I slammed the door behind me and there she was, my sister Emily, bent over the kitchen counter in nothing but a tiny tank top and panties, her ass cheeks spilling out like she knew exactly what she was doing. "Took you long enough to get home, big brother," she said without turning around, voice low and filthy. "Mom and Dad are gone for the weekend. You gonna stand there staring or come over here and fuck me like you always talk about?"
My cock was already rock hard in my jeans. I crossed the room in three steps, grabbed her hips, and yanked those panties down. They were soaked. "You've been waiting for this, haven't you?" I growled, sliding two fingers straight into her wet pussy. She moaned and pushed back against my hand. "Yes, fuck, finger that cunt. I've been dripping all day thinking about your dick."
I unzipped, pulled out my thick cock, and rubbed the head up and down her slit. "Say it. Tell me you want your brother's cock inside you." Emily looked back over her shoulder, eyes dark. "I want my brother's cock. Shove it in me right now." I slammed into her in one thrust. She was tight and hot and perfect, gripping me like she never wanted me to pull out.
I started pounding her against the counter, skin slapping loud, her tits bouncing with every stroke.
"Fuck yes, harder," she gasped. "Use that pussy. It's yours." I reached around and rubbed her clit while I fucked her deep, balls slapping her ass. She came fast, screaming my name, her walls squeezing my shaft. I didn't stop. I flipped her around, lifted her onto the counter, and buried my face between her legs, licking and sucking her swollen clit until she was shaking again. "Taste good, sis?" I asked, standing up and sliding back inside her.
We moved to the living room couch. She rode me reverse, grinding down hard while I smacked her ass red. "Tell me how much you love fucking your brother," I ordered. "I love it," she panted. "Love your big cock stretching my cunt. Fill me up." I grabbed her hair and pulled her back against my chest, pounding up into her until I exploded, shooting thick ropes of cum deep inside her. She kept grinding, milking every drop.
Later we didn't even bother getting dressed. We fucked in the shower, her on her knees sucking me clean then swallowing my second load. Then on her bed, doggy style, me pulling her hair and calling her my dirty little sister slut while she begged for more. By morning we were still at it, lazy and slow on the kitchen floor, her riding me while I sucked her nipples and told her this was just the start of the weekend.
We spent the whole two days naked, fucking wherever we wanted. On the dining table, against the front door, in the backyard at night with her bent over a lounge chair. Every time she came she moaned about how good her brother's cock felt. Every time I came I pumped her full or painted her tits or made her lick it off. No guilt, no stopping, just raw, nasty family fucking until we were both sore and satisfied.
