Lord Voldemort had never gotten aroused before, not even with Bellatrix Lestrange constantly making moves on him and sending him flirty looks every now and then. The only times he felt himself get aroused was when he saw a Unicorn.
Voldemort's feet brushed the grass beneath him as he ventured through a forest, feeling particularly sexual at the present time. He needed to find a Unicorn, and he needed to find one fast. He searched through the large forest for about half an hour before he finally saw a glimmer of pearly white fur in front of him.
It was a Unicorn.
Voldemort smirked and moved one foot, and at the movement the Unicorn started to dash away.
"Petrificus Totalus!" Voldemort cried out in his cold, high pitched voice. The Unicorn had a stunned look on it's face and it's body fell to the ground with a soft thump. Voldemort stared down at it's face of pure innocence.
"I'm going to have fun with you," he whispered dangerously, stripping off his Wizard robes to reveal a completely naked body. He levitated the Unicorn's body off of the ground and positioned it in front of his hard, pale cock.
"Erecto!" Voldemort joked, giving a laugh filled with no sympathy for the poor animal. He slammed his cock into the animal's hole, hearing a muffled shriek due to the Unicorn's body in a full body-bind. He thrusted harder and harder, pulling at the Unicorn's silvery tail. He could feel himself already feeling the need to cum, but perhaps that was because this was his first time.
He released his load into the now not-so-pure creature and he fell back, his dick slipping out of the Unicorn's ass and it's body falling to the ground in front of him. After a few minutes, Voldemort flipped over the Unicorn and saw blood dripping out of it's hole. Very much unlike human blood, the Unicorn's blood was a thick, silvery substance that was basically like cum, except it glittered in the moonlight and was most definitely not the same color.
Voldemort saw that the Unicorn was coming out of the full body-bind, so he robed himself once more and picked up his wand, walking out of the forest, feeling relieved and triumphant.
