Chapter Text
Silence marks the path to damnation.
It was a cool night under a full moon when Grass Wonder made the fateful decision to reach out in faith. An umamusume nun who resided at a school with several other sisters, she had spent much of her life in a world of her own, following the sacred virtues, and enlightening others to follow the true path. It was a journey with hard work, that demanded full devotion of her body and will, but Grass was a holy sword, honed to perfection, able to pierce even the vilelest sin, and free the most wicked sinners.
Or, so she thought.
For on that very day, that path had instead led her to ruin…
Betrayal.
The word repeated in her head, reverberating in a world that had suddenly grown more hollow, more silent…
Blue eyes stared up at the moon on the trail she walked, basking in its glow, knowing that somewhere else, so to did her beloved-
With that wretched orange vixen.
Anger and Envy twisted in her heart, ruining the little bit of piety she sought to save.
“No matter what, I’d still forgive you if you came back.” Grass's words broke into the uncaring, unresponsive wind.
I’d still love you, always.
No matter if she sinned or hated her, Grass Wonder would always love the source of her pain. Another umamusume nun who spent their days together, dark brown hair messy and cute, white bangs as bright as the stars above.
But now she is gone.
A cold wind brings Grass back to reality, and the mission at hand, stirring her forward in the wake of change. She walked down the trail, alone, haunted by memories and dreams that sank into her mind, of a body she would never see or hold again. Feet moved at a soldier’s march, fists clenched into tight balls, trying to strain the sinful thoughts from her body.
Several minutes later, she reached her destination, quiet and alone, a cathedral some distance away from the school, only open during certain days while the sun was out.
Venturing into her lord’s holy place in this manner was nothing short of sacrilige-
But so too, is holding on to these thoughts.
She approached the dark gothic building, black cobblestone shining grey in the moonlight, staring up at the tower above it that pierced the very sky.
“Goddess, forgive me.”
A powerful leg blasted through the giant wooden doors, sound echoing into the hollow temple within, beckoning the sinner to her fate.
Grass walked forward, heart full of hope in her Goddesses, feeling their strength pouring into her skin this particular night. She looked around as she stepped inside, black heels clacking on empty stone floors, pews empty and stainless, every book placed neatly and perfectly where it belonged.
Just as we ensured.
The room lay dark and unlit, save for the altar at the end of the room, illuminated by the massive circular stained glass window above her, a depiction of the three goddesses touching fingers to the Earth.
Thy will be done.
Black soles moved forward unshaken, knowing every inch of this temple by memory, every last nook and cranny embroidered in her brain.
Clack.
Clack.
Clack
Clack.
She folded her hands as she stepped into the light, and silently prayed that either her wishes would be granted, or her pain would be erased. Silver judgement danced upon her skin, anointing her with the audience of those she sought. A light, invisible flame danced upon her form, a candle seeking to banish the night drowning her mind.
Blue eyes hushed close, and as they did, so too did the door behind her.
A quick glance back revealed nothing there, nor could she sense anything.
Whatever, it’s an old door that tends to do that, after all. And, it means my communion won’t be interrupted.
She smiled, and took a deep breath, before finally confessing her sins.
Grass Wonder prayed to the goddesses, seeking for them to heal the wound in her heart, to punish the one who took away her beloved sister, anything that would allow her to have the happy life she took for granted. She sought strength, she sought wisdom, and she sought change.
But throughout it all, she never once sought forgiveness.
Not for the envy towards her sister, who was fated to stay with her.
Nor for the anger which burrowed in her heart, towards the harlot that stole her away.
But most bitterly of all, she stayed her tongue and sat in silence, when images of the body she coveted danced in her head.
To be dishonest is a sin… And I will not apologize for loving her.
And even within her own head, she lost. A dull ache shifted in her chest, as at the corners of her imagination lay a thousand fantasies of the flesh.
“I pray that our dear sister will return to her home with us, and find happiness here…” With a final statement, Grass concluded her prayer, and stood in the light, praying hopelessly for some form of answer.
She stood for minutes on end, burning in the silver light, the moon igniting her in its radiant gaze.
And then.
She felt IT.
Somewhere, just beyond the circle of prayer, another warm body waited, silent and judging.
An angel? Special Week? That wretched whore?
Grass’s breath stayed in her throat for minutes on end, fearing that if she tried to see for herself, her prayers would go unanswered.
So instead, IT spoke for itself.
