Winry has a new invention that she wants Edward to help her test out. 

When you say the phrase “thinking outside the box”, and you know Winry Rockbell, the face of the pretty blonde mechanic would probably come to mind as a picture definition. No matter what task she was given or what obstacle she faced Winry always thought of how to do something differently. This can especially be said when it comes to her passion for building things. Now of course Winry's approach at innovation has had it's fair share of hits and misses, though Ed and Alphonse would often say they were mostly misses, like how anyone's endeavor would go. But with her hits she really does get it right.

And today, she was introducing Ed to her recent hit innovation…

“Huh!? A detachable moving automail arm?” Ed asked his girlfriend in surprise.

“Yep! It's been something I've worked on ever since you became a state Alchemist.” Winry replied proudly with a bright smile.

“That long? It must be a real passion project of yours.” Ed said.

“It sure is! Though I gotta say I didn't think it was possible, I guess even great inventions from a genius can get some improvement.” Winry boasted with a confident chuckle and flip of her hair to match.

“I think your humility could use the improvement more, pretty piston.” Ed said with a cheeky grin to which the other blonde stuck her tongue out at him.

“Whatever! Since you want to add in your two cents that makes you the perfect test subject.” Winry stated.

“Wait, what!? But why do I have to test it?! Why not Al?” Ed asked in shock.

“Because he's away on a trip, and I need to test this today. Plus you're the only one with an automail arm in front of me.” Winry explained.

“So that means if I put another sucker – I mean willing subject with an automail arm in front of you I'm off the hook?” Ed asked hopefully.

“Nice try, Elric.” Winry said with a grin as she shook her head in amusement.

“Damn it...” Ed groaned as he knew now there was no escaping his fate.

So the fullmetal alchemist allowed Winry to set him up for the testing of her new version of automail. He didn't dare add “improved” to it because the thing may end up gaining sentience and try to slaughter them all. Not like things like that haven't happened after all. Still even though he was on the wary side Ed couldn't deny that a modification like this would be very convenient if it worked. Here's hoping!

“Alrighty, just a circuit rewiring here, a bit of welding to secure the add-on there...” Winry trailed off as she tinkered with the new automail.

“So how exactly will I be able to move this thing while it's detached, Winry? You never did tell me when we started this.” Ed pointed out.

“Oh yeah! That's actually the easy part. But I want to finish this automail first before I move on to you, Ed.” Winry said, then after a final screw she stepped back a bit to look at her invention and smiled. “And done! Now onto phase two.”

Winry grabbed an off-white colored tarp and put it over the automail to cover it before Ed could see, then grabbed an oddly shaped object as a screwdriver from the table before walking over to her boyfriend.

“What, hey! Lemme see what it looks like. It's going to be attached to my body after all.” Ed protested, moving his head to try and get an angle to see through the tarp.

“Oh hush! You'll see it in a minute. First I have to fit this onto you and configure it, which will answer your question about how you can move the automail while it's detached.” Winry stated and showed the object to Ed.

It looked like one of the support plates Winry attaches before the joint part for his automail. Only this one had a gunmetal black finish and looked more...modern. Almost digitized in a way with the pattern and how sophisticated it looked. But there was a piece in the middle of the support plate, it looked like a plug in for a cable.

“Looks like a plug-in fancier version of my support plates.” Ed said as he looked at the device with great interest and curiosity.

“Exactly! And it's great that you pointed out the cable plug-in, because it plays a major role. Now we attach it in the same way as the regular support plate like so.” Winry said and placed the support plate on the mechanical stub, screwed it on securely and then walked back to the table with the covered automail. “And now for the grand unveiling!”

With a dramatic flare Winry removed the tarp, revealing a very gorgeous new automail arm. The finish was gunmetal black to match the new support plate and had light blue wiring that could be seen through the joint and muscle crevices. The arm sat flat on the palm of it's hand and showed a long type MC armored cable coming out from the center of the automail. It was so long that it was in a looped four inch thick pile next to the arm. And the plug at the end matched the plug-in for his newly attached support plate.

“Hot damn.” Ed said with wide eyes full of amazement.

“I knew you'd be impressed! Now for the first test.” Winry said and grabbed the cable, pulling it towards Ed and plugging it into the plug-in on the support plate. When she did Ed felt a slight surge go to his brain. Like his connection to the arm had been established. “Okay, now summon the automail to you.”

“Huh!? And how do I do that? Say 'automail, return'?” Ed asked with a joking expression.

As if on cue, the cable flexed like a whip and recoiled towards him and reeled the automail in as well. The mechanical arm then snapped onto the support plate with a loud, sort of satisfying click. And once again Ed felt another surge to his brain as the final connection to the automail was made. The sense of touch immediately came through also, like his arm fell asleep for a bit then got the feeling back.

“Whoa...” Ed spoke softly in awe which made Winry puff her chest out in pride and a smug smirk stretch across her face.

“And thus, Winry Rockbell makes yet another amazing piece of innovative automail! When I held the support plate up to you it was registering your voice as a sort of vocal print – so you can command it by saying 'automail' then give whatever order you have. And the cable compresses and coils inside it like veins when it's attached to you. It also has your weapon add-ons like the old one.” Winry explained.

“Damn, Winry...this is beyond amazing. This is a meta level badass!” Ed exclaimed happily as he jumped to his feet in excitement.

“Glad it meets your standards, babe.” Winry said with a smile.

“I can't wait to test this out. Oh! Maybe I'll use it for a match with Mustang. This will throw him for a real loop.” Ed said with a wicked chuckle as he flexed the fingers of his new arm.

“Actually, I have a different idea for you to test it.” Winry said with a certain tone in her voice. Like barely suppressed eagerness.

