Chapter 270: Night Sevice 18+ (2)

Isaac and Adelia's passionate night extended into the early hours of the morning, much like other women before them. Consequently, both of them fervently explored each other until the bed was soaked with various secretions.

Adelia, perhaps releasing all the pent-up sexual desire she had accumulated, straddled Isaac and vigorously moved her hips.

Squelch! Squelch! Squelch!

"Ah! More! Keep thrusting! Ah!"

As Adelia vigorously moved her hips up and down, Isaac's penis repeatedly emerged and disappeared. Despite the stark difference from their initial penetration, Isaac eagerly reciprocated with a wry smile.

Somehow, it turned from a service to just ordinary sex, but oddly enough, it was more satisfying. Given Isaac's considerate nature, merely receiving wasn't fulfilling enough for him. He made efforts to ensure the woman experienced pleasure equal to, if not greater than, his own.

Whether this sentiment was conveyed or their bodies simply ignited, Adelia indulged in his love to the fullest.

"Kiss! Kiss me! Mmm! Smooch!"

While others may engage in mutual give and take, Adelia was solely focused on attacking. She even requested Isaac to continue during their breaks, leaving practically no time to rest.

This was the fundamental difference between Adelia and other women. Starting with the basic hardware; there's a difference. While Marie and Cecily would rest in bed if they were fatigued, Adelia begged Isaac to continue, even if it meant sacrificing that time.

When reaching climax, her body would momentarily weaken to the point of immobility, but she quickly recovered and resumed. Although it was somewhat difficult to understand her recovery, she was not a magician but a knight, with practical combat experience.

Perhaps it was a way of replenishing stamina with mana. Isaac silently speculated while vigorously moving his waist.

Squeeze! Throb! Squelch!

"Ah! Oh! Yes! So good!"

Adelia, thoroughly enjoying the dominance, didn't consider descending from Isaac's top. Sometimes they would change positions, but that was when she was on defense; the offense always concluded with her in control.

Occasionally, they would face each other, but even then, Adelia took the lead. She reached climax before Isaac could do anything, so there was no physical strain.

When her throat got dry, she resolved it with the water prepared in advance. However, as the night extended into dawn, even that water was emptied.

'How long will this go on?'

As Isaac pondered, Adelia's body stiffened, trembling slightly. Judging by her jaw dropping, it seemed she had reached climax once again.

Even when Isaac was lying down with an erection, Adelia knew exactly what to do without him needing to give any instructions. But as she became more skilled, the pleasure increased and they found themselves climaxing more often.

Perhaps because of this, Adelia's lower abdomen was noticeably swollen. She couldn't even remember how many times they had climaxed with such force.

Fortunately, there was divine power involved; otherwise, who knows what might have happened. He might have turned into a skeleton.

While Marie and Cecily were giving him time to recharge, Adelia, with her iron-like stamina, didn't even give herself a moment's rest.

"Hah. Hah. Mmm. Ahh. Ugh."

Another thing about Adelia was that once she reached climax, she always had to kiss to ease her passion. Even now, she was passionately kissing Isaac's face while wrapping her arms around him.

As if trying to compensate for the love she didn't receive from her family, Adelia loved kissing more than anything else. Each time they kissed, she trembled with pleasure, reaching a small climax. Yet, despite that, she skillfully moved her hips back and forth, showing that she was fully immersed.

"Whew. Isaac..."

"Yeah, Noona?"

"I love you."

Adelia hugged Isaac with hearts in her sky blue eyes. Isaac also gently moved her waist, taking her into his arms.

If it were any other woman, she would have at least taken out the penis and rested, but Adelia preferred to rest with it inserted. Revealing her desire not to miss a moment, Isaac followed suit without complaint.

Squish, squish...

"Hmm... Ahh... Oh..."

Adelia moaned softly as she moved her hips back and forth. Isaac sucked on her breasts to make her feel more, as Adelia's moans grew louder and the movement of her hips gradually intensified.

Squelch...

"Huh!"

As the glans pressed against the cervix, Adelia's body trembled. Judging by the occasional convulsions, she seemed to be approaching climax, albeit weakly.

