Three Sentence Ficathon

They'd fought the same fight they had for eons, bellowed the same arguments they had for eons, over a stretch of rusted metal that didn't even matter in the end, and when the fight went badly for the Autobots Optimus was deeply annoyed to find himself captured instead of deactivaged, for he knew from eons of experience that it meant Megatron wanted to continue their 'debate' in a more intimate setting.

"I'm tired, Megatron," Optimus rumbled resentfully once the Slagmaker had him alone. "Do as you will, but no more words tonight."

And Megatron frowned, but took him at his word; their coupling was fierce and merciless and powerful enough to make the lights flicker, and while Optimus was sure Megatron would have preferred his rival put up more of a fight, he was at least enough of a gentlemech to pin Optimus down and give him satisfaction worth the pain.
