Work Text:
Things were changing in the Underground.
It hadn’t been quite so bad at first, when Greed had first been born. It had just been the three of them for a while, him, Lust, and Pride — and of course Father, but he had left Greed alone, for a while. He was usually busy with his own projects, and didn’t have much use for Greed or his shield. It meant Greed wasn’t allowed above ground much, which felt like pins being driven into his skin, the knowledge that there was so much up there to take — but he used to be able to live with it. There had been more freedom in the Underground then, at least. The homunculi could do as they pleased, entertain themselves without Father breathing down their collective necks, always demanding more.
Not anymore.
Greed stomped down a tunnel, simmering with annoyance as he followed the sound of dripping water. It was getting too crowded in the Underground for his liking, and he wanted some alone time. It shouldn’t be quite so hard to find a place to be left alone, considering the labyrinthine map of tunnels the homunculi called home, but privacy was a luxury they were rarely afforded. And to think, Father said he was working on a new sibling for them, like any of them needed that. He couldn’t wait until he was allowed to go back up, where the world was so much bigger, and there was so much to possess.
Until then, he could only visit the garden.
The garden was Lust’s personal project, one she rarely had time to attend to anymore, with the way their work had been picking up. No one was supposed to visit it without her permission - but when Greed wanted something, he wasn’t going to ask for it. And what he wanted was some fucking alone time, because if Pride lectured him one more time, Greed was going to snap.
The garden was in a cavern with a natural spring and no natural lighting. Instead, the flowers themselves, seeds made from Father’s alchemy and carefully tended to by Lust, glowed eerie red, the same color as the Philosopher’s Stone. They lit up the cavern around them, making the spring water that fed them look like blood. There were maybe 100 different varieties, lilies and roses and lots of other flowers Greed couldn’t even begin to name. He had tried to take some once, gone to all the trouble of digging a whole plant up, roots and all, but it had withered up the second he crossed the threshold of the cavern. Not to mention what Lust had done when she found out. So now, Greed just snuck in here when he wanted to be alone.
“You aren’t supposed to be here.”
Greed smirked when he heard the familiar, whiny voice, though he didn’t look around for the source of it. He hadn’t seen the kid when he came down here, which meant they were hiding. They only hid when they wanted to be looked for, and Greed didn’t want to give them the satisfaction.
“Neither are you, the last time I checked.”
There was an annoyed hiss and a rustling of plants, and in the low red light Greed saw a flash of coiling scales.
“Father said I’m not supposed to talk to you anymore,” came the next complaint, and Greed almost laughed at that.
“No one’s making you talk to me, kid.”
Another hiss, and the snake was coiling near his feet now, as thick around as his arm, many feet long with sharp fangs that it bared like it might bite him. Now Greed couldn’t help chuckling at this display, because it was just like Envy to think they were being intimidating.
The reason Envy wasn’t supposed to talk to Greed anymore is because somehow, every time they spoke they ended up fighting. The youngest of the homunculi was unstable after all, so unstable Father had almost decided they were a failed creation, almost melted them back down — but, as it turned out, even a disappointing experiment can produce useful results, which was what Father had said when Envy, ugly and monstrous, had successfully changed shape for the first time, into a perfect mirror image of Father. Envy could barely control their power at first, shifting wildly, matching anyone they looked at, but after a few decades their abilities were under control now. Their personality, though, was decidedly not.
“I hate you,” hissed the snake bitterly, rearing up as it spoke in Envy’s voice. “I’m not a fucking kid.”
Greed laughed again, and decided to make a show of turning away from Envy, ignoring them to look at the flowers nearest him, a bush of glowing roses. There was a crackle behind Greed, and he knew Envy had changed shape again, and he had a guess as to what form they had taken.
“Why don’t you just leave?” snarled the younger homunculus — and glancing over his shoulder Greed confirmed that Envy was indeed in their favorite form, the one they had come up with themself, with androgynous features and long green hair. Greed liked that form too, liked how unique it was and thought it suited Envy — but he wasn’t about to tell them that.
“The garden is big enough for the both of us, last I checked.” Not that Greed particularly felt like sharing, but nothing set Envy off like being dismissed.
