Real First Experience
Was this the order that had always been set?
Or was it a situation that applied to me alone?
Either way, one thing was certain — I would not know the answer until my full six months of imprisonment had run their course.
Which meant I had to choose now.
"What are you doing? Hurry up and do it."
The reality I had awakened to in the training room.
I had to show the guard standing before me the state of mind I carried now.
Honestly speaking, I could not swear that I had cast everything aside.
Unlike Inmate A522, who moved the instant an order was given, hesitation still lingered in me even now.
I may have grasped my place in the training room, but I was still a long way from perfection.
Even so, I had to show the best I was capable of expressing in this moment.
There was no room left to deliberate — only the resolve I had carved into my heart, and the determination never to put on airs in front of him again.
"Lord Leviathan. I… Inmate A713 am trash who lost to lust. Because I have not yet properly received the guards' education, I behaved insolently! I will become a prisoner you can use whenever you please! So please… forgive me…."
I swore my submission.
And I expressed it with my body as well, pouring every scrap of sincerity into the gesture.
Propped up on my bound hands, I squatted with my legs spread and offered up the shameful place between them.
The ring attached to the rotor peeked out from between my folds, swaying in the slick wetness of my crotch.
An act I could never have performed in ordinary life.
No — an act I might never have performed in my entire life, had I never come here.
I showed it of my own will.
"Hmm. Clever. Mixing in the prisoner's oath for effect, are we?"
"Th-that's not it. I just… I really… I don't know if it's everything yet, but I truly mean to cast it all aside… and obey… so…."
"Enough. No need to ramble on."
Fortunately, Leviathan seemed to recognize my sincerity.
He rebuttoned the cuff he had undone, ending the violence, then straightened his clothes and stepped toward me.
"By the way…."
But not everything had been resolved.
Leviathan came right up to me, crouched down, met my eyes, and reached out a hand.
"Yes…? Nngh…! Haa…!"
"You're holding this ring out because you want me to pull it free, right? A713?"
"That's not—!"
"Lift your hips. Don't let your ass touch the floor until I've pulled this out."
"Yes!"
He flicked the rotor's ring dangling between my legs with a fingertip.
The rotor was still stuck fast against the inner wall of my womb.
Whether it had some kind of suction function or not, no amount of clenching my lower hole would dislodge it — and every time Leviathan toyed with the ring, it sent faint vibrations through that hypersensitive place.
"A713."
"Yes…!"
"You're a virgin, aren't you?"
"…Yes. That's correct. Though my hymen has already been torn…."
What was he planning?
Leviathan repeated the fact he had already uncovered yesterday while toying with the ring.
For a long moment he simply stared between my spread legs.
The situation was oppressive and mortifying.
With his gaze fixed on such an intimate place, shame flooded through me.
I wanted nothing more than to close my legs, but I held still.
The reason was simple.
I was a prisoner, and he was a guard.
That was all.
"Right. Hah. Good. Hey. A711."
"Yes."
"I'm authorizing you to speak. From now on, sit behind A713 and massage that bitch's breasts. It's her first time, so it'll be rough. Play with her nipples a bit, kiss her some, get her worked up."
"Understood."
Leviathan called over A711, who had been standing apart, and issued the order.
At the same time he hooked his finger through the rotor's ring and, with a casual tug, pulled it free.
— Schlurp.
"Nngh…! Haaang♡"
The pleasure that had been coiled tight under the weight of the atmosphere and the situation came spilling out.
The rotor slid free from the suppressed stimulation that had built up alongside my lust.
The place it left behind felt strangely empty.
"Luckily you're still wet. Good. A713."
"Yes… Lord Leviathan."
"From this moment on, you are my onahole. Do not come before I do. Under any circumstances."
"Ugh… yes. Understood."
"It's your first time. It's going to hurt a lot."
"Yes…? Haaunn!"
With a single sentence from him, I became a human onahole.
Toward the place the rotor had vacated, Leviathan approached with his trousers already undone.
Between his legs, a pillar was rising in small, twitching surges.
The thing called a cock.
Veins stood out stark along its length….
"Ah! Th-that, nngh…!"
Somehow the shape and size did not feel unfamiliar.
It looked exactly like the dildo I had struggled so hard to suck and lick earlier.
Had that dildo been modeled on Leviathan's?
