BAD ENDING 004: The Tamed Mare
“Ah… aah… ah…♡ Master is watching me… Riri’s gaze looking down on me… pressing right into this filthy Military Horse’s pussy…♡”
Sonia’s body shuddered. The mere touch of Riri’s eyes felt like a red-hot brand searing straight through her, pleasure lancing every nerve.
The taming had already sunk so deep into her mind that the blonde Military Horse no longer needed Riri to stroke her golden hair. At first it had taken twenty strokes, then ten, then five, then three… and finally just one. After that single caress, any chance of the taming ever fading had vanished completely from the D-class hero Sonia.
Ordinarily her pitiful mental resistance would have clawed back against the taming effect over time. Riri never gave it the chance. Over and over she applied her taming skill—simply by gently stroking that blonde hair—forcing the intensity all the way up to four hearts.
Under that overwhelming mental interference, Sonia’s scrap of resistance was crushed to dust and blown away.
Far from wearing off, the heart gauge that had been slowly filling even when left alone finally broke through its last barrier the moment Riri returned with the finishing tools—just from the sight of them.
The empty outline of a fifth heart began to shimmer faintly above Sonia’s head.
“Hearts… five of them…♥”
Riri’s eyes went round. This was a realm she had only ever heard of in legends. Perfect taming. Absolute obedience.
If Sonia were taken to a specialized clinic for hypnosis-and-brainwashing victims right now, there might still have been some hope of recovery.
Unfortunately, the only people present were the innocent trainer Riri—who had no idea that this state was essentially identical to hypnosis and brainwashing—and…
“Ririi…♡ Master…♡ Look more…♡ Watch more… with Riri’s eyes… observe this stupid filthy Military Horse’s pussy…♡”
…Sonia herself, already a lewd Military Horse who was voluntarily pouring loyalty, submission, and the desire to serve into that empty fifth heart that had appeared without even being touched.
For the two of them, the option of “treatment” simply did not exist.
Beads of sweat made her pink areolae gleam as if painted with gloss. That heat traveled straight down to her lower half, where the already-soaked, pathetic pussy of the lewd mare Military Horse Sonia looked ready to start steaming.
“So… nia. Unnie… eet… heet… fuheet…♡”
Riri could not hold back her laughter.
The once-dignified hero unnie had, in the space of a single finishing tool held up before her, transformed completely into a personal female Military Horse whose pussy was dripping wet. Riri had been briefly flustered watching that instantaneous change, that perfect process of corruption, but she quickly steeled herself and decided to thoroughly spoil the adorable masochistic mare right in front of her.
“Heh… heh…? You really are a shameful hero unnie. Showing off the most embarrassing parts of yourself as a hero, as a Military Horse… and as a woman… Even if a Military Horse is a female… it’s still filthy, isn’t it, Sonia unnie?”
Tap. Tap.
Riri playfully kicked the insides of Sonia’s spread thighs with the tip of her shoe.
The sturdy hero Sonia would not be hurt, but the meaning of the act was crystal clear.
Riri even made little “tap, tap” sounds with her mouth as she berated the lewd Military Horse.
“A mare too embarrassing to show anyone… like this… eet! A female Military Horse unnie who just sprawls out with her tits and pussy completely exposed… what should I do with her?”
“Ah… aah…♡ Yes… this… this Sonia is… Riri’s… shameful… inadequate female Military Horse…♡ The kind of hopeless masochistic Military Horse who gets even wetter just because Riri is looking at her pussy… with not a shred of shame left…♡”
“Heee… so you’re a filthy Military Horse who’ll spread her legs for anyone, is that it, Sonia unnie?”
Riri deliberately played along with Sonia’s aroused mood.
Thinking it was nothing more than playful teasing, Riri had no idea that her words were filling the empty space of that fifth heart—the proof of taming and the token of trust floating above Sonia’s head—at a terrifying speed. She was raising the mare, the Military Horse’s trust even higher. Completing perfect domination.
