The Izayas decided that now was the right time to glue together and rub wet skin against wet skin. Shizuo gritted his teeth.
"Louses only know how to do that."
Izzy splashed to the glowering man and straddled him. Shizuo still wanted to wring the neck but at least he was topping. And there was something to be said about that. Izzy had been wanting to try on this über violent version of his Shizuo since he had laid eyes on him. And what Shizzy didn't know wouldn't hurt him. Shizuo slammed him against the tiles and roughly pushed into him.
Izaya did not want to stay behind so he approached Shizzy and took him fully in the mouth. Shizzy was not expecting this and he moaned loudly as he felt tongue and lips working on his length. Meanwhile Shizuo was having some sort of predicament. His mind was becoming somewhat hazy so if he was to get his revenge against the two dreadful clones, this was the time and he might as well get even with this Shizzy person that was simply an embarrassment all around.
Shizuo grabbed Izzy by the neck and pushed him against the other Izaya.
"Louses should do it with louses, blood hell."
Izzy took the cue right away. He did not get to top everyday and he was most definitely looking forward to it. So he now took the chance to press himself until he was inside Izaya who looked over his shoulder and smiled around the dick that he held in his mouth. Izzy was enjoying the feeling of tightness closing in on him but he forgot about it as soon as Shizuo shoved his big dick inside him. Pain flared up and he jolted forward out of reflex.
"…hurts!"
"You don't say, Izaya."
Izzy was tempted to disclose his identity and inform the crazy Shizuo that he was not that Izaya but he knew that it would be pointless. Not to mention that as soon as Shizuo began to move in and out, his mind went blank, pain mingling with intermittent pleasure. Soon enough he was rocking in tandem with the pendulum-like motion that sent him deep into his counterpart and back at the angry man that filled him to the brim.
Izaya lapped at the dripping pre-cum that oozed from Shizzy's tip and bobbed his head up and down as he layered the entire length with spittle, his mouth covering it whole over and over. Shizzy closed his eyes at the warm feeling that spread from his lower belly to his whole body.
"Fucking louses!"
Shizuo was very angry indeed and he took it out on Izzy by brusquely thrusting into him so that the four of them settled for a steady pace, wet skin becoming hotter with each second. Izaya added pressure to his sucking and swallowed the thick salty liquid that gushed into his mind as Shizzy came. Izaya squirmed as orgasm tided him over in a series of waves that triggered Izzy's own climax as he released into his counterpart. Shizzy was happily floating in his afterglow when Shizuo punched him in the face and sent him flying through a brick wall.
"And fuck you too!"
Shizuo pulled at Izzy's hair hard enough to end with two handfuls of it by the time he was done shooting his seed into him. And he was still rather angry even as he collapsed backwards and sat in the water. The Izayas fell asleep almost immediately, apparently Izzy was not very bothered by the loss of a few strands of his glossy hair. Shizuo got out of the tub and without a warning he picked up Simon and threw him against the awful louses. So much for that nuisance. He left the sentō still grumbling under the breath but he was considerably happier. Shizuo smiled as he lit a cigarette. The hell with this insanity.
Meanwhile, Shinra was having a very interesting conversation.
"Celty, with this device we can visit alternative worlds!"
"'I doubt it. And what good would that do?'"
"Maybe we can find a version of your head in another dimension! Let's try it again."
Shinra pulled a switch. And suddenly found Shizuo found himself surrounded by Izayas. A Tokyo worth of them. Stomping on phones, pretending to ride bikes, turning around in swivel chairs and all along cackling wildly.
"Izaya! I'll kill you! All of you! Even if it takes me the rest of my life!"
The Izayas all chanted in unison.
"Shi-zu-chan~!"
And this was how Heiwajima Shizuo learnt that indeed there was a hell.

The End.
