a/n: Hullo guys. I hadn't realized how good this fic was doing until I wrote some Takao x Midorima that I'm actually really proud of, but no one reviewed it! ;_; well, if you like Kuroko no Basuke, the fic is on my page. ;)

disclaimer: I do not claim to own Durarara!

Shizuo wasn't sure when he came, and he wasn't sure how that had transitioned into Izaya on top of him, moaning and bouncing on Shizuo, whispering his name over and over again while wrapping his arms around the blonde, but he knew that he was completely ensnared by him. Ensnared by his sensuality, his passion, but somehow there was still something holding Izaya back. It drove Shizuo crazy, and he was unable to put his finger on what exactly was bothering him.

Shizuo also guessed that he should've been bothered by the fact that Izaya was practically a stranger, a not-really-formally-introduced acquaintance, but here he was, fucking him like there was no tomorrow.

But in the heat of the moment, Shizuo failed to think of these things. No, he did. He just chose to ignore them. In the back of his head, he prayed that the next morning, everything would be back to normal. The practically-strangers would pass each other in the halls without a glance, and Izaya would move on to someone else.

The last thought caused Shizuo to clench his jaw, but he stopped himself when he remembered that he had no right to be possessive.

So as the blonde stood outside Izaya's door at quarter-to-midnight, he wondered how exactly he had gotten out of there. Shizuo also realized with a jolt, that Mairu, Kururi, and Kasuka hadn't returned. He stood there for a minute or two, somewhat shell-shocked, before taking out his phone and snapping it open.

11:21 p.m. Kasuka: Mairu and Kururi and I are at Karaoke. Go home without me.

Shizuo silently closed the phone. The mere mention of his brother caused him to blush. What would he say if he found out what Shizuo had done tonight? He slapped a hand over his mouth. Normally, he hated violence but he had an extremely strong urge to hit something.

He quickly made his way home, took a quick shower, and slammed the door to his bedroom once he was inside. The loud bang! gave him a sense of satisfaction.

Shizuo slid down to the floor against the door. He could almost still feel Izaya's heat surrounding him, moving, and-

He threw his head back as he realized he was getting hard again. If he could stamp his sexual attraction for Izaya away, he would do so right away. It would do nothing but hurt him. But what was more troublesome was his ordinary attraction for him. It wasn't just sexual. Shizuo had an urge to just be around him. He wanted to observe his quiet beauty- not his sensuality- forever, and keep him for himself.

Izaya woke up the next day with a sore back and dark circles around his eyes. He peered at his reflection in the mirror, and considered attempting to improve his appearance. He wondered if the person he was trying to improve it for would even notice, so he did nothing.

As he made his way to the dining table for breakfast, Mairu and Kururi turned their heads to greet him.

"Ohayou, onii-san!" Mairu called. "Aren't you going to ask how my date with Kasuka was?"

"No." Izaya muttered sourly. Kururi ruffled his hair.

"Did something happen last night? You look like you woke up on the wrong side of the bed this morning."

"Yeah, all because of you two." He grumbled.

Mairu stood up. "Really? Tell us! What happened! Was it with Heiwajima-san?"

Izaya shook his head. "I was just joking. Didn't get a good night's rest, that's all."

"Heeeeh? All right. Make sure you get more sleep tonight then. I hope there won't be any... distractions." Mairu had a glint in her eye, and Izaya suspected that she had an inkling of what went on yesterday.

Izaya shrugged and grabbed the plastic spoon for the rice.

"Come on, let's eat. I'm going to be late for my first lecture."

As Izaya entered the automatic doors of one of his lecture halls, he wondered what sick plan Lady Luck had planned for him today.

A babble of freshman stood in front of the door of the hall, and Izaya resisted an urge to sneer at them. They were laughing loudly and creating a large amount of noise in the empty hallway.

Typical humans.

As he pushed past the group to get to the door, he caught of a glimpse of a 195cm-tall blonde head near the edge of the crowd. He froze, and quickly recovered. Shizuo hadn't spared him a look and Izaya bit his lip as he entered the hall.

What else had he expected? It wasn't as if they were lovers now that they had slept together once. Besides, it was mostly Izaya forcing himself on Shizuo, anyways. Izaya had just been enticing a human reaction out of him.

He walked to the back of the classroom and took a seat. Izaya huffed as the group of freshman entered the room, and the professor took a stand at the podium.

"Today, we're going to have your kouhais sitting in for this lecture. They're getting a taste of what this course is like."

Izaya suspected that it was something like that. He watched Shizuo take a seat near the front- so brave, so honest- and throughout the whole class, he stared at his straight back.

He guessed that was another thing that he loved about Shizuo; His honesty and his bravery. He was never afraid to speak up and bluntly said his opinions. It was the total opposite of him, and Izaya found it extremely endearing.

