Fine, what if there were subordinate relationships I was not aware of?

To begin with, I was the one keeping secrets in that regard, so was there really a need to pry sensitively into someone else’s secrets?

‘It is what it is.’

Just as I was about to casually move on,

“Sein-ah—!”

Mr. Ryu Jinyong cried out his daughter’s name in a trembling voice.

“…?”

Confused, I looked around to find Ryu Sein collapsed on the ground.

Her face was pale, and cold sweat was profusely breaking out from her entire body. It seemed like she was in a pretty severe condition.

What was going on?

I was the one who defeated the mermaid monster, and Ryu Sein hadn’t come near it since she released her Qi blast.

Could she have been injured while fighting the mutated zombies?

No, there were no visible external injuries…

Mr. Ryu Jinyong muttered shakily.

“De, Deviation… Why all of a sudden…?”

To that question, one of the swordsmanship trio, Instructor Seo Inho, answered.

“When the guild master went toward the mermaid monster earlier, Sein tried to use her sword qi again. I tried to stop her, but she ignored me, and I couldn’t intervene…”

“Sword qi again? What a fool…!”

Deviation.

I had read about it in Wuxia novels.

It was a symptom where a martial artist’s internal energy went berserk during Qi circulation (similar to meditation), usually triggered by an external shock.

However, since Ryu Sein was not in the process of Qi circulation, the likelihood that this “Deviation” was different from what I knew was high.

Firstly, she seems to be in pain, so…

“Ciel, use Grace of Light on all 11 of us.”

I cast a group healing spell, hoping it would also recover any damage caused by radiation exposure.

“Yes, Master.”

Flutter—

Ciel closed her eyes and spread her wings wide. Soon after, pure white feathers emitted dazzling light, enveloping us all.

“Huh?”

“Wow…!”

Exclamations burst out.

The [Grace of Light] Ciel used always warmed both body and soul.

I felt as if many invisible wounds scattered around my body were being gently healed.

“…Thank you.”

“Thank you!”

Gratitude towards Ciel poured out, but only for a moment.

“No… her condition isn’t improving…!”

Full of despair, Mr. Ryu Jinyong’s voice dampened the atmosphere once more.

I stepped forward and asked,

“What exactly is Sein’s condition right now? Please explain in detail; maybe we can help.”

Mr. Ryu explained hurriedly what he knew.

He said that Deviation was more likely to occur when one tried to forcibly use up energy while it was already depleted.

In mild cases of Deviation, a few days of rest could result in recovery, but in severe cases, it could be life-threatening.

Currently, Ryu Sein was in a very severe state of Deviation, unlike anything he had seen before.

“Some have recovered from this condition, but some have also died in their beds… If something happens to Sein, I…”

“……”

Amidst the silence and gloomy faces, Ciel took a step forward.

“May I take a look?”

“Ciel? Of course!”

Since she looked entirely like an angel in appearance (and, in fact, she was a real angel), Ryu Jinyong promptly handed Ryu Sein over to Ciel.

Ciel placed her hand on Ryu Sein’s lower abdomen, closed her eyes, and stayed that way for a few seconds.

After a moment, Ciel opened her eyes and came over to me, whispering in my ear.

“Master, it seems like a unique manifestation of simple mana depletion. Infusing her with mana should improve her condition.”

I whispered back.

“Oh, really? How do we infuse mana?”

“It’s simple. She needs to absorb your semen.”

“Ah…”

Right, the effect of my special attribute [Wand of Emission].

I had forgotten about that.

.

My special attribute allowed me to discharge mana through ejaculation.

Thanks to that, my semen became a nutrient-rich mana elixir, eliminating the need for contraception and giving it a sweet scent and taste rather than its usual musky smell.

However, there was one limitation: the mana could only take effect when directly ejaculated into the recipient.

Because of this, I had to scrap the plan of tricking Baek Jihun into consuming a ‘nutrient porridge’ made of my semen to awaken him.

But now…

Ryu Sein has fallen into Deviation due to mana depletion.

To infuse mana, I had to ejaculate directly into her body.

“What a situation to be in…”

The only silver lining was that it didn’t necessarily have to be injected into the uterus. While the effectiveness diminished in comparison, I had already confirmed several times that the mana could be absorbed effectively when consumed orally. I had found this out through both Serena and Ciel.

“Let’s get this over with quickly,” I said, pulling down my pants.

“Serena, Ciel, undress.”

“Yes, Master.”

They replied in unison.

The current location was the dormitory of the Haneul Nuclear Plant, temporarily designated as Ryu Sein’s sick room. As soon as Ciel said, “Master can cure Ryu Sein,” Ryu Jinyong grabbed onto my pants. I laid down the condition that no one else could be present during the treatment and sent everyone away.

And so, we were now here.

Two beds were in the room, side by side. Ryu Sein lay on the one beside us, her face pale. The three of us planned to have sex on the other.