“I was here first!”
Greed laughed at that too, at the way Envy sounded like a child. “Don’t cry about it,” he teased, emphasizing the word that he knew would embarrass their younger sibling the most. They had done a lot of uncontrollable weeping the first few years into their existence, along with wild outbursts of rage, and fits of agitated laughter, all of which had earned Father’s scorn. Greed knew the crying had embarrassed the creature the most though; it was obvious, and made it an easy target when he wanted to bully Envy.
Sure enough, they bristled immediately, face twisted into an ugly snarl as they petulantly stomped their foot, the slight rumble of the heavy motion an implied threat of their true size. Greed snickered. Their true form was the only intimidating thing about Envy. “What?” he taunted. “Gonna show me your real face, ugly? Careful, if you destroy the garden you’ll be the one punished by our sister.”
“Don’t fucking call me ugly!” Envy lunged at Greed, left arm crackling into a sword in a flash of red light, roaring like they were using their true form’s monstrous lungs. Of course, a sword could do nothing to Greed, and he reminded Envy of that by catching the blade with one black hand, arm covered in the Ultimate Shield, before kicking their stomach as hard as he could, knocking them back a few feet.
“Calm down, crybaby,” Greed teased, trying to rile Envy up more. Envy was a shitty fighter, something Greed had learned from the little monster’s penchant for trying to fight him. All they knew how to do, besides shapeshift of course, was throw their weight around. It was fine against humans, Greed supposed, but Envy had never won a single fight against Greed, and the younger homunculus had managed to start a lot of fights with Greed in their relatively short time being alive.
Maybe they liked being defeated, thought Greed wryly.
Envy wasted no time in lunging again, throwing a few blows Greed dodged easily. Next they tried turning their hand in a snake, which was kind of a neat trick because it gave them more range - but that also meant Greed could simply catch it with his shielded hand, his indestructible claws making short work of the snake-arm, slicing it off as Envy shrieked in pain and lept away, clutching their arm as the alchemy crackled and began to regrow.
“That’s not fair!” Envy whined as their arm developed, which was patently ridiculous, because they had just turned their arm into a fucking snake.
“Gonna cry about?” Greed teased. Stupid little Envy, they took the bait every time, throwing themselves at Greed again as soon as their arm had finished healing. This time Greed ducked low as Envy charged at them, grabbing their arm to use their own momentum against them. Envy might weigh much more than Greed, but with the way they rushed blindly at him it wasn’t hard to redirect their speed against them, tossing them over his back and headfirst into a dense patch of glowing red flowers that Greed couldn’t recognize. Pollen from the flowers exploded up around where Envy fell into them, little glowing mushroom clouds of plant destruction that momentarily obscured where their sibling had landed. Then Envy reared up, luminescent pollen glittering all over them, which would have been pretty if their face weren’t twisted in ugly rage. They shrieked again, voice like a hundred wild animals all wailing at once, lunging at Greed again, fingers green and clawed like a monster.
They were trying to look scary, but Greed could tell Envy was frustrated, on the verge of giving up. So he again dodged easily, instead directing a kick to Envy’s stomach. The momentum of Envy’s own charge made the kick hit harder, and that was all it took to knock them to the ground, another cloud of powder bursting off them on impact as they landed with an earthshaking thud, all flailing limbs and glowing powder. Satisfied that Envy would stay down for at least a minute, Greed took a second to inspect the bits of pollen that had gotten on him when Envy charged. It smelled sweet, not in the way the roses or lillies did though, sweet in a way Greed couldn’t place, but didn’t feel like much when he rubbed it between his fingers.
“I hate you,” hissed Envy, still on the ground, clearly pouting now. They were glaring up at Greed as they fruitlessly tried to wipe the pollen off of their face. “You’re not even that good at fighting, I just got this gross shit in my eyes.”
“Sure, sure. Don’t be embarrassed just cause you lost, kid,” teased Greed, knowing it would just embarrass the younger homunculus more, and was gratified when they scowled at him in response. They didn’t get up though, not even to storm off in a pout. Envy just stayed lying there, scowling up at Greed — and were they trembling?
