Ch.167Deep Night of Helium (2)

The position commonly known as the 69 position was something Issac and Marie had done many times before. Surprisingly, it was Issac who first suggested it, as this position wasn’t widely known.

It’s a position where a woman presents her genitals and anus before her lover’s face. Marie was embarrassed at first, but after getting used to it, she came to enjoy it. Besides this, their sexual compatibility was so good that they were trying various other positions as well.

However, this position requires thorough cleaning beforehand, as it could produce an unpleasant odor otherwise.

Lick-

“Kyaah!”

Cecilly trembled violently and showed an intense reaction when Issac lightly licked her vagina with his tongue. Her hands, which were holding his member, momentarily tightened.

The stimulation was completely different from when she had masturbated earlier. It felt like electricity coursing through her brain. Though she had already discarded her shame, having the man she loved lick her private parts was a huge stimulus for Cecilly.

She hesitated at the unfamiliar pleasure, but only briefly. After regulating her breathing, she licked the thing in front of her. She lovingly caressed it with both hands and savored it sweetly like candy with her tongue and mouth.

Lick-

“Heung!”

“Mmm. Slurp. Slurp.”

“Hnnng! Hnnk!”

But as Issac began licking her private parts with his tongue, she could barely maintain her caresses, let alone control her body. She felt a tingling sensation in her lower abdomen and fluid gushing out.

Her legs were losing strength to the point where she wanted to surrender her body. Even the patience she had cultivated to fight her inner evil was meaningless.

This wasn’t about inner evil—it was “pleasure” given by her beloved. In over a hundred years, this was the first time someone other than herself had done this with their mouth.

‘It tastes slightly sweet.’

While Cecilly buried her face in Issac’s groin and felt the foreplay, Issac licked and savored her private parts. The taste and smell of a woman’s fluids vary depending on what she eats.

If Marie’s fluids were salty and tangy like lemon, Cecilly’s had a fruity, sweet flavor.

Having grown up as a princess of Helium, she must have eaten various foods, but the sweetness might largely be due to her nature. She had sucked his member like ice cream, saying it was delicious, so it was a convincing hypothesis.

Issac closed his eyes and indulged in Cecilly’s fluids. Rather than dripping like water droplets, they flowed continuously like an open faucet, quickly making the area around his mouth slick.

“Slurp- Slurp- Slurp-“

“Haak! Haang! Ahng!”

Cecilly now only moaned, seemingly having lost the energy to suck his member. He could continue licking her private parts until she reached climax, but Issac was an experienced lover through countless encounters with Marie.

He knew that a woman’s climax doesn’t burst all at once like a man’s, but builds gradually like climbing stairs before erupting at the limit. However, unlike men who experience a “sage time” afterward, women’s climaxes last much longer.

So when Cecilly stopped fellatio, he would stop too, and when she regained her senses and took his member in her mouth again, he would lick her private parts.

Though he hadn’t specifically requested it, by now Cecilly must have realized: if she didn’t pleasure Issac’s member, this pleasure would disappear forever.

“Uguk! Uuk! Slurp! Slurp!”

As soon as Cecilly realized this, she closed her eyes tightly and took Issac’s large member deep into her throat. She moved her head back and forth like diving, even without him forcing her by holding her horns.

Simultaneously, Issac concentrated on exploring her pink private parts. Not just with his mouth—he also caressed her buttocks as if handling fragile glass. Her peach-shaped buttocks were addictively pleasant to touch.

Squelch-

“Uguub!”

Soon, when it seemed she had become accustomed to licking with her mouth, Issac spread the entrance of her vagina wide with his thumb and pushed his tongue inside. Cecilly’s eyes widened and her body stiffened as Issac’s tongue entered her vagina.

She could clearly feel the softness of his tongue inside, unlike the hard sensation of fingers. It was a completely different dimension from when she had masturbated earlier.

Cecilly held Issac’s member deep in her throat and clenched her fists. The tingling sensation rising from below passed through her lower abdomen, up her spine, and penetrated her brain.

This was dangerous. But she couldn’t stop.

As she stared wide-eyed, waiting for Issac’s signal to release…

Tuk-

“Uuub! Puha! Huaaang!!”

She exploded violently as soon as Issac touched her protruding clitoris with his hand.

Squirt! Squirt! Squirt!

“Haaaah! Haang! Uaang! Aang!”

Cecilly screamed with pleasure each time he touched her clitoris. Fluid erupted from her private parts like a fountain, soaking Issac’s face.