“Salve, soror dulcis [] Hello, Sweet sister…”
A light, playful tone beckoned an eye open, finally giving in to whatever stranger tempted her attention.
“What is it-”
Grass’s eyes grew wide in shock, tail and ears flaring up as she jerked back in complete surprise.
IT stood in a full nun outfit, tall and dark, another Umamusume, she could tell, but something was off. The air around this stranger was dark, fiery, bristling with an energy Grass never saw from another sister before, not even another Umamusume. Brilliant, blue eyes stared back from a form in the darkness, struggling to make out the rest of the girl’s form. Behind the stranger, she felt its tail shifting in the dark, unable to see its full appearance.
“Care to invite me into your circle of prayer? I’m afraid we might both benefit from the company tonight.” A single white tooth glinted in the dark, unnaturally shiny and clean.
Grass sighed, and gave a polite bow.
“Well, the cathedral is closed during these hours, but seeing as to how I’m already breaking curfew, I suppose you can join me for tonight.”
“Thank you, amor.”
And with that, Grass’s fate was sealed.
The girl stepped into the moonlight and strode atop Grass, and she immediately regretted her answer.
No no no.
The stranger was no mere Umamusume, that was immediately clear. A thin wiry tail wrapped behind its legs, a black cord that was significantly longer than any other person’s tail she had ever seen, and far thinner, while also lacking any strands of hair. Her eyes glanced up to an, admittedly handsome, tan face, commandeered by blazing blue eyes that were even more stunning up close, and brilliant white teeth, with a notably sharpened fang.
Grass stumbled backwards, frozen in fear at whatever had come to answer her calls tonight.
“Now now, is that any way to treat a fellow sister?”
This was not a face Grass recognized, nor was it even a mere human or Uma, no, this was something else altogether.
“Who… What are you?” Grass stammered, in complete shock as her faith proved its reality in the worst way possible.
“Why me? Oh dear sweet one? Oh, well feel free to feast your eyes, your heart, body, and even soul upon the presence before you-” She swung back around, spinning her arms around in a fiery vortex of air. “For I am, a succubus!”
Demon.
“A… a suck-you-bus?”
“No no no-” The succubi leaned in, whispering it onto Grass’s face with ashy, smoldering breath “Suh. Cue. Byss.”
“Succubus?”
The devil stepped back, awaiting her own title as she swung an arm to her ear.
“Again!”
“Succubus.”
“Louder!”
“Succubus!” Grass raised her voice a bit, a smile creasing at the edge of her lips.
“One more time!”
“Succubus!”
“There we go, mirabile!” The stranger clapped her hands together, delighted by her own little performance and number one member of her audience.
Something in the air shifted, and Grass felt as though the devil before her was pulling in everything around her, a vacuum that ate at the quiet she had taken refuge in. The succubi began to saunter slowly around her, a shark circling in waters Grass was not ready to swim in.
But still, Grass did not budge, holding tight to her faith and strength, that she would overcome this.
Low, beckoning words guided her back to the monster circling her, outside of her vision.
“And…. do you know what succubi do???”
Grass’s thoughts died in her throat, burying the knowledge she should have never known.
“Nope!” She smiled, a sweet angel certain of her place in heaven.
Liar.
“I feast on your sins, sinner.” A giggle played upon her back, shrill and high, as though the devil had been waiting to say it the entire time.
“Well, I hate to say it, but you’re gonna starve tonight.” Grass closed her eyes, burying guilt under an avalanche of virtues. She thought about her years of service, of guiding others to enlightenment, for never once doing such foul things as-
“Hehehe, oh dear, you do know, lying is also a sin? Grass Wonder…” A voice cackled behind her, and she turned her head to see the succubi, relaxing in one of the pews, seemingly quite at home in the one place built to be a refuge from her kind.
“What are you getting at?”
The succubus smiled at the response, finally detecting genuine agitation from tonight's target.
“I am saying that, I think we both have something to gain here tonight.”
“Hmmmph-” Grass puffed out a jet of air in disagreement “As if I would ever negotiate with a demon.”
“Succubus! And-” She stood back up, walking back into the light “-You already did, when you invited me to join you tonight! Honestly, you should be overjoyed, you at least brought one prayer to life tonight! And if you have me, perhaps I can answer one of yours…”
The final words rattled in the air, burning on Grass’s tongue.
“Again, succubus, I would neve-”
“Do you know what a succubus is?”
Grass stared into blazing blue judgement, and shuttered her eyes, drowning her own memories.
