Shizuo, he had no idea how, managed to catch Izaya. They were standing on the roof, Izayas' back being pushed against the fence. Said boy did not show a mere sign of fear, only stared at his enemy with his usual smirk. Shizuo was panting with his hand on Izaya's neck.

"Congratulations, Shizu-chan! You got me, have any further plans?" Shizuo growled because of the mocking tone. He studied Izaya from head to toe. Comparing to a normal 16 years old, the flea was too thin and there were black circles under his eyes as well. He leaned closer to have a better look, but as soon as that familiar scent reached him, his pants immediately became tighter. "Ara? It looks like Shizu-chan has a little problem~"

"Shut the fuck up or I will smash your head into this fence!" He wanted his voice to sound warning, but in his state, it was easier said than done.

"Have Shizu-chan ever made love?" Shizuos' eyes widened, because of the sudden question, then he sent a questioning look to the other. "Of course I have and believe me, I had good reasons."

Shizuo's eyes narrowed and distaste appeared on his face. He snarled at the other.

"Tch, I bet they are just as twisted and disgusting as you are," he said without thinking about the consequences.

In the next moment, he found himself on his back, with Izaya hovering over him. His knife was pressed against his neck and as Izaya added pressure, a sharp pain filled Shizuo's senses. The other teen looked at him with a look which promised death.

"Don't you dare to call my reasons disgusting ever again!" He warned the other, then stood up and walked back into the school.

Shizuo was walking by Shinra's side with a bandage around his neck. He really hoped that his family would not be freaked out because of it, however, they had seen him in bandages too many times.

They passed a sweet shop, when he spotted out a too familiar figure. He felt anger bubbling up from his chest and was ready to pick up a vending machine, when he heard the little chirp.

"Thank you for the sweet, Izay-nii!" A little girl said, smiling up at Izaya with affection in her eyes. Izaya only ruffled her hair as an answer.

"Nii-san goes away again?" Another little girl asked, stepping out behind Izaya with a sad expression on her face. Shizuo saw how Izayas' body became tense, then he knelt down before them.

"You have to promise me that you will behave extra good until I get home, okay?" Shizuo had never heard such sadness in his voice. Suddenly, both of the girls reached their lollipops to him, which made his classmate giggle sadly.

"Those are Kururi and Mairu Orihara – his sisters," Shinra said to him as an answer of his unsaid question.

"Don't you dare to call my reasons disgusting ever again!" Shizuo heard Izaya's sentence in his ears and he felt himself the biggest scum of the world.

It was lunch break on the next day and Shizuo searched for the flea. He wanted to say sorry for the thing he said, but first, he had to find him – which was not so hard because of that intoxicating scent of his.

"Come with me!" He said, grabbing Izaya's arm, pulling him up from his sitting position from beside Kadota.

"Shizu-chan, what the hell?!" Izaya tried to protest, but his words fell on deaf ears.

Shizuo simply pulled him after himself until they reached the roof. There he turned Izaya around, so they were face-to-face. Izaya gave him a suspicious look. Shizuo averted his gaze for a second, but looked back at Izaya eventually.

"I-I just want to say sorry because of yesterday…" He started, feeling embarrassed. "Please, tell me how can I make it up to you?" Because of the rather sadistic grin which appeared on Izaya's face a shiver ran down on his spine. Izaya pushed him against the wall, then his beloved blade was being pushed to his neck again. "Put that fucking knife away, damn it!"

"Now-now, Shizu-chan! You want to make your behavior up to me, right?" Izaya asked, leaning so close that he knew Shizuo had to breathe his scent in. As their hips being rubbed against each other, he heard a half-loud moan. Izaya's hands wondered to his jeans, unbuttoning it.

"Izaya, what are y-" but Shizuo could not finish the question, because of the strong squeeze around his manhood. He threw his head back following by a loud moan. Izaya pulled his boxers down as well, so he could touch the hot flesh. Shizuo tried to thrust into the hand around him, but the warning pressure against his neck stopped him.

"So impatient, Shizu-chan," Izaya said on a sing-sang voice. His smirk only grown as he was watching his enemy squirming because of his work on the most treasured part of his body. Izaya saw as Shizuo closed his eyes and heard his breathing became unsteady.

"Izaya, I think I will-" Shizuo started, feeling a knot forming in his stomach. Suddenly, he felt as the hand let go his member and the knife disappearing from his neck as well. "Why?" He asked, but it turned out as a half whine/half whimper.

Izaya's cruel laugher tore his heart into pieces. The other stepped in front of him, then whispered into his ear.

"Did you really believe that I would let you come?" The venom in his voice was only salt into the fresh wound. "I would never let any part of my body having that kind of contact with a monster like you."
