You shouldn't disobey your senpai, Delic.
It's rude.
Especially when your senpai gives one a few simple rules.
One of those rules being you're not allowed to love anyone else.

"Senpai…what are you doing with Izaya's knife?" the deep baritone trembled slightly, his magenta orbs catching sight of matching magenta hues, only darkened slightly, crazed with rage.

The brunet flashed a terrifyingly sweet grin at his kouhai, gliding the knife along his blouse lightly. The blond gulped as the knife came just a bit too close to his neck. He quickly made a move to catch the smaller's wrist and snatch the knife but Psyche moved to fast, slashing at Delic's hand. He retracted the now bleeding appendage with wide eyes. So out of character for his sweet little senpai.

Psyche glared, his sugar sweet grin still lacing his lips yet the malice in his crazed eyes sent shivers down Delic's spine. The brunet crawled up, sliding the knife down the center of Delic's shirt, slicing away the buttons and pushing open the cool fabric with his long spidery digits. A smirk that should've been on the face of Izaya Orihara now laced the ever so innocent Psyche's features.

"What happened, Delic?"

The brunet put more pressure on the blade, slicing into his kouhai's skin. Delic groaned, unintentionally arching into the blade and making his new wound deeper. Yeah, nice going, Delic. Real smooth. Seemingly psychotic magenta orbs locked on a sane shade of magenta hues, widened with fear as the blade was brought back up his chest, a thin trail of blood following the steel as it raced up towards his neck.

Delic tried to keep still, lest he arch into the blade again and accidentally slice something important. "What do you mean, senpai~?" he kept his voice calm, smooth.

"You broke the rules."

I'm your's.
You're mine.
We don't share each other.
Sharing isn't allowed.
Those ars the rules!

Psyche brought the knife down again, slicing a trail down to Delic's pants. He felt the taller man tense up immediately and sliced away the belt. Delic squirmed, thoughts running wild. He couldn't be thinking of cutting…cutting it off right? That's crazy. Innocent little Psyche would never do such a thing…right?

The blond gulped and watched in horror as his senpai tugged at the zipper of his trouser with his teeth. Yanking the metal down, Psyche's eyes flickered up to briefly meet the horrified gaze of Delic. His lips curled up, his smirk seeming to become even more devious as long thin digits pulled his kouhai's cock from his boxers.

"Senpai…you'd better not do what I think you're about to do…"

"Oya~? And what do you think I'm about to do?"

Delic couldn't believe this was Psyche he was dealing with. Especially as the brunet gripped the length in one hand and wielded the knife in the other, holding it as if he were holding a pencil.

"This won't hurt a bit! Just make sure to stay reee~al still, or I might accidentally cut it off!"

Did he really just say that? And in such a cheerful tone too? Before Delic could even compose a reply he felt the blade dig into his sensitive skin. The blond arched and threw his head back, his mouth contorting into a silent scream. Desperately Delic tried to keep still, he didn't want to risk losing his manhood to someone as clumsy as Psyche. His breath came out in harsh pants, watching in horror as his senpai carved his name into his cock.

"S-senpai…"

Psyche seemed to ignore the stuttered cry. Instead flicking out his tongue to lick the blood away from the brand new wounds. He dropped the knife in favor of holding on to Delic's hips while lapping at the crimson liquid until it finally ceased it's flow.

Now everyone will know you're mine.
