Four months

It's been four months since their first date and everything's changed. They talk constantly, going out as 'friends' on a regular basis. While both noticed the sudden change, neither did anything to stop or mention it. Although Izaya was reluctant to admit how being around Shizuo had affected his emotions, he was slowly starting to open his mind to the idea of actually liking the monster of Ikebukuro. They usually hung out in Shinjuku to avoid drawing attention- well more than they already did with their everyday chases. Which, of course they still participated in but it was no longer a murderous game of cat and mouse, instead it was just a game of chase between them. Tag for grownups.

The both of them had discussed their ongoing rivalry and even though they still called each other names or said I hate you. It was a relationship in the making

"Tom's outta town for a few weeks and the big boss doesn't trust me to work under anyone else." Sharing his day with Izaya had unintentionally become one of his favorite things. While the flea was still a sarcastic asshole he knew how to listen. Sometimes turning simple everyday conversation into something exciting and interesting.

"An informant's job is never done. There's always new information waiting to be learned." Izaya spoke from behind his desk. Shizuo was seated on the desk facing the window, while Izaya sat in his favorite chair, spinning in slow circles. Sometimes he stopped to look at Shizuo or just glance at the sun slowly going down. "But I enjoy it so much it hardly feels like a job at this point."

"It's a dirty job." Shizuo grunted, glancing down at the smirking flea already knowing the others response.

"As if yours isn't." The twisted smile grew." C'mon beating people up for a living, you could do better than that can't you? Oh wait..." Shizuo growled while Izaya just laughed, titling his head back and letting it flow out without a care. Shizuo kicked his chair, sending it scraping against the wood as Izaya flew a few feet back.

Izaya stomped his feet down to stop himself before he crashed into the wall, turning himself around, he kicked the floor hard enough to send himself rolling back over to his desk, this time out of reach of Shizuos leg. They continued to joke around with each other while longer until they both agreed they could use something to eat.

"You got anything in the fridge?" Shizuo asked already on the move to Izayas kitchen. He had been there enough times and had been forced to get his own food on several different occasions so he had a pretty good idea of where everything was at. Opening the large silver refrigerator he was almost disappointed. Stupid fatty tuna was everywhere, bottles of water, vegetables and other healthy things. But when it looked like all hope was lost, he spotted a small slice of strawberry cheese cake hidden behind a carton of milk.

"You stay here so often I thought I should start putting small treats in there for you." He said from right behind Shizuo. "There's the cereal you like in the cupboard and I got a few pudding cups." He laughed when Shizuo glared at him. One of the first things Izaya had asked about was when Shizuo first realized he was super strong and the following story had made him laughed so hard Shizuo had punched him.

….

They were seated at the table, Izaya was eating one of the pudding cups and Shizuo slowly savored the cake. Although he had been in the mood for something warm and Izaya-made, the store bought cheese cake hit the spot.

"So how long are you going to be out of work anyway?" Izaya was genuinely curious, even though the other spent most of his time over Izayas house he still had bills to pay didn't he? He looked over to Shizuo while letting the spoon dangle from his mouth.

"Dunno. He just said a few weeks." Izaya rolled his eyes, muttering under his breath. "What?" He looked up from his cake to glare at him for mumbling.

"I find it a little weird that you just let your boss run off to another town without any knowledge of when he'll return." He sarcastically replied, taking another spoonful of pudding and making a loud tink sound as he shoved it in his mouth.

"Shut up. It's not like I care." At that Izaya immediately brought up his rent and other bills. "I can just find a part-time job until he gets back." He had it all planned out. Izaya nearly rolled his eyes but stopped himself; Shizuo would likely throw something at him. About to reply with another smart remark an idea popped into his head.

"Work here."

"What?"

"Work." He paused. "Here. It'll be fun, maybe you can be my personal body guard." He snickered at himself. But he averted his eyes to the pudding cup. He was suddenly self-conscious about himself. He could feel Shizuo looking at him, studying him. He felt like an animal being held to a table as a doctor dissected the body. He was about to take it back when-

"Are you being serious?" Shizuos voice seemed to deepen and his eyes were staring into his when he turned to face him.

"Of course I am." He forced himself to hold the gaze. "C'mon we're together all the time, might as well help me out while you're here. Clients try to get rough all the time. You can save me a bit of effort by just toss'em out the door." He chuckled to hide his anxiousness.

