This is filed under Erotic Horror because as it goes along, it'll feature gruesome deaths and violence. It will, though, heavily feature incest, big tits and big dicks like most of my stuff, along with non-human magical creatures. If none of that is what you're after, don't bother continuing from here.
And, as always, everyone involved is at least 18.

Kurt Denholm sat in his large bed, flicking through the pages of an old book, a look of frustration on his face. Beside him, curled up against his muscular torso, lay his daughter Kat, fingers flicking over the screen of her iPad.
"It's no good," Kurt said. "I can't find anything about a cure for the condition, other than by removing this mysterious seed the accounts talk about. And in every case - that ends in death."
"Not much of a cure, dad," Kat said. "And I hope you're only talking about a cure for Dr McAllister. I'm quite happy with my new look." She reached under the covers and hefted her father's heavy, thick cock. "And I'm very happy with yours as well."
Kurt grinned and dropped the book on to the floor, slipping one arm around her shoulders, the other pushing the covers down, revealing and the cupping her huge tits.
"Couldn't agree more, baby," he said.
"Ah shit," Kat said.
"Not the reaction I was expecting," Kurt said.
"No, not you, dad, this." She pointed at her tablet which showed an article from the website of the Wilbraham Sentinel, the local newspaper. The headline read SIX ACADEMY STUDENTS, ONE DOCTOR MISSING.
"Is the doctor your boss?" Kurt asked.
"Yeah," Kat said. "Dr McAllister hasn't been at the Academy since we were attacked by the fungus last week," she said, paraphrasing the article. "Since then, six students have gone missing, four boys and two girls - shit! Dad, one of the girls who's gone missing, it's Jennifer Rabaiotti, the girl Dr McAllister mentioned to me before she realised I wasn't possessed by that thing that's got her."
"You said she wanted to use that girl to recruit others, other brides for the fungus?"
"Yeah," Kat said. "Dad, it looks like she's really going through with this, trying to get more brides for No'nehogtath. While we've been fucking our brains out for the last week, she's been luring boys to sacrifice to that fungus god."
Kurt pulled her closer. "Not your fault, baby," he said. "We've been looking for a cure for Dr McAllister as well, and if we can find a way to help her without killing her then we will."
"But shouldn't we have spoken to the police or something?"
"You know they wouldn't believe us, Kat," he said. "At the least they'd think we were crazy, at worst they'd lock us up. Probably the latter if they found out we'd been having sex together."
"Yeah, I guess," Kat said. She cuddled up closer to her father's broad chest, her hand lazily stroking his big dick, feeling it slowly harden in her hand. "As much as I want to help Mia and wish this crazy shit hadn't happened, I'm really glad you and I ended up like this. You know, pornstar bodies and sex drives."
"Mmmmm, me too," Kurt said, running his hand over her big, round tits again, feeling her small nipples harden beneath his fingers. As she lifted her head, he bent his down and they kissd, tongues slipping into each other's mouths. She smiled up at him as she broke the kiss, pushed the covers to one side and bent down, stuffing as much of his half hard cock into her mouth as she could.
Kat purred as she sucked and gently chewed on the tough stalk of his meat, her head being forced up as it grew bigger and harder in her mouth. She drooled all over it, spit sliding down the shaft which she used as lube to ease the motion of her hand as she slid it up and down the thickening trunk of his cock.
"Aahhhhhh, fuck yeah," Kurt sighed, bunching his hand in her dyed blue hair, gently guiding her as she bobbed her head up and down. "That's it, baby - suck Daddy's cock."
Had her mouth not been crammed full of his dick, she would have smiled. Only a week ago he'd been racked with guilt after they'd first had sex but since his own transformation in to a muscular, big dicked and slightly younger version of himself, he'd happily thrown all concerns to the wind.
"Yeah, suck my dick - suck Daddy's big dick," he murmured, sliding his free hand over Kat's back and down her side, grabbing a handful of her huge tits that, despite their size, still managed to be firm and sit high on her chest. "Get it nice and wet, baby," he grunted, pushing his hips up, thrusting into the back of her throat.
"AAGGLLLL! KKLLLL! MMMPPPHFLLL!" Kat coughed and gargled as her father's cock pushed beyond her mouth and into her throat, something she never would have been able to take before the fungus had changed her. Now she loved feeling his hard shaft deep inside her, spit dribbling down its length as the big, bulbous head slid in and out of her throat.
Kat reared back, thick lines of spit connecting her lips and his cock head for a moment before they broke, covering her father's dick in saliva. She fisted his hard length for a moment before looking up at him and smiling.
"Your dick's all wet and slippery, Daddy," she said. "You know where I want it?"
"Where, baby?" Kurt asked with a grin.
She rolled on to her back, her head on the pillow, and cupped her huge, round tits, mauling them as she mashed them together.
"Put it between my titties, Daddy," she said, spreading her big jugs apart. "Come fuck your daughter's big fucking titties."
Kurt quickly climbed over and straddled her, holding his steel hard cock down so that Kat could wrap her big tits around it, the head just peeping out from her deep cleavage. While his late wife - Kat's mother - had been small breasted, he'd secretly always had a thing for big tits. Since his and Kat's transformations he had eagerly indulged his fetish to the delight of his daughter.
He slid his cock along the valley between her tits, sighing as he felt and watched her lick and suck at the head of his dick as it popped out on his up thrusts, Kat's tongue lashing around it before she clamped her lips around the rosy knob.
"Ahhh yeah - yeah, that's it, baby," Kurt groaned. "Love your tits - Daddy loves your big - fucking - tits."
"Mmmmm - and I - love your - big cock - Daddy," Kat said between sucks.
Kurt reached down and took hold of his daughter's enormous tits, holding them in place as he thrust his cock in and out of her cleavage, titty fucking her with long, slow strokes, just the way they both liked it. His cock bucked as it was wrapped in the fleshy pillows, spurting out thick lines of clear pre-cum that helped lube the motion of his dick and filled the bedroom with the slick sounds of their tit fuck.
"Can I - can I fuck your pussy now, baby?" Kurt asked after a few minutes.