He tried not to think of the feeling of Shizuo's cock inside of him, but somehow in the middle of the lecture, his daydreams had wound back to the night before.

"So big... so full… H-heiwajima-san…." He moaned.

"Orihara-san, did you hear me?" Izaya jolted up.

"I'm sorry, what?"

"We're going for food now, do you want to join us?"

Normally Izaya would have opted out of this event, but the sight of Shizuo's tall and straight back leaving the room, getting further and further away from him, stirred something within him. He had to catch up.

"Sure. I'll go."

As the small group of students took a seat in the restaurant, Izaya settled for a chair near the end of the table, where he was able to see everyone. After all, human observation was one of his hobbies.

Izaya was distracted during the whole meal, and he barely touched his food. However, when Shizuo suddenly spoke up, Izaya stirred to life.

"Your hand is on mine." Shizuo said blandly to a short and petite girl to his right. She blushed furiously and withdrew it, but it was obvious that she had been trying to make a move on him.

Izaya covered his mouth at his honesty and his stupidity.

"Heiwajima-san, it was so obvious that she was making a move on you." He chuckled.

Shizuo turned towards him and frowned. "I'm not good with advances."

"Hm… like yesterday, right?" Izaya rested his chin on his hand and looked at him expectantly.

Shizuo made a low sound at the back of his throat and drew his eyebrows together. "Let me get this straight Izaya."

Izaya's heartbeat sped up a little. He called me by my first name?

"I don't like you." Shizuo said tonelessly.

"I figured." Izaya grinned but something fell within him. Shizuo stood up, looking at Izaya from above.

"Washroom." He said. Izaya stared at his retreating back, and once again felt the urge to just chase after him. He hated seeing that back sometimes, as it got smaller and smaller, further and further. So he stood up abruptly after Shizuo had left and found himself in the washroom as well.

Shizuo was just leaving as Izaya got to the door, and Izaya crossed his arms.

"Could you take a step back please? I'd like to get in." Shizuo raised an eyebrow, but did as told.

Izaya's eyes swept the floor of the stalls, making sure that there were no other occupants in the stalls. He decided to use whatever sexual attraction Shizuo still held for him to his best advantage.

"So. Would you like to continue?" Izaya heard himself say hollowly.

"Continue what?" Izaya's senses were suddenly heightened and Shizuo's deep voice made his heartbeat speed up even more. He hoped he wasn't going to regret this in the future.

"What we started yesterday."

There was an eerie silence before Shizuo spoke up.

"That already ended."

But Izaya felt himself grab Shizuo's hands and pulled him into the nearest stall. He thanked the Washroom Gods that it was clean, and not smelly, as he quickly grabbed Shizuo's belt and unbuckled it with an almost inhumanly speed.

Shizuo grabbed his wrist roughly.

"What, are you doing." He breathed.

"Just relax." Izaya smiled. He unzipped Shizuo's pants a second time, and dove his hand under his undergarments. Izaya's heart was still beating wildly, just like the first time, and he hoped his nervousness wasn't showing. After all, Izaya had to play the role of the confident one.

He pulled Shizuo's length out of its confines and began to stroke it. A small noise erupted from Shizuo, and he threw his head back against the wall of the stall. The only noises echoing in the washroom were Shizuo's and Izaya's heavy breathing.

As the blonde's cock grew even harder, Izaya looked up at Shizuo's neck, watching a bead of sweat trickle down under his shirt, he felt the sudden urge to lick it. Shizuo lowered his head and Izaya found himself staring at his lips; those expressionless, and hard lips. He wished he had kissed them last night. That might have been the last chance he would have ever gotten.

He swiped a thumb over the leaking tip of Shizuo's cock and spread a bit of precum.

"God…" Shizuo moaned. The sound of his hand slapping on Shizuo's skin increased in speed, and Izaya knew he was coming. He grabbed a tissue with his free hand and felt him come. His hand became sticky and wet, but he kept stroking, letting Shizuo enjoy his orgasm further. After Izaya had stopped, Shizuo looked down, and Izaya stared at him with hooded eyes.

He leaned closer, and tilted his head, but at the last minute, Izaya became frightened. He dropped his gaze and leant back.

Suddenly, he felt a monstrous strength slam him into the opposite side of the stall and he winced as his back hit the hard surface. Shizuo pinned his wrists to the wall and glowered down at him with a furious expression.

"What the hell are you holding back for?" He nearly snarled, and the next thing Izaya could feel was Shizuo's lips on his neck, biting, and nipping.

While he grabbed a few locks of Shizuo's blonde hair, in the back of his head he wondered how their relationship had come to this.

Where had he gone wrong? Why had it come to this?
