Chapter 205: Siriel (4)

“I’ll take care of everything, just enjoy it, brother.”

Although Siriel spoke confidently, nothing happened immediately after she said it.

Siriel’s hand, which was holding the penis, trembled slightly. When she thought about actually putting it in, she became nervous.

Gulp.

She tapped the penis lightly, measuring it with her hand. She hesitated, wondering if it would go in smoothly since it couldn’t be fully wrapped around with her hand.

Before even inserting his penis into her, her vagina was already dripping and wet with anticipation. However, Siriel was unsure if her inexperienced vagina could safely accept it.

That’s because,

Siriel had preserved her virginity solely for her brother, refraining from any lewd acts like rubbing, fearing it might wear out. Naturally, her vagina was well-lubricated and warm, but the hidden entrance inside was bound to be tight.

Could it really accept it properly?

Various hesitations arose. Since it was her first time, Siriel’s heart wavered. She wasn’t afraid of the pain of inserting his thick penis, but she was scared of appearing weak for screaming just from losing her virginity.

“…Hoo.”

In that moment of hesitation, Shiron let out the breath he had been holding. His face was stiff, even visible in the darkness, and he exhaled heavily onto Siriel’s face.

Gulp… Siriel swallowed the saliva that had gathered in her mouth.

The breath brushing against her nose was sweet. The glans pressed against her lower lip, eagerly wanting to enter her vagina. His face looked even more handsome today. The brother she loved was desiring the next step.

‘…Sex with brother is supposed to be painless and pleasurable.’

Siriel took a deep breath and steadied herself. She almost lost her focus at the crucial moment.

Resolving her mind, Siriel circled the glans around her vagina… then slowly relaxed her legs.

Slowly, deliberately…

Creak-

The penis slid between her warm, moist lips.

Squish—

Her heated vagina completely enveloped the penis. Despite feeling resistance halfway, Siriel, drooling slightly, lowered her hips.

“…Hnnng♡”

The lewd moan that escaped was far more stimulating than the imagined embarrassing scream she had feared. The first lewd sound she ever made was much more arousing than she had expected.

A sharp pain climbed her spine, but the overwhelming sense of fulfillment tingled her lower abdomen. The reward of giving her virginity to her beloved, the intimacy of flesh against flesh, was incomparable to anything else.

Shiron felt the same pleasure.

Having rubbed against stockings for a while, his penis was slightly sore and heated. The previous pricking sensation when his penis was lightly tapped disappeared when it was thrust into her hot, heated vagina, replaced by an indescribable pleasure that surged from the penis.

Like a mother’s gentle touch soothing a wound, the new sensation was as if a healing ointment was applied to the penis. The unprecedented stimulation naturally brought intense pleasure to the point where his lower abdomen tingled.

Being attacked in the dark,

Moreover, seeing his younger sister, who he had lived with for so long, filling his vision with such an obscene appearance.

Siriel’s figure, now mature and filled out, her once flat chest grown large enough to not fit in one hand, was shocking.

Lewd.

Siriel, trembling and unable to move after inserting the penis, was lewd. Her melting, collapsing face was lewd.

The swaying breasts after she had thrown off her underwear were lewd.

Her vagina, gulping his penis and trembling, was also lewd.

With the engagement already established, Shiron didn’t care about anything else. What did it matter if the situation was coercive?

Shiron decided to think that it was just that the sex, which would have happened after the proposal, was simply brought forward.

“O-Brother, how is it?”

Pant- Pant-

“My vagina… does it feel good?”

Siriel spoke with a crumbling expression, unable to control her face due to the tingling in her lower abdomen.

“I’ll make it feel even better. Just wait a moment…♡”

Due to the overwhelming pleasure, Siriel couldn’t control her body properly. Losing her virginity? The pain of penetration? Her vagina barely stung. The greater cause was the tingling pleasure that muddled her mind, but Shiron, watching from below, was thinking something entirely different.