However, Issac didn’t mind and kept his tongue inside her vaginal entrance. Rather, he drank her fluids as if receiving holy water and rubbed her clitoris with his index and middle fingers.

Like a dam bursting, Cecilly trembled intermittently as she reached climax. The climax given by someone else—especially the man she loved—was on a completely different level from masturbation.

“Huuu… Hung… Hauu…”

Cecilly buried her face in Issac’s groin and regulated her breathing. Her jet-black hair flowed down like a curtain, and her deep red eyes lost focus.

Yet she still firmly gripped his member with her hand, briefly revealing Cecilly’s lewdness. Even with her mind in chaos from the climax, she still licked his shaft.

Issac liked Cecilly’s lustfulness, which was no less than—perhaps even greater than—Marie’s. He felt thirsty, as they hadn’t even started the main act yet.

He carefully moved Cecilly’s buttocks to the side. Even as he moved her legs onto the bed, Cecilly showed no intention of removing her face from his member.

“Noona. I know you want to suck, but we need to stop now.”

“No… I want to eat more… You haven’t cum yet… Slurp.”

Cecilly kept seeking Issac’s member even in her dazed state. Perhaps because she was a demon, her recovery power was no joke.

Marie couldn’t move from climax to insertion, but Cecilly seemed fine. Issac smiled wryly and then gently dissuaded her.

“I’ll feed you plenty later, so stop for now.”

“Hiing…”

When Issac sternly reprimanded her, Cecilly reluctantly separated from his member. She looked dejected, but her gaze remained fixed on Issac’s groin.

Swoosh-

Then Issac grabbed Cecilly’s slender shoulders and made her body spin around. Cecilly turned her head and faced Issac.

She blinked a couple of times at his golden eyes that shone brightly even in the darkness, then smiled broadly. She then pursed her lips, demanding a kiss.

Although his member had already been in and out of her mouth, Issac fulfilled her request without hesitation. After all, any fluids would have gone down her throat to her stomach, and he had no reservations about what his beloved woman wanted.

Moreover, Cecilly’s mouth emitted a sweet fragrance—the same unique fruity scent from her fluids.

Just as she had compared herself to a dessert, Cecilly’s body was indeed a sweet fruit dessert.

“Slurp. Slurp. Slurp. Haaa…”

Cecilly collapsed backward while kissing Issac. She felt the softness of the bed against her head.

Issac laid Cecilly on the bed and continued kissing her for a while before silently separating his lips. A silver thread of saliva stretched between them before breaking weakly.

Eventually, he looked at Cecilly lying on the bed. Her large breasts, with excellent elasticity, maintained their round shape despite her lying down, and the lines of her waist and pelvis were truly artistic.

Add to this her intimate area, soaking wet with fluids. Issac swallowed hard and then placed his member on Cecilly’s stomach with a thud.

“Wow…”

Cecilly marveled at the size of his member, which almost reached her navel. Would that really enter her? What would it feel like if it did?

Would she feel pleasure even more intense than before? She pressed his member firmly against her stomach with an expectant expression.

When Issac’s member touched her toned abdomen, she could properly feel the sensation. As she had thought all along, it was hot and hard like an iron rod heated in fire, just as Marie had described.

‘Marie… said she couldn’t take it all, right?’

Could she really accept all of that? Being taller than Marie and having a more developed pelvis, perhaps it was possible.

Cecilly lovingly caressed Issac’s member and then looked up. Issac was smiling gently, as if waiting for permission.

“…Issac.”

“Yes, noona.”

“I love you. So…”

Squelch-

Cecilly confessed her love in a trembling voice and then spread the entrance of her vagina wide with both hands. Fluid that had been staying inside her vagina gushed out.

Then she smiled as if soaked in desire and desperately pleaded with Issac. Her red eyes glowed more bewitchingly.

“Please… ravage me completely. Lord Issac.”

“… …”

“You can handle me however you want. You can be rough. So please… put your member in.”

This alone was enough to make Issac’s member throb, but…

“My body and heart are all… yours, Lord Issac♡”

The decisive blow that followed made Issac take a deep breath and spring into action. Normally he would need to caress her, but with the flood already there, no preparation was necessary.

Eventually, he grabbed his member with one hand and began searching for the entrance to her vagina. Being experienced, finding the entrance was easy.

Finally, the glans touched her vagina, and Cecilly gripped the bedsheet tightly, preparing for the pleasure to come. Her heart was pounding, and her breathing quickened.

“…Noona.”

“Yes, yes. Tell me.”

“You’re really a pervert.”

With those words, Issac smiled slightly and…

Thrust!