“Really? What is it?” Ed asked curiously.

Winry didn't answer, at least not vocally. She just took his arm and gave a grin that said 'come with me and you'll find out' then dragged him to their bedroom. The mechanic moved her boyfriend to sit on the bed and closed the door. When she turned back to face him Ed saw a very seductive look on Winry's face.

“One of the things I want to test and ensure works flawlessly is you being able to function the arm while it's detached from you. And also to see how you can feel while it’s detached.” Winry explained.

“Alright. So why did you bring me in here?” Ed asked.

Winry's grin surprisingly grew as she walked over to sit on a chair in the room. Then she raised her legs up, spread them wide and unzipped her hoodie to reveal a cute blond bush above her pussy. She then took her top off and undid her hair before leaning back against the chair.

“Because, I wanna see if you can finger me while I'm over here and you're over there using the new automail.” Winry replied seductively.

Ed was first surprised by the sudden turn of the mood, but it didn't take long for him to get aroused and return the seductive look with an “eager to please” smirk.

“Now Winny, you know I'm always happy to help you test your inventions. All you had to do was tell me.” Ed said in a husky tone. “Automail, detach.”

The prosthetic arm did as ordered and with a click and hiss of air pressure the automail detached itself from the support plate and landed on the ground on it's fingers. Ed experimented with flexing his fingers to see if he could perform the action while his arm was detached, and to his surprise he was able to. He even felt all of the natural physical sensations as if it was attached. So Ed worked his arm a bit more and got it to move – albeit somewhat awkwardly – towards Winry sitting in the chair. The arm moved up the leg of the chair, latched onto Winry's leg and stroked her thigh. She moaned at the feeling of the cold metal on her skin. It was a pleasurable sensation that made her wet. And Ed had the pleasurable feel of Winry's warm skin in his automail hand and it made him hard, prompting him to pull his dick out with his flesh hand and start to stroke himself. This made the blonde mechanic do the same by grabbing both of her breasts and started playing with them, pulling on the nipples and rubbing her tits against each other.

“Ooh, Ed...Pl-please. Finger my pussy...Ahh.” Winry moaned as she bucked her hips in a wanton motion and pulled down her short a bit to show off her pussy that was now glistening with moisture from her arousal.

In between grunts Ed nodded and moved his automail to Winry's exposed vagina. He first played with the bush of blonde hair above it, twirling the little curly hairs a bit before moving his metallic middle finger to the clit. Ed pressed on it hard and then gave it a firm flick which made Winry quake with pleasure and buck her hips up as high as she could in her position. She also pulled on her breasts more and brought one to her lips to lick it.

“G-God, you look awesome like this Winry. Your tits...bouncing in your hands...pussy all wet for me. Ugh, we should have tests like this for your inventions more often.” Ed said between grunts as he stroked himself a bit faster while fondling his balls in between strokes.

“Ahh! E-Ed...so hot for you. More, please...O-ooh.” Winry moaned out.

And who was Edward Elric to deny his beloved girlfriend? After playing with her clit a little bit more Ed moved the automail down to the folds of her pussy, stretching them open wide then closing them and doing it again to tease her. Winry never stopped bucking and squealed from the teasing treatment which made Ed grin in delight. He decided that he was done teasing her and went in for the kill. He moved the middle finger of his automail towards the hole of Winry's vagina and after a bit of prodding he shoved it inside. Winry threw her head back as she let out a strangled noise of surprise at the cold metal inserting into her and pleasure for having something inside her. The rush of new warmth around his automail finger made Ed even harder which made him stroke faster. He thrust his finger finger in and out for a while, then inserted his ring finger. With them both inside Ed made his automail twist and jerk at a medium pace which had Winry's eyes rolled into the back of her head with pleasure.

“Agh! Y-Yeah...that's it. You like that, Winny? Ya like...ahh! Having my new automail in your pussy? Bet you c-could...take the whole hand inside and love it.” Ed said in a dirty tone.

“Oh yes! Yes, yes Eddy! P-please shove in your hand! Pump into me! Oooh, a-ahh...!” Winry exclaimed in an erotic reply to her boyfriend.

Again – Ed was not one to deny someone he held so dear. So he pulled his fingers halfway out, waited for Winry to settle down a bit and without any warning shoved in all five fingers of his automail. Now with practically two thirds of his hand inside Winry's pussy Ed thrust in and out with reckless abandon. This really sent Winry off the edge and she screamed loudly in pleasure and bucked her hips to meet with the thrusts of the hand. Ed pulled and stroked hard on his dick as he watched his girlfriend go wild on his automail. He could even feel her juices dribble down his metallic hand. It was so hot, the musky scent of their growing lust was filling the room.

Finally...it all came to a head. Ed was the first to cum, shooting a thick load that leaked through his fingers. Then Winry came and squirted a heavy amount of her juices. So much so they rained down on the rest of Ed's arm and covered it in large droplets of pussy juices. The couple road out their respective orgasms for a while before they both calmed down, panting tiredly from their sexy fun session. Ed quietly commanded his automail to return and it slowly pulled out of Winry's pussy with a lewd pop and the cable reeled it back into his support plate. Ed fell back onto the bed and panted out his exhaustion. After some of the feeling came back in her legs Winry slowly got up from the chair and walked over towards Ed. She crawled onto the bed with him and took his cum covered hand to lick his fluids off it. The fullmetal alchemist slowly turned to look at his girlfriend and gave her a tired smile.

“Winry...you really outdid yourself this time.” Ed said. Winry stared at Ed while she suckled a cum covered finger then smiled at him.

“Thanks a lot, babe.” Winry replied happily.
