The demon slayer kicked the door open and charged into the abandoned shrine, sword drawn, breathing hard from the chase. Her name was Lena, twenty-three and built like she lived on the road—lean muscle, small tits that barely bounced under her uniform, and a shaved pussy that stayed wet from adrenaline alone. The demon waited inside, tall and shirtless, horns curling back from his head, cock already half-hard and thick against his thigh.
"Thought you could hide, asshole?" Lena spat, swinging her blade. The demon dodged and grabbed her wrist, slamming her against the wall. "Feisty little slayer bitch. You smell like you want it."
She kneed him in the gut but he pinned her arms above her head with one hand. His free hand ripped open her uniform top, exposing her nipples to the cold air. He pinched one hard and twisted. Lena hissed, then moaned when he shoved his knee between her legs and ground it against her clit through her pants.
"Fuck you," she growled, but her hips rocked forward anyway. The demon laughed low and yanked her pants down to her ankles. Her pussy was already dripping, lips swollen and shiny. He dragged two thick fingers through her folds and shoved them straight inside, knuckle-deep, pumping fast and rough.
Lena's head thumped back against the wall. "Deeper, you bastard." He added a third finger and curled them, rubbing that spot that made her thighs shake. Her juices ran down his hand. He pulled his fingers out, shoved them into her mouth, and made her suck them clean while he freed his cock—long, veined, ridged like a demon's should be.
He spun her around, bent her over a broken altar, and kicked her legs apart. One hard thrust buried him to the balls in her tight cunt. Lena cried out, pushing back to take every inch. The demon fucked her like he wanted to break her—deep, slamming strokes that slapped his heavy balls against her ass. Her tits dragged against the wood with every thrust.
"Take it, slayer cunt," he snarled, gripping her hips hard enough to bruise. "This pussy was made for demon cock." Lena reached back and spread her ass cheeks wider, letting him pound even deeper. Her clit throbbed untouched, but the stretch and the filthy slap of skin on skin was enough. She came hard, cunt clamping down and squirting around his shaft, but he didn't stop.
He flipped her onto her back on the altar, hooked her knees over his shoulders, and drove back in. The new angle hit her g-spot every time. Lena clawed at his chest, leaving red lines. "Harder. Ruin me." He obliged, pounding until the altar creaked. Her second orgasm hit with a scream, pussy pulsing and milking him.
The demon pulled out, flipped her again, and hauled her onto his lap as he sat on the floor. She sank down on his cock in one motion, riding him reverse cowgirl while he reached around to rub her swollen clit in tight circles. "Fuck, yes—use that demon dick," she moaned, bouncing hard, ass rippling. He slapped her ass red and thrust up to meet her.
They switched again. He stood, holding her in the air with her legs wrapped around him, and fucked her standing, gravity driving her down onto every thick inch. Her juices coated his cock and dripped to the floor. Lena bit his shoulder when she came the third time, body shaking.
He dropped her to her knees and shoved his cock into her mouth.

Lena sucked greedily, tasting herself, taking him to the back of her throat while he fucked her face. Spit ran down her chin onto her tits. When he pulled out, he painted her face and open mouth with thick ropes of cum. She swallowed what she could and licked the rest off her lips.
The demon hauled her up, bent her over once more, and slid back into her cum-slick pussy for a final rough round. He fucked her until she was hoarse from moaning, until her legs gave out and he had to hold her up by the hips. His second load flooded her deep, overflowing and running down her thighs.
They collapsed in a sweaty heap on the shrine floor. Lena's sword lay forgotten a few feet away. The demon's hand rested possessively on her ass.
"Round two when you can walk again, slayer," he muttered.
Lena grinned against his chest, already feeling her cunt twitch at the idea. "Bring it on."
