Demon euphoria go brrr
"What was it like? When you ignited?" the human woman asks, laying across her hellhound girlfriend's lap. "What, you think I wasn't born a hound?" responds the beast, fur of sun and flame of moon. "It's just a coincidence that you look like your favorite Pokémon generation?"
The hound huffs and turns away, just in case her blush decides to manifest above her fur. She can feel her mortal lover staring at her though, so she sighs. "It was... everything I'd ever wanted. I felt my consciousness expand, my soul burn so much my body couldn't hold it."
"I felt that cursed shell burn itself down to cinders and those cinders become a new set of biomass to be molded as I wished."
"So that's why you're so hung."
"You say that like my bulge wasn't what attracted you in the first place." she huffs, the human blushing this time.
After a moment of enjoying her minor victory, the hound continues. "And then I just felt free. I ran faster than anything on my old world could ever hope to achieve, I lept so far that I landed here and met you. I even went back in time and made sure your parents would be okay with us dating."
The human tilts her head. "What do you mean? They've always been so accepting my entire... wait... babe you can time travel!?" she shrieked.
"Like it's hard?" the hound responded, rubbing her sensitive ears. "You didn't even shriek about the mind control."
The human lays there for a long while after this contemplating, while the Hound just sits content with her lover across her lap.
Eventually that long while ends, and the human speaks up again. "I want you to bite me or set me on fire or whatever you do to Ignite someone."
The hound raises a brow. "I thought you were happy being a human? Just last night you went on a whole speech about how limited mortal lives are is what makes them mean something, like an anime character."
The human hides her blushing face in her lover's furry belly.
"Just shut up and make me a demon! I wanna be like you... I wanna be free and do whatever I want!"
The hound smiles softly, and pomfs her massive paw on the head of her lover. Moon colored flame shoots down her arm and wraps around the human, infiltrates every pore.
She doesn't even have time to scream before her lungs burn away, before her heart is nothing more than a smoldering hole. The woman that was once there nothing more than a pile of ash staining the fur of her lover.
Then that ash starts to vibrate. Softly at first, then violently In a single second stretched out to an eternity, a new Hellhound is born, bursting free from the ashes of her old life. Fur of sapphire and Flame of ruby, her eyes open to reveal pupils shaped like the symbols for alpha and omega.
The first hellhound snorts. "Copycat." The other snorts back. "Nope. Hound! Now come run with me." the newborn laughs out, before hopping up and down on her new paws and vanishing in a blur of motion, crashing through the nearest wall and out into the wilderness beyond.
The first smiles. "I knew I loved you for a reason." she says into empty air, before joining her lover in her first ritual zoomies. Twin trails of flame visible from orbit, racing across the surface of the world before leaping with all their might and becoming a shooting star.
