I slammed the front door shut behind me, still pissed from the argument with my girlfriend. The house was quiet except for the low hum of the TV in the living room. My older sister, Rachel, was sprawled on the couch in nothing but a thin tank top and tiny shorts that barely covered her ass. At twenty-four, she had the kind of body that made guys stare—full tits, wide hips, and legs that went on forever. I was twenty-two, and living back home after college had turned every glance into something dangerous.
"Fuck, you look like shit," she said, not even looking up from her phone. Her voice was low and teasing, the same tone she'd used since we were kids, but now it hit different.
"Shut up," I muttered, dropping onto the couch beside her. The cushion dipped, pulling her closer. Her bare thigh brushed mine. Heat shot straight to my cock. We'd always been close, but lately the air between us crackled with something filthy.
She finally looked at me, eyes narrowing. "Girlfriend problems again? You need to get laid, little brother."
I laughed, but it came out rough. "Like you're one to talk. When's the last time you got fucked properly?"
Rachel smirked, shifting so her shorts rode higher. I could see the edge of her panties, already damp. "Why? You offering?"
The words hung there. My heart hammered. I should have laughed it off. Instead I reached over, grabbed her thigh, and squeezed. "Maybe I am."
She didn't pull away. Her hand landed on my lap, fingers brushing the hard bulge in my jeans. "Jesus, you're already this hard? For your own sister?"
I didn't answer with words. I yanked her tank top down, freeing her heavy tits. Her nipples were stiff, dark, perfect. I leaned in and sucked one into my mouth, biting just hard enough to make her gasp. She moaned and shoved her hand into my pants, wrapping her fingers around my thick cock.
"Fuck, your dick is bigger than I remember from peeking," she breathed, stroking me fast and dirty. "You want to fuck me? Say it."
"I want to fuck my sister," I growled, shoving her shorts and panties aside. Her pussy was shaved smooth, lips swollen and slick. I pushed two fingers inside her without warning. She was tight, hot, dripping. "I want to pound this cunt and fill it up."
Rachel spread her legs wider, riding my fingers. "Then do it. Right here. I want my brother's cum leaking out of me."
I stood, ripped my clothes off, and pulled her to the edge of the couch. Her shorts hit the floor. I lined my cock up with her entrance and slammed in balls-deep in one thrust. She cried out, back arching, tits bouncing as I started fucking her hard. No slow build—just raw, wet slapping sounds as I drove into her over and over.
"Goddamn, your pussy's gripping me so tight," I grunted, hands digging into her hips. "You been thinking about this? Your little brother's cock stretching you open?"
"Every fucking night," she moaned, reaching down to rub her clit while I pounded her. "Fill me up. I want that creampie. Don't pull out."
I flipped her onto her stomach, yanked her ass up, and drove back in. The new angle let me hit deeper. Her cunt squelched around me, creamy juices coating my shaft. I reached under and pinched her nipples, twisting until she screamed my name. Sweat slicked our skin.
The smell of sex filled the room.
I felt my balls tighten. "I'm gonna cum in you, sis. Right in this tight fucking hole."
"Do it," she begged, pushing back to meet every thrust. "Pump your sister full. I want to feel it dripping down my thighs."
With a final brutal slam I buried myself to the hilt and exploded. Thick ropes of cum pulsed deep inside her, flooding her pussy. She came with me, walls clamping down, milking every drop. I kept grinding, pushing my load as far as it would go until it started leaking out around my cock.
We stayed locked together, breathing hard. When I finally pulled out, a heavy stream of white cum poured from her stretched cunt, running down her ass and onto the couch. Rachel reached back, scooped some up with two fingers, and licked them clean while looking me in the eye.
"Round two in my bed," she said, voice hoarse. "And this time I want you to fuck my ass after you creampie my pussy again."
I was already hard again. We didn't make it to the bedroom right away.
