Friends (With Benefits)

Minors DNI

A/N: Fair warning this is a mammonxoc smut-not a very good one but its a smut nonetheless- because its just that kinda day... It’s not the first one I’ve written but it’s the first one I’ve ever posted that hasn’t been part of a role play so... yeah. Do with that info what you will...

I'm not participating in kinktober but since its that time of year I figured eh why the hell not. Now, if you excuse me. I need some water.

Also I’m doing that 48hr post+ protest so any comments questions or concerns will be heard on the 4th.

Warning(s)?: unprotected sex, oral sex (Female receiving) size kink (if you squint)

Gods she needed to get off. She’d been down here on the exchange programme for about six months at this point and yeah, Asmodeus made it a point to make sure she had plenty of quality toys at her disposal for the year, but it just wasn’t as satisfying as the real thing. Not to mention, she never had a moment’s peace in this god-forsaken house to begin with. It was common place for Arella to come home to Mammon or one of his brothers making themselves at home here in her room or just barging in whenever they felt like it- no better way to kill the mood than getting walked in on by one of her housemates.

In fact, that’s the case today. Arella had come home a little earlier than the others due to them being stuck for a student council meeting for the express purpose of having some privacy and time to relieve her frustrations without risking the chance that one of those pesky demons would interrupt her. Of course, that wasn’t the case for her as waiting on her bed was the Avatar of Greed himself scrolling through his phone like it was no big deal- dressed in only a pair of grey sweat pants because of course he would be.

It was a nice view though. Despite Mammon’s frustrating hot-’n-cold attitude sometimes, he always is pleasing to look at and now in her desire-addled mind, Arella finds herself scanning over his form as her eyes drift lower and lower until...

“Ya gonna just stand there or...?” Mammon calls, not looking away from the screen of his phone.

Her face flushes at the notion that he’s caught her eyeing him up like a piece a meat. “Why’re you in here, Mammon? Surely, you have better things to do since you’re always so busy.”

“Well yeah, naturally, I’ve always got shit ta do but I said we were gonna do movie night after school today so...”

“Can you give me a few hours, please? I... have to take care of something.” Arella sighs when the demon makes no effort to leave but rather shifts a little to the point that the material of his pants leaves astoundingly little to the imagination.

She audibly swallows, trying so hard not to stare. Arella has to look away, her face an impossibly bright shade of red as her mind starts to wander into the gutter. She could always order him away with the pact but she always did hate using it unnecessarily. It’s not until she sees the smirk on his face that she knows he’s fucking with her.

“What’s so important that I can’t be here, huh?” Mammon drops his phone on the bed beside him.

“That smirk on your face tells me you know exactly why.” The human glares at him.

“Yeah ‘n that’s why ‘m not goin’,” The Avatar of Greed laughs, “Yer jus’ gonna have to suffer, Princess.”

“You are absolutely horrible, you know that?” Arella sighs in frustration. “C’mon, Mammon, just go, please. Unlike you, who has the luxury of going out to find a partner when you need to get laid, I can’t for risk that they’ll eat me afterwards so I have to take care of myself when it comes to that.”

“You could always just ask me to help ya...” The demon suggests. “Ever heard of the term ‘friends with benefits’?”

“Huh- Wha- I – Of course, I’ve heard of the term!” She crosses her arms as she huffs. “But friends with benefits only works when both parties don’t run the risk of catching feelings. And you strike me as the type who does.”

“What? No. Couldn’t be me.” The demon rolls his eyes as he looks away, “’sides you’d be doin’ me a favor too and ya can’t tell me that yer not even a little curious about what I’m like in bed. I heard ya this morning. Moanin’ my name and beggin’ me for more.” A smug smirk paints itself on his face as he gets up, approaching her, walking her back until she’s trapped between him and the wall. “Well? Ya got your chance with The Great Mammon now... ya gonna take it or blow it?”

Arella bites her lip as she mulls it over. It wasn’t like he was wrong. She did fantasize about him more than she should for someone who she considers a friend. “Fuck it,” she murmurs as she surges forward to capture his lips in a heated kiss as she pushes him back towards her bed.

If the need wasn’t so urgent, she’d take her time with Mammon, but honestly, going for six months without any chance for release when she was used to being able to have it whenever only made her more desperate to find it now. Her hands traveled all along the demon’s body as she straddled his hips. She let out a soft moan as he shoved his tongue in her mouth and he rolled them over, grinding his hips against hers. He broke their kiss only to trail them down to her neck where he nibbled and sucked little love bites into the delicate skin on her neck.

Arella’s fingers carded through his snowy hair as she panted, head tilting to the side as he moved, his hands coming up work on unbuttoning her unform shirt, tossing it to the side once it was off. He wasn’t so gentle with her bra, choosing to rip it off and toss it away as if the article of clothing had offended him somehow.

“Mammon!” she gasped as she watched it go.

“What? Ya got a hundred more where that came from. If it’s that big a deal I’ll by ya a new one.” the greedy demon growls as he trails his lips down her chest, taking one of her nipples into his mouth and sucking as his fingers pinched and rolled the other one. Every once and a while he would lightly nip at her before circling it with his tongue. Arella would only tug at his hair impatiently signaling him to get on with it as he chuckled. “Here, get these wet for me.”