“N-”
“Another lie, again. My my, dear sister, you may never see the light at this rate.”
A cheeky grin entered Grass’s face, fully delusional in her retorts by this point.
“Yeah, well I am standing in it, so I’d say I’m already there!”
Footsteps thumped towards Grass, and she looked at the dark figure entering her circle again before her, its 'horns' standing tall and proud over her.
“Ah, how delightful! For that too, is what called me here tonight!”
Grass froze, shock burning into her face, red paint staining her cheeks with the mark of a target.
You don’t mean…
“Anyways, as I was saying, oh my feisty little sinner! Is that we succubi, indulge in the pleasures of sinners, so that we may not hunger and starve, and so that you too, may enjoy our time together! It is a win win relationship, an exchange of desires, so both parties may prosper!”
Grass winced as deep and twisted desires floated to the surface, forcing herself to look away from the succubus. A single fang glinted in the corner of her eye, and she knew she had lost.
“I would never stoop so low as to break my vows for a demo-”
“Succubus!”
“RAAAAGH!” Grass reached out an arm to try and catch the pest, and was stunned to see how agile her target was, evading her strikes with ease.
Of course, she’s an Umamusume dev- I mean succubus.
The annoyance fluttered about in the dark, making Grass dizzy and confused.
“You know what else? Something far less people realize, is that we can taste desire. Lust, Envy, Gluttony, you name it, we taste it! And my cherub-”
Footsteps clattered in the dark, lurking within the back of the church.
“I can taste it, all over you!” The voice resonated and bounced in the chamber, a dark reading that ate at her very soul.
“Anger and wrath, blazing so true to your core! I can feel it, those punches you threw at me, you really did want me dead there! How marvelous, for one of the holy warriors, I feel so honored to be in your presence. Genuinely.
But then, there’s two others, I can feel how they have made excellent kindling for that wrath into what you are tonight, an overstretched soul set to pop!
One, is lust, oh so deep and buried, long kept away from all your sisters, and even from your preachers. Even tonight-”
The sensation of the door closing behind her replayed in Grass’s head, and dread rolled through her, realizing she had been doomed the entire time.
“You refused to ever admit your own sin! Even when it was your own lust and desire for the flesh, that brought you to covet.
And that brings us to tonight, Envy…”
Sour notes caught in Grass’s throat, anger and resistance striking blows with truth and desire.
“You loved your sister dearly, thought you too would be together, even beyond death do you never part. Yet, you never saw how unhappy she was here, and could never offer her enough to keep her around. So, when the wonderful - I mean, she is genuinely kinder than any of the word’s you’ve thought of tonight- Umamusume came to whisk her away to her own happy end, that left you behind, bitter and alone.”
“Stop. Talking.” Grass’s breath was low, a warning that she knew carried no actionable threat behind it, but desired so badly to silence that voice for good.
That voice in you-
Grass’s mind, no, soul betrayed her anger, recognizing that every word, every accusation, was true.
A softer voice suddenly appeared to grace her, before a warm hand brushed her face, appearing from the shadows.
“I too, live quite a lonely life. Always have, always will. I’ve never known love, but I’d like to…”
Grass gave in and looked back, caught in blue whirlpools full of genuine tears.
“But, if my purpose, can make you feel a little better, I’d love to do that, at least. After all, that fire in your soul is so beautiful, it makes the lonely dark melt away...” Puppy dog eyes stared into Grass’s soul, disarming her anger, fists unclenching as she breathed in the blazing vapors enveloping them.
“I… I am sorry! I’d like to be of help! And honestly, it would be nice if I could let that fire loose, and be what you recognize, just for one night… but I took an oath, succubus… No matter how much, I want… it.
No matter how much I desire… desire…
I cannot accept your request, even if I’d love to.” The truth came out harder than anything else, but once it did, she felt lighter, more free, a confession borne to an otherworldly creature, a confession that would never follow her beyond tonight. Her ears fluttered as she took in the breath circling around her, tail wagging as their shared warmth ate away at her own loneliness.
If only…
“Ah sweetheart…” the succubi cooed in a warm tone behind the nun “why do you resist?”
Sharp nails raked over Grass's black dress, heavy muscles snaking down to where an accelerating heartbeat betrayed her piety.
“I can feel it, taste it on the tip of my tongue, that smoldering inferno that begs for release.”
The succubus pulled her in against her body, a dark, devious tone snaking through her vocal chords.
