Chapter 168: Morning in Helion(1)[R-18]

The long night stretched on until the break of dawn. When Isaac had his first time with Marie, they had finished by the early hours of ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the morning, but Cecile was a demon. Her basic physical capabilities were on a different level.

Furthermore, unlike Marie, who was an ordinary human, Cecile had undergone extensive training, including yoga, giving her extraordinary stamina. The rough calluses on her palms were a testament to her dedication.

Of course, that was the story when she was just a normal demon; in Cecile's case, things were a bit different.

First, her "evil cycle" had arrived, a period where her pent-up desires demanded release, causing her bodily sensitivity to skyrocket. This was evident from how she reached a climax just by taking Isaac’s member into her mouth.

Second was the succubus blood flowing through her veins. The blood of a succubus, which had been dormant for over a hundred years, had finally manifested, though its concentration was quite thin.

If it had been even slightly stronger, she might have been able to harvest Isaac’s essence more easily. However, because the blood had thinned over generations, it ended up only heightening Isaac’s arousal further, leading to the "messy" encounter Cecile had craved.

With both conditions met, Cecile’s entire body had essentially become an erogenous zone. No matter how great her physical stamina was, it meant nothing once her mental fortitude was exhausted.

It was only as dawn approached that Isaac realized Mora’s divine power was actually a gift for Cecile’s sake—to help her endure him.

"Slurp... Mmm. Is this okay?"

"Roll your tongue a bit more. Yeah, like that."

"Chup... Slurp."

The morning sun had already risen, but the man and woman were still engrossed in sex, having foregone sleep entirely.

Cecile had Isaac’s member sandwiched between her large breasts and was diligently sucking on the protruding glans. Even though Cecile’s breasts were far above average in size, they couldn't quite hide the entirety of Isaac’s length.

Isaac lay back on the bed, leisurely enjoying the service Cecile provided. With the shaft buried between her soft breasts and only the glans being stimulated, he felt like he could go at any moment.

The position known as paizuri required both the man and the woman to be above average in size. Since Marie was a well-fed noblewoman, her breasts were on the larger side, so they used this position often.

However, Cecile’s breasts weren't just above average; they were top-tier. While the glans remained exposed, the breasts completely enveloped the shaft, providing a fresh and intense sensation.

Moreover, unlike Marie’s breasts, which were soft like marshmallows, Cecile’s were firm and elastic. The difference in texture naturally led to a different kind of stimulation.

The night of pleasure that began late in the evening showed no signs of ending even as morning came.

Is this also thanks to the divine power?

Isaac thought to himself as he watched Cecile caress the glans peeking out from her cleavage. Even if he had undergone knight training, his stamina shouldn't be this high.

Though they had taken breaks whenever Cecile fainted, it made no sense that he didn't feel even a hint of fatigue.

Surely, the divine power Mora had granted him was producing some kind of effect. Since it also helped Cecile replenish her energy, it was a win-win for both of them.

Slide—

"Slurp... Chup. Hehe."

When Isaac gently stroked her horns, Cecile pulled her mouth away from his glans and giggled. She used both hands to move her breasts up and down, squeezing the shaft buried in the valley between them.

Her skin was incredibly soft, so there was no chafing, and thanks to her frequent ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠use of saliva, it felt just as good as her vagina. Isaac stroked Cecile’s horns with a warm gaze before moving his hand down to her chest.

Then, he pinched her still-erect nipple and gave it a sharp tug.

"Kyah!"

As Isaac pulled on her nipple, Cecile let out a lust-filled moan. Even this minor pain translated into pleasure for her.

Isaac continued to pinch and pull at Cecile’s delectable nipples, helping her become even more aroused.

"What are you doing? Keep sucking."

"Mng... Haa... Slurp. Chup. Mmm."

At Isaac’s mischievous command, Cecile took his glans back into her mouth. She moved her breasts with her hands while pleasuring the rest with her mouth.

Even then, Isaac didn't stop tugging at her breasts. Through the sex that had lasted until dawn, he had discovered one thing: Cecile had masochistic tendencies.

Whether he slapped her buttocks firmly or pinched her nipples like this, Cecile only let out moans of pleasure, never cries of pain.

Isaac didn't particularly have sadistic leanings, but seeing the Princess of Helium—a woman revered by all demons—disheveled and drowning in pleasure made it hard to hold back.

