I was just hanging out in my bedroom, lying on my bed. I had on a comfy t-shirt and some black undies. My little ashtray was sitting right next to me. Mom and Dad were gone for the night, which meant the house was quiet, except for downstairs. My brother Mark and his friends were down there being loud. It was Friday, so they were probably playing poker, like they always do. Mark’s a year older than me, 19, and honestly, he’s just annoying most of the time.
Suddenly, I got really thirsty. Like, needed-a-drink right now thirsty. So I got off the bed and headed out of my room, down the stairs towards the kitchen. Oh man, I knew that’s where everyone would be. And I wasn’t really dressed up, my t-shirt barely came down far enough to cover my backside.
I walked into the kitchen, and yup, there they were. Mark and a few of his friends sitting around the table. The talking stopped for a second when I came in. Their eyes all seemed to land on me. Especialy Mark. He just stared at my legs as I walked past them to the fridge.
I opened the fridge door and leaned over to look for something in the back. That’s when I heard it. One of his friends mumbled something quiet, like a whisper just to Mark. “Dude,” he said, “she has such a nice butt.”
I heard Mark whisper back right away. “I know. Trust me, I totally know.”
I was still bent over, looking into the fridge, but I couldn’t help but smile to myself. And yeah, I definitely wiggled my butt a little bit on purpose while I was right there.
I grabbed a bottle of water from the back of the fridge, twisting the cap off as I straightened up. I took a long swig, trying to act casual, like I hadn’t heard their little exchange. But the heat was rising in my cheeks, and I could feel their eyes on me.
“Wait is that my shirt, ” he said as I took another drink.
“I am just borrowing it, I could take it off but I dont have a bra on,” I said as the lads looked at me. I saw marks hand under the table adjusting his crotch.
“You…you don’t have to do that,” he stammered, his eyes darting around the room, avoiding direct contact. “Just… just give it back when you’re done. Unless you want to give us all a show.”
“Yeah come on don’t blue ball us like that,” one of his friends said. “What a cock tease.”
I slowly lifted my shirt until it should abit of underboob and then put it back down, then when back to my room. “Have a good night boys.”
I made my way back up stairs and got on my bed, I grabbed the remote flicking through the tv channels. I became horny for some reason and found my hand between my legs rubbing my cunt through my panties.
I could feel my panties getting damp as I rubbed my pussy through the fabric. God, what was wrong with me? Teasing my brother like that… it was so wrong. But it had felt so good to see him squirm, to know that he wanted me.
I slid my hand into my panties, my fingers gliding through my slick folds. I was so wet already. I circled my clit with my fingertip, biting my lip to keep from moaning too loud. I imagined it was Mark’s hand down there, touching me. What would it feel like to have my older brother’s fingers inside me?
I plunged two fingers knuckle deep into my tight hole, pumping them in and out. The wet sounds of my fingering filled the room. My other hand came up to grope my small tits, pinching and tugging on my nipples through my shirt. I humped my fingers faster, fucking myself hard as I pictured Mark doing the same.
In my mind, he was on top of me, his strong body pinning me down. He ripped my shirt off and latched onto one of my nipples, sucking hard as he pumped his cock into my sopping cunt. I could almost feel him stretching me open, his thick rod splitting me in two.
“Oh fuck, Mark,” I whimpered, my back arching off the bed. I was so close, my pussy clenching around my plunging fingers. “I’m gonna cum on your big cock. Breed your little sis…”
Then my phone buzzed, it was from Mark. The text buzzed on my phone screen: “I can’t believe you nearly showed your tits lol. I saw abit of your underboob, sorry I shouldnt be texting.”
I stared at the text on my screen, my fingers still stuffed deep in my pussy. He was texting me right now? While I was imagining him fucking me senseless? God, this was so wrong. I shouldn’t be thinking about my brother this way. But I couldn’t help it.
I pulled my hand out of my panties with a wet squelch. My fingers were coated in my juices. I brought them to my mouth, licking them clean. I tasted myself, salty and musky. Fuck, I was really turned on.
I typed a response with my slick hand: “You’re the one who’s a perv, watching me like that. I saw you staring at my ass.”
His reply came right away: “I’m not a perv! You were the one prancing around in just a shirt. What did you expect?”
“I didn’t expect you to get a hard on from it,” I sent back, sliding my hand back into my panties. “I saw you adjusting yourself.”
