Don't Stare, Just Snap – Dripping Gym Debut
Don't look, just take the picture quick. It's gross.
Early morning.
Yoon Seoha rose from the bed, rubbing her sleepy eyes as she shuffled out of the room.
She flicked on the lights in the dark hallway and living room, then ran her fingers like a comb through her tangled hair on her way to the bathroom.
Having woken up naked, she was spared the hassle of undressing—small mercies.
Inside the bathroom, she turned on the shower. Warm water cascaded down immediately, soaking her hair first and then her body.
As the hot stream thawed her out, she brushed her teeth, rubbing her eyes again. The gunk flaked away, and focus sharpened in her once-blurry gaze.
"Ptooey."
She spat the foam onto the floor, rinsed her toothbrush, and hung it back on the rack.
There were four toothbrushes: Mom's, Dad's, her older sister's, and hers.
Mom was away on a business trip with zero contact. Dad had gone radio silent for three or four months now—at least with her. He was still talking to Mom, apparently.
Come to think of it, that cop... does she know Mom?
Mom never blabbed about work, and Seoha never went out, so she knew zilch about her colleagues.
"Nah, probably not."
The fleeting suspicion sank away.
For starters, the uniforms were totally different.
Mom's was a proper police getup. That other one had been customized so many times it looked like straight-up sex cosplay—no common ground there.
Hell, it wasn't even clear if it was real police attire.
"Nngh?"
"...Oh, Seoha."
"You up?"
The door creaked open. A rush of cool air made her shiver for a second.
Stepping into the bathroom was her older sister, Yoon Seoyoon—looking utterly exhausted compared to Seoha. Her hair was a dry, frizzy mess, dark circles heavy under her eyes, her body covered in kiss marks, bite marks, and scratch lines. Dried pussy juices and cum crusted her lower belly and inner thighs.
"Didn't sleep a wink?"
"Y-you do this to me and ask that...? Whose fault is it...?"
"Pfft, yeah, guess so?"
"Haaah, seriously..."
Seoyoon sighed at her little sister's playful grin and approached.
Maybe her sister being too gorgeous was the problem.
Sure, other guys swarming her was inevitable as the superior stud. But all the annoyance and anger vanishing at the sight of that face? Kinda messed up.
Genes are OP.
Same bloodline, yet looks that put her to shame. Staring at that face sometimes made her self-love evaporate.
Did her genes change when she became a futanari?
Would that make incest legal?
"Haaah..."
A whirlwind of thoughts in her head scattered as she melted into her sister's embrace.
Somehow fully erect already, that dick pressed firmly against her belly—the very culprit that had ravaged her womb mercilessly last night.
"Hauuup."
Squatting down, she wrapped her full breasts around the shaft and softly engulfed the protruding glans with her lips.
Teasing the head inside her mouth with her tongue, she urged it to cum.
Squeezing the pillar between her soft tits, she slurped lewdly at the tip.
"Heeup."
"Good girl."
Seoha's hand settled on her head, stroking gently.
At the petting, Seoyoon climaxed lightly and massaged the dick even more fiercely.
"Huuuup... ♥"
Blurbledurp—thick semen flooded her mouth. Even after all that shooting last night, its density still blew her mind.
Semen packed with impregnation intent, like "failed fertilization" wasn't even possible. Way thicker than anything from other guys—or even porn.
Never seen cum this thick in vids...
Struggling to swallow the globs clinging to her throat, Seoyoon gazed up at her sister with hazy eyes.
Ah... seriously. Too happy.
Happy to be Seoha's sister.
She'd always been happy, but lately? Blissfully to the point of death.
Onahole this, impregnation sack that—didn't matter. Just being used by her sister filled her with joy; getting kissed was pure ecstasy.
Even during workouts or filming, her mind was nothing but filthy thoughts.
She was shocked sometimes at how slutty she'd become, but Seoha loved her even like this.
"Seoha."
"Yeah?"
"Impregnate me."
"Pfft, now you say it?"
Seoyoon let out a light chuckle at Seoha's words.
Fair enough—kinda funny at this point.
She'd been her exclusive onahole for days, bodies entwined nonstop, creampied in pussy and womb.
No condoms, no birth control.
The only pill she popped was an ovulation booster.
"Yeah, true."
So this was normal talk.
Like lovers saying "I love you"—perfectly natural.
"Still wanna say it."
"Oh?"
"Yeah. I want you to knock me up, Seoha. I want your baby."
"Incest sex that good? Naughty sis."
Seoyoon shook her head at Seoha's tease.
"No."
"Huh?"
"It's not the incest—it's sex with you that's good."
"Eh?"
Lust-glazed eyes looked up at Seoha.
"I'm your exclusive breedable onahole, so until you head to work..."
Her voice, brimming with love, echoed through the bathroom.
"Use me lots ♥"
Right in the heart of Seoul stood the gym.
A nationwide chain frequented by world-famous bodybuilders and athletes, and the brand they swore by. That's where Yoon Seoyoon clocked in for work.
Trainer and fitness YouTuber extraordinaire.
Over two million subscribers, skyrocketing thanks to her sharp wit, stunning looks, and pro-level knowledge. She was the gym's poster girl, everyone's first crush.
Men, women—didn't matter. Everyone harbored feelings for her.
"Ah, Instructor Seoyoon! You're here!"
"Yup~ Hello~!"
Women members and staff swarmed her on arrival. Greeting them, Seoyoon radiated an odd erotic aura.
A strange scent wafted from her body. Perfume? It was flushing faces all around.
"Sniff sniff... Instructor, new perfume?"
"...Huh?"
"No, just... smells nice..."
"Ahh... yeah, whatever."
She wore a knowing expression.
That subtly sexy face drew baffled murmurs from some staff.
"Seoyeon."
"...Ah. Seongjun."
A trainer approached from afar.
Kim Seongjun—the guy topping every "hottest at the gym" list. An insurmountable wall for his legions of admirers pining for Seoyoon.
"...Perfect timing. I needed to talk to you too, Seongjun."
"Uh?"
A nearby female member let out a dumbstruck noise.
Normally, Seoyoon was an iron wall with him.
"Wh-what's up?"
Seongjun was flustered too.
"My little sis got me new workout clothes. Take some commemoration pics?"
"Ah, uh... Yeah! Of course!"
Seoyoon eyed his flustered flailing coldly, then headed to the wall and started stripping off her outer layer.
"Hup...!"
"Hm?"
Swallows and murmurs rippled around.
"S-Seoyoon."
"Yes?"
"D-did you... come from home like that...?"
"Huh? Obviously?"
Her tone implied why ask the obvious? Seongjun squeezed his eyes shut.
She called this "workout clothes"? It was basically naked. He grappled with unnamed emotions.
Anger? Despair? What the hell was this?
And why show it off to them?
Questions swirled.
"...Ah."
Drip—something white and thick splattered the floor.
From between her thighs.
...Cum?
It was semen.
Thicker than the creamy stuff in Western porn—way denser.
"Seongjun."
"Y-yes?"
He looked up at her call. Seoyoon glared, looking mildly pissed.
"Gonna take the pics quick? Gotta report back to my sis."
"...Y-yeah."
Grabbing her phone, he opened the camera.
...Ah.
Bottom left of the screen: the latest photo thumbnail.
Flesh tones filled it, searing into his brain.
Curiosity burned. He itched to open the gallery, see what else was there.
But he couldn't.
No guts to open Pandora's box.
"Hurry up and shoot. Don't creepily ogle it."
Click click.
Only the quiet shutter sounded.
