Mother-in-Law Before the Wives
The preparations for our first night moved faster than I'd expected.
Barely two hours after the evening banquet ended, they summoned me.
The walk there, though, took forever. I passed through corridor after corridor of ornate doors and lavish decorations before a sliding door finally appeared.
The two women standing guard looked me over with subtle, knowing eyes, then announced my arrival.
"Palace Master. The Imperial Son-in-Law has arrived."
"...Let him enter."
A quiet voice drifted out from within.
"Please go in. And... do well."
I gave a quick nod and stepped through the open door.
Soft lantern light filled a vast chamber that felt more like a grand reception hall. At the seat of honor sat a beautiful woman.
Gone was the overwhelming majesty she had radiated in the great banquet hall. In its place was a pure, almost delicate air—like a woman waiting for her wedding night.
She must have fully restrained her power long before I arrived.
"Sit."
For someone who had been practically bouncing with anticipation earlier, her tone had turned remarkably composed. Not that I was about to call her on it. I carefully took a seat.
Bing Seolhwa poured tea and offered it to me. It carried a complex floral fragrance.
"I will say it again—this is only because of your physical peculiarities. There is no other choice. If you misunderstand and the Goddess grows angry... well. I alone can take responsibility for that."
Your tongue is getting long, Palace Master... I swallowed the retort and asked something that had been bothering me instead.
"Hmm. That feels a little different from what I heard earlier."
"What does?"
"You said that when a man arrives, everyone opens their doors to welcome him. Are you the exception, Palace Master?"
"Th-that is only for the sake of producing heirs! I... I can no longer bear children..."
I tilted my head.
I had no idea how old she had been when she gave birth to her daughters, but the Palace Master's appearance—no matter how generously I looked—was late twenties at most. Not "well-maintained" or "youthful for her age." Simply that age.
Which meant she had undergone something like Hwangoltaltae, a full body reconstruction... but did that not restore the womb as well?
Before I could voice the thought, Bing Seolhwa's face flushed scarlet and she shouted.
"I-I know what you are thinking, but it is not that! It is because I am far too strong! No one alive today can impregnate me, and even if someone somehow managed it, no child could take root inside me!"
"I-I had guessed as much..."
I scrambled to cover myself. Bing Seolhwa shot me a sidelong glance and took a sip of her tea.
In other words, the seed of an ordinary man could never pierce Bing Seolhwa's egg, and even if some peerless master succeeded in fertilizing it, that fragile little embryo would never implant in her womb and draw nourishment.
Put another way... she had double-layered natural contraception. And against a scrub like me, it was a hundred-percent guarantee.
Which meant I could creampie her as much as I wanted without a single worry?
"Jackpot."
"Jack... what? What did you just say?"
"Ah—I meant the tea smells excellent."
I hastily raised my cup. Bing Seolhwa nodded.
"It is called Choyacha. A traditional tea of the North Sea Ice Palace, drunk before the first night. It eases tension and warms the body to make conception easier. Though for us it holds little meaning..."
Choyacha, huh. Pretty intense name. Not that I cared. All I wanted was to get to the bedroom already; I had no intention of leisurely sipping tea.
Come on. She had just flirted with me by saying I could dump loads inside her with zero consequences. She started it.
I downed the lukewarm tea—already cooling in the chill air—in one go. Bing Seolhwa stared at me in flustered surprise.
I seized her hand and pulled her to her feet.
Honestly, after spending the entire banquet surrounded by beautiful women, their beauty and scent had already set my body on fire.
I was ready to explode with or without this damn tea.
"Ah. W-wait a moment. A little more conversation..."
"We can talk after."
"There are important matters concerning my daughters as well..."
"I should hear those from the parties involved. It's only polite."
"This is hardly polite either..."
I roughly slid open the door to the bedchamber.
A faint fragrance filled the room; only a single tiny lantern burned.
The bed was absurdly large for one person—big enough for four grown men to lie side by side with room to spare.
Is this thing designed with mother-daughter threesomes in mind?
The moment that idle thought crossed my mind, the voice of the Goddess—whose face I was already beginning to forget—echoed through my head.