Seeing as her horns have turned back to black, this must be her true preference.

Isaac checked her horns while teasing her breasts. Just last night, they had been flushed deep red, but now they were entirely black.

This indicated that Cecile had fully satisfied her pent-up desires. It made sense, considering she had reached double-digit climaxes throughout the early morning.

This meant that the Cecile he was seeing now, with her desires sated, was her true self. In truth, she wasn't much different from how she acted during her evil cycle.

"Noona. I'm going to finish now."

"Mng... Hurry and give it to me. I want to eat Isaac’s cum. Lick."

When Isaac gave the signal, Cecile pulled her mouth away and flicked her tongue. Seeing her act as if she were about to enjoy a delicious candy, Isaac could no longer hold back and erupted.

Spurt! Spurt!

"Kyah...♡"

Since he had released several times already, the volume and thickness were somewhat diminished, but it was more than enough to coat Cecile’s face.

Cecile let out a coquettish sound as her lover’s semen splattered across her face.

As the white fluid smeared over her skin, she wiped it away with her hand and put it in her mouth.

"Slurp. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠It’s delicious. Lick. I want more."

"Hmm."

While Cecile savored the semen on her face, Isaac turned his head toward the window.

Even though the sun rose late in winter, dawn had fully broken, signaling the start of a new day. He had spent the entire night exploring Cecile’s body, yet thanks to Mora’s divine power, he felt full of energy.

However, both he and Cecile felt it would be a shame to end it just like this. They needed something special to mark the finale.

"Noona."

"Yes? What is it?"

"You said you do yoga, right?"

"What’s yoga?"

Cecile asked back, holding his penis, which had gone limp immediately after ejaculation. Seeing her ask such an innocent question while holding his member made the blood rush back down there.

"Ah! It’s standing up again. Nom!"

As Isaac’s member regained its strength and stood tall, she took it into her mouth as if she had been waiting for the moment. Isaac gave a wry smile at her greed, which was bordering on addiction.

He was slightly worried she might not be able to function in daily life at this rate. He gently pushed the head of the woman who was obsessed with the member sandwiched between her breasts.

Cecile pulled away as he pushed her head back, looking puzzled.

"Listen to me until I'm finished. Yoga—I mean, you said you do stretching, right? I heard from Mr. Gartz. That demons do high-difficulty stretching."

"Yes, that’s right."

"Then, can you do what I want?"

"I’ll do anything Isaac wants. In exchange, this is mine. Chu♡"

What a lewd woman. Isaac almost lost his reason when Cecile answered sexily while kissing his glans, but he managed to suppress it.

He had heard that once the evil cycle ended, desire would fade quickly, but it seemed he had flipped a switch. He could clearly see a future where he stayed in Helium for the entire vacation doing nothing but having messy sex.

But life had to go on. Isaac pondered how to stop Cecile’s rampage and came up with a good plan.

"Let’s make a bet. It’s related to the stretching I mentioned."

"What kind of bet?"

"If you can hold the pose I want for five minutes, you can do whatever you want with this for the rest of the day."

Isaac said, pointing to his member, which had already regained its vigor and was pointing toward the ceiling. At the suggestion that she could handle his penis however she liked all day, Cecile’s red eyes sparkled.

If one looked closely, they almost seemed to have heart shapes in them; she was clearly hooked. As Cecile gazed at him lovingly while stroking his member, Isaac laid out the condition.

"However, if you can't hold it, we stop here for today. I want to keep going too, but I’m worried about what others will think."

"Don't worry about that. I already told Mom. I told her we might not come out until this evening."

"You ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠might be fine since you're a demon, but I'm human. I need to eat. And I need to visit the temple as well."

"Mng... Okay."

Cecile, who had been flicking his member with her finger in disappointment, suddenly tilted her head as a question occurred to her.

"Come to think of it, strangely enough, I’m not hungry. In fact, I feel full."

"Didn't you say you have succubus blood? Maybe it’s related to that?"

"Is it? Well, according to the records, succubi use a man’s essence as food. I guess I won't ever starve as long as I'm with Isaac."

"Instead, I’ll be the one shriveling up."

After a brief, silly joke, the two of them got off the bed and stood up. Unlike Marie, who was an ordinary person, Cecile was a trained demon, so she was able to stand despite it being her first time.

Even the pain of her lost virginity had long since been eclipsed by pleasure. All that remained was the sticky residue of lust.