Talking and spending so much time with Izaya so often had let him in on little clues. Maybe it was because Izaya was always paying attention to small details and Shizuo had started doing it himself, he wasn't sure. But he had noticed Izaya had a nervous tick of his own, whenever he was antsy or uncomfortable he would twist the ring on his index finger back and forth with his thumb. Another was staring at you until you just agreed. And he was doing both at the moment.

"We really have come a long way." He blurted out of the blue.

"What do you mean?" Shizuo took a bit to give himself a moment to think. Trying to find the right words. He didn't want Izaya teasing him about this.

"..I mean… We went from being enemy's to nearly best friends in only a few months." Although the two had talked about numerous topics they hadn't really approached the one about their new found friendship. The air seemed to turn a little awkward for a moment.

"It's natural after spending so much time together and most of it was rather intimate. Not to mention when we first met we hated each other to the point of murder so there weren't many chances to find out what we had in common or anything along those lines." He shrugged nonchalantly, dismissing the awkward atmosphere all together. Shizuo had taken notice of Izayas ability to take an uncomfortable situation and just make it disappear. Sometimes he was grateful.

"Yeah but we were enemies! For like- eight years." Shizuo waved his hands dramatically. How could Izaya just push this to the side so easily?

"Were? Why past tense?" Izaya smirked. "Don't tell me I've won you over Shizu-chan." It wasn't really a question especially with the way Izaya was looking at the other.

"I hate you." Shizuo shoved another piece of cake in his mouth. He didn't notice the sneaky subject change or the curious glint in Izayas eyes.

"Hate you too Shizu-chan~." He sung, eating the rest of his pudding.

….

Shizuo ended up staying the night-which was normal these days. They hadn't had sex when they went to bed so Shizuo had assumed when they woke up they would do it than. Izaya had made the same assumption. But as their eyes flickered open and they glanced to each other, whispering good mornings and leaning in to share an intimate kiss, Shizuo moving to pull Izayas leg over his waist rubbing the soft flesh and as things started to heat up something horrible happened.

"Izaya." A voice of a woman rang throughout the apartment; monotone and irritated was the way Shizuo would say it sounded. The one called for groaned as he shoved his head into the space where Shizuos neck and shoulder met. Shizuo wasn't sure what to do; he knew the woman out in the other room was called Namie she sounded just how the flea had described her.

"I hate her so much right now." Izaya grumbled, biting into Shizuos neck to prove his point, the other hissed and moved his hand to slap Izaya on the back of the head but Shizuos own hand shot out and pinned it to the bed. Of course Shizuo could have pushed out of it but instead he just raised an eyebrow at the other who replied with a smirk in return. Slowly Izaya lifted himself until he was hunched over Shizuo, one hand laid on his chest and the other holding his wrist to the bed, while his legs were on either side of Shizuos waist. He slid his body down until their members were pressing against each other.

Shizuo started to move around, ready to rip his hand away to push the other off, but Izaya stopped any movement when he started to grind his body down onto Shizuos. Moving his hips in a circular motion and then back 'n' forth. Slowly and sensually, leaning in slowly to kiss the place he had bitten.

"I-Iz…"Shizuo gasped when something wet licked up to his ear. The grinding didn't stop even as Izaya played with other parts of Shizuos body. Any spot he bite he apologized with a soft kiss.

"Izaya!" The womans voice sounded again this time closer than before, Shizuo panicked and tried to throw the other off while minding his strength, but his kindness was his downfall in this situation. When he pulled his hand out of Izayas grip and moved bothe hands to the flea waist to push him off Izaya pressed down harder stopping Shizuos efforts. Because Shizuo wore nothing but pajama pants to bed Izaya could feel his member perfectly through the clothing. Reaching a hand of his own between the two of them as he sat back up, messing with the elastic band for a moment.

"Come on, it'll be funny." He whispered seductively as he pulled his hand away, instead pulling off his oversized t-shirt-a shirt that Shizuo was pretty shore belonged to him. Running a hand down his own body Izaya moaned at the gentle touch of himself. Rocking against Shizuo for added pleasure, he used both hands to rub at his sides, neck, back anywhere he could reach. He had Shizuo hooked.

The man had a hungry look in his eyes and his mouth was practically hanging open, Izaya would have laughed if his angry secretary wasn't about to slam open the door. Speaking of angry assistants-

"Izaya if you're asleep I'm dump-"Izaya purposely moaned as loud as he could, cutting the woman off completely. She sounded as if she were right outside his door, ready to walk in but now she was probably in shock.

