Jake’s POV

Last night was hot. Like fuck. To tell me that my stepsister would taste better than anyone I've fucked would have been a lie until yesterday.

I lay flat on my back in my bedroom, staring up at the ceiling fan spinning lazily, but my mind had completely drifted to all happened between my stepsister and I last night.

I wanted to take my mind off her and convince myself that it was just a one time experience I may never get to have again, but just couldn’t.

My room was begining to scent like her, like she was in here with me all night. It smelt like a mixture of my thick cum and her sweet sticky squirt.

Before yesterday, I honestly thought she was just that naive, quiet girl who cared little or less about my existence. We barely talked. We had almost zero interactions with each other outside of a mumbled "good morning" or passing each other in the hallway while going about our separate ways. I figured she looked at me as the annoying older stepbrother who was just occupying space in the house after college. But fuck, I was completely wrong.

Yesterday changed everything. I discovered she had something inside her—a raw, untameable hunger—that was going to keep drawing me back to her like a fucking addict I was becoming. I couldn't stop thinking about her. I kept picturing the look on her face when I dipped my hands into her pussy for the very first time on that couch. She was so incredibly wet, her tight little entrance dripping before I even touched her clit. And she came multiple times, screaming, shaking, and soaking my fingers, all because of me.

Just thinking about the way her tight pussy stretched when I was going in and out of her, made my sweatpants feel completely suffocating.

I reached down, gripping myself through my shorts. My dick was already stubbornly hard, a thick, rigid pillar pressing uncomfortably against my stomach. I pulled the waistband down, letting my ten-inch cock spring free into the cool air of my bedroom. It was already fully erect, veiny, and throbbing with a violent pulse, the heavy head dark purple with precum leaking from it's tip.

I got back on the bed, wrapping my hands around my cock. I needed to ease this tension right away. I began to stroke myself slowly, my thumb sliding over the sensitive skin right beneath the head, smearing the pre-cum down the length of it.

"Emma," I growled out loud into the empty room. Her name rolled out too seductively on my tongue.

The moment my eyes closed, the memories came flooding my head again. I pictured her bent over the couch, those tiny sleep shorts bunched up around her waist, revealing the full, smooth cheeks of her ass. I remembered the exact sound of her voice when she broke down, crying and begging me to stretch her open with my huge cock. The stretch had been so tight, so goddamn perfect, that I felt like I was tearing her apart, in the best way possible. Her inner walls gripped my shaft, milking me from the very first deep thrust I made inside her.

I increased my pace, tightening my grip on my cock. It felt so good, but it wasn't enough. I wanted her mouth. I wanted to feel her wet, tight lips stretching wide to accommodate my thickness, just like she did when she was down on her knees on the living room floor, taking the fat head of my dick into her throat until tears pricked her eyes. She had been such a good, obedient little cocksucker, swallowing my pre-cum and cleaning me up like a pro.

"Fuck, Emma..." I groaned, my hips bucking off the mattress as my hand pumped faster.

My mind shifted to the shower session. I could almost feel the hot water cascading over my shoulders, mixing with the slick, sticky juices covering her pussy. I imagined myself dropping to my knees on those cold bathroom tiles, burying my face entirely between her thighs. She had tasted so fucking sweet, even with the heavy taste of my own cum mixed into her. I remembered how desperately her hips bucked against my mouth when my tongue dived deep inside her creampied entrance. She had squirted right down my chin and chest, her entire body convulsing as she yelled my name over and over.

The memory was so intense, so vivid, that my balls turned hard against my body. I slid my left hand to reach down, cupping my heavy sack, my fingers squeezing and rolling my testicles while my right hand furiously worked my cock. I took one of my fingers, slick with my own pre-cum, and pressed it right against my own opening, tracing the tip just like she had done to me in the shower right before we came in each other's faces.

The overload of the fantasy pushed me right over the edge.

"Yeah, take it, Emma... suck it clean, you little whore," I grunted out loud, my voice deep and ragged.

I got into a brutal pace, slapping my hands against my lower belly. My cock locked up, my toes curling as a massive wave of pleasure exploded through me. I groaned into the quiet bedroom, my hand still pumping violently as my cock erupted with cum. Load after load of thick, hot, white cum shot out of me, moving through the air and splattering heavily across my own chest and stomach.

I remained on my bed panting heavily, my chest heaving as the aftershocks rippled through my cock. But the satisfaction didn't last more than a few seconds. Usually, after a release like that, a guy cools down. The urge goes away. But not today. Not with Emma sleeping just a few doors away.