“If it hurts, we can take a break.”

Shiron thought Siriel was pausing due to the pain of losing her virginity. Considering that even the demon Yuma had a hard time accepting his large penis, he couldn’t believe that the inexperienced and naturally weak Siriel could accept it without trouble.

Shiron stroked Siriel’s face.

“Don’t overdo it.”

“I’m fine… I can do it.”

Mumbling, Siriel lifted her hips with a squelching sound.

“Hnng♡”

Squelch-

“Ahh♡!”

What a commendable service spirit. Siriel, as if she could endure any pain of penetration for the sake of her beloved, began to move her hips with heated moans.

Shiron, lying beneath her, had mixed emotions.

Resentment.

Admirability.

Conflicting feelings clashed.

He had reserved the top floor of the most expensive hotel in Rien for Siriel’s first experience, but now the location was an unknown, stuffy room with no ambiance.

But wasn’t everything ultimately for Siriel’s happiness?

As long as Siriel was happy, wasn’t that all that mattered?

Many thoughts crossed his mind, and now the proposal didn’t matter anymore.

Judging by the lingering metallic scent in his nose, Siriel must not have masturbated or inserted anything inside before this. It was naturally painful and stinging.

Shiron felt deeply sorry for Siriel. How desperate must she have been to endure the pain of losing her virginity and move her hips?

Though it must be painful,

Siriel was tightening her vagina desperately, mimicking a seasoned mistress. Even while biting her lower lip to endure the pain, she didn’t stop moving her hips.

Of course, Siriel was actually biting her lip to avoid losing herself in the immense pleasure, but even Shiron couldn’t notice such subtle facial expressions in the dark.

It might have been the culmination of emotions that had built up for a long time that led to the current situation. Shiron felt deeply sorry for Siriel.

“Siriel…”

Shiron’s guilt grew as much as the pleasure he felt in his groin.

He repeatedly reminded himself that the proposal he had carefully prepared for years was ultimately to make Siriel happy.

With growing guilt and pleasure, Shiron gently grasped Siriel’s bouncing chest.

“Siriel is an adult…”

“Yes, I am. I’m an adult♡”

Siriel placed her hand over Shiron’s hand on her chest. While she enjoyed his hesitant, tender touch, she wished her beloved brother would desire her body more aggressively.

“You can grab harder, I’m sturdy. I’m an adult…♡”

“…”

“It’s okay…!”

As Shiron hesitated, Siriel, anxious, grabbed her chest with his hand.

Shiron kneaded her soft chest with his covered hand. It was a gentle touch. The hardening nipples brushed against his palm, and every time it sent shivers of pleasure through Siriel.

“Harder! Do whatever you want, brother!”

Siriel shouted, her expression unruly, unable to hold back her words any longer. She hoped Shiron would understand that all her sudden actions stemmed from love, despite her inability to hold back after hearing his words of love.

Even so, Siriel didn’t stop moving her hips. She tensed her elastic thighs, tightening and loosening her vagina around the penis, as if urging it to ejaculate quickly.

Squish squish.

Slosh slosh.

Each time, his penis pounded her lower abdomen, making her head throb. But it wasn’t unpleasant; it was utterly blissful.

“Because I love you… it’s okay for me to do what I want too, right?”

Emotions that had been suppressed for years. The frustration of not being able to approach him actively because she worried it would burden him. Siriel squeezed Shiron’s hand tighter as she let out more of her true feelings.

“Hnn♡ Hng♡”

Moans poured out in succession. Shiron felt the rough pulsation. Emotions that had been suppressed for years were anything but ordinary.

Thump thump.

Siriel’s heartbeat was palpable in Shiron’s hand.

Siriel’s face, looking up, seemed completely lost and mentally absent. Her eyes were tightly shut in excitement, and her red lips, dribbling saliva, echoed a bold declaration of love that resonated in Shiron’s mind.

