My Sister-in-Law Is S-Grade Cow

Accidentally Stumbling into the Cow Herd Group,

My gentle and virtuous sister-in-law is actually the top S-grade cow in there!

Her job is surprisingly so thrilling!

And my brother has no idea, even urging her to keep taking those supplements.

Seeing her milk cravings gradually intensify, I could no longer hold back

I was playing with my newborn nephew,

when a friend sent me a sleazy emoji, asking if I wanted some milk.

I thought maybe my buddy Zach had a good source,

perfect for buying some for my nephew, so I said sure, send the link.

No link came, but an invite to join a group did.

A QR code for a group called Milk Cow Herd.

I couldnt help but wonder, is it fresh-squeezed?

Out of curiosity, I joined the chat.

While waiting, I asked my friend what kind of milk it was and how the quality was.

Im buying it for my little nephew, quality has to be top-notch!

Unexpectedly, Zach burst out laughing: No way, no way, you really cant tell what kind of milk this is?!

I frowned: Stop teasing, just tell me!

Zach chuckled and dodged: Youll know once you join the group in a bit. Dont blame me for not warning youbetter find a private spot.

Knowing Zachs personality, I figured it wasnt that simple.

Sure enough, after joining, it blew my mind.

I went back to my room, locked the door, and as soon as I entered, a few messages popped up.

A-grade milk is pretty good, fragrant and thick.

Youre new, right? I suggest trying S-gradethat taste is extra smooth, but S-grade is the most expensive.

How expensive?

One cup ten grand, direct five grand? Wait, no0-0,000 a cup, direct $5,000.

Holy crap, but if its as good as you say, its worth it.

What the hell, milk at 0-0,000 a cup? The most expensive formula Ive seen is like 0-000 a can.

0-0,000 a cupthis is sky-high! Scammers!

Just as I was about to leave the group and report it, a chat log was sent.

The group owner @ me: Welcome new friend, check the chat history above for cow photos and prices. Like one, DM me.

I excitedly clicked in, wanting to see what milk was worth more than gold.

What caught my eye was a photo of massive breasts!

Snow-white peaks with a pink pearl right in the middle, a milky white droplet oozing from the tip of the pink pearl, making your mouth water.

I sharp-eyed spotted a small star-shaped tattoo in the cleavage.

This woman is so wild! Tattooing right in the middle of her chest.

Below the photo: S-grade, 0-0,000 a cup, direct $5,000.

Scrolling down, photos labeled A, B, C, D, all kinds.

They were all stunning, but none compared to the first S-grade I saw.

The round, full, perky curve really made you want to grab and knead hard.

Looking at these photos had my face flushing, heart pounding, swallowing saliva repeatedly.

I quickly called Zach; he seemed to be waiting, picked up in a second.

What the hell are you playing at?

My voice was trembling, body getting hotter, my lower half tightening as expected.

Zach let out a wicked laugh: Hahaha, hows that? From your voice, I know youre satisfied.

I was about to curse him out for this messed-up stuffgetting caught would be fun in jail.

Then a door-opening sound came from outside, my heart jumped to my throat, I hung up immediately.

I suddenly rememberedI came home specifically to see my newborn nephew, hadnt told my brother yet.

Hope they didnt hear?

In that moment, a sucking sound came from outside, seemed like in the living room.

I held my breath, cracked the door to peek.

From the crack in my door, I saw a woman on the sofa across the hall.

Her body curved in a perfect S shape. She cradled my newborn nephew in her arms.

His tiny mouth latched onto her pink nipple. He sucked steadily. Each pull made her full, pale breast lift and fall in a slow, hypnotic rhythm.

My gaze drifted lower without permission. Lingering on the soft swell. The way her skin flushed warm under his feeding.

Then recognition hit. This was my sister-in-law.

Heat flooded my face.

I jerked back from the door. But my ears still burned. Pulse loud in my head.

Something tugged at memory. I leaned forward again. Peeked carefully.

My eyes fixed on her cleavage. There it was. A small star-shaped tattoo nestled right in the center.

My stomach dropped.

It matched the tattoo on the S-grade cow from the group photos. Exact spot. Same delicate lines.

The curve of her breasts rose identical to those pictures. Full. Firm. Perky in the same impossible way.

Skin so smooth it begged to be touched. Nipple still glistening from my nephews mouth.

A sharp ache twisted low in my gut. Desire mixed with shock.

I couldnt tear my eyes away. Every gentle bounce as she shifted sent a jolt through me.

While I stood frozen, my phone rang loudly. The sound shattered the quiet. My heart slammed against my ribs.It was that idiot Zach!

I panicked trying to silence it, then my sister-in-laws voice rang out.

Who is it?

I turned off the phone, cleared my throat, and shouted out.

Its me.

Ethan? You came back without saying anything.

I awkwardly replied: Too tired, came to see the little guy and fell asleep.

Opening the door, my sister-in-law had already dressed, though a few drops of liquid still lingered on her jeans, unwiped.

Shed put my nephew back in his room, asked what I wanted to eatshed cook.

She wore tight jeans outlining perfect curves, a white blouse stretched to the limit by two massive melons, like theyd burst any second.

