What Does "Good Friends" Mean?
Seo-yoon Yoon stared blankly at the syringe the employee had handed her.
"...It's an injection? Wasn't it pills originally?"
"It usually is pills. But there were some misuse cases, so with the pill version, it takes about one to two hours after taking it for the effects to kick in."
"Hmm. So this one..."
"Reagents need to work right away, don't they?"
Seo-yoon nodded at the employee's explanation.
Yeah, if something called a "reagent" only worked after one or two hours, that wouldn't do at all.
"Ji-ah."
"Yes?"
"Come here for a sec."
Wearing a mischievous grin, Seo-yoon called out to Ji-ah, who was browsing products on the other side of the pharmacy.
"What's up?"
Ji-ah approached with a goofy smile.
Seo-yoon grabbed her arm and jabbed the sharp needle right into it.
"...Huh?"
"Oh my."
Ji-ah wore a dazed expression, not yet grasping the situation, while the employee looked delighted, like she'd just witnessed something fun.
Stoically, Seo-yoon pushed the drug into Ji-ah's arm.
"Wha..."
Joy and sorrow crossed paths.
The employee pulled a bag of popcorn from a drawer under the counter and popped it into the microwave.
"You're used to this."
"Looks can be deceiving—five years on the job."
"A true veteran."
As their brief exchange ended, the drug must have kicked in, because Ji-ah's pupils began to contract.
Pik—red blood trickled from her nose.
"Guh, oh, ooooh...?!"
Sploosh—love juices burst from between her legs.
Her waist twisted, her entire body convulsing from brain-melting pleasure.
"———♥ —♥♥"
Without even a scream, Ji-ah collapsed to the floor, spewing ecstasy.
The employee watched her thrash like a freshly caught fish and pulled out the steaming popcorn with evident enjoyment.
"Want some?"
"Ah, no thanks. I'm trying to watch my figure."
"Mm. Fair enough."
"Great reaction."
"Right? The injection hits all at once, but pills build up gradually in stages."
"Hmm. I like the sound of that."
Ji-ah squirted fluids everywhere, her body jerking in spasms.
Seo-yoon looked down at her, trembling on the floor and emitting sounds that could have been moans or roars.
"I'll take it."
"Oh, thank you. Membership discount?"
The employee gestured toward the quivering Ji-ah on the floor.
"Of course."
"Got it. One moment, please."
The employee set the popcorn on a nearby desk and approached Ji-ah.
"—♥ ——♥♥ —♥"
"Where is it... Ah, here."
"——♥♥♥♥"
The employee pressed her foot gently on Ji-ah's writhing lower belly and rummaged through her pockets.
She pulled out a card, headed to the counter.
"That'll be... with the discount... 120,000 won."
Beep—the payment processed.
Seo-yoon took the drug and glanced down at Ji-ah on the floor.
"Ah, you can leave her. I'll handle the detox."
"...Detox?"
"Well, at this level, it's basically poison."
"Hmmm. Yeah, fair point."
After exchanging some light banter, Yoon Seo-yoon left the pharmacy.
A wet squelch echoed.
Something damp pressed against her back, her heart pounding painfully fast. Her whole body burned hot, her head foggy, like her brain had short-circuited.
"...Uh, eh?"
"Ah. Sis, you're awake?"
"Uh, eh... Wha, what...?! Guh, hngh—♥ Guh—♥♥ ——♥"
Yoon Seo-yoon opened her eyes, her body heavy like she'd just woken from sleep, memories coming in fragmented bursts.
In the onslaught of brain-rattling pleasure, she slowly took in her surroundings.
...Drug bags?
Why were there so many drug bags like that... Ah.
Ovulation drug...
A special version, diluted and refined from the original animal-use formula.
Bags of it were scattered haphazardly under the bed and on the table. Just the torn-open ones in plain sight numbered over three.
Right... I definitely...
-Does one pill do it?
-Hmm. Doesn't seem effective.
-One more?
...Ah. Seo-ha's coming. Qu-quick, one more...!
...Am I an idiot?
