Mare Training: Warhorse Drill
Having already bared her entire body in front of Luce once before, the second time came far more easily. The curve of her slender waist and the round swell of her hips stood fully revealed beneath the light.
The spirit looked Sonia over as if appraising livestock, then gave a small, satisfied nod. With something like telekinesis, she lifted Sonia's discarded clothes into the air and tossed them into the washing machine.
Having stripped away the shells that symbolized Human Sonia's identity, the spirit explained the next training pose.
"…This is the fundamental stance of a Military Horse. Packhorses and slave mares bred solely for pleasure all hold the same posture! Your head! And those massive breasts better suited to a female packhorse than a warhorse! Face straight ahead — all of you!"
A… a female packhorse…♡
Female… packhorse… To the spirit, it was nothing more than a functional pairing of words. But those words drove a sharp spike straight into the deepest part of Sonia. A dark, damp fantasy flashed through her mind like lightning.
A cold leather restraint suit cinched tight around her whole body. A blindfold that left her eyes seeing nothing. A bit forced between her teeth so she couldn't even moan properly.
"Mmph… mmph…! Mmph…?! Hrngh… hh…♥"
Nothing escaped but ragged breathing and pleasure-choked screams. The unpleasant sensation of bare soles against cold asphalt with every step, and the mixed stares of contempt and curiosity from people around her — she could almost feel them on her skin.
The sensation of someone yanking the choker around her neck. Helplessly pulled by irresistible force, she saw herself roaming the city's night streets on all fours in a humiliating crawl.
"…But enough fretting, Sonia! Trust this body of mine — I have turned even hopeless mares into proud Military Horses!"
Twitch, twitch… Sonia trembled at the strange words, and the spirit freely misread it as intimidation. The words of encouragement only made her re-echo phrases like mare… hopeless…, fanning her arousal higher still.
Only moments ago she had boldly thrown off her clothes declaring she would become a warhorse. Now she was dripping slick arousal down between her thighs like a mare in heat.
Had she sworn the Military Horse's oath, she would have had to hold this pose for life — but the condition that it was only for the training period brought her some relief, even as the phrase farewell to Human Sonia pulled the trigger.
Sonia was letting go of reason and shame, becoming nothing more than a vulgar, heavy-breasted mare.
(Sonia is better suited to a lewd packhorse than a Military Horse… but of course affection is needed to serve one's master loyally as a warhorse… I'll take that into account for training…!)
"Don't tense up — like this… this is the pose, Sonia!"
The Horse Spirit, complete with donkey ears and a brown tail, demonstrated in her adorable little form.
E-cup hero Sonia mirrored her exactly.
Toes pointed, chest thrust forward — a Military Horse stance whose meaning she couldn't quite grasp. She hadn't even placed a palm over her breasts, yet the mere thought that she was drawing one step closer to being a female horse made the nipples at the tips of her breasts harden like stone.
Those thick nipples stood rigidly upright, like signal beacons announcing exactly what treatment she was about to receive.
Just like those flushed, stiffly erect nipples, Sonia rose onto her tiptoes as the spirit instructed and completed the proud, chest-forward stance.
Not Human Sonia, and not yet Military Horse Sonia either — training as Female Sonia had finally begun.
"Very well. We shall begin proper Military Horse training in earnest. I trust you will follow well, Sonia!"
"I… I'll do my… haah… best…"
Trembling like a newborn foal, Sonia still unconsciously rubbed her thighs together. The friction had already left the insides of her thighs coated in a glossy sheen of wetness.
(A… a female… horse… That's right… Sonia is… doing this for training… because of the special stat bonuses… so it's fine… Not Human Sonia… Female Horse Sonia…♡ A obedient female horse Sonia, waiting to become a proud Military Horse…♡)
Sky City's nights were safe on the surface, but behind that surface there always existed a dark void.
Despite the cutting-edge surveillance of CCTV cameras mounted on utility poles and the patrol networks of heroes, disappearances that vanished into the shadows never ceased.
