Playing Hard to Get with My Obsessive Sister
“……Wait just a moment. Lottie.”
“I won’t let you escape.”
“No, that’s not what I meant…….”
Was she worried I might slip away from her entirely?
Lottie had sharpened her nails on both hands in a futile attempt to restrain me, her small frame radiating that delicate threat of violence she was all too ready to unleash.
“I’m only asking for a few minutes, Charlotte.”
“…….”
By speaking in a calm, serious tone, I made her pause, her narrowed eyes glancing up at me.
And her gaze, as if piercing straight through my intentions.
“……Is the big brother trying to put on some boring play just to kill time…….”
“I told you, no.”
“……Huh, ah.”
I suddenly sat up. The motion startled Lottie so sharply that her eyes widened in surprise.
She swallowed hard, her pupils dilating as she stared up at me, her cheeks flushing a deep pink.
I supported her chin with my hand, brushing past her flushed jawline as I continued in a soft voice.
“I clearly said that isn’t the case.”
“……O-older brother, this, if you touch it like that, it’s ticklish, yah.”
“I have no intention of avoiding it, so just wait obediently.”
“E-err……?”
“You say you love me, yet you won’t even do this much?”
Love. The word Lottie cherished above all others.
I placed extra emphasis on it, gazing down at her with a calm, lowered gaze, and she trembled subtly yet visibly excited, her body quivering in response.
“A-anyway…… I, I don’t doubt you, older brother, I’m just, um…… maybe, so…….”
As expected, the effect was overwhelming. Lottie’s face flushed from the crown of her head, her body twitching as if sparks were flying off her skin while she fidgeted with her hands.
“Haa.”
At that moment, I deliberately let out a low sigh, hoping it would quiet her racing thoughts.
“I won’t say it twice, Lottie.”
“…….”
“Get dressed, change into something appropriate, and go to the room below—your bedroom. Don’t do anything, just wait there obediently.”
“……Yes, ah.”
Steam practically poured from her head. It might have been my imagination, but she nodded in perfect sync.
I smiled with satisfaction and gently stroked the silky strands of her light-blue hair.
“Good girl, our little sister.”
“……Ek, um, ah.”
And Lottie immediately erupted. Her head shook with a mechanical, jerky motion, almost like a malfunctioning toy, her expression comically displeased.
I brushed a strand of her bangs aside and lightly kissed her lips.
“……!!”
A startled reaction surged from below, but I ignored it and stood up, leaving the living room.
Glancing back at the end, Lottie was blankly staring at her own forehead, wide-eyed.
Perhaps because she hadn’t received the affection I had initiated earlier? She looked even more flushed than before, the sight of her smoking ears almost unbearably cute.
“……Huu.”
I climbed the central staircase to the upper floor, tidying my disheveled tie.
I had noticed too late, but it seemed she had grabbed my throat when she first climbed onto me.
‘My troublesome little sister…….’
It had been a brief moment of respite, yet I already felt ten years older.
How could someone like me—her beloved older brother—receive such cheeky behavior?
If I could, I would grab her right then and there and discipline her, but what good would it do without her here?
Anyway, I would just keep crumbling emotionally the moment I saw her smile again.
……I had already crossed the line of no return for physical intimacy. The window for fixing it had long since closed, and so…… there was no solution.
Creak—.
So my conclusion was that even a second-best option, however temporary, had to be prepared.
Entering the dimly lit study with not a single ray of light, I walked straight to the desk.
Since I had reinforced my night vision with mana, I didn’t need to wait for my eyes to adjust. With a loud clunk, I pulled open the second drawer from the top.
“…….”
With a complicated expression, I picked up one item.
A small, square-wrapped package that could easily fit in the palm of my hand.
In this world, even in this era, contraceptives existed. Obviously.
And strangely enough, this…… the ‘condom’ made from magical synthesis material matched the quality of modern ones in every way.
When I first discovered it a few days ago, I was a little surprised, but it wasn’t actually that strange.
‘Even if science is still a bit crude, the world has magic, after all.’
Of course I could create high-quality contraceptives if I wanted to.
Thanks to that, I was definitely benefiting.
I looked down at the floor of the study with an unprecedentedly solemn expression. There was some error, but it was almost directly beneath my bedroom…….
“Huu. Calm down, calm down.”
I took a deep breath to steady my churning insides. Think simply, Isaac Havertz.
‘It’s inevitable anyway.’
Although I wouldn’t call it a curse in front of my sister, I decided to forgive myself for now.
I couldn’t avoid Lottie. I couldn’t ignore her. I couldn’t negotiate or compromise.
From the start, my psychology didn’t reject her at all. If Lottie set her mind to it, I couldn’t endure it.
As I said earlier, that’s why I needed a backup plan. This stack of condoms in my hand was my solution for now.
I didn’t know how long this dangerous relationship—neither full siblings nor lovers—could last.
