Work Text:
Mammon's mansion was HUGE, as expected given that he was the Sin of Greed, of course it would be huge. Also given that his normal size is much larger than you and the smallest size he can shrink down to is around your size (he still wants to be bigger and taller than all the other imps). It was a miracle that you had gotten this job, considering your rent was due in three weeks and your paycheck would clear before then.
Despite Mammon knowingly being stingy with money because he wants to hoard it all- he was paying a pretty penny to make sure whoever was cleaning his mansion wouldn't steal or mess things up. So the job ended up paying more than your previous job that you've worked at for three years! Nobody cared enough to reopen it after the owner died from not paying Greed’s infamous mafia, so you were out of a job. Good riddance to him though, he treated you like shit.
It was your third day here and you still got lost, having to either ask his other employees or a map that was kindly given to you from a butler. That same butler told you that Mammon originally wanted to hire only one cleaner after firing almost his entire staff before this, however convinced him that one “lowly” imp would not be able to fully clean his place to his standards. You were the last one needed to be fully staffed, mainly cleaning his bedroom. You were glad the guy convinced the Sin to hire more because just cleaning the bedroom took hours, he was a slob.
You were just finishing up making the bed exactly how he likes it when the butler who's been helping you around enters the room. You met Mammon on your first day, because he showed you very clearly how he likes his room. The butler's name was Bernard and he was older, having worked for Mammon for over ten years, but was always kind to you and the other staff, so you considered him a good friend.
“Mammon requests your presence in his office” That made your blood run cold- why does Mammon want me? Gulping, you made sure there were no wrinkles on the sheets before taking a deep breath and joining him.
“And no I do not know why. You'll learn very quickly that he doesn't say why until you are in the room” It was obvious that he was concerned for you, worry was present in his eyes since you heard that Mammon can be extremely intense and harsh to his workers. He was quite harsh to you on your first day, but that only was because he didn't want you to fuck up.
“I hope I'm not fired! I just started!” You exclaimed, really hoping that wasn't the case. You needed this job! Badly! Anxiety peaked as Bernard just patted your back in comfort as you walked through the hallways, soon arriving in front of the large doors that held his office behind it. Opening them, he waved you through and immediately you spotted Mammon with an expression you couldn't decipher sitting at his desk playing with a…fidget toy? Before you could even blink, the second you entered the room, Bernard shut the door. Well, you couldn't be too surprised, he probably knew the routine.
“Fuckin’ finally! There ya are mate, took ya long enough. Now sit” Slamming the toy down on the desk, he gestured to the empty seat in front of him. Taking another deep breath to calm yourself, you sat down in the plush chair and realized just how close you were to him. The chair was positioned just a few inches away, leaving not much space for legroom and you didn't dare to move it a centimeter.
“You're a fuckin’ eyesore ya know that? Looking at slutty in that outfit” Panic immediately started to rise, he thought you looked slutty? It was the same uniform every cleaning imp wore! Looking down, you suddenly felt exposed despite it adequately covering you. Long, blank pants, neon green button up with a black vest, and a dark green apron with a black border around it.
“I-I don't know what you mean sir! This is the standard uniform and I have not changed it in any way!” He may have been the King of Greed and your boss, but you weren't going to let him get away with calling you a slut. He very dramatically slammed his elbows down and brought a hand up to his chin as if to think about it before his expression quickly changed to realization.
“Hm, you're right! Then maybe we gotta take it off of ya, eh?” Ok, you couldn't be in denial any longer- he was definitely flirting with you. Face burning hot, you sputtered being rendered speechless, why was he flirting with you?
“You're even cuter when you don't know what to say. Lemme spell it out for ya since you're dense” He placed his hands on the wood and leaned forward, prompting you to lean forward as well to match his stance.
“Be my fucktoy and ya won't have to work” That made you short circuit. Be his fucktoy? You couldn't lie- some weird part of you thought he was incredibly attractive, but he was your boss. Your boss!
