My Sister-in-Law Is S-Grade Cow

Chapter 2

5,074 words

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 nephew’s mouth.

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

I couldn’t 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-law’s voice rang out.

“Who is it?”

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

“It’s 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.

She’d put my nephew back in his room, asked what I wanted to eat—she’d cook.

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

Thinking she’s the top S-grade in the cow group, I choked.

Emily was my brother’s second wife, kind, gentle, virtuous—no flaws.

But if she’s doing that behind his back, I’ll find evidence and make her divorce my brother!

All sorts of thoughts jumbled my mind.

“There is no need, I’ll go back to sleep.”

She nodded without saying more.

I went to my room, opened my phone—Zach had sent several voice messages.

Clicked the first: Zach still laughing.

“Hey hey, you shy or what? Hahaha, didn’t think you’d be so innocent.”

“I warn you, don’t report it! Heard someone did before—useless, and got a leg broken.”

“Anyway, I haven’t tried yet.” He muttered low.

Then Zach explained: $1,000 for fresh-squeezed to drink, $5,000 definitely direct from the source.

Finally, seeing no reply, teased: “Where’d you go? Couldn’t 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 tips—identical to my sister-in-law’s.

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

Then gritted teeth, transferred $1,000.

Free milk—Zach 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 couldn’t help the quiet task. “She probably doesn’t need more, right?”

Those breasts of hers were already massive, heavy and round, straining every button on her blouse. They looked bigger than my nephew’s head. Any more growth and the fabric wouldn’t 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 wouldn’t 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 wouldn’t be enough tonight.

I needed her. Soon.