Without a moment’s hesitation, he pushed his member inside.

“Ugk…!”

As Issac’s member filled her inside, Cecilly’s tongue slipped out of her mouth. Her waist arched like a bow, and her hands gripping the bedsheet tightened.

There was some pain because he entered forcefully rather than slowly, but it became meaningless due to the wave of pleasure that followed.

It felt like a hard, fiery rod filling her entire lower abdomen. Cecilly trembled and then looked down with difficulty.

Most of that huge member had disappeared. She smiled happily at the fact that she was connected as one with the man she loved and shifted her gaze.

Issac was also looking down at her with his characteristic deep smile.

“Ah, Lord Issac…”

“Yes, noona.”

“I love you… really… I love you…”

Cecilly spread her arms and confessed her love once more. Issac lowered his upper body and embraced her as she wanted.

As their bodies overlapped, Cecilly’s enormous breasts were pleasantly squashed. Issac appreciated the sensation of her excellent breasts as well as the feeling of her vaginal walls.

It was natural for her to be tight as a virgin, but there was also a feeling of soft envelopment. The thick fluids that had been secreted acted as a kind of gel, creating a different sensation from Marie.

Most surprisingly, Cecilly had accepted most of Issac’s large member. A little of the base remained outside, but there was no feeling of the glans touching the cervix.

This gave Issac a new stimulation. He stroked Cecilly’s face and quietly asked:

“Does it hurt?”

“It just feels good… so please move…”

“Okay. I understand. Chu.”

Issac kissed Cecilly lightly and then raised his upper body slightly. Instead of pulling back, he moved slightly forward.

Kyung-

“Kyahit!”

The remaining base disappeared completely, and the glans hit the cervix. Cecilly felt as if electricity was flowing through her entire body at that sensation.

Squelch-

“Unng…”

Afterward, as Issac pulled his hips back, the member that had filled her inside disappeared. Cecilly moaned hotly as the rod scraped various parts of her vaginal walls while retreating, but she also felt emptiness.

It was natural to feel empty when something that had filled every space disappeared. Finally, just as the glans was about to be pulled out…

Thrust!!

“Huaang!!”

Issac thrust his hips strongly and re-entered. The glans hit the cervix once more, and Cecilly screamed with pleasure.

Squelch-

“Huung…”

Slowly pulling out.

Thrust!!

“Aaang!!”

Strongly inserting again.

Squelch-

“Aung…”

Once more, slowly pulling out.

Thrust!!

“Huuuk!!”

And again, thrusting in strongly.

This was a process for her to get accustomed, and each time Cecilly let out screaming moans. She had completely adapted to Issac’s member and was only receiving pleasure.

Issac moved slowly and then glanced down. Proving she was a virgin, blood was mixed with the gushing fluids.

But Cecilly, perhaps due to her nature, already had a body that seemed experienced. It seemed fine to proceed as he usually did with Marie.

Normally, he would go slowly and considerately, but Cecilly didn’t seem to need that. Still, he wanted to make her feel climax.

Grasp!

“Unng…!”

Issac raised his upper body completely and grabbed each of Cecilly’s breasts with his hands. His hands were buried in the massive mounds.

Then he played with her full breasts as he pleased while moving his hips gently. He touched or pulled the pink nipples that stood erect.

He began to treat her roughly to make her a mess, as she had wanted.

Thrust! Thrust! Thrust! Squelch!

“Huaang! Aang! Ang! Kyaang!!”

Cecilly continuously moaned as her breasts were toyed with and his hips moved. Due to the excessive fluids, squelching sounds began to emerge.

Issac firmly grasped Cecilly’s large breasts as handles and indulged earnestly. Based on his sex with Marie, he included not just simple repetition but also control of intensity.

If Cecilly seemed about to climax, he would deliberately move slowly, and if she calmed down a bit, he would thrust strongly.

Unlike the simple, vigorous movement of Marie’s first night, he was incorporating technique to give Cecilly extreme pleasure.

Splash! Splash! Splash!

“Huah! Unng! Slurp. Slurp. Slurp! Hua…”

He also kissed her occasionally so her mouth wouldn’t be bored. When Issac explored her mouth, Cecilly responded. Not only that, but she wrapped her legs around Issac’s waist to stimulate him more.

While their tongues intertwined like mating snakes, Issac continued to thrust into Cecilly’s vagina relentlessly. Her mouth was being toyed with through kisses, her breasts with his hands, and her lower mouth with Issac’s member.

