Making the Agreement (1)
“Wait, wait, wait, wait, stop, Lottie.”
I frantically waved my arms to stop Lottie. She had lifted the hem of her shirt just enough to peek at her underboob, then hesitated.
“What?”
The short, blunt reply somehow carried a hint of irritation.
Well, no, that wasn’t a misconception. Until a few years ago, I was used to seeing that cool, piercing gaze fixed on me.
I swallowed hard and chose my words carefully. I had to talk Lottie out of this no matter what.
“……Of course, according to imperial law, close relatives marrying isn’t prohibited, but—”
And in the narrow window of legality, I found the best justification.
I kept my voice steady and calm as I reached out and continued.
“But you know it won’t look good to the people around us, right? Even if it’s legal, social perception is—”
“……Oh, really?”
But it wasn’t the kind of excuse that would work.
Lottie cut me off with a sharp laugh and twisted her lips in disgust.
“Telling me the obvious again—how thoughtful. I thought you thought I didn’t know these things, big brother.”
“……”
“I said I was thinking it through. Do you really want me to back off? Your big brother.”
“Wait—.”
I scrambled for another option, but this time I wasn’t given the chance.
Thud!
The palm that sliced past my ear slammed down hard on the headboard beside the bed.
I stared at Lottie with wide, shaken eyes—
—and she painted a cold smile across her face, the flush of anger on her cheeks.
“……Stealing your sister’s first kiss and then trying to back out? How annoying.”
“No, that was you who—”
“Shut up. I’ll bite you if you don’t.”
‘Meeow,’ Lottie revealed her small white fangs, threatening like a cat. The mismatched expression clashed with her tiny figure, yet it was somehow adorable. I broke into a cold sweat, desperately trying to control my racing heartbeat.
How on earth was I supposed to deal with this heart that wouldn’t stop pounding?
It was almost enough to make me want to cry, but Lottie simply pulled her shirt off again with a cool smile.
The sight of her shedding the garment carelessly filled my vision.
“……”
Lottie’s flawless, smooth upper body was completely exposed, bathing my sight in white perfection. Clean, flawless, and yet so soft—my sister’s bare skin.
I unconsciously swallowed. Just as I was about to glance away, I felt a meaningful sound escape her throat.
“……Hmph.”
She narrowed her eyes meaningfully, then shot me a strange look.
“Heh.”
Next, she burst into a light, mocking laugh, as if everything in the world was ridiculous.
“Really, you’re transparent, Onii-chan.”
“Eh……?”
“You whine ‘I don’t want to’ with your words, but your eyes keep dropping lower.”
“……Ah. That’s—”
“Does it feel good? Want to take off my underwear, Onii-chan?”
Lottie immediately went further, hooking her finger into the strap of her bra with a suggestive pull.
I nearly had a heart attack, and she smirked, delighted by my expression.
“Good. At least you’re not completely heartless.”
The moment I heard that, my mind snapped back.
Insane woman—what was I doing, staring at my sister’s body like an idiot?
“R-Lottie, I—”
“Hah!”
I raised my voice to end this as a harmless incident, but the moment was gone.
Splash!
“Ah.”
It was meaningless. Before I could react, Lottie yanked my arm and pulled me toward her. My hand touched something I instantly regretted.
And in that moment, I understood the irreversible reality. A groan escaped me.
I was finished.
……It was over.
I stared at her in despair, and Lottie gave me a slightly embarrassed, bitter smile.
“Even though this is coercive, it seems you don’t mind. Your body is already responding anyway……”
“……”
“No, if you really don’t want me to, then I’ll wait and seduce you properly. But you don’t seem to be the type to reject me?”
“……”
“……So does this mean I’m innocent no matter what? Big brother.”
She spoke with a bright voice, but I read the triumphant glint in her eyes.
……Even my beloved sister thought I might reject her outright?
But once I started, I couldn’t stop. I figured it was fine since I wasn’t actually refusing. And that’s how it all ended up here……
“……”
Ah.
‘Aah……’
I was truly losing it. Why was she doing this to me?
My head started to ache terribly.
I had tried to treat her as my sister for so long—
—after five years of holding back—
—five years of living as family with her—
“……Lottie……”
“Hmm?”
“……”
I called out to her in a drained voice, then fell silent.
I didn’t know what to say next.
Lottie was wiggling her hips, reaching for the buckle of her skirt as if she wanted to strip completely.
I was supposed to be the cold one, yet I couldn’t stop my desire from rising. Either way, I had no answer.
I gritted my teeth faintly and looked at Lottie with clear eyes.
