Summary: “Back to taking one for the team then, Fullmetal?” he murmured when Edward was standing next to him. Edward then thoughtfully stood on Roy's foot with his left one, and it was all Roy could do not to whimper.

“This is so weird,” Catie said, as Edward ground up against her – him. He was now a 'he' – when the transmutation had rebounded it had somehow scrambled his gender completely and now she had become a he. A just-so-slightly-taller-than-his-boyfriend he, which was rather amusing given that in his correct body Catie was just a touch shorter than Edward.

And now they were gonna have sex, probably, and he was completely weirded the hell out by this. But at the same time it felt good, good in a totally different way. Edward had his automail hand flat on the wall beside Catie's head. Both of their heads were tilted down, foreheads pressed together, their noses brushing as Edward pressed his clothed groin against Catie's. It was such a strange sensation, the pressure there was so good that he was letting little panting gasps go into Edward's open mouth.

They had gone without for almost two weeks. Sure, Catie had touched himself already – hell, the first day that this had happened he locked himself in the bathroom to see exactly how well the plumbing worked. For an hour. And then, of course, the both of them had been poring over as many books as possible to try to find a way to change him back – as interesting as this little experiment in gender psychology was, Catie wanted to be a she again.

Edward was horny, and Catie had volunteered to suck him off. He did not have any qualms about giving him as many blow jobs as he wanted, even when he was like this – and he had apparently forgotten that Edward was very bisexual because suddenly he was not shy about putting his mouth on Catie's body, regardless of the bits and pieces involved. He had walked Catie right back against the wall, grinding their bodies together and Catie was so turned on that his pants had turned far too tight, and now they actually hurt.

He was hesitant, though. Edward was not, one hand up Catie's shirt, fingers running over his now-flat chest – he was not cut like Edward was, but he was not in bad shape either; just faint muscle definition but Edward's fingers were soft and exploratory and their eyes were on each other. “It's okay,” Edward breathed, flesh hand resting now on Catie's hip. “We don't have to do anything you don't want to....”

“I want to,” Catie murmured. “I just, it's different, you know? But I want to-” the blush hit him pretty hard. “Will you, will you suck me...?”

“Thought you'd never ask,” Edward said, hand slipping into the front of his pants to unfasten Catie's trousers. “I've wanted to taste you since this happened, see if it tasted the same or not.” He was grinning, Edward was a scientist first and foremost and sometimes nothing excited him more than the anticipation of discovery. Catie gripped the wall as he extracted Catie's cock from the confines of his pants and then sank to his knees in front of him.

This was insane. Catie was watching, nearly dumbfounded as Edward traced the head of his cock with his tongue, savoring the taste thoughtfully. “Kinda the same,” Edward confirmed after a moment. His gold eyes flicked up to Catie's and he was grinning infectiously. Then he opened his mouth and swallowed him down, giving Catie effectively the first blow job of his (short, male) life.

Edward was really, really good with his mouth. Catie already knew that, he could sing the praises of the dexterity of Edward's tongue before this, but now he was mapping every inch of his cock with his tongue, almost humming with anticipation as he deep-throated him. Catie twisted one hand in his hair, the other still held back against the wall as he watched him, trying to match action to sensation.

This particular encounter was never fated to last long, and they both knew it. Edward's false hand squeezed his thigh in anticipation as Catie let out a guttural noise and came.

The whole world went white for just a brief second. This orgasm was different, it started at the base of his spine and expanded outwards. Catie knocked his head back against the wall, gasping for breath. When he finally looked down at Edward, Edward was still grinning like the cat who ate the canary. “Good?”

“Fuckin',” Catie said, words missing from his vocabulary. He must have jerked back a little at the last second, because while Edward was wiping some overspill from his mouth there was still a track of white traced across his cheek. Catie rested his hand on Edward's face, smearing the strand with his thumb. “Ed, that was fuckin' amazing.”

