the signs. Even so, the thought of her carrying Harry's child all that time filled her with perverse excitement.
Conversely, Hermione couldn't help but notice Harry started to behave a little strange as the week went on. Ever since he had devoted himself to her, he's been acting reserved around other women, nothing that would be too noticeable if you didn't know Harry. He was reigning himself in, intentionally trying not to be forward on anything. Those timid emotions from way back when were starting to resurface. Hermione couldn't figure out what the problem was until it hit her at Health Class.
Nothing went wrong. Harry acted like a professional and did his job laying the pipe inside Nymphadora Tonks, but the issue became all too clear. While he was still balls deep like his assistant title required, he seemed to be less enthusiastic about it. Hermione could tell by the look in his eyes he was thinking about her the whole time, quickly glancing over to her every few seconds to gauge any changes in her expression, checking her approval. The man was afraid of breaking his promise to his finance. Harry was sincere about wanting to be the perfect husband, even if it meant constantly second guessing himself.
Right then and there, she knew this could not stand. The man she loved was a ferocious beast, a sexual lion that delighted in making witches squeal their hearts out, and she was going to get him back no matter what. Hermione puzzled and puzzled over how to fix the situation, but in the end, the solution was crystal clear.
Harry walked through the hall towards the Room of Requirement, having been summoned there by Hermione for "an enlightening experience." The chamber which once held the preparations for war now contained one very frisky witch in need of a randy wizard's company. The boy made his way to the door and gave it a hardy knock. Hearing no answer, he cracked the door open, having decided to let himself in. Once inside, he saw nothing but violet mist and rolling waves of lavender haze. The smell was intoxicating and instantly sent a surge of energy into his groin the instant it entered his nostrils. Swimming through the fuck fog, Harry's vision began to clear as he got closer to a large shape that slowly solidified into a bed.
On the bed lied a very naked Hermione on her side looking up at him with a very sultry stare. "I thought we'd gone long enough without a little consummation," she said, "And besides, you seemed to be a little confused as of late."
Harry spoke up, "I swear, Tonks and I don't have anything going on outside the classroom. We're strictly professional."
"Oh, I know," teased Hermione, "And that's the problem." She rolled over and stood on her knees, "See, the thing is, I think you do want things to happen between you and the other girls, but you're too darn noble to embrace your instincts." Hermione snapped her fingers and a previously unseen door behind Harry opened with a loud creak. He turned around to see, of all people, Luna Lovegood waiting in a cubby for her cue.
The breathtakingly beautiful witch was completely naked as well and gave him an adorable wave, "Hello Harry." She dutifully skipped over to the bed and hung her body off one of the long bedposts.
"What is this?", he asked.
"This is my olive branch," she said, "I know you think being a faithful husband is about maintaining chastity around others, but I think it's much more fun being untethered to a single person, which is why I asked Luna to join us and make it official."
Luna piped in, "It's actually well-known that quite a few male animal species take multiple female partners at a time, so it's hardly unprecedented."
Harry couldn't believe what he was hearing, did Hermione really want to see him ravage Luna and completely ignore his solemn vow. In the muggle world, Harry knew that a promise between man and wife was sacred, and the first person to break that promise was undeniably the one in the wrong. A whirlwind of doubts swirled in his mind and made him speechless.
"I thought you might be a little hesitant," Hermione gleamed, "So I thought I'd start with an ice-breaker." She leaned over on the bed and grabbed her wand. Flicking it, a chair materialized behind Harry. "Sit down," she insisted. Harry, still a little confused, did as she commanded and sat in the chair. Turning towards Luna, Hermione took her by the hand and led her to the middle of the bed. Keeping her eyes locked on him, she opened her mouth and pulled Luna into a passionate kiss. The seams of Harry's trousers began to stretch as he grew impossibly erect. He watched on bated breath as the two girls' tongues danced inside their mouths.
One of Hermione's hands slid down Luna's slender back and grabbed hold of her pert rump. The kiss came so naturally even though neither women had shown any sign of bisexuality in the past. Prior to this, Hermione was afraid she might freeze up when the time came to actually do the deed, but being so close to someone so beautiful made her forget herself easily. Luna, on the other hand, had much less of an internal struggle with going full homo, as she had already done extensive research of the homosexual patterns in rams and penguins and had come to the scientific conclusion that all mammals were a little bit gay.
Breaking off the kiss, Hermione laid back on the bed and rested Luna on top. They proceeded to play with each other's bodies, fondling their breasts, feeling each other's skin. Luna's butt was bent high into the air, forcing Harry to contain himself as he watched. The white-haired witch felt a quaking in her nethers followed by a dampness accumulating between her legs. "Can Harry join us now?", she asked.
"No," said Hermione, "Not until we've finished." Entangling their legs, Hermione began to grind her vagina into Luna's. It was a little clumsy at first, but with patience, they found a rhythm that pleased their bodies. Hermione was becoming damp, the slickness of their pussies losing friction over time. Their lower lips meshed together, furiously making out with it each other. The girls could feel climax was rapidly approaching, but neither resisted the coming tide. Slowing down now would only dull the the finish. Hermione looked into Luna's eyes and reached her hand out. Luna grabbed hold and entwined their fingers, gripping her partner as hard as she could.
In no time at all, the girls came, wailing like banshees for none but Harry to hear. They fell limp on the bed in post-coital bliss, both practically glowing. Harry got out of his chair and approached the bed, "Hermione, what does any of this prove about our relationship?"
"You're a wild stallion, Harry Potter," claimed Luna, "A beast who is most beautiful when free. Neither I nor her wish to see you holding back any longer. It would be a great tragedy for your limitless virility to go to waste on just one woman."