The long shaft, curved upward like a bow, vanished from sight in a fraction of a second as it drove into me.
At the same instant, searing pain exploded between my legs.
"Kyaaak!! Ah… aaagh!!"
His cock forced its way into my forcibly spread pussy.
Without proper foreplay or any preparation whatsoever.
His cock, driving in one-sidedly, was far too large for a first-timer like me to take.
I scraped at the floor with my bound hands behind my back and clenched my teeth.
Tears of pain I could not master were already spilling from the corners of my eyes, and foam threatened to burst between my tightly sealed lips.
"…Calm down. Lean back against me. Relax. Nice elasticity in these breasts. Here. If I touch them like this… a little better, right? Hmm. Soft body. Just let the tension go and you'll be fine."
Behind me, A711 drew close.
She gathered my arms — the ones struggling to hold me up — into her embrace, and a moment later she was supporting my entire weight with her own body.
Naturally I ended up leaning into her, and following Leviathan's orders she began fondling my breasts, brushing her lips against my earlobe, hunting for the erogenous zones hidden across my skin.
At the same time she locked her legs around me so I could not resist.
— Schlick.
"Kyaaaugh!! Haaunn!! Ah…. It hurts…!"
Completely helpless.
Leviathan put power into his hips and shoved his cock deeper.
Under that fierce force I trembled violently, mouth hanging open, shuddering from head to toe.
In pain I could neither escape nor transform into pleasure.
All I could do was be used.
"Guh…! Ah… aaugh! Kh…!"
"Hmm. Definitely tight. A711. She's far too dry. Loosen A713 up before my cock goes soft. Hurry."
"Yes. Understood. Now… A713. Where are your sensitive spots? Here… your sides seem a little weak, how about that? Your nipples are responding nicely too… anywhere else?"
Through the agony, a man's voice and a woman's voice shook my already reeling mind even harder.
Especially A711's voice murmuring at my ear — it sounded like a devil's temptation.
A reality I could not escape anyway.
It only sounded like she was telling me to offer up my weaknesses myself if I wanted to enjoy this.
That kind of temptation.
I absolutely would not fall for………………I had no choice but to fall for it….
I already had no options left, after all.
Before any pathetic scrap of pride could rise up, I offered my weaknesses of my own accord.
Because this was my first time being taken by a man, I named the places I usually touched when I masturbated.
"Nngh…! Yes. My sides and… my nipples… and the nape of my neck… when I press a vibrator there while I touch myself… it feels so good… so. Haaunn!! ♡ Haaang…!"
"That sound… nice. Mmm… slurp… haa. Does it feel good when I lick you like this?"
"Hic!♡ Mm… it feels good."
Stimulation beyond anything I had ever felt in ordinary life flooded through my body.
The instant A711's tongue touched the nape of my neck, a jolt of electricity made me flinch without meaning to.
I didn't know why, but the pain radiating from my lower abdomen seemed to ease a little.
Was this what they meant by relaxation?
And then an act I had never been able to perform during masturbation.
The moment two hands kneaded my breasts while a new sensation joined the one in my pussy—
Compressed heat erupted from the back of my throat.
"Haugh…! Heeung♡… nngh…!"
A voice so shameful it crossed into contemptible — the voice of a female slave — burst past my lips.
And in that instant.
Sensing something, Leviathan began to move his hips slowly back and forth.
The sight of his long cock withdrawing, glistening with my juices.
And the brief glimpse of the root and shaft.
A small emptiness swirled between my legs, leaving a hollow sensation in its wake.
Not enough.
Something felt empty.
Wanting to be filled again.
I bit my lip.
Even knowing it would hurt when his cock pushed back in.
I met his eyes and let him see that I was ready.
"After putting on every kind of airs, heh heh. That expression is adorable. A713. How does it feel?"
"Uuu…."
— Smack!
"Is that how you answer me?"
"…Haa… I'm sorry. Lord Leviathan."
I took a slap across the cheek for failing to answer properly out of sheer tension.
But this was a different kind of slap from the earlier violence.
The moment a pain just sharp enough to sting settled on my cheek—
I felt a gush of wetness spurt from my lower hole.
A masochist's conditioned reflex.
Then A711 kneaded my breasts roughly, and the strength drained from my body.
"Kyaaugh…! Ah— aaa…! Uuung♡ Haaaa—!"
