Oh no, kiss number two. Although this time, Optimus is prepared for it as he feels those lips press against his faceplate, eyes widening once again. His arms branch out to the bot's elbows, gripping them as he pulls away, slightly.

"I'll say it again, partner. You're intoxicated." Because...Roller would never say these things, not out loud.

His eyes cast down, as if the kiss was undeserved from the get go. "You're memorable too. I never forgot you after you disappeared."

Seriously, just ask what he named his trailer. You won't BELIEVE what he answers with!