There was a longer pause this time before his text came through. “So what if I did? You’re a hot piece of ass. Not my fault you have that effect on me.”
I couldn’t believe what I was reading. Was he really admitting he wanted me? I plunged my fingers back into my dripping cunt, fucking myself as I read his words over and over.
“Whatever. You’re just mad cause you got hard and your friends saw,” I typed, trying to sound casual even as I pumped three fingers in my tight hole. “Jealous? Wish you could bend me over right in front of them and show them who my ass really belongs to? Oh and I am upstairs fingering my pussy.”
His reply came through almost instantly, and my heart raced as I read the words on the screen:
“Fuck yes, I wish I could bend you over the table right now in front of everyone. Flip that little skirt up and spank your ass red until you’re begging for my cock. I’d make you scream so loud they’d all hear what a dirty slut you are for your big brother. Want me to send the lads home, and come to your room. Fuck it I am sending them home, be 5 minutes get that fanny out for me and wet.”
I stared at my phone in disbelief as I read Mark’s texts. Was this really happening? My own brother, coming to my room in a few minutes to bend me over and fuck me silly? It was so wrong, but god, it felt so right. I was dripping wet just imagining him pounding into me, claiming me in front of his friends.
But wait, he’d said he was sending them home and coming up here. Fuck, that meant he’d be alone with me, no audience. I felt a shiver of anticipation mixed with nerves run down my spine. My breath quickened as I pictured him standing over me, tall and strong and dominant, pinning me down as he ravaged me. Shit, I was getting worked up again already.
My heart raced as I heard the rumble of voices downstairs, Mark giving his friends some excuse to leave. Footsteps creaked on the stairs, getting closer. I scurried to the door and locked it just as a knock sounded. I took a deep breath, trying to calm my nerves.
“He…hey Mark, come in,” I called, my voice quivering slightly. The lock clicked and the door swung open. There he stood, filling up the doorway, his tall frame towering over me. His eyes raked over my body hungrily, drinking me in. I stood there in just his shirt, my pert nipples straining against the thin fabric, my pussy clenching with need.
“Lock the door behind you,” I commanded, trying to sound bold and in charge, even as my hands trembled at my sides.
He smirked, shutting the door and twisting the lock. “Don’t want anyone to hear you scream, baby sis?” he purred. My whole body flushed at his low, seductive tone.
“M-Maybe,” I stammered, feeling so tiny and vulnerable under his intense gaze. God, he was so big, so strong. I felt my panties get even wetter.
“Come here,” he growled, crooking a finger at me. “I wanna taste that sweet little pussy.”
I scurried over to him, my heart pounding. He grabbed me, pulling me flush against his hard body. I could feel his thick cock pressing against my stomach through his jeans. Oh fuck, he was huge. I whimpered as he groped my ass, squeezing the plump flesh.
“Mmm yeah, this belongs to me now,” he rasped, his fingers digging into my cheeks. “I’m gonna ruin this tight cunt for anyone else.”
Yes, god yes, ruin me, I thought hazily. But all that came out was a needy moan as he lifted me up. My legs wrapped around his waist on instinct and he carried me to the bed, tossing me down. I bounced on the mattress, my shirt riding up to expose my hairless mound.
“Fuck baby girl, I knew you’d be bare,” he groaned, dropping to his knees between my legs. “Gonna eat this pretty pussy ’til you’re begging me to stop.”
He spread my legs wide and I cried out as he buried his face in my cunt. His tongue lashed over my clit and I nearly screamed, fisting my hands in his hair. He licked and sucked at me, his nose bumping my clit as he tongue-fucked my hole. I was so slick he could plunge his tongue deep, drinking down my juices.
“Oh god, Mark, yes!” I wailed, humping his hungry mouth. He growled into my pussy, the vibrations making me see stars. He fingered my hole as he ate me out, scissoring and curling them just right.
“Ah ah ahhh, ‘m close!” I panted, my thighs quaking. I was gonna cum so hard on my brother’s face. What a dirty slut. I bucked against his stroking fingers, my pussy clamping down.
“That’s it, cum for me baby,” he urged, sucking hard on my clit. “Fucking soak my face.”
I let out a high keen as my orgasm crashed through me. My pussy spasmed and gushed, squirting all over his hand and chin. He lapped it up greedily, still tonguing my clenching hole. I thrashed on the bed, overwhelmed by the intensity of it.
