Shiki struggled into the kiss, not to get away but for his pride, not to let Izaya think he would give up so easily.
Leaving Izaya looking for his own tongue, he licked back as soon as the muscles met, feeling his head free to move again and hands back on his body he moaned into the other's mouth and put his arms around the informant's neck, moving one hand to his hairs, desperately clutching at them while the other hand grabbed his neck, slowly caressing the skin, sliding a hand underneath the shirt, smirking when Izaya released a cry of surprise at the feeling of nails digging in his back.
When the informant pulled away from the kiss, both of them were panting, stilling for a moment in an attempt of catching their breath.
During that short pause, Izaya sat up and removed his shirt, an amused smile growing on his lips as he remarked the intense gaze of the other man on him.
"Does Shiki-san want to touch~?"
He chuckled when the only answer he received was an annoyed growl.
His hands were idly resting on his chest, still smiling Izaya threw his shirt on the floor and took Shiki's hands in his. He curiously let the other man guide them on his torso.
Following Izaya's movements, he was discovering the other's body, caressing the smooth skin, feeling him shiver under the tentative touches, always accompanied by the light weight of Izaya's hands on his owns.
The informant let out a barely audible whisper "Shiki-san can touch everywhere, even down there", and Shiki felt his hands guided to the lower parts of Izaya's body, reaching the other's own erection, making him gasp under the touch.
Shiki sat up, pulling Izaya on his laps, "Shiki-san, what are you doing?"
"Nothing"
Relieved, the informant relaxed when he felt thos hands reaching for his pants and unzipping them, he lifted himself up a little and helped him removing his trousers and underwears.
Izaya chuckled, "So, is Shiki-san really getting into this now?"
"Shut up"
This answer didn't stop him from lightly laughing, "Don't forget that even naked I'm still stronger than you though and that ..."
His talk was interrupted by the feeling of a tongue on his neck and he moaned under the wet sensation.
Lightly panting he pushed the yakuza back on the bed, "Don't think I am not enjoying this Shiki-san, but I don't think it's fair if I'm the only one naked here, do you?"
Having said that his hands reached for Shiki's crotch and his mouth went back on his, tongue asking for entrance and teeth lightly nipping at his lips.
