Rejuvenation of the Great Chieftain

It was a report compiled from investigations into the small number of human women who enjoyed sexual intercourse with orcs. The document opened with a warning that individual variations might exist. According to the text, the mucus-like fluid secreted from an orc’s penis relaxed the female’s uterus, opening the cervix so the glans could remain inserted during ejaculation.

They could engage in sex for hours without climaxing, only releasing everything at the very end. A single ejaculation was enormous, enough to expand the uterus, and afterward they would expel a sticky clump of mucus to seal the cervical opening and prevent any semen from leaking out. That was how orcs ejaculated.

Hehe. So that was how they achieved such high pregnancy rates. They literally injected the semen straight into the womb and sealed it ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠shut. It was an insemination method designed purely to plant their seed in a female and breed her.

My own uterus was uniquely specialized, allowing me to store semen directly inside. Ordinary human women could never manage it, yet orcs were clearly capable of forcing pregnancy even in them. Their reproductive power had to be extraordinary.

Still, the information claiming they could fuck for hours without ejaculating held true. My body had already climaxed several ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠times, yet Dahgon showed no sign of release. I was thoroughly enjoying the pleasure of his cock pushing past my completely relaxed cervix and ravaging the inside of my womb, so it was fine for now. But given that he had already reached the twilight of an orc’s natural lifespan, I felt a flicker of concern.

“Hoo… hoo…”

He was breathing roughly, having lifted me completely off the ground. Holding my legs, he thrust vigorously while standing. I didn’t want to wound his pride by asking if he was all right, so I secretly channeled a thread of essence to check his condition.

His cock, in direct contact with the magic core inside my uterus, pulsed powerfully and displayed a vigor that completely defied his age. Even his heavy, swinging balls were vigorously producing sperm, radiating essence. Yet while his reproductive organs remained healthy for his years, the rest of his body had aged exactly as expected. It was frail. His muscles in particular were clearly struggling under the continuous exertion; his stamina had declined sharply.

I purified my essence and infused it into him to ease his strain. That was when he suddenly froze.

“Krrk?”

“Aah~ Why did you stop?”

“Strength… suddenly surging.”

“Hehe. Is it because you’re eating me and growing younger?”

“Other females never caused this. Maybe it really is true.”

“Eat plenty and get healthy.”

“Good.”

Smack! Smack!

He resumed his powerful thrusts. I matched the rhythm with my hips and continued refining essence. Though the quantity was large, his essence was turbid and low-quality. I absorbed it, purified it within my magic core into fresh, vibrant essence, and fed it back to him in an endless exchange.

Ugh. Monster essence really did taste unpleasant. Better than goblin, but compared to human essence it was nothing I would willingly consume. Still, as my purified essence—now cleared of turbidity and brimming with restorative power—began circulating through his body, a dramatic transformation I had never witnessed before began to unfold.

Starting with the cock that touched my magic core and received the essence first, his cells revived as though truly becoming young again. The marks of aging simply melted away. The phenomenon closely resembled the rejuvenation drug Grandpa Faust had once researched. That drug had been extremely rare because it required repeatedly concentrating mana stones to create a small quantity of high-purity essence. Yet here Dahgon was, growing younger simply by receiving my purified essence.

I was stunned by the astonishing effect. Apparently I wasn’t the only one.

“Krrrr! Power is exploding! This is the strength I had in my prime!”

“Wow, you really are getting younger.”

I couldn’t see his face from my position, but I watched the wrinkles on the hands gripping my legs gradually disappear, replaced by taut green skin. His previously hunched posture straightened. Vitality surged through his entire body.

I had known that a succubus’s essence governed biological recovery and life force, but Dahgon was the first to display such a dramatic reaction. Could succubus essence simply be highly compatible with monsters? Yet I had never heard of similar results during experiments at Grandpa Faust’s laboratory.

