My Position is in Jeopardy
Unnie had made a friend—Yoon Seoha's older sister—and now Unnie thought of herself as Seoyoon.
...Isn't this dangerous?
It was a thought that struck her while working out at the gym and filming a video, just like any other day.
She figured there was no helping how women flocked to Seoha. Even in her eyes, Seoha more than deserved it.
The problem was that those women weren't females like Seoyoon, but futanari like Seoha.
...Then my spot's in danger.
At this rate, she might get demoted from first girlfriend to onahole.
Of course, as Yoon Seoyoon, she'd be fine with that.
No—honestly, she'd love it. Seoha treating her like a girlfriend, like a woman, filled her with joy, but just being used as an onahole would make her ecstatic too.
The issue was, once demoted to onahole, Seoha probably wouldn't give her another glance.
She could handle being alone in that role, but with other girlfriends around, why bother with some toy?
If you had a girlfriend who obeyed your every whim, you'd use her, not some disposable onahole.
"...Pregnancy's the only way, huh."
Ignoring the startled glances from nearby members, Yoon Seoyoon stared at her reflection in the mirror.

"...Not exactly the super-fertile type, but... yeah, this is pretty decent... No, is it still lacking...?"
At least twins would solidify her role as the big sister.
"Tch... Our genes should be a perfect match..."
Genetic compatibility between blood siblings was top-tier common sense—at least in her head. No matter what others said.
And yet, despite years of nonstop raw creampies, no pregnancy news.
"...Guess I need those ovulation drugs after all."
She'd held off before, worried about side effects. But she couldn't put it off anymore.
Sure, just seeing Seoha made her womb ache, her pussy drool, and her uterus drop on instinct—but drugs would boost the odds even more.
"There's that adult pharmacy near the company..."
It was more of a sex shop than a proper pharmacy, but since it sold meds, that's what they called it.
Unlike regular cold pills, they stocked mostly contraceptives, ovulation drugs, aphrodisiacs, and such—earning it a special "adult pharmacy" category.
"...Um, Teacher Seoyoon."
"...Yes?"
"Oh, you free tonight...?"
"...Tonight?"
Yoon Seoyoon squinted at the female approaching her.
Even after parading around in trashy clothes, spilling precious Seoha cum everywhere to advertise "I'm someone's onahole," her popularity hadn't dipped.
If anything, it rose among the women.
The logic went: Oh, she has a boyfriend → Guess that means no girlfriend?
Not everyone thought that way, of course—the main vibe was more "Date Teacher Seoyoon, score her boyfriend too?"
Why it's like this... is obvious.
Gym members, other female trainers—they were all stunning.
Whether themselves or friends, plenty had ties to the "company." And those folks always showed freakish sexual sides.
Had to be that.
"Sorry. Got something tonight."
"Ah... mind sharing what?"
"Gotta grab some ovulation drugs."
Yoon Seoyoon flashed a bright smile.
"O-Ovulation drugs...?"
"Yeah. Heading to the adult pharmacy near Futanari Corporation."
"...Ah! Then come with me!"
The blonde beside the black-haired woman who spoke first lit up.
"I'm a member there! Go with me, get a discount!"
"Oh?"
"Yes, yes! So, yeah?"
"Hmm. Sure, why not."
Yoon Seoyoon smiled back.
She wasn't thrilled, but the girl was so insistent it felt rude to refuse—and hey, same kind of female.
If it'd been some dude, she'd have showered him in contempt.
"See you later then."
The black-haired one—apparently a friend—gave an encouraging send-off as she walked away. Yoon Seoyoon watched them go for a moment, then refocused on her workout.
"Everyone's so upfront about it."
The world's biggest prostitution conglomerate had its HQ right nearby—maybe that's why they all seemed so open about sex.
Open? More like fused with it.
"Hee-hee."
Not a bad vibe.
At least here, fewer weird stares at her and her little sister's relationship.
Workout done, gym clothes swapped for streetwear—Yoon Seoyoon headed to the adult pharmacy.
The blonde—Yujia—walked beside her, giggling and clinging tight.
"Teacher Seoyoon."
"Yes?"
"Your boyfriend's really your blood-related little sister?"
Yujia asked with sparkling eyes.
"Of course."
"Gasp! Didn't expect you'd just say it straight...!"
Yujia let out an exaggerated squeal.
Her eyes glittered even brighter.
"Really? Hnnng. Got it."
"Why? Weird?"
"Hmm. Social eyes? Or my personal take?"
"Your personal take."
Yujia gave a small smile.
"I think it's great. Kinda jealous, even."
"Oh?"
"Yeah. You love it, right? What more can I say?"
Yujia glanced away briefly.
"Still..."
Far off, the sky stayed dyed blue, heralding summer's approach.
"Kinda disappointing."
"Disappointing?"
"Yeah. You never seemed into guys. Made me wonder."
She gave a hollow laugh.
"Like, maybe she likes girls. Then I'd have a shot—y'know?"
"...I..."
"Ah, stop there."
Yujia pressed a finger to Seoyoon's lips.
"Don't wanna hear more. Feels like pity then."
"Oh."
"Yeah, that's it."
Her shoulder bumped Seoyoon's.
Seoyoon could almost hear Yujia's heart thumping wildly.
"...We're here."
The adult pharmacy sat midway between gym and company—not far at all.
In front of the door, Yujia hesitated before speaking.
"Hey..."
"Yes."
"Can I hit you up sometimes?"
"Sure."
"But I can't return your feelings."
"Ugh..."
"Friends, though? Totally welcome."
"...Ah."
Yujia's eyes went wide.
She stared blankly at Seoyoon, then burst into laughter.

Right there in front of the pharmacy, in the middle of the street, she laughed till tears welled up—then faced Seoyoon with a relaxed smile.
"Thanks."
Yujia beamed.
Not lovers, but she'd settle for best friends, she told herself.
"Looking for ovulation drugs."
First words out of Yujia's mouth upon entering the adult pharmacy.
"Ovulation drugs?"
"Yes. Ovulation drugs."
"Hmmm. One sec."
The clerk scratched her head and ducked into the back.
She emerged with two types.
"One's straight ovulation inducer. Other's laced with aphrodisiac. Which?"
"Which is better?"
"Both solid. The first..."
Yujia listened to the explanation. A step behind, Seoyoon scanned the shelves.
The drugs looked surprisingly normal.
Mostly pills or powders, some syrups here and there.
Ovulation ones were pills, mainly.
"Hm?"
The clerk paused her spiel as Seoyoon stopped at one.
She approached.
"That one?"
"Yeah. This catches my eye."
"Hng. Can't just pick by looks."
The clerk pulled it from the case.
"This here's livestock aphrodisiac, diluted. Hardcore types go for it."
"...Civilians can buy this?"
"Not the raw stuff—it's like 100x diluted. Fine."
The grimmer the clerk's rundown got, the more Seoyoon's eyes sparkled.
"Wanna test it out?"
By the time the clerk offered a sample syringe, Seoyoon's head was nodding furiously.
