Night Opening at Yongsan Base
"D-Daughter's right next to meee!?"
On the drive home, Cha Saea tried hard to make sense of everything she had done that day.
Why, the moment Hajun messaged her, had she gone all the way to the supermarket just to prepare a lunchbox for him?
Why, when his cock had ravaged her throat, had her lower belly clenched and throbbed with even greater pleasure?
And when she had walked across campus hand-in-hand with Hajun, when he had eaten the lunch she made—why had her heart hammered so wildly in her chest…
Every feeling that had flooded her in those moments was something Saea neither wanted to accept nor was allowed to accept.
Yet something else unsettled her heart far more than all of that.
Why had Hajun's semen smelled so fragrant and tasted so delicious?
Why, after swallowing it, had her body and mind burned with an uncontrollable heat and arousal?
No matter how she turned it over, she could find no proper reason, and that was what confused her most of all.
Do I… have a fetish like that?
This had been the first time she had ever swallowed cum, so Saea could not accurately judge her own condition. Even now, driving home, her whole body still burned and her womb kept clenching and ringing; the urge to turn the car around, go straight back to Hajun, and take his cock deep into her pussy only kept growing.
No! Think of Seoa. Cha Saea! Get a grip.
Saea bit down hard on her lip, forced herself to picture the daughter she loved more than anything, and somehow suppressed the boiling desire as she headed home.
Even after she arrived, the raging lust refused to subside. The instant the front door shut behind her, Saea stripped off every piece of clothing and leaned back against the sofa, fingers already rubbing her pussy.

"Hnn… haah… haah!!"
Not enough…
All of it only drove home once more that masturbation alone could never satisfy her. Cha Saea stopped stroking her folds, body trembling, and crawled across the living-room floor to the bag she had tossed down. She pulled out her phone.
Dump every feeling I'm having right now into this and then forget it. Get a grip, Cha Saea! You don't even like Kim Hajun, and you're not some deranged masochist sow. This account is nothing but a tool for venting desire…
Soothing herself that way, Saea opened the sow account and began composing a post.
During their training sessions Hajun took photos of Saea whenever he had a free moment, so material for the post was overflowing. The picture she chose for today was one in which she herself did not appear at all—only a plastic lunchbox filled with salad that had been thoroughly doused in cum.
Until now, every post Saea had uploaded—whether photo or video—had centered on her own body. Emphasizing her lewd figure together with filthy captions let her vent sexual desire while she reveled in the feverish reactions of her subscribers; that had always brought her great pleasure.
But today's photo was different. Nowhere in the frame was Cha Saea's body visible. The tone of the post itself had shifted as well. Of course, after the contract with Hajun she had already begun seasoning her posts with contempt for the subscribers, yet that had only been under his orders and the degree had been mild.
Up until the post she was about to upload…
Exactly as she had once treated Hajun like a herbivore and used him as mere source material for her own desire before the contract—no, even more viciously—Saea now wrote about the subscribers who spent time and money on her as though they were inferior loser men.
After hitting post, Saea found herself, almost without realizing it, naturally imagining Hajun's reaction when he saw it.
Haah… Hajun will like this, right?
The thought that she had freely toyed with the emotions of so many people, and the thought that Kim Hajun would enjoy the post, made Cha Saea's body burn even hotter. The moment she had opened the Tiafans app she had only wanted to relieve her urge; while writing the post she had completely forgotten her original purpose. Seized by an even greater sexual exaltation than before, Saea rose from the sofa, caressing her breasts and pussy as she headed for her room.
More… more…! I need stronger stimulation. Hnn…! Hhk!
After parting with Auntie Saea I returned to the library, sent Lisa noona the verification photo, and was studying when a text arrived from Seoa.
I expected her to suggest some popular restaurant at most, but Seoa came out with something I never saw coming.
Yongsan Base night opening. After the former military base was converted into a public park, they were temporarily opening the remaining undemolished base facilities to civilians for a limited time.
Even through plain text I could feel Seoa's anticipation. Anyone could see this was a date invitation.
Ever since the day she had been rejected without even managing to confess, Seoa had grown more assertive. She would suddenly link arms while we walked, and she often kissed me on the cheek when we parted. I liked her well enough that I never refused, yet I knew I could not keep treating her this ambiguously forever.
Haa… I have no intention of actually dating her, so is it okay to keep handling Seoa with this half-hearted attitude?
Just today I had ravaged her mother's mouth with my cock. The moment Auntie Saea came to mind, my heart leaned toward turning Seoa down.
But that thought was immediately swallowed by a far dirtier idea that rose behind it.
Seoa, who had been answering instantly, went silent for more than a minute. Of course she did. How many people in the world receive a date invitation and immediately suggest bringing the friend's mom along? She must have been thrown off.
Thinking of the specially prepared exclusive lunchbox, I was pretty sure Auntie would have made one for me even if Seoa hadn't asked—but the care Seoa showed for me still pricked my conscience a little. I deliberately ignored the disappointment I could feel even through text and settled on the place and time.
The second I finished with Seoa I texted Auntie Saea.
Yes! “Training the mom in secret at a former military base right under the daughter's nose.” How the fuck am I supposed to resist that? Seoa just handed me a perfect opportunity.
While texting Auntie, every scrap of guilt I had felt toward Seoa vanished cleanly. In its place my mind filled with thoughts of Auntie's filthy body.
Of course, since Seoa would be with us I couldn't just fuck Auntie openly—but even imagining the situations was insanely hot.
