Mare Training: Warhorse Conditioning
Sonia's mind had long since been swallowed by successive waves of climax—a kind of cerebral pleasure she had never once experienced in her entire life.
She even seized the spirit's arm as it rummaged through her mind, pulling it deeper, deeper still with insistent tugs. It was the Horse Spirit who found herself flustered by the sight.
"E-ehii! Do not move about so recklessly—it is dangerous!"
Far from fearing the horrific situation of a hand entering through a hole in her head, the mare was already dripping slick arousal between her thighs, ready to masturbate like a beast in heat. Sonia treated the ears protruding from her hair like a powerful vibrator that would deliciously devour her wet lower lips.
Rather than letting go of the spirit's touch that had entered within, she pulled it even harder—the very picture of a female in heat.
Sonia's beautiful face—the kind that planted lewd thoughts in everyone who met her—was completely consumed by the bizarre pleasure of successive climaxes, and the scene it created was obscenely vulgar.
The stimulation was so intense it scrambled her mind; Sonia flicked her tongue through empty air, licking at something invisible.
The spirit had been about to teach her the most basic posture for moving as a Military Horse. Sonia was already assuming one of the poses she would later learn—lifting her leg high up to the thigh.
"Uwaat...! That is dangerous, Sonia! A posture I have not even taught thee yet!"
Completely naked, Sonia raised her lewd yet sturdily trained legs and rubbed them together with fierce intensity.
The arousal dripping in beads from between her thighs was laid bare to the cold wind. The high-leg motion naturally pushed aside the foreskin that had softly concealed her lewd little button.
The red clitoris hidden beneath swelled hard as a bean, clearly visible.
"Heet... eh... hiik... don't... pull out... please...♡ Deeper... inside me...♡"
Lowering one leg while still dripping wet arousal, Sonia caught her breath for a moment, then hoisted the other leg high like a magnificent Military Horse.
She had only lightly infused her blessing into Sonia's body for Military Horse training—yet Sonia was reacting like a breeding mare for sexual service. The Horse Spirit could not hide her bewilderment.
The spirit carefully tried to withdraw the hand she had used to inject the blessing. Mare Sonia's hand stubbornly blocked her. Gently restraining Sonia's hand, the spirit began pulling her arm free with force.
"Ehei... just a little... wait... it is done... hup!"
Pop...!
With a cool, crisp sound like uncorking a tightly sealed jar, the spirit's arm fully withdrew from the mare ears sprouting atop Sonia's head.
"Hoo... it is finished... art thou well, Sonia?"
The spirit asked out of concern for Sonia, who until moments ago had been moaning "Heuung...♥" and pulling her arm even deeper.
The blessing the spirit had bestowed was thoroughly practical—easing the strain of standing on tiptoe or thrusting out the chest as a Military Horse. That was why she had put her hand into the ears sprouting from Sonia's head. The result, however, was nothing like she had expected.
"...I'm fine? I was just sitting a moment ago... ah... a... aah...? Uhiit?! ...Higiiiiiiit...♥"
The instant the spirit's touch left her mind with that pop, the final dam of reason holding back Sonia's lewd body burst completely. Arousal poured down her thighs in a waterfall.
"...Ehet... het...♡ It itches... it itches so much...♡ My pussy... it itches so badly...♡"
"So... Sonia...? Why art thou acting thus...! Compose thyself...!"
Right before the spirit's eyes, Sonia began casually rubbing her most intimate place—something she was only supposed to touch as a "reward" for training—as if it merely itched. She was the very image of a mare fully in heat.
"Th-this has never happened before... so why only with Sonia... h-hark, could it be that the mares of this world—nay, the people—have different constitutions?"
The spirit's mind was in complete disarray. Driven by irresistible curiosity, she had thoroughly read everything from Sonia's mind to her stats and personal perks—never considering the enormous strain this placed on Sonia's psyche—and simply assumed the reaction stemmed from cultural and physical differences.
(Ha... but an "ability to keep one's tongue from shriveling when eating potato chips"... is it not only natural to be curious...?)