More than the pleasure in his groin, stronger emotions filled Shiron’s mind. He decided to feel the soft, tender sensation in his hands more actively.

What he had to do now was to properly respond to Siriel’s love. Shiron decided to roughly tease Siriel’s breasts.

“Hngg. Huuu♡”

Kneading her soft breasts, he moved his fingers to pinch the hardening nipples.

“Hiiik!”

A proper reaction followed.

“Hiiik♡ Hiiik♡ Ngh♡ Haaang♡ “

Siriel’s body jolted, squeezing her vagina tight around the penis every time her nipples were pinched.

The girl riding on top of Shiron, who he always thought of as cute, was now a matured woman responding honestly to the pleasure.

Siriel, emitting lewd moans, gained confidence seeing Shiron properly enjoying her body. The hesitation in her actions disappeared.

Siriel began moving her ticklish lower abdomen and aching pelvis more vigorously. Additionally, she intertwined her fingers with his.

Leaning her upper body against his broad chest, she kissed his sweetly exhaling mouth.

“Smooch, slurp♡, smooch♡.”

The hesitation vanished not only for Siriel but also for Shiron. His heart, melting as much as his sister’s wet vagina, actively responded to Siriel’s tongue.

The tongue felt even hotter than before. Her well-developed chest rubbed against his, the hard nipples brushing against his skin.

“Mmm, I love you, brother♡. I love you♡. Smooch♡ slurp♡”

Siriel eagerly sucked Shiron’s saliva. It was sweet, so sweet. Unlike the tingling pleasure felt from the penis, the saliva of her beloved offered only pure bliss.

Before inserting his penis into her vagina, Shiron’s tongue had been stiff, but now it responded properly to Siriel’s warm, soft tongue.

Shiron pushed his tongue past Siriel’s lips.

Siriel was startled by the sudden intrusion of the large tongue.

“Mmm…♡”

Siriel tightly closed her eyes and matched his desires.

It felt good.

So good it drove her crazy.

Greater pleasure than the one coming from the lower body surged from Siriel’s mouth.

Breath was sweet.

Saliva was sweet.

Siriel fully accepted the tongue rummaging through her mouth.

No matter how big Siriel was, she was still a woman. Shiron’s thick tongue teased the small tongue nestled shyly in her mouth, as if it were as big as his penis.

“Slurp♡, slurp, slurp♡.”

Her eyes gently closed, Siriel joyfully matched her brother’s teasing.

“Slurp♡, slurp. Huum♡.”

This time, Shiron’s tongue explored Siriel’s mouth. Not only her tongue but also her white, neat teeth were licked all over. He even tapped her sweet uvula. Each time, a rough breath escaped, drawing amusing reactions.

Squish, squelch.

Touching the uvula usually causes gagging, but Siriel showed no such reaction. Instead, she opened her throat wide as if to swallow his tongue.

“Slurp♡, huu, slurp♡, smooch♡, slurp♡.”

As their sticky saliva mixed, their connected lower bodies grew hotter.

Siriel felt Shiron’s penis constantly swelling inside her belly, bringing her happiness.

Thump, thump, the pulse pounding against her abdomen felt like a knock urging her womb to open.

He couldn’t take it anymore.

Shiron released their intertwined hands and embraced Siriel’s back. Holding her well-shaped legs tightly, he rolled onto the black sandy ground, aligning their belly buttons.

He tightened his strained lower abdomen. The heated vagina wriggled as if urging for ejaculation. However, Shiron had no intention of climaxing so easily.

No matter how much Siriel wanted him to ejaculate, Shiron wanted her to experience proper pleasure.

After rolling several times on the sandy ground, Shiron regained the mounting position over Siriel.

It didn’t end there. He pressed her down with his weight, stretching his legs and rubbing his groin against Siriel’s vagina with even greater force.

‘…Finally, brother too!’

