Ch.166Deep Night of Helium (1)

*Slurp- Slurp- Slurp-*

“Mmm… Issac. Issac… *slurp*…”

Cecilly straddled Issac’s thighs and hungrily devoured his lips. Their tongues intertwined intimately as they exchanged saliva.

Her body was already burning hot due to her mating cycle, but as they began kissing, it started to feel like a ball of fire. Not only that, but Issac’s manhood making its presence known below was increasingly stimulating her.

Even though they were just kissing, her brain felt like it was melting—what would happen if they went all the way?

To be honest, despite being in her mating cycle, Cecilly was still a virgin with no experience with men. Though she was continuing to kiss him hungrily following her instincts, there were bound to be inexperienced aspects.

And that was something Issac was well aware of.

*Slide-*

While holding Cecilly’s face and continuing their deep kiss, Issac slowly slid his hand downward. Past her delicate neck, arms and armpits, down to her slender waistline.

Cecilly’s body, already heated and hypersensitive, twitched at Issac’s gentle touch. Though their kiss didn’t break, she couldn’t stop herself from trembling.

Eventually, when Issac’s beautiful, slender hand moved past her waist and caressed her buttocks—

“Ahh!”

Cecilly let out an aroused moan. As their lips parted, the silver thread of saliva connecting them snapped.

Even with his mouth free, Issac didn’t stop caressing her buttocks. Instead, he used his other hand to tenderly handle Cecilly’s heated body as if it were a precious work of art.

There was one thing he had learned from his experience with Marie. When a woman becomes properly aroused, her body becomes extremely sensitive.

Especially in Cecilly’s case, she was already at the peak of arousal without needing additional foreplay. Evidence of this was how Issac’s thigh that Cecilly was sitting on wasn’t just damp—it was soaked.

As much as he wanted to take off his pants and fully explore Cecilly, tonight was her first night.

He planned to do his best to give her an unforgettable first experience and pleasure.

“Mmm…”

“Ahh… mmm…”

While the caressing continued, Issac brought his lips to Cecilly’s neck. She trembled and moaned at the soft lips touching her neck.

Following that, Issac moved downward, leaving kisses as if marking her—from her neck to her collarbone, and then to her dotted chest.

Just as he was about to kiss her nipple, barely covered by her underwear, Issac stopped there. As if teasing her, he didn’t go any lower but just circled around the area.

“Ahh! I-Issac…”

“Want more?”

Issac removed his lips from her breast and asked with a mischievous smile. His deep, dignified voice entering her ears made Cecilly look at him with a completely relaxed expression.

His golden eyes were staring directly at Cecilly, even in the darkness. She gathered her ragged breath and swallowed hard.

Treat me roughly. Make me cry out with even more pleasure than this. Cecilly’s heart was screaming loudly.

But the answer that came out of her mouth was completely different. A small part of her rationality remained, as her desires hadn’t completely taken over her brain yet.

“I… I want it. So…”

“Shouldn’t you pray first?”

“P-pray?”

Cecilly was momentarily confused by Issac’s sudden request to pray, but soon she understood why.

Before entering the palace, when she was arm in arm with Issac and talking alone, she had mentioned it. That tonight’s prayer would be quite different.

And that she could look forward to the content of the prayer. She herself had directly mentioned it.

“Do I have to… right now?”

“I won’t continue until I hear it.”

“…You’re being mean.”

“Think of it as karma for all the teasing you’ve done to me. If you don’t say it…”

“Ahh!”

Issac lightly grabbed Cecilly’s large breasts. She let out another moan at the sudden surprise attack.

While Cecilly was momentarily disoriented, Issac ravished her voluptuous breasts hidden beneath her underwear. If Marie’s breasts were soft like marshmallows, Cecilly’s had excellent elasticity.

Moreover, their enormous size made them perfect to play with like toys. He wanted to do all sorts of things with these breasts.