Her body had become sensitized through dozens of rounds of intercourse. Even the slightest touch on her sweaty lower abdomen made her tremble.

Amidst all this, with no intention of stopping, Isaac found himself in a dilemma. Glancing outside, he realized it wasn't dawn but morning. Summer, due to its climatic characteristics, saw the sun rise early, yet Adelia was still lively.

Isaac momentarily stopped thinking about when it would end, focusing instead on Adelia as she changed her position. Currently, Adelia had her legs bent as if doing squats, clearly displaying their intertwined genitals.

"Haah. Haah. This... will be the last..."

"The last?"

"Yeah... I'm in pain now... It feels tough..."

As soon as Isaac heard Adelia mention being in pain, he carefully examined her vulva. It was difficult to confirm due to them being connected, but it seemed swollen given that she was in pain.

Indeed, it would be strange if it wasn't swollen considering they hadn't taken proper rest and had been pounding away relentlessly.

Moreover, he couldn't help but think it was remarkable. Even Marie and Cecilia had their stamina depleted before getting swollen, but Adelia was the opposite.

Squish! Squish! Squeak!

"Ah! Ah! Hng!"

Adelia began to move her hips in a squatting position. The swollen area became conspicuous along with moans soaked in pleasure.

Seeing Adelia's flesh shake due to the large phallus... an uncontrollable excitement surged.

Since this was going to be the last time anyway, Isaac lifted his upper body and faced her. And he tightly embraced Adelia.

"Huh? Wh-uh!!"

Before Adelia could even react, their lips collided. As their lips touched, Adelia instinctively stuck out her tongue.

Chup! Slurp! Slurp!

Up top, their tongues intertwined, while down below, their genitals joined together, delivering intense stimulation. Adelia felt a much greater wave of pleasure crashing over her than before, closing her eyes tightly. It wasn't just her; Isaac felt it too.

Before long, the two embraced each other without a word, reaching their final climax.

Squelch! Squelch!

"Ugh!! Uwaaaah!!"

As Adelia's womb, already filled to the brim, was flooded with semen, she reached her peak, stretching her legs forward.

As the semen surged into her vagina, her love juices sprayed out, and her tongue slipped out of her mouth.

"Ugh... Ugh... Ahhh..."

As Adelia's body relaxed back, Isaac carefully withdrew. After lying her down on the bed, he removed the penis he had inserted.

Plop!

"Ah..."

Perhaps due to keeping the insertion for too long, Adelia shivered as she heard the sound of a cork being removed.

Because of the countless releases, Isaac didn't immediately become erect again, unlike the first time. He thought it was over.

Splosh! Splosh! Splosh!

Until he witnessed the sight of the semen that had accumulated in Adelia's womb pouring out like a waterfall.

Her slightly swollen lower abdomen began to gradually deflate as well. It was truly an embarrassing sight.

Feeling his own arousal intensify once again, Isaac slowly approached Adelia. Despite the circumstances, there seemed to be some lingering divine power.

Thud!

"Ah!"

Adelia, who had been focusing solely on her attacks throughout the night and early morning, was almost depleted of energy, surrendering herself to the peak of exhaustion.

However, when Isaac unexpectedly inserted himself, she jerked in surprise, slowly lifting her head.

Gradually, as she met Isaac's gently curved gaze, she realized one thing.

It wasn't over yet. Even if she ended, Isaac didn't.

'Attack' and 'defense' show a clear difference in stamina.

"Ah, Isaac?"

"Sorry, Noona."

Isaac chuckled softly, whispering into Adelia's ear.

"Now it's my turn to attack."

"W-Wait. Ah!"

The exchange of offense and defense continued, and their first night together extended until morning.

******

Isaac and Adelia's affair didn't end until the next morning, not even when it was time for breakfast. Adelia was already satisfied, but due to Isaac's meddling, she almost fainted, enduring until nearly collapsing.

Fortunately, the duration of the contraceptive pill was longer than expected, thankfully sparing Adelia from a longer ordeal that could have almost led to pregnancy. Moreover, since both Marie and Cecily were willing to yield to Adelia for a while, they didn't interfere much. That was the biggest reason their affair could last long.

