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.

Kat Denholm sat in her father's library, sipping at the mug of tea he'd made her, occasionally glancing over at him as he sat in the chair opposite her own. He in turn could hardly take his eyes off her. Overnight she'd gone from being a slightly overweight young woman who, if he was honest, was somewhat plain looking to the almost quintessential pornstar. Her ass was big, round and firm and only just covered by the only skirt she owned that still fitted her - - her waist was tiny and only accentuated the size of her new boobs which formed the other half of her new hourglass figure. They were huge and round yet appeared to be firm and sat high on her chest, covered as they were by a tight T-shirt.
If he hadn't seen her just three days before, he would swear she'd had plastic surgery done.
And, as much as he tried to ignore it, he had to admit her new look was turning him on.
"So," he said, partly in an effort to distract himself from his daughter's body. "Tell me what's happened to you and Dr McAllister."
Kat sighed and placed her mug on the small table beside her chair. "Me and Dr McAllister were in the basement of the Academy, cataloguing old specimens. I found a box that contained some sort of fungus with two ball shaped growths on the surface. Some sort of vine or tentacle leapt out of the box and started to strangle me; when Dr McAllister came to help, the same thing happened to her. The two ball shaped things hovered in front of our faces and as the vines let go and we caught our breath, the balls opened and spat out some type of spores which we breathed in before we both passed out."
Kat wrapped her arms around herself as best she could with her new, huge tits in the way, and shuddered, remembering the previous day's events.
"We were unconscious all day and when we woke up, we headed to our homes. Then, about lunch time, I woke up and found myself - - well, like this."
Without thinking, she cupped her big tits to emphasize the change that had come over her and shuddered again, this time in pleasure, her hands on her huge tits making her nipples stiffen immediately, poking against the stretched-thin material of her T-shirt. She felt her pussy heat up and moisten, too, faster than it ever had before. Kat gasped in surprise and delight at the feelings and would have continued touching herself had her father not coughed to get her attention.
"Oh - - oh shit, sorry, Dad," she said, taking her hands away from herself, blushing with embarrassment.
"Go on with your story, darling," he said, subtly rearranging the bulge in the front of his trousers.
"Well - - I figured it had something to do with the fungus so thought Dr McAllister might be affected, too. She rang me, though, as I was about to ring her and asked me to go over to her house. I did and sure enough she looked just like me. We were - - we were about to - - well, I mean,"
"It's okay, darling," her father said, sensing her hesitation. "You can tell me."
"We - - I think we would have - - had sex, but she mentioned something, a name, and when I didn't recognise it, she flipped, grabbed a knife and attacked me. She tripped, though, and fell on it, on to the sofa. All that ash you saw on the sofa? That was blood, Dad."
"Blood that turned to ash?" her father said. "The name she mentioned - - can you remember it?"
"It was something like - - No'nehog - - No'nehogtath? She also called him the Lord of the Fungus." She watched her father stand and head towards the free standing bookshelves, scanning the books that covered them. "Does that mean anything to you, Dad?"
Her father didn't answer but just scoured the shelves, pulling out a book and flipping through it for a moment before putting it back, repeating it with another and another. Eventually he returned to his seat carrying two books, one a modern hardback with a tattered and torn dust jacket, the other an old, leather bound volume with pages of parchment.
"Dad? Did you find anything?" Kat asked.
"The name sounded familiar," her father said, putting the books on the table in front of them and flipping through the pages. "As you know, I studied ancient religions and mythology in university, and my studies took me all over the world. No'nehogtath was worshipped by islanders in the Pacific and, at the turn of the last century, by a group of degenerates who were based not far from here."
He tapped one of the books and Kat moved, sitting on the floor between his chair and the table, letting him lean over her to point things out.
"No'nehogtath was supposedly a minor god in one of the old Pacific pantheons, minor but still powerful. It was said he would possess women by means of his spores and alter their bodies, turning them into the Brides of the Fungus."
He pointed to a reproduction of a wood carving that showed half a dozen crudely drawn women surrounding a large, vegetable mass. Each of the women had inflated breasts and asses and were being penetrated by tubular appendages that grew from the central bulb.
"These Brides would use their bodies to seduce men which No'nehogtath would feed upon, building his power until he could summon his brethren from some other world. Apparently, once infected, the women would be under his power until death." He reached for the other, older book, pointing out another section. "Death could come to them only with the removal of No'nehogtath's seed from within them."
