Pairing: Shizuo/Izaya

Prompt: Izaya's getting frustrated cause he never can predicts Shizuo's actions so he starts stalking him to find his weakness. One day, he finds out more than he wants to. He actually saw Shizuo masturbating while calling, surprisingly, Izaya's name.


9 am. Shizuo wakes up.
Izaya was keeping a log. A mental one, lest he'd be tracked down but he was most definitely serious about his stalking. Because he could never find when the next vending machine was about to hurl in his direction, Izaya had taken to himself to spy on Shizuo and uncover his weakness. Super strength or not everyone had something that could be used against them and Izaya was bound to discover Shizuo's. This morning he was bolder than usual and not only was he perched right across Shizuo's place as he had bugged the place the previous night.
9.15 am. Shizuo grumbles something then reaches under the sheets and-
Izaya zoomed in with his binnacles. Now this was good, Shizuo was beating it off, an occasional groan escaping from him. Thanks to the wonders of technology Izaya could see it all in HD, from the slightly glazed eyes to his impressive erection and its oozing tip. Izaya whistled under his breath.
"Well I'll be damned, Shizu-chan."
"Izaya…"
He nearly dropped the binnacles. For a whole breathless second Izaya was sure that Shizuo had found him out somehow. Then he saw Shizuo tensing suddenly and coming all over the sheets, Izaya's name again on his lips.
"Eh…? Eh?"
Izaya was too stunned to know what to do. Then he smiled wickedly. For a few more days he kept his stalking pattern and eventually it became clear that calling out his name as he 'took care of business' was something of a routine. So one fine morning, after some preparations, Izaya knocked at Shizuo's door, purposefully interrupting his shower. Shizuo answered the door with a towel around his waist and nothing else, his typically angered expression changing into confusion as he saw Izaya.
"What are you doing here?"
"Hello neighbor!"
Izaya offered him an apple pie. Shizuo blinked at it blankly.
"Huh?"
"I just moved last night into the apartment right next to yours."
"Then move again. I don't want to see you around."
Shizuo was about to bang the door on his face.
"My, the walls sure are thin in this building. You can hear everything, really paper thin."
Izaya smiled innocently. Shizuo froze on the spot and was silent for a while.
"What do you mean by everything…?"
"Want some pie? And mind if I come in while I'm at it?"
Shizuo blocked the entrance squarely with his body. Then he had a change of heart, apparently.
"Don't think I'll be giving you any food. Or tea."
"No problem."
Izaya waltzed into the apartment and looked around intently as if he had not seen it from every possible angle when Shizuo wasn't around. Shizuo remained standing as if he did not quite know what to do in his own home.
"What do you mean by everything?"
"Why, everything is…everything, isn't it? That's a tautology. Self explanatory all around."
Shizuo frowned darkly.
"Don't screw with me with your fancy words."
"What about the pie?"
Shizuo threw the apple goodness at Izaya's face. Izaya swept bits of crumb from his eyes, licked the sweet filling from his lips and scooped some with his fingers that he proceeded to slowly lick. Shizuo watched with growing distress.
"Hmm…tasty. I'm such a good baker."
"Get out of my house right now!"
Izaya pouted.
"It's because you're so loud that it's difficult for me to sleep…"
Shizuo started then mumbled awkwardly.
"…no one ever complained so far so it should be fine."
"That's because everyone is terrified of you, Shizu-chan. You can be so scary~"
Shizuo was silence for a while. Then:
"Can you really hear…stuff from your apartment?"
Izaya nodded.
"Yes. Like when you boil water to make tea, when you take a shower, when you watch TV, when you listen to the radio…that kind of thing."
Shizuo seemed a bit relieved.
"Is that all?"
Izaya allowed himself a very sweet smile.
"Everything is everything by definition, is it not? Shi-zu-chan."
"Cut it with the complicated talk."
"Alright."
Izaya licked his fingers some more.
"I also heard you calling out my name a few times."
Shizuo colored immediately. He opened and closed his mouth a few times.
"It's- it's not like that! Don't you go getting the wrong idea now!"
