The Fallen Sister's Womb

Just before I climaxed in Sophia's embrace, I clenched the muscles in my lower abdomen and paused our sex for a moment. Continuing with the monotonous hip movements until ejaculation felt somehow lacking. With the walls in Sophia's heart regarding incest now torn down, this was the perfect opportunity to teach her just how immense the pleasure of taboo could be.

When the older brother who had been mounting her suddenly stopped moving, my younger sister looked at me with a strange expression. Within Sophia's bewildered face, I could detect a slight hint of disappointment.

Sophia tapped my shoulder as if trying to wake a malfunctioning appliance and asked, "What's the matter? It can't be that you suddenly got scared right before cumming inside your little sister. That kind of pathetic reason, right?"

With the hand that had been tapping my shoulder, Sophia caressed my neck. "Since you've forced those embarrassing words out of my mouth, I won't permit you to run away. Oppa♡ Now that we've come this far, we're heading to the end no matter what anyone says. Together with me."

Sophia's cold touch circled my neck like a menacing winter wind. Contrary to her gentle voice, the atmosphere was extremely sharp. In Sophia's eyes as she suggested going to the end together, I could even feel a hint of frenzy.

After all, if the person who had convinced herself with absurd logic like family affection through breastfeeding were to get scared and flee at the last moment, from Sophia's standpoint, there could be no greater humiliation. No, it would be a betrayal rather than humiliation.

But this time, Sophia had jumped to the wrong conclusion. What man would run away with such an alluring woman's naked body right before his eyes?

"Don't worry. It's definitely not for that reason."

After reassuring Sophia, I whispered my request into her ear. In an instant, Sophia's cold demeanor melted away. She withdrew her hand from my neck, then rose from the bed, adjusting her posture before speaking.

"I don't know what kind of position you're making your younger sister take right now. Do you perhaps see me as nothing more than your personal whore? You lewd pervert of an older brother♡"

Sophia denounced her older brother with words dripping with obscenity. However, it wasn't laden with the kind of malice that would be directed at a repulsive bug like before. How could I tell? For starters, her voice was full of mischief. The tone was remarkably similar to what Cordelia often used when being intimate with her older brother. Sisters really are sisters, I suppose.

Besides, in front of the person she called her pervert older brother, she was swaying her hips seductively as if she were a dancer in a brothel. And she was doing so while on all fours on a bed where the sheets were ruined with stains of dried love juice and semen.

Sophia's love juices flowed down her sturdy thighs that remained unshaken even on the creaky cheap bed. Beads of sweat glistened on her spine, which possessed seductive curves like silk thread.

Instead of answering Sophia's denouncement, I massaged her flawlessly white ass with my hands. My fingers sank into the mass of flesh that boasted a dough-like elasticity. It was so soft that closing my eyes might make me mistake it for fondling breasts.

Savoring her thick pelvis that contrasted with her slim waist both visually and through touch, I said, "Who's the one wiggling her ass because she wants to get pounded by her lewd older brother?"

"Wi-wiggling?"

Despite Sophia's dumbfounded voice, I adjusted the position to make rear entry easier. Her sweat-drenched, sticky thighs clung firmly to my own thigh flesh.

"I'll put it in now."

The stiffness of my member was holding up well, nourished by the sight of Sophia's captivating backside. Sophia's female opening was also fully prepared to receive a man's organ without needing separate caresses.

I aligned my cock with her hole and, unlike before when I had adjusted the insertion speed, I pushed the entire shaft in at once. Simply changing the angle of penetration subtly altered the sensation of her vaginal wrinkles entangling around me.

"Haaaaang♡ Hic♡"

Simultaneous with the insertion, I noticed Sophia's toes curling up. Even though this wasn't the first insertion, Sophia's vaginal walls spasmed merely from her older brother's cock entering. Thanks to my younger sister's vaginal folds squeezing violently like they were handcuffs, my cock was trapped helplessly like a captured prisoner. The grip was so tight that I wondered if the imprints of her folds would be left on my shaft when I pulled out.

Unlike the gentle first experience, Sophia—who was tasting the intensity of doggy style, a position meant solely for pleasure, for the first time—expressed her sensations in cries close to screams.

"Haaung♡ It's completely different stimulation from before; it's scraping all kinds of new spots so intensely♡"

From the hand gripping her ass, I could feel the tremors that came when a woman climaxed. The same from where our thigh flesh was stuck together.

In truth, if she wanted, she could stop this shameful position resembling a bitch in heat at any time. But even while her arms and legs were trembling, Sophia was striving to maintain this posture. Whether it was to keep her promise with me or simply because she desired the pleasure, I wasn't sure. But watching my commendable younger sister, a passion burned deep within my heart. The passion to make the copulation for Sophia's first pregnancy in her life into a definitely happy memory.

"I'm going to move now, Sophia. I'll definitely satisfy you with my cock all the way to the deepest places that other men can never reach."

Using Sophia's pelvis as a grip, I steadied my position and thrust my waist toward her with my body weight. Sophia's soft ass and thigh flesh that were in contact compressed and adhered closely to my body.

"It's all the way in♡ To the deep place that Arwen oppa talked about!"

Sophia moaned, seemingly without much psychological resistance anymore to calling me Arwen oppa. The glans that had penetrated her deepest part was buried in vaginal walls resembling a towel soaked in hot water. The strength of Sophia's female hole grew increasingly powerful. Like a female praying mantis devouring a male, it seemed poised to consume the cock that had entered her. It was an S-laden pussy that took after its owner's rough personality perfectly.