Edward kissed the tip of his poor, worn-out cock. “Glad you enjoyed yourself.”

Catie did not move his hand. “So are we gonna have, like, real sex?” His stomach clenched a bit as he spoke, because what if Edward didn't want to? He didn't know how he would take that.

Edward frowned. “Oral doesn't count as sex?”

“You know what I meant.” It was strange, looking down at Edward like this. He'd given head on his knees before, but it was different with a vagina, she nearly sat on his shoulders for that. “Penetrative sex.”

He still had his hands on Catie's hips. “Only if you want to,” he said honestly. “I don't want to force you into anything you don't want, like this, I mean... I know you haven't been interested in anal...”

“I want to,” Catie confirmed, squirming a little as Edward stroked his side with his fingertips. “I really want to, but-”

“But?” Edward prompted lazily, working Catie's underwear down off of his hips.

“But I want to fuck you.” Catie's voice was hoarse and very masculine in that moment, and Edward looked up at him, surprised. The blush hit across his face too, then, unexpectedly. Clearly the possibility of that had not crossed his mind yet. His expression was strange, and Catie was worried. “Can I?” There was trepidation in Catie's voice – he obviously wanted to try but the uncertainty of Edward's reaction had made him hesitate.

Edward was quiet a moment, staring up at Catie while he considered this. Catie's face just kept getting redder and redder – he knew that even if Edward denied him this he would gladly get on his back for him, he just had to ask....

“I,” Edward said, and Catie realized that his face had gone a deepening shade of crimson as well. “I didn't know if you'd want to or not, I was wondering-” Catie put a hand on his cheek and Edward let out a little noise into the palm of his hand that made Catie's stomach do a somersault. “I was wondering what you would feel like inside me.”

Catie let out a ragged noise and tugged Edward to his feet. He kissed Edward soundly and Edward let him, putting his arms around Catie's shoulders as Catie groaned into his mouth. Edward was going to let him...

He put both of his arms around Edward's waist and both hands on Edward's ass, squeezing it firmly. Edward did not quite yelp, but he did make a hungry noise into Catie's mouth, before drawing back and staring into his eyes. “Bed?” he gasped.

“Bed,” Catie agreed, squeezing his ass again for good measure.

He was familiar with this, with Edward's body and his cock. Catie flattened both of his hands on Edward's lower stomach, tracing down slowly until they framed his healthy, bobbing erection. He had had his mouth on it just earlier today, he could map the lines of it with his eyes closed.

They were both completely naked. Catie was not as shy about this, Edward had already seen him, he had practically demanded to see him as soon as this happened, just to make sure all of his bits and pieces were intact.

Catie was, in fact, sitting between Edward's legs on his knees, playing a bit with his erection and touching him all over, and trying to get up the courage to start stretching him for penetration. He wanted to do this, he really did … but at the same time he was ridiculously nervous about the idea. What if he did it wrong? What if he hurt Edward? He couldn't stand it.

But Edward had done this before. He was watching Catie quietly, letting him decide what it was that he wanted to do. The lube sat on the bed by Edward's knee, ready and waiting for him.

It was a ritual that he really wasn't that used to, as a woman. Most women made their own natural lubrication, if aroused correctly – Catie got the feeling that Edward kept the lube on hand just on the off-chance that he would finally acquiesce to anal. Well, it was going to come in handy tonight.

Edward guided him gently, his voice a low murmur as he sat up, legs spread wide for Catie. He had his hand on Catie's wrist to direct him as he got started. First one finger, then two – scissoring inside Edward, stretching – and then a third, just to be on the safe side. Catie crooked his fingers and found a rough patch with the very tips and Edward very nearly spasmed, letting out a low, needy noise.

He fell back against the bed, Edward's eyes were closed as he panted aloud. Catie pushed his leg up, all other feelings overridden by the thought that right now he wanted nothing more than to bury himself in Edward. So he adjusted himself against Edward, one hand holding his leg up and the other around his own cock as he prodded him with the tip of his cock.

