Chosen by the Demon King
There exists an eroge called Magical Girl Hermes.
An evil organization called Gehenna invades Earth. Magical girls stand against them. Among those girls is Hermes, who gets captured by the wicked organization and broken through training. That is the game.
A dime-a-dozen eroge. The kind you find everywhere.
Not a masterpiece that will move you to tears—but more than enough to make you leak. A sturdy bowl of comfort food, basically.
Hermes is the title character, the main heroine, and the training target. A righteous magical girl who fights Gehenna, only to be betrayed by one of her own and dragged into their clutches.
Hermes is a woman of iron will, but she cannot endure Gehenna's training. She falls, becomes a succubus monster, and betrays the magical girls in turn.
And that is me.
Fuck.
A land that exists in a dimension apart from Earth: the Demon Realm.
There, at the vanguard of the invasion of Earth, stands the evil organization Gehenna.
And in Gehenna's freezing underground dungeon, a beautiful magical girl is locked away.
"What do I do… How did it come to this…"
Her body shuddered in the cold. Each tremor set the iron chain running from her neck to the wall rattling with her, hammering the wretched reality home.
A cell of maybe four pyeong. All it held was a small bed, a washbasin, and a makeshift toilet.
"Fuck… This… this kind of thing isn't supposed to happen…"
She lifted her head to the mirror and saw a beautiful woman sitting there.
Even seated on the floor, her hips spilled out to either side in generous flesh. Pink hair that would tickle any man's something. Golden eyes as brilliant as the metal itself, and breasts large enough to feed a hundred infants. Skin white as snow without a single blemish. A woman so beautiful that a hundred out of a hundred would turn to stare if she walked down the street.
If only it weren't me.
"I—I was careful… I avoided every chance of being betrayed… So why… why is this happening…"
She had been playing Magical Girl Hermes when, at some point, she came to her senses as Hermes herself—the game's main heroine.
Gender-bent out of nowhere. Made a magical girl out of nowhere. Fighting Gehenna out of nowhere, until she became the strongest of them all, just like the original Hermes.
She would have quit if she could. But in the game, a Hermes who abandoned being a magical girl got kidnapped and trained as retaliation—so quitting was not an option either.
"I reincarnated as Hermes and lived so carefully for more than a decade… And now, of all times, I get betrayed…"
She had never actually played the game through. She had only flipped through the CG collection that got her off. She knew the rough outline of the story, but not who betrayed her, why Hermes was taken by Gehenna, or what kind of training she received.
Anyone could have sold her out to Gehenna, so she had built a wall between herself and her fellow magical girls. She had not exchanged a single word with them.
It had been the same right before the kidnapping. She had been fighting Gehenna's monsters when she saw Galea flee into a building. She had followed inside with another magical girl… and from that point on, her memory was blank.
"My magic wand is gone too… Where did it go… Without it I can't use magic…"
The wand was an essential tool for a magical girl to cast spells. Without it, she was nothing more than an ordinary person in a magical girl dress.
She was digging hard through memories fogged like mist when a rusty hinge creaked and the door swung open.
"Long time no see, Hermes. Looking good."
"Galea… is that you?"
The one who had come for her—no, the monster—was Galea, Gehenna's infamous female executive.
A chimera of wolf and monster, Galea was sadistic by nature. She especially loved tormenting her victims by spanking them, striking their breasts, or kicking them between the legs.
Videos of Galea abusing magical girls circulated in the underbelly of the net.
And now that vicious Galea stood right in front of her.
"I'm honored. The great Magical Girl Hermes remembers my name."
She looked down at Hermes in chains and smiled with satisfaction.
"Hard not to. You're the small-fry monster I've crushed more times than I can count. How's the wound from last time?"
"All healed, of course. You little shit. Finally got you. The second you got dragged into Gehenna, your life was over ♡"
Galea leaned in, glaring down at her.
Through the highly revealing leather outfit, a taut, well-balanced muscular body was visible. Healthy beauty radiated from her smooth brown skin—and, as if to prove she was still female, her breasts swelled full and firm. Her dull silver tail and ears flicked with restless energy, so delighted was she to have finally captured a magical girl.
"Get moving already. His Majesty the Demon King is waiting."
Galea unhooked the chain from the wall and took it in hand. When she pulled, Hermes's body was forced upright with it.
"Ah. Before that, one question. Hermes—are you a virgin?"
Of course. Eroge worldbuilding.
"What the hell kind of nonsense is that. A virgin?"
"Never mind. I'll just check myself."
Galea squatted and flipped up the hem of Hermes's skirt.
"Wh-what are you doing! Stop! I said stop!"
Hermes clenched her fists and resisted, but the gap between her and Galea now was the gap between an ant and an elephant.
Her struggle meant nothing. The skirt rose, and her white panties were peeled away.
Galea buried her face between Hermes's thighs and admired her pussy.
"Whoa. Look at this pretty pussy. Pink, plump, a perfect straight slit. Still a virgin, huh?"
Fuck… Showing my pussy to the enemy… This is a disgrace no magical girl should ever suffer…
"Don't look! Don't—hiih!"
