Chapter 167: Deep Night at Helium (2)

The position commonly referred to as the "69 position" is one that Marie and Isaac have tried many times before. Unsurprisingly, it was Isaac who first suggested it, as this position is not well-known.

Initially, Marie felt embarrassed about assuming a position where her genitals, including the anus, would be presented in front of a man's face. However, after becoming accustomed to it, she began to enjoy it. In addition, they have been exploring various other positions that complement each other well.

However, it is important to maintain cleanliness, as a lack of hygiene could result in unpleasant odors. This position should always be performed after thorough cleaning.

Lick!

"Ah!"

As Isaac lightly licked Cecily's vagina with his tongue, her body trembled, and there was a momentary surge of strength in Cecily's hand holding his erection.

It was a completely different sensation from when she masturbated just a moment ago, as if electric currents were flowing through her brain. She had long since cast aside any shame, but the act of her beloved man licking her genitals was a powerful stimulus for Cecily.

Momentarily stunned by the unfamiliar pleasure, she regained her breath and used her tongue to lick the object in front of her eyes. She lovingly touched it with both hands and used her tongue and mouth to savor it like candy.

Lick!

"Ah!"

"Mmm... slurp... mmm..."

"Ah! Huh!"

But as Isaac began to lick her clitoris, Cecily found it difficult to contain herself. She could feel a tingling sensation in her lower abdomen, and her juices flowed profusely.

Her legs weakened to the point where she wanted to surrender her body completely. The patience she had cultivated to overcome her inner demons was meaningless.

This wasn't some inner evil, it was the "pleasure" that her beloved lover was bestowing upon her. It was the first time in over a century that someone other than herself was using their mouth to pleasure her.

'It has a subtle sweetness to it.'

As Celily buried her face in Isaac's crotch, Isaac savored her nectar as he licked her mound. The taste and aroma of love juices vary depending on the person.

If Marie's love juices were salty and tangy like lemons, Cecily emitted a fruity scent or rather, a sweet taste.

As a princess of Helium, she must have eaten various kinds of food, but the sweetness wouldn't have played a significant role in her origin. It was a persuasive hypothesis since she sucked on Isaac like an ice cream, claiming it tasted delicious.

With his eyes closed, Isaac greedily devoured Cecily's love juices. Instead of falling drop by drop like water droplets, they flowed continuously like a faucet, quickly saturating the area around his mouth.

"Churp, chwup, jyup!"

"Hahk! Hahng! Ahh!"

Now Cecily only moaned instead of sucking on Isaac's penis. Although he could bring her to climax by licking her mound, Isaac was experienced in countless sexual encounters with Marie.

He knew that a woman's climax doesn't explode all at once like a man's but builds up slowly like climbing stairs until it reaches its peak. Unlike the so-called "post-sex nap" that men experience, a woman's climax lasts for a long time.

So when Cecily stopped fellatio, Isaac would stop as well and, once she regained her senses and took something into her mouth, he would lick her clit.

Although she didn't explicitly demand it, by now Cecily must have realized that if she didn't caress Isaac's penis, this pleasure would disappear forever.

"Uguk! Oooh! Jyup! Chup!"

As soon as Cecily became aware of that fact, she tightly closed her eyes and accepted Isaac's member deeply into her throat. Cecily, without forcibly inserting his rod, moved her head back and forth as if diving underwater.

At the same time, Isaac was also fervently exploring her pink treasure. Not only did he caress her with his mouth, but he also handled her delicate curves like fragile glass. Her peach-shaped buttocks were so well-formed that even the act of caressing them had an addictive quality.

Slurp!

"Oo-goo-wup!"

Before long, as if becoming accustomed to licking with his mouth, Isaac widened the entrance of Cecily's vagina with his thumb and pushed his tongue deep inside. Cecily widened her eyes and stiffened her body as soon as Isaac's tongue penetrated her insides.

