The Beautiful Mother-in-Law Who Finally Succumbed
‘Oh no, what do I do!’
After rationalizing it every which way, Sophia’s lewd fingers—those same fingers that had just been teasing her son-in-law and adopted son, Geum Taeyang, as if he were her own daughter’s plaything—sent waves of pleasure surging from her pussy straight through her womb, up her spine, and crashing into her frontal lobe. Her eyes widened into perfect circles in that instant.
‘What kind of stimulation is this?!’
The pleasure was on an entirely different level from the masturbation she had experienced just days ago. It was so intense that it shot straight from her pussy into her brain.
‘I only rubbed it lightly, yet it feels like mana energy is being stimulated! And my heart is pounding even harder!’
The orgasm she had reached after watching Geum Taeyang and Athena have sex had been deep and lingering, like rich bone broth from a master restaurant—thick, hot, and all-encompassing. But this was different. It was like an electric shock, sharp and overwhelming.
And the reason for this change was simple: the thrill of doing something forbidden.
‘Is this why barbarian couples who had fallen into sexless marriages started having outdoor sex? It really does feel like an entirely different world.’
Yes. It was the thrill. The thought of secretly masturbating behind Geum Taeyang like a cat burglar made Sophia’s heart race with the fear of being caught—and that fear transformed into pure, exhilarating pleasure that amplified every sensation.
Sophia had almost never had outdoor sex. She had never done anything remotely sneaky like this either. The few times she had tried anything outside had been in places so safe it barely counted as outdoor sex at all. This was, for all intents and purposes, her first taste of sexual dopamine laced with genuine thrill.
‘Just a little stimulation and…’
Schlick…!
Sophia’s mischievous milf fingers teased her pussy once more.
Zzzzt!
‘Hnnngh! What do I do…? The stimulation is so strong…!’
Another electric jolt shot from her pussy through her womb and straight into her brain, making her voluptuous body tremble violently.
Schlick…! Squelch…! Slap…! Plap…!
‘Anyway, I’m already soaked from the shower, so he won’t notice the love juices… But somehow… I kind of wish he would notice… Haaah… That’s far too shameful… As the Great Mother, how could I think something so vulgar…?’
Twitch…! Twitch…! Zzt! Twitch…! Zzzzt!
She wanted to feel more. So Sophia grew bolder, standing right behind her hardworking son-in-law as he worked and stimulating herself even more aggressively. Her thoughts, almost instinctively, drifted toward something even more wicked and immoral. Her instincts as a born barbarian sex fiend were speaking clearly: if she wanted to fully enjoy this thrill-induced dopamine, she had to walk the razor’s edge between morality and immorality.
And it was working perfectly. Sophia’s body trembled with the thrill of transgression, the numbness of her long sexless period already forgotten. Her sensitivity was sharper than it had been even in her maiden days, and her body twitched vulgarly with every touch.
Then Geum Taeyang spoke.
“Great Mother. I think I did something terrible to you, the Great Mother I love so much, last time.”
Her son-in-law, who had become her daughter’s plaything, offered an honest apology in a sincere tone.
“Huh…? W-what do you mean, Taeyang…? Are you talking about what happened five days ago…?”
At that moment, Sophia’s voice trembled because the pleasure was threatening to push her over the edge into orgasm at any second. But with the composure of a woman who had lived many years, she quickly steadied herself with a deep breath and answered properly.
“Yes. Having sex with Athena right in front of you, Great Mother.”
“Oh dear, why would you think that was terrible? I didn’t feel that way at all.”
Plap…! Schlick…! Squelch…!
Geum Taeyang admitted, in an embarrassed tone, that he was indeed referring to the sex show he had put on with Athena. Sophia responded with a truly affectionate voice, gently comforting him—while her hands, hidden behind his back, grew even more aggressive in treating him like her personal plaything.
“Ever since that day, Great Mother, you’ve seemed much brighter than before. Watching you like that, I wondered if you were just trying to shake off the awkwardness after seeing something so shocking…”
Recently, the Great Mother’s energy had risen sharply. It wasn’t a bad thing—in fact, it was good—but the timing made Geum Taeyang suspicious. Looking back, he really had fucked Athena like a beast right in front of her. Even the most generous mother-in-law might have felt uncomfortable. So he wondered if Sophia, being the way she was, was trying to cover up that discomfort with an overly cheerful attitude.
“I was too greedy. I wanted to help Athena overcome her shyness, and the mood was so heated that I couldn’t control my lust. I think I showed more than necessary, Great Mother.”
Even while Sophia was watching her, Athena had felt so intensely aroused by the fetishistic situation that Geum Taeyang’s own desire to conquer had surged, and he had used every filthy position imaginable to give her even greater pleasure. Remembering those scenes himself, even Geum Taeyang had to admit that this was too much—even for barbarians who were sometimes treated like animals by civilized people. He wasn’t a real beast, after all.
‘Haaah…! My sweet child misunderstood…! Hnnngh…! I need to comfort him, so why am I just standing here watching while I touch myself…?’
Schlick…! Squelch…! Schlick…! Squish…!

It was a perfect misunderstanding. If this had been the usual Sophia, she would have immediately reassured him that it wasn’t because of that. But right now, she couldn’t. The sight of her son-in-law blaming himself was so adorable that the image of her secretly masturbating while he was wallowing in guilt was unbearably arousing. She would comfort him eventually—but first, she desperately needed to enjoy this pleasure a little longer.
