A Mare's Victory and Her New Brand
She ran her fingers over the muscles of my thighs and said, “Still firm. You’ve been training consistently, haven’t you? Very much like a champion mare.”
“Hehe, I train whenever I have the time.”
“Your breasts have shrunk a little. That’s good. They were so large they must have interfered with running. Have you stopped being a dairy cow? The tag no longer lists it.”
“Yes. Due to certain circumstances, I can’t continue as a dairy cow.”
The trainer lifted my breasts, checking their weight and condition. When she noticed the vanished Dracule pattern, she seemed to accept that there must be some unspeakable reason behind it.
“You mentioned earlier that it would be good to split the races into a first and second league, correct?”
“Yes. It would make management easier, allow us to hold second-league events and accommodate separate guests. Promoting high-performing mares from the second league to the first and demoting low performers from the first to the second would also boost motivation.”
“Hmm… The number of mares has been growing, and having them all race on the same day has become quite a burden. Splitting the race schedule would definitely help. I’ll inform the operations department.”
Jerry, who had been listening to our conversation, lost interest and lay down on the straw to rest.
The trainer continued her inspection. When her eyes reached my slightly parted pussy, she remarked, “Oh? You must have mated quite a lot. Your vagina is split open.”
“Yes. I have a Master now.”
“A Master? So you’ve found someone to serve. Invite him to the next mare race. I’m sure he’ll enjoy it.”
“Oh, that sounds good.”
Since my Master preferred strong females, he would surely be pleased to see me win. And if I earned his favor, it might prove useful later when I operated the human-horse arena in Eden.
“There’s a race in three days. Will you participate?”
“Will my body recover in time?”
“For you, Ellie, it should be possible.”
“Then I’ll do it.”
There was still time before Isabel fully became a symbiote, so spending three days here as a mare would be fine.
“Good. Let’s begin training immediately. Prepare this mare.”
The trainer left the android on standby to handle the preparations and went to gather her equipment. The android that approached me fitted me with a blindfold, a ball gag, and reins before leading me out of the stall.
The anticipation of running as a mare again sent a pleasant thrill through my heart. Following the pull of the reins, I arrived at the training track thick with the scent of mares’ sweat. Since training had just ended, the smell was especially strong. I loosened my body lightly.
Before, there had been a slight awkwardness because my ankles and feet hadn’t fully adapted, but now my body was perfectly adjusted to the high heels and felt completely comfortable. I practiced a more relaxed posture while waiting, and the trainer soon returned.
“Shall we warm up first? Let’s do an easy thirty laps.”
“Mmph.”
The trainer climbed into the practice carriage connected to my corset, cracked her whip, and pulled the reins. Crack!
I adjusted my direction according to the reins, found my position, and gradually increased my speed. As my pace rose, the nanobots activated and began producing pleasure substances.
Ugh. As expected, having pleasure substances injected directly into the brain was electrifying. Crack!
“Having trouble focusing since it’s been a while? Concentrate!”
Crack!
The fierce lashes brought me back to my senses, and I focused on running. The carriage surged forward with the powerful movement of my heated muscles. Becoming a succubus had clearly improved my muscle performance and efficiency. Even at the twentieth lap, my muscles still had energy to spare. Perhaps because I consumed essence, fatigue accumulated more slowly and my stamina was far superior. Crack!
“Your condition is excellent! Final ten laps at full speed!”
When I poured on the speed, my velocity shot up dramatically. Was I always this fast? Feeling the wind brush my sweat-drenched face, I completed the ten laps. As I slowly reduced my pace and stopped, the trainer spoke in a surprised voice.
“How did you get even faster? If you avoid accidents, winning will be easy.”
It was still inconvenient not being able to speak. Although preventing speech was part of being a mare, the communication issues suggested room for improvement.
After enjoying the pleasant ache in my leg muscles and the lingering pleasure substances that had heated my brain, I continued with detailed training. The trainer kept exclaiming in admiration as she watched me complete every exercise with ease.
“You’re truly incredible. How can such an outstanding mare exist? It’s overwhelming.”
“Mmm.”
“Would you like to breed and have a foal? With your bloodline, you’d produce an exceptional offspring.”
“Huff.”
She knew I couldn’t speak, yet she kept asking me questions. As the trainer stroked my lower belly and urged me to breed, I felt how the people here truly treated mares as animals. And I felt pleasure at being treated as one.
My womb trembled at the suggestion of breeding, but I couldn’t do it yet, so I shook my head. She looked disappointed.
