We grew up in the same cramped apartment in the city, me and my half-sister Rosa. Same dad, different moms. Her mom was straight from Mexico, all dark hair and thick hips. Mine was white trash from the block. Rosa turned eighteen two years after me. By then the summer heat had us both half naked most nights, just shorts and thin tanks in the living room with the fan blowing hot air.
I caught her staring at my dick one night when I got out of the shower. It was hanging heavy, half hard from the steam. She didn't look away. "You always walk around like that?" she asked, voice low and direct.
"Only when it's this fucking hot," I said. I didn't cover up. Her eyes stayed on it. Her nipples poked through her tank top, dark circles showing through the white cotton.
She stood up and walked over. No bullshit, no slow talk. She grabbed my cock right there, fingers wrapping around the shaft. "This what you want, hermano? Your own sister stroking your dick?"
"Yeah," I said. My voice came out rough. "Squeeze it harder."
She did. Her hand pumped me slow at first, then faster. Pre-cum leaked out and she smeared it over the head with her thumb. I reached under her tank and grabbed her tits. They were heavy, warm, nipples stiff between my fingers. I pinched one and she moaned, low and dirty.
We didn't make it to the bedroom. She dropped to her knees on the living room floor and took my cock in her mouth. No teasing. She sucked hard, lips stretching around the thickness, tongue working the underside. Spit ran down my balls. I held her head and fucked her face, pushing deep until she gagged. She pulled off just long enough to say, "Choke me with it. I want to taste my brother's cum."
I pulled her up instead. Bent her over the arm of the couch. Yanked her shorts down. Her ass was round and brown, pussy already wet and glistening between thick thighs. I spit on my fingers and rubbed her clit, then shoved two inside. She was tight and hot. "Fuck, you're soaked," I said. "You been thinking about your brother's cock all day?"
"Every day," she answered.
"Now put it in."
I lined up and drove straight in. One hard thrust buried me to the balls. She grunted, pushing back against me. I fucked her rough, skin slapping, her juices coating my shaft. Her pussy clenched every time I bottomed out. I reached around and rubbed her clit in fast circles while I pounded her.
She came first, legs shaking, pussy pulsing around my cock. She kept talking dirty the whole time. "That's it, fuck your sister's cunt. Fill it up. I want your load dripping out of me."
I didn't last long after that. I slammed in deep and unloaded, thick ropes of cum pumping into her. She milked every drop, grinding back until I was empty.
We didn't stop there. After that night it became regular. Mornings before dad woke up, she'd sneak into my room and ride me, tits bouncing, whispering how wrong it was and how good my cock felt. Afternoons when the apartment was empty she'd bend over the kitchen table and I'd eat her pussy from behind, tongue fucking her until she begged for dick again.
One weekend we had the place to ourselves. She wore nothing but an old T-shirt of mine that barely covered her ass. I bent her over the sink while she washed dishes and fucked her standing up, water splashing everywhere. Later on the couch she got on all fours and I took her ass for the first time. She was tight there too. I worked lube in with my fingers first, then pushed my cock in slow until her hole stretched around me. She fingered her own pussy while I fucked her ass, coming hard with my name on her lips.
We kept it raw and simple. No romance talk, just fucking. She liked when I called her my dirty sister. I liked when she told me how much better my cock was than any other guy. We'd fuck in the shower, against the wall, on the floor when we couldn't wait. Cum on her tits, in her mouth, deep in her pussy. She'd walk around after with my load leaking down her thigh, smiling like she owned it.
By the end of that summer we had it down to a routine. Every night after the lights went out she'd come to my bed. Sometimes slow and deep, sometimes fast and hard. Always explicit. Always her telling me exactly how she wanted it and me giving it to her. No one else knew. It stayed between us, hot and filthy and exactly what we both needed.