“That’s a misunderstanding, Taeyang.”
“A misunderstanding?”
“Yes, it is. I didn’t feel uncomfortable at all.”
Though she regretted not being able to enjoy it longer, Sophia couldn’t bear to let her self-blaming son-in-law suffer any more, so she began to comfort him.
“On the contrary, I felt the greatest joy I’ve had in years. Because I got to see my daughter receiving such deep love from her husband with my own eyes.”
Her voice was filled with genuine sincerity. It was true that she was happy Athena was being loved. Of course, a large part of her recent high energy came from the orgasms she herself had experienced for the first time in ages, but that was beside the point.
“Do you know what the greatest happiness is for a barbarian woman, Taeyang? It’s receiving passionate, yet tender love from the one person she wants to look at for the rest of her life. You were giving Athena exactly that kind of love.”
“Haha…! I just like Athena so much… so I wanted to treat her well…”
“Hohoho! Yes, that’s right. That’s the kind of heart that matters. In the end, the right answer comes from a sincere heart like that. Athena felt it from you, and so did I, watching you.”
“I see… Hmm…”
In barbarian society, which practiced polygamy, barbarian women still looked only at their husband as long as he didn’t abandon them. They craved his love. Even if they only received it once a week, they wanted it to be genuine. Having seen many barbarian couples, Sophia knew what kind of man could maintain such devotion even while building a harem—and she was certain her son-in-law, Geum Taeyang, was exactly that kind of man.
“So how could I possibly feel bad? A mother’s greatest happiness is seeing her children live well. So don’t think that way. Instead, show me even more of you two living happily together.”
“Hahaha! Please look forward to it, Great Mother! I still have countless things I want to do for Athena.”
“And just in case, let me say this. Taeyang, you’re the one who will succeed the chieftain. Men as considerate as you tend to focus on only one woman. That won’t do. One of my regrets while supporting the chieftain is that he focused on me for far too long.”
“Of course, Great Mother! With this overflowing stamina, Athena alone can’t possibly handle it all!”
“Hohoho! The future of our Barbara clan is bright indeed.”
After reassuring Geum Taeyang that he was doing well, Sophia didn’t forget to give him important advice. This was, after all, a barbarian society with different common sense from the civilized world. In a harsh environment, for the clan to survive, superior genes needed to be spread far and wide—and they all knew it. Yet even after Sophia’s persuasion, Conan had focused solely on her until his early forties. Only later had he begun taking concubines from outside. Sophia worried that Geum Taeyang, who was so devoted to Athena, might do the same.
But Geum Taeyang was not the type to fail his harem-building mission. He confidently declared that there was no need to worry.
‘A strong man like Geum Taeyang who builds a harem and spreads his seed… How much more magnificent and majestic will he become compared to now…?’
Schlick…! Squish…! Squish…!
Sophia continued to stimulate her pussy while using even her advice to him as material for her fantasy. A strong man was the ideal husband that barbarian women most wanted to serve. And one of the symbols of a strong man among barbarians was having an excellent harem. Watching Geum Taeyang boldly declare his ambitions for a harem made Sophia imagine his future self as an alpha male surrounded by fine females, sending her into another dimension of excitement.
‘I want to touch my breasts… At this level of sensation, touching my breasts would give me even deeper pleasure…!’
Just touching her pussy was no longer enough. Sophia wanted to feel the image of Geum Taeyang, who had grown into an alpha male, by caressing her own symbolic 80J breasts.
‘But if I do that, milk will come out…’
Right now, her nipples were filled with milk due to her heightened excitement, and they had become so sensitive that even the slightest touch would make milk leak out. Unlike her love juices, the milky white color of her milk would be visible to Geum Taeyang, so she hesitated.
Just then, a situation arose that would solve Sophia’s dilemma.
“Great Mother! I’ve fixed the shower. Shall I turn it on?”
Geum Taeyang had finished repairing the broken shower. Thinking that Sophia had been in the middle of showering, he figured he should let her continue right away. So he asked if it was okay to test the water.
“Y-yes! Turn it on strong, Taeyang!”
“Yes, Great Mother!”
A strong stream of water would cover any milk that leaked out. Having made that calculation, Sophia requested that he turn on the shower in an excited tone.
—Shhhhhhh!!
Soon, a powerful stream of water poured out from the showerhead Geum Taeyang had turned on.
Whoosh…! Whoosh…!
At that exact moment, Sophia pressed down on her massive breasts as if stimulating them.
‘T-This is…!! Oh Goddess Gaia…!!’
The pleasure that wrapped around her body was like nothing of this world. Sophia’s eyes naturally closed, and though no sound escaped her slightly parted lips, the name of the goddess Gaia slipped out on its own.
Drip…! Drip…!
The milk that had slightly leaked out was naturally washed away by the strong stream of water.
“If Great Mother is happy, then I’m happy too.”
“Yes, it feels wonderful, Taeyang. Thank you for fixing the shower.”
Stroke…! Stroke…!

Geum Taeyang crossed his arms and looked at Sophia with a satisfied expression, while Sophia pretended to be showering and savored the deep pleasure of her masturbation that had overtaken her entire body.
“What letter is that? Is it from Merchant Leader Nadia?”
“Yeah, someone from the communications office delivered it today.”
One week later, Geum Taeyang received a letter from Nadia.
‘The most important setup is complete.’
The contents of the letter perfectly fulfilled what he had intended—two hundred percent.
