Soft hands roamed over a smooth chest, pulling a moan from a dark haired man as he threw his head back, his fingers grasping at the sheets underneath him. Lips moved to his neck, sucking softly as they drew another moan from the man, this time in the form of a name.

"Sa-Saga-sensei…"

The man chuckled against the sweet neck of the boy, pulling his head back to stare into the emerald eyes of the one underneath him.
"That's right Ritsu, say my name." He murmured softly, gently caressing the boy's cheek with his hand. Topaz eyes stared into emerald eyes as he leaned down and kissed the smaller man deeply for a moment, running his tongue along the other's lips as he pulled back.

The larger moved his head back down to the boy's neck, kissing softly as his hands moved to the boy's shoulders, pressing him down harder against the bed.

Ritsu moaned, tilting his head to the side to give the other better access. It just felt so good, so wrong, and yet so good.
Who would have ever thought that he would be doing something like this with his teacher?

It had only been a few weeks ago that he had accidentally confessed his love to his handsome yet standoffish teacher. He was shocked when instead of being refused immediately, the man simply looked his student up and down and accepted.
Their relationship started quickly and advanced at a pace that the student wasn't used to and had never experienced before.

The first week in they went on a date to a nice restaurant. The day had been cloudy but ended in pleasure.
The second week in the teacher had kept Ritsu after class and had proceeded to make a mess of him on his desk until it was dark.
The third week in he convinced the student to come home with him and stay the weekend. He had picked Ritsu up in the dead of night and didn't let him return him home until late on Sunday.
And now, here they were the fourth week in. They just finished watching a movie at the teacher's apartment, he had been pushed down on the bed only minutes ago and the teacher had almost immediately latched onto his neck.

Ritsu had to admit that the man really seemed to have a thing for his neck.

The brunette moved his hands up, running his fingers through the man's hair. The kissing slowly became sucking which then became gentle nips which then turned into harder nips, causing him to flinch and whimper softly.

"Se-Sensei… That kind of hurts.." He mumbled meekly, not wanting the man to pull back completely. He only wanted the biting to stop.

His teacher didn't seem to listen though as he continued to switch between gently kisses and rough bites. Finally Ritsu had begun to tug at the strands, wanting to pull him away from his neck.

"That really hurts… Sto-stop it."

He was pressed harder against the bed, fingers digging into his shoulders just like the teeth on his neck. He squirmed in the man's grip, growing uncomfortable by what was happening. He wasn't sure what to do in this kind of situation.

On one hand it felt good, there was pleasure rolling through his body like waves and he wasn't even sure where it was coming from. But on the other hand the pain in his neck was getting worse, the other's teeth were even beginning to feel sharper, it was like he was piercing him with each bite.

By the time he realized what had happened, it was too late.

Teeth were suddenly plunging into his neck like sharp hot needles, leaving him paralyzed out of shock. The pain was indescribable, his neck felt like it was fire, but then slowly it faded away, leaving a ball of pleasure in its wake.

Ritsu moaned loudly, fisting the man's hair as he arched up against the body.

He wasn't sure what was happening.
It felt so good.
And yet it felt so bad.
He felt like he was dying, every ounce of life leaving him.
He was excited.
He was terrified.

He was growing weaker, the moans had died down and he was left just gasping, breathing heavily as the world slowly began to turn dark. He couldn't seem to keep his eyes open for any longer, everything was slipping away from him slowly.

The last thing that he saw was the man above him, bright red liquid dripping from his mouth as dark topaz eyes stared into what seemed to be his soul.

A deep voice ran through his mind as everything finally faded around him.

"You're mine forever, Ritsu."

Green eyes shot open quickly, the man sat up hurriedly in his bed as one hand slapped against his neck and the other pressed against his chest.
He could feel his heart beating a mile a minute while his breathing came in heavy pants. He felt like someone was trying to suffocate him, his entire body seemed to have gone numb.

He had to force himself out of bed, stumbling to the bathroom where he stared intently into the mirror.
His hair was a mess, his eyes were large and dilated. His face was pale as a ghost and the world seemed to be spinning.
What felt like hours but was only seconds seemed to pass before he was able to slide his hand away from his neck, looking with wide eyes at the spot where he still felt burning teeth.
There was no blood. There was no open wound. There were no red marks. The only thing that he could see, the only thing had seen for the past ten years, were those two little light scars that were ever present on his light skin.

The voice still played over and over through his mind, sending chills through his spin and yet reawaking a deep longing that had be buried far down inside of him.

"You're mine forever, Ritsu."

I'm still not sure where I'm going with this, it's mostly a random idea that came to mind that I decided to roll with.