“Me facis flere… Please, stop fighting your own soul…”
Something black and wiry rolled upon Grass’s back, making her shiver, trailing up with tantalizing danger.
Perhaps an antidote is required…
Wide blue eyes watched as a dark, thin wire gleamed against the moonlight, a smooth, heart shaped tip flicking with anticipation. The succubi’s moonlit tail launched forward, coiling around Grass’s throat, sending a shiver into alert ears and down her spine. It flicked, once, twice, below her chin, each taunt accompanied by a giggle from behind.
“Read to admit defeat?”
“Try as you may… demon… I… will not-” Good… “-falte-AAA-”
The serpent around Grass’s throat clenched, choking her final prayers in a rasping breath, before yanking the girl back into widespread fingers waiting with a dense, reassuring grip.
“Hold still... love.”
Sssschink
“aaaaugh!?!?!”
A sharp, stabbing pain suddenly entered the back of Grass's neck as the succubi's sharpened tail stabbed her from behind. A broken whine left the nuns throat, legs and body twitching as shock rolled through her body. Grass’s own tail coiled around her legs like a dying snake, electricity and venom frying every connection with her own body.
With a final, satisfied hum, the Succubi released with a wet slap that emanated through the empty pews. The sharp pain left Grass’s neck, leaving behind a wet, sticky residue from a throbbing wound. Pale hands reached back to investigate, and upon returning, greeted blue eyes with a pink, shiny sap.
“There, that should do it.”
Grass reached up and ripped the cord from her neck, falling limp as the firm claws that held her upright released her to spasm on the floor. The world shook, every inch of it vibrating and scorching. Liquid fire flowed through her veins, a chain reaction from her neck to the rest of her body setting every inch ablaze.
With struggling arms, the chestnut forced herself up, turning and collapsing into awaiting arms.
Hot. Heavy. Molten iron surged through every vein.
“Such passionate devotion fighting its demise, a dance of two flames! One seeking libertate, the other seeking caelum, it makes my heart soar!”
Blue eyes stared into even brighter blue eyes, the world swirling around 2 pools that burned into Grass’s mind, seeming to devour every inch of darkness in the cathedral.
O Satanas… I might’ve used too much.
Visions of buried fantasies and dreams of the skin poured through Grass’s mind, buried sins ripped forth by the demon that taunted her above. Her throat was sore, her breath was hot, and her body rippled as waves and waves of desire knocked over her crumbling walls of celibacy. Pale hands balled into fists, and Grass breathed.
Slow.
Heavy.
Each breath felt like she was swallowing the entire atmosphere.
The succubus watched with confusion as the shaking and vibration settled to a minimal level, only noticeable in the arms she held directly, watching as her prey stirred and suddenly, seemed to regain control?
Oh? Yet the fire remains, I can taste it, I swear…
Breath by breath, Grass swallowed the lava pouring through her body, no longer fighting it. No, she couldn’t. With a hidden smile, she accepted the succubi's condemnation, and she realized she could not fight her own honest self.
So instead, she looked up, and truly absorbed the sight before her.
Smooth, tanned skin sat in black habit not unlike her own, surprisingly the warmest tone within the cathedral. Horns… no, ears sat above, hooded within the coif, flickering with anticipation, as deep, swimming blue eyes swirled and burned into her soul.
A bead of sweat rolled off Grass’s forehead as she realized with startling clarity that she was already damned from the start… nay, long before, and now this creature manifested as a result of that desire that had eaten her rotten. Piety burned in the wake of honesty, swallowed into an abyss as she accepted her reality.
The succubi listened to the rhythm of the pulse she held in her fingers, noting the very moment the beat changed, mellowing into a heavier, slower pace.
Ah, it is time, pro festo…
A fanged smile greeted Grass’s agitated glare, both abundantly aware that the other already knew.
“So, are you ready to accept your fate?”
The chestnut girl released a sigh as her body vibrated once more, sending a twitch from her ears down her spin to her tail, as the last vestiges of her dignity died. Blazing blue eyes burned into the succubi’s heart, practically drooling with excitement.
“I… will make you regret this…”
Such defiance. Such boldness. I think I- I’m in lo-
The succubi paused for a moment, ears flicking and eyes going wide, as tonight’s prey brought with it a new discovery. The confused expression lasted only a second, quickly transforming into a monstrous grin as she leaned in close, each word taunting the fallen sister.
“Oh, I do hope you try!”