My dick didn't even go soft. It stayed stubbornly hard, throbbing heavily against my sticky abdomen. The image of her tits bouncing wildly against the wet shower flashed in my mind again. I thought about her long, slender fingers rubbing her own swollen pussy lips while I sucked her clit.

"Fucking hell," I muttered, my hand gripping my shaft again without even thinking.

I didn't even bother to wipe the fresh cum off my chest. I just started stroking myself through the mess, using my release as a lubricant to pleasure myself. It felt entirely different this time—sensitised, dirty, and incredibly dominant. I closed my eyes and pictured the next thirteen days we had left alone in this house. Thirteen days of having complete, unrestricted access to her body. I'd fuck her on the kitchen counter. I'd bend her over the dining table. I'd make her wake me up every single morning with her tight mouth wrapped around my cock.

The thoughts worked me right back into the mood. My cock went back to a more full, monstrous hardness, veiny and rigid, practically begging for another release. I pumped myself harder, my thumb working the sensitive head, forcing the arousal to build at a dangerous speed. I imagined myself burying my cock so deep in her pussy that she wouldn't be able to form a proper sentence, just broken, breathless whimpers of my name.

Within minutes, my balls tightened again, and I felt that heavy, aching pressure building up in my groin. I let out a low growl, my hand moving in an unpredictable furious motion up and down my ten-inch cock.

"Emma... fuck... you're mine," I hissed, my hips jerking violently as I came hard for the second time. Another heavy release of thick cum pumped out of me, joining the mess already drying on my stomach, leaving me completely spent and covered in my own release.

I stayed completely still for a few minutes, my breathing slowly returning to normal. The house was dead silent. I finally sat up, grabbing a clean towel from the side of the bed to roughly wipe the sticky white fluid off my chest and stomach. I pulled my sweatpants back up over my hips, but even after two explosive releases, the dull, heavy ache in my groin wouldn't entirely disappear. My cock was still thick, resting heavy against my thigh, refusing to go completely soft.

I realized I couldn't stay locked up in my bedroom any longer. The walls felt like they were closing in on me. I needed to see her. I needed to look at her face in the morning light to confirm that yesterday hadn't been some kind of wild, feverish dream.

I quietly opened my bedroom door and stepped out to the hallway. I took silent steps as I made my way downstairs toward the kitchen, expecting to find her making coffee.

On getting to the kitchen, I saw something that made me froze.

It was her.

Emma.

She didn't seem to notice my presence at all. She was completely turned away from me, her back bathed in the warm morning sunlight filtering through the glass.

She had on a pair of tiny, thin white cotton panties that sat low on her hips, the fabric stretched tight across the smooth, round curve of her ass, showing off the full pack of her silhouette. But it was her upper body that made my heart slam violently against my ribs.

She had no bra on. Nothing at all.

Her back was completely bare, her slender shoulders and the delicate curve of her waist entirely exposed to the open room. From the angle I was standing, I could see the soft, round swell of the side of her bare breast, the heavy weight of it hanging beautifully as she lifted a hand to brush a stray strand of hair behind her ear.

I stood completely transfixed in the doorway, my muscles locking up as my eyes dragged slowly down the length of her exposed skin.

My sweatpants instantly grew tight again as my cock slammed back to full, throbbing hardness, threatening to rip right through the fabric at the mere sight of her.

I couldn't move. I just stood there, watching her, my hand unconsciously reaching down to grip my cock through my sweatpants as the memories of last night flooded back even stronger.

Emma's POV

The cold morning air touched my bare skin, sending a light shiver through me, as I stood by the living room window. I was still half-asleep, my body aching in places I couldn't name. Last night was gone in a blur, but the memories of the hot bath, our slick skin, and the terrifyingly huge stretch of Jake’s ten-inch cock still stuck to my head. I could still feel the sensations I felt when his huge cock entered my pussy.

I had gone downstairs minutes ago, wearing nothing but a pair of tiny, lace panties. My sleep shorts were still upstairs, probably damp and discarded on the bathroom floor alongside our wet towels. I didn't bother to put on a bra or even a shirt. I just needed to get down to the kitchen, grab a glass of water, and maybe start cleaning up the disaster we had made of the living room before I let the reality of what we had done fully set in.

I turned away from the window, intending to head toward the kitchen, but the moment I stepped into the doorway, I froze.

Jake was standing there.

He was leaning against the wall, his tall, muscular frame completely blocking the exit. He had nothing on, but a pair of loose gray sweatpants that hung too dangerously low on his hips, and at that point, my eyes betrayed me. Multiple times even when I tried to control it. It immediately darted down to the massive bulge of his cock peeking through his shorts. It was already hard, thick and heavy.

My pussy heated up instantly when I saw his cock grow longer. He was turned on already all because of me, and I knew it.