Deciding to have a little more fun he rocked his hips faster, until the headboard was knocking into the wall making a loud thumping noise. "Oh..SHizu...haRDer..PleASe" Letting his voice rise and lower at different parts of his words he could barely keep it up as his body started to shake with laughter. Everything stopped when two hands gripped his hips, stilling all movement. When he looked down he was met with a very angry looking Shizuo. "Oh come on." Izaya sighed as he fell to the side, rolling off Shizuo completely. Shizuo sat up, glaring at Izaya.

Neither said anything but Izaya knew he was going to be yelled at soon so he just lifted himself out of bed and started gathering some clothes keeping his back to him. Things stayed like that until Izaya had everything he needed.

"Contrary to popular belief I can't read minds, if you have something to say. Say it." He turned to finally face the other. The truth was he didn't like it when Shizuo was upset with him. At least not anymore. Or maybe it was just situations like this, he didn't know. All he knew for suyre was at the moment Shizuo was unhappy woith him which in turn made him unhappy with himself. Which didn't make sense.

"Don't use me to mess with people." He growled out, glaring with the same old hate he used to look at Izaya with. His fists were clenched tightly on his thighs. Izaya could see he was shaking slightly, and immeadiatly regretted what he had done.

"Shizu-cha-"

"Don't call me that!" He shouted pushing himself out of bed and starting to search for his clothes. "I should have known you wouldn't change. A flea like you will always be a manipulating bastard." He grounded out between clenched teeth. Pulling ont his dress pants over the silk pajama pants-Izaya bought them. Grabbing the shirt Izaya had been wearing and tossing it over his head, almost ripping it as he pushed his arms through.

"Shizuo what are you doing?" Izaya suddenly felt his heart slow, his own body starting to shake at what he knew was happening. He watched the other tug on his clothes, reaching his hand out to stop him but it was as if his body stopped listening to his commands. "Why are you getting so upset right now? Its not like you've never seen me play with people before. What's the big deal all of the sudden?"

"That doesn't make it right! It doesn't mean I'm okay with it just because I don't say anything. You just- Argh! I don't want you using me to fuck with other people, I don't want to be a part of something like that." He searched for his socks but could only find one, giving up he pulled on his vest and bow tie and started to head for the door.

"Why are you leaving?" Izaya found himself in that moment as he stomped over to Shizuo and forced him to face him. Izaya studied the others face with narrowed eyes. "Whats this really about?" He could see the doubt in Shizuos eyes. This wasn't about messing with people at least not entirely.

"What are you talking about?" Shizuo played cool, looking to the side, completely ignoring the informant.

"I don't doubt you are angry about my games with others but the Shizu-chan I know wouldhave said something long ago. So what re you realkly getting heated about? Is it namie and how close we are, Because I can assure you, we despise each other." He waved his arm about and shut his eyes as if he had solved the puzzle.

Shizuo should have just let him hasve his glory and go on to have a hot a tastey breakfeast but instead he dicided to open his mouth and tell the truth. "I don't want to be friends anymore." He whispered. Izayaz reaction was instant, mouth drawn in a tight line, body tensed and his ams crossed. He was puuting up another barrier. "Its not enough to just be near you anymore. I want more." He hoped it would clarify things.

"More? What more can you get from me Shizuo!" He shouted, gesturting to himself wildly. " We are together all the time, you stay at my apartment more than your own, for godsake we have sex. We're practically dating!"

"Practically." Shizuo looked to him saw the realization dawn on before he could say anything he pulled the smaller man closer and kissed him. Nothing more than a touch of lips for a few second until Izaya pulled back.

"You want to date me?" He asked stunned. Shizuo just nodded, sighing when he felt a huge weight lift from his mind, healmost seemed to sag.

"I know you don't like relationships but.." Shizuo pulled a hand away to run through his hair as he looked off to the side.

"Shizuo." Izaya said not letting Shizuo finish."I-I don't love you." He looked up at Shizuo and although it didn't show, he wanted to cry. The words hurt coming out as if they were a lie.

"I don't love you either." He missed the hurt look on Izayas face. "hell I'm not ever sure I know what love is. I've never been in love or anything like that. All I know is when I'm with you I'm happy…" He paused. "I'm calm."

Izaya searched hmis eyes for something,. Anything but all he found was hope mixed with a little fear. "I'm not sure what you want me to say."

"I want you to say you'll go on a date with me tomorrow night as my boyfrienbd." Shizuo grinned childishly at hims and it grew wider as Izaya gave a small smile of his own. But the small smile soon grew into a smirk.

"So make-up sex?" His reply was a smack to the head. Shizuo called him a flea and Izaya called hima brute and things went on like that. They had there ups and downs of course but they safter , they were Shizuo and Izaya.