However, skipping meals was inevitable. Though Anna offered to handle meal delivery herself, Marie wanted to assess the situation first. It might be embarrassing for Anna if she walked in on an awkward situation. It was better for Marie, who had the most involvement with Isaac, to gauge the situation first.

Knock, knock, knock...

"Isaac. It's me. Can I come in?"

Marie knocked on the door, but there was no immediate response. Only a quiet silence returned.

Is he asleep? Marie wondered, tilting her head. Then, Isaac's voice came from inside.

[Y-yes, come in.]

It was a slightly trembling voice, but it must have been her imagination. Without any suspicion, Marie opened the door and entered.

As soon as she opened the door, along with the intense heat, a stimulating smell filled her senses. It circulated throughout the entire room, although she couldn't tell how long it had been lingering.

Suppressing her suddenly racing heart, Marie looked around to find where Isaac was. He wasn't on the roughly made bed, so the only remaining place was...

"Huh? What's this? Where's Adelia-unnie?"

It was a desk. Isaac was sitting at the desk, typing away since the morning. However, Adelia, whom he had spent the first night with, was nowhere to be found. Isaac awkwardly replied.

"She, uh, went to take a shower just now."

"Really? Hmmm..."

Marie narrowed her eyes and glanced sharply at Isaac. His expression was suspicious to anyone who saw it. His lips were trembling, and his expression seemed forced, as if he was trying to hide something. Adelia's absence was also too suspicious.

Chup. Slurp.

(TL: Nah, no wae)

"Huh? What was that sound?"

"What?"

"Didn't you hear a sound just now?"

"I, I don't know."

Suspicious. Too suspicious. Isaac had a truthful personality, but even when he lied, it showed on his face. His demeanor seemed like he was hiding something from everyone. Marie looked at Isaac with a doubtful expression, then shrugged her shoulders.

What could he be hiding? Anyway, she had a different purpose.

"Alright. By the way, what about dinner? When are you going to have dinner?"

"I'll bring it now. Adelia-noona is tired."

"Can she walk?"

"She can."

"Must be because she's a knight. I need to improve my stamina too. Well then, I'll go check."

Marie said that and left the room. Isaac just waved goodbye to her as she left.

And right after that.

"Ugh...! Noona..."

"Mmm. Mmm."

Isaac looked bewildered as he watched Adelia ravish his penis under the desk.

No matter what he said, Adelia was relentless in her oral efforts. With one hand, she traversed the shaft to make sure no part was left unattended.

Even though she was not naked, but dressed neatly in a maid outfit, Isaac was filled with immense excitement.

"Noona!"

"Mmm..."

Slurp! Slurp! Slurp!

As the signal of climax approached, Isaac grabbed her head and released coolly. Adelia didn't turn away despite the thick semen pouring into her mouth.

As Isaac relaxed his grip on Adelia's face, she slowly withdrew the penis from her mouth. She didn't forget to suck strongly enough to make her cheeks hollow in.

Slurp!

Finally, Isaac's large object came out of Adelia's mouth. While Isaac gasped at the sight, Adelia closed her eyes and savored the semen in her mouth.

Gulp~

After swallowing the semen in her mouth, Adelia opened her mouth. As if to prove she had finished it all, her mouth was impeccably clean.

Isaac looked at Adelia, who was lasciviously licking her lips, with a complicated expression. This was another action Adelia did on her own, calling it "midnight service".

Hiding under the desk to perform a service on her lord's penis was a situation Isaac was experiencing for the first time.

"How was my service, my lord?"

Adelia grabbed the limp penis with one hand and licked the shaft with her tongue. Not a dignified knight, but a slave completely immersed in servitude and pleasure.

Isaac smirked at the sight and gently stroked her head. What did it matter if she was a pervert or a knight?

"It was excellent."

Now she was his woman.

At Isaac's praise, Adelia smiled happily, kissed him on the cheek, and her kissing made the penis rise again.

"Then until the meal arrives..."

The service of the personal maid continued.

"I'll serve you ♡"

It didn't stop even into the morning.