Now that it was morning, Isaac admired Cecile’s naked body, which was much clearer than before. Her breasts, slim waist, and hips were magnificent no matter how many times he saw them. Even a drawing couldn't depict her this perfectly.

Also, as evidence of the intense intercourse from the night before, various fluids had dried around her pubic area. Semen, vaginal fluid, saliva, and even virginal blood.

She could have removed it all with cleansing magic, but Cecile didn't bother. She figured it would just get dirty again anyway, so why waste the mana?

The sight of this woman with such a lewd body, who spoke so shamelessly while mating like an animal, made his lower half throb.

Cecile smiled wickedly when she saw him harden and began to caress him. She slid her palm up his shaft, then gripped it gently, moving her hand up and down.

"To think Marie was the only one enjoying something this good... I’m starting to feel a bit resentful. You’re staying in Helium for the whole vacation, right?"

"I am, so shall we try the stretching now?"

"Yes. What do you want?"

"Well..."

Isaac explained the pose he wanted, and Cecile listened quietly before acting without hesitation.

First, she extended one of her long legs high into the air and held it firmly with one hand. Since she wasn't wearing any clothes, her private area was exposed quite vividly.

However, Cecile didn't seem to feel any shame as she asked Isaac with an innocent face.

"Like this?"

"...You’re incredibly flexible."

"This is the basic of basics."

Regardless of Cecile’s answer, Isaac closely examined the pose she had taken. The position she was in was commonly known as the "I-line balance" or a standing split.

It was a pose that only those with extreme flexibility could achieve, and it was easy to feel shame because the genitals were so clearly exposed. But Cecile had long since cast such shame aside.

Isaac swallowed hard and slowly approached her. His member was already as hard as it could get.

"Are we doing it like this?"

"Yeah. If you endure for five minutes, it’s your victory."

"Hmph. I’m used to this now... Hyah!"

Schluck—

Isaac took advantage of Cecile’s overconfidence and inserted immediately. Caught off guard by the sudden thrust, Cecile almost lost her balance, but she narrowly managed to recover.

"If you lose your pose, you lose the bet. Got it?"

"Th-that’s cheating... How could you... Ugh!"

When Cecile protested while trembling, Isaac answered by thrusting his hips. Her vaginal fluids flowed down, wetting the floor.

Unlike the positions they had used so far, this one felt like it was piercing deep inside. Moreover, they had only done it on the bed until now; this was the first time they were doing it while standing on two legs.

As unexpected challenges arose, Cecile looked at Isaac with trembling eyes. He was wearing his characteristic gentle smile.

"I’m starting."

"Wa-wait... Ahh!"

Squish— Squish— Squeltch—

As Isaac began to move his hips in earnest, Cecile let out a cry. As the thick member filling her moved back and forth, the amount of fluid being secreted increased.

Cecile felt the strength leaving her waist, but she gritted her teeth and endured. If she could just hold out for five minutes, she could have Isaac’s member all to herself.

"Ugh. Nng! Hah! Haa!"

She even held back her moans to maintain the I-line balance, but she failed to predict that this would only heighten Isaac’s arousal.

It felt as if he were taking her by force, so Isaac moved his hips even faster and harder, ravaging Cecile’s vagina to his heart's content.

With every thrust, fluids splattered everywhere—some running down her legs, others dripping like raindrops. After about a minute of intensely indulging in Cecile’s body...

Squish— Squeltch— Squish—

"Hyah! Ah! Ahhh!!"

Ultimately unable to withstand the fresh stimulation, Cecile let go of the arm that was holding her leg. The leg she had held straight in an I-shape dropped and came to rest on Isaac’s shoulder.

Cecile had been defeated by pleasure in less than a minute. The realization that this would be their last session for the day flashed through her mind, but she didn't care.

Right now, she just wanted to focus on feeling Isaac’s member filling her inside. There would be plenty of time during the vacation anyway.

"It hasn't even been a minute and you're already done? Aren't you a bit too easy?"

"Mng... No... Ahh. Isaac is... Isaac is just too... Hng!"

Despite the awkward position, Cecile maintained her balance on one leg and accepted Isaac’s member deep inside.

Unlike when they were on the bed, the member stimulated her upward, and occasionally the glans would hit her cervix. They had tried various positions from last night until morning, but this new one provided a brand new sensation.