“Is something wrong?” he asked before he could think about it, confused by how Envy was acting.
“I feel- weird.” Envy was still scowling, but they propped themselves up on an elbow, looking down at their own shivering body. “Something- something’s weird.”
“You gotta be more specific,” said Greed, eyes following Envy’s own, running along the harsh angles of Envy’s little waist, their bare thighs, still glittering with pollen. They had certainly made this form of theirs alluring, small enough that it made Greed want to manhandle them, squeeze the white flesh of their thighs as—
Greed blinked, pulling himself out of his reverie. Since when did he think things like that about Envy? And what’s more, Envy was still acting strange, visibly quivering and shifting restlessly on the ground. They touched a hand to their abdomen, a confused look on their face.
“Feel… weird,” was all Envy seemed to manage, and Greed frowned, dropping to his knees next to Envy. If something was wrong with them, Greed would surely be blamed, but what could he have done to them? They didn’t look hurt, but what —
Envy ran their hand delicately over their bare stomach, shivering under their own touch and moaning in a way that stopped Greed’s thinking for a second, breathless and undeniably lewd.
What. What the fuck.
Envy moaned again, stroking their shivering abs, looking confused and aroused as they touched themself, and the sweet smell of pollen was strong around them. The pollen, that had to be it, somehow. It was Lust’s garden after all, so when Envy had been covered in it, maybe it was doing… something. A little of the pollen had gotten on Greed too, and he supposed that would also explain the way he was suddenly transfixed by the other homunculus. Envy was so sensitive to just their own touch, how would they respond if Greed grabbed them, touched them, bit them…
Greed tried to focus. “Envy, I think… the pollen…”
“Touch me,” interrupted Envy suddenly, a breathy, urgent demand, looking up at Greed with wide eyes. Fuck, they almost looked innocent like that, doe-eyed and trembling, and Greed didn’t know if it was the pollen or his own nature that he felt the burning need to take them. “I- I- fuck, need you to touch me, Greed —”
No one could ever accuse Greed of having good impulse control, especially not when a pretty little thing was in front of him, begging for it. He groaned, grabbing Envy’s face to pull him into a fierce kiss, his other hand grabbing at their waist as he climbed on top of them. Envy, for their part, melted into the kiss, not really kissing back, but opening their mouth to be ravaged, urging Greed closer with their grasping hands. What a sweet thing they were being, pliant and wanting, instead of their usual behavior. And so sensitive — they were moaning hotly into Greed’s mouth as he ran his tongue along Envy’s sharp teeth. With the amount of pollen that was on them, Envy must be dying for it — but Greed wasn’t sure if they even knew what they wanted, or had the equipment for it. Greed had never thought about Envy’s genitalia before, never had a reason too, but now it felt like all he could think about.
With that thought he pulled back from the kiss, watching the homunculus under him squirm as Greed’s hands kept grabbing at them, one running over Envy’s chest, the other grabbing at their thigh. “This what you want, baby?” he growled, hoping they understood. “You want me to keep going?”
Envy moaned and squirmed, nodding furiously and trying to pull Greed closer, but Greed held firm.
“Do you have — you know? It’s the pollen, I think, Lust’s pollen... So, you need to change.”
Envy frowned, normally slitted pupils blown wide, expression strange and unreadable. “You- what do you want then? I can be whatever you want, whoever you want, just —”
And then they were changing under him, almost too fast to keep up with, manic as they shifted from a pretty red haired woman, a handsome young man, a blonde woman with breasts like Lust, a petite short haired woman — shifting, shifting, shifting, making Greed feel dizzy.
“Just- just fuck me Greed, I’ll be anyone you want, please —”
Greed growled, shoving Envy down maybe too hard. “Stop that, freak!” he snapped, unexpectedly annoyed at Envy’s offer. Why would he want to pretend to have something he didn’t, pretend Envy was anyone but themself? “That’s not what I fucking meant! Stick with your regular form, dammit!”
Envy hesitated, temporarily caught between two forms in a way that made them look stranger than usual, then they obeyed, dark green hair fanning out under them as they went back to their preferred form — though they were naked now and fuck, that was nice. They were all cold pale skin and lean muscle, though sure enough, between their legs was nothing but featureless skin, like a child’s doll. Greed grunted, spreading Envy’s thighs and palming over where their genitalia would be.