Damn it, snap out of it, Byeon Tae-sung. Show the dignity of the protagonist.

To avoid being defeated by Sophia's constriction that even converted the pain of my cock being crushed into pleasure, I had to concentrate all my mind on my lower abdomen. I must have unconsciously put too much strength in my fingers, as Sophia's ass flesh caved in deeply. But perhaps because the immense pleasure surpassed any pain, Sophia didn't seem to feel any discomfort from merely having her ass grabbed.

I pulled back the waist I had pushed in. My cock, which had been lodged inside her vaginal walls, broke free from the clinging folds that seemed to beg it not to leave and moved toward the outside of the hole. Then, when about half the base of my cock had come out, I thrust my hips forward again. Thus began the intense reciprocating motion.

Squelch, squelch, squelch. Wet, sloppy sounds that made the bed's creaking seem insignificant filled the room.

As if drawn by the noise, I sensed Cordelia and Emilia approaching us as we mixed our bodies violently. I could hear Cordelia muttering something, but it only tickled my ears without being comprehensible. My apologies, but I had no attention to spare for them. Suppressing the explosive urge to cum from my cock was all I could manage.

Sophia was no different in being indifferent to Cordelia and Emilia. The image of Sophia who disliked showing sexual disarray in front of others because she wasn't a lewd whore had vanished long ago. The Sophia prostrated before me was merely a female dog in heat. Since she was already engaging in intercourse with blood-related family, what did it matter what was on display?

Sophia was descending the steps of common sense one by one, guided by pleasure.

"Haaauung, it feels good, oppa♡"

"How about it? Calling me oppa feels much better, doesn't it?"

"Oppa♡ Oppaaaa♡ My insides are getting destroyed by Arwen oppa's cock!"

With the word "oppa" now fully attached to her lips, Sophia rocked her hips in sync with my movements. Every time her pussy hole was churned by the thick rod, her entire pelvis twitched. Thanks to that, Sophia's clean anus was clearly visible. I wanted to touch the other hole that twitched as if tempting me, but my hands wouldn't obey. My mind was in a daze.

Like a doll capable of only one motion, I shook my hips mindlessly, intoxicated by pleasure. The moment the ejaculation sensation exploded arrived quickly. The throbbing in my lower abdomen told me that enduring any further was impossible.

"Kuh... Sorry, Sophia. I don't think I can hold back any longer."

The heavily sweating Sophia answered in a voice hoarse from heavy breathing.

"Haah, what does that mean? That you're about to cum? Hic♡"

"Yes, I'm going to ejaculate inside you, Sophia. Inside my little sister. Is that alright?"

The meaning of "alright" wasn't simply seeking permission for internal ejaculation. It was ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the final permission asking if my seed could settle inside Sophia's womb.

The perceptive Sophia accurately caught the hidden meaning in my words. Still in her prone ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠position, Sophia nodded her head.

"It's alright♡ I'm ready. Before I change my mind, put in oppa's baby seed♡"

"Good. I'll definitely get you pregnant, Sophia."

Responding to Sophia's determination, I pushed my hips forward, feeling the glans press firmly against her womb entrance. In that state, when I released the pent-up ejaculation urge, my cock felt the sensation of the urethra being sucked as it spurted out sticky fluid.

Simultaneous with her older brother's semen filling her womb, Sophia climaxed. As if all the climaxes until now had been mere tremors before a major earthquake, an incredible convulsion engulfed Sophia's entire body.

"Haaang♡ Haaaaang♡ My womb is so hot♡"

Sophia shouted her simple yet precise impression of the vaginal ejaculation and collapsed onto the bed. In fact, it was admirable that she had endured this long.

After withdrawing my cock, I stroked the head of the utterly spent Sophia, who had even stuck out her tongue.

"You worked hard, Sophia. It was the best."

While I was gazing at Sophia, whose belly had swollen full with her older brother's semen, a notification window appeared between Sophia and me. It was an alert announcing the successful completion of the quest.

That meant a new life had taken root inside Sophia's womb.

The fate of Short-lived had been avoided, but now in one year I would become the father of two children. And by borrowing the wombs of two younger sisters at that. If twins came out, it might be more than two.

Just listing the words—child, father, younger sister, womb—made my mind feel somewhat dizzy. Still, what use was there in getting scared at this point? The dice had already been rolled.

Status window!

I inwardly summoned the status window to confirm the quest's reward. The reward was a trait with the peculiar name Family Love, just as the quest window had predicted. And its effects were as peculiar as its name.

Because it was the reward for a pregnancy-related quest, the Family Love trait had effects related to children.

Elysia Story did have a birth system. Of course, there ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠were no cutscenes whatsoever—from getting pregnant to giving birth, everything was summarized in a single line of text.

To explain the birth system simply, it existed to carry traits and skills over to the next round. For example, rather than carrying over every trait and skill obtained from quests or dungeons in the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠first round to the second round, when children were born from the heroines, only the traits and skills inherited by the one child the player selected could be taken to the next round.

In other words, it wasn't a particularly necessary effect for me right now. After all, I had no idea whether dying—game over—in this world would trigger my first regression, send me to the afterlife, or return me to my original world.

What mattered was the effect written on the very bottom line. Roughly interpreting its meaning, it seemed to be an effect that prevented others from condemning you even if you shared forbidden love with family.

I wasn't sure how far the criteria for "special relationship" and "those around you" extended, but that was something I could find out through direct experimentation.

"...Does this mean my reunion with Isabel back at the mansion is going to be even more interesting?"

Already, wicked ideas on how to toy with Isabel were bubbling up wildly in my head.
