The Beautiful Mother-in-Law's Naked Indulgence
“I thought you’d be wearing a towel at least. Our Great Mother really lives up to her barbarian roots.”
In civilized society, if a man walked into the shower room, the woman would at least cover her lower half with a towel even if things were about to get heated. She might try to hide her breasts with her hands too. Geum Taeyang had momentarily pictured that scene, since he was stepping into a civilized shower room rather than the tribe’s usual open-air bath. But no matter how affectionate a mother-in-law she was, Sophia was still a barbarian woman. True to her pure-blooded barbarian nature, this voluptuous milf greeted her son-in-law without bothering to cover herself with a towel or even her hands—breasts and sex fully exposed.
“Hm? What’s wrong? Got something on my face, dear son-in-law?”
Geum Taeyang had frozen the moment he entered, so Great Mother Sophia tilted her head in confusion.
“N-no, Great Mother! Haha! I was just stunned by your beauty!”
“Hohoho! Marriage has made you even more silver-tongued. It’s hot outside, isn’t it? Your clothes are soaked with sweat, my Taeyang.”
Swish! Swish! Swish!
Geum Taeyang tried to play it off with smooth talk—though it was closer to outright flirting. Sophia, who found her son-in-law and adopted son endlessly adorable, approached him completely naked and gently wiped the sweat from his cheeks and neck.
Whoa… up close like this, her pubic hair looks even more explicit. Right… this is the first time I’ve seen Great Mother’s sex and her bush. No wonder I froze for a second.
Geum Taeyang quickly realized why he had reacted so strongly. The noble Great Mother wasn’t like other barbarian women who openly had sex outdoors or masturbated when their husbands were away on business. For fourteen years, he had never once seen her sex or her pubic hair. He had seen her breasts plenty of times, but her lower half was different. She had bathed him naked when he was a baby, but he had arrived at the Gaia Tribe at age nine. Even when they bathed in the Raonjena River, Sophia usually wore panties. After fourteen years of her carefully avoiding showing him anything, he was suddenly confronted with her completely bare sex in the most unexpected situation.
“Then I’ll take a look at the shower, Great Mother.”
“Go ahead. If you need any help, just say so.”
Geum Taeyang savored the lingering image of that primal beauty he had experienced for the first time in fourteen years, then got to work.
“This part’s loose. That’s why too much water pressure surges up at once and the water-stone sensor overreacts trying to regulate it.”
“Mmm… I see. That makes sense.”
After checking here and there, Geum Taeyang quickly identified the problem and explained it to his mother-in-law.
“I’ll fix it now. You can watch and learn while I do it, Great Mother.”
Swish!
“Alright. I’ll do that.”
Geum Taeyang rolled up his sleeves to begin the repair in earnest.
“……”
While watching him work on the shower, Sophia suddenly spoke.
“Our Taeyang is truly amazing.”
“Me?”
“Of course. Who else would it be?”
The timing was so abrupt that Geum Taeyang looked puzzled, but Sophia simply confirmed it as obvious.
“I was really worried about how to get the vaccines. No matter how much I thought about it, there didn’t seem to be a way. The only option I could think of was trading with the merchants.”
Then Sophia explained why she had to praise him.
“But after you returned from the academy and took charge, we suddenly received free vaccines for the children and livestock. It really felt like a miracle.”
“Hahaha! That’s because you treated the Jasmine Merchant Guild so well while I was busy preparing for the wedding, Great Mother.”
“That’s not it, dear. I saw it clearly. Merchant Princess Nadia has enormous trust in you. Even I can see why. You graduated at the top of the Imperial Academy and your manners aren’t like those of typical barbarian men. For merchants who value trust and ability, how could they not want to do business with you?”
This year, Sophia’s number one priority had been obtaining vaccines. Last year the tribe hadn’t suffered as badly from the flu as the year before, but they were still completely defenseless. She had noticed the merchant guilds showing interest and tried her best, but it had been incredibly difficult. Then Geum Taeyang returned and achieved it almost immediately. How could Sophia not praise him?
Her analysis isn’t wrong. Though Nadia’s trust in me is closer to obsession. A very personal obsession.
Even Geum Taeyang himself knew his actions were pure cheat-mode. But personal feelings were stronger than logic, and Nadia—hurt that Geum Taeyang, unlike other men, hadn’t fallen for her—was now pouring even more resources his way. In that case, he might as well take full advantage.
“On top of that, you built that strange device as soon as I brought the materials. Watching you quickly diagnose and fix the shower like this, I’m sure you’ll be able to build the flood-control embankment too.”
“Yes! Look forward to it, Great Mother! I’ll have it finished before August at the latest. I’ve already finished discussing everything with the Jasmine Merchant Guild’s contact.”
“Oh my! You really are amazing, our Taeyang! Our son is the treasure of the Gaia Tribe—a true treasure!”
“Hahahaha! I’m so glad you’re happy, Great Mother!”
Nadia had established a Jasmine Merchant Guild outpost in the small village nearest to Cargo Forest to maintain constant communication with the Gaia Tribe. Over the past twenty days, Geum Taeyang had met with them several times and discussed many things, while Nadia continued to receive regular updates on the situation here.
