The Taste of My Adopted Sister's Pussy (3)
I spread the pussy of my adopted older sister, Dong Ari—a year my senior—wide open with both hands.
Even with her lips pried apart to the point of pain, this airhead bitch didn't notice a thing, far too deep in thought. I'd learned as much across fifteen years of experiments, so I knew it was safe: the women of this household, once they slipped into the Super-Concentration State, couldn't even feel pain.
"My dear sister Ari, did you know?"
I gently eased my magnificent, fully erect cock into her pussy, and the moment my glans made contact with her hymen, it began pressing in, again and again.
"The very first cock in history to touch your hymen is mine, dear sister."
Not some nameless prince on a white horse, you dumb bitch. Me.
Slick─ slick─
I diligently worked my glans against Ari's hymen. It was a pleasure I'd savored countless times before, yet every single round sent a fresh jolt through me. How could it not? In all my experience, she'd stayed locked in the Super-Concentration State for at least five minutes, completely blind to my perverted antics—but what if, one day, it broke without even a "warning sign"?
I'd be thrown out of this house, that's what.
Adoptive Mother might be a blockhead, but she genuinely adored her daughters. If she ever learned what I really was, there'd be no forgiveness.
Fucking bitches. They've squeezed a lifetime of free labor out of me, and they'd toss me out for this?
So consider this justice, ladies. Justified revenge, you two.
After a long, devoted stretch of grinding against her hymen, I shifted my angle and dragged my shaft along the full length of her labia. Using my own sister as a living onahole—the thrill of it was unbearable in the best way.
"You may never see me as a man, dear sister, but under enough stimulation, even your body has no choice but to respond."
I reached out with both hands and seized her nipples.
Tuuuug─!!
And pulled. Hard.
If the Super-Concentration State broke this very instant, I'd take a slap across the face. Just imagining it set my heart slamming—half the thrill came from that.
Oh? Her nipples are stiffening.
Between the relentless friction on her pussy and the abuse of her nipples, they finally stood up. It was true that the brain couldn't register outside stimuli in the Super-Concentration State. But unlike the brain, the flesh still answered to arousal.
Savoring her most secret places in that state, I slid my right hand down and began caressing her clitoris.
"Sis, your clit's standing at attention, you know?"
I whispered it right against her ear, but her eyes never so much as flickered. As if... time itself had stopped around her.
Something about this really is off, isn't it?
At first, I'd assumed the Super-Concentration State was simply a quirk belonging to the women of this house. They would always freeze without the slightest motion—five minutes at the shortest, sometimes a great deal longer. They didn't even blink. Their eyes just... stopped.
Lately, though, I've started doubting that explanation. It's an absurd conjecture, but... what if it's actually some kind of 'psychic power' of mine?
This ridiculous line of thinking began a little while ago, back when I went to see the professor at my university—the one with a campus-wide reputation for being quite pretty. I'd had a question about an assignment, so I stopped by her office, and midway through, I happened to ask her something even she couldn't untangle. She seemed to sink into thought...
...and then didn't move a single muscle for exactly eleven minutes.
She didn't even realize she'd been lost in thought for eleven minutes.
I waited three. She stayed perfectly still, eyes unmoving. That was when I recognized it—the exact same symptoms as the women of my house slipping into the Super-Concentration State. I waved a hand in front of her face, then shouted straight into her ear. Nothing. With my conviction hardening by the second, I decided that if I was going down anyway, I might as well test it properly—and grabbed her breasts.
Nothing. As expected.
Thanks to that, I got a lovely look at what kind of panties she wears every day. Every cloud, silver lining.
And as it turned out, the professor was a virgin, too. Who would have guessed.
Setting aside the women of my own family, it was the first real, live pussy I'd ever laid eyes on, so I got pretty worked up back then.
The Super-Concentration State comes with "warning signs" that announce when it's about to end. When motionless eyes begin to blink, when hands and body start to stir ever so slowly—a moment later, the state dissolves. But there'd been no guarantee the professor's trance matched my sisters' exactly, so I timed my perverted fun to stop at precisely the five-minute mark.
Unfortunately, the professor stayed frozen for six more minutes after that. Her stasis finally broke displaying exactly the warning signs I knew so well. I still remember how bitterly I regretted not getting to indulge a little longer.
Anyway.
It was because of that incident that I began to suspect the Super-Concentration State might not, in fact, be a hereditary trait of this household's women. Driven by a nagging what-if, I combed through every scrap of material I could find. I quizzed professors about similar symptoms. I even asked doctors. All I ever got back was that a human being simply... stopping, like that, was medically impossible.
Which is precisely why I've come to suspect it might be some special 'psychic power' that belongs to me alone.
