The sun was already high when I climbed the ladder into the loft, sweat sticking my shirt to my back. I figured I'd be alone stacking bales, but there she was—my older sister, Jenna, twenty-four and looking every bit of it in cut-off shorts and a tank top that barely covered her tits. She turned when she heard me, a smirk on her face that said she knew exactly what kind of trouble we were about to get into.
"Thought you'd never show," she said, wiping hay dust off her hands. "Dad's gone to town. We're clear for a couple hours."
I dropped the pitchfork and crossed the loft in three strides. No slow shit, no talking it to death. I grabbed her by the hips and yanked her against me, my cock already hard and pressing into her stomach. "Shut up and get those shorts off."
Jenna laughed, low and dirty, then shoved her shorts down her legs. No panties. Her pussy was shaved smooth, lips already glistening.
She kicked the shorts aside and pulled her tank top over her head. Her tits bounced free, nipples dark and tight. I spun her around, bent her over a stack of hay bales, and kicked her feet apart.
"Fuck, look at that ass," I muttered, slapping one cheek hard enough to leave a red handprint. She moaned and pushed back. I unzipped, hauled my cock out, and dragged the head through her wet slit a couple times before slamming in balls-deep on the first thrust.
She cried out, loud and raw. "Yeah, fuck me like that. Harder."
The hay scratched her knees and palms but she didn't care. I gripped her hips and pounded into her, the wet slap of skin on skin echoing off the barn walls. Her cunt squeezed me tight, hot and slick, taking every inch. I reached around, found her clit, and rubbed it rough and fast while I fucked her.
"Don't stop," she gasped. "I'm already close."
I didn't. I hammered her until her legs shook and she came with a shout, pussy pulsing around my cock, juices running down her thighs. I pulled out, flipped her onto her back on the bales, and shoved back in. Her tits bounced with every thrust. I leaned down and sucked one nipple hard, biting just enough to make her yelp.
"Put it in my mouth," she demanded when I pulled back. I climbed up, straddled her chest, and fed her my cock. She sucked it like she was starving, tongue working the underside, taking me deep until she gagged. Spit ran down her chin. I fucked her face for a minute, then pulled out and slid back between her legs.
This time I went slower but deeper, grinding against her clit on every stroke. She wrapped her legs around me, heels digging into my ass. "Fill me up," she whispered. "Come inside your sister."
That did it. I slammed in one last time and unloaded, thick ropes of cum pumping into her. She came again right after, milking me dry. We stayed locked together, breathing hard, hay sticking to our sweaty skin.
After a minute she grinned up at me. "Round two in the truck bed later?"
I pulled out, watching my cum drip out of her. "Hell yes."
We cleaned up quick, got dressed, and went back to work like nothing happened. But every time our eyes met the rest of the day, we both knew the loft was waiting for us again tomorrow.
