Harry’s life has changed drastically. He never thought this was something that could ever happen. Ever since his first year, Harry has been a slave to the centaurs, and no one even knows it. From what Lord Bane liked to brag about, Headmaster Dumbledore believes that Harry either died during the explosion that happened when he met the one that was killing the unicorns. Or he was taken by someone called Voldemort. And Lord Bane long proclaimed that they, the centaurs, will keep it like that. No outsider will find him, so he will be able to fulfill his “true purpose” without issue.

And what was that purpose? To be a broodmare for the herd. Apparently magical humans, male and female, could get pregnant from magical creatures. But that wouldn’t be it, oh no, see the centaurs were able to communicate with other hooved magical creatures, and Harry would be used to help rebuild those creature’s numbers as well. But first he needed to be trained.

Training wasn’t hard for Harry. Just really, really painful at first. Harry was quickly stripped naked, and then cleaned of “useless human trash,” which was the smell and feeling of soaps and other products. When that was done, they led him to the middle of the village. They measured everything about him, from his height, how long his limbs were, and even how big his penis and balls were. With that, they made what they called the Mare’s Bench. It was a big wooden cylinder, with a hole close to one end, that connected to a small tunnel that went out the other end. The whole thing was covered and fitted with pelts and leathers, and stood on a bunch of sturdy wooden legs.

They quickly put Harry onto the thing. He fit perfectly on it, and it was pretty comfy. The hole was for his genitals to go into, and they fit quite snuggly. Taking his arms and legs, they tied him to some of the wooden legs and then secured the Bench in the middle of the village. As he laid on it, Harry noticed that his head rested slightly off it, while his butt rested right on one end, and his cheeks were permanently spread, showing off his hole. Then came the pain.

He felt as a cold liquid was coated onto his hole, and then the body of a centaur rested lightly onto his back. Then something fleshy pushed against his butthole, and opened and stretched him up. The pain of it seared through Harry’s body instantly, and he couldn’t do or say anything. Whatever bound him to the centaurs made it so they commanded his body, and they didn’t want his screams to fill the forest, so he was made to be quiet the entire time. He felt as what had to be a meter long, bottle thick rod filled his butthole. Lord Bane stood next to his head and simply stated, “Your training will take a while. Eventually, you will be able to take the entirety of our cocks easily, and readily.”

The centaur on him started moving, and he felt as, what was apparently his penis, started to pull out, and push back into him. When Harry loosened slightly, he started really going at it. The centaur cock began pistoning his hole so fast and hard, magnifying Harry’s pain, until he stopped. He felt as a heavy and fast torrent of liquid filled him as the cock twitched in him. Then, as if the torrent pushed it out, the cock pulled out, and the centaur on him got off him. But that wasn’t the end. Soon, he felt another centaur lay atop him, and another cock was filling him, only this time there was no slow beginning. They immediately set a similarly brutal pace before filling him with that same liquid. Then another, and another.

After the eighth centaur, Lord Bane moved and displayed his cock for Harry to see, “See this human? This is what you are serving. This is your job for the rest of your life.” With that proclamation, Lord Bane brought the cock’s tip against his lips. With a command, Harry was forced to open his mouth wide, and felt as the centaur cock slid against his tongue, and rested in his mouth, “Lick and pleasure me human, this hole needs training as well.”

So as centaur after centaur pounded and filled his butt with a liquid, that he hoped wasn’t piss, he had to suck, lick and massage Lord Bane’s cock with his mouth. All the while, Harry got a good look at the centaur’s penis. It was easily a meter long, maybe even longer, and it was thick. He could barely wrap his lips around the thing. He discovered with his tongue that the cock had a flared tip, and a really big slit. As his eyes wandered, he noticed the huge, apple sized balls. But that wasn’t the main thing that drew his attention to them, it was that they started pulsing, and then the cock in his mouth followed. Lord Bane simply said, “Swallow,” and suddenly his mouth was similarly flooded like his butt. The liquid was insanely salty, but he didn’t have time to think on it, as his body obeyed, and as the torrent of liquid shot streamed from the cock, he was swallowing what felt like liters of it. It wasn’t piss, and for that Harry was happy.

“Enjoy that human, our cum will be your main drink from now on,” Lord Bane said, before he pushed forward and wiped the end of his cock against Harry’s outstretched tongue, making him lick up the left cum that was dripping from the slit.

