You were nibbling Optimus' arm, and he was just sitting there, taking it, not flinching. He did grunt a little but made no cries or whimpers, just hums and silence. After a moment, he looked at you. He didn't care if you did this, as it was your natural instinct as a Predacon to do so, it wasn't your fault, and the he knew that, but it probably wouldnt be the best idea to keep letting you chew on him. Perhaps we should indulge in getting you things to chew on, no? He chuckles.
