Those hands on his scope tantalize him, but it's the quiet request, and the retraction of that panel that summons forth the urgent little moan from Perceptor's vocal processor. He leans in to rub his cheek against Rung's hip to steady himself for a moment as the wave of want swamps him.

"Yes," he agrees, nuzzling Rung's hip and thigh before dipping in to flick his glossa against the tip of Rung's spike. Peerceptor shivers, drawing back just enough that he can flick a brief little glance up at Rung's face. What he sees there makes him groan hungrily, his optics dimming as he leans in again to draw Rung's spike fully into his mouth.

It feels so amazing to see that want, to feel Rung's body heat against him. To be desired. He cups his hands against the backs of Rung's thighs, holding the smaller mech as he licks and suckles against Rung's hot spike with an appreciative moan.
