I walked into the house after midnight and there she was, my little sister Emma, sprawled on the couch in nothing but a thin tank top and panties. She was twenty-two, legal as hell, and I’d been thinking about her cunt for weeks.
The place smelled like her perfume and a little sweat. She looked up from her phone and smirked.
“Late again, big brother. Mom and Dad are asleep. You want a drink?”
I didn’t answer with words. I crossed the room, grabbed her by the hair, and pulled her mouth to mine. She moaned into the kiss, tongue pushing back hard. Her hand went straight to my crotch and squeezed my already stiff cock through my jeans.
“Fuck, you’re hard,” she whispered. “Been thinking about this all day?”
“Shut up and spread your legs,” I told her. I yanked her panties to the side and shoved two fingers straight into her pussy. She was dripping. Hot, tight, and soaking wet. She bucked against my hand while I finger-fucked her right there on the couch.
Emma reached down and unzipped me. My cock sprang out and she wrapped her fingers around it, stroking fast and rough. “Give it to me. I want my brother’s dick inside me.”
I pulled my fingers out, shoved them in her mouth so she could taste herself, then flipped her onto her stomach. I ripped the panties down her thighs and lined up. One hard thrust and I was buried balls-deep in her cunt. She cried out, loud enough that I clamped a hand over her mouth.
“Quiet, or Mom hears you getting railed by your brother,” I growled in her ear. Then I started pounding. The couch creaked. Her ass slapped against my hips with every thrust. Her pussy gripped me like it never wanted to let go.
She reached back and spread her cheeks wider so I could go deeper. “Harder. Fuck your sister harder.”
I gave it to her. Long, brutal strokes that made her whole body shake. Sweat ran down my back. Her juices coated my shaft and dripped onto the cushions. Every time I bottomed out she whimpered into my palm.
I pulled out, flipped her again, and pushed her knees to her chest. Her pussy was red and swollen, glistening. I slammed back in and watched her tits bounce under the tank top. I yanked the top up so I could suck on her nipples while I fucked her.
Emma’s legs started shaking. “I’m gonna come on my brother’s cock,” she gasped. Her cunt clamped down, pulsing, flooding me with fresh wetness. I kept thrusting through her orgasm, making it last until she was gasping and clawing at my shoulders.
When she stopped shaking I pulled out and stood up. “On your knees.”
She dropped immediately, mouth open. I fed her my cock, still slick with her cum. She sucked like she was starving, taking me to the back of her throat, gagging, spit running down her chin. I held her head and fucked her face until my balls tightened.
I pulled out at the last second and painted her tits and face with thick ropes of cum. She licked what she could reach, then scooped the rest into her mouth with her fingers.
We were both breathing hard. She looked up at me with that filthy little smile. “Same time tomorrow?”
I tucked my cock away and nodded. “Leave the door unlocked. And don’t wear panties.”
She stood, wiped her face with her tank top, and headed for the stairs. Her ass swayed the whole way. I watched until she disappeared, already getting hard again thinking about the next round.
The house stayed quiet. Mom and Dad never woke up. Emma and I kept it going for months after that—quickies in the laundry room, full nights when our parents were out of town, even once in the backseat of my car while parked in the driveway. Every time she called me “brother” while I was inside her it made me fuck her even dirtier.
That’s how it started. Raw. No romance. Just two adults who wanted the same forbidden thing and took it every chance we got.
