Humming, in agreement or amusement, Megatron settled back against the wall again, optics darkening at the building friction... and charge. Chcukling when Orion basically welded himself to his front, Megatron spread his hands over that shapely aft and pushed Orion against himself.

"It's useful for exchanging short messages that can't be tracked or overheard," Megatron said with a shrug of his own, smiling at the feel of Orion's smile against his jaw, "it's forbidden to kiss during fights in the arena for that reason."

The kissing itself had been used as a way to whip up some drama and reaction from the audience, but that kissing had been used one time too many in matches where one fighter had been suspected of folding.

So, regardless of the gesture's popularity, it'd been expressly forbidden in the rules.
