The Lactating Cow Girl, Yang Ara
I let out a soft moan of pleasure. “Mmm♡ Something keeps sloshing around deep inside me… it’s so ticklish…♡ My chest feels so heavy underneath… my nipples feel so heavy…♡”
Besides the Erogenous Zone Development item I’d prepared for today, I had one more ready to go. The maddening itch must have been driving her wild, because Yang Ara began rocking her hips back and forth on her own. The combined range of my thrusts and her movements made her thighs and ass slap together with violent, wet smacks every time we collided.
Slap! Slap! Slap! Slap! Slap! Slap!
“Doesn’t this feel… exactly like we’re having sex…?”
“Ah♡ Ah♡ Ah♡ N-no… this, this is… just masturbation…♡”
“Haa… haa… Right? Sex between close older sister and younger brother is wrong, but helping each other get off with our bodies is okay, isn’t it?”
“That’s right… Masturbating with Junyoung’s cock… feels so good…♡”
Ah… Her thighs are so soft… her breasts are so lewd… and this older sister is so cute… Fuck, she’s insanely hot. Seriously…
“Aah♡ My clit, my pussy, my breasts… everything feels so weird…♡ My breasts are so ticklish… it’s so frustrating… Squeeze them harder…♡”
“Haa… haa… Noona, I’ll milk you… I’ll milk those massive cow tits like crazy…!”
“Milk me…♡ Milk my tits…♡”
The sensation of those plush thighs combined with the utterly obscene sight sent my climax surging forward. I gripped her breasts hard enough to make them deform and slammed my hips with brutal force.
Smack! Smack! Smack! Smack! Smack! Smack! Smack! Smack!
“Noona, I’m gonna cum…!”
“I’m cumming too… I want to cum with you…♡”
I pressed my waist tightly against her body and squeezed her breasts with all my strength, yanking them forward.
“Huuuup…!”
[Cow Syndrome]
A fictional condition where a non-pregnant woman continuously produces breast milk.
Spluuuurt— Splurt, splurtsplurt, spluuuurt—
“Hek♡ Heeeeeeeeek♡”
Yang Ara, still braced against the wall with her upper body bent forward, dropped her head completely. Thick ropes of semen shot from my cock with terrifying pressure, splattering heavily across her enormous breasts.
Cumming in this position and painting her tits completely… it was insanely erotic.
Spluuuuur— Splurt, spluuurt— Fsssh— Fsssh—
While we were both spraying messy fluids from between our legs, a sudden wet sound rang out.
Splaaash—
“A-ahhhhhh♡ Haaaaaaaah♡”
Warm liquid sprayed wildly over the hands I had wrapped around her nipples. Yang Ara’s upper body trembled violently with overwhelming ecstasy.
Splaaaaash—
“Haaaaah♡ It’s coming out♡ From my breasts♡ It’s coming ouuuut♡”
I pulled my hands away from her chest. Even so, her gravity-defying breasts continued to gush milk endlessly.
“Hah♡ Haah♡ Aah♡”
“Huuu…”
After enough time had passed for both of us to ride out the aftershocks of our orgasms—
Splaaaaash—
“A-ah…♡ J-Junyoung… my breasts are way too sensitive right now… stop tickling them…♡”
“I’m not even touching your breasts though?”
“…Huh?”
I was currently hugging her waist and belly from behind, leaning my weight against her back. Another spraying sound echoed.
Splaaaaash—
“Eh…?”
Sensing something strange, Yang Ara looked down at the floor, which was now covered in a large puddle of white liquid.
“W-what…?”
There was my semen, of course, but mixed with it was something clearly different—a milky-white substance pooling on the floor. And even now, the puddle was spreading wider in real time.
She turned her gaze to her own breasts.
“W-wait… what…?! Whaaaaat?!”
“Whoa…”
From her nipples, breast milk was gushing out like water from a sprinkler.
[The condition of producing breast milk without being pregnant is known as Cow Syndrome.]
[Cow Syndrome is a socially stigmatized illness, comparable to a sexually transmitted disease.]
[If Kim Junyoung says so, the illness can be cured.]
