Trick her.

Aaralon's senses returned to him, she had focused on his shadow for long enough that the pleasure that was clouding his mind could fade.

Aaralon knew that demons could never be trusted, and he was certain she wouldn't just leave him alone if he refused.

Aaralon looked down at her swollen pussy, dark energy in liquid form oozed out of it and it's smell was a alluring.

Aaralon focused his thoughts and wordlessly enchanted his cock. Coming into her would release a paralyzing toxin instead of his cum, this is how Aaralon would gain the upper hand.

Aaralon kissed Amalirel heavily, he stared into her eyes and thrusted his throbbing cock in her.

She smiled and pushed him down, he landed on his back.

"You made the right choice," she smiled.

Amalirel had full conscious control of her vaginal muscles, she focused all of her thought on them, suffocating his cock, she thrusted down onto him, her large breasts bounced with each thrust. She thrusted in perfect rhythm, slamming herself down on every beat.

Aaralon moaned, "I'm coming Amalirel!"

Amalirel heaved and moaned, "I...am...too," she stared at him with her piercing indefinite eyes.

Amalirel came. Her body writhed and twisted, all of her muscles tightened freezing her in place. Aaralon stared at her beauty as his cum came bursting out of his cock. Green chunky goo filled deep inside of Amalirel's demonic body. Aaralon shot rope after rope of the toxic sludge. Amalirel didn't notice and she moaned in bliss as she felt herself filled by Aaralon.

"Vexis veronis!" Amalirel shouted.

Aaralon still sat under her with his human form in tact.

"What the... Vexis vernois!" she shouted again.

"The hell?! VEX--" Amalirel was cut off as her muscles froze.

Aaralon crawled out from under her rock solid form and admired her beauty for a moment.

"I guess the puny mortal has more potential than you thought," Aaralon cackled.

"I got my cake and ate it too," Aaralon laughed and cleaned himself up.

"Hmm Amalirel, I have no idea who you are and why you chose to bother me, but I'm afraid I'm going to have to find a way to punish you for breaking my amulet,"

Aaralon placed his hand on Amalirel's forehead and dark energy radiated from Aaralon's hand.

"Terror dra ca-do!"

Amalirel's form vanished and in its place was a small gem. Aaralon placed the gem inside a jewel encrusted locket.

"I wish you luck, Amalirel," Aaralon laughed at the necklace "Whoever wears this will be possessed by you. Except you will have no memory of anything and you will retain nothing, not even a drop of your demonic powers, you will be a mortal forever,"

Aaralon spat on the necklace and carefully placed it on an end post in the girl's dormitory wing of the junior academy. Surely some brainless boob would put it on.

Aaralon returned to his study with a smile engraved on his face.