After that I spent the remaining time looking up night-opening reviews and planning how I would train Auntie Saea, then arrived at Yongsan Station at 6:30. Both of them must have come early; by the time I got there they were already chatting.
Seoa, who had been talking with Auntie, spotted me, waved, and ran over to glue herself to my arm, linking elbows tightly. She wore a white blouse under a mint cardigan, a black tennis skirt that ended above the knee, and leather boots.

Seoa really is goddamn pretty.
I greeted Seoa cheerfully, then locked eyes with Auntie Saea, who was watching us with a thoroughly displeased expression. Auntie wore wide-leg denim pants and a slightly thick white cardigan; the glimpse of skin between the fastened buttons at her waist suggested she had a white crop top that stopped above the navel underneath.
If she takes the cardigan off, that's a pretty bold outfit. Did she do that on purpose?
The moment Seoa looked up at me and then glanced back at her mother, Auntie's face immediately softened into something gentle.
Whoa, look at that expression management. A second ago she was glaring like she wanted to eat me alive.
"Seoa, if you cling like that Hajun might feel pressured…"
"Hajun and I are reeeally close, so this much skinship is fine! Right, Hajun?"
Seoa tipped her face back up to me. The instant her gaze locked onto mine, Auntie mouthed words at me.
You watch yourself.
I couldn't completely ignore Auntie's mood, so I gently peeled Seoa's arm off mine. The second disappointment flashed across her face I interlaced our fingers instead and raised our joined hands to the height of her chest.
"If we walk stuck together like that we'll just bother everyone around us. How about we hold hands instead of linking arms?"
"Yeah, okay♡"
After that, all the way from the station to the base, Seoa chattered nonstop about her day.
"So we were checking the lighting… it's my first time so I kept messing up and nothing went right. I want to do well, but the seniors only scold me… If it's going to be like this I shouldn't have joined the lighting team, wuu…"
"It's the team that only takes the prettiest people in the department, right? Who else could get in if not our Seoa?"
Auntie Saea soothed her grumbling daughter. Seoa's theater department had to produce its own performances, so every freshman had to join a team—lighting, props, makeup, and so on. As an outsider I didn't fully get it, but because the lighting team had produced so many famous seniors it held the most power in the department. That power was strong enough that lighting picked the most attractive or talented freshmen first, and only afterward did the other teams divide up whoever was left. With Seoa's looks, she had received the call the moment she enrolled.
Even though we arrived a full thirty minutes before the 7:30 opening, a long line already stretched from the entrance.
Ah. Too many people is going to be a problem.
My goal was training Auntie Saea; a huge crowd would only get in the way. Seeing the endless line soured my mood, so I switched on the vibe she was supposed to have inside her pussy. The surrounding chatter completely masked the buzzing.
But—
"Hkieeit!!?"
Auntie clearly never expected the vibe to go off right there. She let out a moan and collapsed onto the ground.
"Mom, what's wrong all of a sudden?"
"I-It's nothing. I just twisted my ankle for a second…"
While Seoa crouched in front of Auntie with a worried face and checked her ankle, Auntie turned her head toward me and shot a razor-sharp glare.
You. Are you really going to do this?
Because Seoa couldn't overhear, Auntie only mouthed the words, and the sight was pretty cute.
I just shrugged as if I had no idea what she meant. That clearly pissed her off; her eyelids trembled faintly.
Supported by Seoa, Auntie Saea rose and after that refused to look my way. While we waited in line Seoa kept pouring out stories nonstop at both Auntie and me.
"…So I got offered an underwear modeling job for Company C… No no! It's not sexy stuff. It's a brand Mom wears a lot too. Do you think I should do it?"
"Hmm… Company C seems trustworthy. Mom will leave the choice to Seoa."
The moment Auntie gave permission, Seoa turned sparkling eyes on me.
"What do… you think?"
"Why are you asking Hajun that?"
"Mom, I should hear Hajun's opinion too. He's my most precious friend… and who knows what might happen later."
Seoa's face flushed pink as she twisted her body a little. Auntie Saea's eyebrows twitched at the sight.
"I think the same as Auntie. If you want to do it, you should. Modeling for Company C is a real opportunity, right?"
Apparently my answer was the wrong one for Seoa. She puffed her cheeks and answered in a slightly sulky tone.
"You wouldn't care even if I stood in front of other people wearing nothing but underwear?"
"Come on, Seoa, it's work. Lisa noona's photo shoots get pretty high-level too, but nobody thinks they're trashy or dirty."
Ah. Fuck. I shouldn't have brought up Lisa noona.
She was the only model I knew, so it had slipped out naturally, but the second I remembered the tension between the two of them I regretted it. Seoa's expression stiffened a little; she let go of my hand and went over to Auntie ahead of us, linking arms with her instead. A bright smile spread across Auntie Saea's face.
"Who is this Lisa noona that made my daughter sulk?"
"There's this professor at our school who pretends to be Hajun's mom. Mom, you'd recognize her if you saw the shoots—that model who shows up a lot in fashion magazines with the purple eyes."
After that I simply admired the beautiful backs of mother and daughter standing in front of me in line while I checked the night-opening master map. Right near the entrance a booth caught my eye perfectly.
「Rent a military uniform and enjoy Yongsan Base more vividly.」
I had never been in the army and neither mother nor daughter had any connection to the military, yet a manga I had recently found impressive on a certain site immediately floated up in my head.
It was about blackmailing a battalion commander about to get promoted and fucking her… With Auntie, I could totally reenact that, right?