He prods her lips with his fingers and she takes them in her mouth, sucking and swirling her tongue around them as he pushed them in further to the point that she was nearly gagging on them as he works on ridding her of her skirt and panties. As they slid down her legs, he pressed open-mouthed kisses to her inner thighs, withdrawing his fingers from her mouth and tracing them down her stomach. He let his warm breath tease for a bit as she tried to rock her hips to spur him to action.

“Impatient, ain’t ya, Baby?” He chuckled, “Just hold still, you’ll get what ya want.”

“If you’d stop teasing, maybe I would,” she pouts, just wanting to feel him where she needed it most.

“As you wish, Princess.” The demon smirks as he spreads her open and licks a stripe from her opening to her clit and she could almost cry at how good it feels when he starts to gently suckle on the sensitive nub.

“Fuuuck, yes, right there,” She gasps at the feeling of his mouth on her and the prodding of one of his long fingers at her opening followed soon by a second. “Don’t stop...”

Her head tips back as she lets a pleasured sigh fall from her mouth, her hand coming down to knot itself in Mammon’s fleecy white hair to push him closer, drawing a moan from the demon. He has her dangerously close to the edge of oblivion without having even done much of anything.

“I’m so close, Baby, keep going.” she rocks her hips to match pace of his fingers before he pulls them away only to replace them with his tongue and she lets out a frantic cry as she feels the wet muscle work its way against her walls while his thumb rubbed tight circles around her clit.

“Don’t hold back. Let me have it.” He growls out as he returns to his ministrations and she absolutely loses it, body going tense as she lets out a strangled moan and she clenches around his tongue as she cries out his name.

The demon cleans her up as he helps her ride out her high before pulling away, making a show of licking his lips as he crawls his way back up her body. He leans down for another kiss and Arella moans at how she can taste herself on his lips and tongue. She used her knee to brush against his crotch listening to the beautiful groan he lets out at the sensation.

“Get those off,” The human says in reference to his sweat pants that now have a large stain of pre covering the front. “You need more or are you good to go right away?”

“Nah, I’m good.” He pushes himself up on his knees and slowly rids himself of his sweat pants allowing his cock to spring up, slapping against his belly.

Her jaw drops at the sight of him. She knew he was big- but damn. He absolutely would tear her apart if they we’re careful- and are those piercings? She can feel her mouth start to water as she looks up at him to see the predatory look in his eyes that were now a shining gold.

“That shut ya up real fast, didn’t it?” He chuckled as he lined himself up. “You ready or do you need a minute?”

“No, I’m fine.” A determined look crossed her eyes. “I’m more than ready.”

“Got a safe word?”

“Just use the traffic light system.” She hooks a leg over his hips to bring him closer. “I want this.”

The stretch she feels as Mammon enters her is as delicious as it is painful even with him taking breaks to let her adjust. Once he’s fully seated, he keeps still as she takes a moment to savor it. With a nod from her, he begins to rock his hips gently, upping his pace as he draws more moans and gasps and the occasional whine from his human. Soon he’s pounding into her as he slips into his demon form.

Her hands are at his back, digging into the skin near the base of his wings and scratching angry red lines down his back. She’s so tight around him that it’s intoxicating to the demon as he lets out a growl. He can feel her next climax is imminent by the way her walls are clenching and gripping him and the breathy pitchy cries of his name- by the way her eyes are nearly rolled back into her head as he pulls her legs up over his hips to hit deeper. The pleasure is overwhelming as his piercings drag along her walls and she cums for the second time that afternoon.

He slows his pace in consideration of the human but he never stops all together. As she starts to squirm from the overstimulation, Mammon holds her still.

“What’s your color, Baby?”

“Green,” Arella looks up at him and pulls him back down by the horns for a tongue filled kiss as he picks his pace back up.

She ran her fingers against the curls of his horns as the demon goes back to biting and sucking on her neck as the only sounds that could be heard were the sounds of their moans, growls, and gasps and the sound of skin slapping against skin. “More! I need more, Mammon. Please.” She has tears slipping down her cheeks from the overstimulation. “It's so good... you’re so big...”

He growls as he hoists her legs up over his shoulders, nearly folding her in half as he thrust into her at a near animalistic pace hitting the deepest part of her as she cried for him. He was getting close to his release as he grasped her hand in his.

“Almost there... so close... Just keep squeezin’ me like that.”

“Me too!” Arella threw her head back, “Fuck, I’m so close. Cum inside.”

“Yer playin’ with fire, Princess. Ya really want that from me?”

“Yes! Yes!” Her grip on his hand tightened as she threw her head back. “Fill me up.”

He groaned as he felt her walls tighten once more as she hit her last release. “Shit... haah... fuck. I’m cumming!” Mammon buries his face in her neck as his thrusts falter. His cock twitches as he fills her with his seed until she’s overflowing with a mixture of their fluids.

They ride out their highs together, letting out soft groans and gasps as the demon pulls her legs down from his shoulders. They stare at each other as they try to catch their breath, wide-eyed, sweaty messes before bursting into a fit a laughter.

“I can’t believe we did that,” He sighs as he leans his forehead against hers.

“That was... amazing...” She sighs, “Best sex I’ve had ever had... I don’t know about you but I need a nap after we shower and change the sheets.”

“Yeah, I second that...” Mammon groans as he pulls out and rolls out of bed. “I’ll start the water; you just pull the sheets off.”

Arella only gave him a thumbs up as she sat up, feeling considerably better than she had before she’d gotten home from school.