He pointed to another, even cruder drawing, this time showing a woman with an hourglass figure whose stomach had been cut open. A priest stood beside her, holding up something that looked like a large sunflower seed, about the size of his hand.
"Oh god - - I've got one of those things inside me?" Kat asked.
Her father shrugged. "Who knows? Something's obviously happened to you and, from what you said, Dr McAllister. Everything you've said fits with the legends of No'nehogtath. The only difference is that you said Dr McAllister was obviously under the influence of something, supposedly No'nehogtath itself, while you're not." He looked down at her where she sat between his outstretched thighs and stroked her dyed, blue hair. "If we can find out why she was affected and you weren't, we might be able to find a cure for her."
Kat sighed, closing her eyes and leaning back against her father's chair, loving the feel of his hands on her hair. She turned her head slightly, guiding his hand down her cheek and on to her neck, moaning softly as he stroked her skin, his other hand moving over the other side of her face. He moved lower, across her shoulder, his hand sliding under the thin T-shirt she wore, heading down towards the swell of her breast.
"Mmmmm - - feels nice," she sighed, opening her eyes as her father snatched his hands back.
"Oh God - - Kat, I'm sorry - - I don't know what came over me," he gasped, his face going red with embarrassment.
"It's okay, Dad," she said, turning round and kneeling up, her huge tits resting on his thighs. "I - - I don't know why but - - but I didn't want you to stop." She ran her hands up his legs and across his stomach, meeting at his belt buckle which she toyed with. "I still don't want you to stop," she said quietly, staring up at him.
"Kat - - I don't - - I'm not sure we should - - I mean," he stuttered, his gaze moving from her face to her huge tits that were ballooning out of the neckline of her T-shirt.
"You like my new big titties, don't you Daddy?" Kat asked suddenly. "I can tell you do. You can't keep your eyes off them, can you Daddy?" She popped open his belt buckle and started opening his trousers. "Would you like to see them? Would you like to touch them?"
"Oh Kat - - no, we - - we can't - - you're my daughter,"
"So what, Daddy?" She opened his trousers and ran her hand across the obvious bulge of his large, hard cock. "I can see you want me. Can't you tell I want you too?"
"It's the fungus - - it's affecting your mind - - your desires," he gasped, watching as she pulled his boxer shorts down over his boner.
"Maybe it is, Daddy," Kat said, leaning down and running her tongue along the length of his big dick, giggling as she felt it buck beneath her. "But that's my excuse. What's yours for having such a big hard-on?" She lifted it up and took the head of her father's dick in her mouth, sucking at it, the rosy cock knob spurting out pre-cum which she slurped down.
"Oh God - - I'm only - - human," he gasped, reaching down and filling his hands with her huge tits as she bobbed her head up and down on his cock. They felt firm and pliable as he squeezed and groped at them, tearing open her thin T-shirt at the neck so he could get both hands on her mounds of tit-flesh. "So big - - so fucking big," he groaned.
Kat sat up and tore off the remains of her T-shirt, took hold of her huge tits and wrapped them around her father's cock. Instantly he started moving his hips, sliding his big dick between her jugs, tit fucking his daughter as she held her massive mounds together, enveloping his length in her cleavage.
"Oh yes - - oh yes," he sighed, watching his dick appear and disappear from between her tits. "Always - - always wanted to do this - - never - - never able to - - before."
In the back of her mind, Kat knew he was talking about her mother who had been as flat chested as she had been before the fungus and who had died when Kat was a teenager.
"Now you can, Daddy," Kat sighed. "Now you can fuck my titties whenever you like."
Her father groaned as he thrust his cock up and down between her huge, round melons, loving the warmth and smoothness of her new tits against his dick.
"Do you want to fuck me, Daddy?" Kat asked. "Do you want to fuck your daughter's tight little pussy?"
Without waiting for an answer, Kat stood, laughing as her father moaned in disappointment as his dick fell free of her tits. She pulled her skirt up around her waist and straddled her father in his chair, reaching down and taking hold of his cock. She held it upright and slid her bald, wet pussy lips over his knob before slotting into the entrance of her twat. Slowly, watching her father watching her cunt, she moved lower, his knob parting her juicy cunt lips as she eased herself down over him.