Harry’s first month was them “training” him, and that meant getting pounded by centaur cock everyday. As each day ended, they would give him a potion, before having him wash it down with cum, usually directly from the centaurs’ cocks. Lord Bane explained that the training wasn’t a good time to impregnate him, so the potion stopped him from conceiving. When he was done training, they would stop feeding him the potion.

But his training soon ended, and Lord Bane declared that Harry’s first duty would be helping the unicorns' depleted numbers. So Harry was quickly drained of the gallons of centaur cum that they filled him with, and washed. Unicorns preferred a cleaned Mare, Lord Bane said. When the preparations were done, they set Harry out near the village, and waited. It didn’t take long. They unicorns came with a centaur escort, and quickly set to work.

For a week straight, Harry was pounded, filled, and used by the beautiful creatures. The centaurs were able to somehow convince them to also fuck Harry’s mouth at one point. So Harry even got a really good look at the creatures, and somehow, even their huge cocks were beautifully… pure was the only word he could think of. When they came, it was like drinking a sweet nectar, and the torrent that came from the horse cocks felt so good in his throat and butthole. The feeling scared Harry. If that was a side effect of their cum, then he might get addicted to it. Especially if he is going to be having unicorn foals for the foreseeable future.

Once that week was done, Harry was finally, after a full month locked in the Bench, released from it. He couldn’t walk at all, and simply was laid down on a bed of pelts outside the village, but it was nice not being tied to that Bench. But the purpose wasn’t a generous one. Harry needed to be near the unicorns so that the foal in him passively absorbed their magic, and they didn’t want to risk the baby by keeping him locked and ready to be fucked. Unicorns, while intelligent enough to communicate with the centaurs, are still animals. The hormones that Harry would be releasing would make the creatures want to fuck him, and they didn’t want to fight the creatures, and potentially hurt them, to get them out of his hole.

So for the next three months, Harry would sit out on the pelts, and have the unicorns be near him. Halfway through, Harry had to suck and service the creatures’ cocks as they constantly succumbed to the hormones of Harry’s pregnancy. It was the only way to keep them from accidentally hurting him by trying to mount him. Lord Bane said that the pregnancy would only last three months, as his passive magic, and that of the unicorns’, would speed it up. Normally, they are pregnant for seven months, but human magic is “good for some things after all,” according to the centaur.

Soon, the centaurs helped Harry deliver a healthy golden unicorn foal. It was a beautiful creature, and Lord Bane said that, since unicorns are so pure, even if they breed with humans, they only father more unicorns. They let him rest for three days, and then set him back into the Bench, and the cycle repeated. By the time Lord Bane was satisfied, Harry had birthed seven foals. That was twenty-one months of breeding and pregnancy straight. With twenty-one days of rest in total as well.

That was something Harry noticed a lot. Everything the centaurs did, and that magically happened, did so in sets of three or seven. Twenty-one was an important number, according to a few of the centaurs, but their reasons were about stars and such. Harry just thinks that if three and seven are magically important, then whatever magic makes that so, multiplies if you, well, multiply them together. But he doesn’t know, and probably never will. His education no longer pertains to learning much about magic, just about being a broodmare.

But one thing he did take away with all that was that he has been with the centaurs for nearly two years now. So he’s almost thirteen now. He doesn’t really know what month it is anymore. But he almost doesn’t want to know. Because if today is his birthday, he really doesn’t want to remember it being the day he birthed a unicorn as his belly was full of unicorn cum. As the end of his resting period neared, Lord Bane proclaimed what the next creature he would breed with would be.

A herd of Aethonans, a type of winged-horse, didn’t have any females, as they were killed by poachers. So Harry was going to be the substitute to help rebuild the herd. Instead of outside the village, they took him deep into the forest, where there was an open clearing. They set him down in the middle of the clearing, tied to the Bench once more, and waited. Harry couldn’t see much, but he saw the shadows fly by as they eventually landed. They landed near Lord Bane, and then came over to Harry.

Like the unicorns, they didn’t waste time, and immediately, Harry was being fucked by their huge horse cocks. By now, the pain has long subsided, and, embarrassingly, pleasure has become the norm as he was being fucked. It started midway through his time with the unicorns. He thinks the centaurs altered the Bench to make it happen, but they started smashing their long cocks against an area in his butt that made him see stars. As they fucked and came in him, they would constantly assault that spot, and Harry figured out what the tunnel connected to where they hid his genitals was for. As the animals fucked him, he eventually came himself, and his own cum would leak down the tube into a small pale. The centaurs said that human cum was useful for some potions and rituals they did.