[All treatment and management of the illness is to be left entirely to Kim Junyoung.]
[Do not doubt any words Kim Junyoung speaks regarding treatment.]
[As the saying goes, “There is no dutiful son in front of a long illness.” Caring for someone with Cow Syndrome is an incredibly difficult task.]
“Hic… sob… Huuuung… ugh…”
Yang Ara, leaning against me inside the hot bathtub, burst into loud sobs.
“Noona… stop crying. You’re going to exhaust yourself.”
“Hic, sob… This can’t… hic! This can’t be happening… Why… why is this happening to me… huuuung…”
I buried my nose in her trembling neck and wrapped my arms around her waist and shoulders, holding her tight. Her body, warmed by the hot water, felt incredibly soft, and her L-cup breasts floated strangely on the surface, but I had to suppress my lust here.
“Hic… ugh…”
After holding her for a long time, Yang Ara slowly began to calm down.
“Junyoung… hic! The bathwater… it’s getting dirty because of me…”
White liquid was leaking from the tips of her floating L-cup breasts, turning the bathwater cloudy.
“It’s not dirty at all, Noona.”
I gently stroked the area around her areolas and nipples.
“A-ah… Why… why don’t you think it’s dirty…? I’m leaking breast milk…”
“How could anything that comes from Noona’s body be dirty? No matter what other people say, I’m on your side.”
“Aah…”
Yang Ara began crying again.
“Don’t cry.”
I wiped her tears and stroked her shoulders while still holding her. Right now, when she was emotionally devastated, my embrace was probably warmer than the heated bathwater.
“Thank you… thank you so much… my sweet little brother… our Junyoung… thank you… huuuung…”
With this, the first-stage hypnosis I’d planted would become even more solid. From now on, she would depend on me almost like a slave. She would cherish me more than anyone else in the world.
“Noona. I’ll help you.”
[If Kim Junyoung says so, the illness can be cured.]
“Eh…?! R-really…? Ah…”
Her face briefly brightened with hope before sinking back into gloom.
[As the saying goes, “There is no dutiful son in front of a long illness.” Caring for someone with Cow Syndrome is an incredibly difficult task.]
“No… I can’t burden you… I can’t do that to a kind boy like you… As your older sister… this… this isn’t right…”
“I said I’ll help you.”
“B-but still…”
[If Kim Junyoung offers to help, do not refuse.]
I turned her body so she was facing me.
“Noona.”
My rock-hard erection rested against her pubic mound, the tip of my glans pressing against her belly button. But it was fine. To her, my erection was nothing more than a natural physiological reaction.
“Between us, there’s no such thing as burden. If you need help, I’ll help. I’ll stay by your side until your illness is cured.”
“A-ah… You…”
I pulled her shoulders and drew her into my embrace. Her massive L-cup breasts squished firmly against my chest.
“N-no…!”
Yang Ara suddenly pulled away in panic.
“You’ll… you’ll get my dirty stuff on you…”
Like a guilty puppy, she fidgeted anxiously and hugged her own breasts. Milk spurted out with a wet squirt from her squeezed tits.
A married woman hugging her L-cup breasts, skin glistening with moisture, milk constantly leaking out… ‘Holy shit… she’s so beautiful… and so fucking hot…’
I spoke as if it were nothing. “Why did you stop hugging me? Come here. Hug me. I want to be held by you, Noona.”
“Ah… aah… Junyoung…!”
With tears glistening in her eyes, Yang Ara threw herself into my arms.
“Huuuung… huuuuuung…”
She wailed even louder than before. From this angle, Yang Ara couldn’t see my face. A wicked smile I had been holding back rose naturally to my lips.
‘Perfect.’
This lovely cow was now completely mine.
“Huuuung…”
I stroked her slender shoulders while rubbing my cock against the soft sensation of her breasts pressed against my chest.
I had never met Yang Ara’s husband before. He ran his own business and was rarely home, so our paths had never crossed. Before the three of us met, the moment I saw him I immediately applied modifications.
[The condition of producing breast milk without being pregnant is known as Cow Syndrome.]
[Cow Syndrome is a socially stigmatized illness, comparable to a sexually transmitted disease.]
