Eyes locked on Shiki, Izaya moved, slowly, occasionnaly elliciting low groans from the other man.
He was still waiting for the moment he would throw away his pride and simply beg for him to go harder, or anything, really Izaya would be pleased with anything.
Unfortunately for him the yakuza was stubborn, and seeing him flushed, legs spread and arroused under him, Izaya had to admit he was also damn sexy.
Not able to take it anymore he suddenly increased his pace, making the other gasp in surprise and pleasure.
They both were heavily panting, messy hairs falling in front of their eyes.
Izaya took Shiki's cock gently in his hand as he continued to pound into him, slowly caressing the hot flesh, grinning when he felt precum coating his fingers.
The yakuza's vision started to become hazy, moans escaping his lips, his hips moving in tandem with Izaya's movements, increasing the friction between their bodies.
The informant firmly palmed his partner's erection and pumped.
First slowly, then faster as he felt his own release come closer and closer.
Coming into Shiki he leaned down and kissed the man, feeling him releasing between their bodies.
When they broke the kiss, Izaya trailed his tongue one last time down Shiki's body, licking a bit of the cum spread on his stomach, talking as he struggled to get his voice back, "Shiki-san tastes so good~"
The man didn't answer and instead ran a hand in the informant's sweaty hairs.
he smiled as he leaned down to bury his head in the crook of Shiki's neck, distractingly running his hand in his torso.
"Shiki-san?"
"Mmh?", his voice was low and he seemed tired.
"You were really good Shiki-san"
Izaya wasn't even sure the man heard him, when he turned his head back to him, his eyes were shut and he seemed asleep.
He smiled and shrugged, putting a blanket on the sleeping body and exiting the room as quietly as he could.
He had more work to do but first came two very important things.
A shower.
And second, making sure everything had been recorded properly. It'd be a shame if he couldn't see Shiki's aroused face anymore, or better, blackmail him with the video later.
He softly hummed a song called Subarashi Hibi as the water of the shower fell down on him.