“Ah… no… only in front of Master Riri…♡ When Riri looks at me… I can’t hold back as a Military Horse… I just become a female…♡”
Along the insides of Sonia’s thighs, the lewd Military Horse’s juices that she could no longer hold back began to trickle out in thin, clear threads, dripping toward the floor.

Sonia’s pathetic pussy twitched weakly. It was the sensation of her deepest place, her greatest weakness, being completely dominated.
That skin flushed just from being looked at… Sonia unnie… she’s soaked… she’s really that excited…
“I-if it comes out like this, then even I get excited… and I have no choice but to show you, you know?”
Riri lifted the longest, firmest tool among the things she had brought. She slowly waved it in front of the female Military Horse’s golden eyes—those pupils shaped like hearts.
“Reallyyy…♡ Master… Ririi…♡ This filthy Military Horse Sonia is so happy… Master’s that… that… show it to this female Military Horse…♡”
What Riri held up was no ordinary toy.
It was fundamentally different from a double-ended vibrator meant for mutual pleasure.
One end had leather straps and buckles so the user could secure it firmly around her waist without slipping; the other end was a solid protrusion designed solely for aiming and thrusting into a target.
A perfectly asymmetrical structure. Focused not on the joy of being penetrated, but solely on the joy of penetrating— a common one-way attack dildo for women in this world: a wearable strap-on.
“Nn… like… this… heet…♥”
Without hesitation Riri tugged her light-purple frilled panties down a little. As if it had been waiting its turn, a black, gleaming, slightly shortened on one side lewd implement revealed itself.
In the end it was a “mountable dildo” that also delivered vibration to the wearer. Riri pushed it between her thighs and tightly fastened the leather straps around her waist so it would not shift.
The genius trainer Riri had used this tool only a handful of times. Three mares who had passed through her hands, plus two more she had been forced to “persuade” after they refused contract renewal… only five real experiences in total.
“And today makes six, Military Horse unnie. Ah… even if it’s not my first time… it’s still a little hard to move, you know…?”
Riri blushed as if embarrassed. The hard vibrator that had taken the place of her panties, its black gloss catching the light whenever she gave it the slightest shake.
That vibrator, fixed firmly against Riri’s trainer pussy and jutting out, she slowly waved in front of Sonia’s heart-shaped pupils as if flaunting it. Riri was now the perfect master of a female Military Horse.
“Ah… aah…♡ Master’s cock…♡ Master is… Master…♡ cock…♡ with Sonia’s pussy… Riri’s cock… that black… shiny… cock…♡”
A cry mixing shock and rapture burst from Sonia’s lips. Riri was not truly a futanari, yet that tool that had become part of her master’s body held even greater meaning for Sonia.
A female genius who could make her master a little wet with nothing but filthy words, without even touching her. A Military Horse sending lewd gazes at the attack-type mounted vibrator that, though not actually part of Riri’s body, swayed as one with her waist. Respect for her master, absolute submission, and the uncontrollable anticipation of a lewd female slave.
“I-if you look at it with such greedy eyes… even I… even I… get wet, Military Horse unnie…? But! Just wanting something doesn’t mean you get it… you know that, right?”
Sway… sway…
As the glossy dildo, strapped tightly to Riri’s training pussy and hanging from her waist by leather cords, slowly swung left and right, Sonia’s heart-shaped pupils, those golden eyes, followed its movement as if entranced.
“Master… ah… aah… you’re so mean…♡ This Military Horse Sonia is… nothing but a tamed female who can’t do anything in front of Riri’s cock… a hero who’s already lost… please turn this Military Horse Sonia into Riri’s pussy slave…♡”
“Hmm… what should I do…? Sonia, the floor is cold… will you lie back down on the sofa for me?”
At Riri’s command, the female Military Horse who had been on the floor with her belly exposed and thighs raised did not hesitate for even a second. When Riri gave her a light, careful kick,
the five-heart female Military Horse Sonia answered in a voice full of joy.
Sonia rose with smooth movements and headed for the sofa. She sprawled out again on the sofa, which was easier on the hips than the bare floor, returning to the exact same pose as before—thighs lifted high beside her head, both hands pressing them firmly open.