Addicted to the sensation, he remained silent for a while before bringing his lips close to Cecilly’s ear. Then, in a whispering voice, he said:

“I’ll just keep teasing you and end it there.”

“Mmm…”

“You said before, didn’t you? That you could give both your body and heart for me. So, go ahead.”

As Issac urged her, Cecilly pondered despite her dizziness.

It was paradoxical and humiliating. Praying to God while being caressed by the man she loved. What would Mora think if she saw this?

‘Maybe… she’d turn a blind eye just once?’

But her mind was already consumed by desire, making it hard to think properly. Besides, Mora was showing great favor to Issac.

As long as they weren’t committing sacrilege in the temple, Mora might overlook it. With this in mind, Cecilly put her hands together neatly and began to pray quietly.

“O-Oh, Mora, Goddess of Darkness and Rest… tonight…”

*Click-*

While praying with her eyes closed, Issac skillfully unhooked her bra. The bra that had been struggling to contain her massive breasts fell helplessly as soon as the hook was undone.

Cecilly’s body jerked significantly when her bra was undone. It felt good to have all the pressure on her chest removed, but she felt even more embarrassed.

The removal of the bra meant her bare breasts were fully exposed. Feeling somewhat ashamed, she neatly folded her arms, but it was impossible to cover those large breasts.

Not knowing that the more she did so, the more she would touch Issac, Cecilly recited the prayer with difficulty.

“…T-tonight, I am truly grateful for allowing me to spend my first night with the man I love. Please let that man…”

Desire or rationality? Cecilly couldn’t continue the last words, her lips trembling.

*Touch-*

“Ahh!”

“You should finish the prayer. Noona. That man?”

While Cecilly was still pondering, Issac grabbed her bare breasts and asked in a subtle voice. He stimulated her desire by gently rolling her nipple with his finger.

With his other hand, he caressed her buttocks and occasionally touched her intimate part. Although it was covered by a garter belt, she could feel it.

“Ahh… that man…”

“That man?”

“Me… mmm…!”

“Me?”

As Issac repeated each word after her, and simultaneously caressed her, Cecilly finally…

“M-mess me up…!”

“…”

“Please let him mess me up…!”

She passionately released the desire she had been holding back. After her prayer ended, Issac smiled deeply and then grabbed her chin, which she had lowered in embarrassment.

He slowly lifted her chin so their eyes met. Cecilly’s red eyes were already filled with sticky lust.

“Well done, Noona. Now…”

I’ll do as you wish.

As soon as those words ended, Issac pounced on Cecilly’s lips. Cecilly, now surrendering to her instincts, began to respond.

“*Slurp- Slurp-* Issac… *Slurp!*”

The deep kiss began again. But unlike before, Cecilly gently rocked her body back and forth, touching Issac’s manhood.

Noticing that Cecilly seemed to want his member, Issac subtly moved his hips backward and took off his pants. With the pants removed, only his underwear remained, but a mere piece of underwear couldn’t fully conceal Issac’s manhood.

Thanks to this, Cecilly stopped kissing and pulled her face away. Looking down, she admired with a dreamy expression.

“Ah…”

It’s big. Just as Marie had mentioned, it’s impressively large, almost ready to burst through the underwear.

That thing hidden inside Issac’s underwear would soon enter her intimate part. Though she was already wet, she wondered if it would fit.

And if it did enter, what would it feel like? She had heard that if there’s enough lubrication, unforgettable pleasure would come.

She wanted to put it inside right away. First night or not, she wanted to experience the pleasure that would satisfy her sticky desire right now.

Just imagining it was thrilling, and her lower abdomen tingled. Below, it was already flooding like a deluge.

These were the inner thoughts of Cecilly, who, like at the previous exhibition, had finally succumbed to her mating cycle and couldn’t suppress her instincts.

“Noona.”

“…”

“Do as you wish now. I’ll help you.”

Issac readily handed over the initiative to Cecilly. Originally, he had planned to lead, given it was her first night, but looking at Cecilly, it seemed unnecessary.

