"Hmm. It can, yes. It can be even worse, if you say it wrong." Optimus chuckled, recalling memories of times where attempts at sexiness fell flat, either from a partner or - Primus forbid - himself.

It had still happened any number of times.


But that was the exact opposite of what he wanted to do here, of course. Despite Cliffjumper's obvious squirming about it, he wasn't laughing. So Optimus simply purred and continued to touch, for now fighting the urge to murmur something filthy up against the minibot's audial just to see how he might react next.

It wasn't much, but he could feel that faint tremble in the other mech's chest; see the lines of armor seams not quite as tight as they could be. Optimus rumbled, a pleased grin crawling over his lips as he leaned closer, pressing faceplates to Cliffjumper's chest.

"Mhmmm. Well, isn't this lovely..."

He licked a stripe up the trembling center line, before venting heat back on it, fingers tapping out a eager rhythm on his hip circuits.
