Chapter 1 - Belphegor

“For fuck’s sake, Gabriel,” Lucy’s exasperated voice rang out from the kitchen, “Have you seriously eaten the ganache I made this morning? That was for customers' cakes!”

Gabe startled awake from his nap. There had been a time, not too long ago, when he had been full of energy, athletic, fit and enthusiastic. But that was before. Now he always needed to take a nap in the early afternoon - he needed to sleep off his breakfast… second breakfast… brunch… lunch… And his afternoon snack, which today had indeed been a large bowl of rich chocolate ganache. He knew it was for the customer’s cakes, of course - Lucy had stopped making so many sweet treats for him to eat nowadays out of concern for his health - but that hadn’t stopped him from guzzling it down, not even stopping to grab a spoon but simply using a spatula which had been close to hand. Again, there had been a time when the idea of doing anything that might inconvenience Lucy would have been a shade beyond the pale for Gabe. Eating the ingredients for her bakery would have been unconscionable...

But that was before Belle.

***

Gabe had no idea how he had managed to summon a demon in his girlfriend’s kitchen, but there was no denying that it had happened. He’d seen it with his own eyes, and the physical effects were irrefutable. It had happened the night before Halloween, almost a year ago. Lucy had decorated the bakery with skeletons, witches, vampires and other dark creatures, and had spent the day icing cakes and cookies with spooky designs. She had gone out on a delivery and Gabe had been left at the shop, cleaning up. He hadn’t managed to get much further than licking cake batter off the mixing bowls and tooling around on his phone, though, feeling a little annoyed that he had drawn the short straw and been stuck cleaning. It had reached 23:59 when he had found himself leaning against the counter, idly drawing patterns in a puddle of confectioner’s sugar that was left behind. He was copying one of the posters Lucy had put up. As the hour had struck midnight, his sticky, sugary finger completed the pentagram, and all of the bakery lights had gone out at once.

“Shit,” he’d muttered, annoyed, and he’d made his way over to the circuit breaker, knocking his shins on what felt like every bit of furniture as he did so.

When the lights came back on, Belle had been standing there. She was tall and impossibly curvy - she looked almost a parody of everything that his mind found attractive. A faint energy seemed to radiate from her body - he fancied he could hear it buzzing as she drew closer to him. Gabe had known from the second he had seen her that she was not of this world, that she was darker, abyssal, wrong. But he had been unable to speak in her presence, unable to think, and she had been on him before he could even process what was happening. One minute he had been standing, shocked, by the fusebox in the kitchen pantry. The next minute he had been sprawling on the floor as she bowled him over, her hands ravaging his body and her hot, forked tongue almost burning his neck as she ran it from his collar bone to the soft, vulnerable pulse point of his jugular. Her eyes were completely black, and they sparkled like polished onyx, drawing him in. As her strange flesh slipped onto his cock he had felt himself falling into the pits of those eyes. His hands had tightened at her tiny waist and he had thrusted and thrashed underneath her as rapturous pleasure boiled at every nerve ending of his body.

Then it had been over. She was gone.

And he had begun to eat.

***

He had ballooned in the past year. His body had been lost to Belle’s influence, piles of jiggling fat covering every once discernable feature he’d once had. It had started off small, hearing her whispering to him when he passed fast food joints and hotdog stands, tempting him to buy snacks at work on top of the healthy lunches that Lucy packed for him. When he tried to ignore her, she needled at his thoughts, manifesting on Lucy’s cake displays with her legs spread apart and perching on bar counters, encouraging him to get round after round in when his friends were ready to tap out. She commanded his attention, making his head buzz and spin when he tried to ignore her, making food the only comprehensible thought he could focus on. But when he was good, when he did not fight it, when he allowed her to lead his swelling body straight to more food… well. Her rewards were swift and immediate.

Her hands, unseen to anyone he was with, would massage his gut as he ate, fending off the inevitable stomach aches and allowing his binging to last for so much longer than should have been possible. Her whispers would drip like honey into his ears. “Gorgeous man, sweet greedy human… you’re coming along so nicely… eat more for me, sweetling… sin with me…” It was incessant. When he staggered to bed, his belly standing out a couple of feet from his body and hard as rock, she would manifest there as well, and she would allow him to use her profane body until he was a quivering wreck, the pleasure centres in his brain firing like supernovas.