Haha... but there's no way that's actually it, right?
Psychic powers—in this day and age, where androids and cyborgs exist as a matter of course? Nothing that unscientific could possibly be real. It was a coincidence. Nothing more.
I snorted a dry little laugh.
"Ooh... I think I'm about to blow soon?"
While I'd been toying with Ari's body, the pressure of my climax had climbed right to the edge. I should probably finish onto a tissue...
No. Tissue duty had gotten old. I was craving a different kind of thrill now.
"Hmm..."
I pressed my glans lightly against her hymen.
Pussshhh...!!
One harder shove, and the hymen would tear—and my cock would finally pop its cherry. But the time wasn't right yet. Coming in her pussy would get me caught, one hundred percent. And if she ended up pregnant, forget it. That would be even worse.
Come to think of it, Adoptive Mother—that absolute bitch—is the one who named me Dong Jungnam.
Dong Jungnam. Literally: 'Virgin Man.'
It was the name I was given and registered under after my adoption, and I paid for it my entire life. That virgin bastard who's never even touched a woman. Every sneer I ever earned traced back to it.
Bitch.
Sure, it was true I'd never slept with a woman. But that didn't mean I didn't know what pussy was like. I was rubbing my cock against one at this very moment, wasn't I?
"Dear sister Ari, would you kindly accept my semen with your body?"
I slid my glans slowly down from her hymen and brought it to her anus.
"If I finish inside your asshole, I don't think anyone will ever find out."
With both hands, I wrenched her buttocks apart, prying her anus wide open.
Her lewd little pucker parted gently, left and right.
"Fuck, my heart's going insane."
This was lunacy I was attempting for the very first time. Until today, it had all been rubbing my cock against her pussy, touching it—nothing more. But blood ties or not, the mere thought of coming inside the body of a 'family member' had me dizzy with excitement.
The dopamine is off the charts!
Pussshhh─!!!
I ground my glans against her anus and pushed, harder and harder. It wouldn't go in.
"In that case, I'll just need some lubricant."
I pulled my cock away and spat squarely onto her pucker.
Ptui!!
Then I smeared it around with my finger, dirtying her hole with my spit—and then, for the first time ever, slid that finger into my sister's asshole.
Shloop─!!
"The thrill is no joke. And neither is this grip."
Having far too much fun, I absentmindedly started jamming my finger in and out of her, rough and careless.
Pop~!!
Back out came the finger.
"It'll reek, won't it? ...Huh?"
What the—?
No smell. I'd braced myself for something foul, so why was the only scent reaching my nose something suspiciously like shampoo?
"Oh, right—money. She got the Scented Body Procedure!"
In a world with cyborgs, rewriting a person's natural body odor was practically nothing. So that's why none of the women in this house has ever smelled bad. Not once. All of them had been treated.
"Well, aren't I grateful? Now I can enjoy myself even more."
I pressed my glans back against her saliva-slicked anus. This time, gliding on my own homemade lubricant—
Shloop─!!!
—my cock slipped all the way into my sister's asshole!
"Ohhh~!! So THIS is anal sex!!"
For the first time in my life, my cock was buried inside a woman's hole. And not just any hole—an asshole custom-modified to smell like perfume.
"Holy shit, this feels fucking amazing!"
Sliding further and further off the rails, I seized her breast with my left hand and her pussy with my right, and fucked my cock in and out of her ass.
Squelch! Squelch! Squelch!
Thrusting with that much abandon only sharpened the pressure of a climax that had already been teetering on the brink.
"Ari, take my cum with your body!! Here it comes!!!"
Splurrrt!!
Spurt-spurt─!!!
For the first time in my life, I came inside a woman's body. This crackling rush of pleasure. It felt maddeningly, impossibly good. Naturally it does—I'm claiming the eldest of the three bitches who spent my whole life working me like a slave.
"Ooh... if her asshole feels this good, what on earth would her pussy do to me?"
Every fiber of me wanted to pump her pussy full right that second, but that was far too dangerous. My dear sister was a virgin—getting caught would be inevitable.
"If only you weren't a virgin, I'd have secretly dumped my load straight into your pussy."
Still pouring thick ropes of cum into her asshole, I turned her head gently to the side and pressed my lips to hers.
Mwah.
"Fuck. So sweet."
I'd stolen kisses from these lips plenty of times before, yet no matter how many times I tasted them, they were honey-sweet. For all I knew, the Scented Body Procedure had done wonders for the flavor, too.
And then, at that very moment—
Blink. Blink.
Ari's eyes began to flutter, and her body flinched.
Huh?!
I'm fucked.
I was still mid-ejaculation inside her asshole, and the "warning signs" had just appeared—the Super-Concentration State was about to break!