A student walking home late from the academy. An adventurer whose contact went dead deep in a dungeon. Or even a D-class hero with a few loose screws, like Sonia. Night's curtain cast the possibility of danger equally over everyone, regardless of status or ability.
What broke that late-night stillness was a small, childish voice. The Horse Spirit floated gently above Sonia's shoulder and asked, in the pure, innocent tone of a child deciding where to go on a picnic, where the nearest field or forest might be around here.
Calling it a field is a bit of a stretch… but the civic park is right out front. You can see it the moment you open the front door. The forest is… a bit farther, though you could call it close if you wanted…
With the bright-red ball gag sealing her mouth, Sonia transmitted the thoughts in her mind directly to the spirit, just as she had been taught.
Sending thoughts by concentrating instead of speaking still felt unfamiliar and awkward. At the same time, a strange sense of liberation washed over her at having gained another means of conveying her will.
The absurdity of the situation itself gently stimulated the masochistic streak buried deep inside Sonia.
"Ahem. Good. Picture that scenery clearly in your mind, Sonia. Then simply think of delivering that thought to me as it is! Do not let your guard down, Sonia! Training has already begun!"
Y… yes, ma'am!
At the spirit's sharp voice, Sonia straightened her back in a conditioned reflex. Beyond the black leather blindfold, in pitch darkness, she recalled the familiar path from her home to the Sky City Block 32 Civic Park.
The artificial lawn that spread out the moment you left the apartment complex. The small playground for children. The walking path lit only by faint lamps once night fell — the scenery reconstructed itself vividly in her mind.
Soon the spirit's voice rang directly in her head: Hmm… then show me this place called a forest as well! Sonia hesitated for a moment.
But an order was an order. Once more, Sonia thrust her full breasts — wrapped in the restraint training suit — proudly forward and lifted her heels slightly, settling into the pose that was already growing familiar.
Every time she took the stance, her nipples stiffened and pushed against the thin fabric of the training suit, a sensation that ran down her spine.
"Hmm. A world where Military Horses vanished because of those steel automobiles — how truly curious! The distance is a bit much, but the forest would be better. A place where the vitality of plants and trees is stronger is more suitable for training. Let us move at once, Sonia. The door… ah, one opens it with that button there!"
Hup…?!
Sonia's heart plummeted.
W… we're going? Right now? To the forest looking like this?
She had never expected this development. At worst, she had assumed a few poses practiced indoors, or — if luck ran out — simple drills in the park right outside.
The Horse Spirit had abruptly declared they would go not to Sky City Civic Park, but to the mountain that filled with weekend hikers.
It was about three subway stops from Sonia's apartment — too far to walk comfortably, too awkward for a taxi.
For ordinary Sonia, the distance would have been no problem at all. As a hero, her physical ability ranked high even among D-class. Of course, Sonia's current condition was a very long way from ordinary.
L… looking like this… Spirit?
"Of course, Sonia! Training to become a Military Horse — no, training as a mare — has already begun! I fully understand the shame! But for as long as you are being trained, you must advance with pride, conscious of yourself as a single mare!"
I… I can't…! If I wander the night streets looking like this… I'll get caught…!
The glossy black mare restraint training suit. Its high-leg cut left the bare flesh of her inner thighs fully exposed — lewd in its own right.
Wrists folded behind her back and bound tight with a thick leather waist belt, a perfect emblem of helplessness.
From the black leather blindfold that completely blocked her vision to the bright-red ball gag that enforced silence and made drool spill down her chin — no one who saw this would take it for a normal citizen's attire.
Of course, the beings roaming Sky City in the dead of night were not only ordinary citizens.
There were those kidnapped by villain organizations, brainwashed into low-ranking combatants. There were other heroes on night patrol duty.
And while almost no one would look at Sonia's E-cup bust, glossy black restraint suit, blindfold, and bare feet and instantly recognize D-class hero Sonia…
Since other people couldn't see the Horse Spirit floating beside her, at best she would look like a deranged pervert enjoying a self-training session in the middle of the night, a tiny personal drone on a chain with the other end clipped to her own collar. The more she thought about it, the more her head ached.