Now, I'll teach you everything about sex. First comes the kiss of foreplay.
I yanked the still-chattering Bing Seolhwa into my arms and locked eyes with her.
She fell silent and drew a sharp breath.
I smiled faintly. The instant she opened her mouth again, I covered it with mine.
"Mmph!"
The scent of the tea from moments ago flooded my senses, followed by the soft press of her lips and tongue.
My tongue slipped into the gap and coiled around hers.
"Hnnph!"
I swept every corner of her mouth, sucking her saliva while pouring mine into her, thoroughly mixing our fluids.
At first her hands had stiffly pushed against my chest; now the strength drained from them.
She was a supreme master who could erase someone like me with a casual flick of her fingers. Her resistance was pure embarrassment, nothing more.
One hand cradled the nape of her neck; the other stroked down her back and waist, descending slowly.
Her hands, which had been against my chest, soon slid up to wrap around my neck in answer.
I guided her step by step toward the bed.
By the time we reached it, Bing Seolhwa was panting, kissing me as if craving my saliva.
There was a reason for that.
A gift for you. I'll share a little of my breath. Your exhalations and scent will always arouse the opposite sex.
The Goddess had breathed into my open mouth.
Second gift. I'll share a little of my bodily fluids. Yours will become an aphrodisiac that paralyzes reason.
She had let sweet saliva flow into my mouth.
Third gift. I'll baptize your cock. It will always erect into the shape that brings your partner the most intense pleasure.
She had spread her legs wide and pulled me in. As I entered the Goddess, her juices coated my cock thickly.
And the final gift. I'll teach you sex itself. Before your cock, any woman in the world will become nothing more than a helpless bitch and collapse.
In short, my current body was... the ultimate anti-female weapon.
I shoved Bing Seolhwa onto the bed.
"Haa—. Haa—."
She stared blankly, flushed, at the tent straining my pants. She even swallowed hard without realizing it.

"Do as the Palace Master wishes."
At my words she glanced up at me. That was the look of someone clinging to her last shred of reason.
So I reached out and stroked her earlobe.
"Nnh!"
She trembled and caught my hand. I reversed the grip and pressed her palm against the front of my pants.
Her hand shook violently. But it never left.
I had no intention of helping further.
Biting her lip, Bing Seolhwa looked up at me with a resentful glare, then slowly raised her hands and undid the knot of my trousers.
Those trembling fingers looked exactly like a woman facing her true first night. Impossible to believe she had two grown daughters.
When my cock sprang free, Bing Seolhwa sucked in a sharp breath. Her pupils went empty for an instant before snapping back into focus.
The thick scent of precum and groin must have swept through her mind like a storm.
I wanted to snap that final thread of reason, but if I did, the internal and external energy she had restrained would explode.
"Going crazy?"
"...Y-yes. The Goddess did not send you for nothing."
Breathing roughly, Bing Seolhwa nodded in a hurry. She no longer had the composure to salvage her pride.
I felt a twinge of regret, but I pushed her back down.
I would have loved to make her suck me off, but if she swallowed even a little precum she would lose her mind completely and we would never get to the main event.
"Keep your head clear."
I don't want my cock turned into ground meat...
The moment she nodded, I flipped up her skirt. Her legs twitched shut, then the strength left them and they fell open of their own accord.
Watching a beauty of this caliber spread her own legs for me was more satisfying than I expected.
"Th-the lantern..."
"No."
I refused to fuck a woman this gorgeous in the dark.
Through the fully raised skirt, Bing Seolhwa's undergarments were, of course, already soaked through.
I roughly pulled them aside.
The pussy faintly lit by the lantern was neater than I expected.
Pink, tightly closed—looking as if she had never had sex, let alone given birth.
Well, the silver bush was a little thick, but that was no flaw.
I dragged my index finger up the slit from bottom to top. The folds parted and love juices spilled out in a thick trail.
"Haahng!"
Bing Seolhwa arched her back like a drawn bow and shuddered.
Praying she would stay conscious, I pressed my cock against the entrance.
Her pussy twitched as if eagerly awaiting the invasion.