"Ehet...♡"
Still recovering from the horrific aftereffects of having her soul read down to its deepest depths, Sonia collapsed to the ground, dripping mare-heat juices.
She seemed to right herself for a moment, only to flop onto the grass and start rolling about. The ground she tumbled on was not a cozy living room floor or a bed, but the dirt of the Military Horse training grounds—yet her sturdy D-class hero body showed no sign of injury.
"Pushiii... it... het...♡"
Like a balloon that had lost all its air and will at once, Sonia's body went limp and pressed fully against the cold dirt.
Her breasts, which until moments ago had been thrusting up stiff with pleasure at the spirit's strange intrusion, and her lewd nipples, erect hard as stone, were now crushed against the rough ground under Sonia's own heavy weight.
Lying face-down, the gritty texture of dirt and small pebbles scraped and stimulated her hypersensitive nipples; even that faint, unpleasant stimulation made Sonia's pathetic mare-pussy twitch and freely drip clear arousal, soaking the ground.
Uncontrollable drool trailed from the corner of her mouth in transparent threads, and the sight of her sprawled on the ground using her massive breasts as mere cushions was that of a completely disabled female who had lost all reason and dignity.
"U... mm... all of this is a necessary process—I trust thou wilt understand!"
Had it merely been the experience of having her mind stirred into chaos, Sonia might have endured it. What she had just undergone was not suffering of that order.
The Horse Spirit had gone through Sonia's stats and perk list line by line, page by page—like a librarian dusting off an old bookshelf and turning each leaf—combing through every piece of information that constituted Sonia's existence.

It was the sensation of having her soul stripped bare. An indescribable mental invasion in which even her deepest secrets and desires—things she had never shown anyone—were thoroughly violated and analyzed. That she now lay sprawled on the dirt like a masochist addicted to climax was, perhaps, an inevitable result.
Hguuk... kkeut... hiit... het...♡
Even amid the residual sensation of her soul being read and the aftermath of unending successive climaxes, Sonia resisted desperately. Drooling freely, she bit her lower lip until it nearly bled, struggling to suppress the rebellion of her lewd body as it tried to be swept away by yet another wave of pleasure.
To somehow follow the spirit's utterly unhelpful instruction—"Endure it!"—she controlled her trembling body.
Her fingers had been drifting unconsciously toward her strangely itching secret place; Sonia wrung out the last of her willpower and barely managed to pull them away.
Uuu... huuk...
"The blessing has been safely... ahem... this body has put more effort into reading thee than expected! I am sorry... yet a blessing is a blessing... in any case, I am sorry..."
The spirit coughed awkwardly, as if acknowledging the mistake her excessive curiosity had caused. This place was a subspace that existed solely for Military Horse training.
The vast field was fully equipped with a training ground, a washing station, a discipline room, and even the stable where Sonia would now stay. Beyond that, nothing but blue grassland stretched to the edge of sight.
Twitch... twitch...
Sonia could do nothing but leak fluids from her upper and lower holes in the aftermath of successive climaxes. The Horse Spirit examined her firm, healthy thighs with the interested eye of an appraiser.
Poke. Poke.
The spirit poked her thigh with her cute little fingers, but Sonia's body, still captive to the deep afterglow of climax, could offer no resistance.
Instead, Sonia's firm calf and lower-leg muscles responded instantly to the spirit's touch.
The spirit would not know it, but that sensation was remarkably similar to something Sonia had experienced before.
Just as the soft latex bodysuit issued by the Megacorp Association had momentarily hardened like steel under Luce's powerful impact, each poke of the spirit's fingers made Sonia's leg muscles gather strength and harden like stone.
"Ahem...! Excellent! Truly magnificent... this is the real deal!"
These were Sonia's legs, powered up by the spirit's blessing. Beyond merely standing on tiptoe all day without pain, her kicks now carried a dangerous, destructive power incomparable to before.
The D-class hero who had once crushed empty cola cans with just two fingers had, through this fateful encounter, finally obtained the powerful close-combat ability she had so longed for.