The sensation inside her was not like something hard and rigid but rather the soft and pliable texture unique to a tongue. It was a completely different sensation from when she had masturbated just moments ago.

Cecily firmly gripped Isaac's erect member, plunging it deep into her throat, and clenched her fist tightly. The electrifying sensation rising from below traveled through her lower abdomen, up her spine, and pierced her brain.

This was dangerous as it was. However, she couldn't stop.

With her eyes wide open, Cecily awaited the signal for Isaac to release...

Pop!

"Ooo-ooh! Puh-ha! Hoo-aahh!!"

As soon as Isaac touched her swollen glands with his hand, it exploded intensely.

Squelch! Squelch! Squelch!

"Haa-aaah! Haa-ng! Uwaa-ang! Aa-ang!"

When touched, Cecily, released a scream that was soaked in delight. From her depths, love juices burst forth like a fountain, dampening Isaac's face.

However, Isaac remained undeterred and kept his tongue inserted at the entrance of Cecily's intimate parts. Instead, he stimulated her nether region by using his index and middle fingers, savoring the love juices as if they were holy water.

As if a dam had burst, Cecily trembled sporadically, reaching the climax. The climax gifted to her by another, a man she loves, deviated from self-pleasure, taking a different course.

"Ah... hah... haa..."

Cecily buries her face in Isaac's groin, controlling her breath. Her jet-black hair flowed like a curtain, and her crimson eyes lost focus.

Yet, Isaac's member, firmly grasped in her hand, revealed Cecily's lewdness. Even in the midst of a chaotic mind caused by the climax, she extended her tongue and skillfully stroked the pillar.

Isaac appreciated Cecily's lasciviousness, which may rival Marie's or even exceed it. They haven't even entered the main event, but she was already thirsty for more.

Thus, he cautiously shifted Cecily's buttocks to the side. Even when moving her legs onto the bed, Cecily never once considered detaching her face from his erection.

"Noona, I understand you want to continue sucking, but we should stop now."

"Meanie... I want to eat more cock... I haven't had enough... I'm drooling."

Despite being absent-minded, Cecily continued to seek only Isaac's member. Perhaps it's because she's a succubus, but her resilience is no joke.

Marie couldn't even move after reaching climax, but Cecily seemed completely fine. Isaac chuckled wryly and restrained her with a gentle voice.

"I'll feed you more without restraint later, so for now, let's stop."

"Heehee..."

Isaac harshly pushed Cecily away, causing her to fall helplessly on the bed. Her expression was gloomy, but her gaze remained fixed on Isaac's crotch.

Suddenly, Isaac grabbed Cecily's slender shoulders and spun her body around. Cecily turned her head and faced Isaac's face.

Even in the darkness, Cecily blinked her eyes a couple of times at Isaac's shining golden eyes and then smiled mischievously. Then she extended her lips, demanding a kiss.

Although his own desire had waned, Isaac fulfilled her request willingly. After all, his semen would reach its destination and satisfy the woman he loved, so he had no hesitation.

Furthermore, Cecily's mouth exuded a sweet fragrance, reminiscent of a unique fruity aroma that was also present in her saliva.

As if comparing herself to a dessert, Cecily's body was like a sweet fruit dessert itself.

"Mm, softer... deeper... mm..."

While kissing Isaac, Cecily arched her back, feeling the softness of the bed enveloping her head.

Isaac laid Cecily on the bed and continued kissing her for a while before silently parting their lips. A trail of silver saliva stretched and then weakly broke apart.

Eventually, he gazed at Cecily lying on the bed. Her large and perfectly shaped breasts, despite lying down, maintained their roundness, and the curve of her waist and hips was truly a work of art.

In addition to this, the secret garden, soaked with the nectar. Isaac swallowed his saliva and gently placed his object on Cecily's abdomen.

"Wow..."

Cecily marveled at the size of the object, which almost reached her belly button. Could that really enter inside her? If it did, how would it feel?

Could she experience a more intense pleasure than the one she felt earlier? With an expression of anticipation, she pressed Isaac's object against her abdomen.