Cecilly was already consumed by desire. She was as bad, if not worse, than Marie, who had accumulated sexual desire.

Moreover, she had the blood of a succubus flowing in her. He planned to just watch, only helping with occasional caresses to keep her excitement up or when it was time for the main event.

With this, Cecilly lowered her gaze from Issac’s face to his groin. She saw the peak still standing tall without losing its strength.

“*Lick.*”

Cecilly licked her lips as if spotting prey. Her red eyes gleamed mischievously.

Following this, she moved away from Issac’s thighs she had been sitting on and backed up. Issac waited for her next move with a comfortable expression.

First, she pulled down her black frilly panties, and next, she undid the garter belt, which could be considered the main dessert, and lowered it.

Finally, Cecilly was completely naked without a single thread on her. Issac fully appreciated her naked body.

Her breasts, which had been consistently mentioned, maintained a beautiful shape without sagging despite their size, and her waistline and pelvis below formed soft curves as if sculpted.

Moreover, due to her demonic traits and consistent yoga practice, there wasn’t a single bit of excess fat, and her arms and legs were long and slender. Lastly, the black bush growing shyly below her lower abdomen.

Is this what they call heavenly beauty? His already erect member seemed to harden even more.

“Mmm~”

While Issac was appreciating her, Cecilly let out a seductive moan and moved. She then knelt down modestly and grabbed Issac’s underwear.

Guessing that she was about to remove it, Issac acted as she wanted. He slightly lifted his hips, and Cecilly, seizing the opportunity, began to remove his underwear.

Though the underwear got caught in the middle, soon Issac’s underwear was completely removed by Cecilly’s hands.

“Wow…”

“…”

As soon as she saw Issac’s member standing tall towards the sky, Cecilly exclaimed with genuine admiration. Marie had half-jokingly compared it to a claymore, but seeing the thing in front of her, it was no exaggeration.

Was it because of the succubus blood flowing in her? The smell emanating from Issac’s member stimulated her sense of smell.

It wasn’t sweet but had a strong concentration, yet it made her think ‘delicious’. Cecilly brought her face closer to Issac’s member and sniffed.

“*Sniff. Sniff sniff.* Ahh… this is Issac’s cock… it smells good…”

“…Where did you learn to say that?”

When Cecilly used the vulgar term, Issac asked in a disgruntled voice. He hadn’t expected her to directly call it a cock.

But Cecilly tilted her head as if wondering what the problem was and asked back:

“I called a cock a cock, is there a problem?”

“…No.”

With such an innocent expression saying ‘cock’… it’s incredibly arousing.

The situation where the Princess of Helium was smelling his member and speaking vulgarly—anyone would be turned on.

*Slide-*

Cecilly’s hand carefully wrapped around Issac’s member. It was too thick to grasp with one hand, so she had to use both.

Cecilly wrapped it with both hands and then slowly and gently moved up and down. It felt like touching a piece of iron heated in fire.

“It’s hot… and hard…”

“Mmm…”

Issac let out a weak moan as Cecilly gave him a handjob. Though her hands felt a bit rough from sword training, the mere fact that Cecilly was giving him a handjob was intensely stimulating.

She is a virgin with no experience. But her emanating sexiness and each of these bold actions drove him crazy.

*Lick-*

While giving him a handjob, Cecilly licked the shaft with her tongue. She then smacked her lips as if savoring the taste, and her eyes suddenly lit up.

Delicious. It wasn’t a lie; it was genuinely delicious.

This was a phenomenon that occurred as the succubus blood flowing in her body manifested, coupled with her mating cycle. The distinctive strong scent and taste from a man’s member whetted Cecilly’s appetite.

She swallowed hard and then opened her mouth wide to take the entire glans.

“Mmm. *Slurp. Slurp.* Heh. *Slurp. Lick.*”

“Ahh…”

Cecilly repeatedly sucked, licked, sucked, and licked. She handled it carefully, like eating a candy that wouldn’t melt, to avoid hurting the member.