The succubi removed an arm to the top of Grass’s head, landing right between her ears and holding steady, holding the other arm still tight in her grasp.
Want.
Need.
Touch.
Desire.
Burning.
Grass’s limbs still weighed heavy with the presence of the catalyst in her blood, still truly unable to put up a proper fight as the monster drifted over her. A wet, hungry tongue reached for her chin, before dragging upwards, tasting the delicious skin of a newborn sinner before rising back up to judge the flavor.
Angry, Envious, and so deeply, deliciously lustful beneath this garb… Ah, my beautiful angel, fallen to Earth.
The hand on the back of Grass’s skull gently slid down, fingers playing with silky fibers, before a thumb rubbed against her ear, drawing out a choked moan. The succubi purred in return, enjoying every reaction, every proof of her existence reflected through Grass.
Slowly, she leaned back in, pulling Grass back in return, melting into her mouth with starving lips.
Gently gently, let’s try to savor this…
The succubi tried to calm herself down, hoping that she could make this meal last a bit longer, satisfied to merely press against the sinner’s lips as she stole her first kiss.
Electricity poured into Grass’s mouth, eyes going wide as she stared into the succubus before her, eyes closed, a dense fog rolling against Grass’s face. A curious tongue flicked to taste the air, catching the overwhelmingly sweet bitterness of dark cocoa, popping with flavorful spices and peppers. It was…
Good?
Grass stood a little more upright, emboldened by her rising curiosity, pressing deeper and firmer back into the invading mouth.
More.
A tongue leapt out of the shorter girl’s mouth, pressing past awaiting lips and into the opponent’s own mouth. Opposing taste buds grinded against one another, each time exchanging flavors and heat, until both their mouths became a shared broth. A wandering hand dragged Grass even further, pulling onto the succubi’s hip, and smiling as she felt it roll into the touch with a deep moan.
Yes baby, just like that. Hunt me. Want me.
Grass's hand reached further, feeling the soft flesh of sculpted ass cheeks just beyond that, digging her fingers into the thin layer of fabric that cloaked the devil in any sense of dignity.
More.
Another hand left its position on Grass’s wrists to go on its own adventure, tracing the chestnut’s sculpture before flicking at the edge of Grass’s tunic. Grass’s tongue grew more bold, pressing deeper into the mouth, pressing the monster back, grinding against the other’s fang with all the curiosity of a cartographer defining its shape. Warm fingers dug back into her outfit, burning hot and red against her skin. The succubus grew equally excited, adding one finger, than another, no longer satisfied to tease, but actively exploring Grass’s body, before finally lifting up the fabric partway to allow her arm to roam.
Cold air poured against Grass’s skin, but all it did was make her hungry for that warmth before her even more.
The hand raised higher and higher, indulging in every shiver formed in its wake, mapping out the body into her memory.
I will remember you, dear ‘sister’, for a loooong time.
“Sssssszzzzzzhhhh-”
The succubi's hands reached a hidden mound of flesh, delighting in the way Grass’s whole body seemed to recoil at the mounting tension.
More.
Grass grew hungry and impatient, the venom seeping deep into her body and mixing with the latent desire, unleashing a beast set to ruin any demon.
“Ahhhyiiiieeeee?!?!”
The succubus yelped as a strong, tense hand pulled her buttock in, fingers digging in deeply, ravenously. The succubi's roaming hand folded in further at the sudden jolt, cupping an entire breast suddenly, drawing a deep groan out of the beast that stole her breath.
Blue flames opened up to the succubus with a half lidded, predatory gaze, paralyzing the succubus set to eat her.
O Deus.
Panic and warning alarms she didn’t even realize she had blared in the succubi’s brain, but greed won over first, choosing instead to dive even further, launching her hand instead into Grass’s skirt.
Wandering fingers met thin fibers, light and wispy, just above a fold of skin where heaven awai-
Oil mixed into fire. Venom blurred fantasy into reality. And the succubus got her reward.
In the blink of an eye, the succubi’s exploring hands were punished and slammed against the altar behind her, eyes going wide as she stared into stormy blue eyes that billowed with rage and lust. Chestnut ears stood pointed and crooked, flared wide, a set of demonic horns resting upon the prey rising above her. Those same eyes shut tight in a tense return of her willpower infused with desire, as the succubus victim's smile grew wide with a calm, self-assured strength.
“Oh sweetheart don’t be afraid… I’ll give you something to remember me by in hell.”
