Monster (12)
The household gained one more member. Poison Human still didn't seem to have adjusted to the fact she was now part of this estate. Even sitting in her room, she wore an uneasy expression, and at mealtimes she watched our every move.
"How about trying on something like this?"
Sannyeo paid Poison Human's awkwardness little mind, but Seon-go made an effort to open her heart. Whenever there were pretty clothes, she had her try them on, and when seasonal foods arrived, she set some aside for her. Sometimes she even cooked herself and fed Poison Human.
"H-how is it?"
After a few days like that, Poison Human was gradually swept up in Seon-go's flow. Seon-go had a way of disarming people, treating them like family and drawing them in, and Poison Human fell headlong into it, naturally settling in as one of the household. Today, too, Poison Human was beside Seon-go showing off a pretty outfit, and Seon-go smiled with satisfaction as if she had raised her own daughter.
"Oh my, how pretty. How about a little turn? I need to see the back as well."
"L-like this?"
"What do you think? Isn't it so pretty?"
Seon-go threw questions my way as well. Watching Poison Human sway her waist gently, a pretty ornament dangling near her hip—the motion almost tail-like—combined with her awkwardly coquettish expression, I couldn't help but wonder if she was trying to seduce me.
At those times, I would wrap an arm around Seon-go's waist, nod, and say something like this.
"Truly beautiful. Your eye for beauty shines, my wife."
"Th-thank you. Um... uh... um..."
Poison Human would writhe, not knowing what to do with herself under our shower of compliments. She would hesitate, her lips twitching as she tried to address Seon-go, and each time she stalled, Seon-go would say to her firmly:
"Big Sister. You have to call me Big Sister."
"Big Sister..."
Then Poison Human would reluctantly call Seon-go Big Sister, and Seon-go would beam brightly and tap me with her hand, beside herself with joy.
"What should I do? She called me Big Sister. Big Sister."
I too couldn't hide my delight at this radiant side of Seon-go. It was going exactly as I'd thought.
******
"Big Sister."
"Yes. Come this way."
When hearts grow close, bodies grow close too. I guided things so that Seon-go would become even closer with Poison Human and cherish her more. Seon-go understood my intent and gave her love to Poison Human without reserve, and from some point on, Poison Human began to follow Seon-go as if she were her mother or real older sister.
She was a woman starved because she had never been able to form a family. If someone like Seon-go—a woman who could give boundless love—was placed beside her, she could hardly help but fall in completely.
"I hear there's a market opening in the lower village soon. Shall we go together?"
"I'd like that, Big Sister."
As she combed her hair, Seon-go made the affectionate suggestion. Poison Human then decided to go along without reservation, leaning her head against her and acting spoiled. I would come up beside Seon-go and say things like this.
"You two have grown remarkably close lately. At this rate I won't have any space to slip into—I'm almost jealous."
"Oh my, your place is always open, you know."
Seon-go replied to my joke with a sly smile, while Poison Human protested, flustered, clutching the hem of her clothes tightly.
"I-I like mister too."
Her prim, timid tone was so adorable that we looked at each other and laughed once more. Harvest season had come around at last.
******
"What do you think of the Tang Clan child?"
"She's such an adorable and kind girl. Honestly, I truly don't understand why the Tang Clan would lock such a good-hearted child underground and torment her."
While Poison Human went to bathe alone, I asked Seon-go about her. Seon-go didn't hold back in praising Poison Human, her face full of light. Along with a radiant smile, there was an undertone of sympathy, as if she truly lamented Poison Human's dark past. She too had once been locked up and suffered at the hands of the Crimson Ring Sect Leader.
Poison Human's wretched, pitiable past must not have felt like a stranger's story to her. Wine cups sat in the room. As we sipped modestly, cup by cup, amid light chatter, we would eventually melt into intoxication and slip into the bedroom—that was the natural order of things.
I raised my wine cup and asked her.
"You're that fond of her?"
"She's a pitiable child. I want to treat her better, look after her more."
Seon-go nodded as she said that. Even as she spoke, she kept sipping her wine cup out of bashfulness. The wine that had filled the small cup vanished again and again. A hazy intoxication spread through the room, the scent of wine subtly permeating the air. I poured more wine and said.
