Unexpected Talent
As I lifted my mother-in-law's skirt right in front of her daughter, staring at her panties and groping her belly fat to humiliate her—no, to brand her—I glanced at Jihye, who was watching from beside me. I noticed an old scar on her left hand, right on the knuckle between her index and middle fingers. Looking up at her arms exposed by her short-sleeved T-shirt, they weren't thick like a man's, but they were slightly plump, showing a decent amount of muscle and bone density. Looking at her thighs and ass revealed by her dolphin shorts, she definitely looked like she could pull her own weight in a fight.
Next to her, I saw petite Minji. She was wearing a long-sleeved shirt and long sweatpants, so I couldn't see the thickness of her arms and thighs. Still, she was an Awakened asset I could put to use, so I needed to gauge her combat potential.
I finished drawing the graffiti on Yejeong's stomach and handed the highlighter to Jihye. Jihye, remembering exactly where that object had been inserted before, grimaced.
"Do you really have to make me touch something that went into there? It's so dirty."
"Didn't you say everything that comes out of Minji is clean?"
"Wait, Minji used that? Well, I guess only you, me, and Minji were in the house that day. It's not like you would've used it on yourself, Husband. But that thing was shoved into my hole too, you know? I really don't want to touch it."
"Minji is a thrifty housekeeper, so she probably wiped it clean before putting it back. It'll be fine. Besides, I think even your asshole is clean."
It was the truth. She looked like a slut and dressed like one, but she was a virgin, wasn't she? Her back door was bound to be clean.
I pushed Yejeong, who was sitting on the floor, flat onto her back, then pulled Minji over and laid her on top of Yejeong. Now this was a mother-daughter sandwich. But seriously, how fucking light was Minji that Yejeong looked completely comfortable? She had an entire adult female lying on top of her.
Now, let's check Minji's arms, thighs, and abs. As I pulled down Minji's sweatpants, she suddenly burst into tears.
"H-Heeg..."
"Do you... do you really have to fuck me from behind on top of my mom?"
"No, I'm not shoving anything up your ass right now. I'm just checking the thickness of your arms and thighs. You don't want to be helpless and get sexually assaulted or raped again if another guy like that day laborer ajussi attacks you, do you?"
I pulled her pants all the way down. She was wearing light green cotton panties with lace trim. Did she wear lace just to show me? Beneath the panties, her flat ass and thin thighs were exposed. Her effort was touching enough to give me a slight hard-on, but if I fucked her now, I'd be a liar who couldn't even keep his word from three seconds ago. I couldn't have that.
Squeeze, squeeze.
"Ah..."
I carefully checked Minji's muscles again. I got so absorbed in checking her muscle mass that I ended up rubbing her pussy a bit, but isn't that a mistake male masseuses make all the time when a pretty female client comes in?
Hmm...
That was one thing, but this was serious. With a body like this, no martial arts technique would work. Even if she managed to lock in a choke, a decent opponent would probably break out of it with sheer strength. If someone had a good build, even if Minji got mount position, they could probably just stand up carrying her weight with raw muscle.
Still, strength training was better than nothing. No matter how much she focused on Agility, she could still get caught in close-quarters standing or ground techniques, and even in a sword fight, it would be tough if she got overpowered in a clash of strength.
As I groped her from behind, Minji clung tightly to Yejeong like a koala. It was heartwarming to see mother and daughter getting along so well, so I pulled them apart. I lifted Minji into my arms with brute force, pulled her long-sleeved shirt up, and felt her abs and obliques.
Pinch. Poke, poke.
She tensed her stomach to keep her balance in the air, but it wasn't very firm.
As I pulled her long-sleeved shirt higher to check the muscle mass in her upper arms and forearms, Minji's sports bra caught my eye. For a sports bra, it had a pretty deep cleavage. Was the color ivory? Pink? I couldn't tell the exact shade, but for some reason, it looked incredibly sexy on Minji.
I pulled the bra straight up, exposing her nipples.
"Kyaaa!"
Minji screamed. When I thought about why she was reacting like this now, I realized that while I had fucked Yejeong in front of Minji plenty of times, I had never fucked Minji in front of Yejeong. Well, with a gorgeous milf walking around shaking her massive tits and ass right in front of me, it was only natural that I'd end up fucking Yejeong the most, no matter how young Minji was or how pretty Jihye was.
"You said you wouldn't do it in front of my mom!"
Minji shrieked in a hushed voice. I didn't know how one could shriek quietly, but she managed it.
"I said I wouldn't shove it up your ass. I never said I wouldn't expose your nipples. Don't worry, I'm not going to fuck you."
Since I had to keep my word to Minji, and looking at Jihye would probably make me go soft, I stripped off my pants and boxers and walked over to Yejeong.
"Yejeong, make me cum. Quick."