As Isaac's object touched her flawless abdomen, she could feel the sensation perfectly. She had thought about it before, but it was hot and solid like an iron rod heated in fire, just as Marie had described.

'Marie... She said she couldn't take it all, right?'

Could she really accept all of that? She was taller than Marie and her pelvis was well developed, so maybe it was possible. Cecily lovingly caressed Isaac's penis, then raised her gaze. Isaac was smiling gently, as if waiting for permission.

"...Isaac."

"Yeah, Noona?"

"I love you. So..."

Suddenly, with a trembling voice, Cecily confessed her love and used both hands to widen her vaginal entrance. The fluid that had been lingering inside her vagina poured out.

Then, with an expression that seemed consumed by desire, she earnestly begged Isaac. Her red eyes emitted an even more intense gleam.

"Please... ravage me completely, Isaac."

"... ..."

"You can handle me however you want. Treat me roughly. So, please... please put it in."

Just these words were enough to make Isaac's object throb with anticipation.

"My body and heart... belong to you, Isaac ♡"

With a quick decision, Isaac took action, breathing heavily. Normally, he would have caressed, but with the flood that occurred, there was no need for foreplay.

Without delay, he grasped the rod with one hand and began to search for the entrance. As an experienced person, finding the entrance was easy.

Finally, the tip touched the entrance, and Cecily tightly gripped the bedsheet in anticipation of the imminent pleasure. Her heart pounded violently, and her breathing became rapid.

"... Nuoona."

"Yes, yes. What is it?"

"You're really a pervert, Noona."

As he spoke, Isaac smirked.

Sst!

Without hesitation, he pushed the penis inside.

"Ah...!"

As Isaac's object filled her, Cecily's tongue slipped out of her mouth. Her waist arched like a bow, and her grip on the bed sheets tightened.

Due to the rapid and penetrating entry without taking it slowly, there was some pain, but it became meaningless due to the pleasure that came like a tidal wave afterward.

The sensation of a hot iron rod, hard yet fiery, filled her lower abdomen completely. Cecily trembled and then forced her gaze downward with difficulty.

Most of that enormous erection had disappeared. She shifted her gaze with a happy smile, knowing that she had become one with the man she loved.

Isaac, too, looked down at himself with his characteristic deep smile.

"Ah, Isaac, you're..."

"Yeah, noona."

"I love you... really... I love you..."

Cecily confessed her love once again, spreading her arms wide. Isaac obliged by lowering his upper body, embracing her as she desired.

As their bodies entwined, Cecily's ample bosom also became beautifully wrinkled. Isaac appreciated the wonderful feel of her breasts and enjoyed breaking down her barrier.

Naturally, it was tight like a virgins, but it also felt soft as it wrapped around him. The thick secretions provided a different sensation from Marie's.

Most surprisingly, Cecily accommodated Isaac's massive girth for the most part. While there was a slight remnant at the base, she didn't feel his glans touching her cervix.

This aspect gave Isaac a new stimulus. Gently wiping Cecily's face, he asked quietly,

"Does it hurt?"

"It just feels good... so please, move..."

"Yeah, got it. Here we go."

Isaac lightly kissed Cecily and raised his upper body slightly. Instead of pulling back, he moved forward slightly.

Squelch—

"Kyahh!"

With that, even the remaining base disappeared completely, and the glans collided with Cecily's cervix. Cecily felt a sensation as if electric currents were flowing throughout her body.

Thud—

"Uuhh..."

After Isaac pulled his hips back, the cock that had filled her insides also disappeared. Cecily, while emitting a satisfied moan, felt a sense of emptiness as the bat scraped against the walls and retreated.

It's natural to feel empty when something that had filled every space disappears. Finally, just before the glans was fully withdrawn.

Jiggle—!

"Aaahh!!"

Isaac forcefully thrust his waist and penetrated inside once again. The glans collided with the cervix once more, and Cecily let out a scream filled with pleasure.