“There we go, sexy,” he growled, and Envy squirmed, whining softly as Greed squeezed their thigh so hard it would bruise a human, massaging their featureless groin. “You just need to add something to fuck with. Unless you don’t want to get any relief.”
Though that wouldn’t be all bad for Greed, he supposed, keeping Envy needy and mindless as Greed used him to get off. He could rub between their muscled thighs, shove his cock down their throat, cover them in come over and over as Envy cried and begged for pleasure they couldn’t have.
Fuck, Greed was hard.
Greed was no stranger to his carnal impulses, no stranger to sex, but he was harder than he had ever been before, throbbing painfully in the confinement of his leather pants. This definitely wasn’t natural, and he could only imagine how Envy felt, covered in the pollen like they were. It was no wonder they were looking up at him like they could barely think, gasping and quivering.
Luckily, before Greed could get impatient there was an alchemical crackle under his hand as the flesh there shifted — and Envy’s head rolled back, moaning loud as Greed’s hand now pressed against a dripping cunt.
“Oh,” groaned Greed, running his thick fingers along the dripping folds of Envy’s hairless labia, wondering if this was the first time their little sibling had worn something like this, at least in this form of theirs. “Oh that’s good, baby. What a pretty little cunt.”
Greed’s thumb found the swollen nub of Envy’s clit, rubbing over it softly, and the effect was immediate. Envy wailed, writhing until Greed pinned a hand to their chest, spreading their legs for more. What a little slut, spreading their legs for Greed. If only they were like this all the time. They took two of Greed’s thick fingers easily, squeezing hard around them as Envy moaned.
“Yeah, fuck, yeah,” Greed was babbling uselessly, feeling something close to drunk, though of course Greed had been drunk, and it wasn’t like this. “You like that? You like being filled up? Oh yeah, take it baby, you’re fucking dripping, fuck —”
Envy was falling apart for Greed so easily, arms crossed over their eyes as they squirmed in the dirt, wailing at every brush of their clit. How much of this was the pollen, Greed wondered, and how much was the homunculi’s lack of experience? It seemed like no one had touched them this way, maybe not even themself, poor little thing. Maybe they had wanted this all along, needed it, to be thrown down and fucked like an animal. Envy kept such a pretty form after all, wore such skimpy clothes, but still no one had shown them how to feel pleasure like they deserved. Well, Greed would fix that.
“Yeah, fuck, come for me, baby,” he grunted, curling his fingers insistently against a spot that made Envy shriek louder, the noise echoing eeriely in the cavern around them, hips thrusting up against Greed’s hand. He was sure Envy was already close, with the way they throbbed and clenched around him, and Greed wanted Envy’s first ever orgasm as badly as he wanted anything. To feel it, see it, taste it —
Greed shuffled down, urgently pressing his tongue to Envy’s clit, moaning as their hands flew into his hair, gripping hard as Envy made a noise like a wildcat, hips thrusting up for more. Envy’s pussy tasted good, though different than human women, not that Greed really cared. He just licked in deeper, tongue brushing his own fingers as he worked at their clit. Envy was cacophonous as they squirmed and pulled at Greed’s hair, getting louder and louder until they gave a shriek and seized under Greed violently, feet slamming into the ground so hard the earth beneath them shook. They squeezed so tight around Greed’s fingers he wondered that they didn’t break, though it would have been worth it even if they had. When Envy finally went lax, releasing the painful grip in Greed’s hair, Greed pulled back with a primal growl. Greed needed to be inside of Envy, needed to feel them come like that around his cock.
Greed pulled back to tug open his belt, shoving his pants down just enough to free his cock, feeling half mad with desperation. Envy was too tempting like this, spread out for the taking for Greed, he couldn’t resist. Grabbing Envy’s hips to line them up, Greed shoved inside with one long thrust, Envy’s cries echoing and mingling with his own punched out moan. They were so tight, still clenching from their orgasm, wet and throbbing around Greed — and Greed was sure sex had never felt this good before. Under him Envy was whining, arms wrapping around Greed and clinging to him with their unnatural strength — and oh, now that Greed could see Envy’s face again, he could see tears glittering in their pretty eyes, wetting their eyelashes as Envy wrapped around him. Fuck, Greed wanted to make Envy cry, cry overwhelmed tears of pleasure as they came on his cock, make them come till they were fucking sobbing.