As his shirt tags collected Xs and he began to take up more and more room on the couch, Lucy had expressed her concerns. She had tried everything to bring him back around, but there was no stopping him. He was possessed. When she banned him from eating from her bakery, finding that half her stock was being devoured before she could put it in the shop, she had come home to find him gorging on pastries from her main competitor. That had been a terrible argument - he had to have spent nearly £100 on cannoli and eclairs - and as much as he had tried to explain through his cream streaked lips that it hadn’t been anything personal, he knew that it wasn’t entirely true. Belle’s impish grin when she had pointed him towards the rival shop spoke of spite and malevolent desire as well as gluttony. She was revelling in it. She was corrupting him.

***

Lucy stormed into the living room, her face marred with both streaks of flour and an angry expression. She was holding the empty ganache bowl aloft with exasperation in her eyes. Gabe looked up at her, trying to appear contrite, but finding that his eyes were focussing on a dollop of ganache on the edge of the bowl that he had somehow missed earlier. Lucy’s voice faded out as he stared at it, and suddenly it was her that he could hear, whispering in his ear.

“How did you miss that mouthful, sweetling?” she purred, and the merest hint of that dark, sultry voice caused his mouth to start watering. He swallowed deeply, trying and failing to listen to Lucy instead. Seeing her sweet face look so disappointed was hard but denying Belle once she had started working on him was so much harder. Even as he tried to ignore her, she began to manifest behind Lucy, her slender, almost sharp fingers slipping into that remaining ganache. She brought a small spot of it to her lips and licked it off slowly. Her brilliant white teeth nibbled her lower lip in apparent delight. Gabe groaned.

“What?” Lucy asked sharply, affronted. Clearly groaning was the wrong reaction to whatever she had said. “Jesus, Gabe, why are you acting like this?” Belle beamed wickedly at him over her shoulder. It was too much. With considerable effort he heaved his bloated body off the couch and waddled over to Lucy, taking the bowl from her hands and wrapping his arms around her. She stiffened for a moment and then relaxed, hugging him back.

“She won’t be able to get her arms around you soon,” Belle noted in playful tones. The thought made Gabe’s cock stiffen under his belly. Lucy snuggled further into him and he blinked, tearing himself away from the demon and looking down at his girl.

“I’m sorry,” he said sheepishly, and she sighed deeply, not responding. As she buried her face in the top of his fat gut, Belle crept closer to them, her black eyes glimmering wantonly. She pointed at the bowl that he was still holding behind Lucy’s back. His breath caught in his throat. “No”, he pleaded silently, his eyes wide, “no, not now, don’t make me…” but Belle always got her way in the end. There was no fighting this.

Hands trembling, he lifted the bowl to his mouth and licked up the last drop of ganache over Lucy’s shoulder. As she shrieked furiously and snapped out of the hug, he heard Belle giggling madly. Hell hath no fury, he thought stupidly.

Lucy left that night, to go to her mother’s house and cool off. With the place to himself, Gabe thought that he might have missed her enough to fight Belle’s attentions but it seemed that the opposite was true. He sat on the floor in front of the open fridge, back resting against the kitchen counter, his legs spread apart to give his gut room to expand. As the succubus emptied each shelf of the fridge into his mouth, he could feel it sinking closer and closer to the cold relief of the kitchen tiles, sagging down dramatically. Belle placed a cloven foot on his gut, treading firmly and forcing him to belch helplessly. Her eyes gleamed as she passed him a gallon of milk, watching huge rivulets of it spilling over his chest and stomach as he chugged messily. It was almost morning.

“Breakfast soon, my pet,” Belle said with a lascivious grin.

“The… *hic*... the fridge is empty,” he whimpered, and her grin widened considerably. “I - I can’t even move.”

Her gaze had settled on his phone, her smile smug and incontrovertible. With a low moan, he picked it up with fat fingers and began to order delivery. He was dreading the scene when Lucy eventually found him, but he couldn’t stop just yet. Belphegor had consumed him, and he too would consume everything in sight.