I stared at the emotions clearly displayed on her face—affection and lust mixed together, the tension hidden between them, the faint fear.
……Was it fear of being rejected?
‘What should I do?’
My head knew. I should push her away now, sit across from her, and preach about the morality of this act.
‘How…… could I……’
But my heart refused to obey.
I was complicated in every way too.
Would crossing the line and stepping over it really be the right thing to do? Even if the law didn’t forbid it, doing something like this with my sister……
“……Onii-chan.”
“……”
Lottie slowly sat up, then asked with a glance at me.
“Are you… angry……?”
The bold attitude from before vanished, and she let out a few hesitant words.
“I just… because you knew my heart…… Yeah.”
“……”
“If you really don’t want it, tell me now. I won’t stop thinking of you, but I can still be a bit considerate……?”
By the time we reached this point, I was having trouble holding back.
I bit my lip hard and immediately grabbed Lottie’s shoulder, pushing her down with force.
A flicker of fear crossed her face for a moment—
—but I wondered if this was even what she truly wanted.
“……Eh?”
I honestly didn’t know anymore.
Now I really didn’t know.
Okay.
I had to just do it.
“Lottie.”
“Onii-ch—”
“You started the seduction first.”
“Eh, eh?”
“……I’m not wrong.”
“……”
Lottie’s lips pressed into a straight line, and a blush bloomed on her pale cheeks.
Our positions flipped 180 degrees. After I pushed her, Lottie lay back on the bed and looked up at me expectantly……
I forced her wrists down, then finally hesitated.
Was it okay to do it? Morally, ethically—my head was full of every kind of worry.
“Onii-chan.”
“……”
“Want me to touch your chest……?”
The very next moment, Lottie’s words pushed all my worries away.
“……You really……”
She poured oil on a burning house—Lottie.
I laughed bitterly and finally gave in.
“……Ugh!?”
I immediately covered her lips. I didn’t give her a chance to breathe or prepare; I simply forced it.
I pried open her lips and pushed my tongue inside. Unprepared, Lottie trembled, her long lashes fluttering, and her wrists flailed where I held them.
But I had no intention of letting go.
She was the one who started it, wasn’t she?
Even trying to escape now was too late. It was just too late…
‘She’s really—’
It was obvious. I was her brother who could have easily raped her with force, yet here I was, unable to push her away.
Even as my eyes twitched, I secretly relaxed my grip, showing panic, but her tongue moved obediently, mixing with my saliva.
The happy expression on her face proved her true feelings.
I felt my body going limp, yet strangely, I savored the lewd satisfaction building in my lower body.
My mind slowly grew hazy.
I no longer wanted to think. I just wanted to chase, drink, and claim this bizarre, impossible Charlotte.
“……Fuh, haaaah……”
After a long, deep kiss, I moved my hand to her lower body, still half-dressed.
Click.
I unfastened the buckle that was already half-open. Then I grabbed her skirt and pulled it down without hesitation.
“……Ah.”
Despite the bold action, embarrassment seemed to hit her the moment only underwear stood between us.
Lottie’s face flushed red for a moment, her lips moving silently.
She seemed about to speak, so I waited—
but all that came back was—
“……Onii-chan is.”
Lottie let out a soft laugh and shot me a suggestive glance.
“Onii-chan is…… a pervert.”
“……”
“Stripping my sister’s skirt like this—how lewd, I can’t stop it, huh……?!”
And I had no intention of listening to her nonsense. I ignored her from the middle and immediately pulled down her underwear.
Lottie struggled this time with all her strength, but the speed was different.
Because I was faster at grabbing her thighs than she was at blocking me.
“……E, ah, hah.”
Lottie’s lips trembled, then her eyes, now full of lust, looked at me.
The lewd body, completely naked, was fully exposed before me.
“W-wait, Onii-chan……!?”
She had already almost pulled off her bra. Though not huge, her small, perky breasts stood out proudly.
I didn’t hesitate for a second before reaching out—
not upward, but downward.
Tap!
“……Hah?!”
I first touched her lower belly, then slid down slowly, feeling the smooth, sensitive skin.
I played a little longer, then reached her smooth hips.
Her lewd thighs.
Finally, the very end—
“——Hug—!”
I gently pressed my fingertips against the most secret part of a woman.
Lottie’s mouth parted, and a cry of pain and pleasure escaped. I felt my whole body tingle with the sound……
“It seems even a wicked little sister like you needs a bit more profound education.”
“Haaah……!”
Clink!
I slowly unbuckled her belt.
