Optimus smiled widely, honest pleasure in his optics.

"You find me attractive?" His engine rumbled pleasantly, and he couldn't resist a lazy stretch that only served to highlight his frame. "You flatter me. But you don't need to worry. I'm not going to do anything I don't want to do - nor anything you don't want to do, either."

Given Cliffjumper's obvious hesitation, Optimus is still flat on his back; keeping himself relaxed, casually sprawled out below the shy mech's optic level. Telling him, without words, that he is still in control, and can do - or don't - as he wills. Intimidating the little mech into anything was his last possible intention; tempting him with his frame, putting himself coyly on display, however, was something else entirely.

"My function here is your bodyguard, of course, and I have not been ordered to serve you in any other way." Directly, at least. "But I cannot deny that I have become fond of you over the past few days, and I would certainly not find it a displeasure."

He smiled kindly, fingertips curling at Cliffjumper's back gently while making no other move.
