My Little Sister's First Time Belongs to Her Big Brother
Cordelia looked up at me with trembling lips, her voice barely a whisper.
She had said it. She had begged me to take her. There wasn't a single shred of regret in my heart. Truth be told, I'd half-expected this moment ever since we stepped down from the carriage. Ever since I met Arwen—no, ever since I became her big brother—my little sister's pussy had been dripping with lewd nectar whether she wanted it to or not. Just seeing my face, just hearing my voice, made her so ashamed and twisted with forbidden desire that she'd tried acting cold or getting angry to hide it. But in the end, she couldn't escape the pull of my current.
My feelings for her had long since crossed the line of familial love. If I pushed her away, she would be the one clinging to me. Maybe this ending had been written the very first time she touched herself in the mansion while fantasizing about me. I sent a silent apology to our mother.
I'm sorry, Mother... From now on, I'm going to let big brother hold me. Please don't blame him. This is my choice.
If Mother ever found out, it wouldn't end with a simple scolding... but somehow, I felt like as long as I was with my brother, we could overcome any obstacle. It felt just like the carefree days of our childhood, when we used to run around without a single worry in the world.
With that final thought about Mother, I quietly surrendered my body to Arwen's—my big brother's—touch.
It was nothing like the romantic first times my friends my age liked to brag about, yet I wasn't nervous at all. If anything, my mind felt clearer than it had in years. Because I knew that the way my brother was exploring my most secret place would wash away the deep, aching thirst that had been building inside me for so long.
* * *
"Big brother... hold me tight."
Cordelia spread her arms with an awkward, no—more like a shy little smile. She looked just like an adorable teddy bear. I wanted to bury my face in those soft-looking breasts.
"Alright. But first, I should take my clothes off too. Can't be the only one making you feel embarrassed."
Still lying on top of her, I yanked my top off and tossed it aside. Then I sat up, faced her, and pulled my little sister into my arms with all my strength, just like she'd asked.
"Kyaa?!"
Cordelia let out a cute little scream as her massive breasts squished against my chest. The soft mounds flattened from perfect circles into warm ovals. We stayed like that for a while, silently savoring each other's warmth. Every time she breathed out, her chest would swell and press even tighter against me, then shrink again. Our nipples kept brushing together, and each time she let out a tiny moan.
"Haaah♡"
After about five minutes of warming each other with our body heat, the embrace ended. It had been our way of confirming our resolve before the real act began. Cordelia pulled back slightly and ran her hands from my thighs up to my waist.
"Hehe, your body's gotten so much better than when you were at the mansion, hasn't it?"
I saw myself in the mirror every morning, so I hadn't really noticed the change. But to Cordelia, who hadn't seen me in so long, it must have been striking. After all, my current strength stat was 26—more than five times what it had been when I first possessed this body. It would have been strange if there wasn't any difference.
"I've been training hard at the Academy. Why, does it feel weird?"
Cordelia didn't deny it.
"Well... the only version of you I've ever known was skinny and frail."
Even as she said that, she wrapped her arms around my neck. My nose and mouth sank deep into the soft valley of her breasts. A sweet, milky scent rose from her cleavage—like baby formula, but somehow intoxicating. In that position, she continued.
"Still... I don't hate it. If anything, it makes me want to lean on you more?"
When I lifted my head a little, I saw her face flushed with shy embarrassment. I wasn't sure if she meant leaning on me as family or as a lover. Maybe both. Either way, it didn't matter.
"Don't worry. From now on, I'll let you lean on me as much as you want."
I shifted my weight forward. The two of us tumbled onto the bed, still tightly embraced. Cordelia now lay on the soft sheets that had wrapped around my body every night. She was here to mix her body with mine.
"Th-this is my first time, so..."
Cordelia covered her eyes with one hand, clearly embarrassed.
"Please, big brother... be gentle with me..."
Those words—entrusting her one and only first time to me—stirred both my lust as a man and my primal urge to conquer. I almost wished I hadn't heard them. From that moment on, I couldn't see Cordelia as just my little sister anymore. A fierce impulse surged through me, demanding that I thrust myself into the woman lying before me right this second.
"...I'll try my best."
I answered with the kind of reply that left room for failure instead of a confident "I will." Even that much was only possible because I was barely clinging to my sanity. While the desire to make my little sister pant and moan burned inside me, I brought my lips to hers.
