"Oh Lord Lucifer, now that I gathered the volunteers we can begin my ascension" Alice said looking up with her arms extended and eyes closed.
"Ascension?" Mei said quietly looking confused at Ty.
Ty and Mei tried to move but instantly a group of shiny purple tentacles grew from the floor and wrapped around their bodies, watching how Alice moved freely while many tentacles were around her. Alice walked to the center of the circle and drank the bowl with the fluids of everyone leaving it empty, Alice cleaned her mouth with her tongue and smiled showing a perverted but scary face.
"Alice! What are yo doi-" Ty tried to say but a tentacle got into her mouth, the same with Mei.
"Is the new form Lord Lucifer will give me, he will get rid of my ugly human form and turn me into a beautiful creature after years of proving my respect and loyalty to him, I'll be able to gather souls for him and help him to come to this world! And you... Will be the fuel of my change!" Alice laughed.
The tentacles that trapped Mei and Ty moved to Alice exposing her naked body with her arms and legs extended, then the tentacle holding Ty slowly approached to Alice's crotch, starting to fuse him with her pussy, he tried to scream but the tentacle already was inside his throat, in less than a minute Ty was fully absorbed by Alice's body. The tentacles now moved Mei to Alice's chest as she cried sucking a tentacle, then she disappeared in the middle of Alice's tits.
After that Alice felt an incredible power through all of herself, being sorrounded by a red aura. Her body grew and changed into a more mature form, looking like a chubby 40 years old milf with her tits turning into E cups, a round sexy ass and her face aged matching with the appearance of her body, then her skin turned red as black horns grew in the top of her head, her tongue and eyes turned black with red pupils and her hair colored white. For the final changes her feet merged her fingers turning into hooves, covering all her legs with black horse hair, suddenly her vagina shaped into a human face with its mouth opened, that resulted being Ty's face which grew a horsecock from his mouth, he could feel and see anything but could do nothing, just feeling how Alice's monstrous body changed. Then another pair of arms appeared below their existing ones, her nails stretched into big black claws as a spiky demon tail grew above her ass and a pair of bat wings appeared in her back. Alice smiled looking at her chest knowing her final change, another boob appeared between her original two, but this one had eyes on top of its nipple, being Mei's eyes, sharing the same fate of Ty as she was unable to move but feel and see everything.
Now that Alice's transformation was complete she received a message from Lucifer, "Alice, my daughter, you have acquired the wonderful appearance that I offered you, now it is your duty as the lust demon to gather more souls to make possible my appearance in the human world, as you take more souls I'll give you more changes in your body that will grant you many abilities and powers. Do not disappoint me".
Alice excitedly accepted their mission stopping her talk with Lucifer, before she started her new job she gave herself a little time of pleasure squeezing Mei's nipple and masturbating Ty's cock mouth.
