It wasn’t uncommon for Mammon to take you like this - without warning from the heat of the moment, expensive clothing ripped at the seams in a rushed effort to get you both undressed quicker, and hungry hands clawing at each other’s skin as he railed into you unforgivingly. In fact, it was more common than ever for Mammon to pull you into a random room in the house or school and fuck you in any way that he pleased - but this, you both knew, was different. It was animalistic, even.
To put it mildly, Mammon struck gold. From poker to blackjack to the slot machines, he was quite literally rolling in Grimm, and he felt as if his sin had never been so satisfied in his entire life. A Friday night at the casino turned into one of the best nights of his life, and he was all too convinced that it had everything to do with your presence. With your gentle hand in his, squeezing it for reassurance as he called out all the right moves and laid down the perfect cards, it was almost a given that his luck would never run out. Not with you at his side.
So, it’s not like Mammon could wait to kiss you so feverishly on the elevator ride up to your hotel room. The elevator door hadn’t even been closed before his hands were cemented on your waist and your legs were wrapped around his waist like it was the only place you belonged. Within seconds, your dress was hiked up to your stomach and Mammon’s slacks were around his ankles as he thrusted inside of you in one brutal go against the elevator wall, needing to feel the warmth in your slick walls the same way he needed air.
“You look so good like this, human,” Mammon couldn’t hide the big fat grin forming on his lips while he pressed them against your neck, the pleasured cries escaping yours sounding like music to his ears as you wept into his shoulder. “So pretty on The Great Mammon’s cock, huh?”
Mammon’s pace was unforgiving and relentless as he continued to fuck you into your tight hole, his smile turning into a smirk as he unexpectedly pulled back and then snapped his hips forward, slamming into you roughly without warning. It was impossible to hide that beautiful moan that escaped your lips.
“That’s my good girl,” his lips traveled to yours, his teeth tugging at your bottom lip now. The taste he found from it made him feel like a goddamn winner all over again. “That’s my very good girl.”
As Mammon continued to fuck you all the way to the next weekend, he couldn’t held but consider how lucky he was in this very moment. For winning thousands of Grimm in one night and satisfying his sin, of course - that’s a given, after all. But that wasn’t why the Avatar of Greed was feeling so lucky right about now. His greed was never limited to just money and gold, after all - at least not until you walked into the Devildom all that time ago. It wasn’t enough to simply have you around, or that you chose him over all of his brothers - Mammon wanted you every second of every hour, in any way that he could take you, as long as you would have him in return. To have you is to be the luckiest being in all of the three realms.
Within minutes, the coil inside of you both snapped as you shattered both in and against each other. Mammon coated your walls with thick layers of cum as he silenced your moans with a kiss that both defined you and consumed you, a kiss that said everything the two of you had ever felt about each other.
Mammon held you as tightly as possible as you both rode out the wave of your high - your blissful, perfect high. Slowly, the demon eased out of you and wrapped his arms around the small of your back, pressing your body as close to his as possible in a desperate attempt to have you as close as possible. If he could have it his way, there wouldn’t be a square inch of his skin that wasn’t covered by you.
“My beautiful treasure,” he cooed into your cheek, his own heating up in a crimson red now. “I love you so much, my beautiful human. I’m the luckiest demon in all of the Devildom.”
