Delic's soft groan from where he's sitting should be enough to let Psyche know just how grateful he is to play witness to such an erotic sight. Finally, finally he pulls his fingers away from Izaya's rear and strokes himself lazily, using the sight of the two brunettes kissing as material to get his dick nice and hard.

"You're not gonna forget about me, are you, Iza-chan?" His voice is little more than a husky rumble against the nape of Izaya's neck, which he mouths at almost possessively before parting his lips and biting down, sharp. Probably not as bad as Shizu-chan could do, but it was enough to let Izaya know he was still there.
