Chapter 1: Feelings of the Truest Hearts

Chapter Text

Two day. In just two more days, she is returning back to the Human Realm. In two more days, he may not be able to see her face to face ever again. In just a few measly hours, his human would be gone. He wanted to spend more time with her, even if its just a mere few minutes. However, he does not know if she felt the same.

Ever since the day they were running from Levi, Mammon has been trying to avoid her, mostly because of the unspoken kissed they had before he ran away. Just the thought of it alone makes him feel embarrassed and ashamed. Granted, she was the one who kissed him, but he leaned in first. Maybe she just felt pressured by his sudden movement and that was her only resort to break the tension. Who would have known maybe she also did the same with his brothers.

Maybe she does love him the way he does.

Just then, Mammon heard a knock on his door. "Mammon, are you in there?" A familiar voice called from behind.

The demon quickly stood up from his couch, ready to open it. However, he hesitated, lowering his hand from the door's handle.

"Mammon, I know your in there." The voice said again. "Open up. I want to talk."

Taking in one deep breath, Mammon finally opened the door, letting the ever mentioned human in. As she walked in, she closed the door behind her, leaving the both of them alone, together.

"So, what do you want?" Mammon questioned, leaning against his pool table.

"You have been avoiding me." MC said bluntly. "I want to know what you have been avoiding me."

"pff, who said I've been avoid you?" He added, putting on his usual act. "Who told you? Asmo? Levi?"

"Yes, and all your other brothers." She replied, stepping closer to him with arms crossed. "I also noticed it myself. They told me not to think about, but I couldn't look pass this. So tell me Mammon, why are you avoiding me?"

Mammon turned away, refusing to look at her. However, something within him grew. Just having her standing so close before him is driving his crazy. "It's...It's none of your business, human."

She sighed at his stubbornness. Her expression relaxes as she continues to talk. "Mammon, I know that your lying. And knowing you, you wouldn't be avoiding me like this if something happened, which in this case...something happened."

Mammon looks up, realizing all this time, MC has been thinking about the same thing as he was. She the reached out and gently grab his arm. "So tell me, what is it your thinking."

The Avatar of Greed swallowed, words refusing to lave his mouth. He then pulled her arm away, eyes facing the ground. "Did you...did you not like the kiss?" She asks him softly.

Shocked by what she said, Mammon looked up and shook his head. "No, I did not hate it.."

"Then...do you not like me?"

Mammon blinked. "What?"

"Did you not like that it was me, a mere human, who kissed you?"

"oi..."

"Do you hate..."

"Enough!" Mammon yelled, grabbing both of her sides and pulling her close to him. "I did not hate our kiss. In fact, I wanted another before Leviathan interrupted us."

His sudden confession sent a blush to her face as he continued, heat rushing towards his cheeks. "I never once hated you. Never. I'm sorry if I ever made you feel like that. For the longest time, the only thing I felt for you is love, that that alone."

MC gasps when she heard what he said, her mind repeating his final line. Love? He loves her? All this time, that's all he felt?

"The reason why I have been avoid you is because I felt guilty for kissing you." Mammon finally admitted, leaning his head down. "I didn't want to force you to do anything you don't want."

"Mammon..." The said demon felt hands cup his cheeks, gently lifting his face up.

Coming face to face with the girl he loves, she slowly starts to lean it until their lips touched. Mammon's eyes widened, but he soon relaxed, placing his hands on her hips. He could feel MC's fingers glide against his skin and into his hair, combing through it, attempting the close the non-existent gap between them.

They soon separated, gasping for air as the leaned to each other's touch. "Mammon..."

"I love you MC." He confessed softly. "Always have. Whatever I said that day, it's all true."

She smiled and place a chaste kiss on his lips. "I love you too."

Wrapping his arms around her, Mammon leaned in once more, capturing her lips with his. This kiss was much rougher, almost suffocating, yet they feel more alive than ever. A soft sigh escaped MC's mouth as Mammon nipped on her lips, prompting her to open wider, until she could feel his tongue against her teeth. She quickly wrapped her arms around Mammon's neck, hoping to gain more access to his mouth. Just then, Mammon's grip on her hips tightened and he spun around, trapping her between the pool table and his body.

In a fit of passion, she quickly sat on top the pool table and remove her jacket, her lips still Mammon's. However, Mammon soon removed himself and stared at her, hands now on her thighs.

"Mammon, what wrong?" She asked him worriedly.

"I want you. I want you so badly." He admits, placing a hand on her cheeks. "But what if I hurt you?"

With an assuring look, she placed her hand on his. "I trust you."

Mammon gasped in awe, a mix of emotions bubbled within her before moving in to recapture her lips, all worry washes away.

With the added height, MC wraps her legs around Mammon's hips, pulling him closer, the sweet scent of flowers hitting him. Mammon then place a hand on her shoulder, giving an experimental lick inside her mouth. That action caused her to moan loudly but sweetly, like a sweet siren's song, sending him to a frenzy.

Mammon quickly removed his jacket and shirt with MC's help, revealing his well-toned by to her. She proceeded and run her hands across his abs before reaching down to unbuckle his belt while Mammon placed a kiss on her cheek, slowly moving down to the exposed parts of her neck and collarbone.

