Will and Cassie were out after a demon. A Ruguru, in fact. Not much was known about them so John stayed behind with Sebastian to research. Though he did enjoy research, John had an ulterior motive for staying behind. He had noticed that Sebastian seemed different. Sebastian used to be a stickler for rules and procedures; but lately, he seemed to be breaking every rule there was.

"No one changes that drastically without a good reason," John muttered to himself, pacing back and forth in the library.

"What's got your knickers in a twist?"

John twitched but didn't stop pacing. Truth be told, he was vexed with himself because he didn't notice that Sebastian had entered the room. This also pointed towards the fact that something about Sebastian was off. John could hear the slightest sound. Heck, he could hear the mice scrabbling in the attic, three floors above. Yet, there was no sound when Sebastian moved.

John finally stopped pacing and looked at Sebastian. He was wearing black Vans, black cargo pants, and a white wife beater that molded perfectly to his chest and back. A green and silver snake tattoo encircled his upper left arm. His hair was short but long enough to be gelled into spikes. They were black with red tips. Then there were his eyes. They were a brown the color of dark chocolate.

Looking into his eyes, John steeled himself for a confrontation. "Sebastian," he said, "we need to talk."

Sebastian smiled wolfishly and his eyes flashed black. "Yes we do," he agreed, right before his fist connected with John's face, knocking him out cold.

Now

Cassie broke away from John's fingers with a gasp. "Bloody Hell John! The Bloody bastard Bloody sucker punched you!"

The corner of John's mouth twitched but he refused to smile at his sisters vehement swearing.

Eyes flashing, Cassie turned to her brother. "Why didn't you tell me?" she demanded.

John sighed. "I didn't tell you because you would have cut the Cad's balls off."

"Damn straight I would," Cassie agreed.

John shook his head. "Just hush," he told her, "I have more to show you." John put his fingers on Cassie's temples and once again drew her into the memory.

When John came around, he had a splitting headache. Not only that, but his arms, not to mention his wrists, hurt a lot. He tried to move his arms so he could massage his wrists, but found he was restrained. He tried to move his arms around so he could slip them from the bindings, but stilled when Sebastian's low chuckle echoed around him.

"Don't bother trying to escape," Sebastian told him, "the more you struggle, the tighter the ropes get."

John slumped in the chair and blew his bangs up. "Why are you doing this Sebastian?" he asked in a serious voice.

Sebastian walked around John until he was in front of him and leaning against a table five feet away. "It's always the same questions," Sebastian said, amused. "Who are you? Why are you doing this? What did I do to deserve this?" Suddenly Sebastian grinned, all teeth and very threatening. "Can't I just do this because I enjoy it?"

John looked closely at Sebastian but even so, he almost missed the yellow flash in Sebastian's eyes. That flash caused John to straighten in his seat and become extremely cautious. He was no longer dealing with Sebastian the asshole; he was dealing with Sebastian the demon possessed asshole.

Answering Sebastian's question, John spoke. "You may enjoy this, but that's no why you're really doing this."

Sebastian cocked his head in amusement. "Oh really. Well then, tell me why I'm doing this."

John's anger grew at the smug look on Sebastian's face, but he kept his outward appearance calm, knowing that anger wouldn't help. So he smirked and spoke. "You're doing this because you see me as a threat."

Sebastian lifted an eyebrow. "And why is that?"

"Because," John told him while working at loosening the bindings on his hands, "I'm a demon hunter and you're a demon. CHRISTOS!!!!"

The demon masquerading as Sebastian laughed. He was slowly morphing into his true form. He grew taller, his eyes growing closer, his brow growing out. His lower jaw extended and grew tusks that curled beyond his upper lips. His shoulders grew broader, his arms longer, his legs shorter. His body bulged obscenely with muscle. In this form, the demon communicated in a series of grunts and squeals. Luckily John was up to date on his 'Pig-Latin' (pun intended) and could understand what it said.

"You are a threat," the demon agreed, "but not because you're a demon hunter but because you're the brother of the female I will mate with."

This comment broke John's calm and allowed him to break the bonds on his hands. Wisely, he kept his seat, bidding his time while waiting for the perfect opportunity to attack.

But he couldn't stop his mouth. "You won't touch Cassie."

The demon laughed. "I'll do more than that. I'll wrap that red hair around my hands and pound her so hard she'll beg for me to fuck her every night. I'll shove my huge cock down her throat so far the only thing she'll be able to swallow is my cum."

The demon was getting excited by what he was saying and his two foot long cock was rising to attention. When it was fully erect, John struck. Pulling a silver knife from his boot, he quickly closed the distance between himself and the demon and with a single downward stroke, cut off his dick.

"Kind of hard to fuck with no cock," John told the demon right before he slit its throat.

Now

"Fucking bloody hell!" Cassie yelled as she pulled back, breaking the connection. "If I had known that was what Sebastian really looked like, I would have never messed around with him."

John chuckled a little at her reaction. When he spoke though, he was serious. "Now do you get why I'm so upset?"

Cassie nodded, and then pulled her brother into a hug over the center console. "I'm sorry Johnny; I had no idea that he wasn't Sebastian anymore."

John pat his sister's back. "It's all right Cassie, just be more careful from now on."

Cassie squeezed her brother before letting him go. "Don't worry Johnny, I will." Buckling herself in, Cassie started her car. "Look out Ipswich, Massachusetts, her we come!"
