Age of the Succubus

The large doors to the throne room swung open with a heavy impact, the sounds and smells of sex flooding through. Lucifer glared from his obsidian throne at the woman who entered uninvited. Lucifer couldn't deny that the woman was gorgeous, and of course she was, she was Lilith L'Amore after all, the most powerful succubus of the known world. She had a perfect hourglass figure that was perfectly accentuated by her black leather lingerie. Her long, straight, white hair reached just above her ass and her shimmering purple, heart shaped eyes pierced into her opponent.

Lucifer knew exactly what the succubus was there for. The two of them had been at war for the last decade, and today was the day that one of them would face their demise. Lucifer grinned sadistically as he shot his first spell. This spell was a spell of his making that he liked to call overkill. A spell that never failed to kill his opponents in a single hit.

The massive ball of blood red magical mana flew towards Lilith but all she did was smirk and blow a kiss towards it, and a pink heart shaped cloud flew from her lips and hit the red mana sphere. The red mana instantly turned into a pink cloud and hit Lilith harmlessly before dissipating.

A look of sheer horror struck the Demon King's face. That spell had never failed to demolish every opponent he cast it on, no matter if they tried to dodge or block it always hit and always killed. "What did you do!!??" Lucifer shouted in anger. "How did you block my attack!?"

Lilith just laughed in response before blowing another kiss, this time filling the throne room with a thick pink fog. Lucifer tried to hold his breath but he instantly felt that it hadn't worked and the fog somehow seeped in through his skin. He felt a pleasant tingling sensation on every inch of his body as he became somewhat lightheaded. He fell from his throne in a daze, his clothes had somehow disappeared and his cock was achingly erect between his legs.

Lucifer looked up and all he could see was Lilith standing above him, everything else was shrouded with the pink fog. The succubus had a sexy, sadistic smile on her face as she looked down at the easily defeated devil. She stepped over his head giving him a clear view of the slit in the fabric between her legs and she began to squat until she was firmly seated on his face.

Lucifer was achingly hard and horny and couldn't resist lapping at the dominatrix' soaked slit. The taste was divine, unlike anything the Demon King had ever tasted in his centuries of life. He enthusiastically lapped at the woman's slit, relishing in the taste and failing to notice the changes occurring to his body and mind. He began to feel a new... no, a familiar weight on his chest. The pressure between his legs began to come inward and he could feel a new wetness gathering where his testicles had been. 'Testicles?' she thought. 'I've never had testicles.'

Why had she been referring to herself as a male earlier? She had always been her mother's daughter and had always had the same beautiful white hair. Who was Lucifer? Her name is Lucy and it always has been. She continued lapping up at her mother's pussy until Lilith pulled away. "That's enough," Lilith said, smiling down at her new daughter and patting her on the head. "Good girl, Lucy."

Lucy beamed up at her mother. "Thank you mother!" She said enthusiastically. "That was delicious!"

The inside of the throne room began to change along with Lucy. Cracks began patching themselves, and the old banners were replaced with new ones that had a heart shaped symbol on them. Things even changed outside of the throne room, and soon the entire demon kingdom had a new refurbished look. The monsters and demons began to change as well. They had all been hideous and bloodthirsty beasts before, but they began to change into something new. Every monster becoming more feminine and having new reproductive tools along with their minds changing from hating humans to absolutely loving them and constantly craving sex with them.

These effects even passed outside of the kingdom, affecting even the land itself, demonic plants changing into something new, and even pools of water gaining a new pink hue to them. The effects on monsters continuing to spread even outside of the demon realm, and into every realm in the known universe. In a single night, every demonic thing or being in the known universe went from hideous and bloodthirsty to sexy and cumthirsty.

A/N: Hello there! I have set this story to public and I strongly encourage you all to write your own branches and create something beautiful. Also if you don't know what the monster girl encyclopedia is I strongly encourage you to check it out. Here is the MGE wiki.

I will only be using MGE monsters in my branches and I will try to keep them as accurate to the MGE as possible unless they are canonically lolicon monsters in which case I will change them to follow site rules. You as writers do not have to stick to the MGE monsters tho and you can write about any other monster girls/boys that you can think of as long as you follow the site rules.

Also, if you don't want to write a branch yourself, feel free to leave a comment with what you wish to see, and it may be added by another writer in the future.