Thud—

"Uhhuung..."

Slowly pull out.

Thrust!

"Ah-ahh!!"

He thrust forcefully.

Squelch!

"Ah, mmh..."

He withdrew slowly once again.

Squish!

"Uhhhh!!"

He thrust even harder once more.

It was a process to become accustomed, and every time, Cecily let out moans of pleasure. She had already fully adapted to Isaac's actions, accepting nothing but pleasure.

In response, Isaac moved slowly and teasingly, arching his lower back. Mixed with the flow of fluids, evidence of her virginity, blood trickled out.

However, Cecily seemed to have a body that had already experienced this several times, whether due to her innate nature or not. It seemed fine to proceed as they always did with Marie.

Normally, he would proceed with care and consideration, but Cecily seemed not to require it. Nevertheless, he had to make her feel the climax.

Thrust!

"Mmhh...!"

Isaac lifted his upper body completely and firmly grasped Cecily's breasts, which he had longed to play with. His hands were buried in the vast mound of flesh.

While teasing her plump chest freely, he gently moved his waist. He would delicately touch or pull on her pointed pink nipples with his fingers.

To make it a mess just the way she wanted, he began to handle her roughly.

Thump! Thump! Thump! Thud!

"Ah! Oh! Ahh! Yeah!!"

As her chest was being teased, Cecily moaned continuously while repeating the waist movements. Due to excessive arousal, the sound of moistness started to emerge.

Isaac tightly grasped Cecily's large breasts as handles and eagerly devoured them. Based on their previous sexual encounters, he incorporated not only simple repetition but also controlled the rhythm.

If he sensed that Cecily was approaching climax, he deliberately slowed down, and when she seemed to relax a little, he thrust forcefully.

It wasn't only a crude exercise like their first night with Marie, but Isaac also added techniques to provide Cecily with extreme pleasure.

Thud! Thud! Slap!

"Ah! Mmm! Mmh. Mm. Mwah! Ah..."

To prevent boredom, they occasionally kissed. As Isaac explored her mouth, Cecily responded willingly. Moreover, she wrapped her legs around Isaac's waist to further stimulate him.

Even amidst the intertwining of their tongues, like entwined snakes, Isaac relentlessly thrust into Cecily's vagina. Her mouth was teased with kisses, her breasts were handled with both hands, and finally, her lower entrance was occupied by Isaac's penis.

The three rhythms harmonized perfectly, gradually reaching their limit. Tears welled up in Cecily's eyes, and her vaginal walls contracted forcefully.

Isaac gradually realized that the climax was approaching and examined her face. Her red eyes were rising, revealing the whites.

If that's the case, everything left will be released. While maintaining the kiss, he lowered the hand that had been gripping her chest.

Passing her lower abdomen, which was already wet with fluids, he arrived at Cecily's clit. He lightly touched the sensitive spot he had confirmed earlier.

"Ah! Hng!"

As soon as he touched her sensitive spot, Cecily's body trembled. It felt like an electric current running through her spine, striking her brain, just as before.

But this wasn't the end. Isaac strengthened his grip on her muscles, making her more tightly held, and he roughly stimulated her core with his hand.

Throb! Throb! Twitch! Twitch!

"Ah! Ah! Huh! Haah! Kyaaah!"

Cecily was now writhing and screaming almost uncontrollably. Something was building up from her head, signaling the imminent climax.

In response, Isaac withdrew his hips and forcefully thrust them back in an instant.

Squelch!

"Kyaaaah!"

The feeling of their genitals colliding with each other finally brought Cecily to her climax. Her waist arched like a bow, and the bed, unable to withstand the strong force, shook vigorously.

Pusshii!!

Cecily's long, slender legs that wrapped around Isaac's waist were trembling, and ejaculation gushed like a fountain from the still-filled vagina.

There was a significantly larger amount compared to what was done orally, and the bedsheet was soaking wet.

Cecily had reached orgasm, gasping for breath.