The three elements harmonized exquisitely, bringing her closer to the limit. Tears formed at the corners of Cecilly’s eyes, and her vaginal walls contracted strongly.

Issac noticed that climax was approaching and examined her face. Her red eyes were starting to roll upward, revealing the whites.

Then all that remained was to release everything. He maintained the kiss and moved his hands, which had been grasping her breasts, downward.

When he reached her lower parts, already soaking wet with fluids, he touched the clitoris he had identified earlier with a tap.

“Huuk!!”

Cecilly’s body jerked as he touched her clitoris. Like before, it felt as if electricity from her vagina was traveling up her spine and striking her brain.

But that wasn’t the end. Issac strongly tensed his sphincter muscles to make his member even harder, then roughly thrust while stimulating her clitoris with his hand.

Splash! Splash! Squelch! Thrust!

“Uaang!! Aang!! Huah! Haang!! Kyaang!”

Cecilly was now almost writhing and screaming. Something rising from below, through her lower abdomen, up her spine, and penetrating her brain told her that climax was imminent.

Issac pulled his hips back and then suddenly thrust upward strongly.

Kyung!

“Kyaaaang!!”

Cecilly finally reached climax as the glans and cervix collided. Her waist arched like a bow, and the bedsheet crumpled under her strong grip.

Squirt! Squirt! Squirt!

“Haaaah! Haang! Uaang! Aang!”

While her long, slender legs that had been wrapped around Issac’s waist trembled, fluid erupted like a fountain from her vagina, which was still penetrated.

It was a much larger amount than when she had climaxed orally, enough to soak the bedsheet thoroughly.

Cecilly had finally reached orgasm.

“Hung…! Haa…! Uung…”

Squelch-

“Hih!?”

But the issue was Issac. While Cecilly was catching her breath, Issac was slowly moving his hips.

Only then did she realize: Issac hadn’t ejaculated yet.

The true main event was just beginning.

Issac gently stroked the cheek of Cecilly, who seemed to be trembling with fear, as they faced each other. Already maintaining high sexual excitement due to her orgasm, Cecilly flinched when he caressed her cheek.

A woman’s orgasm is not easy to achieve, but once reached, it also descends slowly. So currently, Cecilly’s lewd body was in its most sensitive state.

It was suitable for continuously feeling pleasure as if her brain was melting.

“You said it, right? To make you a complete mess.”

“Ah, Issac…”

Cecilly called Issac’s name in a trembling voice. Issac lovingly stroked her cheek and then put his finger in her mouth.

A few months ago, when they were alone in a cafe, Cecilly had sucked his finger first. But now, Issac directly inserted it into her mouth.

Cecilly sucked on Issac’s finger, which had a sweet scent from her fluids, while facing him. His member inside her vagina was still maintaining its firmness and strength.

“Aum… Slurp… Ua…”

Splash!

“Ugub!”

She opened her eyes wide when Issac thrust his hips once. However, her mouth was blocked by Issac’s finger, so she couldn’t even make a moaning sound.

Splash! Splash! Squelch! Thrust!

“Hih! Uuk! Aeu! Uang!!”

Issac began moving back and forth again while violating Cecilly’s mouth with his finger. Now, water splashed in all directions with each insertion.

Already sensitized to the extreme by her climax, Cecilly detected her climax rising again. Not only the insertion but even the violation of her mouth felt like pleasure, as did the squeezing of her breasts.

Would she really die like this? A demon’s recovery power is meaningful for physical strength or wounds, not for such climaxes. Rather, the succubus blood seemed to prevent the once-reached climax from easily subsiding.

Moreover, with the evil cycle overlapping, her current state after reaching orgasm was such that her entire body was like an erogenous zone.

“Huang. Aung. Lord Issac…”

“What is it, noona?”

“I’m sorry. I’m sorry, so…”

Cecilly apologized, not having expected the stimulation to be this strong. However, Issac snorted and retorted:

“Then why are you smiling?”

“Ehe… No…”

Though she denied it, Cecilly was wearing a happy smile. Her eyes were already glazed over, indicating that she clearly wanted more despite her words.

Issac removed his finger from Cecilly’s mouth and decided to change positions. First, he temporarily withdrew his member from her vagina and then flipped her body over.

Due to the relentless pleasure, Cecilly’s face was pressed against the bed, lacking the strength to get up.

Then Issac stroked her peach-shaped buttocks before insertion and, with a devilish smile, extended his hands—not to her waist, but toward Cecilly’s horns.

He grabbed the horns like handles and forcibly lifted her. As Issac forcibly raised her by the horns, Cecilly, despite her dazed state, supported her upper body with her arms.

