The day was a normal day in Orihara Izaya's life. He had went to school, had been bored in school, observed humans and somehow tried to relieve his boredom, playing with a particular human who wasn't exactly one, namely Heiwajima Shizuo.
Their chase in the streets of Ikebukuro were always tiring, so whenever they had one, Orihara Izaya always went home by train.
He didn't mind that much, trains were fabulous to observe humans, there were so many different kinds of them there. He was almost ready to call trains his personnal paradise, trains and streets, his two favorite playgrounds.
Lost in his thoughts he didn't realize immediately that someone was touching his ass.
Trains were crowded, accidents happen, so does accidentaly bumping into someone.
However in that particular case there was no mistake anymore. That person was touching him. Really touching him.
He had witnessed this kind of behavior in his past observations but it never happened to a boy before, it shouldn't happen now either.
And worse of it all, him, the great Orihara Izaya, had no idea about how to react to this kind of situation. If he was a girl he would have screamed and while he normally enjoyed attention, this situation definitely wasn't one he wanted anyone to know about.
While he was desperately thinking about how to smoothly get out of this situation, the hand became more insistent, rubbing harder at the tender flesh, gropping him.
He endured in silence, hoping that whoever that person was he'd get out of the train at the next stop.
When the doors opened the touching stopped. For a moment he thought he was free but the hand quickly came back, much to his displeasure.
It was running in his ass and he couldn't help but shiver as it made its way under his pants.
He had to do something, he couldn't let a random stranger touch him, that was unworthy of him.
He jolted as he felt hot breath against his ear and a low voice whispering,
"Don't you like that yet, kid?"
In horror he realized that the stranger's other hand was now going dangerously close to his cock.
As he was about to scream the hands suddenly stopped and a cold voice echoed in his ears.
"What do you think you're doing scum?"
"Nothing, nothing, I'm sorry Sir"
"Disapear"
Frozen in place, blush on his features, Izaya did not dare to move an inch, he was startled when a hand went to rest on his shoulder and that same cold voice asked,
"Are you OK?"
He couldn't talk and just nodded, turning back to the stranger to bow and whisper "Thank you"
"It's nothing. What's your name?"
"Orihara Izaya"
"I'm Shiki-san, nice to meet you"
"Nice to meet you too", he smiled.
For a few more minutes they stayed silent, nearing his stop Izaya took a deep breath and said,
"This is my stop. Good bye and thank you again. I'll repay you one day"
Shiki just nodded as he smiled knowingly.
