Chapter 1: Day One: Masturbation - Greed

Chapter Text

This body was new.

Every single cell, from the hairs on his arms to the marrow in his bones, was unfamiliar. He felt as though he knew how things should have felt, because there was a strange sense of deja vu that hovered over every moment of being alive so far, but then it didn’t.

When he touched something leather he was sure he loved the texture of, it shent a shiver up his spine, and he promptly dropped it. He learned quickly about this Xingese prince’s preferences; loose fabrics, smooth silks. That was fine. This fucked up little family he’d been born into ran the entire military from the shadows - Wrath was the Fuhrer, for God’s sake. He could be spared the change for some expensive clothes. He could only imagine how he would feel about eating later.

It was while he was changing that he recognized for the first time that something else entirely was different about this body. He had some scattered knowledge of things inherited from the previous Greed, and he was pretty aware of what sex was - of how he knew to do it. He was pretty damn sure the equipment this body had did not match up with that muscle memory. It was obvious the moment he noticed the scars just below his pecks - from there, he processed quickly the way his crotch felt in his boxers. He froze for a split second, feeling a little… mixed, about the change.

Greed could not deny that he found his new features pretty damn appealing. The prince was lean, tall enough he could almost be called lanky, but his muscles were well defined. His face was youthful and handsome, his hair very well taken care of. If he were in his old body, he was sure he wouldn’t say no to this finer thing in a million years.

But, well, it was his body now.

That meant he could have access to it whenever he wanted, and that was enough to even out the deal for him. Hell, just thinking about it was making the damn thing tighten around nothing - that was going to take a little getting used to. For now, he would just have to try not to think about it. He had other things to do at the moment.

Greed went about the rest of the night and early morning trying his best to do his job. He was a bit annoyed at how difficult it was to do, if he was being honest; none of the rest of his siblings seemed to have an issue with it. For him, though, if he didn’t want to do something, it might as well have been pulling teeth.

By midday, though, he finally found himself alone - no Wrath or Pride staring at him every moment like they expected him to betray them. Maybe they were off doing whatever their fake jobs were in order to maintain their human appearance - Greed didn’t have it in him to care. He just sought out the nearest reasonably private place he could find, because if he had to wait a second longer for what he wanted he was going to explode.

He hid around a corner in the tunnels underneath Central, hurriedly unbuttoning and pushing down his pants. He was shocked by the thrill that ran through his body as his fingers brushed against the wet skin of his cunt, the shiver that ran up his spine as it met the cool air.

Greed cursed quietly to himself as he looked down, a bit surprised to find how aroused he was. Somehow, he’d missed how wet he’d become between his legs - he supposed that explained the aching need he’d felt steadily building the more he thought about what the prince’s body would feel like.

He felt like he probably wasn’t a selfish lover - he couldn’t imagine sex not feeling good without the other party getting off, or as close as they could get to it. Greed knew his way around a pussy, he could be reasonably sure; the knowledge was ingrained in his head from whatever horny lifestyle he’d kept up in his previous life. It made sense. He wanted it all.

Just thinking about it made his cunt clench around nothing, and Greed worried his lower lip between sharp teeth. Okay. This could be fun. Maybe he wasn’t so skeptical about the pussy anymore - maybe he could even figure out how much carbon it would take to make himself a cock, keep the pussy as an option for jerking off. He’d think about it later. He had a more immediate desire right now.

To the Avaricious, that might as well have been a need.

He dipped two fingers against his folds, rubbing up and down the sides a moment to test the waters before rubbing against his clit. He leaned his head against the wall and bit his lip to muffle a moan. He focused the area around it a moment before slipping his fingers closer to his entrance. 

One dipped in, and fuck, he barely had to move before he felt ready for a second. So the prince was a greedy little bastard too, huh? Greed imagined the faces this kind of pleasure could get from him, and he bucked into his fingers a little.

He established a steady, learned pace of thrusting his fingers against a spot that nearly made him cry out the first time he felt it for himself, and pressed the palm of his hand into his clit. Greed couldn’t help the moan that left him as the steady, heated coil of pleasure in his core suddenly burst; he hadn’t expected to cum this hard or this quickly, and it left him a little overwhelmed.

This, he decided, would stay a permanent option.
