MY ALPHA STEP BROTHER HIS MY MATE

Chapter three the hunger that follows me

C

I walked into Blackthorn Academy like I was stepping onto a battlefield.

My uniform skirt felt shorter than usual, the pleats brushing against thighs still sticky from Kai’s c*m. Every step sent a fresh trickle of it down my skin, warm and filthy, reminding me exactly who I belonged to now. The bite mark on my neck throbbed under a pathetic layer of concealer and my hair. I’d tried to cover it, but the dark purple bruise peeked through like a brand. His brand.

Girls stared. Of course they did. The queen bees of the senior class Lila Montgomery and her squad of perfectly glossed lips and shorter than regulation skirts were already clustered by the fountain, eyes narrowing the second I passed.

“Who’s the new girl with the hickey?” one of them whispered loud enough for me to hear. “Looks like she got mauled by a wolf.”

I kept my head down, backpack clutched tight, heart hammering. Pretend you don’t know me, Kai had said. But how the hell was I supposed to pretend when my p***y still ached from the way he’d knotted me last night? When I could still taste him on my tongue?

The bell rang. I slipped into my first class English and dropped into a seat at the back. Kai was already there, sprawled in the row behind me like he owned the room. His blazer was unbuttoned, tie loosened, golden eyes locked on the back of my neck like he could see straight through my hair.

I didn’t look at him. I couldn’t. Not when every girl in the room kept shooting him flirty little smiles and “hey, Kai” whispers. He didn’t answer any of them. Just stared at me.

By third period, the whispers had turned into stares. Lila cornered me at my locker between classes, flipping her blonde hair like she was in a movie.

“New stepsister, huh?” she said, voice dripping fake sweetness. “Heard you moved into the Voss mansion. Must be nice living with the Kai Voss. Try not to get too attached, sweetie. He doesn’t do repeats.”

I forced a smile. “I’m not interested.”

She laughed like I’d told the funniest joke ever. “Good. Because he’s mine. Everyone knows it.”

I wanted to tell her he’d already ruined me for anyone else. That his c**k had stretched me open and filled me so deep I still felt him hours later. Instead I just nodded and walked away.

Lunch came too fast.

I was heading toward the cafeteria when a strong hand wrapped around my wrist and yanked me sideways into an empty classroom. The door slammed shut. Lock clicked.

Kai.

He spun me around and shoved me up against the whiteboard, my back to his chest, his massive body pinning me there. One hand clamped over my mouth before I could gasp.

“Been hard for you since breakfast,” he growled against my ear, voice rough with the shift. “Watching you try to hide my mark. Watching you walk around with my c*m still leaking out of that pretty cunt.”

His other hand shoved my skirt up and ripped my panties down in one brutal tug. I heard his zipper, felt the thick, hot length of him slap against my ass.

“Kai wait someone could enter”

He didn’t wait. He bent me forward over the teacher’s desk, kicked my legs apart, and slammed into me in one savage thrust.

I screamed into his palm. The stretch burned so good, his c**k bigger than I remembered, dragging against every sensitive spot inside me. He f****d me hard and fast, hips slapping against my ass, the desk creaking under us.

“Quiet, mate,” he snarled, teeth grazing the bite mark on my neck. “Or do you want the whole school to hear what a slutty little stepsister you are?” He pulled almost all the way out, then drove back in deeper, grinding the swelling knot against my entrance. “This p***y is mine. Say it.”

I moaned against his hand, nodding desperately as he pounded into me. My t**s were smashed against the desk, n*****s hard and aching. Every thrust pushed me closer to the edge, wet sounds echoing obscenely in the empty room.

He yanked my hair, arching my back so his mouth could reach my ear again. “Gonna knot you right here. Fill you so full you’ll be dripping through your next class. Let them smell me on you.”

The knot swelled fast thick, hot, stretching me impossibly wide as he locked us together. I came violently, walls fluttering and squeezing around him, vision whiting out while he roared low and deep. Hot jets of c*m flooded me, pulse after pulse, so much it leaked out around the knot and ran down my thighs.

He kept grinding against me through it, milking every last drop, teeth sinking into my shoulder just hard enough to leave another mark.

When the knot finally eased, he pulled out slowly, watching his c*m spill from my swollen p***y with a satisfied growl. He scooped some up with his fingers and pushed it back inside me, three thick digits f*****g it deeper while I whimpered.

“Keep it in,” he ordered, voice dark. “All day. Every time you feel it drip, remember who owns this cunt.”

He fixed my skirt, kissed the fresh bite on my shoulder like it was a promise, then unlocked the door and slipped out like nothing had happened.

I stayed there for a minute, legs trembling, trying to catch my breath. My phone buzzed.

A text from an unknown number probably one of the girls.

Saw you go into that classroom with Kai.

Everyone’s talking. Better watch your back, new girl.

My stomach dropped.

But between my legs, I was already getting wet again.

Because Kai wasn’t done.

And neither was I.
