Beyond a Female, My Personal Sex Toy
My mind felt hazy, as if I were under a spell.
What was it that I needed to do right now?
Whenever such a question flickered through my brain, a clear answer would descend upon me.
Suck that hideous thing in front of you.
“Bae…”
Just before the tip of my tongue touched the object, my sister slowly stroked my hair.
There was a slight pressure in her touch.
“Runi, do you know what you’re about to suck?”
“Uh…?”
“You have to know exactly what you’re sucking. Come on, say it with your own mouth, Runi.”
“This is…”
I knew exactly what word she wanted to hear.
However, it just hovered in my mouth, as if it were a word I could never, ever say.
“Come on, what our Runi is about to suck is a cock. Repeat after me.”
“Co… ock…”
“Yes, you’re sucking a cock. What are you sucking?”
“Cock… cock… I’m sucking it…”
The tattoo on my lower abdomen glowed as brightly as the massive shadow cast upon my face.
It felt as though a sense of duty had been born within me, compelling me to do whatever she commanded.
“Suck it deliciously.”
“Yes… cock… I’ll suck it deliciously…”
Dazed, I stuck my tongue out long and tapped the tip of the cock.
Along with the sticky sensation, a deeply bitter taste hit my tongue.
“Slurp…”
“Ugh…”
As I licked the liquid pooling at the tip, more flowed out, forming droplets.
“Slurp… slurp, slurp… slurrrp♡”
“Looks like my cock tastes good, Runi.”
No matter how many times I licked it, sticky droplets would form again and again in no time.
“Now, let’s try sucking it.”
After licking the tip, I opened my mouth wide and slowly took the cock inside.
“Mmmph… ghhnn!”
Even though I opened my mouth as wide as I could, it was a struggle to swallow her cock entirely.
Just when I thought I had reached my limit, there was still half of it left outside.
“It seems this is your limit. It’s okay. It’s your first time, after all.”
She stroked my hair as if to praise me for a job well done.
That touch stirred a sense of pride from deep within my heart.
“Slurrrp… slurp! Slurrrrrp♡”
“Don’t use your teeth, just go slowly. Yes, just like that.”
When I had swallowed about half of it, I could feel the tip reaching deep inside.
More intense than the bitter taste lingering in my mouth was the thick, erotic scent that filled the air.
Every time I struggled to catch my breath, that scent seemed to fill my entire head.
“Try moving a little faster.”
That single command acted as a stimulant.
“Slurrrp♡ Slurrrrp! Slurp… slurrrrp♡”
“Hnnng…!”
No one had ever taught me how to suck a cock.
Yet, it was as if I had known how to do it perfectly from the start; my lips tightened, and my tongue busily wrapped around the shaft.
Every time I looked up at her face while sucking, she wore a light smile, her expression one of pure pleasure.
“Slurrrrrp♡”
I tightened my lips once more, pulled my head back, and then thrust it forward quickly.
“Ugh…! Runi…!!!”
—*Splurt!*
Along with her voice calling out to me intensely, thick semen gushed out from her cock.
There was so much of it that it was on the verge of spilling out of my mouth and nose.
“Mmmph?!”
Just as I stiffened in panic, she pretended to stroke the back of my head while subtly pressing down on it.
“Mmmph…”
“Runi, swallow it all. Don’t spit it out.”
Her words carried an undeniable, coercive weight.
My throat moved on its own, focusing on swallowing the endless stream of semen.
“Gulp… hnnng… mmmph…!”
I managed to swallow the semen that was overflowing from every hole in my face, and then I slowly pulled the cock out of my mouth.
Then, thick, viscous semen dripped heavily from the tip.
To think she could ejaculate so much and still have more.
“Did you swallow it all? Open your mouth.”
“Bae♡”
I opened my mouth wide to show her clearly that there was no semen left inside.
“Good girl, Runi. You have to listen to your sister like this to be a good little sister.”
Before I knew it, she was drenched in sweat, her hair disheveled.
It seemed she had felt quite a lot of stimulation while having her cock sucked to that extent.
She grinned and snapped her fingers.
Suddenly, a sharp headache flashed through my mind, and I became acutely aware of my current state.
The acts that had been accepted so naturally just moments ago were now mixed with a surge of immense shame and a desperate wish that this was all a lie.
“Aaaaaah!!!”
I collapsed on the spot with a strange, pained cry.
“Runi, was sister’s semen delicious?”
“I, why am I…”
Just as I couldn’t believe what was happening, her fingertips touched my skirt.
Something pulled at it forcefully, just like when my panties had been stripped away.
In the end, I was left completely naked, just like her.
“I wonder what Runi’s pussy tastes like.”
Saying that, she leaned in close and rubbed my vulva with two fingers.
“S-stop it…!”
The moment I tried to push her away, something black appeared and bound my wrists tightly like handcuffs.
Against my will, my arms were raised high above my head.