Catie had honestly never heard Edward make a noise quite like that before. It was wanton and needy and almost complete nonsense. Catie wet his lips and took a deep breath, before sinking into him.

Edward on his back, his knees tucking snug around his hips, hair loose and eyes closed, mouth open just a bit as Catie moved uncertainly. Edward had done this before, of course he had, his past relationship with the Colonel was no longer a secret between them – but the specter of it seemed to loom, and Catie wanted nothing more than to banish that thought, to show Edward that he was owned by someone else entirely now.

“Fuck, fuck,” Edward gasped as Catie thrust. “There, right – do that again-” He shifted his angle at Edward's command, one hand supporting Edward's hips and the other on the mattress to hold him up. This feeling was completely unreal, the warm, wet heat that surrounded him, Edward's legs forming a circle around his body, drawing him in closer and closer – this was what it felt like to be on the giving end and fuck, he liked it.

But then he thought about having Edward inside him again, slow and tender and Catie let out a low moan. Edward's eyes slid open, pools of molten gold through those thick eyelashes and he watched him move. Catie wanted to come again, Edward's ass was so tight it was squeezing him nearly past the point of no return.

He didn't realize how hard he was breathing until he opened his mouth to speak. “Good?” Catie asked, trying to keep the uncertainty out of his voice.

Edward tilted his head back, exposing his throat for Catie. “Don't stop,” he encouraged, his voice gone so very husky. Catie took that open invitation, mouth and teeth on the line of his throat, down to his collarbone; Edward's flesh hand found the back of his neck and yanked at his hair there, neatly destroying the hair-tie. Catie's braid started unraveling almost instantly, red hair spilling forward over his shoulders.

He was so close. Catie put both of his hands on either side of Edward's head and thrust down, wanting in deeper. Edward's arms and legs tightened around his body, trying to get as much skin-on-skin contact as possible as Catie pushed on toward the finish line.

Edward did not make a noise as he came, although through the haze of sex Catie could feel his fingernails break through the skin of his shoulder as he clung to Catie. Catie, on the other hand, let out a long, low noise, burying his face in the space between Edward's shoulder and neck. After a long moment of holding himself up on trembling arms he gave in and just collapsed across Edward, still between his legs.

They lay there, breathing hard for a long while. Then Edward lifted his head, and since Catie didn't seem interested in moving yet, kissed the side of his face.

“Nngh,” Catie said.

“Are you going to get off of me?” Edward asked, his arms now loose around Catie's back.

“Nope.”

Edward made a frustrated noise. “Come on, get off.”

“Already did.” Catie moved his hips in a circular motion, enough so that he could slide out of Edward with a wet sound. He buried his face again and let out a long sigh. “Sleepy.”

“You're not going to sleep on top of me.”

“Yup.” Catie yawned. “Wanna cuddle.”

“You are still such a girl.” Edward nudged him over and Catie finally acquiesced, sliding onto his side and dragging Edward with him. Edward wrapped his arms around Catie, and Catie yawned again.

“Shaddup, you love to cuddle.”

Edward smiled and brushed aside Catie's loose bangs as he drifted off, and kissed his forehead. “I do,” he murmured sleepily. “An' I like cuddlin' too.”

Roy raised an eyebrow at Edward's gait in the morning. It was barely perceptible, the change, but he recognized it all the same. He had wondered if Catie's... situation … would change their relationship and it seemed like that wasn't necessarily the case.

“Back to taking one for the team then, Fullmetal?” he murmured when Edward was standing next to him. Edward then thoughtfully stood on Roy's foot with his left one, and it was all Roy could do not to whimper.

“You deserved that,” Hawkeye told him after Edward had flounced out of the office and Roy was nursing his poor, crushed phalanges.

Maybe he did, but Ed didn't have to use his left foot either.