Finally I collapsed back, chest heaving. He gentled his touches, kissing my sensitive clit. Then he stood and stripped off his shirt. My eyes went wide at the sight of his muscled chest and abs. Fuck, he was gorgeous.
But my eyes were drawn lower, to the huge bulge straining the front of his jeans. I licked my lips as he unzipped them, reaching in to pull out his cock. It slapped against his stomach, long and thick and angry red. The flared head leaked pre-cum. I’d never seen a cock so big before.
“Is it…is it gonna fit?” I asked breathlessly, feeling nervous and awed by the size of him.
“Oh it’ll fit, don’t worry,” he rumbled, pumping his shaft. “Gonna stretch this tight little cunt so good. You’ll be feeling me for days.”
I shivered at his words, my pussy clenching and dripping on the sheets. He inched closer, his cock nudging between my slick folds. I whimpered as he notched the fat head at my entrance.
“Holy shit, you’re so fucking small,” he groaned, pushing forward. The flared tip popped inside me and I let out a high keen at the sudden stretch. “Fuuuck, knew you’d be tight but goddamn.”
He hilted himself in one hard thrust, burying his thick cock balls deep in my pussy. I wailed, my back arching off the bed. He was so big he felt like he was in my stomach. My cunt stretched obscenely around him, molding to his shape.
“Oh god oh fuck, Mark!” I babbled, my eyes rolling back. “You’re so deep, I c-can’t…ahhh you’re splitting me open!”
“Take it, fucking take it,” he snarled, starting to move. His hips snapped against mine, driving his cock in and out of my gripping hole. The wet sound of skin slapping skin filled the room along with my desperate moans.
“It’s so big, I’m gonna break,” I sobbed, my thighs quaking around his pistoning waist. But fuck if it didn’t feel amazing stretching me open like this. His thick shaft rubbed against my g-spot with every thrust, sending sparks of pleasure zinging through my nerves.
“You can take it, such a good little cock sleeve,” he grunted, hammering into me. “Gonna fucking ruin you for anyone else.”
I could only wail and babble incoherently as he pounded me into the mattress. My tits bounced with every rough thrust, the thin shirt doing nothing to conceal my jiggling mounds. Mark reached up to rip it off me, exposing my pert breasts to the cool air.
“Fuck, look at these little tits,” he groaned, palming the small globes. He pinched and rolled my nipples between his fingers until I was keening, humping my hips to meet his thrusts.
“I’m so close, gonna…gonna cum on your cock!” I warned, my pussy starting to flutter. He just growled and slammed into me harder, his heavy balls slapping my ass.
“Do it, fucking cum on your big brother’s dick,” he commanded, twisting my nipples just shy of too hard. “Squeeze the cum out of me.”
I came with a scream, my pussy bearing down on him like a vice. My whole body shook with the force of it and I squirted clear fluid all over his cock and balls. He roared and slammed deep, his shaft pulsing as he flooded my clenching cunt with his hot seed.
I could feel him pumping spurt after spurt into my spasming hole, painting my insides white. It was so much cum, my pussy overflowing with it. Some dribbled out around his shaft to soak the sheets beneath my ass.
Holy fuck, I’d just let my brother fill me up with his cum. What the hell was I thinking? This was so wrong…but it felt so right. I’d never cum so hard in my life. As we collapsed together in a sweaty tangle of limbs, I knew I’d never be able to look at him the same way again.
Mark shifted and I whimpered as his softening cock slid out of my tender, used pussy. A river of cum followed, gushing out of my gaping hole to puddle on the sheets. I felt empty without him inside me.
“Shit, I gotta go before mom and dad get home,” he muttered, pulling his jeans back on. I just nodded mutely, watching him through hazy eyes. My whole body ached so good.
He leaned down to press a surprisingly gentle kiss to my sweaty forehead. “Thanks sis,” he murmured. “That was…wow. We’ll have to do that again sometime.”
Then he was gone, slipping out of my room and down the stairs. I laid there in the mess of cum and sweat, my mind reeling. What had I just done? What the fuck were we going to do now?
One thing was for sure – I’d never be able to think of my brother the same way again. And god help me, I couldn’t wait to be stretched out on his cock again. I was utterly fucked – in more ways than one.