“What a shame. Since you’re a free mare, I can’t force you to breed. Still, if you ever change your mind, please give birth. I’ll raise the foal well. Okay?”
“Mmm.”
When I nodded to indicate I would consider it, the trainer spoke in an excited voice.
“You promised? I’ll find an outstanding stallion, so come whenever you’re ready to give birth.”
It seemed the meaning had been slightly distorted, but since the final decision to have a child was mine, I let it pass.
Time flowed as I trained with the other mares while waiting for the race. Mares whose orgasms were restricted and who received constant pleasure injections suffered from severe sexual frustration. Jerry, receiving a massage beside me after training, was a skilled champion mare, yet she still let out moans as she endured.
The essence the mares emitted filled the surroundings with dazzling colors. As I absorbed the unique blend of various mares’ essence, their frustrated thoughts and desires flowed into me.
Mmm. Even though it was for the sake of the races, prohibiting orgasms while flooding them with pleasure seemed too cruel. Aside from breeding, they only received pleasure from caresses and drugs. From the moment one became a mare, real penetration was forbidden.
The mares’ lower bellies were thick with stagnant, condensed essence that was beginning to solidify. Although they were allowed orgasms after races, those were ultimately induced by drugs and petting. Unable to properly relieve their desires, the essence had grown viscous and sticky.
Returning to the stable, I discussed the issue with the trainer.
“So you’re saying their frustration is becoming a sickness?”
“Yes. Because their desires aren’t properly relieved and only accumulate, it will negatively affect their health.”
“But these measures are necessary to improve racing performance. They’ve proven effective.”
“At the very least, how about allowing mating after races to let them release their desires?”
To discharge accumulated essence, mating with a rational partner and a true orgasm were necessary. Orgasms without penetration were only a temporary measure and released very little essence.
“Who would want to mate with a mare?”
“My, you’re underestimating human sexual preferences. Since they look exactly like humans, there will be men who would gladly have sex with them.”
“Hmm. That’s true. Allowing mating once a week wouldn’t be bad. They’d train better if they could fully release once in a while, right?”
“Exactly.”
We also discussed how the mares should mate. In the end, since the owners existed, we decided to first ask their opinions and proceed accordingly.
The trainer stroked my head and said, “It’s kind of you to worry so much about the other slave mares. Other free mares only care about satisfying their own desires, but you’re different, Ellie. Is it because you were an angel?”
“We’re all mares. We should look after each other.”
After the trainer finished organizing the discussion points and left the stable, saying she would submit the suggestions to operations, Jerry asked me a question.
“Does this mean we can mate now too?”
“If it goes well, yes.”
“I hope it works out. Holding back has been too painful.”
The essence in Jerry’s womb was thick and sticky, heated and clumped together. The violently fluctuating essence beat against her womb, stimulating it.
Mmm. It really seemed that relief through mating was necessary. Contact between mares was also forbidden, so I couldn’t directly suck out their essence, and since it was only a temporary measure, regular mating was essential.
On the day of the race, the trainer, confident of victory, introduced me to an acquaintance she had invited. But was it really allowed for the trainer’s acquaintance to enter the stable? The lax security was surprising.
“This is the best mare I’ve raised. Her name is Ellie.”
“Wow~ She’s impressive. Her bone structure and musculature are excellent.”
“Don’t you think she’d produce a fine foal if bred with the stallion you raise?”
“A mating between two champions? Of course.”
Only then did I realize the woman was a stallion trainer. No wonder she could enter so freely—she was track staff.
She examined my body here and there as if appraising me, then inserted her fingers into my pussy, probing deep inside as she spoke.
“Wide pelvis and healthy reproductive organs. Good, I like her. When is her ovulation period?”
“This mare is a free mare. Although breeding permission has been granted, she still needs approval as a breeding mare, so we haven’t decided when she’ll give birth.”
“A free mare has been permitted to breed? That’s new to me.”
The two discussed ownership of the stallion and mare while I stood before them.
“Let’s agree that I’ll raise the mare and you’ll raise the stallion.”
“Just raise it together. It’ll need to focus solely on growth for the first year anyway. Training it during that time would be too much for one person.”
After discussing for a while, they eventually concluded on joint ownership. The perverse situation of another person owning the child I would bear excited me slightly.
After the breeding agreement was settled and race preparations completed, the event began. Having comfortably taken first place in the practice race the day before, I waited in the last position in a posture of submission.