"Hmm...! Ahh...! Mmm..."

Squelch~

"Huh!?"

But the issue wasn't Isaac. It was Cecily realizing that Isaac's waist wasn't moving slowly and deliberately while she was catching her breath.

Only then did she realize that Isaac hadn't climaxed yet.

The real show was about to begin.

Isaac gently stroked Cecily's cheek, which was trembling with fear. Cecily, who was already highly aroused due to the orgasm, trembled as he wiped her cheek.

A woman's orgasm isn't easy, and even coming down from it is slow. So Cecily's lascivious body is currently in an extremely sensitive state.

It means that she's suitable for continuously experiencing the pleasure that feels like her brain is melting.

"Didn't you say, 'Make a mess of me'?"

"Ah, Isaac..."

Cecily called Isaac's name with a trembling voice. Isaac affectionately wiped her cheek and then put his finger in her mouth.

A few months ago, when Cecily and I were alone at the cafe, she was the one who sucked on my fingers first. However, now Isaac directly put them in her mouth.

Cecily faced Isaac while sucking on his fingers, from which a sweet scent spread due to the saliva. His penis, which had entered her vagina, still remained firm and proud.

"Ah... Mmm... Agh..."

Thump!

"Oof!"

Isaac's waist jerked once, causing her to widen her eyes. However, her mouth was blocked by Isaac's fingers, preventing her from making any moaning sounds.

Thump! Thump! Squelch! Slurp!

"Huff! Ooh! Ahh! Eeuung!"

Isaac continued to tease Cecily's mouth with his fingers, back and forth. With each insertion, water sprayed in all directions.

Cecily, already sensitive due to the peak of pleasure, sensed another wave building up. Not only was the act of insertion pleasurable, but also teasing her mouth brought delight, and squeezing her chest was no different.

She wondered if she might actually die. The stamina of a demon mattered in terms of endurance and wounds, not this kind of climax. If anything, it seemed like succubus blood prevented her from easily descending from such heights.

Moreover, with the overlapping evil cycle, her current state of orgasm made her entire body feel like it was filled with erogenous zones.

"Eeung. Ahh. Isaac, you are..."

"Why? What's wrong, Noona?"

"I said something wrong. I was wrong..."

Due to the unexpectedly strong stimulation, Cecily eventually apologized. However, Isaac countered with a smirk.

"But why are you laughing?"

"Uh... it's nothing..."

Despite denying it, Cecily had a happy smile on her face. Her words were merely a facade, as her true desires were evident.

In response, Isaac removed his fingers from Cecily's mouth and decided to change positions. First, he temporarily removed the rod from her vagina and then flipped her body over.

Due to the relentless pleasure that repeatedly surged, Cecily had no strength left to resist, and her face was pressed against the bed.

Then, Isaac wiped the peach-shaped, beautifully contoured buttocks before inserting himself. Before penetration, he wore a devilish smile and extended his hands towards Cecily's horns, not her waist.

He forcibly grasped her horns like handles and lifted them up. As Isaac held onto the horns and forcefully lifted, Cecily, in her frenzy, used both arms to support her upper body.

Thud!!

"Ah...ahh!!"

Without any warning, Isaac inserted himself into Cecily's vagina. Once again, an overwhelming sensation pierced through her brain, causing Cecily to let out a moan. Since it went deeper than usual and stimulated the pleasure receptors inside her vagina properly, this position brought even greater pleasure.

Slap! Slap! Thud! Thud!

"Uh-heung! Ah-heung! Ah-aang! Hoo-ang!"

Isaac watched Cecily's back as she writhed in pleasure. Her back muscles, extending in a straight line down the center, and the peach-shaped buttocks that flowed beneath her slender waistline were captivating.

Every time he struck, her large breasts jiggled and swayed, a truly magnificent sight.

'First, let's give it a try.'

Thanks to Mora's divine power, excluding the calming effects, Isaac's erection had been going strong for a long time. However, he couldn't leave it as it was, so he thought it would be good to release once.

