The old barn smelled of hay and musk the night I finally gave in. I was twenty-three, bored on my uncle's farm, and the big black shepherd mix named Rex had been following me everywhere for weeks. His eyes locked on me every time I bent over to feed the horses. One hot evening after a few drinks alone in the loft, I stripped down to nothing and called him over. Rex came fast, tail wagging, nose already pushing between my thighs like he knew exactly what I wanted.
I spread my legs on the blanket and let his rough tongue drag over my pussy. It was wet, insistent, and hotter than any guy I'd been with.
I moaned loud, hips rocking against his muzzle while he licked deep, lapping up every drop of my growing wetness. "Good boy," I whispered, reaching down to stroke his thick sheath. His red cock was already sliding out, slick and veined, the knot starting to swell at the base. I wrapped my fingers around it and pumped, feeling it throb and grow until it was heavy in my hand.
Rex mounted fast once I got on all fours. His front paws gripped my hips hard, claws pricking skin. The tip of his cock jabbed blindly until it found my soaked entrance and slammed inside in one rough thrust. I cried out, the stretch intense and perfect. He fucked like an animal, fast and brutal, driving that cock deep into my cunt with every stroke. My tits swung under me, nipples brushing the blanket. Wet sounds filled the barn as he pounded me, his balls slapping my clit.
I came hard the first time, pussy clenching around his shaft, but Rex didn't slow. He kept hammering until the knot swelled and pushed against my opening. I pushed back, wanting it, and felt the thick bulge stretch me wider until it popped inside. Locked together, Rex gave short, grinding thrusts while his cock pulsed and flooded me with hot cum. It leaked out around the knot, running down my thighs in thick streams. I rubbed my clit through another orgasm, shaking and whimpering his name.
We stayed tied for twenty minutes, his body heavy on my back, tongue lolling against my neck. When the knot finally deflated I pulled off slowly, cum gushing from my well-fucked hole. Rex licked me clean, tongue working over my swollen pussy and ass until I was ready again. I rolled onto my back this time, legs wide, and guided his cock back into me. He fucked me missionary style like a lover, eyes locked on mine, hips snapping fast until he knotted me a second time.
By morning my thighs were sticky and sore, but I was already planning the next night. The farm had three more dogs, and the stories I'd read online were nothing compared to the real thing. Rex watched me dress with possessive eyes, already waiting for his next turn.
