My name is Ethan, I’m 28 years old, and I live in Los Angeles. My younger sister, Mia, is 25, and she’s a total knockout—34D-sized breasts, a slim waist, and an ass that looks incredible in her tight leggings. We’ve always been close, but lately, I’d caught her staring at me with a hunger in her eyes I couldn’t ignore. One night, she made it clear she wanted my big cock, especially in doggy style, and what happened next was the hottest, wildest night of my life.
It was a warm Saturday night. Our parents were out of town, leaving just me and Mia at home. I was in my room, shirtless in a pair of shorts, when she knocked on my door. She walked in wearing a skimpy tank top and tiny shorts, her breasts practically spilling out and her ass swaying as she moved. “Ethan, can we talk?” she asked, her voice low and teasing. I nodded, and she sat on my bed, her eyes locked on my crotch. “I’ve been thinking about you… a lot,” she confessed, biting her lip. My heart pounded—this was my sister, but the lust in her gaze was undeniable.
“Mia, you’re gorgeous,” I said, my voice husky. She smiled and leaned in, kissing me hard. “Ethan, I want your big cock,” she whispered against my lips. I didn’t hesitate—I pulled her tank top off, revealing her breasts—round, firm, and begging to be touched. I grabbed one and started sucking. “Oh fuck, Ethan, suck my tits!” she moaned, her hands in my hair. My tongue flicked over her nipple, and I sucked hard, making her squirm. Her pussy was already wet—I could smell her arousal through her shorts.
I yanked her shorts down, exposing her pussy—tight, glistening, and ready for me. “Ethan, I’ve fantasized about this,” she said, spreading her legs. I dropped to my knees and started licking her pussy. “Oh God, Ethan, lick my pussy!” she screamed, her ass lifting off the bed as my tongue teased her clit. I sucked and licked, tasting her sweetness, and she trembled with every stroke. “Suck it harder, make me cum!” she begged, her pussy dripping as I devoured her. She was so turned on, I knew she needed my cock next.
“Mia, I want you to suck me first,” I said, standing up and dropping my shorts. My cock sprang out—9 inches long, thick, and rock-hard. “Holy shit, Ethan, it’s so big,” she gasped, wrapping her lips around it. She started sucking, her tongue swirling around the tip before taking me deeper. “Fuck, Mia, suck my big cock!” I groaned, grabbing her head. She sucked with enthusiasm, her lips tight around me, saliva dripping as she worked my shaft. I thrust into her mouth, fucking it gently. “You’re so good at this, sis,” I growled, my cock throbbing in her warm, wet mouth.
After a few minutes of her sucking, she pulled back and got on her knees on the bed. “Ethan, I want your big cock in doggy style,” she said, sticking her ass up in the air. Her pussy was glistening, begging for me. I positioned myself behind her, rubbing my cock against her slit. “Fuck me, Ethan, fuck me hard!” she pleaded. I thrust forward, my big cock sliding deep into her tight pussy. “Oh fuck, Ethan, it’s so big!” she screamed, her breasts swaying as I started pounding her. My thrusts were fast and deep, each one driving my cock into her core. “Fuck me, Ethan, fuck my pussy!” she moaned, pushing her ass back against me. I grabbed her hips and fucked her harder, the sound of our bodies slapping together filling the room.
“God, Mia, your pussy is so tight,” I grunted, loving how she gripped me. After a while, I pulled out and spread her ass cheeks. “Ethan, what are you—” she started, but I cut her off. “I’m going to fuck your ass too,” I said, spitting on her asshole and pressing my cock against it. “Oh no, Ethan, it’s too big!” she protested, but I eased in slowly. “Oh fuck, Ethan, my ass!” she cried, her ass stretching around my big cock. It was insanely tight, but I fucked her steadily, then harder. “Your ass is fucking perfect,” I groaned, reaching around to squeeze her breasts as I pounded her from behind. “Fuck me, Ethan, fuck my ass hard!” she moaned, her pussy dripping as I took her in doggy style.
I flipped her onto her back after a while. “Mia, I’m going to cum in your pussy,” I said, sliding my cock back into her wet slit. I fucked her fast, her legs spread wide, her breasts bouncing with every thrust. “Fuck me, Ethan, fill me with your cum!” she begged, her nails digging into my back. “Mia, I’m cumming!” I roared, shooting a hot load of cum deep inside her pussy. She climaxed too—“Oh Ethan, I’m cumming!” Her pussy clenched around me, her juices mixing with my cum as we collapsed together.
We lay there, panting, our bodies tangled. “Ethan, your big cock is everything I wanted,” Mia said in a sexy whisper, kissing my chest. “Mia, your pussy and ass in doggy style were unreal,” I replied, stroking her hair. “I want you to fuck me like that again,” she giggled, her hand brushing my still-hard cock. Since that night, whenever we’re alone, Mia begs for my big cock in doggy style, and I give her exactly what she craves, fucking her senseless until we’re both spent.
