I slammed the door behind me and there she was, my little sister Emily, bent over the kitchen table in nothing but a tiny tank top and thong. She was 22 now, all grown up with that round ass I'd been staring at for years. "Took you long enough, big brother," she said, looking back over her shoulder with a dirty grin. "Mom and Dad are gone for the weekend. You know what I want."
I didn't waste time with talk. I grabbed her hips and yanked the thong down. Her pussy was already wet, but I wasn't after that. Not tonight. "You been thinking about this all day?" I growled, spreading her cheeks wide. Her tight little asshole winked at me, pink and clean like she'd prepped just for me.
"Fuck yes," she moaned. "Been fingering it in the shower thinking about your fat cock stretching me open."
I spit on her hole and rubbed it in with my thumb, pushing inside slow at first. She pushed back, greedy for it. "More," she demanded. I spit again, worked two fingers in, then three, stretching that ring while she rocked her hips and cursed. "Goddamn, your ass is so fucking tight. Always has been."
I unzipped and pulled my dick out, already rock hard and leaking. I slapped it against her cheeks a few times, then lined the head up against her asshole. "Beg for it."
"Shove that cock in my ass, brother. Fuck my shithole raw like you own it."
I pushed. The head popped past the ring and she gasped, but she didn't pull away. She shoved back, taking inch after inch until my balls rested against her pussy. "Fuck, yes," she hissed. "All the way. Pound it."
I started thrusting, slow and deep at first, watching my shaft disappear into her ass over and over. Her hole gripped me like a fist, hot and slick from the spit and her own juices dripping down. Every time I bottomed out she moaned louder, pushing back to meet me. "Harder, you pussy. Fuck it like you mean it."
I grabbed her hair and yanked her head back, slamming into her ass faster, skin slapping loud in the kitchen.
Her tank top rode up and I reached under to squeeze her tits, pinching her nipples while I railed her. "This what you wanted? Your brother's dick wrecking your asshole?"
"Yes, fuck, yes. Don't stop. Fill me up."
I pulled out to the tip and slammed back in, over and over, watching her hole gape a little each time I withdrew. She reached between her legs and rubbed her clit, fingers flying. "I'm gonna come with your cock in my ass," she panted. "Keep going, don't you fucking stop."
Her ass clenched around me as she came, body shaking, juices running down her thighs. I kept pounding through it, the tightness milking me. Sweat dripped off me onto her back. I pulled her upright, pressed her against the table edge, and drove up into her from behind, one hand around her throat, the other spanking her ass red.
"Take it," I grunted. "Take every inch in that dirty hole."
She reached back and spread her cheeks wider for me. "Come in me. Flood my ass, brother. I want to feel it leaking out all night."
I buried myself to the hilt and let go, shooting thick ropes deep inside her guts. Pulse after pulse, filling her until it started leaking around my shaft. I stayed inside her, grinding slow while we both caught our breath.
When I finally pulled out, her hole stayed open a second, cum trickling out. She turned around, dropped to her knees, and sucked me clean, licking every drop off my cock like it was her favorite treat.
"Round two in the shower?" she asked, licking her lips.
I grinned and pulled her up. "Get that ass in there. I'm not done with it yet."