“Hnng♡”

She couldn’t say much because they were kissing, but Siriel let out an ecstatic moan at his active behavior.

Siriel also actively wrapped her legs around Shiron’s waist. Pressing her heels into his buttocks to help him ejaculate more was just a bonus.

It wasn’t something she had learned. Siriel instinctively realized how to urge a man to ejaculate.

Thanks to the aggressive squeezing, Shiron could no longer hold back.

At that moment, his penis swelled even larger.

Siriel’s vagina squeezed the penis even tighter.

His penis, held by her lower lips, began to twitch more frequently. Inside the warm vagina, it seemed ready to spill white liquid at any moment.

Twitch, twitch, twitch, twitch.

“Hnnng♡”

Siriel let out a fierce moan from the throbbing meat stake inside her belly. Even now, as they continued to kiss and intertwine their tongues, the vibrations from her throat were fully felt.

Finally, the urge to ejaculate became unbearable, and the hands holding Siriel’s body tightened to prevent her from escaping.

Shiron squeezed Siriel tightly. It was a pressure that an ordinary person couldn’t withstand, but Siriel was sturdy. She only felt it as a pleasant pressure.

Rumble! Rumble!

The sticky, thick semen that had been eager to come out poured into Siriel’s cervix. It wasn’t just that; the cervix, which was in contact with the glans, sucked up the semen as if it wouldn’t miss a single drop.

Siriel sighed blissfully at the warm sensation spreading inside her belly. Shiron swallowed all of Siriel’s sweet breath.

“Puh…♡”

The long kiss ended. Their tongues, which had been longing for each other, parted regretfully, and a clear thread of saliva stretched between their separated lips.

Soon, tears began to well up in Siriel’s eyes. Just as her previously empty heart was now filled with intense, proven love, so was her womb.

“Brother. I…”

As her belly filled up, Siriel opened her eyes wide. Shiron, putting strength into his tingling groin, met her gaze.

“Haa… Why?”

“I’m sorry for being so childish.”

An apology without context. It was a judgment that it might be better to apologize now. Human relationships weren’t simple enough to be happily resolved just by having sex.

Siriel bit her lower lip as she apologized. Unlike earlier when she was filled with dirty emotions, her now happy mind thought obediently towards her brother.

If Siriel had intended to tie Shiron down and monopolize him, his limbs wouldn’t be intact now.

There was a moment when she considered tying Shiron down for life, but ultimately, what Siriel wanted was Shiron’s happiness.

“I think I’ve really lost my mind…”

As long as she had a place in that happiness, that was enough for Siriel.

It wasn’t just about material elements but also about the mental part, so it was natural for regret to come late. Siriel wasn’t so reckless as to not know that just because you possess someone’s body doesn’t mean you possess their heart…

“I made a mistake.”

“…Hoo.”

Shiron gently stroked Siriel’s head as she apologized.

Was he forgiving her?

Was this going to pass smoothly? Siriel felt so happy she thought her heart might stop. After stroking her for a long time, Shiron suddenly straightened up.

However, contrary to her expectations, Shiron’s expression was stiff.

“Is ‘sorry’ all you can say?”

“…Huh?”

“Is ‘sorry’ all you have to say?”

Shiron grabbed the back of Siriel’s head roughly.

Startled by his rough touch, Siriel’s vagina, still holding his penis, twitched. Her vagina squeezed even tighter, as if trying to prevent her brother’s penis from escaping.

“Sorry…”

Defeated, Siriel hugged her chest tightly. Her well-developed chest changed shape lewdly.

Looking up at Shiron’s face, she twitched her vagina. It was too dark to clearly see his expression. Was he angry, or was he joking? It was ambiguous.

After a moment of silence, Shiron spoke seriously.

“…If you’re sorry, spread your legs.”

Shiron supported Siriel’s back and sat her up straight.

“Relax your body. I want to do more, but it’s too tight to move my hips.”

“Brother!!”

