The young, ambitious titan-shifter sat unsteadily in his chair as he gazed longingly at a petite Corporal, seated on the other end. He shakily bit at his nails until the very skin underneath bled. As the small talk with the squad went about, the shifter's eyes grew dark and he never lost his look on the Corporal. Each moment his oceanic eyes spent gazing at the man, only drove his thoughts to become more twisted.

A throbbing occurred in the back of his head which finally caused him to break the gaze. The boy closed his eyes briefly and reached a hand to his head in attempted to sooth the discomfort. Strangely enough, this has been happening frequently to him. The instant he took the time to gaze upon Rivaille, that familiar pain in his head seethed. The pain and the overwhelming thoughts of vulgarity.

Now as he stood, his finger tips bleeding and head throbbing, Eren made his way toward the Corporal. As he approached with his hands behind his back and out of sight. He knew anyone seeing him wounded would immediately jump to the worst conclusions.

Rivaille glanced up at Eren with an unamused look and quirked a brow. Eren gulped to himself now as he locked their gazes together. At that the throbbing in his head escalated along with his desires.

"P-Pardon me sir..." The boy cleared his throat before continuing. "May I please be excused for a moment to use the restroom?"

Rivaille gave an annoyed "tch", then simply waved the boy off out of his presence. The boy furrowed his brows slightly at the Corporal's blunt actions and walked out of the mess hall area. He hadn't needed to use the restroom, no, he just simply needed the relief of being away from the Corporal.

Only recently had the boy's gruesome desires with the Corporal grown. Over time they'd escalated now to physical agony. They were driving him insane, day by day. Now he'd often force himself away into the cold dungeon in which he was shunned to.

There he could fantasize about his desires, often those fantasies would grow so intense that evidence of them was prominent. For instance in a fit of ecstasy and more than anything, sexual needs when it came to thinking about Rivaille. The shifter would desperately attempt to please himself, leaving the sheets of the cot soiled and stained. On occasions he couldn't refrain from doing it to himself more, and he would settle to fantasize in pleasuring himself more than once.

Seeing the mess he made only made his frustrations grow more. After every round of erotic actions the boy would wipe the sweat from his forehead and tremble at the thoughts he still had. He would look at the semen on his sheets and feel please yet revolted with himself. Eventually, he was resulted with an outburst. He tore the sheets and slammed his fists into the wood of the cot. Growled and snarled like an angry animal, all while raking his nails into the wood or walls around him.

These things he'd done, the way he pleasures himself through the hallucinating fantasies. They were all directed toward the Corporal, each and every time he'd done it. Every time the boy does this to himself he remembers the reason. Corporal Levi, always the reason. The boy realized himself the tantalizing, sexually vulgar obsession he had for Rivaille. After coming to terms with it, his erotic actions grew more and more everyday he'd done them.

That's just what he knew when he'd snuck the thick rope from the stables down to his dungeon room for a little "fun". As he tied the rope and bonded it, often times even to himself, he thought about the Corporal. He thought of roughly tying the shorter male up and binding him to the bed. He thought of making every inch, centimeter, hair of that man's body his, and never letting anyone else near. He wanted to take the Corporal away and lock him up forever, so Rivaille was only ever within Eren's reach.

Now as the boy was enveloped in his routine of ecstasy, he was positive of what he wanted and how he would get it. In the midst of pleasuring himself, Eren pulled his hand away from his throbbing member and sat up panting. His eyes were dark and unkind as he smirked devilishly to himself, knowing what was to happen next was going to be reining end to his fantasies and beginning of a pleasing reality. He knew he would have Levi all to himself.

Eren reached his soiled hand up to his mouth and licked it clean, all while still wearing an evil grin. He slipped his clothing back on then made his way back up the staircase. With only one thing on his mind he entered the mess hall again. He saw the Corporal out of his seat and approaching the door Eren had just entered through.

"Lucky you returned Jaeger, I was about to come looking for you." The short man stated bluntly.

Lucky for you, you didn't.

Eren grinned inwardly but kept neutral on the outside as he replied. "I apologize sir, I won't take so long next time."

Rivaille furrowed his brows. "Must of been one hell of a shit you needed to take."

Eren simply ignored Levi's awful toilet humor and glanced around the room. The other squad members were nowhere in sight.

He was all alone in the mess hall, with the Corporal.

Perfect.
