Mistake
The carriages of House Bayorn were reserved for nobility alone; no common soul would dare so much as peer inside. That was why mother and son found themselves alone together—and why the Viscountess’s isolation was complete.
No matter how tightly Darin squeezed her eyes shut and tried to let the hours pass in feigned ignorance, the limit was clear. The man’s gaze, wordlessly tracing every contour of her face and the front of her body, was far too blatant to ignore.
When it grew unbearable, she had no choice but to abandon the pretense of sleep and shudder.
—Rustle.
Darin quietly sat up. Her son had long since seen through the act; further performance would be meaningless.
“Have you finished your little play?”
His voice was laced with amusement, pleasant enough to the ear—yet the moment she groped for the meaning behind the words, her lips went rigid.
Kael only made a mistake.
Even after being raped by her own son, the mother still could not come to her senses. Or rather, she still could not accept it—that was the more accurate phrasing.
He’s twenty-three, yes, but he’s still only a child who hasn’t left his mother’s arms.
Darin denied the reality of the monster her son had become. No matter how anyone else might look at him, this man with his powerful body was, to her, nothing more than her child.
Affection for his mother had simply been accompanied by lust, and he had expressed that love a little too roughly. He still had immature sides; if she soothed him, those rough edges would surely smooth out in time.
This was an accident. Yes… just an accident…
The mother made her decision. She would dismiss the sin of incest as a single night’s mistake. If only she kept her mouth shut afterward, no harm would come to her son, and she herself would have nothing to be ashamed of before others. Darin knew it was not right—yet from where she stood, there was no other choice she could make.
Kael was still young.
Blinded by lust, he had simply made a mistake with his mother.
Who knew? Three years of campaigning against the Demon King might have left him with some mental illness.
“Kael, I understand. Yes… it could have been a mistake.”
The unbearably gentle mother wanted to overlook her son’s error. Yet Kael only tapped his knee with a finger, content to admire the soft shape of her lips.
“It’s all right. You’re still young. There will be times when you can’t restrain your impulses.”
The way those neat little lips pressed and shifted with every word she spoke was almost coquettish. If he pushed his cock between them, wouldn’t he taste a sticky paradise?
—Slick, stroke.
The man’s fingers trailed stickily along the woman’s thigh. He preferred to speak with this beautiful girl through the body rather than words.
“I don’t understand what you’re talking about.”
The girl strained with all her strength to shove away the wrist stroking her thigh, then forced herself to continue.
“W-what do you mean, you don’t understand? It’s exactly what I said. From today on, please—come to your senses.”
“Looking at you, Mother, it seems you still treat me like a child.”
“…Isn’t that only natural?”
Darin barely managed to suppress the despair that had begun to seethe in one corner of her heart. The fact that she had coupled with the very child she still treated as a child filled her with revulsion.
“What happened the other day… yes, we can just let it pass as an ugly nightmare from a single moment.”
“…An ugly nightmare?”
“……”
Had her true feelings slipped out? Without realizing it, she had spoken words thick with naked disgust. Those words also contained her fury at herself for having mixed bodies with her own son.
But the son listening to them seemed more than merely hurt.
“How can you speak of your son’s first experience that way?”
“…I-I should be the one saying that. How could you do such a thing to your mother?”
Darin stole glances at him even as she trembled with injustice. Even now, riding in the carriage, the traces of incest still clinging somewhere on her body seemed to crawl over every inch of her.
The mother was seized by the urge to throttle her own throat, yet the son who had wounded her remained utterly composed. What was so hurtful about this that he had to wear such a pained expression?
“I’m disappointed. You chewed on your son’s cock so deliciously, and now you turn around and act as if it disgusts you.”
“Kael! Please just shut that mouth of yours—your mother is one breath away from exploding!”
“Hmm. It’s a pity our thoughts differ so much. For me, that single night was so satisfying I never want to forget it…”
“I told you to shut up—! And your mother is not your woman! Why on earth do you keep talking like that?!”
The reason Darin could barely sustain even this short exchange, veins standing out on her neck, was obvious. Every time her son toyed with her, she wanted to scream in horror.
The mother was rotting from the inside because of a son who insisted on treating her as a lover rather than a parent.
And the son simply began to watch, in silence, the parent who was gasping in torment.
“……”
Silence arrived without warning. Those vivid blue eyes slowly traced the woman’s body. What was he thinking?
His expressionless face made it impossible to predict what he might do next, and the mother’s body shrank in on itself. Regret followed as well. She should have kept pretending to sleep. But that blatant stare had made even that impossible.
“……Hahaha!”
The man’s eyes curved as he looked at the trembling girl. So that was it. He understood more or less. The reason Mother was suffering was that she had not yet become his woman.
“It seems I misjudged. When hearts are at odds, conversation isn’t always necessary.”