Not stopping there, she diligently moved her hand back and forth on the parts she couldn’t take into her mouth. Thanks to being covered in saliva, it moved more smoothly.

Normally, one’s first fellatio would be clumsy, but Cecilly was unexpectedly skilled for a first-timer.

From the beginning, fellatio is an act that might cause aversion, but Cecilly took the initiative herself.

Whether it was the succubus bloodline in her body that imprinted such acts, Issac found it to be a great pleasure.

“Noona…”

“*Slurp. Slurp. Slurp.*”

When Issac placed his hand on her horn, Cecilly flinched for a moment but didn’t stop. Instead, it seemed to stimulate her more, and she intensified her efforts.

Given its length, she could only take in half at most, but the occasional feeling of it touching her uvula was truly excellent. He almost wanted to use her horns as ‘handles’ to force it in.

But he had yielded everything to Cecilly for now, and it would be too much for her. For now, he should focus on the service she’s providing…

“Urp.”

“Ugh… N-Noona?”

“Urk- *Slurp.* Urk.”

Contrary to his thoughts, Cecilly was the first to take action. She was taking Issac’s cock deeper than the half she had been swallowing.

At first, it seemed difficult as she took it a bit deeper and then slowly sucked while pulling it out, but as she repeated this process, the shaft gradually began to disappear.

Deeper and deeper. Until the entire large member disappeared into her throat.

Normally, one would gag, but Cecilly was pushing Issac’s large member into her throat with effort. Like diving, she lowered her face to Issac’s groin.

And finally, his large member completely disappeared into Cecilly’s throat. Cecilly’s nose touched Issac’s pubic hair.

Issac let out a rough moan and lifted his head at the unfamiliar pressure applied not by the mouth but only by the throat. It’s commonly referred to as throat pussy in vulgar terms, and he now understood why.

“N-Noona.”

“*Slurp*…. Hmm?”

Cecilly looked up at him with a questioning expression as Issac pushed her face away. But she didn’t remove the cock from her mouth.

Meanwhile, Issac calmed his bursting chest and looked down at Cecilly, then gently grabbed her horn.

“Sorry… I can’t hold back anymore.”

“…?”

At his apology, Cecilly blinked. Just as she was about to pull back, wondering if she should remove it—

*Thrust-*

“Urk?!”

Issac strongly pulled on Cecilly’s horn, using it as a handle. As a result, Issac’s large member completely disappeared beyond Cecilly’s throat.

Cecilly’s body trembled at his sudden impulsive action, but soon she realized what he wanted and relaxed her body, moving her tongue.

As she flicked her tongue, she could vividly feel the member filling her mouth. Issac’s cock, hot and emitting a strong smell.

Delicious. Really delicious. It feels even more so because it belongs to the man she loves.

*Thrust- Thrust- Thrust- Thrust-*

“Urk! Urk! *Slurp! Slurp! Slurp!*”

As Issac moved back and forth holding Cecilly’s horn, Cecilly continuously moved her tongue. Not just moving her tongue, but also tightening her lips to suck strongly, giving a new stimulation.

Without a single gag, Cecilly took Issac’s large member not with her vagina but with her mouth and throat. And leaving almost none of the base out.

Also, emphasizing her innate lewdness, she lowered her hand to finger her dripping pussy. Issac became even more excited by the fact that Cecilly was masturbating while swallowing his member without missing a bit.

*Thrust- Thrust- Thrust-*

“*Slurp! Slurp! Urk! Urk!*”

“N-Noona. Now…!”

Cecilly felt the cock filling her mouth and throat growing larger and harder. This was clearly a signal of ejaculation.

She fingered her pussy more vigorously, anticipating Issac’s essence being released into her mouth. The act of her beloved man ravaging her mouth like masturbation gave Cecilly even greater pleasure.

The member going in and out of her mouth and throat was painful, but strangely it felt good, and her wet intimate part dripped water just by touching it.