“B-but Sir Mammon…I…” You didn't want to outright deny him, but also didn't know if you could say yes.
“If yer wondering about pay, don't worry, I'll pay for everything” Ok- now that you couldn't possibly reject in your right mind. Just then, it occurred to you that you would be fucking a Sin. A Sin! Just working for him and being around him was enough, but being his fucktoy? Everyone knew about Asmodeus and Fizzaroli and you knew Fizz’s history as Mammon's star clown before he quit. You knew who Mammon was- but you needed this job. Should you really get tangled up with him like this? Being fully dependent on him would be horrible if you wanted to end the deal, but not everyday does Mammon want to fuck some random imp. You mulled it over as he impatiently tapped his foot and fingers on his desk, waiting for you to answer.
“Ok- fine. I will, bu-” Before you could tell him your boundaries, he picked you up right out of your seat like you weighed nothing and kissed you so roughly. Scrambling in his hold as he started moving, you pulled back to see a confused and angry Mammon staring back.
“But! I am allowed to say no when I don't want sex and I am free to leave here whenever I want. I will have money deposited in my account every month instead of relying on your cards for every purchase” The Sin grumbled as he thought about your wants. You still wanted to have some form of independence being in this situation after all, you would just reject the offer if he refused.
“Ya drive a hard bargain there, little one. But who am I to say no to that face” His smile was predatory, as he kicked open two large doors. It didn't take long to look around and see that you were back in his bedroom. Oh-so he wanted to start the deal immediately. Throwing you on the bed, you felt your heart start to beat faster as he stared down at you.
“W-wait! I just made this bed!” You weren't completely using that as an excuse to delay it, you just finished making it and it would be utterly ruined by the end!
“Don't worry about it mate, someone else can clean it up. I've waited long enough for ya” Without wasting anymore time, he leaned in and ripped your clothes off, leaving you just in your underwear. Face burning hot now, he got even closer and licked all the way from your belly up to your chest, making you shiver as you gripped the blanket underneath you. His smirk only made you shiver more as the sin finally got on the bed, settling his larger body to hang over you.
“Mmm…gotta taste more of ya” Deciding to rip off your bra and before you could scold him for doing so- he latched onto one of your breasts and sucked on your nipple, causing you to moan loudly.
“M-Mammon!” Squirming as you felt yourself becoming wet, you groaned as he finally pulled away with a ‘pop!’. Staring at him, he had that same predatory smirk as he looked down at you, before looking even further down. You watched him as he eyed your underwear and quickly ripped that off too.
“Hey! Stop destroying my clothes!” You yelled, immediately taken out of the moment as he ripped up both bra and underwear. The underwear you didn’t care much about since those came cheap in a pack, but the bra was expensive! Plus, how are you going to leave? Commando? In front of everyone else?
“Oi, shut up. I’ll buy you new ones” You were going to scoff and complain more when he dipped down and gave your pussy an experimental lick. All thoughts disappeared as your spine shivered, you took a huge breath as he dove in. The sin shoved his face in, tongue penetrating you in ways a dick never could. Moaning loudly, you gripped the sheets as he continued to eat you out, holding onto your thighs so you didn’t move around so much.
“Mammon! Fuck!” His tongue was so big, moving all around inside you and to make matters worse- or better- he started to suck on your clit. Not being able to feel the pressure coiling inside you, you blindly reached up and grabbed one of the oversized pillows and shoved it over your mouth, tightly gripping it as you screamed into it. That didn’t last long as it was ripped from your grasp. The pressure kept building in your stomach and you felt your orgasm wave through you as he only ate you out more.
“FUCK MAMMON!” You squirmed as you rode it out, breathing heavily as he finally stopped and eased his tongue out of you. You laid there catching your breath, feeling completely blissed out staring at the ceiling. All you could think about was just how good his cock would feel inside you, not regretting accepting the deal at all. You felt the bed shift around you and Mammon’s face came into view.
“I’m gonna take good care of ya, but I’m not done just yet”
