After Masturbation Comes Wisdom, But the Chest Felt Heavy
After jerking off, one becomes wise. But her chest felt heavy.
Black, sticky emotions piled up inside, stacking higher and higher until they seemed ready to overflow at any moment.
Her stomach churned like indigestion, even though she hadn't eaten a thing. The dizzying sensation of a lump right below her esophagus made her head spin.
Heavy, stuffy, dizzy. The more she forced saliva down her throat, the bigger that lump inside grew.
"Feels like I'm gonna puke."
She staggered down the street.
She entered a nearby motel she'd booked on a whim and rode the elevator up.
"Ah, you're here...?"
"...BB."
"Yeah."
Inside the room waited BB, already stripped naked.
Seoha had messaged her the moment she booked the room—how had she gotten there faster?
The gym was closer than the company, sure.
'Guess I was walking that lifelessly.'
Yoon Seoha stared at BB with sunken eyes, then slowly began undressing.
"W-wait, jumping right in?"
"Huh? Why? Problem?"
"No, it's not... that."
BB eyed Yoon Seoha.
Those darkly sunken eyes, that emotionless expression. She'd said she went to her sister's gym—what had she seen there?
'Was unnie with another guy?'
That would definitely hurt.
The pain of seeing your mom-born onahole used by some other man without permission. She'd never witnessed or even heard of it happening, but somehow, a deep-seated revulsion welled up from the bottom of her heart.
"Ah..."
Light thuds echoed. Her black suit hit the floor, and naked Yoon Seoha approached BB.
Her dick stood fiercely erect. Unlike back when she was a virgin, it had grown even more savage after learning the taste of pussy.
"W-wait a sec..."

"Ch-cheating... with a dick like this...?"
Thick veins writhed, sticky precum dripping in heavy globs.
Precum thicker than most guys' actual loads. BB gazed at it pitifully, like it was a waste.
She wanted to lick it up right now—deep-throat it, swirl her tongue around it like candy inside her mouth.
But she held back.
Not instinct or self-control. It was the ingrained mark of her training.
"Ah, ahhh...♥"
"Wanna lick?"
BB's head shook frantically.
"Good girl. Lick it."
"Hauuuwup!"
BB swallowed the 30cm-plus thick shaft in one gulp. It plunged into her gaping esophagus, and she started munching on the pillar with her throat muscles.
Gag reflex kicked in, vomit rising—but her conditioned body ignored it completely. More fitting for words like "living onahole" than bitch or sow.
"Kuheuwup♥"
"That's it, good girl."
"Gruuup♥"
Stroking her head like a dog's, Yoon Seoha looked down at her.
Convenient onahole.
If only she didn't belong to Section Chief Do Yoonseo.
'BB said it's fine... but should you trust a toy's word or the owner's?'
"Maybe I should just ask."
Yoon Seoha grabbed BB's head and shoved her dick deep into the throat. As BB gagged and choked, Seoha picked up her forgotten phone.
[Hello? Seoha?]
"Ah, Section Chief."
[What's up?]
Do Yoonseo's voice came through the line. Was she watching a movie? Foreign voices and faint moans played in the background.
"Can I borrow BB for a bit, Section Chief?"
[Huh? BB?]
"Yeah."
[Ohhh, that's why you're calling?]
A loud laugh burst from the phone. Sounded like she was slapping her thighs—each smack made the background moans louder.
[Sure, go ahead. I'd be pissed if it was someone else, but you? Fine. BB told you already, right?]
"Mm, yeah, but... a tool's word matters less than the owner's."
[Pfft, fully futanari now, huh? Might promote you faster than I thought.]
She let out a small chuckle, then a sultry sound like she was stretching.
[Use her however you want. Just clean her up after?]
"Yes, thank you."
[No biggie. We're past that.]
Hanging up, Yoon Seoha stroked BB's nearly suffocating head.
"Now that I've got the owner's permission..."
She yanked her dick from BB's throat and tossed her onto the bed.
"Kyaaak...♥"
"Rough's okay, right? You're not silicone—you might rip, but whatever."
"Ah, uuuum. G-getting pounded by something that awesome... even if not silicone, I might break...?"
"What're you whining about when you take the section chief's?"
The pink dildo BB had been using. Modeled after Do Yoonseo's dick, apparently. It looked about Seoha's size, and she took it casually—how the hell would she break?
Drama queen.
"Spread your pussy."
"...Y-yes♥"
A wet squelch, and BB's pussy gaped open. A finger with glittering pink nails pried it apart, prepping the twitching hole.
"O, oooh♥"
Pussy meat clenched hard around her. The dick sank in over halfway in an instant, pressing firmly against her womb, and a cheap moan spilled from BB's lips.
Yoon Seoha rocked her hips slowly.
Squelch♥ squelch♥ squelch♥ squelch♥
The wet sounds rang in her ears; each thrust made the walls cling and drag along her shaft.
Squelch♥ squelch♥ squelch♥
"Keu, hiik♥ kuheup♥"
"Squeeze tighter. Yeah, like that. Good girl."
"Keu, hiiik♥ koooook♥"
"That's it, good girl."
Yoon Seoha kneaded BB's lower belly, thumping her womb. BB squirted fluids under the assault, her waist writhing as utterly vulgar moans poured out.
With a glorp, her womb filled with cum, and BB's body shuddered.
A veteran with years at Futanari Corporation under her belt—over a thousand dicks taken—but futanari cocks still didn't get easier.
Lately, faking moans and orgasms was harder than taking dick, but in front of a futanari, she couldn't hold back.
Felt like losing her virginity again. Pussy stretched wide, juices flooding out, womb flooded with semen.
'P-please... knock me up...♥'
Her body—her flesh—craved it.
Craved this futanari's seed.
BB clenched her pussy with all her might. Pure reflex. She sealed her cervix tight, trapping every drop.
"Hooook♥"
"Uuum."
Yoon Seoha frowned and muttered.
"...Glans is caught? Relax."
"N-nooo... c-can't relax...!"
"Hah. Fine then..."

"Take this...!"
"Kuhuoook♥ khiik♥ kuheuwik♥"
"I said relax! You fucking onahole!"
"Khoooook♥"
Seoha grabbed BB's waist and slammed her hips wildly.
BB's trashy tits flopped around; drool spilled from her mouth onto the motel sheets. Sow-like moans filled the room.
Yoon Seoha pumped load after load into her womb.
By the time BB's belly swelled pregnant-full of cum, her body went limp, cervix finally relaxing.
Semen gushed out in thick spurts.
"Fuuu... uuu...."
Yoon Seoha exhaled deeply.
The lump in her chest felt a little digested now.
Yoon Seoha's older sister—no, unnie—Yoon Seoyoon was a shotacon.
Or rather, she had been.
'Not turning me on.'
It was weird.
Bathroom pics of Yoon Seoha, snapped secretly under Mom's watch.
Normally she'd have blown three loads already, but nothing.
'Why?'
Instead, that stunning woman she'd glimpsed through the gym door earlier? Thinking of her got her pussy wet.
"Not getting horny for Seoha?"
No way.
"Eyy, no chance."
Yoon Seoyoon set the photos down.
"Huh. It's been a week already."
She stretched and stood, a lewd sound slipping from her lips as her body cracked.
"Shooting ran longer than expected... wonder if Seoha's waiting."
Her eyes flickered as she gripped the door handle to her private gym room.
"Mm. No way."
Not impossible...
"There are breast enlargement pills out there..."
Yoon Seoyoon glanced at her own massive tits and muttered.
"Guess I gotta meet her."
That unnie. The one who might be her little sister.
