A Little Sister Masturbating to Her Brother Is Surprisingly Normal

The quiet dawn when most people were still deep in slumber. Just like everyone else who had finished their day and laid their weary bodies down to rest, I was lying on my bed. With the darkness as my only curtain, I had shamelessly bared my naked body.

A pathetic moan escaped my lips, disturbing the still morning air.

"Haaah… haaht♡"

Arwen, who was just as naked as I was, spoke with an oddly mischievous expression that didn't suit him at all.

Arwen had come to his little sister's room in the dead of night and was now violating me with the very thing I hated even mentioning. There wasn't the slightest hesitation on his face as he committed the sinful act of ravishing his own blood relative.

Despite his slender frame, Arwen moved his hips with violent intensity. He thrust that massive thing—the same one that had mercilessly violated Aunt Masha—deep inside me.

"Haaauuu♡ N-no, I'm not lewd at all!"

With a playful grin, Arwen pinched my clit, which was glistening with love juices from his rough thrusts.

"Hiiik?! Don't pinch my pussy♡"

The pleasure that surged from my core after that brief moment of pain shot through my entire lower body. My toes curled up tightly, except for my big toe.

Arwen didn't care about how I felt at all. He kept moving the cock buried inside me without pause.

"Haaah♡ Haaah… please, just let me rest for a moment…"

I barely managed to move my dry tongue and begged him, but Arwen's cold eyes showed no mercy.

"O-of course not… haaung♡"

Arwen, who had been focused on the way his hips pistoned into my pussy, grabbed my pitifully bouncing breasts with his hands.

What nonsense. Who was going to become whose mother?

"M-mother? There's no way I'd ever give birth to something like your baby, brother."

I tried to push Arwen away from my chest as he spouted such ridiculous things, but I couldn't budge him. He silently focused on sucking my nipple.

I could feel my nipple hardening as his hot tongue swirled around it. After sucking on it like a nursing baby, Arwen pulled his mouth away from my swollen nipple and said,

"Of course it's wrong, haauung♡ We're blood-related family, brother."

Suddenly, Arwen's face filled with a mixture of sadness and complicated emotions as he answered.

"Haaup♡ E-even so…"

Arwen gently stroked my belly as he spoke. His soft touch tickled. It tickled my skin, and the womb beneath it as well.

"There's no way…"

But Arwen remained stubborn. He held me tightly and whispered words of confession like a man proposing to the woman he loved.

At the same time, Arwen gradually increased the speed of his hips. As if he truly intended to impregnate his little sister.

"Aang♡ N-no, you can't…"

If this continued, I would really end up carrying Arwen's—my family's—my brother's baby. But I had neither the strength nor the will to push him away.

In the end.

"Haaaaang♡ I'm getting pregnant with my brother's seed—my own nephew♡"

Along with the voice of a vulgar woman accepting her brother's baby seed, Arwen ejaculated inside me. At the same time, my sopping wet pussy, which had been toyed with by the pleasure of incest, gushed out love juices. A dark stain made of warm fluids formed on the sheets beneath my ass.

The maid who would clean the bed would definitely notice the lewd act that had taken place at dawn. I wondered what she would think.

"Haa… haa…"

Hot breaths burst from my mouth like a wild horse galloping across the plains. My chest and thighs, still trembling from the aftershocks of climax, quivered in time with my breathing.

And in that moment, Arwen would have warmly embraced my sweat-soaked skin. If only the sinful, god-forbidden act of brother and sister having sex to conceive a child had been real.

The cock that had been inserted into my little sister's pussy was actually my own fingers. Pinching my clit had been my own doing. The wet tongue that had sucked on my nipple was mine as well. Even begging to give birth to a nephew—everything had come from my own filthy imagination.

Ever since I saw the obscene sex Arwen had with Masha and Raibel before he left, the number of nights I had slept soundly from evening until morning could be counted on one hand. Every time I thought of Arwen's face, my pussy would twitch.

In the end, I had reached the point where I masturbated while imagining myself rolling around with my half-brother in the most disgusting ways. Even though self-loathing and guilt always followed masturbation, I couldn't stop. The pleasure it gave me was simply too strong.

Like livestock trained by feed, my body had become conditioned to masturbating while fantasizing about having sex with Arwen.

Thanks to that, even on the dawn of the day I was supposed to depart for the Academy, I continued this dirty, lewd act while avoiding others' eyes.

"Huu… Still, I'm glad Mother gave permission so easily."

Unexpectedly, Mother had readily allowed me to participate in the academic presentation as the representative observer for the Reinhardt family. The same mother who had always hated the idea of me getting involved with Arwen.

"Hic… Sophia hasn't sent a single letter? That arrogant Arwen? Hmph. Fine, Cordelia, you go and check on them. See if they're alive or dead."

Leaving behind my worrying mother, who had been drowning herself in alcohol day and night lately, there was only one reason I wanted to go to the Academy.

"To meet Arwen and settle things once and for all."