My heart banged heavily, as I squeezed my hands and toes, trying to restrict myself from coming. He must not see me this way. Getting turned on right in the front of him.

Instinct took over before my brain could react. My hands flew up to my chest, my arms crossing tightly over my bare breasts, hiding my hard, highly sensitive nipples from his dark, intense gaze. My breath hitched in my throat, a sudden wave of panic washing over me.

Oh my god, he’s looking right at me. I’m completely naked, I thought.

But then, as I stood there panting, the memories of last night retuned.

I remembered the way his rough, firm hands had gripped my ass. I remembered the sensations I felt when he had his fingers deep inside my wet, creampied pussy, stretching me open while his mouth latched on my clit in the shower. I remembered how I had literally bent over the couch, begging him to split me open, and how I had eagerly sucked his thick cum right off his shaft, tasting our combined release without a single feeling of shame.

Then, it clicked.

Why the hell was I covering myself? I thought, a sudden, rush of heat surging through my pussy. He already saw every single part of me. He’s claimed every single part of my body.

Slowly, deliberately, I let my arms fall back down to my sides. I stood tall, exposing my full, round breasts to him. My nipples instantly puckered, hardening under his hot gaze. I felt incredibly vulnerable, my skin burning under his gaze, but there was a sick, addictive thrill in letting him look at me like this.

The silence between us sickening. Neither of us moved. I shifted my position awkwardly from one foot to the other, my wet slit rubbing against the thin lace of my panties, reminding me that I was still leaking a tiny bit of his dried cum from the night before.

I swallowed hard, my throat feeling incredibly dry. I needed to speak. I needed to say something to break the tension before we ended up ripping each other's clothes off again, because God knows my body was practically screaming for it.

“Jake…” I called out, like he wasn't he front of me.

He didn’t answer. He just kept his eyes locked on mine, his nostrils flaring slightly as he took a deep, slow breath.

“I…” I took a step back, my thighs pressing tightly together to try and stop the sudden, throbbing ache between my legs. “I’m sorry about yesterday. All of it. It was my fault.”

A tiny flicker of emotion crossed his handsome face, his eyebrows drawing together slightly. But he still didn't say a word, forcing me to keep going. This was the only way I knew I could end every sexual interactions with him.

But come to think of it, what if Dad and Mom's finds out? In swear they're going to kill me. They'll know I seduced him first, and if you're asking why, it's simply because they've seen me.

They've seen me moving around on the short skimpy underwear that whenever they asked about it, I'll tell them it's just an underwear, nothing else, and besides, we're at home.

And maybe they trusted me enough that they stopped asking. I was something, not everything, while living with my parents.

“I’m sorry for seducing you,” I whispered, looking down at the floor, unable to hold his intense gaze any longer.

“I know I was the one wearing those tight shorts, and… and doing things to get your attention. I shouldn't have crossed that line. We’re stepsister and stepbrother, Jake. Mom and Dad already warned me about this, and If they ever found out… oh my god, it would literally kill them.”

I looked back up at him, my eyes wide with a sudden panic. “Please, Jake. You can’t tell them. You can't let them know what we did. We have to keep this a secret. It was just… a mistake. A really, really crazy mistake because we were left alone, and I didn't know what came over me. Please promise me you won't say anything.”

Jake’s expression darkened instantly. The relaxed, lazy posture he had been holding disappeared, replaced by a stiff intensity. He took a slow step toward me, his bare feet making no sound on the floor.

Emma's POV

“A mistake?” he repeated, as if the word itself offended him. His voice didn’t just vibrate in my ears, it hit me straight in my pussy, like it was questioning the decision personally.

My breath caught as he closed the distance between us. He was so much taller than me, his massive frame completely swallowing me up as he stopped just inches away. The scent of his skin mixed with the faint smell of our sexual release hit my nose, making my knees go weak.

He reached out, his large, calloused hand gently cupping my jaw. His thumb wiped away a stray tear I hadn’t even realized had escaped. He leaned down, his eyes scanning my face with a terrifying amount of hunger, before his lips moved toward mine, aiming for a deep, possessive kiss.

But just before our lips could touch, my instincts screamed at me. I jerked my head away, and his lips brushed against my cheek instead.

Jake froze. His hand on my jaw tightened slightly, not enough to hurt, but enough to hold my head in place. I could feel the sudden shift in his energy, his breathing turning hot against my neck.

“What’s wrong with that, Emma?” he growled, his voice filled with frustration. “Last night you couldn’t get enough of my mouth. You were begging me to eat your pussy and suck on your tongue. Now you’re pulling away?”