Handcuffed, Yejeong glanced at Minji with a troubled expression, but then she looked at Jihye and smirked triumphantly. Then, she began to suck my cock loudly, making sure they could hear every sound.
Slurp, shuck, slurp.
Smack!
She even pulled my cock out of her mouth halfway through to plant a kiss on the tip. It was less of a blowjob and more of a performance. Yejeong shot Minji a playful, smiling glance. Jihye looked back and forth between Yejeong and Minji, letting out a dry chuckle.
Unable to satisfy myself with just her mouth, I went to pull off Yejeong's panties, noticing that the color was similar to Minji's. Well, Yejeong's was light green, while Minji's was closer to white. I wondered if their nipples were a similar color too. Last time I checked, Yejeong's nipples had turned a pretty pink. I suddenly yanked Yejeong's bra up to compare her nipples to Minji's, but her nipples weren't pink anymore—they had reverted to their original color.
What was this? Did she temporarily rejuvenate from the mana, only to start aging again because of the radiation?
Ah, whatever. Let's just blow a load first and think later.
Slap, slap, slap.
"Ah, ahh, ahhh!"
Yejeong's groans were loud. At this rate, wouldn't her husband in the next room hear her?
As I was pounding away inside Yejeong's pussy, she suddenly spoke up.
"Darling, I've only ever been with two men in my life, but you are seriously amazing..."
Heeh, of course. I could tell that much just by looking at this bitch's reaction.
Looking at Yejeong's areolas and pussy, I suddenly thought of Jeonga.
Jeonga keeps getting younger. If I strip her naked, will she look closer to Jihye than Yejeong? Well, their figures are pretty similar anyway.
Spurt! Splurt! Splurt!
Since Yejeong was a married woman with a husband, she'd probably complain if I told her I was going to creampie her, so I just came inside her without a word. Hehehe.
When I pulled my cock out, Yejeong smirked, looking at Minji and Jihye.
I guess Yejeong enjoyed it too. That must mean Minji feels good when we do it too, she just doesn't show it. And Jihye clings to me even when I don't tell her to, so she must fucking love me.
I looked at the brand I had drawn on Yejeong's abdomen with the light green highlighter.
"Since Yejeong is my branded woman now, I won't handcuff you anymore."
I said it on a whim, feeling good after creampieing Yejeong. I immediately regretted it, but a real man couldn't go back on his word.
Yejeong beamed at Jihye and Minji, absolutely thrilled. Seeing Yejeong's beautiful smile, Minji's face went blank, while Jihye looked like she had just chewed on a piece of shit.
No use crying over spilled milk. Now that I was done checking Minji's muscle mass, it was time to make her work out.
"Minji, since your mom and I just worked on making you a little sister, let's get back to training."
Minji looked thrilled to hear that. I guess she wanted a little sister instead of an older brother too.
I looked around Minji's room. Was there anything useful for weight training? The 1-meter Hwando was 1.8 kg. The 90 cm sledgehammer was just over 3 kg, the 1.2-meter crowbar was around 3 kg, and the 90 cm fire axe was in the high 2 kg range.
"If we do strength training first, it'll be hard for you to hold a proper dagger-fighting stance or move quickly. Let's do combat practice before the weights."
I grabbed Minji's heart-shaped cushion—the one the Atlatl had punched a hole through last time—and headed out into the hallway. My women followed me out.
I pulled a dagger from my coat and handed it to Minji.
"But first, a light cardio warm-up. Run ten laps back and forth down the hallway with the dagger. Every time you run back to me, draw the blade from its sheath and stab this heart cushion I'm holding. The one the Atlatl put a hole in."
"Son-in-law Park, what's an Atlatl?"
"The gift Father-in-law made for you on Minji's birthday."
"Ah, that thing made out of a backscratcher? I don't think that was its name, though?"
"What does the name matter? It's not like it can kill an elephant anyway. Though Juho claims it can."
"Jihye, you brought your whip, right?"
"Of course. I always keep it on me."
Since we never knew when some bastard might launch a surprise attack, it was best to have at least one person armed.

In the meantime, Minji had already sprinted to the end of the hallway by Room 207 and rushed back, drawing her dagger as she lunged at me.
She wouldn't actually stab me, right? She was branded, after all.
Thud.
The dagger easily pierced the cushion.
Minji pulled the blade out, sheathed it, and sprinted back toward Room 201.
"Minji's surprisingly good at this. I thought she'd just stand there screaming 'What do I do, what do I do?' like some useless female cop."
"Yeah."
Pant, pant, wheeze...
Having finished all ten laps, Minji gasped for air. Still, she was more useful than I'd expected.
"Let's go inside and practice dagger combat. This kind of training is most effective when kept secret from others."
If the other officetel residents saw us, they might get wary.
As we headed back into Minji's apartment, I gave her a light hug and patted her ass, telling her she did a good job.
"It'll probably be best if Jihye, our resident expert, teaches you dagger combat."
"Got it."