The plan was simple.

I would bring myself close to ejaculation through Serena and Ciel. At the last moment, I would ejaculate into Ryu Sein’s mouth.

If Ciel’s diagnosis was correct, then Ryu Sein would recover from her Deviation once she absorbed the mana from my semen.

Upon hearing my command, Serena and Ciel quickly disrobed.

I didn’t usually indulge in threesomes, so I had never really compared the two side-by-side like this. The differences were noticeable.

Both were amply endowed in the chest department.

However, Serena’s breasts were slightly more voluptuous, whereas Ciel’s overall physique was slimmer, revealing the outline of her ribcage beneath her pale white skin.

Serena’s soft, supple body made a good cushion and provided a comforting touch.

Ciel’s body, as white as fresh snow, would show red marks whenever she was embraced, fulfilling a certain sense of conquest and making her ideal for the ‘first snow play.’

Deciding who was superior between them was a difficult question since they both had their uses…

“Ughh….”

Just then, Ryu Sein, who had been unconscious and lying on the bed next to us, let out a groan.

I had gotten momentarily distracted by the attractive chests of Serena and Ciel, which I saw every day but always found tempting. This was not the time; I had to quickly bring myself close to ejaculation for Ryu Sein’s sake.

“Both of you, present yourselves.”

“Yes, Master!”

“Sure.”

Serena energetically spread her legs wide to form an ‘M’ while Ciel turned around, got on all fours, and arched her back, presenting her buttocks.

Ciel looked back over her shoulder at me while presenting her rear. Her vaginal area was already quite wet, with fluid running down her legs.

Serena, who usually wouldn’t get wet so quickly, had only a couple of drops of fluid flowing down between her legs at this point.

“Ciel, how did you get so wet so quickly?”

“Ever since I thought you looked cool in the fissure, I’ve been like this…”

She’d been like this since the fissure?

Ciel’s voice had a shy but seductive tone that instantly energized me.

“Ciel, you’re amazing…”

Even Serena couldn’t help but marvel at the state of Ciel’s drenched area.

Given the urgent situation, it was important to get things moving. I grasped Ciel’s hips and, without any warning, thrust into her.

The sound of wetness followed; her body was perfectly prepared, allowing for a smooth, frictionless penetration.

“Huuuuuuuh—♡”

Buzz.

Just like a smartphone vibrating to indicate it’s beginning to charge, Ciel trembled slightly at the insertion.

I thrust my hips rapidly.

Squish, squish, squish, squish-♡

Her juices permeated between the shaft and the vaginal flesh, creating lascivious squelching sounds as they met in rapid friction.

This was not the first time I had to bring myself to climax quickly in a pressing situation. I had done so in the past, having sex in the middle of the road with Ciel when Jeongbalsan Station’s department store was in crisis.

At that time, the tension was so high that I couldn’t maintain an erection.

But this time was different.

I now knew well that panicking would only lower my arousal. To climax quickly, even knowing that there was a patient next to me waiting for my semen, I had to enjoy the sex.

Keeping that in mind, I admired the pink flesh inside Ciel’s clinging vaginal walls. When I thrust into her, the view was just of her white labia, transforming as if into a gigantic peach-shaped rice cake. When I pulled out, that lascivious flesh seemed to chase after me, begging me not to go.

“Hnn…♡, Hm♡, Hm♡, Hoooh…♡, Heeeeeeuh—♡”

Ciel came quickly in the midst of this speed-focused sex.

Plop-♡, Sploosh-♡

Not even a minute had passed since we started.

As I was relishing the feel of Ciel’s trembling inner flesh, my eyes caught Serena, who was quietly watching from the side.

‘Ah.’

I realized that I didn’t have to focus solely on Ciel for this.

Since there were two of them, if I enjoyed both, I would reach climax twice as quickly!

This was absolutely necessary for Ryu Sein’s rapid recovery.

“Serena. Look at me and come over, Ciel.”

“Yes!”

Serena moved closer, carefully avoiding Ciel’s outspread wings, and bent her head down near my buttocks.

Then, as if she had been waiting for this moment, she began to suck on my nipples.

“Sllluuurp… Suck, Slurp…♡”

“Ah……”

Unintentionally, a small moan escaped my lips, causing my penis to twitch.

In truth, I had intended to suck on Serena’s nipples while having sex with Ciel, but this wasn’t bad either.

I started to thrust my hips again, while caressing Serena’s blonde hair as she clung to my nipples like a baby.

Squish, squish, squish, squish-♡

“Huuuuuuh…♡, Hah…♡, Uh♡, Huh♡, Uh♡”

Whoomph-

Ciel, who was clutching the bedsheet as if it were some precious treasure, suddenly fluttered her wings.

“Suck, sllluuurp…, nip, nip…♡”

Serena continued passionately, rolling her tongue.

I felt like I could climax soon as well.
