Coming to an Agreement (3)
“……Ah.”
With a soft thud, I laid my cock across Lottie’s stomach. It was already fairly hard, and there was a faint sting to the contact, but—
“Haa…”
Even that unpleasant sensation was on the verge of dissolving into pure anticipation the moment I looked down at the heat written across her face.
I hadn’t wanted her to see me ruled by lust. But how the hell was anyone supposed to hold this back?
I bit my lip once, just enough to claw back the bare minimum of reason, and looked at her.
“……Don’t stare so hard.”
Charlotte still had both wrists pinned. She turned her head slightly, trying to slip out from under my gaze.
Her little sister’s body, bare of so much as a thread, was almost unbearably provocative. Sweat-damp light-blue hair clinging to her skin. The pale stretch of her underarms and collarbones. Her breasts. The stiff peaks of her nipples. That slender waist.
“Don’t regret this, Lottie.”
“……Nnh.”
I spoke low and brushed her hair back with gentle fingers. When I swept aside the bangs veiling those lovely blood-red eyes, Lottie twisted her mouth on purpose and looked up at me like a challenge.
“You don’t regret it either, Brother……. Now that we’ve come this far, I won’t forgive you if you try to run.”
“…….”
I didn’t answer. Of course I had no intention of bolting at this point.
Ethics, morals—set every petty little problem like that aside, and I still had no decent way to cool a body already burning this hot.
“……I’m really going to fuck you, so don’t bother asking twice.”
I brushed the pad of my thumb over her soft pink lips and dropped my voice. Lottie gave a short laugh and lifted both legs.
“Then this is an agreement, right? Brother.”
“……!”
She locked her thighs and calves around my waist as she murmured it—a gesture that said, plain as day, that she had no intention of letting me go now.
And if she actually used her strength to pin me, there wouldn’t be much I could do about it.
“……Hah.”
I flinched for a second, but as I’d said, I wasn’t planning to escape. I only frowned at my little sister’s cheek and closed a hand over her breast.
It was small, almost dainty—but that had nothing to do with it. The simple fact that I was gripping one of Lottie’s most sensitive places was enough to set me on fire.
We’d already come this far.
Holding back any longer was more than I could manage.
I took hold of myself at once and slowly angled toward her entrance—
“……Hah. Put it in already, Brother.”
Lottie twitched the corner of her mouth in a show of bravado and spread her legs wide.
I decided to grant her wish.
When my little sister was begging this desperately to be filled, ignoring her hardly seemed like something a proper older brother ought to do, did it?
Complete nonsense, of course. But thinking of it that way made it easier. What did it matter?
I waited a beat with the head of my cock nestled against her slit.
“What, getting cold feet at the last second? Hn—ah—?!”
The moment she tipped her chin up with a mocking little smile, I drove my hips forward hard.
Shlick!
I’d lined us up so that the slightest movement would take me inside her.
“Hegh—nnh—mheh—”
My swollen cock forced its way into her lower lips, and she cried out at the foreign pressure carving into her body.
If I said that sound was beautiful to hear, did that make me a bastard?
So I really went and did it.
I thought it with a strange calm. Of all people, the first woman I ever slept with turned out to be my own little sister.
My head spun into a knot all at once, throbbing like an alarm bell—
“……Haa…….”
—but there were things burning so sweetly through my whole body that they drowned every last scrap of it out.
First, the sheer sexual pleasure. The taboo of rolling naked with my sister. And this aching tenderness toward Lottie that I’d spent so long trying to look away from.
All of it swept aside the psychological obstacles that had been trying to tangle me up.
Above everything else was the look on Lottie’s face as she took me into her body—melting, undone.
“Brother—hah—hyehk…….”
“…….”
And that fevered voice of hers reduced every stray thought to nothing at all.
……Honestly.
I had no choice but to swallow a hollow laugh.
In every possible way, she was a little sister built to drive a man insane.
That was the whole of it—and the truth was, I didn’t seem to need anything else. Not for this. Not while I was sharing myself with Lottie like this.
“Kh…….”
I groaned as her walls clamped around my cock with a dense, sticky grip.
I was melting under the heat too. A feast of pleasure I’d never felt in my life.
It was so fierce, so sharp, I wondered if joy like this even existed anywhere else in the world.
If my focus slipped for even a second, I felt like I’d spill white right then and there. Being inside Lottie felt that good.