Seizing that exact moment, Leviathan's cock drove back in.
It sank deep until it met the root, filling me all the way to the wall of my womb, then twitched inside and spun a strange pleasure through me.
The fingers that had once torn my hymen.
A fullness greater than that spread outward from inside my womb.
Pleasure born from the trembling of sex toys and the entirely different twitching of a living cock.
Suffering and a lewd sensation felt in a situation I could not resist.
Floundering in arousal and pleasure, I was used.
Exactly… like an onahole.
"Hmm. Nice and tight. Hmm!"
"Uha… uh… uhik!♡ Haugh… uuugh!"
After that it was pure repetition.
Reading my reactions, Leviathan rolled his hips forward and back, adjusting the force of his cock.
I was fucked, and fucked, and fucked again.
"More…! Harder… haunn… put it in. When you pull out… I hate it…! Haunn…♡"
Whenever his cock withdrew and the emptiness hit, I was the one who begged first.
But the price for that was another slap.
— Smack!
"Who does an onahole think she is, making requests? You're just here to be used. I went easy on you because it was your first time — don't get ideas above your station."
"Nngh haugh…! Yes! Yes! Lord Leviathan…! Haugh…! Ang♡"
Even so, it felt good.
A rich satisfaction I was tasting for the first time.
And a mind that melted further and further, filling up with pleasure.
So this was why people craved sex.
"Slurp… hnn… haa. Mmm… A713… feels good, right? I like it too…. Haa. Hmm…."
On top of that, A711's switch had flipped — her whispers and caresses piled on until I truly could not keep my head straight.
It was clearly agonizing.
And exhausting enough that I wanted it to stop.
Yet mixed in was the wish that the pleasure would never end, leaving me stranded in a place where I could choose neither.
Well. Even so.
I was a prisoner.
No — right now I was an onahole being used… so even thinking that was a luxury.
But then the moment came when my body accepted pleasure right up to its limit.
The heat in my flesh spun a strange sensation into being.
This feeling. Ah. This is… this is—!
Every scrap of will gathered into one point and drove me to the extreme.
"Kyaaugh!! W-wait…! Aaugh!! S-stop…! Ahhk… hhk!! Lord Leviathan…! I-I think I'm going to come!! I… I-I'm coming…!! I'm going to come!! Ah… th-that… stop…!! Please let me come…!! Please!! Please!!"
"A713. Hah! I clearly told you not until I come. Hah! Hold it."
"Aaaaaagh!! Uaa…! Haugh…!! Ah… no!! Nngh!!"
Was it because I was still unused to sex and had let my guard down?
The excitement that had been building little by little finally dragged me to the very threshold of climax.
In truth, the signs had been there.
Even while I was being fucked without pause.
I had wondered why Leviathan was moving his hips so slowly.
The times he pulled his cock all the way out to cool me down — I had mistaken those for a technique meant to leave me aching.
But now that it had come to this, I understood too late that every single act had been a buildup for this exact moment….
"Uh… uaa…! Ah… hauuu…! Haunn…! Haa. Haa.…! No! Ah… no!"
Pleasure or not, my head felt ready to split open.
The sensation right before climax that, during masturbation, I could simply release—
Now felt like torture.
"Hmm. Getting quite tight. Hah! Hah!"
"Kyaaaugh!! Ah… no… nooo!! Aaaa…!"
Was it to torment me further?
Leviathan's hips sped up.
The burden on me, and the rising surge of boiling excitement, both intensified in equal measure.
"Ah… no!! Ahhk…! S-stop…!! Let me go!♡ At this rate… haunn!"
I couldn't hold it.
This was not something willpower could possibly contain.
Impossible.
The words stacking up in my head were nothing but negatives.
Had I lasted a few minutes? A few seconds? Or nanoseconds…?
"I can't!! Ah… I'm coming!! Aaaagh!!! Kyaaaaaagh!!♡"
In the end my body, past its limit, climaxed with no regard for my will.
White fluid jetted from my urethra like a fountain, and I came apart with a scream.
My head emptied out.
In that stupefied haze—
Aaaah— what is this.
…It feels good.
"Heh. Well now. Failed by a few seconds. Hah—"
Leviathan's voice rang through my hollowed-out ears.
And in my womb.
Something was sliding down along the walls of my vagina.
Thick and sticky.
That kind of fluid.
