A Brother Always Knows

Everyone is 18.

Chapter 1: Night of Terror

"Thought you could just steal my shit and get away with it, huh?" Bret growled, his voice low and dripping with menace. Mom and Dad were gone for the weekend, so I knew I was fucked.

His hand was already at the back of my head, his fingers tangling in my hair, forcing me down onto my knees. My heart pounded so hard it felt like it might burst out of my chest. I hadn’t expected this—not now, not like this. The room felt like it was shrinking in on me, the air was thick–it was hard to breathe as his shadow loomed over me. I couldn’t think. All I could do was submit.

It had started after the humiliation of the night before. I’d been replaying every single moment in my head—the way his cock had looked as I watched him fucking the girl from school I told him I had a crush on, the way he’d taken control of her so effortlessly, the way I’d wanted him to do so. I’d been unable to sleep, my skin still tingling with the memory of his hands on her, his load dripping out of her afterward as she casually wiped it away and got dressed, the way he spit on her asshole, and stuck a thumb inside as he finished in her pussy, with his big cock throbbing and his big, round, masculine ass cheeks sticking out like globes, a long exhale from his mouth telling me he was finally done with his orgasm. I’d woken up hard, my cock sticking out of my pajama pants waistband, the sheets twisted around my legs, my mind already racing back to the stolen moments in his doorway watching him, the way he’d discovered me spying and spanked my naked ass right in front of her, the discovery that I loved that too. The look on her face as she chuckled, a mix of pity and appreciation for the strange brotherly dynamic.

Determined to chase that feeling again, I’d gone back to the only thing I had left—the pictures and videos I’d taken from his phone when he was in the shower that morning. I had seen him type in his passcode before, and it was locked away in my brain for future use. When I had the chance, I simply had to see if he had gotten nudes from her, and if he had sent anything back. This pervert had saved everything she sent on snap, and he had sent plenty of shit back to her. And, they weren’t just images; they were him. His body, his moans, his satisfaction at having a girl to play with on Snap. I’d put on my headphones to drown out the world, to make it just me and him and the beautiful girl from school in my room. The video on my laptop screen was the closest I could get to them, and I’d been transfixed, my hand already working myself into a naked frenzy when I’d felt the headphones ripped off my head.

And now here I was, on my knees, his cock already out, already hard, already inches from my face. I didn’t need words to know what he wanted. He’d made it clear the night before—he wasn’t asking, he was taking. And I wasn’t resisting.

The first thrust was brutal, his thick cock slamming into the back of my throat before I could even think to prepare. I gagged, my hands instinctively reaching up to try to push him away, but he only grabbed my wrists, pinning them behind my back. My throat burned, my eyes watered, but I didn’t stop. I couldn’t. There was something about this—about him—that made me crave the pain, the dominance, the way he used me like I was nothing more than a toy for his pleasure.

He pushed deeper, his hips snapping forward with a force that made my head spin. I tried to breathe through my nose, but it was impossible—he was too deep, too much. My body shuddered, my cock throbbing uncomfortably in my pants, and I realized with a mix of shame and excitement that I was hard from this.

"You like this, don’t you?" he snarled, his voice thick with something like disgust. "You’re fucking pathetic."

I wanted to deny it, to pretend this wasn’t exactly what I’d been craving, but I couldn’t. My body betrayed me, my hips bucking slightly as I tried to relieve some of the pressure building in my groin. He noticed, of course. He always noticed everything I did. I tried to imagine the taste of her pussy still on his cock from the night before.

"You’re really disgusting," he said, but his grip on my hair tightened, and he pushed even harder, his cock stretching my throat to its limit, making me body retch and my eyes water. "You’re nothing but a filthy little fag, aren’t you?"

The word stung, gave me a feeling of even deeper humiliation in the pit of my stomach, but it only made me harder. My mind was a mess of conflicting emotions—shame, arousal, submission. I didn’t want to stop, even though every fiber of my being was screaming at me to pull away, to fight back. But I couldn’t. I wouldn’t.

He pulled out suddenly, leaving me gasping for air, my mouth hanging open, drool dripping down my chin. Before I could recover, he yanked me to my feet, spinning me around and shoving me face-first into the bed. His hands were rough as he pulled apart my ass cheeks. Oh god, not there, I thought. His fingers digging into the flesh of my teen ass and playing with it like a piece of meat.

"Are you gonna…" I whimpered, unable to finish as a knot rose in my throat. 

He laughed, a harsh, mocking sound that sent a shiver down my spine. 