Moans escaped her mouth as Mammon advanced down her body, unbuttoning her shirt as he did. She shuttered against every rough kiss, licking her lips as sighs softly. Stopping at her sternum, Mammon proceeded to cup her breasts as he straightened back up, placing a chaste kiss on her forehead then on her lips. It was a blessing that MC hated wearing bras at night. It prevented another obstacle from coming in his way.

"You smell so good." He breathed.

The pair laugh against each other's lips as Mammon continue to massage her breasts, relishing in their fullness. "Your hands are amazing, babe." She whispered into his ear, hooking her arm on his shoulder, pulling him closer.

Mammon smiled against her collarbone. "It's that all? I can do if you want."

MC whimpered as he nipped against her now fully exposed collarbone, pushing her shirt away as he do the same with her shoulder. "Yes Mammon. I want more." She managed to moan out. "Give me more."

The demon smirked in satisfaction. "As you wish, my Treasure."

He started nipping down her chest once again, savoring all of her moans. He travelled down to her breasts, leaving kisses in between them. MC's moans grows louder when Mammon advanced to her nipples, rubbing and kissing against them before biting down. She moaned at the pain, squeezing him closer to her body, allowing him to plant harder kisses on her bosoms.

Then, his hands travelling down to her thighs, snaking underneath her skirt. She leaned back as she felt Mammon's fingers against her underwear, gasping when she soon felt his breath against it. She instinctively moves further back onto the pool table, placing her legs up onto it's surface as she removed her unbuttoned shirt, exposing her naked body.

Mammon smirked at the unexpectedly action, licking his lips as he began tugging against MC's underwear. "You're so well behaved, my Treasure. You wanted this for a long time, didn't you?"

"Mammon..." She moaned before he recaptures her lips once more, sliding her underwear off her as he did. She let out a sighed, immediately holding onto Mammon's body and leaning into his shoulder.

"It's a little awkward to do it up here. Let's do it somewhere more comfortable."

Without warning, Mammon lifts her body up, hooking her body around his waist. As they moved, she wrap her arms around him before leaning in for another kiss, savoring his mouth before she felt herself land on top of Mammon's bed.

Said demon stared down hungrily as he hovered over her, relishing in her beauty as he grind his hips against hers. MC notice his demeanor has completely shifted since earlier, and she loves it, she loves this side of him.

"Let me take care of you, Love. Let the Great Mammon take care of you one more time."

He leans in to give her a deep kiss, moving on of his hands into her skirt as he deepens it even further. She flinched as she felt Mammon's fingers touch her folds lightly, causing her to part her legs even further. She sighed as he travelled down her body, planting kiss after kiss, worshipping her.

Reaching the waistband of her skirt, he flips it up, revealing her well-plumped clit. Mammon sat up right, gently brushing his fingers across MC's legs, tickling her. Then, her laughter turn into deep sighs when she felt Mammon's fingers grazing her hole. She used her hands to pull her legs even further apart, wanting more of his touch.

Mammon shook head, leaning down to brush her hair away. "My needy little Treasure, do you want it that badly."

MC quickly shook her head. "I do."

"Good." He smiled before making his way down to her opening once more. He moves his hand against it, causing her to throw her head back against the pillows. Mammon smirked, just the reaction he expected.

"Feels good, right?" He earned a small nod. "I can make you feel even better."

Mammon kneels back down and planted his lips against her opening, kissing and sucking against her opening gently. She let out a soft moan, rolling her hips to his touch, begging for more. MC then felt Mammon's hand reach for her mouth. She happily accepts his fingers as he shoves them deeper, causing her to choke as she licks them one by one.

With a sadistic smile, Mammon removes his fingers, replacing them with his lips. Her tongue sought refugee in his mouth, cupping his cheeks so dearly as his fingers dip back to her heat. Then, she felt his fingers enter her without warning, causing a chill to travel down her spine.

"You feel so good." Mammon whispered against her lips, taking in her soft whines as he pushed his fingers down further. MC attempted to sit up, but Mammon pinned her down with his other hand.

"I said I would be the one to take care of you, babe. Let me take care of you."

A soft laughter escaped her as desire clouded her mind while Mammon continued to stretch her walls open with his fingers. She absentmindedly placed one of her legs on his shoulders as he nudged her opening with his nose, still pulling his fingers in and out of it. He then started planting kisses on it once again, sucking in all the juices that have already leaked out of her.

MC gasps as she felt Mammon's teeth graze across her heat, her hands combing through his hair as she moaned. "Mammon..."

The softness of her voice caused the demon before her to quicken his actions, digging and twisting his fingers into her before hitting a sweet spot. She instinctively tried to close her legs together, but Mammon quickly push her leg away with his free hand, adding one more finger into her before continuing with his advances.

Both pain and pleasure wash down her face as she reach the peak of her arousal, throwing her head back as Mammon gnawed against her opening last few times before sitting up, gently placing her leg back down on the bed. MC sighed as he removed his fingers out of her, her orgasm dripping from his fingers. She whined at the emptiness, making him smile.