“Just wait a little longer, Great Mother! I’m almost done fixing the shower!”
Creak! Creak!
Excited by Sophia’s happiness, Geum Taeyang worked on the shower with even more enthusiasm.
How reliable our Taeyang is. To think that weak, frail child grew up into such a strong, dependable man.
Smiling warmly…!
Watching him, Sophia couldn’t help but smile like a proud mother. But then—
Oh my, those arms…!
Once Geum Taeyang started using real strength, his back view made it impossible for Sophia to see him with only a mother’s smile.
Up close like this, he looks even more wild… Those smooth, sculpted muscles…

One of the things that makes a woman find a man sexy is watching him work. And if that man is devastatingly handsome with a great body? Geum Taeyang was tightening screws with his sleeves rolled up and no screwdriver, veins and muscles in his forearms standing out sharply.
He controlled our daughter’s body like that too… The way he handled Athena while she thrashed like a live fish, like he was taming her—those forearms left quite an impression.
Moreover, Sophia had already indirectly experienced that this body wasn’t just visually impressive. Athena, who had reached the level of Tessadar, was a wild horse, yet Geum Taeyang had controlled her as easily as any ordinary female with his solid physique.
Oh my! Oh my! What am I supposed to do about that butt of his?!
Suddenly, Geum Taeyang crouched into a half-squat to check the shower water flow. His buttocks filled Sophia’s direct line of sight, creating a sight she absolutely could not look away from.
The way he folded Athena in half and pressed her down! Every time, his butt would flush bright red while he—
Of course, the sex between Geum Taeyang and Athena five days ago in front of Sophia hadn’t ended after just one round. Once he got going, five rounds was the minimum. That day they had done it ten times, and Sophia had watched every single session head-on under the excuse that Geum Taeyang had asked her to observe. How many different positions had been used, and how intently had Sophia watched them all? Especially when he folded Athena like a sandwich in that half-squat position and pounded into her, the sight of his buttocks and thighs pumping contrasted so dramatically with his noble face that it created an even more intense sexual atmosphere.
Mmm… I-I shouldn’t be doing this…
Seeing Geum Taeyang like this—a capable man at work, a handsome man with a well-maintained body, a practical macho who knew how to ravish and satisfy a woman like a beast—Sophia couldn’t hide her troubled expression.
No matter what, I shouldn’t be looking at Taeyang directly and feeling this way…
Swoooosh…!
And the reason for her distress became blatantly obvious through her left hand slowly moving somewhere.
Slurp…!
The destination of Sophia’s lowered left hand was none other than her milf sex.
I have my dignity… I shouldn’t be secretly masturbating while watching him like this…
Why had her hand gone there? Because she felt aroused and her sex had started to itch. Because she wanted to stimulate it and feel pleasure. Five days ago, after watching Geum Taeyang and Athena’s ten intense beast-like sessions right in front of her, the 42-year-old sexless milf Sophia had become soaking wet. What had she done when she returned to the chieftain’s tent that morning? Naturally, she had furiously masturbated.
Since we’re all adults, it was something that could be forgiven, but…
How could a mother-in-law and adoptive mother do such a thing? That was only in some human nations’ stories. In barbarian society, an adult’s masturbation was considered a very tame way to relieve sexual desire—because extremely perverted beast-like sex was so common. So even though Sophia had enjoyed that storm of masturbation, she still felt it was shameless to use Geum Taeyang as her masturbation material right beside him like this.
But I can’t forget it… that catharsis… it felt like I was rejuvenated…
Yet her hand had still moved. It had truly felt incredible. It had been so long since her lower half had gotten that wet. No wonder there were so many vanilla oil jars in the chieftain’s tent. While some were for sharing with other barbarian women, Sophia herself had long since reached the point where she needed to slather vanilla oil all over before she could have proper barbarian-style sex with the chieftain. So Sophia had thought: I’ve already fulfilled my usefulness as a barbarian female. From now on, I’ll just live diligently as the Great Mother. She had judged herself that way. But then this happened. Just watching Geum Taeyang’s sex had made her wetter than she had been even in her virgin days.
I really reached climax after so long… Especially that level of orgasm from masturbation… whew…
That wetness had continued even after returning to the chieftain’s tent, and only after masturbating to climax had it finally calmed down. And those climaxes weren’t ordinary—they were on the same level of pleasure she used to feel with Conan’s cock in her prime.
I feel very sorry and embarrassed toward our son, but… if I can restore even a little of my feminine self-esteem this way, won’t my relationship with the chieftain improve too…?
The climax she had felt back then hadn’t ended with just that moment’s pleasure. Once her long-ignored sexual frustration was somewhat relieved, Sophia’s daily energy had risen. She treated the chieftain better and showed even more vitality while caring for the tribe members. Experiencing that positive cycle made it hard for her to resist this sweet temptation, even though she felt guilty toward her adopted son. And so, eventually—
Schlick…!

Her lewd fingers began to play, using her son-in-law and adopted son Geum Taeyang as her masturbation material to stimulate her milf sex.