"Couldn't have said it better," Hermione piped in, "Harry, I'm turning down your marriage proposal."
"What?", cried Harry, "But what about our child?"
"Oh, don't worry. I still intend for us to be parents, just not out of wedlock," she said, "If we are to be together, it should be because we still love each other, not out of some sense of obligation. Think about it, if your life weren't tied down by a ring, you would be free to entrance any witch you desire without scarfing your morals."
"Hermione," he said, "Be reasonable."
"I am being reasonable," she snapped back, "Matrimony is an outdated construct anyway. No one would bat an eye if they learned Harry Potter had a harem."
"And what's more," said Luna, "I wish to join you."
Harry chuckled, "Are you serious?"
"Yes, ever since our encounter in the Forbidden Forest, I have been very interested in having your child," she said.
"Oh no," teased Hermione, "It seems you've accidentally caused a beautiful young woman to fall in love with you. You wouldn't want to disappoint her, would you? Especially when there's babies to be made."
With that last statement, the unholy tent that Harry had been pitching in his pants suddenly burst free, ripping a clean, circular hole right through his boxers. The man now had a make-shift glory-hole built into his jeans. Slowly inching forward, he whispered to Luna, "Are you sure about this?"
She held his face and said, "You are my mate, I refuse to take anyone else."
Any hesitation Harry had a second ago was long gone now. Hermione felt it would help the mood if they were both unclothed and so she apparated his destroyed pants away, leaving Harry starkly nude. He wrapped his hand behind Luna's head and pulled her in for a deep kiss. The two had done this before, but things were different. A new kind of rush surged through their bodies, they were actually going to do it. They weren't having sex just for the fun of it, they were doing it with purpose. Nature was taking it's course, their bodies were doing what they were build for.
Harry could hardly contain himself, his penis twitching with excitement. Aside from Tonks, which was curricular, this was the first time he would make love knowing it would result in a child. He wanted to see it, he wanted to see Luna's belly swell and grow all because of him. He wanted to see Luna bloom into a more radiant goddess; an adult, a mother, a woman. Harry couldn't contain himself any longer, he grabbed her waist with both hands and began shoving his way inside her vagina. The slow crawl to the finish was grueling, mercilessly sliding all the way to the hilt before stopping at her womb. He looked into her positively beaming eyes and started thrusting.
Luna's depths were as silky smooth as her hair. Her insides wrapped around his cock lovingly, tendering milking his release. She wanted his baby badly. Ever since Hermione had announced her pregnancy, Luna had fantasized herself in that role. She imagined being rutted day in and day out by her beloved mate, producing young after young for the rest of their days. When Hermione came to her with the proposal, she was ecstatic to join their circle. It might not have been exactly how she'd envisioned it, but the idea of being one of a sprawling harem wasn't a bad existence in her mind.
Her breath ran ragged, holding on to her composure for dear life. She was desperate not to immediately cum, but Harry certainly wasn't making it easy. At the same time, Harry was in a similar predicament. Her tits hypnotized him, her moans of passion tempted him. The strength and resolve he used to defeat his enemies in the past paled in comparison to the stamina he needed to not instantly nut inside Luna Lovegood. He could feel his balls tightening, readying themselves for one fateful blast.
Luna could see the struggle in Harry's face, the contest of wills. She pulled him close and whispered in his ear, "Don't fight it, don't resist. Can't you feel it? Our child wants to be born. Let's let it happen, let's make…our little one…NOOOOOWWWWW!"
And with that, Harry gave a mighty roar, releasing all of his seed inside of Luna. The girl was ecstatic, her chest heaving from exhaustion as sweat rolled off her body. She let Harry lay on top of her for a spell before giving him a slight push to lay beside her. His cock dislodged and a river of cum leaked out of pussy, staining the sheets. Without a doubt, she knew his cute, little swimmers were working their way through her right now. Luna placed a gracious hand on her flat stomach and envisioned the moment when his sperm would reach her egg and inseminate her. She flopped on the bed and smiled, knowing her fate was sealed.
Hermione sat on the bed next to Harry and fondled his spent balls with love and devotion. "You see, we can be more than just a nuclear family," she said.
Coming down from the sex, Harry weakly asked, "So, what, you want me to start sowing wild oats?"
"What can I say, I love to see you work," said Hermione, snuggling beside him on the bed, "Especially since there seems to be nothing that turns you on more than the idea of knocking someone up."
It was true. The surge of emotion, the lose of his inhibitions, Harry had an intense desire to breed. Perhaps it was his sense of isolation as a child, desperately wanting a real family of his own. "Do you think the Wizarding World will really accept this version of me?", he asked.
"You're Harry friggin' Potter, if anyone deserves to leave behind a massive family tree, it's you," Hermione stated, "I highly doubt there'll be anyone would object to the Chosen One fathering an entire generation of wizards. It's almost expected, even."
"And besides," added Luna, "It's not like you wouldn't be able to afford it. You're rich now, remember."
Harry thought back to how Serious Black's passing ensured that his entire estate and fortune went to him. He couldn't believe, this could actually work. Harry pictured in his head an entire gaggle of beautiful women enjoying themselves, happy to be around him. He imagined the tidal wave of toddlers rushing toward him begging for piggy-back rides, watching them grow up and become their own people. A sense of fatherly pride swelled up inside him. The man snaked arms around both ladies' waists and pulled them in tight, making a witch sandwich. He looked at both girls and said, "Okay, if you girls believe we can do this, I'll give it my all."
Luna wrapped her arms around his collar from behind, "The Coven of Harry Potter. I can't wait to see you'll join us next."
