"MC," started Lucifer. Then sighing, he closed his eyes.
Lucifer was seated behind his desk, his red tipped fingers resting at both temples while he schooled his expression into something approaching patience, smoothing out that ever present frown between his brows.
"Why did I have an interesting phone call from the manager of the First Devildom Bank today?" he finally asked.
"Weeeeell . . ."
MC stood in front of Lucifer's desk, a slightly sheepish expression on their face. They had their hands in the pockets of their RAD uniform and were scuffing one foot back and forth across the ground in studied nonchalance.
"It's probably about my safe deposit box," they replied with a hopeful grin.
And in one sense, MC was right. It was about their safe deposit box. Sort of. Mostly.
****
earlier that same day
MC signed into the bank register confirming their request to access their safe deposit box. Mammon's eyes had started to glow with a hazy golden light the moment they'd both entered the bank.
"Mmmm," the Avatar of Greed took a deep breath. "Yer can just smell it can't ya? The money, the desperation. I swear my hands are tinglin'."
And indeed it seemed they were. As he looked around, Mammon was unconsciously rubbing his palms against his thighs, grinning with delight.
When the clerk showed them into the secure room and left to fetch the safe deposit box Mammon turned to MC. As he looked at MC over the top of his glasses, MC caught their breath at his expression. Feral, hungry, insatiable, greedy.
Mammon saw what he wanted and saw no reason not to take it. His Infernal power was driving him now. Stalking forward, he looked like a predator who'd just spotted his ideal prey. MC took a step back till they hit the wall and found they were caged inside Mammon's arms.
His hands on the wall on either side of MC's head, Mammon lent forward, his nose next to their neck breathing deeply, a puff of warm breath hitting MC's skin, setting all their senses on fire. "Ya smell amazin', yer know that right? You, in this place, just amazin'."
Nibbling lightly down their neck to their collarbone he said, "There's somethin' about the boxes especially. Now that's real treasure. There could be anything in 'em, anything at all - like Kinder Surprise for grown ups."
Catching MC in a hungry kiss he devoured their lips with all the power of his greed, his tongue invading their warm, wet mouth, tangling with MC's own.
MC pulled at Mammon's shirtfront, sliding their hands inside and over his firm chest, returning the kiss with the same fervor. Tasting him, wanting him, pressing against his firm body in a wanton display of need.
Mammon's lips curved in a grin, his fangs grazing against the side of MC's jaw as he kissed along, nibbling their ear and giving a low chuckle at MC's delighted moan.
Mammon grabbed for MC, lifting them as MC wrapped their legs around Mammon's waist. MC could feel his urgent hardness pressed against them and they couldn't help but flex their hips, grinding on him.
There was a pop, pop, pop as Mammon pulled on MC's shirt, buttons flying off in every direction as he buried his face in their chest, kissing, sucking, biting, leaving blooming red marks in his wake.
There was a loud clang as the clerk dropped the box in surprise.
"I say!" came the indignant cry. "This is a reputable establishment, my Lord. We can't be having with that kind of thing in here!"
Mammon sighed, resting his forehead against MC's. "Yer don't really need to get into yer safety box today right?"
MC agreed, their expression heated, eyes fevered. "Take me home right this instant," they ordered him.
Grinning wickedly, Mammon kissed them again. "That's my human."

After receiving a considerable lecture from Lucifer, MC was about to leave the study. It was Mammon's turn next, hopefully his punishment wouldn't be too severe.
As they opened the study door Lucifer asked one last question. "What is actually in your safe deposit box? Would you prefer to use a private safe in the House?"
MC peeked back over their shoulder, their answering grin as wicked as any demon.
"Absolutely nothing. It's totally empty. I only got it because it drives Mammon wild to imagine what might be in there."