“Ugh!”

“Urp!”

*Gulp- Gulp- Gulp-*

Issac pulled Cecilly strongly so that her nose touched his abdomen and released his semen. As he ejaculated in her throat, Cecilly’s body trembled, and she opened her eyes.

When she opened her eyes, her red eyes rolling upward indicated that she had lightly climaxed. In her mouth, her beloved man’s semen flowed down her esophagus, and below, her love juices flowed enough to form a puddle.

With this, it was confirmed that Cecilly, with her lewd and sexy body, had indeed inherited the bloodline of a succubus.

“*Sluuuurp.*”

Cecilly slowly pulled out Issac’s member from her throat, sucking it like candy. Issac still held her horn like a handle.

*Pop-*

Finally, Issac’s large member was completely removed from Cecilly’s mouth. Though it was covered in saliva, it still stood erect without losing its strength.

“Phew…”

Issac, who had ejaculated intensely due to the overwhelming pleasure, exhaled. He had been careless, thinking she was a virgin with no experience.

Cecilly was a demon, and she had inherited the blood of a succubus, plus she was in her mating cycle. She had the specs to easily do what humans couldn’t, and her body was consumed by desire.

The irrumatio just now was part of that. Issac brushed his hair up and looked down.

“*Smooch. Smooch.*”

“…”

“Mmm. *Slurp. Slurp.*”

Still not satisfied, Cecilly was seen kissing or performing fellatio on Issac’s member. She caressed it preciously with her hands while licking it like an ice cream with her mouth.

Thanks to this, he felt his member hardening even more despite having ejaculated once. Issac decided he couldn’t let her continue as she pleased.

He wanted to gift her pleasure, just as she had given him. He gently touched her horn and spoke:

“Noona.”

“*Slurp*… Yes?”

“Shall we go in now?”

At Issac’s suggestion, Cecilly blinked slowly. With his cock standing tall to the sky and her face right next to it, his heart raced even more.

Cecilly held Issac’s member with one hand, seemed to ponder for a moment, and then shook her head.

“Later. I want to taste more now.”

“…Really?”

“Yes. I think I’m getting addicted. Issac’s cock is so delicious. Mmm.”

Cecilly resumed fellatio with words that would drive any man crazy. Issac stroked her head appreciatively, but he felt bad just receiving service.

Shouldn’t he give her the same pleasure? Issac pushed her face slightly, indicating her to stop for a moment.

Cecilly looked up at Issac with a questioning expression as her face was pushed away.

“Noona. Come up on the bed.”

“Why?”

“I have something to do for you.”

Cecilly tilted her head for a moment but moved as Issac wanted. Though consumed by instinct due to her mating cycle, since they were already exploring each other according to those instincts, she obediently followed his words.

Eventually, the two found themselves in the middle of the bed. Even as she moved to the center of the bed, Cecilly didn’t let go of Issac’s cock.

“Turn your buttocks towards my face.”

“Like this?”

Without a hint of embarrassment, Cecilly positioned her buttocks towards his face as Issac wanted. Thanks to this, Issac could closely observe her intimate part.

Unlike Marie’s, hers had a dense growth of black hair. And between them, a wet entrance.

*Drip- Drip-*

She was so wet that her love juices were dripping like water droplets. Issac was in awe, but then he noticed a sensation from below.

“*Slurp. Slurp!* Delicious… *Slurp.*”

Cecilly continued with fellatio without any shame about showing her intimate part to the man she loved. Just looking at this, she seemed to have a much greater lewdness than Marie.

Issac gave a wry smile and then shifted his gaze back to Cecilly’s intimate secret. He used both hands to grab her buttocks and slowly pulled them down.

Finally, when the pink flesh came close to Issac’s mouth, he extended his tongue and lightly licked it.

*Lick-*

“Kyah!”

As soon as he licked her intimate part, Cecilly let out a cute moan and her body trembled greatly.