“Since Runi made sister feel good, sister will make Runi feel good, too.”
“S-stop… mmmph!”
Her lips covered mine, preventing me from saying anything more.
The fingers that felt like they were about to enter me pulled away from my vulva.
The new point of contact was my clitoris.
“Slurp… slurp…”
“Mmmph…”
While being kissed by her, I had to watch as her two fingers moved over my clitoris.
Because my own arousal fluid was already coating her fingers, the sensation of her touching my clit was incredibly smooth yet sticky.
“Slurrrrrrp♡”
“Hnnng?!”
Her tongue suddenly wrapped around mine, teasing it before quickly pulling away.
A long, thin thread of our mixed saliva stretched and then snapped; I felt as if my sanity had snapped along with it.
“Haa… hnnng…”
“If you make a face like that just from a kiss, how is sister supposed to hold back? It makes me want to turn you into my personal sex toy right now.”
“Sex… toy…?”
“Yes, a sex toy. You’re going to go beyond being a female and become my personal sex toy.”
—*Squish! Squish!*
Her fingers rubbed my clit firmly.
“Hyaaaah♥”
A moan burst from me before I could stop it, and soon after, I watched as my clitoris began to swell.
—*Press! Slide!*
As she pressed down hard and lightly tapped the clit with her fingertips, the hood peeled back, revealing it in its entirety.
“Your clit has gotten so plump.”
Her other hand moved.
That hand pressed down hard on my lower abdomen.
“Hnnng♥”
“What’s that sound? Sister only pressed your lower abdomen.”
Just as she said, she was only pressing my abdomen while touching my clitoris.
Yet, a moan erupted as if she had stimulated a sensitive spot.
“Runi, you see… I really wanted to eat your small breasts.”
“You… you already ate them earlier…”
“Runi, just because you’ve eaten something delicious once, does that mean you don’t want to eat it again?”
She asked a question that already had a set answer and began to suck on my breasts.
“Slurrrrrp♡”
“Huuuh-ghhh♥”
A stimulation stronger than before washed over me.
—*Squeeze!*
Whenever I tried to focus on the sensation of her sucking my breasts, I found myself focusing even more on her cock, which was pressing firmly against my lower abdomen.
Where the tip of her cock passed, sticky semen painted a picture.
“Slurp… slurrrrp♡”
“Hyaaaaah♥ Wait, don’t pull on it…”
Just as I was complaining about the sensation of her biting and pulling on my nipple with her lips, her mouth pulled away.
She seemed to be savoring the taste of my breasts, smacking her lips.
“One, two, three.”
Suddenly, she began to count, and a tattoo identical to the one on her lower abdomen appeared on mine.
“Hmm, that’s it. Contract successful.”
A contract? This?
The contract with a familiar that I knew wasn’t like this.
—*Squish!*
“Hyaaaat♥”
Suddenly, one of her fingers burrowed into my vulva.
“My finger feels like it’s going to snap. If your pussy is this tight, you can’t be sister’s sex toy.”
“Ugh… hnnng…”
“Come on, Runi. Where did sister just put her finger?”
“Ugh, my vulva…”
“Wrong. It’s a pussy. Just like you said ‘cock,’ why don’t you say ‘pussy’ too?”
As her fingers moved inside me, the tattoo on my lower abdomen began to glow with an increasingly intense light.
My mind felt like it was drifting into a haze once again.
“Pussy… my pussy… is it tight?”
“Yes, it’s tight. But sister will stretch it out for you. So that you can become my personal sex toy.”
—*Squish, squish, squish! Squish!*
“Hyaaaaah♥”
One of her fingers began to rummage through my pussy at a very high speed.
She even curled her finger to press firmly against the vaginal walls, causing arousal fluid to spray in every direction.
“S-stop it, haaaah♥”
“It’s only just beginning, Runi.”
—*Squish!*
“Haa-hnnng♥”
Soon, another finger was added.
Now, two fingers were moving in circles inside me, thrusting rapidly.
“Feel sister.”
With those words, she pressed down on my lower abdomen.
The pressure from above made her fingers feel even more overwhelming, but I felt no pain at all.
Only intense stimulation existed, like the glowing tattoo.
“Hnnng… hyaaaaaah♥”
—*Spluuurt!*
Along with a vibration that seemed to resonate through my lower abdomen, a massive amount of fluid erupted from my pussy.
My legs spread wide as if trying to expel even more.
I arched my back completely, trembling violently, before collapsing in a heap.
“Hnnng…”
“I think this is enough.”
“Enough…?”
I lifted my head with great effort.
—*Press! Squish!*
The tip of her cock was rubbing against the entrance of my pussy.
“You know, a demon’s sexual desire transcends that of a human, right?”
—*Thrust!*
“Hooo-gooooooh♥”
As her hideous cock entered all the way to the root, I let out a very lewd sound.