"Palace Master. Keep your head clear."
With those words I thrust my hips forward. After a faint resistance at the entrance, just as the head was almost fully inside, something blocked me.
I froze for a second. What? It couldn't be a hymen... some kind of barrier?
Bing Seolhwa clutched my shoulders, panting, and whispered.
"Haa, haa. Push through. I-it is only because of Hwangoltaltae that I am like a virgin again. I have restrained my external energy, so even you should be able to break it."
The eyes looking up at me held firm resolve.
Honestly... I was glad this woman was my first. With anyone else I might never have gotten started. Or I might have been devoured by a woman who lost her mind before I even entered her.
I gave the woman beneath me a light kiss and forced my cock deeper.
"Kh-hup!"
A short scream burst between our joined lips, and something tore with a series of soft snaps.
Once the head fully entered her vagina, her pussy wrapped around me with astonishing softness and pulled me in.
I broke the kiss and looked down. A woman with faint tears in her eyes gazed up at me. Her upper garments had come almost completely undone, half her breasts already bare.
What a thrilling sight.
I fully opened her top and freed those full breasts. Soft rather than firm, beautifully shaped mounds spilled free as if flowing into my hands.
"Y-you don't have to—!"
"Of course I do."
Leave tits this big covered? That would make me no man at all.
I pushed my hips the rest of the way, burying myself to the root, and filled my hands with her heavy breasts at the same time.
"Ahn! Haaung!"
Bing Seolhwa rolled her hips to receive me. Her entire body was the embodiment of softness.
Inside, her pussy cradled my cock in a warm, snug embrace; her breasts felt like sinking my hands into soft cream. Their size made my palms disappear completely.
I pressed our groins flush together and caught my breath for a moment. My cock and Bing Seolhwa's pussy twitched, molding to each other's ideal shape.
The twitching soon settled.
"Then... I'm moving."
I didn't wait for permission. I started thrusting at once. Even if she had refused, I would have begun—I couldn't hold back any longer.
Long, deep strokes began, pulling almost all the way out before slamming back in.
"Haang! Auk! Hnn!"
Every time the flared ridge of my cockhead scraped the length of her vaginal walls, her hips jerked.
Apparently Bing Seolhwa's climax was centered on her G-spot.
I immediately lifted her waist into an arch, adjusted the angle, and sped up.
"Th-that...! Too...! Aaahn!"
Under the intensified stimulation she clawed at the bedding and gasped.
Her walls clamped down as if desperate not to let me go.
I lowered my head to the massive breasts swaying like waves.
The moment I took one plump pink nipple into my mouth and rolled it, Bing Seolhwa's neck snapped back.
"A-ah, no! Hhk! The stimulation... is too strong! Ahn! Khhnn!"
She pounded my shoulders with her fists. But my brain was already under the complete control of my cock.
I obeyed its orders, sucking her nipple even harder while driving my hips home.
"Ook! Ooohk! Ooooh!"
Bing Seolhwa, who had been fighting to stay conscious, began letting out animalistic moans.
"Ook! St...stop! Ooohk! I really can't...! Wh-why won't my body...! Ughk! Ooooooh!"
She seemed to be desperately trying to push me away, yet no strength entered her limbs. Her eyes finally rolled back.
At the same instant I felt something burst from her deepest point—like a dam shattering and water flooding free.
Sssshhhhh!
A fierce jet of fluid shot against my lower belly.
That alone would have been fine...
But from Bing Seolhwa's lower abdomen, the vast internal energy she had been restraining also erupted.
It was a force on the scale of a natural disaster—like an avalanche of ten-thousand-year snow collapsing.
I felt the urge to cum from the crushing pressure of her walls even as I sensed my own doom approaching.
They say a man ruins his life because of his dick...
Looks like I'm about to become the living proof.
With that thought I came in an explosive orgasm and threw my head back.
They say the human brain feels the most intense pleasure right before death.
The climax of ejaculation hit so hard I nearly blacked out from it alone.
The moment I finished pumping, the landslide of her internal energy swallowed me whole, and I lost consciousness and collapsed.