She'd seen exactly what happened to Ji-ah from one injection, so what gave her the confidence to swallow three or four pills?
No wonder her body felt so limp, her brain refusing to function properly...
"Uh, eh..."
"Saw the whole thing?"
"...Seo, ha..."
"Yeah, sis."
Yoon Seo-ha's tender hand stroked Seo-yoon's cheek. Her hypersensitive body climaxed instantly from the gentle touch, convulsing.
"Heeek... ♥"
"Why'd you take something like that? I'm curious, but... you don't seem in any state to talk."
"Guh, hngooo... Hiii... ♥"
"Let's wring out all those orgasms and flush the drug? Got it?"
Seo-yoon nodded instinctively to Seo-ha's gentle tone.
Not that defying or resisting Seo-ha was ever an option for her.
Slowly, Seo-ha's hips began to move. Perhaps out of consideration for her just-regaining-consciousness sister, the previously still hips resumed their rhythm.
The vaginal walls, clinging tightly to the cock, begged desperately as it withdrew.
"Ohhh gooood—♥"
Was the drug finally wearing off? At least her moans sounded somewhat human now, far from the beastly howls Ji-ah had made.
Of course, they were still utterly vulgar—but it was impossible not to sound slutty while getting pounded by a futanari cock.
Especially Seo-ha's.
The cock of the sister she loved so deeply she'd even want her child, blood relation be damned. How could anything but a lewd voice escape her lips?
Especially since she'd loved her since her days as a man.
"Hngheeek ♥"
Tasting that brain-shattering pleasure once more, Yoon Seo-yoon surrendered to the onrushing sensations.
Late at night.
Yoon Seo-ha drew the curtains in the living room, where bright moonlight streamed in, and took a sip of tea from a plastic bottle.
"Was that too much?"
Mom or the others might be fine, but maybe it was too intense for her sister.
Mom was a pro-whore for mega-futas, and the rest were futanari like her.
Even if sis had inherited Mom's whore bloodline, maybe it was overkill.
"Ungh..."
"Oh."
That thought shattered as Yoon Seo-yoon recovered quickly and sat up.
As expected of pro-whore lineage.
"Sis, you okay?"
"......Yeah."
A bit dizzy, she leaned against Seo-ha and nodded faintly.
Warmth enveloped her.
"...Why'd you take the drug?"
"Huh?"
"It could be bad for your body."
"It's clinically tested and all, fully approved, right?"
Yoon Seo-yoon rubbed her cheek against Seo-ha's breast as she spoke.
"Still. That much is dangerous."
"......Yeah."
"Why'd you do it? Hmm? Sis."
Seo-ha hugged her tight, her voice full of worry.
Seo-yoon closed her eyes for a moment, burrowing deeper into her embrace.
"I was... a little anxious."
"Anxious?"
"Yeah. Like... you'd just sweep me aside."
Moisture crept into Seo-yoon's voice.
"I'm... the female. With all these other futas, I'm the only real female..."
"You thought I'd dump you?"
"......Yeah."
Her body trembled. Maybe anxiety, maybe joy at being understood.
The conflicting emotions crashed together, birthing feelings beyond words.
"Why would I ever dump you?"
Seo-ha said firmly.
Her arms tightened around Seo-yoon.
"Don't say that."
"But..."
"Sis."
Seo-ha pulled her close, addressing her growing timidity.
"You're my first. That'll never change."
To her, Mom Baek Ha-eun was an object of respect; sister Yoon Seo-yoon, of longing.
Seo-ha had always admired her vibrant, popular sister.
"Hey, sis."
Seo-ha spoke slowly.
"When you said you liked me... I was happy, you know?"
It might've been the first confession she'd ever received.
They say admiration is the emotion furthest from understanding. Why? Because it's usually the lesser looking up to the greater, sharing no common ground.
Thus, incomprehensible.
No shared burdens or circumstances.
"Sis."
That's why Seo-ha no longer merely admired Seo-yoon.
She wasn't just someone to look up to anymore.
"No, unnie."
She was a lover to walk beside, to share the same views.
"I love you."
A bond of pure love, beyond admiration or understanding.