[Producing breast milk without being pregnant is disgusting and repulsive.]
[The mere smell of milk makes you want to vomit.]
[If this matter spreads, my own social reputation will be severely damaged.]
[Do not find it strange that Kim Junyoung is stepping up to treat Yang Ara.]
[Completely entrust Yang Ara’s treatment to Kim Junyoung.]
“What the hell have you been doing with your body?!”
“H-h-honey…? What are you saying… like that…”
She must have held onto a sliver of hope because I had treated her warmly. But that hope was pointless. Yang Ara, you must belong only to me.
Her husband seemed to realize he had misspoken and flinched at his wife’s reaction.
“N-no, what I meant was…”
Right then, as if by accident, he elbowed the side of Yang Ara’s breast beside me.
Squiiirt—
Milk sprayed out, slightly wetting her clothes.
“Aah…”
“Ugh…!”
[Producing breast milk without being pregnant is disgusting and repulsive.]
[The mere smell of milk makes you want to vomit.]
Her husband grabbed his nose and staggered back in horror.
“H-h… honey…!”
Yang Ara was so shocked by her husband’s reaction that she couldn’t even speak.
“I-I’ll go back to work… Just… just try to do something about that for now…”
“Honey… Honey… don’t go… please stay with me… please…!”
“F-for now, just deal with that milk smell by yourself and we’ll talk later! Got it? J-Junyoung, was it? Please take good care of my wife! We’ll greet each other properly next time! Something urgent came up!”
Her husband bolted for the front door.
“Honey! Honeyyy!!”
Yang Ara’s legs gave out from the emotional shock. She couldn’t even chase after him and flailed helplessly on the spot like a newborn foal.
I quickly pulled her into my arms.
“Huuuuuuung!! Uuuuung…! Huuuuuung…!!”
She sobbed bitterly against my chest. I was genuinely worried she might lose her voice.
“Huuuung…! I… I never thought even he would react like that… I thought at least he… at least he… huuuuuung…!!”
Even I was a little surprised this time. I’d heard he was a devoted husband, but I hadn’t expected such a violent reaction.
Skip Men
A passive skill that significantly increases the success rate and strength of modifications applied to male targets.
‘The skill effect really is reliable.’
It had played a big part when I modified Min Chaeseul’s husband too.
“You still have me. Don’t worry.”
“Huuuuung…!!”
That day, Yang Ara cried herself to exhaustion and fell asleep.
After that, the care for her Cow Syndrome began in earnest. To make things run more smoothly, I added a few more concepts.
[You will not milk yourself. Only Kim Junyoung is allowed to milk your breasts.]
[Every time Kim Junyoung milks you, you will feel intense sexual pleasure.]
[You do not find your own breast milk dirty.]
The first two were devices to make her dependent on me. The third was added because she seemed to view her own milk as filthy. After all, I absolutely had to see her sucking her own milk from her own breasts.
“To treat Cow Syndrome, we need to keep draining the milk. I’ll do it for you.”
“D-drain it… you mean…”
“I’ll either squeeze it out with my hands or suck it out with my mouth.”
“Uwaaaah…!”
Yang Ara blushed furiously and covered her reddened face with both hands. I had already touched and sucked her breasts, fucked her, and even came inside her. Yet the act of drinking her milk seemed to strike her as something entirely new.
“Don’t think of it strangely. It’s just treatment, right?”
“Y-yeah… that’s true…”
I sat her facing me on my lap, like we were in a face-to-face cowgirl position. Then I lifted both of her breasts.
‘Wow… they’re seriously heavy.’
They seemed even heavier than before. Was it because of the added weight of the milk?
I had planned to squeeze one with my hand and suck the other, but that clearly wasn’t going to work. They were too heavy, too big, and too soft for one hand to support even one of them.
I lifted one breast with both hands. It was still incredibly heavy.
“…Noona, don’t your breasts feel even heavier than before?”
“Ah…! Right? I was feeling that too.”
The added weight only made them more arousing. The moment I lifted them, milk began leaking from her nipples. I opened my mouth wide and took one breast in.
“Hamu.”
