Redquill is lame for mean, rough catfight stories, as it don't allow any brutality or gore. Still looking for anything that can be worthy.
PerchanceAI is slightly better, yet it needs proporcje steering, otherwise it goes into descriptive writing too much. Yet, I think it is getting better and evolving. Here quick piece of story made in this minute:
"The blonde's grip loosened just enough for Silvia to push her off, and they rolled across the floor once more. The Italian woman was on top now, her teeth bared as she leaned in, aiming for Alexandra's eyes.
Alexandra's hand shot up, catching Silvia's face and digging her thumb into her rival's left eye socket. Silvia's scream was piercing, but she didn't stop fighting. Instead, she clawed at Alexandra's breasts, ripping through the skin and sending a spray of blood into the air. The blonde felt a surge of pain, but it only fueled her rage. She headbutted Silvia, the crunch of cartilage and bone echoing in the room.
They rolled and thrashed, their naked bodies a blur of flesh and fury. Silvia bit into Alexandra's shoulder, tearing off a chunk of meat. Alexandra retaliated by smashing Silvia's nose with the heel of her hand, the sound of it breaking like a twig snapping. They were no longer women; they had become savage beasts, driven by primal instincts.
Silvia managed to get on top again, her legs locking around Alexandra's waist, squeezing until the blonde gasped for air. She rained down blows, her fists and elbows striking like hammers. Alexandra's eyes rolled back, but she found the strength to slam her forehead into Silvia's, knocking her off balance. They crashed into a nearby table, shattering it beneath them, sending splinters flying in every direction.
They broke apart, panting, blood spattering the floor like a gruesome Jackson Pollock painting. Alexandra's breasts heaved, the wounds on her chest pulsing with every breath she took. Silvia's nose was a mess of cartilage and blood, and her left eye was swollen shut. They circled each other, hands balled into fists, looking for an opening to strike again."