Hmm. Perhaps it was connected to the cycle of consuming his essence, purifying it, and returning it? The lab had used mana stones created from human essence, which might explain the lack of reaction. I wondered whether Kyubey knew about this.

“You have truly made me young again. You are a good female. I will follow you for the rest of my life.”

“Oh my, thank you.”

Until now Dahgon had remained composed, but his voice now trembled with deep emotion. I even felt droplets landing on my shoulder—tears. Seeing the usually pessimistic orc moved to tears made me realize the sense of powerlessness that came with old age had been far heavier than I imagined.

After holding me silently while shedding those tears for a time, he began to thrust again. The stability and power behind each stroke were incomparable to before.

“Krrk. Does it feel good?”

“Yes… a little faster… Yes. Just like that. Hng~”

“I will thrust until the female is fully satisfied. As many times as you desire.”

Enjoying the pleasure of his ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠now-youthful cock plunging in and out of my womb, I continued our union with Dahgon. Only after my internal clock measured more than six hours of continuous sex did his long-restrained cock finally pour semen into me, glans pressed firmly against the depths of my uterus.

Glurk. Glurk.

“Aah, it’s so warm…”

“Krrk… krrk…”

My womb had a lower temperature than a human’s, while Dahgon’s orc semen burned hotter. The contrast filled my entire body with a deep, satisfying warmth. In rear-entry position, his cock buried to the hilt, he breathed raggedly as he continued ejaculating without end. My uterus quickly filled and began to swell.

I stopped Las, who had popped out eagerly to feast on the semen, because I wanted to savor that warmth a little longer. The slime looked dejected for a moment but soon recovered, swimming playfully through the semen filling my womb.

My uterine capacity was roughly twenty milliliters—larger than a normal human woman’s—yet it was nowhere near enough to contain the average five-hundred-milliliter orc ejaculation. Logically it should have been impossible, but the special substances in orc semen apparently induced uterine expansion, allowing it to accommodate everything. The document had been correct.

Dahgon gripped my waist tightly and kept pouring. He had already released more than five hundred milliliters, yet the flow continued. My belly swelled outward, rounding into the same shape I had seen in videos of women who received orc loads. After another ten minutes and roughly four hundred additional milliliters, thicker mucus finally emerged to seal the cervix, concluding the marathon ejaculation.

Boong~

The long plug withdrew from my pussy with a wet sound. I had been holding myself up on my stomach; now I collapsed sideways. The prominently swollen belly rose like a dome.

“Whew. You really let out a lot.”

“Krrk. In my prime it was even greater.”

“Hehe. You look completely young now, don’t you?”

“It is thanks to the female’s grace. I am grateful.”

Dahgon stood tall with perfect posture, exuding a dignity that surpassed any young orc I had seen on the ramparts. His thick arms flexed, and a confident smile played across his face. There was no trace left of the elderly orc from earlier.

He ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠noticed my rounded belly, reached out, and gently stroked it.

“Female. Is your belly all right?”

“Huh? You’re the one who filled it this full, and now you’re asking that?”

“Krrk. Sowing seed is an orc’s instinct. Forgive me.”

“No need to apologize. Having my womb this full of semen feels strangely good.”

My uterus felt like a living pouch dedicated to holding semen. The perverse pleasure sent pleasant thrills through me. While I basked in the languid afterglow of sex, Dahgon—moving with surprising hesitation for his size—carefully climbed onto the bed and lay beside me.

He kept stealing glances, so I finally asked.

“Why do you keep looking at me like that?”

“Is it acceptable for a human female if an orc lies beside her?”

“After everything we just did, you’re worrying about that now? Just relax.”

“As expected, you really are a special female.”

Even as he spoke, he looked secretly pleased. My reaction must have delighted him. We lay side by side on the bed, savoring the lingering warmth of our union, and eventually fell asleep in comfortable silence.