Snarling, Greed caught Envy’s mouth in another claiming kiss as he immediately set a brutal pace, fucking into Envy with wild abandon. The noise Envy made was muffled by the force of Greed’s kiss, and it was so fucking good, Envy moaning into his mouth as he pounded into them. They seemed to be taking to the kissing now, pressing to him as close as they could, urging for more with lips and tongue. Greed was also vaguely aware that Envy’s claws were doing real damage to his jacket where they were clinging to him, but he really didn’t give a shit. He didn’t even care about the way Envy kept tearing into his skin with those talons, small pricks of pain followed by his body’s alchemical healing response just fueling his mad desire. He just needed more, more, more.
Greed broke the kiss to change position, just a bit, sitting up so he could reposition Envy, grabbing their legs and shoving their knees towards their chest, letting their ankles rest on his shoulders as he nearly folded them in half. The other homunculus was surely strong enough — or perhaps more accurately, big enough, even packed into this tiny form — that Greed shouldn’t actually be able to maneuver Envy so easily, but he supposed they must be letting him. It was intoxicating, how pliant Envy was being, how obedient.
A wild animal tamed.
“Fuck, so good,” gasped Greed. He could thrust in deeper from this position, and harder too. He could also watch Envy fall apart, their hands scratching at the ground, eyes glittering with unshed tears, mouth hanging open, as they took his cock over and over. It was so much, too much, Greed felt out of control. “This pussy is so fucking good, baby, so fucking good for me. You made it just for me, didn’t you? You made it for me to fuck, that means it’s mine, my pussy, all mine —”
Greed really had no idea what he was saying at this point, but it was okay because he doubted Envy was really listening, what with the way they were crying out with every thrust, head thrown back in mindless pleasure. His thrusts were growing more and more erratic with every push, and distantly Greed realized he was close to his own orgasm, but even his own pleasure was second to his need to claim Envy, take them, keep them. He couldn’t stop touching the pale skin stretched out before him, tugging on Envy’s hard little nipples, stroking their toned stomach, petting at their hairless calves and thighs. He wanted Envy to be his, all his, his touch as greedy as the rest of him. The glittering pollen stained Greed’s large hands as he touched the beautiful creature, but he was far past thinking about what was causing all this, or of any consequences.
“Gonna make you mine,” he grunted, so close, so close, and when his hand drifted between Envy’s legs to rub their clit again, Envy gasped and squeezed like a vice around Greed’s cock. “Gonna- fuck —”
Greed’s orgasm hit him all at once, overtaking him sudden and hard, like a punch in the gut. Envy squeezed around him inhumanly tight as he spilled into them, rolling their hips with the throbs of Greed’s cock eagerly as they took his cum — and this meant Envy was his now, it had to. Envy belonged to him, to only him. No one else had ever known Envy this way, and no one else would, not if Greed had any say in it. He leaned down to take another kiss from Envy, fangs clacking together messily as Greed collapsed on top of them.
He was still hard, and Envy was squeezing him so tight Greed didn’t think he could pull out of them if he wanted to. That was okay though, because his avarice was not nearly sated either. He kept kissing them, touching anywhere he could reach, hard muscles under soft, cold skin. He found their clit again with large, clumsy fingers, swallowing the little shrieking moan Envy made at the contact.
“Fuck, baby,” moaned Greed when he broke the kiss, rocking his hips shallowly into Envy’s clenching little hole as he kept rubbing their clit. He kissed down their chin to their throat, scratching his fangs along the delicate skin there. “Can’t get enough of you.”
Envy burst out a laugh at that, the noise of it as ugly and unkind as ever, but it turned into a throaty moan as their hips kept rutting together. It just made Greed want them more. He wanted to keep this cruel little monster forever, his own little toy to keep and fuck. Greed bit into the crook of their neck as he thrust in harder, drawing another sharp cry out of Envy, wishing the mark wouldn’t heal itself when he drew away. “Come for me again, doll. I wanna make you come again.”