“…What are you talking about?”
The man rose abruptly inside the spacious carriage and roughly tested the door latch with thick fingers. It looked as though he were checking just how securely the carriage door was locked.
“First, I’d like to clear up a misunderstanding.”
“A misunderstanding…?”
After that incomprehensible behavior, he suddenly said something like that. Still, Darin felt a small flicker of relief that he was speaking at all. If her son offered an excuse, she had fully intended to pretend to yield, understand him, and forgive the transgression.
“The misunderstanding that the night I spent with Mother was a mistake.”
“…Ah.”
Unfortunately, the woman realized at once that her expectations had been wrong. Not only because of those words, but because she saw the lust filling the eyes of the man who had just confirmed that the carriage entrance was locked rock-solid.
“Mother.”
His voice was bright, almost sunny. Darin squeezed her eyes shut, covered both ears, and shook her head, yet the devil’s voice filled the interior of the carriage and dragged the woman down into the abyss.
“When a man and woman who have already mixed bodies find themselves alone in a sealed room… isn’t it obvious what comes next?”
Kael slowly stroked his mother’s cheek. She seemed far too tense; he only meant to ease it. There was the more forceful method of yanking her chin up, but that would have been too disrespectful for a son to do.
“The reason you’re suffering, Mother, is that you still haven’t accepted me.”
The cunning devil tapped at the woman’s heart. If she wanted to escape the sea of despair even a little, she should hurry and fall.
“Your son will help you.”
—Rustle.
Darin had no choice but to feel every brush of her own son’s hands as he peeled away her dress. First he knelt, then the shoes, next the shoulders, then the lining itself…
She forced strength into her trembling jaw and fought the urge to die. When her eyes suddenly flew open and met her son’s, nausea surged up at once.
Yet that did nothing to stop Kael’s hands as they stripped the woman bare.
—Thud, thud, thump.
The girl who had barely conquered her terror struck her son’s face with both hands and kicking feet. Darin was forced to taste, all at once, the guilt of striking her own child with her own hands and the helplessness of knowing such resistance was useless.
—Thud…
In the end, realizing that even this was more wretched than simply staying still…
“Hic… huuk…”
…she could only freeze in place, shedding tears like a child.
“…K-Kael, please stop. You can just call it Mother’s mistake instead of yours. All right? I-I won’t even resent you after this. I’ll erase it from my head. We only have to keep our mouths shut.”
Even while facing the woman’s tear-streaked face, Kael shook his head without mercy.
If he let it go the way Mother asked, returning to daily life would not be difficult. But they had already mixed bodies, and Mother had glimpsed his true nature; going back to a clean mother-and-son relationship as before was impossible.
“What can be restored is only the surface. You’ll still love me, Mother, but you’ll feel distance and revulsion. And I’ll wither away, unable to satisfy my desire for you.”
“B-but, Kael…”
“There can be no middle ground for a mother and son who have already spent a night together.”
“……”
Faced with that despairing truth, Darin wore an expression full of loathing—yet she could not deny it. Nothing her son said was wrong.
“Aaaah…”
Her vision seemed to go dark; even her ears felt as though they were failing. She could not accept it. She could not accept that the everyday life she had shared with the son she cherished and loved most had been stolen—nor that the one who had stolen it was that very son.
Tears streamed down, wetting the corners of her eyes. Her moist lips opened and closed soundlessly, unable to form a single word. Watching her, the son’s cock stiffened hard. The filthy urge to shove it between those lips had been rising for a long time already.
Those lips she used to speak words or eat food—if she would only suck his cock with them, it would be wonderful.
I’m going mad.
Even knowing she was suffering, the pitiful, feminine way she looked made the urge to pin her down surge violently. Though it had only been recently, he already missed, with aching clarity, the sight of this woman pinned beneath him, sobbing and crying out.
Kael realized it by instinct. If he did not soothe the barbarian lust right now, he would treat Mother even more roughly.
During the campaign, whenever the madness for Mother rose, he had barely managed to vent it by cleaving demon heads in two with his axe.
But since setting foot on the peaceful soil of Bayorn, there had been no such opportunity—so he had no choice but to take it out on the person herself.
There was no aphrodisiac either; if he forced a rough coupling, her delicate flesh was likely to be hurt. Yet grabbing Mother’s hair and shoving his cockhead at her was also something a son could not do. As always, unlike his father, he had no intention of taking Mother by force.
So, just as he always had, he meant to give her a choice this time as well.
“Mother.”
The woman’s head, which had been thrashing and convulsing in a silent scream, slowly lifted.
“It’s almost lunchtime. Your son will provide the meal himself, so…”
Looking at that mother, the son offered a gentle proposal—
“Will you take it with your upper mouth? Or with your lower mouth?”
—while wearing a smile more steeped in fierce impulse than ever before.