The commentator’s calm yet rapid commentary mixed with the spectators’ cheers created a crucible of excitement. There seemed to be far more spectators than last time. In an era where the animal known as the horse, once used for carrying loads, had become rare due to scientific advancement, horse racing performed by attractive human-horses was bound to gain popularity quickly.
Even I, a mare myself, found the passionate races between attractive mares appealing. Who could dislike it?
When my turn came, I took my place at the starting line. In my heightened state before the race, I pawed the ground. The jockey holding my reins said,
“Now, let’s win again and prove your breeding value is high.”
“Huff.”
I simply wanted to run, but the trainer seemed completely focused on breeding me. Mmm. I hadn’t thought much about it before, but seeing how strongly she desired a foal from me made me feel I should properly give birth.
“Now! We will begin the top-tier race! Three!”
“Two!”
“One!”
Bang!
As the spectators’ countdown ended, a starting shot rang out and the jockeys’ whips began to fly. Crack!
“Run!”
Explosive power surged into my prepared muscles, and I shot forward at tremendous speed. I took the lead with a velocity that surprised even me. The commentator’s astonished cry reached me.
“Ah! Ellie takes the lead with overwhelming speed! The other racehorses are giving their all but cannot catch up!”
“Waaaaah!”
“Go! I bet my entire fortune on you!”
Crack!
“Let’s win overwhelmingly! Run!”
Crack!
Running at full power from the start allowed me to circle the track without any interference. Focusing solely on avoiding mistakes, I achieved a perfect race in a state of ecstasy and took first place.
Crack!
“Well done! You shortened the best record by over a minute!”
“Huff, huff.”
As I slowed down and stopped the carriage, the trainer jumped down immediately and embraced my sweat-soaked body in joy. Unconcerned about getting covered in sweat, she jumped around excitedly until an android approached and inserted an IV into her arm. Only then did she step back and say,
“I’ll go to the awards ceremony. Rest here.”
I nodded and followed the android’s instructions, sitting on the floor to receive a massage. Instead of the pleasure substances that had heated my brain, the injected drugs intoxicated me. As my erogenous zones were caressed, I freely enjoyed orgasms.
“Uuuu!”
“Haah, haah.”
Absorbing the essence released by the surrounding mares as they moaned in orgasm brought even greater pleasure that made my mind reel. After continuous climaxes, I lay there in a dazed, unguarded state. I felt a tickling sensation as the nanobots and drugs repaired and strengthened my damaged muscle cells.
The trainer, having finished the awards ceremony, approached with a man wearing a white coat. She pointed at me and told him,
“This is the mare for breeding. I’d like to complete the registration process.”
“Hmm. I watched the race. She’s an exceptionally outstanding mare. As a breeder, I have high expectations.”
The man who called himself a breeder spread my legs as I lay on the floor, sat between them, and inserted a speculum with his gloved hand to examine inside my pussy.
“The condition of her reproductive organs is excellent. I’ve seen various reproductive systems from the many mares that have been bred recently, but hers is the best.”
The breeder shone a small lantern inside my pussy as he spoke, then took out a long rod and carefully inserted it. The rod went deep inside and touched my cervix. Was he checking something?
“The uterus is also in perfect condition. Ovulation and menstruation are normal?”
“Yes, she’s very healthy.”
“If Miss Niel guarantees it, that’s reliable. Good. We’ll register her as a breeding mare.”
So the trainer’s name was Niel. Only now did I realize she had never told me her name.
The breeder took a small metal ring from his bag, attached it to the rod, and inserted it into my pussy as he said,
“I’m going to implant the breeding mare mark. It will hurt a little.”
When the man pressed a button on the rod, a burning pain flared in my cervix and I screamed. As I instinctively struggled, the trainer and two androids rushed over to hold my entire body down.
No, it really hurts!
“Mmmph!”
“Just endure it a little longer! It’ll be over soon!”
“Mmmngh!”
I bit down hard on the ball gag and endured the pain that felt like being branded with a hot iron. The larvae, startled by the sudden change in their host, emerged from the uterine wall and looked around.
After a while, the burning pain in my cervix was replaced by a cold sensation, and the agony subsided slightly. I relaxed my clenched jaw and gasped for breath. The trainer stood up and explained,
“I implanted the breeding mark in your uterus. Mares are valuable livestock, so their breeding is strictly controlled. To obtain permission, a breeder must inspect and certify them.”
“Mmm.”
When I focused my consciousness on my womb, I felt a circular device encircling my cervix, narrowing it as if sealing it and fixing it firmly in place.