It didn’t take much to work another orgasm out of them, oversensitive as they doubtless were, just a few more good rubs on their clit before their entire body spasmed and constricted, their entire body arching up under him as they squeezed around him so tight it almost hurt. The savage orgasm seemed to last forever, until just as suddenly Envy went limp under them, gasping for breath raggedly. Greed moaned, having to bite his own lip to keep from orgasming at the way Envy clenched around them. He didn’t yet know when the pollen would wear off, if his mania would end before Envy’s, and he needed to make it last.
Under him, Envy was a glorious sight. Their eyes were wide and hazy, mouth hanging open, green hair fanned around them in a beautiful mess. Impulsively Greed wrapped his free hand around their pale throat, not to choke, but simply to see how it fit in his fingers. Envy arched up into his touch, and he could feel the delicate sinews of their throat vibrate as they gasped and moaned.
“M-more,” whined Envy, bratty and desperate all at once, rocking their hips up to meet Greed’s, clenching around him with intent. “More, Greed—”
Greed cut them off with a little squeeze at their throat, and a particularly sharp thrust of his hips that combined made the homunculus yelp, and throb wantonly around Greed’s cock. Fine, if they wanted more, Greed would give it to them. He set a brutal pace, grabbing Envy’s hips to steady his thrusts as Greed held the little monster down by their throat, fucking them as hard as he could.
Tears were glittering in Envy’s eyes still, as they screamed and moaned under them, threatening to fall. Always a crybaby, that was their little sibling, but it had been an annoyance in the past, when Envy cried. It certainly had never driven Greed mad with lust before — but this was his sister’s garden after all.
“Yes, cry for me, doll,” he encouraged, his second orgasm approaching fast with the pace he had set. “I’m gonna ruin you, gonna fuck you so good you cry- Fuck, yes, you’re all mine, mine, mine—”
He shifted the angle of his hips to one that made Envy convulse, tears leaking from the eyes as they screamed, squeezing tight around Greed’s cock. He still managed a few more hard thrusts before Envy was coming again, writhing so hard that the ground shook under them, sobbing as they came with their clitoris untouched this time, still letting themself be held somewhat in place by Greed’s hand on their neck. The sight alone could have driven Greed over the edge in a moment, to say nothing of the feel of it, and he gave his own raw shout as he came so hard he felt like he might black out. He came too to the feel of wetness on his hand, the one that was still circling Envy’s throat. And as he forced his eyes to refocus, he could see that his lttle toy’s tears were flowing freely now from their unfocused eyes, dripping down to their chin and neck, and onto Greed. They hardly painted a picture of sorrow; Greed also recognized the echoes of one of Envy’s wicked grins, saw it in the way their mouth twitched upwards as they gasped in breath.
Lovely.
Greed leaned down, mindless of everything but the desire to taste Envy’s tears, licking at their cheek in what felt to Greed like some strange and primal show of possession — even Envy’s tears belonged to him. Envy made a half-hearted noise of disgust and wriggled under him as he did it, but made no move to push him away, seeming content at least for the moment to stay joined like this, with Greed’s hand around their neck and his mouth on their porcelain-cold skin.
“Let me keep you,” murmured Greed, against their cheek, moving the hand at their throat so it could be replaced with his mouth, kissing and sucking at their sensitive skin, reveling in the way he could make them tremble under him. “Let me keep you, I promise I’ll be good to you, babydoll, don’t you want me to keep you? Make you feel so good, just let me keep you…”
“Idiot,” wheezed Envy, tugging at the shreds of Greed’s jacket and shirt, ripping what remained of them off as Greed nipped at their throat. He was, remarkably, still fully erect inside of Envy, but the burning need was not so urgent now, leaving Greed’s own rapacity to take center stage.