This time, unlike during our first kiss, Cordelia didn't push me away. Her lips were still trembling, though. As I eagerly sucked on her tongue, my right hand began to knead her thigh—firm yet gentle, like working out a knot in a muscle. My hand slowly, very slowly, traveled upward from her thigh toward her groin.
"Haaah? Th-that place..."
"Don't worry. Just leave it to me."
Instead of answering, Cordelia squeezed her eyes shut. I didn't need to ask what that meant. The moment my finger touched her pussy—which had already lost its underwear long ago—her tongue twitched hard. I gently stroked her soft folds. They were hotter than my fingers and slick like the inside of a mouth. Her cunt was already soaked with love juices, more than enough lubrication for penetration, but I still wanted to caress her properly. I didn't want to miss my little sister's adorable reactions when her big brother's fingers entered her.
I slowly pushed my middle finger inside her hole. A moan immediately slipped from Cordelia's previously sealed lips.
"Huuuuh♡ Haa... haa..."
The tip of my finger felt warm. It was like dipping my hand into a cup of hot water. Her twitching hole sucked on my finger like a baby nursing at a nipple. When I curled the tip and scraped her inner walls, Cordelia's whole body jerked slightly. I didn't stop there. I pinched her clit between my index finger and thumb. She twitched even harder than before.
Cordelia pulled her lips away for a moment and gasped.
"B-big brother, I feel so strange... please be a little gentler..."
"It's because you're not used to a man's hands yet. Try to relax your body."
"...Okay. I'll leave it to you, big brother."
After that, Cordelia completely surrendered herself to my rhythm. The wet, slurping sounds of our tongues intertwining filled the air as saliva dripped down. It was so much that I started to worry we might actually get dehydrated. The frequency of her pussy twitching as I attacked both her clit and her hole at the same time kept increasing. She was clearly about to cum soon.
"Phew... Cordelia, are you about to cum?"
With glazed eyes even hazier than before, she nodded.
"Y-yes... my lower belly is tingling so much because of your fingers♡"
"Good. Then don't hold back. Just let it go."
"Haaauuuuh♡ C-cumming♡"
Cordelia climaxed with my fingers still buried inside her. At the same time, a gush of her juices sprayed out around them.
"Haa... haa... it felt twice as good as when I do it alone... why?"
She spoke with a genuinely puzzled expression. I smiled softly.
"Maybe it's because you're doing it with someone you love?"
"L-l-l-love..."
Cordelia stuttered like a broken radio at the direct word, then suddenly looked straight into my eyes.
"That's right. I love you, big brother... What about you? Do you love Cordelia too?"
She bit her lip tightly, her face tense with nervousness. I gently stroked her cheek.
"I love you. Both as family and as a woman."
At that, Cordelia broke into a bright, bashful smile.
"So it wasn't just me who liked you... I'm so glad... Then..."
She slowly spread her legs. The tiny hole I'd just been fingering twitched and glistened openly.
"Put your cock inside your beloved little sister. If you run away now, I'll never forgive you for the rest of my life."
As if I could run away. Not when the woman who loved me was lying here, waiting only for me. Even if that woman was my little sister.
Instead of answering, I slowly undid my belt. When I pulled my pants down, my cock sprang up at its fullest, hardest angle. I gathered my courage and positioned myself over my little sister, who had bravely taken such a shameful pose in front of her big brother. Her plump thighs overlapped with mine. The tip of my glans kept nudging against her groin. My cock was waiting only for the command to penetrate.
"I'm going to put it in now. It might hurt at first, but don't be too tense. I'll be as gentle as I can."
Cordelia nodded. I carefully aligned my glans with her entrance. Her twitching pussy swallowed the head. Then, very slowly, I pushed my hips forward and slid the tip inside her.
"Haaah?"
"Does it hurt? Should I stop for a moment?"
"N-no... keep going..."
Looking into her determined eyes, I continued pushing the rest of my length inside her. When my cock was finally buried to the hilt, Cordelia let out the moan she'd been holding back.
"Huuuh, ngh, haaaahng♡ It's inside! Big brother's cock is...!"
She looked like she was already on the verge of climax just from being penetrated. Cordelia stared down at her own pussy, now filled with a man for the first time, then shyly covered her face. Her chest heaved as she panted out hot breaths of pleasure.
Of course, she wasn't the only one lost in ecstasy. Even though I wasn't moving my hips yet, the folds of her pussy clung stickily to every inch of my shaft. If I didn't clench my lower abs, I felt like I would cum immediately.