When I woke the next morning, Dahgon had already risen and left. The artificial blood that had slowed during sleep accelerated again, bringing the usual sharp awakening. My vision cleared. I rose from the bed and stretched.

“Ugh! Haa~ Time for me to head out too.”

I retrieved the underwear Dahgon had stripped off and tossed into the corner, then dressed. My lower belly was still noticeably rounded.

“Wow. It’s gone down a little, but there’s still so much. I can feel it sloshing inside.”

The semen trapped by the sticky mucus plug sealing my cervix had been partially absorbed by the inner wall of my latex womb, yet it remained full and shifted with every movement. Over time it had equalized with my body temperature, so the warmth had faded, but the simple knowledge that my womb was full brought an inexplicable sense of satisfaction. I put on my uniform and left the room.

In the living room, Galina sat in a chair fiddling with a communication device.

“What are you doing?”

“Ah, you’re awake? Last night was quite intense, wasn’t it? Hohoho.”

“Ah… you heard everything.”

Her room was on the second floor. I had assumed the closed door would block the sound, but apparently not. There were people who avoided interspecies sex, so I studied her expression. Fortunately I saw no disgust—only a knowing, mischievous look.

“An orc who refused to move for over two long months has finally taken a woman. You must have caught his eye completely.”

“Well… I suppose so. Still, it seems the orcs weren’t completely avoiding women after all.”

“Living together for two months, even monsters start to grow on you. Besides, the only reserves left in the village are women.”

At first they had avoided the orcs out of instinctive revulsion, but after more than eighty days of positive interactions, it was only natural their eyes would turn toward males who radiated such potent masculine energy.

“And orcs are good at sex, of course?”

“Ohoho. If you manage contraception properly, they’re the best partners imaginable. By the way—did you get it all out?”

“Get what out?”

“That huge load that filled your belly, obviously. You used contraception, I assume, but there’s no benefit to holding it inside too long.”

“Ah, I emptied everything, so don’t worry.”

“Cleanup must have been troublesome. You worked hard.”

We chatted a little longer. She told me the location of the inn where Zadyn was staying, and I left the house.

In the village, women moved busily while orcs followed at their heels, helping with every task. At first glance it looked chaotic, but closer observation revealed a clear pattern: one orc per woman, working together as pairs. Some couples even clung to each other openly, exchanging subtle affectionate gestures. The process of coexistence had advanced further than I expected.

I never imagined I’d see orcs and humans living together so peacefully.

Why not? I heard Ryuzan has already accepted orc tribes and they live together.

That’s because they only accepted orcs who converted to Sun God worship. It’s a special case, isn’t it? The people of Ryuzan have extremely unique mindsets—they even acknowledge coexistence with Abaddon.

Just as the people of Ryuzan broke racial barriers through religious values, the women here have broken them through sexual values, right?

Hmm. Since sex is such a major matter for humans, it does seem plausible.

Even the vigor Dahgon displayed while old and frail had been enough to shame most human men. After his rejuvenation, his stamina had become truly monstrous. It was easy to understand how women could become addicted to sex with such orcs.

By the way, did you collect genetic samples from the orc sperm? What’s the result?

Not yet. I’ll do it while we travel later. And could you call him Dahgon from now on?

It seems you’ve taken quite a liking to that particular orc.

He said he would follow me for life. Shouldn’t I show him some attention? Also, about that rejuvenation… As long as I keep purifying essence for him, does that mean his lifespan is effectively infinite?

Did the aging truly disappear at the genetic level?

From what I sensed, yes. He literally became young again.

As long as I—a succubus—existed and continued purifying essence, his lifespan might become infinite like mine. If that was true, then to the orcs the succubus race must be like the legendary elixir.

It seems to have far less effect on humans, though.

Would other monsters experience the same effect?

Probably.

After conversing for a while longer, Elsa withdrew again. I walked through the streets and connected to the network. There had been no contact during the night, so nothing serious should have happened, but I checked just to be sure.
