I slammed the door behind me after another bullshit day at work. My sister Lena was already home from college, lounging on the couch in nothing but an old t-shirt that barely covered her ass. At 22 she still lived with me while finishing school, and lately the air between us had turned thick and filthy.
She looked up from her phone and smirked. "You look pissed.
Need to blow off some steam?"
I didn't answer with words. I crossed the room, grabbed her by the hair, and yanked her head back so she had to look at me. "You been walking around here half-naked on purpose, Lena? Teasing your own brother?"
Her eyes lit up. "Maybe. You gonna do something about it or just stare at my tits like you always do?"
That was all it took. I shoved her down onto the couch, ripped the shirt up over her head, and spread her legs wide. Her pussy was already glistening. I dropped to my knees, buried my face between her thighs, and licked her from asshole to clit in one long, filthy stroke.
"Fuck yes," she moaned, grinding against my mouth. "Eat your sister's cunt. I've been wet thinking about this all day."
I tongue-fucked her hard, sucking her swollen clit while two fingers pumped inside her tight hole. She came fast, thighs clamping around my head, juices running down my chin. But I wasn't done. I stood up, unzipped, and slapped my thick cock against her pussy lips.
"Beg for it," I growled.
"Shove that big brother cock in me," she panted. "Fuck me raw. Fill me up."
I slammed into her in one thrust. She was so wet I bottomed out immediately, balls slapping her ass. I fucked her like an animal, pounding deep and fast, the couch creaking under us. Her tits bounced with every thrust. I reached down and rubbed her clit while I railed her.
"Harder," she demanded. "Make it hurt. I've wanted this for years."
I flipped her over, yanked her hips up, and drove back in from behind. Her ass rippled every time I bottomed out. I spit on her asshole and worked a thumb inside while I kept fucking her pussy. She pushed back, taking it all.
We moved to the bedroom after the first round. I bent her over the dresser and fucked her standing up, watching her face in the mirror as she came again. Then she dropped to her knees and sucked me clean, gagging on my cock until spit ran down her chin and onto her tits.
"Swallow it all later," I told her. "Right now I want that ass."
She climbed onto the bed on all fours and reached back to spread her cheeks. I worked lube into her tight hole with two fingers, then pressed my cockhead against it. She pushed back and took me slow, groaning as I stretched her open. Once I was buried balls-deep in her ass I started thrusting again, long and deep, while she fingered her own pussy.
We fucked for hours. Missionary so I could watch her face while I stretched her cunt. Cowgirl so she could grind her clit against me and control the pace until she squirted all over my stomach. Doggy again, this time with my hand around her throat while I pounded her from behind.
Every time I got close I pulled out, made her suck me, then switched holes. She begged for cum in her mouth, on her tits, deep in her pussy. I gave her all three. First load down her throat while she swallowed every drop. Second one painted across her tits and face. Third one I pumped straight into her cunt, holding her hips tight so nothing leaked out.
By the time we finally collapsed, the sheets were soaked and her holes were red and used. She curled against me, cum still leaking from her pussy, and whispered, "We're doing this again tomorrow. And the next day. I want my brother’s cock every night."
I slid two fingers back into her messy cunt and started working her toward another orgasm. "Long as you want it, little sister. This pussy is mine now."
We didn't stop until the sun came up.
