The cave reeked of musk and old stone when I shoved my snout between my father's scaled thighs. At twenty-eight I was no hatchling, but the first time his thick dragon cock had slapped against my belly three years ago still burned in my memory like fresh fire. Tonight he wanted more. His golden eyes glowed in the dark as he growled low, claws digging into my shoulders to pin me down on the warm rock floor.
"Open that mouth, boy," he rumbled, voice like grinding boulders. His cock was already half out of its slit, black and ridged, the head flared and leaking thick pre that smelled like smoke and salt. I didn't hesitate. My own shaft throbbed between my legs, hard and dripping onto the stone. I licked up the underside of his length, tasting the bitter heat of him, then swallowed the head with a wet gulp.
He hissed and thrust, driving half his cock straight down my throat. I gagged but held on, tongue working the ridges while my claws gripped his heavy balls. They swung low, full and tight, the same heavy orbs that had made me. Saliva ran down my chin and dripped onto my chest scales. He fucked my face in short, brutal strokes, the wet sounds echoing off the cavern walls.
"Take it deeper, son. Show your old man what that mouth learned." His tail lashed around and smacked my ass hard enough to sting. I moaned around his cock, the vibration making him buck harder. My own dick ached untouched, the tip smearing pre across my belly.
When he pulled out I gasped for air, strings of spit connecting my lips to his glistening shaft. He flipped me onto my belly with one powerful shove and hauled my hips up. His tongue, rough and hot, dragged over my hole without warning. I roared at the sudden invasion, claws scraping stone as he licked and spat, getting me sloppy wet.
"Fuck, Dad," I panted. "Do it. Breed me like you did last moon."
He didn't waste time with words. The blunt head of his cock pressed against my hole and pushed. The stretch burned sweet and deep, ridges popping past my ring one by one until he was buried to the root. My walls clenched around every inch. He started thrusting immediately, long powerful strokes that jolted my whole body forward. Each slam drove the air from my lungs and made my cock slap against my stomach.
His claws raked down my back, not hard enough to draw blood but enough to mark. "Tight little dragon cunt," he snarled. "Still so greedy for your sire's load." He reached under me and wrapped a big paw around my cock, stroking in time with his thrusts. Pre poured over his fingers. The wet slap of scales on scales filled the cave along with our grunts and the squelch of his cock pounding my hole.
I came first, roaring as my cock pulsed in his grip. Thick ropes of cum splattered the stone beneath me, my ass clenching rhythmically around him. He didn't stop. He fucked me straight through it, using the extra slick to hammer harder until his knot started to swell at the base.
"Take it all," he growled, and shoved the knot inside with one final thrust. It locked us together as he came, flooding my guts with hot, heavy spurts. I felt every pulse, his cock jerking inside me, cum leaking out around the knot and running down my thighs. He stayed buried, grinding slow circles while he emptied, one paw still lazily milking the last drops from my spent cock.
We stayed knotted for a long time, breathing hard, his chest pressed to my back. When the knot finally deflated enough to slip free, a gush of his cum followed, splattering between my legs. He turned me over and licked my face clean, then kissed me deep, sharing the taste of our mixed seed.
"Rest," he said against my snout. "Round two when the moon rises again."
I grinned, already feeling my cock twitch back to life against his thigh. The night was young, and so were we.