Siriel shouted loudly. She thought he might be angry, but it was just a mischievous joke. Feeling betrayed by being teased in such an embarrassing way, Siriel pounded Shiron’s chest.

Thud! She hit him so hard that her vagina walls clenched, making the penis slip out.

As the semen plug came out, the white semen also spilled out in a lewd manner.

“Again, again! You’re so mean♡!”

“So, are you not going to spread your legs? Don’t you want to have more sex?”

“I’ll spread them!”

Although she felt a bit sulky, Siriel spread her legs wide with a happy heart. Though the rough, obsessive sex was surprisingly good, what she truly wanted was tender, loving sex that connected their hearts. This feeling couldn’t be described in words. Because of the contrast with the feelings from just moments ago, Siriel’s face loosened happily.

“Hurry, hurry and thrust into my vagina♡”

Siriel pleaded with her vagina opening and closing, asking for the penis. Shiron pinched his cute little sister’s plump, swollen breasts.

“Hnng♡!”

A moan escaped, and at the same time, the penis was thrust in.

Despite having ejaculated once, the penis hadn’t shrunk at all and slid right into the vagina that had been dripping semen.

Squelch♡-

Their groins clashed. The glans scraped against the soft vaginal walls. Squelch- The mixture of love nectar and semen juices clung to the glans and were pulled out.

However, Siriel wasn’t disappointed. This was just a preliminary process to insert new semen. Now that she confirmed Shiron’s heart had melted, she had no more fear.

“Haa… Haa… Brother. I love you♡”

“I get it, so stop saying it. Aren’t you tired of it?”

“I’m not tired of it! I love you! I love you! I love you! I said I love you♡!”

Siriel shouted even louder than before.

“Thrust into my vagina♡! Make it a mess♡! Sex♡! Have sex with me♡! Make me pregnant♡!”

The words of love echoed off the walls and resonated in her head. Siriel didn’t check what she was saying, freely speaking words she normally wouldn’t dare say out loud.

Shiron, holding his dizzy head, pinched Siriel’s nipple again.

“Hnnng♡!”

“What do you mean pregnant! That’s absolutely not happening!”

“Why? Why not?! I want to have brother’s baby!”

Siriel whined, and Shiron grabbed his immature sister’s hand.

In his hand was a small, pretty box.

“If you get pregnant, we can’t have sex anymore.”

Squelch- Click-

Shiron thrust his hips while opening the ring box.

Squelch- Squelch-

“…Brother?”

Amidst the rushing pleasure and darkness, Siriel caught sight of the sparkling light.

“Brother… I’m so happy I might die…”

“What about the Knights if you get pregnant?”

“I’ll just be brother’s exclusive slave… brother’s exclusive vagina sex slave female knight♡”

“Stop talking nonsense. And if you get pregnant… Anyway, there are many things we can’t do. So please be satisfied with this.”

Creak creak creak creak.

Was it fingers or the vagina? It was a sound impossible to identify.

Shiron slipped the ring onto her hand, now covered in a mix of vaginal fluid and semen.

“Will you marry me?”

“…”

Tears welled up in Siriel’s beautiful eyes and began to fall. The tears, glittering more than the diamond on the ring, fell. Siriel tightly closed her eyes and clenched her vagina.

“There’s no answer…”

“Do I need to answer?! Saying yes is obvious!”

As soon as she gave permission, his penis thrust deeply. The ring was pushed further onto her finger.

“Hnng♡”

The sticky liquid-soaked vagina immediately sent a thrilling pleasure up Siriel’s spine. She almost rolled her eyes back. She was so happy. She felt like she could die from happiness!

“Ah… Haaang♡!”

Squish♡ Squish♡ Squish♡ Squish♡

Thrust♡ Thrust♡ Squish♡ Squish♡

Thrust♡ Thrust♡ Squish♡ Squish♡

Shiron pounded his hips into Siriel’s groin. It felt like an earthquake was shaking the ground, and dust fell from the ceiling.