Thinking shes the top S-grade in the cow group, I choked.

Emily was my brothers second wife, kind, gentle, virtuousno flaws.

But if shes doing that behind his back, Ill find evidence and make her divorce my brother!

All sorts of thoughts jumbled my mind.

There is no need, Ill go back to sleep.

She nodded without saying more.

I went to my room, opened my phoneZach had sent several voice messages.

Clicked the first: Zach still laughing.

Hey hey, you shy or what? Hahaha, didnt think youd be so innocent.

I warn you, dont report it! Heard someone did beforeuseless, and got a leg broken.

Anyway, I havent tried yet. He muttered low.

Then Zach explained: 0-0,000 for fresh-squeezed to drink, $5,000 definitely direct from the source.

Finally, seeing no reply, teased: Whered you go? Couldnt handle it and went to jerk off?

I twitched, cursed: You jerk off!

Ignored him after, reopened the group, found that photo again.

The round curve, pink tipsidentical to my sister-in-laws.

To confirm if S-grade was her, I messaged Zach to book S-grade, record the squeezing process.

Then gritted teeth, transferred 0-0,000.

Free milkZach happily agreed!

Soon Zach said booked, time tomorrow 3 PM.

Evening, my brother came home.

I looked gloomy, not knowing how to speak.

Darling, remember to take the supplements I bought.

My brother set the fancy bottle on the table, eyes soft on Emily.

I couldnt help the quiet task. She probably doesnt need more, right?

Those breasts of hers were already massive, heavy and round, straining every button on her blouse. They looked bigger than my nephews head. Any more growth and the fabric wouldnt stand a chance.

Truth was, my brother looked worn out. Thinner since last time. Cheeks hollow. He was the one who needed boosting.

He waved me off. You wouldnt understand. I let it drop.

Later that night, fresh from the shower, I collapsed on the bed. Phone lit up. Video from Zach.

S-grade teaser, he wrote.

I hit play.

Pink sheer lingerie clung to her body. Thin fabric hid nothing. Full breasts swayed with every slow twist of her hips. Nipples dark against the pale material. Hard. Begging attention.

She moved closer to the camera. Breath hitching audible.

One hand slid up. Fingers hooked the strap. Pulled it down.

A perfect breast spilled free. Heavy. Glistening at the tip with a bead of milk.

She cupped it from below. Lifted. Squeezed gently.

The pearl-hard nipple pointed straight at me. Another drop formed. Swelled. Fell.

Her soft moan filled my ears.

She pushed the breast toward the lens. Closer. Closer. Until the screen was nothing but soft, wet skin.

Video cut to black.

Heat slammed through me. Cock throbbed hard against my thigh.

I pictured Emily in that lingerie. Those same full tits in my hands. Milk warm on my tongue.

Imagined pinning her down. Sucking until she gasped my name.

Tomorrow Zach would taste her for a thousand bucks. Direct from the source.

Jealousy burned hot. Mixed with raw want.

My hand moved down without thinking. Gripped tight.

One stroke and I knew a cold shower wouldnt be enough tonight.

I needed her. Soon.

Next day, 2 PM.

I reminded Zach to recordfor evidence to show brother.

But this guy no reply till 2:30.

Seeing sister-in-law already out, I was antsy like on hot coals.

Damn! Unreliable at crucial moment!

Called Zach frantically, finally connected at 2:45.

Zach weakly said he couldnt gogot hit by a car just leaving.

What the hell, such coincidence??

Clenched fistonly me then.

Alright bro, rest; Ill visit after.

Wait

Hung up, vaguely heard two words before disconnect.

But anxious to reach by 3, ignored.

Arrived exactly 3:01 at the door.

Rushed, just threw on mask and sunglasses.

Hope not recognized.

Nervous, rubbing hands,

rang doorbell.

After a while, door opened.

It was sister-in-law Emily.

I lowered eyes disappointed.

My brother treats her well, buys expensive supplements without question.

Plus, hes a factory owner, good salary.

If in trouble, tell himwhy do this?

But in a flash, hid emotions, stared straight at Emily.

She wore last nights pink sheer, with her gentle calm facemade you want to hurt her bad.

Wearing so littlenot afraid clients go further while drinking??

Mr. Zach, not coming in?

Sister-in-law unconsciously rubbed shoulders, her two melons squeezed together by arms.

Her scent filled my nose.

Entered, Emily pulled a black blindfold from bag, covered eyes.

Sat on bed, lifted one side, exposed full melon.

Mr. Zach, I know you dont want face seenI blindfolded, come quick!

Huh?

Her actions stunned me.

Isnt 0-0,000 just one cup?

Her poselike ready for direct mouth.

She hesitated: Mr. Zach, your $5,000 allows direct

Suddenly, she smirked, grabbed me to bed, flipped and straddled.

Zach, dont be shy.

Once, therell be twice.

Im amazing.

She cooed, leaned down.

Before I spoke, mouth blocked.

Felt soft skin spreading over body, instinctively gripped her slim waist, making Emily moan.

The big thing in mouth kept pushing in.