But at least—until we had a serious conversation and reached a conclusion, if I wasn’t ready to reject her requests for physical intimacy, I couldn’t leave her unprepared for the responsibilities.
And that ‘responsibility’ was, without question, pregnancy. Carrying a child.
I clenched my fist, gripping the condom tightly, and turned my body decisively.
It was time to head to the battlefield…….
*****
“What? No.”
“…….”
And I was rejected in less than a second.
So what exactly was rejected?
Sexual intercourse with the condom.
I instinctively felt dizzy and wanted to press my forehead, but I endured it with superhuman patience while looking down at Lottie.
She had been waiting obediently inside the bedroom, exactly as I had said. Her expression was shy, her face flushed, and her eyes expectant.
She was sitting in perfect posture, both fists resting on her knees.
It was such a cute sight that I wanted to bite it, but that fantasy was shattered the moment I offered her the condom.
Her face crumpled instantly.
I pressed my temples to suppress the headache and began to persuade her calmly.
“Lottie, don’t. You know why this is necessary, right? If we’re going to have sex, we have to use protection——”
“I want your baby, older brother.”
“…….”
And again, a one-second kill. I coughed awkwardly at her sudden bomb of a line interrupting me.
……I didn’t even know what I had just heard. This, what, no, I did hear it, but it felt like my mind was about to break.
I sent her a serious gaze, but she seemed unwilling to retract the explosive statement.
“If you didn’t hear properly…… I’ll say it again. Older brother.”
“……No, I heard you clearly.”
“Can’t be helped. Hmph, hmm. Listen well?”
She stroked her lower abdomen with a seductive hand as if to emphasize it even more.
She was not listening to a word I said, her sparkling eyes gleaming with mischief.
“……Aah, older brother.”
And she pouted her small lips while performing a perfectly staged tantrum.
She brought both fists near her pale cheeks and gave them a light flick.
She was about to say something to make me even more dazed without hesitation.
“Lottie, can’t you get pregnant for me?”
“…….”
X.
The curse word I rarely used even after transmigrating had automatically risen to my throat.
Fortunately, I didn’t say it, but it didn’t improve the situation. A moment ago, I had nearly lost my mind over even a tiny bit of damage.
And tonight, without even a proper break, I had…… devoured her insides like an animal.
And the moment she got pregnant with my child, we would have gotten married?
Ah, the image of walking down the aisle with Lottie surrounded by the blessings of vassals and nobles was already burned into my mind.
Pregnancy wouldn’t be so simple, but the future was still chillingly terrifying.
I shuddered when I realized it and finally regained full control of my reason.
I looked down at Lottie with furrowed brows and shook my head with a sigh.
“That’s not happening, Lottie.”
“……Eh, why!!”
And without a moment’s hesitation, Lottie screamed at the top of her lungs. She slammed her body onto the bed, her cheeks puffing up dramatically.
“I don’t want it! It, it won’t feel right……!”
“……Wait, w-what?”
“Isn’t it already weird to have a wall of condoms between siblings?!”
“……Ah, ha. Lottie. You shouldn’t use such vulgar language. I’m asking you nicely.”
“What’s wrong with what I said!!?”
She shot up, looking ready to slap me. Lottie began stripping her clothes one after another with fierce determination.
“Enough, enough. I don’t need that, I want the real thing! No room for negotiation, no room for compromise!”
“You really are shameless…….”
“Shameless or not, it’s disgusting, and you can’t even touch me anyway?”
Charlotte stood tall with her completely naked body, spine straight.
She confidently pointed out my weakness, striking exactly at the part I had been worrying about deeply.
……Even if Lottie came out shamelessly, I probably wouldn’t feel that bad, and I wouldn’t raise a hand to her anyway.
“……This won’t do either.”
“What?”
I didn’t intend to let her get away with it.
Letting out a sigh, I grabbed my tie.
“Lottie, how about this instead.”
“……Eh? What?”
“If neither of us is willing to back down, then we’ll have to settle the hierarchy, won’t we?”
“Hi-er……?”
Lottie blinked blankly at my meaningful words, and I immediately climbed onto the bed, crossing my knees. Somewhat roughly.
‘Jolting!’ Lottie gulped down her saliva and looked up at me as naturally as possible.
“Our little sister loves this kind of lewd stuff…… I might have to accommodate that part for you.”
“Eh……?”
“Let’s make a simple game. Something that unifies us when our opinions differ.”
I leaned closer to Lottie, my upper body lowered, my eyes flashing sharply.
“I’ll give you exactly what you wanted. Go ahead and grab me and make me satisfy you.”
“……Nehet?”
“In return, I’ll fuck the inside of your thighs like crazy.”
Lottie smiled awkwardly but looked at me with trembling eyes. And I finished with my index and middle fingers gently spread.
“The one who gives up first loses. The one who makes the other give up first wins.”
“──Ah.”
“How’s that? The rules are super simple, aren’t they?”
I smiled gently.
Lottie’s red eyes held a mixture of a tiny bit of pride and rigid tension.
