Omlette :)

The man at the bar grunted in annoyance watching a group of young women enter, dressed to emphasize their feminine builds and just visibly having a good time. He sipped at his whiskey, struggling not to make a face at the taste nor at the drips traveling down his beard. He's not jealous or angry. He's a big, cool, strong man's man and he never stares at his rough hands or face and feels anything. Men don't feel things. They just go to work and get things done and grunt and growl in annoyance at things that aren't Men.

His fellow men join in this. Work buddies, internet friends that turned out to be nearby. They're great dudes, they can all be miserable together. For the gender of it all, y'know? Not that they would care about gender. That's for women. A certain smell reaches each of their noses as a hellhound seems to manifest out of thin air behind them, sniffing at the air and then locking eyes with each of them in turn. Her fur the color of estrogen and flame the color of pride. She grins, teeth glinting in the light.

"Hey there~ I couldn't help but notice you big strong men sitting here without any feminine company. Mind if I join you~?" she asks, already planting her plush ass in one of their laps and twirling her hair while grinning at him. The men exchange nervous glances. They saw a reddit thread about Hellhounds once and it said some weird things, but... well her tits are expanding in front of their eyes and she's rubbing her thighs together just smelling them. Men are supposed to fuck anything that moves, so...

They move to the seedy alley beside the bar, the hound giggling and stroking her paws over their bodies. "Just a needy lil' bitch, eh boys?" one laughs, and the others join in. They're so busy laughing they don't even notice the alley warping and twisting in space. Don't notice themselves stepping out of their world and into the hound's lair until she snaps her paws and chains burn themselves into existence around their wrists and ankles, hoisting them in the air, clothes evaporating into atoms exposing every inch of them to the Hound. She rubs her paws together and licks her lips. "I do so love making an omelet."

"Th' fuck do you mean!? Let us down, demon!" one of them roars in his most commanding voice, the one he uses to make every woman in the room uncomfortable so they leave him alone. The hound just laughs. "Please, ma'am. Calm down! This is all for your own good." with a snap of her paws the man that spoke up is dragged in front of her and bent over by the chains. The hound grips his hips and grins at the horrified other men before thrusting against him. Cock and balls collapse in on themselves as a vagina and a womb burn themselves into existence. Every thrust slaps heavily against an ass that is slowly growing rounder and softer, hips expanding to fill those paws. His screams of pain grow higher and higher pitched.

Breasts form at the same time the body hair explodes out into a silky soft layer of fur, color of acceptance, a wagging tail erupting out of the tailbone at the same time a muzzle forms. Her tongue lolls out of her muzzle as she's fucked, all thoughts of masculinity now a puddle. The Hound pulls out as she cums, covering the back of her newly formed sister. The cum sizzles on her back and becomes smoke that curls comfortably around the shoulders of the new hound, her "Flame" manifested. The chains release her and she lays panting and drooling on the floor

The next "man" is brought over in moments, sharing the same fate, now clad in fur the color of euphoria and surrounded by a pleasant drizzle of rain, flame taking the shape of storm clouds overhead. The next? Fur the color of bliss, "flame" the very ground beneath her paws bubbling around her, stretching like a cartoon to drape down her body like an absurd feather boa made of demonic concrete. The final egg is eager, begging to have her shell smashed so intensely that it's like it never even existed at all. The newborn hound has fur the color of space and her flame takes the shape of spectral clock hands ticking and tocking behind her.

The four newborn little sisters weep openly and loudly, hugging themselves and each other and then finally dogpiling on their new big sister, incoherently bubbling out thanks while also humping any part of her they can get to, squirting all over her fur. The big sister just laughs and pets each of their heads, and after a few hours of watching her new family members decide just HOW obscene they want their feminine proportions to be the pack moves out to another mortal world, another bar with a group of "men" drinking in silence.