“We can’t do this, Jake,” I whimpered, pressing my hands against his bare chest, trying to create some distance. But it was like pushing a brick wall. His chest was hard, and the feel of his warm skin beneath my palms only made my heart beat faster. “It’s wrong. We’re supposed to be family. Yesterday… let’s just say it was an accident. But right now, we need to stop before we make things worse.”

Jake let out a dark, mocking chuckle. He released my jaw only to grab both of my wrists, pinning them gently but firmly against his chest, right over his beating heart.

“You think we should call it an accident?” he hissed, leaning in so close his nose brushed against mine. “You think me burying my cock ten inches deep inside your tight little cunt was an accident, Emma? You think the way you screamed my name while you squirted all over my face in the shower should be called an accident?”

I tried to look away, but he wouldn’t let me.

“Look at me,” he commanded.

I did, my eyes wide and trembling.

“I’m not letting you call yesterday a mistake,” Jake said, his voice suddenly turning soft and far too sincere. “I’ve been watching you for months, Emma. Ever since I moved back. I was going crazy trying to stay away from you. But last night… last night proved to me that you feel the exact same way.”

He took a deep breath, his eyes melting with an emotion I had never seen in him before. “I’m in love with you, Emma.”

My jaw dropped, my heart stopping completely. “Jake… what?”

“I’m in love with you,” he repeated. His grip on my wrists loosened as his hands slid up to cup my face, his thumbs stroking my cheeks. “I don’t care what Mom and Dad think. I don’t care about what’s ‘right’ or ‘wrong’ according to everyone else. I want to be yours. I want you to be my girlfriend. I want us to be together for real.”

“We can’t,” I sobbed as the tears finally spilled over. “We’re stepsiblings, Jake! Everyone will look at us like we’re monsters. Our parents will disown us.”

“Let them,” he growled, his eyes turning fiercely possessive. “I don’t give a fuck about any of them. All I care about is this pussy right here.” He dipped his hand into my panties and touched me, making me arch my ass forward. “And the girl attached to it. You’re mine, Emma. You’ve been mine since the moment you let me stretch you out on that couch.”

He didn’t give me a chance to argue. Before I could utter another word, his mouth crashed into mine.

It wasn’t a gentle kiss like the ones you read about in books or see in movies. It was a punishing, demanding claim. He parted my lips easily, his thick tongue diving deep into my mouth and swirling around mine with dominant, possessive hunger. I let out a muffled moan against his lips, my hands instantly gripping his shoulders. The overwhelming power of his kiss completely melted my resolve. My body betrayed me instantly. My pussy clenched hard, releasing a hot, gushing wave of wetness that soaked through my panties.

Jake groaned into the kiss, feeling my surrender. He broke it for just a second, his eyes wild and dark with lust as he looked down at me.

“You’re so fucking wet for me, little sis,” he growled. His hand slid down my stomach, over my bare hip, before his thick fingers slipped beneath the waistband of my lace panties.

I gasped as his warm, calloused fingers made contact with my swollen, dripping pussy lips. He didn’t hesitate. He pushed two fingers straight into my tight entrance, stretching my sore walls from the night before.

“Oh my god, Jake… mmmph!” I cried, my head falling back against the wall as he began pumping his fingers inside me, hitting my G-spot.

“Tell me you’re mine,” he commanded, his thumb ruthlessly rubbing my engorged clit. “Tell me you want your boyfriend’s cock inside you right now.”

“I’m yours… yes, Jake, please!” I cried, my hips helplessly bucking against his hand. “I want it. I want your huge cock so bad!”

A vicious growl escaped his lips as he gripped the sides of my thin lace panties and ripped them apart. The fabric tore with a sharp snap before he tossed the ruined scraps to the floor.

He didn’t even bother carrying me to the couch. He grabbed my hips, lifted me effortlessly, and pressed my back hard against the living room wall. My legs instinctively wrapped around his waist, my bare pussy completely exposed and dripping down his stomach.

With his other hand, he yanked his sweatpants down. His monstrous ten-inch cock sprang free, fully hard, veiny, and throbbing violently. The fat head leaked a heavy amount of precum as he guided the tip directly against my soaking wet, swollen slit.

“Wrap your arms around my neck, Emma,” he growled, his muscles bulging as he held my entire weight against the wall. “Because I’m about to fuck you so hard you won’t remember your own name.”

I locked my arms around his neck, burying my face in his shoulder, my heart pounding so hard I could hear it in my ears.

“Please, Jake… do it,” I begged, my voice breaking. “Fuck me.”

He positioned his cock just a few inches from my entrance, his eyes already dark and needy.

“Ready?”

That was the last thing I heard him say before I felt his cock slam all the way to the back of my womb.