Above all, one reason Mora granted divine power was to transmit it to Cecily as well. The method of transferring energy through sex has existed since ancient times.

Instead of delivering the final thrust, Isaac's attention was suddenly drawn to Cecily's tempting buttocks. They were plump and seemed incredibly inviting.

Well, he had asked her to make a mess anyway. A mischievous expression crossed his face. Besides, even with just one hand, it would be enough to hold onto the horns.

Then, raising his arms high towards the sky, Isaac...

Slap!

"Kyaaah!!"

He forcefully smacked Cecily's peach-shaped buttocks. As soon as her buttocks were struck, Cecily let out a mixture of a scream and a moan. At the same time, the tightness of her inner walls increased significantly. Unable to contain his excitement, Isaac continued to spank her buttocks.

Snap! Slap! Smack!

"Oooh! Aaah!! Uh-heung!!"

Every time Isaac spanked her buttocks, Cecily let out a scream of pleasure. Her vagina also contracted and relaxed repeatedly.

Thus, Isaac learned one thing. As if proving her plea to be violated in disarray, Cecily enjoyed being tormented.

She was nothing but a lascivious slut, not a demon princess, not anything other than a succubus itself.

Thud! Thud! Thud! Slap!

"Ah! Isaac-nim! Isaac-nim!! I, I..."

Cecily cried out, calling Isaac's name. Seeing her tongue sticking out was evidence that she was reaching another climax.

As the signal of his release approached, Isaac momentarily stopped spanking and shook his hips. Then, gripping her buttocks tightly instead of her horns, he thrust backward, lengthening his movements before violently pulling away.

Thud!!

"Ahhh!!!"

Cecily, with her tongue sticking out, experienced her third climax.

Drip... Drip... Drip...

Isaac also released his seed deep into Cecily's uterus. It was his second release, but the quantity was by no means small; it had actually increased.

Looking down while catching his breath, Isaac ejaculated inside Cecily, not Marie. Her buttocks were stained red, and Cecily's body trembled in excitement.

On the first night, could it feel this good? He slowly pulled out and slapped Cecily's buttocks coolly.

Smack!

"Haeng..."

Isaac felt the climax as Cecily trembled when he spanked her buttocks. Despite having ejaculated for the second time, Isaac still looked at his erect member.

Still not enough. With the accumulation of steady effort and the divine power from Mora, it was only natural.

The night is still young. Isaac pressed his face against the bed and approached the trembling Cecily.

"Noona, can we do more?"

"Yes... we can do more."

Just moments ago, she seemed like she would faint, but for some reason, she quickly regained her stamina. Could it be that succubi regain their strength with the intake of semen?

If not, perhaps the divine power received from Mora was transferred to Cecily. It's possible that Cecily, not Isaac, is the dangerous one.

Isaac extended his member, feeling a sense of satisfaction in conquering Cecily, who is much stronger than himself and is even slated to be the next Demon Lord.

As a massive object approached her face, Cecily raised her body, flinching.

"I'll help you."

"Yes? Ah!"

Without any further conversation, Isaac grabbed Cecily's horns and began the act. Cecily's eyes widened as his penis filled her mouth, and she soon started trembling.

Push—

A distinct sound of bodily fluid being discharged could be heard below. Isaac grasped her horn and moved it up and down.

"Oog! Ooogh! Jyuup! Chwak! Ooguk!"

Tonight, there was no esteemed princess of Helium. There was only one lewd woman left.

"Ah... I'll go again."

"Chuwup! In... in my mouth..."

Plup plup

Isaac enjoyed a long night ejaculating inside Cecily's mouth.

"It tastes good... More... Give me more..."

"As you wish."

"Kyaaah!"

Cecily, who had an unforgettable first night, was no different.

Translators note:

Didn't think they would be into this...

Also decided not to change the sfx in those chapters as I had more than enough of my share looking up sfx for sex before.
