She embrace her demon side

The water bubble and produce vapor until it explode in a huge geyser of hot water that cool down as it falls. In the emptied fountain, Lilly stands in her now demon form, her skin turned white-blueish with her hands and feet red, her nails had grew long and pointy like her ears. Two horns two half-a-feet high white horns ornate her head above now deep red hairs, her crimson eyes are glowing and enhanced by dark make up, and finally a pair of small red bat-like wings have sprouted from her back.

The demoness took a deep breath and walked out of the fountain. She spotted a group of girls that was watching the whole thing like it was a show and pointed at one of them.

"You there ! I want your face between my legs. Now !" She ordered.

The girl, in goth clothes, walked to her and with each of her steps, the clothing and make up of the girl became more and more slutty.

When she finally reached to Lilly, she went on her knees and started to lick her pussy.

"OooOh, yes, that's a good little slut !"

Her friends were in shock and asking her what she was doing, that it wasn't like her. But Lilly made a move of the hand, showing them to leave them alone.

"That whore is mine now, you'll get her back if I feel like it."

And with that, the girls leave to go further into the park.

Lilly turned to Asmodeus, smiling.

"It's so good to feel so much power over mortals... dad..." She said, pushing the goth girl face even more against her crotch.

"I'm happy, you finally embraced your inner self, daughter, but be careful to not over do. On this plane, your powers have limits... for now."