“C’mon, doll,” he urged senselessly between bites and kisses, one hand in Envy’s hair, the other at their waist. “Promise I’ll treat you so good, baby, so good. Doesn’t it feel good, baby? Just let me keep you, I’ll take good care of you, take good care of all my things—”
Envy hissed, and then suddenly Greed tumbling backwards, because Envy had shoved him back in a fluid but harsh movement. Greed yelped in surprise as his back slammed hard on the ground, but he hardly had time to feel bereft at no longer being inside the younger homunculus before Envy was climbing on top of him, straddling his hips with graceless zeal. They wasted no time in grinding down, rubbing their wet cunt along the length of his erection, making the both of them moan loudly in the emptiness of the cavern.
“Fucking hate you,” Envy gasped even as they braced their hands against Greed’s chest, hips working eagerly, body on full display for Greed as they tipped their head back in pleasure. “Oh fuck… Don’t… don’t belong to you.”
That, of all things, shouldn’t have excited Greed more, but oh, there was something delicious about being told he couldn’t have what he wanted. It was a chase — because Greed would always take what was his, no matter what.
“C’mon,” he wheedled, hands stroking the expanse of Envy’s chest and thighs, touching wherever his greedy hands could reach as Envy grabbed the base of his cock, arching their back as they guided him back inside them. “You like it, you already like being mine, fuck, Envy —”
Greed broke off with a loud moan as Envy rocked their hips forward, hitting a spot inside them that made them whine and shiver with pleasure. The pace they set after that was as desperate as it was brutal, leaving both of the homunculi crying out breathlessly. Greed tried to match it, rocking his hips up to meet Envy’s, but mostly let them take what they needed, content enough to watch them writhe atop him, knees digging heavily into the dirt on either side of Greed. Envy was beautiful in their savage ecstasy, hair a wild snarl of green tickling their spread thighs, the stretch of which led to their gorgeous cunt, wet and swollen and stretched around him. It was so easy to run his hand along those white thighs and until he was again touching the soft folds of their labia, feeling where he was inside them. It was hard to rub their clit precisely with how desperately Envy was moving, but luckily they were so sensitive and swollen he didn’t have to do much, just press his thumb down and let Envy keep doing the work. They made a high pitched sobbing noise as they came, hips slamming down so hard against Greed’s it hurt — and Greed came again, without even realizing he had been close, spilling helplessly inside Envy’s throbbing cunt.
“See,” Greed managed to gasp, overwhelmed with sex and pain and pleasure and beauty. “You’re mine, mine, baby please —”
In any other state he would never beg for what he wanted — but Greed was most definitely not in his right mind. He couldn’t be, not with how much he wanted to kiss Envy right now. Surely, he was going insane.
Envy moaned and writhed over them, hands falling to Greed’s chest, so heavy that Greed called his Ultimate Shield to his chest, so Envy could rest their weight there without injuring him mid-coitus. Their green hair fell around Greed in a curtain as they leaned forward, cracking teary eyes open as they attempted to steady themself.
“Even… Even if I was,” they rasped out, voice hoarser than usual from all its shrieking. “Even if I was yours, you can’t keep me, you won’t.”
Greed grunted, not fully comprehending their words in his pleasurable haze. It sounded like nonsense. Greed, not keep something? Envy must have understood that though, because they sneered at him as they leaned closer, so close, so heavy on Greed’s armored chest.
“Can’t keep me,” Envy taunted, voice low, like it was a secret. “You know I’d be too jealous for you.”
Greed growled, and their lips met in a kiss that felt raw and brutal all at once, and Greed clung to Envy, wrapped his arms around them, trying to urge their oppressive weight to stay atop him, to envelope him entirely. Envy moaned, clearly pleased with themself, a terrible monster that Greed wanted nothing more than to call his own. He would keep them, he decided, no matter what Envy said. He loved proving people wrong, after all.
Envy moaned, hips twitching, still not satisfied, and Greed grinned into the kiss. It didn’t matter that this had started by accident, that they were fucking on the soft earth of the garden, that once they were found out they were certainly going to be in trouble. All that mattered was that Envy belonged to him — and Greed took good fucking care of his possessions.
(The two homunculi were of course found, eventually, and did get punished, for ‘rutting in the dirt like animals,’ as Father had said. Father also ordered that the garden be burned down, and personally oversaw it, watching with cold eyes until it was nothing but smoldering ashes.)