"I-I'm going to move now, Cordelia. Is that okay?"
"Haaang, y-yesh...♡"
Her pronunciation was completely slurred. I wasn't sure if she was really okay or not. Suppressing the urge to cum, I began to move my hips slowly. Every time I pulled out and pushed back in, the way her inner walls caught on the ridge of my glans made my mind go blank. I'd had sex dozens of times since possessing this body, but the pleasure Cordelia's pussy gave me rivaled the feeling I'd had when I lost my virginity.
"Kgh, it feels so good... Cordelia."
"Haaang, haaang♡ G-good... I like having sex with you too, big brother♡"
Cordelia reached out to me.
"Hold my hands. I want to hold big brother's hands♡"
I interlaced our fingers. Like lovers. She might be my sister, but since I loved her, it didn't matter. The moment our hands touched, she squeezed them tightly, as if she never wanted to let go.
"Haaang♡ We're one now. It's even better than I imagined♡"
Still holding both her hands, I pressed them down onto the bed. Then, overlapping with her body like a sandwich, I began thrusting my hips. Every time I moved, her breasts brushed against my chest. Her cute, softly rounded belly did the same. Her thick thighs slapped rhythmically against mine with wet smacks.
"I feel like my cock is going to melt. You're the best, Cordelia."
"Haaaaang♡ Me too! My insides are so hot because of your cock! I think I'm going crazy♡"
Squelch. Squelch. Squelch. The obscene, wet sounds of our incestuous sex rang out loudly, but I didn't care. I'd long since forgotten that we were in a dormitory.
"To think that siblings who share the same blood have such perfect compatibility... Mother would faint if she knew."
"Haaang♡ Don't talk about Mother right now, it's so embarrassing♡"
Cordelia pouted her lips cutely. The sight was so adorable. And of course, being told not to do something only made a man want to do it more.
"Why? We'll get caught eventually anyway."
"G-get caught? Haaang♡ If we just stay careful..."
I didn't stop moving my hips as I whispered into her ear.
"You really think so? What if you get pregnant with my baby and your belly starts to swell... and what if the baby's hair is silver? Don't you think Mother would notice then?"
"P-pregnant? No matter what, there are lines that even we shouldn't cross..."
The moment I said the word "pregnant," her pussy clenched tightly around my cock. She had definitely imagined a future where she gave birth to my child. Besides, the moment siblings started having sex, that line had already been erased. We could just draw a new one.
"I want to get you pregnant, Cordelia. I don't care if it's a boy or a girl."
"Haaauh... even if you say that..."
I kissed her hesitant lips. When I pulled away, I said firmly.
"I'll keep going until you give me permission."
"Th-that's not fair... mmmph?"
I kissed her again, then pulled back.
"Still no?"
"..."
This time she stayed silent. Just as I was about to kiss her wordless lips again, Cordelia finally spoke.
"...I understand."
"What?"
"I'll do as you say... haaah..."
Cordelia, who had just given permission for an incestuous pregnancy, squeezed her eyes shut and murmured.
"I'm sorry, Mother, Father... haaang♡ I'm going to become big brother's baby mama."
It was like a nun confessing her sins to God after committing an act of lust. Cordelia was begging forgiveness from her family in front of the sinful seed that would be born from our incest. It was a single sentence packed with the ultimate taboo that normal families would never feel or experience. How the hell was I supposed to hold back after hearing that?
My cock, wrapped in the tight embrace of her vaginal walls, throbbed violently. A burning sensation rose from my lower belly. I had reached my limit.
"I'm going to cum inside you, Cordelia. I'm going to fill my cute little sister's womb. Ngh!"
Cordelia wrapped her arms around my neck and her legs around my back. Her sweat-slicked skin stuck to mine. Even the sharp scent of our mingled sweat felt good. In that position, she cried out.
"Cum! Fill Cordelia's baby room with lots and lots of big brother's semen♡"
I released the ejaculation I'd been holding back. Hot semen burst through my urethra. The sheer depravity of pouring my seed into my little sister's womb made my entire cock pulse with pleasure. As if determined to empty every last drop in one go, this became the longest ejaculation I'd had in a long time.
"Haaang, haaang♡ My belly is full of our future nieces and nephews♡"
Cordelia clung tightly to me as she spoke. I could feel her whole body trembling cutely from the lingering waves of climax caused by her big brother's creampie.
