Sarin: YAOI WARNING! Seriously, if you don't like, don't read. If you like the story without the yaoi then skip this chapter for a boring finisher.
Izaya's face was getting hotter and hotter as time passed. His room wasn't far enough away from the living room that he couldn't hear the girls through the walls. He hoped that Shizuo was better at ignoring it, or else things would get weird.
No such luck. Shizuo felt the exact same as the brunette. He was trying to keep a poker-face, but his face was quickly growing redder with each sound he overheard. He was about to leave, under the pretense of going to out smoke, when he saw the way the noises were affecting the flea.
As if the moans of pleasure weren't enough, the look on the flea's face made Shizuo lose it. He felt his blood travel south, and was up in and instant to go and take care of it in the bathroom. Only then did he remember that he didn't know where the bathroom was and would have to ask the flea.
Izaya looked up as the blonde moved, hoping for something to focus on instead of the sounds that were gradually making him more excited than he needed to be when stuck with the monster. Instead, his eyes saw the other man's reaction to the girls' noises and he hurried to try and hide his own excitement.
"Getting excited, Shizu-chan?" Izaya teased, begging that Shizuo was too slow to notice his similar situation.
"Shut it flea," Shizuo barked, "just tell me where the bathroom is and…" His voice trailed off. His eyes had previously been looking anywhere except at the flea, but when they landed on him after a round of the room he saw something ridiculously funny and yet not. "You too huh?" he asked in a voice as emotionless as he could make it.
Izaya's face seemed to heat up even more and he stood hastily to fight against his rival. "Don't say that so casually!" he gasped. "One would almost think—"
He cut himself off, not wanting to go down that path. He glanced at the protozoan, hoping he hadn't heard the implied ending of the sentence.
Again, no such luck. Shizuo's face became blank, obviously thinking through what Izaya had said. Izaya cursed his luck. Who knew that the protozoan was so observant?
Shizuo shoved Izaya onto the couch, shifting to be lengthways for comfort.
"What the hell are you—!" Izaya started shouting.
He was cut off when Shizuo's mouth covered his, effectively killing the exclamation at its source. Izaya tried to shove the stronger man off, but Shizuo was possessed, not giving up for anyone. They separated to breathe, but Shizuo again cut off Izaya's protest before it was finished.
Izaya felt embarrassingly weak, not even able to fend off his rival. His knives were on his desk, and he doubted the monster would allow him time to go and get them.
Shizuo was growing impatient. He felt the need in his groin and wanted it sated. He moved his hands to Izaya's nipples, knowing they would make the flea as crazy in need as he was. The other man broke away from their kiss to gasp and moan, trying to push away but without any force now.
Shizuo smirked as he kissed the flea again. He let go of the other man's nipples, feeling them hard against his own chest as he pressed himself against Izaya. He pushed down on the flea with his chest, but at the same time moved his hand down to grab the other's need.
Izaya gasped at the new pressure he felt on his clothed groin. He tore away from the blonde's kiss, gripping the other man's shoulders in pure need. He hated how weak he was, giving in to the monster as easily as he was, but if it fixed the painful need then he could deal with the results later.
Shizuo used his hand to lower the other man's clothes, allowing him better access in order to pleasure the man underneath him. He heard Izaya hiss at the cold, and moved his face to the flea's neck. He jerked the other man's member, sucking on the flea's neck at the same time.
Izaya gasped and dug his short fingernails into the other man's shoulder. He didn't know if he felt more embarrassment or pleasure, only that it made him want more. And soon!
Shizuo continued to stroke the man, reveling in the gasps and groans that tore from Izaya's throat. One he felt that the brunette was close he stopped. Ceasing his hand's motions, he released his shoulders from the flea's grip and turned the flea around to face the couch.
"Wha—?" the flea began in a moan.
Shizuo cut him off when he inserted the first finger into the flea's entrance. The flea gasped at the suddenness, but didn't complain as Shizuo inserted another finger, and then another.
Shizuo noticed the flea's toes and fingers curled in pain, and smirked as he finished his preparations. He leaned over the flea and whispered into the other's ear, "Don't worry. It'll feel good again soon."
Without further warning, he removed the only barriers between his need and the flea, and shoved himself into the smaller man. Feeling a little too much eagerness, Shizuo fully sheathed himself in his partner, making the other man gasp in pain.
Izaya felt like his insides were being ripped apart. He bit down on the couch's arm, not caring if he damaged it at all. Once he was used to the feeling of Shizuo inside him, he relaxed his jaw and said, "Get it over with."
Shizuo didn't need any more encouragement. He pulled himself out until just his head was inside, and then shoved himself inside again. It didn't take him long to find his partner's prostate, and then he managed to hit there almost every time.
Izaya felt Shizuo against his back, and every time the blonde hit a certain spot it sent a wave of bliss through him. His own need felt neglected, so he moved his hand to take care of it. Shizuo's hand met his, and together they matched the other man's rhythm.
Not much later, they both came. In his ecstasy Izaya screamed out, "SHIZUO!" gasping as the ecstasy slowly faded and left him feeling tired. Shizuo climaxed just after the flea, grunting in pleasure as he shot hot liquid into the smaller man.
Shizuo pulled out and fell back onto the couch, breathing deeply. Izaya kicked off the pants and boxers that still clung to his feet, and fell down as well.
After a while, Izaya moved closer to the blonde, resting his head on the bigger man's chest.
"Oi!" Shizuo complained, leaning up in his elbows to look at the other man better.
"Shut up," Izaya growled. "My ass is going to hurt, and it's your fault."
Shizuo let his complaint die and just laid back down, enjoying the mixed feelings of what had just happened.