"Then you could make her your sworn sister."
I'd said it lightly, but the response didn't come easily. She blinked and studied my expression, then answered hesitantly.
"...Are you saying that sincerely?"
"When have you ever seen me joke about such matters? She's a pitiable child, and she has no family to rely on, doesn't she. If you've decided to look after her, what could be more certain than forming a familial bond?"
Seon-go wasn't fooled by my shameless answer. She narrowed her eyes, then smiled and said this.
"...I was curious if the suggestion truly sprang from pure goodwill."
When she cast her gaze at me like that, subtly searching, I couldn't lie. I rolled my eyes and spat out the truth.
"...It has been my dream to bed sisters."
But finding martial arts masters who were actual sisters was difficult, and I didn't have the time to entice such masters anyway, so instead I had decided to make sisters and then fuck them. Bringing Poison Human here and raising her so preciously, never once crossing the line until now—all of it was for that reason.
After she formed a sworn sisterhood with Seon-go, I wanted to see her lying beside Seon-go, crying out "Big Sister, Big Sister" as I took her. Just imagining it made my erection keep rising, and I also wanted to see Seon-go, thoroughly aroused, watching as her little sister was taken voyeuristically.
"...Pervert."
Seon-go's voice reached me. I raised my head and met her eyes, and she was wearing exactly the same expression as me. The corners of her mouth rose uncontrollably into a smirk, her face flushed pink, and her pupils were brimming with lust. I couldn't stop laughing because that expression was so ridiculous.
"For someone calling me a pervert, you're all smiles. What were you thinking?"
"...I was thinking—I've really gone and married a perverted husband."
"Is that truly all? You didn't think of anything else?"
"...I imagined lying that child down beside me, and being intimate with you. When I hold her hand tightly, she would make that cute voice, crying out 'Big Sister, Big Sister.' The child who was once the Poison Human of the Tang Clan, calling me Big Sister, just... like that..."
Seon-go stopped mid-sentence and wiped her lips. Apparently the intoxication was making her drool. I held her, her body unsteady, and stroked her head. Seeing her look so overcome with happiness from mere thoughts—this truly was my wife.
A warm atmosphere filled the room. She leaned her head against me, and as I stroked her head, I soaked deeply into the scent of spring.

Several days passed. Seon-go and Poison Human grew even more intimate, and Poison Human even began to bring up personal stories from her days with the Tang Clan. After hearing such stories, Seon-go would bring up the time she was tormented by the Crimson Ring Sect, striving to share in her pain.
After realizing they shared similar experiences of suffering, Poison Human followed Seon-go as her big sister even more devotedly.
"Hey, listen. How would you like to be my little sister? My real little sister."
It was at this point that Seon-go brought up the sisterhood talk. It was a fine, pleasant day, and they were alone together drinking tea.
"What?"
Poison Human looked at Seon-go with a bewildered expression. But after seeing Seon-go gaze at her so seriously, her face full of fervor, she seemed to realize that Seon-go wasn't joking.
"Since we've come this far... well... it's good to live as family. I want you to keep calling me Big Sister."
Poison Human showed signs of hesitation at Seon-go's words. It wasn't because she disliked Seon-go.
"B-but, Big Sister... I-I like mister too, and if we do that..."
The family bond was the problem. She thought that if Seon-go became her big sister, Poison Human couldn't marry Docheol. But to Docheol and Seon-go, such old-fashioned customs or ethical norms weren't a problem at all. Rather, that sense of moral transgression was like a seasoning to them.
"What's wrong with sisters marrying the same man? And honestly, I'd welcome it if you entered as our husband's wife. If not a cute and kind girl like you, who else could do it? You'd be my little sister, and also our husband's wife."
"I-is that... is that really okay? Sh-shouldn't we get mister's permission too?"
"Does Docheol seem like the kind of person who would dislike something like that to you?"
Poison Human briefly reflected on everything she'd experienced with Docheol up until now. The image of Docheol kissing her, making her touch his cock, tormenting her nipples—it all flickered past like viewing a folding screen painting. The man who displayed a consistent nature throughout all those acts.
That was Docheol.
After thinking for a moment, Poison Human nodded and said.
"...I don't think he would."
A child who truly learned fast.