Similar to the unicorns, Harry was pounded and bred for a full week, before being untied. As he was being moved from the Bench, he looked over and noticed that the pale was halfway full. That was a lot… well for him at least. Looking down, he noticed how numb his penis felt. But that didn’t matter, he had his duties. As he rested against the laid out pelts, he quietly watched the aethonans as they walked round him. Some rested next to him, and began nibbling and licking his hair and skin. Harry simply let them. Lord Bane said that they were grooming him, and making sure he wasn’t going to get sick because of bugs or such. They weren’t hurting him, so it was whatever to Harry.

Just like with unicorns, his hormones made the aethonans want to breed him once more, and Harry gently offered his mouth. Aeothonan cum tasted like the centaurs’, which was like drinking a diluted juice that had piles of salt dissolved into it. After one of the creatures shot some onto his face, and Harry quickly went to licking it up as it dripped down, he was proven right about before. He became almost addicted to the cum of the unicorns, and now he instinctively licks and swallows any cum near him. He knew there was something wrong when he registered that the centaur guards jeeringly laughed as he licked the cum off his hands. He was never commanded to do that.

But that didn’t matter. This cycle would be a full seven months. That was honestly worse than the short three months beforehand. It just gave him more time to think. But that didn’t mean his thoughts were… decent. In between swallowing aethonan cum, he would actually think about, and look forward to, the next one. How he liked the taste of horse cock. How he liked horse cum. How he liked the feeling of those huge balls as they slapped his face when they impaled their cocks down his throat. Then he would realize what he was thinking about and freak out even more. Then he was distracted by a horse cock. And the cycle continued constantly for seven months.

When it was time to give birth, it took a long time. And he knew it would. Before the delivery, his belly had gotten so big that he just knew it wasn’t one single foal. He was proven right as he birthed two. What surprised him was that one was, well, a centaur aethonan. He was so used to the unicorns, that he forgot that other creatures would make half-humans when breeding with him. He honestly never really thought about what a baby centaur would be like. Normal horse-like creatures’ foals immediately could walk around, but a centaur had a human half, and humans aren’t like that he knows.

However the centaur baby was able to move around like the others. He was more clingy to Harry than the other babies were, but it was more like his human half was already a year old. But that didn’t mean he didn’t not act like a young human baby. He latched instantly onto Harry’s nipples. Surprisingly to Harry, he felt as the baby actually pulled milk from them. The centaurs never touch them, and the other creatures obviously didn’t as well, that he didn’t know he could feed his babies.

As his, this time, seven day rest began, the centaurs actually didn’t try and take the baby away like he thought they would. They said that a young centaur needed its mother’s milk, as the magic in them was required for them to stay healthy. The baby would stay near Harry until he was around a year old. By then, he would no longer require his mother’s milk and he could then begin being raised.

As the rest ended, they pulled the baby away to the side, and tied him back up. In between being bred, they would milk Harry so the baby didn’t starve, they said, before a horse cock was pounding away in his butt once more. Harry went through two more pregnancies, once again resulting in a full twenty-one months of pregnancy, but he only had six foals in total, with two of them being centaurs aethonans, instead of the steady seven with the unicorns. Midway through his third pregnancy, his first foal, now named Cadmor, was taken back to the village and he was left with his second centaur baby.

Harry was glad they actually let him name the baby. He had to pick a name they approved of, but he got to pick it. But he was able to come up with the name for the younger one himself. He was little Chiron, after the Greek legend, and Lord Bane approved it. When he learned where Harry came up with it, he simply said, “See, even your ancestors knew centaurs were better.” Harry was pretty sure that’s not what the story was about, but if Lord Bane thinks that then he’s probably right.

As they returned to the centaur village, Harry was able to really look at his babies, without the distraction of cocks and cum. They were certainly unique among the centaurs. They’re coats were a beautiful chestnut brown, with pretty jet black wings. When he looked at their humanoid half, they took a lot from Harry. Their hair, while brown, was sticking up every which way. If they followed other centaurs, then those would grow into wild manes. They had pretty little jade green eyes, but they got some from their sires, as the golden yellow of the aethonans streak in between the green. The centaurs decided to wait for Chiron to outgrow Harry’s milk before breeding him once more so he had a few months to rest, although the horse cock plug to keep him loose and prepared was a bit uncomfortable.

