I forget who first suggested this, but I wrote it all the same ^^

"But it just isn't natural!" Roy protested weakly, throwing a hand up to shove him away. Unfortunately, flesh was no match for the strength of automail, and both arms were twisted behind his back in two seconds flat, caught in a vise-grip he had no prayer of breaking.
"I said, I want you to FUCK me!" Edward growled again. He punctuated it with a nip, and despite his complete lack of interest Roy couldn't help but shiver.
Ed looked at him through hooded eyes and scowled, proving to Roy once and for all that yes, someone could look horny and murderous at the same time.
"Me, you, right here, right now. What part of that so hard to understand!?" The boy huffed.
"NO, Fullmetal." Roy said adamantly, thrashing violently in Ed's iron grip. "No."
"Please?" Ed whimpered, and pressed himself up against Roy's thigh. To his horror, Roy realized there was something hard there, unmistakeable proof that Edward was serious.
"Fuck me." The boy pleaded again, and nibbled his way along Roy's neck.
"I can't." Roy hissed, even though there was a twitching between his legs that beyond all reason said he could...and a talented hand, working on his thigh, that told him yes, yes he would.
It still didn't mean he had to be happy about it.
"Fullmetal, we have to sleep SOMETIME!" Roy finally cried, desperate. "IT'S FOUR IN THE MORNING!"
Ed paused to consider.
"Engh, maybe tomorrow." Ed replied breezily, and straddled his commanding officer for the seventh time in a row.

I mean, after all, the fandom's more or less decided that Ed's a sex machine... :D