"Up we go."

"Kyah!"

Isaac changed positions while continuing to thrust inside her. He lowered the leg that was on his shoulder and lifted her up.

Startled, Cecile naturally wrapped both her legs around Isaac’s waist. With Isaac holding her and Cecile clinging to him, the member delved even deeper.

"Ugh...!"

"I feel something being pushed back."

"Hng... You’re so mean. Really..."

Even before, only a small part of the base was left outside, but now that he had pushed it all the way in, she could vividly feel her cervix being pushed aside.

This position, known as "lift-and-carry," was difficult unless the man had significant strength, but Isaac’s body had once undergone knight training. Furthermore, he had grown rapidly over the past few months, and his strength had increased significantly.

Cecile was also on the lighter side since she was a demon, not a beastkin. Although she was heavier than Marie due to her height and breasts, it wasn't difficult at all.

"I’m going to move now."

"Mwah. Chu. Slurp. Chup."

As he spoke, Isaac began a deep kiss with Cecile. Cecile also used her arms and legs to wrap tightly around Isaac and accepted his tongue.

Finally, Isaac moved his hips with practiced ease, and Cecile trembled as the member penetrated deeper than in any other position they had tried.

Slap— Slap— Slap— Slap—

"Hyah! It’s too! De-deep! Ahh!"

Every time the glans collided with her cervix, Cecile let out a frantic moan. The strength in the arms and legs wrapped around Isaac’s body tightened, and her fluids flowed as if a faucet had been turned on.

Isaac held Cecile and thrust into her with all his might. Since she had asked him to make a mess of her, he intended to keep that promise until the end.

Even as her cervix was pushed up by the glans, even as Cecile let out unique moans at the sensation, and even as the strength left the limbs wrapped around him...

Isaac didn't stop his hips, determined to give Cecile the ultimate pleasure until the very end.

Splat— Slap— Squish— Squeltch—

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

Cecile began using formal speech as she stuck her tongue out. It was her signal that she was about to reach her limit.

Isaac felt that he was also close to ejaculating, so he captured Cecile’s mouth. As Isaac kissed her forcefully, Cecile moved her tongue and savored him greedily.

Slap-slap-slap-slap—

"Mmph! Chup! Slurp! Chup! Mwah!"

With her upper mouth, she accepted her lover’s tongue, and with her lower mouth, she accepted her lover’s member.

Being attacked from both above and below, she quickly approached her limit. Before long, Cecile pulled her mouth away and cried out as if screaming.

"Hyaaaaah! I’m going! I’m going, Isaac-nim! Kyaaaaah!!"

"Ugh...!"

Thump!

As if those words were the trigger, Isaac thrust his hips all the way. Because he pushed in without leaving even a bit of the base, her cervix was shoved upward.

Spurt— Spurt— Gush— Gush—

"Aaaaaahhh!!"

At the sensation of the semen seeping past her cervix and into her womb, Cecile let out a scream of peak climax. Her body trembled intermittently, and the legs wrapped around Isaac’s body tightened.

Her arms were the same; unable to withstand the climax, she scratched his back with her fingernails, leaving marks. However, in the afterglow of his own ejaculation, Isaac didn't feel even a hint of the sting.

Drip— Drip— Splat—

A moment later, a mixture of vaginal fluid and semen began to drip from Cecile’s entrance onto the floor.

The floor already had a puddle from the fluids Cecile had released. The fluids of the two lovers dripped onto it as if marking the spot.

Isaac took a ragged breath and checked on Cecile. She was merely trembling from the climax, unable to even lift her head.

Hug—

"Haah..."

As he pulled his member out of her, a sound like a cork being popped was heard. Simultaneously, semen and vaginal fluid spilled out from inside her.

Isaac carried Cecile just as she was and moved to the bed. He laid her down and looked into her face.

Cecile was catching her breath, her face flushed deep red. Isaac gave a loving smile and stroked her horns.

"Noona."

"...Yes."

"I love you. Truly."

The confession of love was followed by a deep, lingering kiss. This time, it was a short but intense kiss to confirm each other's feelings.

After kissing Isaac, Cecile gave a happy smile, stroked his face, and spoke softly.

"I love you too."

With the lovers' confessions, the first night that had lasted until morning finally came to an end.

"Master...♡"

"... ..."

It seemed the night might last a little longer after all.