Slick fluids and sweat clung between our sexes, our stomachs, our thighs, and every shift of our bodies made wet, filthy sounds.
The slap of skin on skin was obscenely lewd, and it frayed what little reason I had left.
“Hyak……. Hauh—eup—hgeuk?!”
Whose sweet flesh-scent was this, really? With Lottie’s cries cascading one after another as my backdrop, I entertained the idle thought.
The faint lavender mixed through it was, of course, the scent she usually wore.
“Huu…….”
I exhaled a breath gone madly hot and shoved my bothersome bangs back.
There was no need to keep holding her wrists anymore. She was the one who’d seduced me first. As if she was going to run.
“B-Brother—I—nnh—this feels—weird……! Hyaang?!”
Right now, the only thing worth focusing on was devouring Lottie’s body. Taking her. Claiming her.
I ignored even the desperate, ringing plea in her voice.
There was no stopping now.
“……Sorry. I can’t stop.”
“Ukh—hehk……!”
She clung to me in a panic and raked her nails down my back. I twisted that pain into more stimulation and crooked my mouth.
“Bro…ther…….”
Her blood-red eyes, wet and shining, held my face with something almost pitiable.
Not content with clawing me, she sank her teeth into my shoulder with a sharp little bite and poured a melting voice straight into my ear.
“……I—I……”
Trying to negotiate again, was she? I had zero intention of stopping either way, and I was about to brush her off lightly once more when—
Lick……!
“?!”
Lottie suddenly dragged the tip of her tongue along the shell of my ear, then shoved a voice gone filthy and low straight into it.
“……If you’ve enjoyed yourself enough, hurry up and cum inside me. Your semen, Brother.”
“……!”
“You can thrash your hips like a dog in heat all you want. You’re still in the palm of my hand. You know that, right?”
Crazy.
I swore for real. The way my little sister flipped her tone in an instant—that single cynical line—was obscenely erotic—
“……Kh—ugh!”
I couldn’t hold back the climax that surged up in a flash. I crushed Lottie against me—
“Ahah…….”
—and with thick, pulsing surges, every ounce of strength drained out of my body as I poured the white that had climbed my shaft straight into her depths.
I fought to steady my suddenly ragged breathing and looked at her.
“Haah—huuuh…….”
She wasn’t exactly unscathed either. Her face was flushed more than a little—but even so, those eyes that trembled through the aftershocks and slid a sly glance my way…
Whatever that blood-red gaze meant, it was probably:
—Just as planned.
“…….”
“Haa…….”
My mouth shut on reflex. My eyes fluttered, but Lottie only wore a bewitching little smile, as if my reaction barely mattered.
“……Brother.”
She called me next. Her voice was still panting, and her body kept giving intermittent twitches as if she too had peaked—but the clear difference between us was, without a doubt, endurance.
“You came…… inside your little sister?”
“…….”
“How was it? Satisfied?”
Lottie curled her lips in a mocking smile, and some nameless feeling jabbed through me hard enough that I stiffened again below at once.
I’d just emptied myself once. There was no way I should already be this ready again.
“Oh…….”
While I was still scrambling to master the shock, Lottie let out a meaningful little sound of wonder.
Her gaze was fixed on her own lower belly.
……Right. My cock, which had conveniently swollen back up, was still buried inside her.
“Still nice and hard, aren’t we? My brother.”
“……No—wait.”
“How about it? Want to go again? I’m fine with two rounds, three—as many as you like…….”
She dragged her tongue across her upper lip and gave me a coquettish, smiling look. An unidentifiable chill slid down my spine, and I had to swallow dryly.
Something—some withered, mummy-like vision—flickered through the back of my mind.
……That couldn’t be my future, could it?
Nah.
No way.
“…….”
In the brief silence I felt my mouth go bone-dry. I grabbed Lottie’s waist at once, meaning to pull out—
Clamp!
“Ah-ah. Where do you think you’re running off to?”
“……L-Lottie? I just—something urgent suddenly came up—”
“Lying isn’t allowed, big brother.”
Lottie beamed as if the idea were absurd.
She seized my wrist hard enough to crush it, then aimed a single short line at me.
“Brother.”
“…….”
“Get in position right now—unless you want to be wrung dry all night until you die.”
“Yes, ma’am…….”
