Words: 770+

Warnings: this fic doesn’t have smut in it (booorinnggg) but it does handle some adult themes so keep that in mind if you want to read this fic.

“Ed? Could you get my wrench from my room? I think I left it on my desk
when I fixed my radio the other day,” Winry yelled from her workshop when she
heard Ed’s mismatched steps getting closer.

“Am I your slave or something?” Ed grumbled for probably the 100^th
time since returning from the Promised Day. He didn’t actually hate work,
mostly protesting out of the habit, and Winry knew it.

“If I remember correctly, you asked me to marry you, so you’re in no
position to say anything like that!” She reminded him, and he had no other
choice but do what ordered.

When in Winry’s room, Ed didn’t find the wrench on the desk like she had
said he would, but he knew Winry wouldn’t give up until she got it in her hands.
That’s why he started opening the drawers, something he would never
dare to do in a normal situation, to see if she had accidentally dropped it
there. Winry usually kept them locked, but it seemed that this time she had
forgotten to lock them.

The wrench wasn’t in the two top drawers, but in the third one Ed found
something that drew his attention. It was his old automail, or rather, what was
left of it after the final battle against Father.

“Why would she…” Ed wondered briefly but set the automail on the desk
and took the magazines Winry kept under it into his hands. The first one was
nothing special, just Winry’s regular Automail Weekly magazine, and Ed probably
wouldn’t have paid attention to the second one either if something hadn’t
fallen from between it. It was a photo, and Ed quickly recognized himself in it.
This one had been taken on a really hot summer day when they had been swimming
in the nearby lake, and Winry hadn’t been able to resist taking a picture of
him when he had been walking on the beach in only his swimming shorts, his body
wet and tanned. She had promised to keep the picture away from Pinako’s eyes,
which was probably why it was between this chicks’ magazine.

… Or was it? When he took a closer look at the magazine, he realized it
had some… dare he say… interesting
articles in it. How to make sex more
enjoyable, how doing thing X in bed
changed our relationship… The pages that seemed to have been opened the
most included masturbation tips. Ed browsed the article fast, and the more he
read, the more his cheeks seemed to be burning. Did his girlfriend…

Then he noticed one more object in the same drawer where the automail
and the suspicious magazine had been. At first it seemed to be a tube of lotion,
but when he read the label, his suspicion got confirmed.

It was lubricant.

His girlfriend… his girlfriend was masturbating… with his automail… and
apparently she kept picturing him at the beach while doing it!

Ed felt his jaw dropping at this discovery and when he swept his nose
quickly, something red came out of it.

Oh god oh god oh god
this is too hot,
was the first thought that came into Ed’s mind, since he couldn’t help but
picture her in action… Then the evil side of him took over his brain and said
that he should totally use this information against her. Maybe she wouldn’t nag
to him about small things so much after that… or maybe he could…

Soon Ed returned to Winry’s workshop, giving her the wrench (which he
had found on the floor soon after having recovered from the shock caused by his
discovery) and holding something behind his back.

“Ed? What’s going on? You look kinda funny,” Winry asked curiously,
knowing he was hiding something from her.

He dropped the objects he had found in the drawer onto her workbench with
a smug expression on his face, and Winry’s eyes widened in horror.

“You weren’t… You weren’t supposed to know about this! Why did you check
the drawers anyway? You know you aren’t allowed to…!”

Ed was expecting a wrench to his head but apparently Winry was too
shocked to move.

“You had left them unlocked and I was simply looking for the wrench… and
happened to find this instead.”

“Ugh, fine, yes, laugh ahead… I masturbate with your old automail.” Winry admitted and buried her face into her hands in shame. 
Ed didn’t laugh, though. “It’s OK, Winry, it was just fun to make you sweat.
But now that I know about this kink of yours…”

“Yeah?” Winry asked, half worried, half curious.

“I think we should put this information to use.”

True to his words, that’s what they did.