As Harry quietly fed Chiron, he thought back to and quietly counted the time. Another twenty-one months, so that’s forty-two months, plus a month and a half for his resting, so about forty-four months. He’s been a broodmare for almost four years. Including his training time, and the time to feed Chiron, he’ll be fifteen when Chiron stops feeding. Harry wonders what he would have learned at Hogwarts by now. What he and his friends would have done together. All Harry knows of the going ons of Hogwarts is that Dumbledore is still Headmaster, and that the centaurs helped set things up for a tournament of some kind at some point. It was when he was being bred by the aethonans, quite literally, and the centaur guards were grumbling about it.

When Chiron was finally old enough, Harry’s next stallions would be another species of winged horse, called Abraxans. They brought him back to the same clearing, and set him back up like before. He expected something similar to the aethonans. He was mostly correct, with a pretty big difference. Literally. The creatures were bigger than the aethonans and the centaurs. Much bigger. And when Harry spotted their cocks, his body shivered in anticipation and fear. While similar in length, they were thicker than the others. If the other’s were like a bottle, then the abraxans were like a tankard. And it didn’t take long until they stomped over, and he was mounted quickly.

Harry was stretched even more than ever, and he’s ashamed to say it felt so good. They didn’t even need to try, and they constantly hit, slammed, and probably, broke his pleasure spot. Harry is pretty sure the cum pale had to be changed out he was cumming so much. Then they mounted his face. He could just barely wrap his mouth around that cock, and they didn’t even care. When he got the first taste of their cum, it reminded him of those drinks his uncle would have. Whisky he called it, but the abraxan cum didn’t make him gag like whisky made his uncle do, instead, it just made him want more.

Breeding with the huge stallions lasted a full two weeks instead of one. By the time Harry was laid onto the pelts, he was so tired, numb, and cummed out, that he honestly just fell asleep instantly. When he woke, one of the stallions were already fucking his throat. The centaurs seemed to have set up a small stand for them to prop Harry against, and let the abraxans fuck his mouth while he slept. As he glanced at one of the guards as he guzzled down another load of cum, they simply said, “Abraxans need longer to impregnate, and are almost insatiable during your pregnancy.”

This one would be another seven month pregnancy as well. But he didn’t just constantly swallow around the huge cocks. No, abraxans are pretty vain about certain things. These ones, after fucking Harry’s mouth, would then sit there as Harry had to clean the cock and balls of the creature of any sweat or leftover cum. They actually wouldn’t let another come up to Harry until he was done. This was the first time Harry actually tasted, or even really touched, one of his many stallions’ balls. They were just like the rest of the creature, and it was like licking and sucking a whole orange into his mouth. If he didn’t do it right, they would buck forward so that their thick cocks would slap Harry.

The first pregnancy was just a single abraxan foal, and Harry rested, for the first time in the nearly eight months that started. He would rest for a week, and then onto the next breeding session. He always had to be actually pregnant for a total of twenty-one months, the centaurs said. And the breeding time didn’t count toward that. They said that the reason he was bred so much at once was because his magic needed the time to absorb the magic of the other creature, and then prepare his body for the pregnancy. He didn’t actually conceive until the last day of his breeding. Normally seven days was enough, but abraxans, being so big, needed fourteen. They simply jeered that he should be grateful he wasn’t breeding with Leucrottas yet.

By the time they got back to the village, Harry was so cum-drunk that he couldn’t even think straight. By the time his mind caught up, he realized he was lying on his pelts, and was feeding two centaur babies. Their human halves were similar to their aethonan brothers, but instead of brown, their hair was almost pure white, with little black specks going throughout, like someone sprinkled pepper into their hair. Their centaur coats were light brown, like caramel, and their wings were a beautiful white, but with those black specks once more. Their eyes were like rubies, with pieces of jade sprinkled throughout. They were both from his last pregnancy, so Harry would be resting for a full year feeding them.

Honestly, even if he grew addicted to the pleasure the abraxans gave him, he really needed the rest. As he shifted to feel around his ass, he was still gaping open. It was something that the centaurs, especially Lord Bane, took great pleasure in seeing. “It’s proof you are a well used Broodmare, and are still breeding,” Lord Bane would say, and then would reach down to finger him. Well, Harry says finger, but really, he just shoves his whole hand into Harry’s hole. It accomplished the same really. He probably wouldn’t even feel just a finger.