I-it touched… Something cold and long just dragged along the cleft of my pussy…
"Insane. I barely brushed it with a finger and the flesh clung to me like it was begging to be fucked. Optimized for half-magical-girl production, this pussy."
"Where do you think you're touching, you sick pervert freak! Die! Just die already!"
Hermes pounded on the dull silver hair until Galea finally pulled back.
"Alright, alright. Mouthy little thing, aren't you. How did a bitch like you ever become a magical girl."
"To beat the shit out of bitches like you. Why."
"Hmm. That so?"
—Smack!
"Hngh—hh…!"
Sh-she hit my pussy… She smacked it…
A mere monster… A beast… hit my pussy…!
A faint heat bloomed where the palm had struck.
She had held back—it did not hurt—but the shame was overwhelming.
Fuck… Getting my pussy slapped… Letting someone else touch my genitals…
Before the heat—pleasure or simple sting, she could not tell—had even faded, Galea seized a fistful of her hair and forced their eyes to meet.
"A lowly human female like you ♡ Talking back to your Master without manners? You'll regret it later ♡"
"Hiiih…!"
Galea's red eyes, wild as an unbroken wolf.
Looking into them, strength drained from Hermes's limbs and her body began to tremble.
I-I'm not scared… When I was a magical girl I fought Galea again and again… I shoved magic into that face and banished her again and again…
It's only that I can't use magic. That's all it is—and I can't even meet her eyes.
Her flesh shuddered like a lamb before a lion. Instinct told her: the being in front of her was one she could never defeat.
"Scared already, little pup. If this much frightens you, what are you going to do. From now on you're going to be free-use pussy for monster welfare, getting dog-fucked all over Gehenna ♡ Say goodbye to that pretty pussy I just saw ♡ Once it's a ruined, gaping mess you won't get to look at it again ♡ Bye-bye, pretty pussy ♡"
Fuck… This goddamn eroge world…
The place she was dragged to was a dark audience chamber with a red carpet laid across the floor.
In the pitch-black dark, the carpet ran toward a great throne, and upon that gold-ornamented seat someone sat.
Hermes had never seen this person in the flesh—only glimpses in photographs and video records.
Even from a distance, though, she knew.
The way those legs crossed as if born to the throne. The powerful, elegant presence that could not be concealed even in stillness. A superior being of an entirely different species.
Human instinct, and a magical girl's experience, both warned her.
That person is dangerous.
"Welcome. To my Gehenna."
Violet eyes fixed upon her. The voice seemed to bypass the eardrums entirely and pour straight into the brain—a voice that transcended human reason.
"My name is Gracia. The great leader of Gehenna."
The woman rose from the throne and approached. Strength left Hermes's legs of their own accord, and she sank to the floor.
With every click of high heels, those enormous breasts swayed. When the dark dress—black as night air pressed into fabric—shifted, hair white as snow moved with it.
"Head of the Earth Invasion Plan. Ruler of ten thousand worlds. Source of nightmares. The Demon King."
Gracia stopped before her, took the hem of the dress at her hips, and spread it to either side.
A gap opened between her legs—and from it rose a black cock thicker and longer than a man's forearm.
"Eh…?"
"And the husband to whom you shall devote your entire life in worship, you inferior cock-sleeve bitch. On Earth, do they not call the one who bears children a wife?"
A cock… eh?
But Gracia is a woman with huge hips…
"Why……?"
A massive member filled her vision. No—even "massive" fell short.
She had possessed one in her previous life.
But the heavy presence of this thing existed on a different plane entirely. Comparing it to the same organ felt almost shameful.
Veins standing out in livid ridges. A huge glans. A shaft thick as rebar.
Even its straight, thrusting shape looked purpose-built to pound a woman's insides, carve them out, and remodel them into a convenient pregnancy pouch.
Looking up from below, its majesty hit her all the harder. A long cock-shadow must have fallen across her face.
Even the black guys' cocks I saw in porn are toothpicks next to this…
"A cock… eh…? A… cock…?"
"Galea. Why is the cock-ornament condom so startled?"
"It would seem she is shocked by Your Majesty's pussy-spanking club."
"Hmph. How pitiful. This body is Gracia, great leader of Gehenna. Whether in the form of a male or a female, tentacles or otherwise—bodily limits mean nothing to me. And yet she cannot even grasp that. Truly a stupid creature. But being stupid, she lacks the wit to disgrace her husband. Fitting for a baby pouch."
While Hermes's mind was still reeling, Gracia rested that cock upon her face.
"Eh… hi… hiii… t-take it offff…"
Heavy… The weight of the cock crushing my face is too much… Flesh shouldn't weigh this much…!
D-dare put a cock on my face… on the face of the beautiful Magical Girl Hermes…!
It may reek of a proud male, but to set something so filthy on my face…!
"Hmph. You are nothing beside me, yet your looks are passable enough. Perfect as a cock-rest, too. Yes. I shall take this human."
The pointed toe of a high heel tapped lightly against Hermes's womb.
"Enter this one as a candidate for breeding-pussy for childbirth."
