This amused me greatly, because Roy can be such a bastard. And I can so see Jean and Roy fighting for dominance. Which is why they have Cain to balance them out! o
Be careful what you ask, because sometimes it's better off not knowing.
Or
Jean is not an uke!
He could feel the question eating away at his insides, slowly like a cancer until it consumed him whole. It all started with a comment thrown by a tactless Breda, not realizing the impact it would have on the poor younger man. So that was why he was sitting at his/Roy's/Jean's (they all lost track of who's was who's, by this point) kitchen table, staring at a mug of tea that had long since chilled.
It was the scraping of a chair across the tile that finally roused him from his internal pondering. Looking up to meet the black eyes of one of his lovers (that sounded so weird, Cain didn't even know where to start), Fury felt the cancer morph into a fiery inferno that consumed him to the core.
It was time to ask the Question.
"Roy, err, why did you and Jean pick me?"
A cheesy grin, like the one he used when talking about miniskirts in the military, spread across the normally cold alchemist's face, one that made Cain sweat from anxiety.
"Because I knew you would never fight me for dominance. Jean's always like 'it's my turn to be on top' or 'I'm not some God-damned woman, Mustang!' You, on the other hand, are the perfect partner because you know I'm alpha and that I am the boss! You are the one that helps me let Jean think he has some semblance of dominance."
Roy evil cackle was cut off when a heavy hand landed on his shoulder. Looking up into the not too happy eyes of his second lieutenant, the Flame Alchemist felt an icy chill run up his spine.
"You, Master, are sleeping up the couch tonight. And if you even think about using alchemy I'm going to tell Hawkeye about the little paperwork 'mishap'."
And with that, Jean dragged a blushing Cain upstairs and left a pouting Roy at the table.