However, Siriel didn’t feel any pain. Only ecstatic pleasure swirled in her head.

Thrust♡ Thrust♡

Shiron continued pounding without pause.

Thrust♡ Thrust♡

Siriel clung to the penis with a stronger grip than before.

Whenever he tried to pull out, her flesh clung to him as if not wanting to let go. When she was conscious, she could control it by tightening and loosening, but now, lost in happiness, she couldn’t control her vagina.

Each time this happened, Shiron would bite Siriel’s chest, then lift his upper body to kiss her. At this rate, her vagina would be a mess. She shouldn’t be bedridden with a sore vagina the next day, should she?

Whenever her chest was bitten, Siriel felt a thrilling and happy pleasure. And the kissing was another delight.

“Aang… Haang…♡”

Siriel was just… just happy. She lost sensation in her fingertips. She was so happy that she couldn’t distinguish whether this was heaven or reality, feeling a strange sensation as her vision turned white.

“O… Brother.”

“Why?”

“I feel like I’m going to die. If I have to die, I want to die in your arms…”

“…Siriel?”

Wondering what she was talking about, Shiron stopped his moving hips. Siriel barely managed to move her numb hands to wrap around Shiron’s back.

“O-Brother, don’t stop…”

“O-okay.”

Hnnng♡! Hnnng♡!

Thanks to the momentary pause, Siriel could let out cute little moans again.

Smooch-

Relieved, Shiron devoted himself to savoring Siriel’s breasts.

“Hnnng♡! Hnnng♡!”

Thrust- Thrust-

“Hnnng… Hnnng♡! Hnng… Hng♡!”

Siriel moaned with renewed pleasure.

“Hnng… Hnng♡! Haaanng♡, Haang♡!”

Every time her well-developed breasts were toyed with by his mouth, her tightly squeezing vagina would twitch and repeat its lewd tightening.

Thrust!

The more this happened, the harder Shiron thrust his hips.

Thrust! Thrust! Thrust!

Siriel averted her eyes from the tingling sensation in her vagina.

Her plump vaginal walls tingled. So did the folds deeper inside.

With intense friction and already heated body temperature, Siriel’s insides melted stickily.

“O, Brother.”

“Huh, why?”

“Say you love me again.”

Siriel decided to whine one last time. She felt like she would stop breathing, so she wanted to hear the words she longed for one last time before she died.

“I love you.”

Shiron brought his mouth to Siriel’s ear and whispered love with a deep voice.

“How many times do I have to say it for you to understand?”

“Brother-nghhhh!”

Siriel trembled violently with happiness at the voice tickling her ear. She felt like she could die from the happiness of having her vagina filled with brother’s penis. Feeling like all the holes in her body had become brother’s made her feel so happy she thought she might die.

“I love you too♡♡!!”

Her eagerness to receive every drop of semen was palpable. The stiff glans touched her plump cervix, which seemed to suck and fondle the glans as if not wanting to miss a single drop.

Her tightly squeezing vagina.

Her tightly squeezing legs seemed to scream that they would consume all of brother’s semen.

Thrust!

His prostate ached.

Thrust!

The urge to ejaculate surged.

The rhythm of his moving hips slowed. Siriel instinctively realized what that meant and covered Shiron’s mouth with her own.

Smooch♡ Smooch. Slurp♡.

Then,

Rumble! Rumble!

With a tingling, aching sensation, the throbbing penis spurted fresh semen.

New semen filled Siriel’s womb to the brim.

Squish- And even after that, Siriel’s vagina didn’t get a break.

Just when it seemed filled with semen, new semen poured in again, and they kissed so much that even Shiron’s body had blue bruises here and there.

Continuously like that… Siriel shivered all night long in immense pleasure, even dripping with love juices until she fainted from dizziness.

Squish-

Creak-

Not knowing that golden eyes were watching her.