“Maybe I will,” he said darkly, his strong hand on the middle of my back holding my body down on the bed. He began to tap the head of his thick, wet cock against my hole, and I was immediately transported to another dimension. A strong man was going to use me, and this is where I was always meant to be. This was my place in the universe. There was a reason I was hard this entire time–Bret deserved to fuck me, and this was my role. He gets to fuck beautiful girls effortlessly, and I get to submit to him.

“Do it,” I said quietly, my voice barely above a whisper, “use me.”

"You’re begging for it now? Pathetic."

I wanted to deny it, to tell him he was wrong, but I couldn’t. I was pathetic. And I liked it.

He didn’t waste any time, his fingers probing my entrance as he spit on my hole, stretching me open with two thumbs without any care for how much it would hurt. I bit down on the pillow, trying to stifle the sound that escaped my lips, but he wasn’t having it.

"Louder," he demanded, slapping my ass hard enough to leave a mark. "I want to hear you."

–[]–

I obeyed, my voice trembling as he pushed inside, his cock stretching me in ways I didn’t even know were possible. It hurt—like fuck—but there was something else burning in me too, something electric, something alive.

He didn’t hold back, his hips slamming into me with a force that drove the air from my lungs. It felt like his large, manly cock was pushing directly against my stomach. My hands clawed at the sheets, my body trembling as he pounded into me, his breath hot against my ear.

"You’re just a hole now," he growled, his voice sounding dangerous. "You hear me? You’re a backup piece of ass for me from now on." He was getting off on owning me. "You're my pre-warmed fleshlight."

I nodded, unable to speak, unable to think. All I could do was feel—the pain, the pleasure, the overwhelming sense of submission. My cock was leaking, pre-cum staining the sheets beneath me, but I didn’t care. All I cared about was him.

He didn’t stop, didn’t slow down, didn’t give me even a moment to catch my breath. He didn't even slow his rapid thrusts as we added more spit to his cock. It was relentless, brutal, perfect. I could feel him getting close, his pace faltering slightly as he neared the edge. I was pushed against my bed like a ragdoll, and my cock was generating rapid friction with my soft comforter beneath me. My whimpers turned into pleasured moans, and they became increasingly high-pitched, even feminine. I didn't know a guy's throat could even emanate those kinds of sounds after puberty.

"Don’t cum," he demanded, his voice harsh, commanding.

I didn’t want to go against his demands, but my body disobeyed, my release crashing over me like a wave, my cock pulsing as I spilled onto the sheets and rubbed it in with my stomach. He slapped me as an ad hoc punishment, harder than before, right on my ass cheek, and he followed in his own climax shortly after, his hips jerking forward as he buried himself deep inside me, his release hot, and heavy.

He pulled out without a word, leaving me trembling, my body still reeling from the intensity of it all. I didn’t know what to say, how to feel. All I knew was that I wanted more.

I lay back on the bed, my body quivering with the rapid shift in my life dynamic.

Suddenly, the look on his face became bright, satisfied, casual. The mood changed. I was disappointed that my domination sesh was ending, but also relieved to see my brother be himself again.

After a minute of silence, he finally spoke. “What did you think?” I paused for a minute before answering, my mind trying to process it.

“I don’t know what the fuck that was,” I admitted.

“I just thought you’d like it,” he said, shrugging.

“I can’t believe you fucked Erica,” I said with a sigh.

“I’ve been watching you dude. You wanted me to fuck her. And you wanted to watch. I know a cuck when I see one.” 

My jaw dropped. “How did you know I would like that? I didn’t even know.”

“A brother always knows,” he said. I waited a beat, absorbing what he was telling me.

“Did you know I stole all your pics? And those snap videos?”

“I kinda figured, and I don’t blame you.” My lips curled, an insane night of sex and the insanity of my brother making me question all of existence.

"Your laptop is mine now by the way. It wasn’t fair you got a nicer one anyway," he said, "Now get the fuck out of my room." His voice was assertive, a smile on his face.

“It’s… my room,” I muttered, chuckling. 

“Not anymore, it’s my workout room until Mom and Dad are back. Sleep on the couch.” His demand was assertive.

I obeyed, my legs shaky as I pulled my pants up and stumbled toward the door. But before I could leave, he grabbed my arm, spinning me around to face him.

"You probably shouldn’t tell anyone about this," he said, his eyes relating an implicit threat to me.

I nodded, swallowing hard. I believed what his eyes were telling me. This is fucking crazy, I thought to myself.

And as I walked back to my room, my body still trembling, my mind still spinning, I couldn’t help but wonder… what would he make me do next?
