Play a holy song

Liandra couldn’t just stand by and do nothing. She took her harp and quickly flipped through the pages of the book. She had seen a fitting melody somewhere. If only she could get it in time.
The devil laid Rodrick on the altar and spread her legs. Rodrick looked between her legs and could see his large red cock, hard and ready to enter her.
Luckily for Rodrick, Liandra had found the correct melody and started playing it.

The song was beautiful. It sounded heavenly and divine. When the devil heard it, he cringed in pain.
“What is the meaning of this?!” he yelled.
Liandra remained where she was and continued playing. She didn’t need to show herself, she just needed to play. This melody was a song of purification. It would severely weaken any demonic creature that heard it. If she could keep this up she could defeat this monster.

The devil cringed in pain. “Who is playing that song!” He screamed. “Show yourself!”
Rodrick saw the demon now kneeling on the ground. He needed all his strength to keep from falling flat on the ground.
Rodrick got up from the altar … and kicked the devil in the groin. The devil could no longer hold it and fell. Too much strength had been sapped from him. He was no longer able to stand.

Liandra finished the melody and the cave was filled with a heavenly light, keeping the demon subdued.
That was when Liandra came from her hiding place and entered the room.
“Liandra!” Rodrick called happily, unaware of the changes to his body that had taken place. It was only after she hugged the princes that she realized she was naked. She blushed and quickly tried to hide her private parts.
Liandra herself however was more interested in the devil, or at least, the potions he had on him.
“You will die for this, puny human.” The Devil told her. “Once I get my strength back, I will **** you until you beg me for ****.”
“Perhaps,” Liandra said while she pulled free one of the devils potions. “But perhaps maybe not.”
Liandra uncorked it and **** the devil to swallow it.
The devil managed to yell “No! Bitch!” However it was too late. He now went into a similar transformation as Rodrick had gone into previously.
His hips broadened, his breast formed tits, cock disappeared and gained a seductively female body.
“You won’t be **** me any more now that you’re a succubus.”

“Ufh, foolish little human.” The She-devil spoke. “You didn’t change my essence, merely my gender. You never decreased my status to that of a succubus, I am still a devil. Just a she-devil now.”
“Indeed you are,” Liandra said, slowly becoming aware of the bulge forming under her gown. “A very pretty she-devil.”
