Knot Me, Stepbrother

5: Snapped

Reagan’s grip on my arm was still tight as he spun me around to face him. His chest heaved, eyes glowing bright gold with barely contained fury and something much darker. The scent of my heat filled his room instantly, thick and sweet, wrapping around both of us.

“You think I’m going to let those bastards near you?” he growled, his voice was rough and low. “You think I’m going to stand there while they talk about knotting my little stepsister?”

I tried to pull away, my body trembling from the heat and his touch. “You said you didn’t want me. You told me to find someone else. You called me disgusting...”

Reagan’s hand moved to my other arm, holding me in place. His eyes dropped to my chest, where my ample breasts strained against my thin shirt, n*****s hard and obvious. I was skinny everywhere else...narrow waist, slim hips...but my breasts were full and heavy.

“Shut up,” he snarled. “You have no idea what you’re doing to me.”

Before I could respond, he backed me up against the wall. His mouth crashed down on mine in a brutal kiss. It wasn’t gentle. It was angry, hungry, and desperate. His tongue pushed past my lips, claiming my mouth as his hands moved to my waist, gripping hard.

I moaned into the kiss, the heat making me melt against him. My virginity made everything feel sharper, more overwhelming. I had never been touched like this.

Reagan broke the kiss, breathing hard. His eyes were wild. “This is wrong. So f*****g wrong. But I can’t… I can’t let anyone else have you.”

He dropped to his knees in front of me, yanking my shorts and panties down in one rough motion. Cool air hit my soaked p***y and I gasped.

“Reagan...”

“Quiet.” He spread my thighs with strong hands and buried his face between my legs.

The first swipe of his tongue over my swollen c**t made my knees buckle. I cried out, hands flying to his hair. He licked me like a starving man...long, firm strokes from my entrance to my c**t, sucking the sensitive bud into his mouth. His growls vibrated against me, sending shocks of pleasure through my virgin body.

“Oh god… Reagan…” I whimpered, hips rocking against his face.

He sucked harder, tongue flicking fast, then pushed two thick fingers inside me. The stretch burned a little, but the heat made me so wet that they slid in easily. He curled them, hitting a spot that made stars burst behind my eyes.

“You’re so f*****g tight,” he groaned against my p***y. “Virgin little cunt dripping for your stepbrother.”

I came hard within minutes, thighs shaking around his head as waves of pleasure crashed over me. He didn’t stop. He kept licking and sucking through my orgasm, drawing it out until I was sobbing with overstimulation.

When he finally pulled back, his mouth and chin were shiny with my slick. He stood up, towering over me, and ripped my shirt off. My big, ample breasts bounced free. Reagan’s eyes darkened with pure lust.

“f**k… look at these tits.” He cupped them roughly, thumbs brushing over my hard n*****s. “So big and pretty on such a skinny little body.”

He lowered his head and sucked one n****e into his mouth, hard. I cried out, back arching. He switched to the other, sucking and biting gently while his hands squeezed the soft flesh. My breasts were sensitive, and every pull of his mouth sent jolts straight to my core.

Reagan straightened, breathing ragged. He shoved his sweatpants down, freeing his massive c**k. It was thick, long, and already leaking precum. The knot at the base was already starting to swell slightly.

“You’re really going to let your stepbrother take your virginity?” he asked, voice dark. His hand wrapped around his c**k, stroking once. “Say it.”

I was shaking, heat making me desperate. “Please… Reagan. I need you.”

He lifted me easily, my skinny frame was weightless in his strong arms, and carried me to his bed. He laid me down and climbed over me, spreading my legs wide.

“This is going to hurt at first,” he warned, pressing the thick head of his c**k against my entrance. “But you’re going to take every inch like a good little sister.”

He pushed in slowly. The stretch was intense...burning, full, overwhelming. I cried out, nails digging into his shoulders as he breached my virginity. Blood mixed with my slick, but the heat helped me take him. Inch by thick inch, he sank deeper until he bottomed out, his heavy balls resting against me.

“f**k… so tight. Virgin p***y squeezing my c**k so perfectly,” he groaned, staying still for a moment to let me adjust.

Then he started moving.

Slow at first, deep thrusts that made my ample breasts bounce with every stroke. He leaned down and sucked on my n*****s again, alternating between them while he f****d me harder.

The pain faded fast, replaced by blinding pleasure. I moaned loudly, legs wrapping around his waist.

Reagan’s pace quickened. He f****d me deep and rough, the sound of skin slapping skin filling the room. “This is what you wanted, isn’t it? Your stepbrother’s c**k ruining your virgin cunt.”

He flipped me onto my hands and knees, gripping my slim hips and slamming back inside. One hand reached around to rub my c**t while the other squeezed one of my big breasts.

I came again, screaming his name.

Reagan didn’t stop. He f****d me through it, then pulled out and flipped me onto my back again. He pushed my knees to my chest, folding me in half, and drove back in even deeper.

We f****d for hours.

He took me in every position...missionary, doggy, me riding him while my breasts bounced heavily in his face. He sucked and bit my n*****s until they were red and sensitive. He made me c*m over and over until I was sobbing and begging.

Each time his knot started to swell, he held back, teasing me with the promise of being locked together.

Only when the sky outside began to lighten did he finally let go.

Reagan pinned me down, thrusting hard and deep. His knot swelled fully, stretching me wide and locking us together. The pressure against my g-spot made me c*m instantly, screaming.

“Take my knot, little sister,” he growled against my neck, teeth grazing my skin. “Gonna fill this forbidden p***y until it takes.”

Hot spurts of c*m flooded me as his knot pulsed. He kept rutting shallowly, pumping more and more seed deep inside while we were locked together.

We stayed tied like that, breathing hard, his massive body covering my skinny one. His knot kept us connected, pulsing inside me.

Then we heard it.

Heavy footsteps coming down the hallway.

Reagan’s head snapped up. His father’s voice echoed faintly from the corridor...Alpha Harlan was walking toward this wing of the house, talking to someone in a low tone.

“s**t,” Reagan hissed, eyes wide with sudden panic.

His knot was still fully swollen, locking us together. He couldn’t pull out.

The footsteps grew closer.

Reagan’s face hardened with urgency. “We have to move. Now.”

He tried to shift, but the knot held us tight. Pain and pleasure mixed as he moved carefully, still buried deep inside me. I whimpered at the overwhelming fullness.

“Quiet,” he growled softly, but his voice was strained.

With a low curse, he finally felt the knot start to go down just enough. He pulled out quickly, a rush of c*m and slick spilling down my thighs. I gasped at the sudden emptiness.

Reagan yanked his sweatpants up fast and grabbed my clothes, shoving them into my arms.

“Get dressed. Hurry.”

I was still trembling, legs weak from hours of being f****d. Reagan grabbed my arm and pulled me toward the door, his grip firm and urgent.

The footsteps were right outside now.

He cracked the door open, checked the hallway, then dragged me out behind him. We moved quickly and quietly down the corridor toward my room, my heart pounding as we heard Alpha Harlan’s voice growing louder behind us.

Reagan pushed me inside my room just as the footsteps turned the corner.

He didn’t say another word.

He simply gave me one last dark, conflicted look before closing the door between us.

I stood there, naked, covered in his c*m, legs shaking, with my stepbrother’s seed still leaking down my thighs.

And the reality of what we had just done crashed over me like ice water.
