Lena stripped off her clothes the second she stepped into the dragon's lair. The air was thick and hot, smelling like smoke and musk. Her tits bounced as she walked straight up to the beast, her shaved pussy already dripping down her thighs. The dragon was huge, black scales gleaming, wings half-spread, and between its legs hung a cock that made her mouth water. It was thick as her arm, veined, ridged along the length, and already leaking thick precum from the slit at the tip.
She dropped to her knees without a word. "Fuck, look at that monster," she muttered, wrapping both hands around the shaft. It throbbed hot and heavy in her grip. She licked from the base up to the head, tongue dragging over every ridge, tasting the salty slick. The dragon rumbled but didn't move, letting her work. Lena opened wide and took the head into her mouth, sucking hard while her hands stroked the rest. Spit ran down her chin as she forced more of it in, gagging when it hit the back of her throat.
Her cunt clenched around nothing. She needed it inside her. Pulling off with a wet pop, she stood and turned around, bending over a smooth rock. She reached back and spread her ass cheeks, showing off her soaked hole. "Come on, big boy. Fuck this hot pussy."
The dragon moved. Its cock nudged her entrance, the blunt head pushing against her folds. Lena pushed back, moaning loud as it stretched her open. Inch by inch it sank in, her cunt lips gripping tight around the ridges. She felt every bump drag along her walls, stuffing her fuller than any man ever had. "Oh shit, yes, deeper," she gasped. Her belly bulged slightly from the size. When it bottomed out she was panting, legs shaking.
The dragon started thrusting. Slow at first, then harder, each stroke slamming her forward against the rock. Her tits swung and her ass rippled every time its hips met hers. Wet sounds filled the cave—slap, squelch, slap—as dragon cock pounded her pussy. Lena reached down and rubbed her clit fast, fingers slipping over the swollen nub. "Fuck me harder, stretch that cunt," she begged. The dragon obliged, driving in balls-deep with each thrust.
She came first, pussy clamping down so tight the dragon growled. Juices squirted around the shaft, running down her legs in streams. But it didn't stop. It kept fucking her through the orgasm, turning it into another one. Lena's eyes rolled back. Her whole body shook. "Don't stop, fill me up," she moaned.

The dragon's cock swelled inside her. Hot cum flooded her womb in thick pulses, so much it overflowed and gushed out around the shaft. It kept pumping, overflow running down her thighs in white rivers. When it finally pulled out, her gaping pussy twitched and leaked.
Lena turned around and licked the cum off the dragon's cock, cleaning every ridge. Then she climbed onto its lap, sinking back down on the still-hard shaft. She rode it hard, bouncing her ass, tits slapping. "This hot sexy girl loves dragon cock," she growled, grinding her clit against the base. Another orgasm hit, then another. The dragon filled her again, cum spraying out with every bounce.
They fucked until dawn. Lena left the cave on shaky legs, cum still leaking from her well-used cunt, already planning her next visit. Her body ached in the best way, marked by the dragon's load. She smiled, knowing she'd be back for more raw dragon cock the second she could walk straight again.
