Anyway, yeah, the clue is in the title. Oh, and be warned. This WILL get gory :}

Hope you enjoy.

I/VII/I/VII/I/VII/I/VII

He walked slowly through the dimly lit corridors. The pale moonlight shone through the tall windows, casting sinister shadows across his face.
His mission in Twilight Town had been a complete disaster; he had very nearly not made it out alive. To add to that, he had also failed to acquire the object he had been sent for.

But it wasn't his failure and near destruction that was worrying him. That wasn't what was draining him, emotionally and physically, sapping his energy.
"Stop it!" He chided himself. "We are nobodies! We. Do not. Feel!" He growled, the sound echoing through the empty corridor, sounding as though someone else had made the sound. He was almost tempted to turn and check.

"You cannot feel sad, or hurt."

Sighing, he stopped when he reached his destination, the usually comforting 'VII' reflecting the moonlight. He pushed the door open and stepped into the room.
It was rather under furnished, a small bed and window, a simple desk and chair and a reasonably sized wardrobe. All were white as were the bare walls, forming a box, representing the safety of the room. It was his sanctuary, the one place he was safe from everything beyond the door.

Sighing to himself again, he shook off the boots and collapsed, face down onto the low bed, his soft, blue hair falling over his face, hiding him from sight.

There was a small knock on his door.
It opened to reveal a pale, gaunt face, intelligent, green eyes and long, straight, blonde hair. Vexen.

"Number VII?" Noticing the berserker sat at the desk, he delivered his message. "The Superior wishes to speak to you in his office, immediately."

Saix nodded and approached the door. He shouldered his way past the scientist and started up the hall.
Vexen made a small, indignant noise but thought better of arguing with the berserker. Instead he just turned and hurried back to his lab, muttering about young people and their rudeness.

Saix however, was more leisurely with his pace. He knew what was coming. It was the same thing every other night.

He sighed again when he reached the large, white panelled doors. There was something about that 'I' that seemed so uncaring, so cold.

Ignoring these thoughts, he reached up and tapped lightly on the door. His knock was answered almost immediately by a bass voice, beckoning him into the room. He pushed the door open and stepped inside.
The room definitely did not reflect its occupant. The carpet was soft and gentle, the bed was snug and inviting and the fireplace, with its dancing flames. Nothing about the Superior could be called warm.
Only the desk represented the Superior, cold, emotionless and strictly business.

Before these thoughts could take him out of the room, Saix felt strong arms snaking their way around his waist, a strong chest pressing against his back.

"Superior."

The strong arms spun him and he found himself staring into deep, burning amber gems. The eyes of Xemnas, the Superior.

"Evening Saix. I'm pleased you got my message." His deep, bass voice vibrated straight through Saix. "I missed you."

Saix said nothing, he knew it wasn't true. Xemnas himself was always reminding the nobodies of their inability to feel.

Xemnas noticed the tense aura surrounding his subordinate. "Something wrong Saix?"

Saix lowered his gaze from the eyes that were trying to pry their way into his mind. "No Superior."

"Good." Good? Was that it? Just good?

Xemnas lifted Saix's chin with his hand, forcing the diviner to look into his eyes once again.
He leant down and placed a small kiss on the diviner's lips. As his superior's arms wrapped themselves around him in a tighter embrace, Saix felt himself melt into Xemnas' kiss.

They broke apart, breathless. Xemnas' lips ghosted over Saix's cheek, causing the berserker to gasp when he began caressing the soft, pale skin of his neck. His warm breath sent shivers down the diviner's spine.

Xemnas fiddled with the zipper on Saix's coat with one hand before he swiftly unzipped it, exposing the smooth, pale skin of the diviner's chest.
He then unfastened his own coat, shrugging the heavy black material from his shoulders. The bronze skin of his strong, chiselled physique gleamed.
Xemnas smirked and pulled Saix closer, feeling the smaller nobody shiver as their half naked bodies pressed together.

Saix felt a hand on the back of his neck before he was pulled into a fiery kiss. He wouldn't go as far as to call it passionate. If they couldn't feel, how could they know passion?

Xemnas pushed Saix backwards onto the bed, falling on top of him without bothering to break the kiss. He pushed himself to his knees, straddling Saix and finally relinquishing his hold on the berserker's lips.
He grinned predatorily.

Saix just lay under the Superior, watching the familiar hunger dance in his amber eyes. A hunger that would soon be sated.

Trailing small kisses down the chest of the diviner, Xemnas reached for the buckle of the diviner's tight leather trousers. The last thing obstructing him from his goal.

I/VII/I/VII/I/VII/I/VII End Flashback

Every time it was the same feeling. The hurt. The pain of being used. The realisation that he was merely a tool.

Surely having no heart should free them from heartbreak.

A single tear slid down his cheek. The Luna Diviner wiped it away and knocked.

"Back again Saix?" The smirk on Xemnas' face was one of pure victory.

Why do I always return? Why do I submit to him?

The thoughts were wiped from his mind as strong arms enveloped him.