If I met Arwen at the Academy, I would gather my courage and ask him. To stop having sex with Aunt Masha and Raibel in the mansion. To return to the days when we were just a normal family.

If that happened, surely these filthy, dirty thoughts that had been binding me like a curse would disappear ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠as well.

But… what if… just maybe…

If Arwen demanded my body the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠same way he had taken Aunt Masha, what would I do? The certainty I once had that I would naturally refuse him had already vanished.

Could my pathetic body—which had been masturbating while eagerly waiting for Arwen's hot body to press down on mine—truly reject him?

"I don't know…"

Muttering those words mixed with doubt and worry, I roughly threw on a nightgown over my naked body. As soon as I flopped down onto the bed, the nightgown clung stickily to my sweat-covered skin. The unpleasant sensation on my back made me feel like I hadn't slept at all.

In the end, I simply closed my eyes tightly, and the morning of the first day of my journey to the Academy dawned.

The atmosphere at the Academy could be described in a single word right now.

Festival.

Thanks to the visitors wandering around every corner of the Academy, the entire place was buzzing with excitement like a festival. Not only the Academy grounds, but also the city of Bremen—where outsiders would stay during the presentation period—was crowded with guests from all over wearing a wide variety of clothing.

The students were just as excited. The thrill of finally being able to show off their skills had them worked up.

Of course, the only event someone as talentless as me could participate in was the martial arts tournament that every student at the Academy had to join.

One might wonder what kind of inconsiderate event forced every student, even the weak ones, to participate in a martial tournament. But most students who didn't want to take part simply forfeited before the preliminaries even began, so it wasn't a big deal. There was no mocking or insulting those who forfeited either.

However, I was not part of that warm atmosphere.

The preliminaries were held in front of numerous professors and students watching.

"So that young man is the Arwen that Professor Helena has been praising so highly."

"It makes sense. He is from the Reinhardt family, descendants of the Sword Saint. Even the previous head, Lord Edan, used to hunt ogres like they were mere goblins."

The professors and spectators looked at me with expectant eyes. In that situation, I didn't have the courage to say, "I'll forfeit here," and kill the mood.

Well, thanks to the quest, I couldn't forfeit anyway.

The quest reward was the Charm stat—which I couldn't really feel the benefit of—and a measly 100 gold. On the other hand, the penalty was a trait with the unpleasant name [Coward].

"Damn it. If they were going to turn it into an adult game, shouldn't they have removed these sweaty combat-related quests?"

I grumbled, thinking it might make the developer's ears itch, but of course nothing changed just because I complained.

The one saving grace was the developer's truly tear-jerking consideration. The original victory condition I remembered—winning the whole thing—had been lowered to simply reaching the semifinals or better.

I easily passed the preliminaries of the martial arts tournament thanks to the power of Masha's love juices. Among the students I had trampled on my way to the main tournament was Yohan, who could now be called a bad connection.

"Begin!"

The moment Helena gave the signal, Yohan charged at me with manic eyes. From the desperate look in his eyes visible beneath his face guard, it was clear Sophia had given him some kind of order.

It was pitiful that he had become Sophia's pawn, but I had no intention of letting him win. I lightly sidestepped his reckless charge and casually stuck out my foot.

"W-whoa?!"

Yohan, who had charged without considering the weight of the armor on his chest, tripped and fell pathetically. I gently stepped on his back as he flailed helplessly under the weight of his armor and pointed my sword at his neck.

"Well? Want to keep going?"

"…Ugh. I surrender."

Yohan answered in a half-sobbing voice.

"Hmm… As expected."

Helena nodded with her arms crossed, as if she had known I would win all along. In contrast to the cheers and exclamations erupting around us, Yohan's situation felt even more miserable.

That's enough about poor Yohan. So where was I headed right now?

I was walking toward the Academy's main gate to greet Cordelia.

I didn't know what Cordelia was plotting, but she had chosen me—her half-brother—instead ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠of her real sister Sophia as the person she wanted to observe. In other words, for the next five days while the presentation was held, Cordelia would be stuck to my side like an annoying fly.

"Damn it, I have no idea why…"

In the original game scenario, both Isabel and Cordelia left the game after the prologue, so the Reinhardt representative observer seat had naturally been empty. There had been no one left in the Reinhardt mansion with a high enough position to be invited as an observer.

Therefore, Cordelia coming to see me as an observer was the root of an entirely new story that didn't exist in my memory. I had no idea where it would lead or what kind of ending it would have.

While I was walking along, lost in thought over my half-sister's sudden behavior, I soon arrived at the main gate where I had taken a carriage on the day of the entrance ceremony.

A short while later, exactly at 11:20 a.m. as notified by the Academy staff, carriages from every corner of the empire began to arrive. Among the long line of carriages, the second one from the front bore the flag with the dragon symbol of the Reinhardt family fluttering proudly.

The carriage stopped precisely in front of me, as if it had known I would be here to greet it. From the opened door, my half-sister Cordelia gracefully stepped down.

She was wearing the rather provocative dress I had seen back at the mansion, approaching me with a haughty expression on her face.
