The forest was thick with the stink of demon blood and sweat when Tanjiro pinned the succubus against the tree. She was no ordinary demon, all curves and glowing eyes, her claws digging into his haori as he ripped her ragged clothes open. Her tits spilled out, heavy and dark-nippled, and he didn't waste time. He shoved two fingers straight into her dripping cunt, feeling how slick and hot she was already.
"Fuck, you're tight for a demon whore," he growled, pumping his hand hard. She moaned loud, hips bucking against his palm. Her juices coated his fingers as he finger-fucked her deep, thumb grinding on her swollen clit. She clawed at his back, tearing his uniform, and he pulled his cock out, thick and throbbing, veins pulsing.

He didn't ask. He just slammed into her in one thrust, burying every inch of his dick inside her wet pussy. She screamed in pleasure, legs wrapping around him as he started pounding. Each stroke was rough, skin slapping, her walls clenching around his shaft like she wanted to milk him dry. Tanjiro fucked her hard against the bark, grunting with every thrust, sweat dripping down his chest. Her demon juices mixed with his pre-cum, making filthy wet sounds echo through the trees.
He flipped her around, bent her over, and drove back in from behind. Her ass jiggled with every slam of his hips. He grabbed her horns, yanking her head back as he railed her cunt mercilessly. "Take it, demon slut," he snarled, reaching around to rub her clit in fast circles. She came hard, squirting around his cock, but he didn't stop. He kept thrusting through her orgasm, chasing his own.
When he pulled out, he spun her to face him again and shoved his slick cock between her tits. She pressed them together, letting him fuck her cleavage while she licked the head on every thrust. He came with a roar, thick ropes of cum painting her face and chest, some landing on her tongue as she swallowed what she could.
But that was just the start of the night. Later, back at the inn, he found Shinobu waiting. The Insect Hashira was naked on the futon, legs spread, fingers already working her shaved pussy. "Heard you had fun," she said with that sly smile. "Now come here and fuck me like the animal you are."
Tanjiro didn't hesitate. He dropped between her thighs and buried his face in her cunt, tongue lapping at her folds, sucking her clit hard. She tasted clean and sweet, but her moans were filthy. He tongue-fucked her until she was dripping down his chin, then climbed up and slammed his cock into her tight hole. Shinobu's legs locked around him as he pounded her missionary style, her small tits bouncing, her nails raking his back.
"Harder, slayer," she hissed. "Fuck me like you fucked that demon bitch." He obliged, driving deep, balls slapping her ass. He flipped her onto all fours and took her from behind, one hand yanking her ponytail, the other slapping her ass red. Her pussy gripped him like a vice, and when she came, she screamed his name, soaking the sheets.
He wasn't done. He pulled out, slick with her cum, and pressed his cock against her asshole. Shinobu pushed back, taking him inch by inch until he was balls-deep in her ass. He fucked her ass raw, slow at first then faster, reaching under to finger her cunt at the same time. Double penetration with his hand and dick had her shaking, coming again, her ass milking his shaft until he filled her with another hot load.
By dawn, both of them were wrecked, cum leaking from every hole, bodies marked with bites and scratches. Tanjiro knew the demons weren't done coming, and neither was he. The slayer life was brutal, but the smuts made it worth every drop.