Harry has been breeding for nearly six years now. He’s either seventeen already, or nearly is. Looking over to his first two centaur children, he smiles. It’s not in joy. It’s a mocking smile, directed at himself. By now, Chiron and Cadmor are over four years old, but they might as well look like teenagers. And they look so much like Harry. Cadmor looks the most like Harry, as Chiron’s hair eventually turned from the dark brown it was, to a gentle orange. Something he inherited from Harry’s own mother. Oh but that’s where the similarities stop sadly. They have been raised as centaurs of Lord Bane’s herd. So they think and talk like the rest of the herd. Although they do seem to have a small soft spot for Harry… but that doesn’t stop them from asking Lord Bane if they will get a chance to fuck the Broodmare next.

As the year passes and he’s no longer feeding his youngest, now named Raltos and Apep, Harry simply watches as they are led over to the teachers and seers. Lord Bane came over, and declared what was next. It was the unicorns once more, instead of a different species. It’s been long enough that they can support more foals now. But also because the properties of unicorn cum will help prepare Harry for his next stallions- the centaurs themselves. But more specially, Lord Bane himself. After Harry’s done breeding with the unicorns, Lord Bane will be Harry’s next stallion. “Your quality as a Broodmare has been proven more than enough, and I have deemed you worthy of mothering my children,” he said as Harry was tied up to the Bench and led out to where the unicorns would breed him.

His time with the unicorns was just like the first time, and was a strange change from the rough and demanding nature of the abraxans. It honestly felt like it went by pretty fast. He had birthed seven more unicorn foals, and they went off once more. After a short rest, Lord Bane came up to him. Instead of the Bench, they designed a hanging harness of some kind, and the centaur leader was wearing it. They quickly maneuvered Harry into it, and once he was settled, Lord Bane’s cock instantly penetrated his hole and simply rested in him. Then the centaur started walking around. As he walked around and did his duties as the leader of his herd, the movement would force his cock into and out of Harry constantly.

For a month straight, Harry simply laid in the harness, and was just a living cock sleeve for Lord Bane. The setup made it so Harry never knew when the cock would begin fucking him, or when the centaur came. It was seemingly at random times where the centaur leader would suddenly unleash torrents of his cum into Harry. It could happen while he’s simply doing errands around the village, while he’s hunting, or even while he’s sleeping, as the centaur, Harry learned, moved a lot in his sleep. But it didn’t end there. Oh no, Lord Bane had one last humiliation he wanted to do personally.

One day, Lord Bane had a special ceremonial cloak-like covering put onto him. It was long enough that it covered the entire horse-half of the centaur, all the way down to just above his hooves. So it also completely covered Harry up as well. Then he and a few others left the village, and galloped out to some unknown location. Lord Bane must have practiced running in this cloak a lot, as he never missed a step, which meant the entire time, Harry was being brutally fucked the entire ride. The centaur leader came into Harry twice on the way to where they were going, before they came to a stop. The centaur shifted, and hand reached down and calmly inserted a smooth plug into Harry’s mouth, with a command, “Be quiet, and don’t move.”

What followed a quiet wait, with Lord Bane simply pacing around, softly thrusting his cock into Harry’s hole. Just as the centaur unleashed one more torrent of cum, Harry heard the loud cracks echo from in front of them. Lord Bane started talking, and soon, Harry realized that he was talking to humans. And not just any humans either. No, this was a voice he remembers from long ago. It was Hermione.

She was reading from what sounded like a script, until they soon just started talking. The entire time, Lord Bane was pacing around, acting as though everything was annoying him, but Harry knew that was just an act. When Lord Bane was annoyed or mad, you could tell, and this wasn’t what ever did. No this was just to constantly fuck his cock sleeve, Harry.

Hermione sounded so much older now… which makes sense Harry guesses, but it was still surprising. She got a job at the Ministry it sounds like, and is working to improve human-creature relations. That sounded nice. Something she would get behind. Harry wonders if she would still believe in that goal, if they knew what they have been doing to Harry this entire time. What they have turned him into. Lord Bane stops pacing and saunters over to some different spot, and Harry hears the sound of a quill scratching parchment. With a satisfied sound, the centaur says something to Hermione, and cums once more into Harry.

That went on for what felt like hours. Harry soon knew the meeting was done as the horse cock started really pounding him as Lord Bane galloped back to the village. Halfway there, the covering was taken off. In the middle of the forest, they took the plug from Harry’s mouth, and simply re-maneuvered him so that Harry’s throat was full of horse cock. The plug was simply placed into his hole. “How’s it feel to know I can breed you right there, in front of other humans, and they will never know? That is your place forever now, being a Mare to any stallion I wish,” Lord Bane proclaimed. All Harry could do was simply gag around the cock fucking his throat, as they began galloping once more.