Splash!!

“Huaaang!!”

Issac inserted his member into Cecilly’s vagina without any warning. As the pleasure that penetrated her brain was transmitted again, Cecilly moaned.

This position allowed deeper penetration and properly stimulated the erogenous zones inside the vagina, bringing greater pleasure.

Splash! Splash! Splash! Splash!

“Uhng! Ahng! Aaang! Huang!”

While Cecilly gasped with pleasure, Issac admired her from behind. The erector spinae muscles extending in a straight line down the center, the thin waist line, and the peach-shaped buttocks below.

The sight of those large breasts bouncing with each thrust was truly spectacular.

‘I should release once first.’

Thanks to Mora’s divine power, his erection was lasting a long time, except for the irrumatio. However, he couldn’t keep it pent up, so it seemed good to ejaculate once.

Above all, one of the reasons Mora gave him divine power was to transfer it to Cecilly. The method of transferring energy through sex had existed since ancient times.

Issac was about to make a final spurt when he suddenly noticed the luscious buttocks. Plump and seemingly very spankable buttocks.

Since she had asked to be made a mess anyway, he wore an expression tinged with sadism. One hand was enough to hold the horns.

Then Issac raised his arm high and…

Slap!

“Kyaang!!”

He strongly struck Cecilly’s peach-shaped buttocks. As soon as he spanked her, Cecilly let out a scream mixed with moans.

At the same time, he felt her vaginal walls tighten much more strongly. Issac, unable to contain his excitement, continued to spank her buttocks.

Slap! Slap! Slap!

“Uang! Aang!! Uhng!!”

Each time he spanked her buttocks, Cecilly let out screams soaked in pleasure. Her vagina also repeated contraction and relaxation.

From this, Issac learned one thing: proving her request to be ravaged completely, Cecilly enjoyed being tormented.

She was not the princess of demons but a lewd body no different from a succubus itself.

Splash! Splash! Splash! Slap!

“Haang! Lord Issac! Lord Issac!! I, I…”

Cecilly cried out, calling Issac’s name. Her tongue coming out indicated that another climax was approaching.

Issac also felt the signal of ejaculation, so he temporarily stopped spanking and moved his hips. Then, instead of the horns, he firmly grasped her buttocks and pulled his hips back long for the finale before thrusting vigorously.

Splash!!

“Huaaaang!!!”

Cecilly reached her third climax with her tongue sticking out.

Gulp- Gulp- Gulp-

Issac also released his seeds deep into Cecilly’s womb. Although it was his second ejaculation, the amount was by no means small; rather, it had increased.

Having ejaculated inside Cecilly instead of Marie, Issac exhaled the breath he had been holding and looked down. Her buttocks were red, and Cecilly’s body was trembling.

Could a first night be this pleasurable? He slowly withdrew his member and spanked Cecilly’s buttocks refreshingly.

Slap!

“Haung…”

She trembled at the spanking, still feeling the climax. Issac looked at his member, which was still standing tall despite having ejaculated twice.

It was still insufficient. With what he had steadily accumulated and the divine power received from Mora, it couldn’t be helped.

The night was still long. Issac approached Cecilly, who was trembling with her face buried in the bed.

“Noona. Can you do more?”

“Yes… I can do more…”

She seemed to have quickly recovered her strength, though she had seemed about to faint just moments ago. Perhaps as a succubus, her strength recovered more with each ejaculation she received.

If not that, then perhaps the divine power Issac received from Mora had transferred to Cecilly. Maybe the dangerous person wasn’t Issac but Cecilly.

Issac felt elated at having conquered Cecilly, who was much stronger than him and even designated as the next Demon King, and extended his member.

Cecilly raised her trembling body when the huge member was presented right in front of her face.

“I’ll help you.”

“What? Uub!”

Without further discussion, Issac grabbed Cecilly’s horns and began irrumatio. Cecilly’s eyes widened at the member that filled her mouth, and then she trembled.

Squirt-

The clear sound of fluid eruption from below. Issac moved the horns up and down.

“Ugub! Uuk! Slurp! Slurp! Uguk!”

Tonight, there was no respected Princess of Helium. Only one lewd woman remained.

“Aah… I’m going to cum again.”

“Slurp! In my mouth… cum in my mouth…”

Splurt- Splurt-

Issac ejaculated in Cecilly’s mouth and enjoyed the long night.

“It’s delicious… More… Give me more…”

“As you wish.”

“Kyaang!”

Cecilly also had an unforgettable first night.