"That's a lot." He purred, licking his fingers, taking in the last of her sweet essence. "You must have been holding on for a long time, eh."

She blushed at the comment, sweet dripping down her skin while Mammon pulled her up to meet his lips once again. MC brought her hands to cup his face, nipping against his lips, allowing her tongue to gain access to his mouth. Her hands made their way to the rim of his jean, fuddling and tugging against the belt before tossing it aside. She then impatiently tried to unbutton the jeans after noticing his hard bulge. However, Mammon stopped her, pushing her back down onto the bed.

"You're a real impatient on, aren't you my Treasure?" He smirked, standing up to undo his jeans and boxers.

MC sighed as she watch him discard the last of his fabric, smiling weakly at the sight of his hardened length. He was much bigger than she anticipated, but that only made her want him even more.

Climbing back on top of her, Mammon pushed her wet bangs away and kissed her on her forehead. He tore away her cum-soaked skirt away before pressing his length down against her swollen clit. MC convulsed against his touch, still feeling the pain from his earlier actions.

"Last chance, babe. Do you want to pull out or continue."

Mammon already knew what was her answer. He wants her. He wants to fill her up so badly. He wants her all for himself. He wants to make her scream until he fully claim her as his.

"Please Mammon." She pleaded as Mammon leaned down to place kisses on her neck. "Please. I want you."

With a satisfactory smile, Mammon hooks his arms underneath her legs, moving them up even further. "As you with, my Treasure."

He enters her as he laid a tender kiss on her shoulder, allowing his cock to slowly plunge into her with antagonizing slowness, inch by inch. MC whined, shifting a little as she felt him enter her. She threw her head and arms back, her walls clenching Mammon's length tightly as he moves sensationally slow into her.

Mammon watched as a pleasurable expression forms on her face as she pants through the pain. He leans down and places an assuring kiss on her lips. He shifts himself up once again, flooding her body with warmth. MC gasps against his mouth, shifting uncomfortably.

Allowing her a few seconds to adjust herself to his cock, Mammon glide his fingers down her body, sending a shiver down her godly body. "How are you feeling, babe? do you want more?"

Throwing her head onto his pillow, MC nods instantly through her whimpers. "Yes, Mammon. Plea-Please fuck me."

Mammon smiles, kneeling down before hoisting her legs up. "Of course."

Holding onto her hips, Mammon began to move himself in and out of her, enjoying the feeling of his skin slamming into hers. His earlier advances has made it easy for him to sip in and out of her, making his eagerness to trust his entire length right into her and release his seed to increase tenfold. However, Mammon wanted her to comfortable before he made any sudden movements.

MC whined with every steady thrust, savoring warmth his length gave her. She loves the feeling of him inside her, feeling herself fall apart with every thrust. With unsteady breaths, she starts rolling her hips against him, wanting more of his length inside her. Mammon smiled at her neediness, tightening his hold around her hip before he increased his speed, thrusting into her at a faster pace.

He continued pounding in her, her entire body bouncing to the rhythm. As symphonies of whines and moans escaped her, Mammon snapped his hips forward, slamming into her harder and harder until he hits her sweet spot, causing MC to let out a scream. The sudden fullness in her body caused her to lift herself up on her elbows, leaning back and buckling herself as Mammon continued with his advances.

"Mammon, please.." She moaned, feeling him hardening inside her. "More..."

"God, you feel so goddamn good." He groaned, rubbing her breast with his hand. "I'm going to fill you up feel good. My Treasure."

Strings of moans pierce through MC's voice as Mammon readjusted himself, using the opportunity to quicken his pace. His grip on her hips tighten, his nails digging her skin. She throws her head back, squeezing her bosoms as she felt the tip of his length hit her cervix, sweet whimpers leaving her mouth. Mammon then place his hands on her knees and moved them further apart, pounding into her faster and faster in a new rhythm, groaning and swearing as he felt her tighten around him.

"That's right. Cum for me."

"Mammon..." MC stretched an arm towards Mammon, holding onto him before pulling herself up, wrapping her arms and legs around his shoulders and waist respectively, leaning against him.

Mammon was surprised by her actions, shifting himself to his new position. He was not too sure what to do next. However, after a reassuring nudge from her, he crashes his lips into hers.

Like before, he continues to thrust his cock into her, gauging against the sensitive part of her neck, taking in her scent as he did. MC rolled her hips, following the rhythm of his as her hands travelled down his sweaty back, leaving scratches on his unblemished skin. Whimpers and moans left their mouths as her walls began to clamp down tighter against Mammon's length, causing said demon to wince, feeling himself reaching his peak.

They kissed once again and before they knew it, their bodies collapse back onto the mattress. Mammon slowly thrusts into MC few more times, her arousal staining the bedsheets. Her vision went white when Mammon finally stopped, his length fully enveloped within her, filling her up with his seed.

Sweat dripped down their foreheads as they leaned against one another, panting hard to catch their breaths.

Mammon reached down to cup MC's cheek, which she happily accepted, kissing the palm of his hand. She let out a loud moan in protest as Mammon pulled his length out of her body, but was greeted again with hungry kisses from her beloved. Mammon was more than just her 'first demon'.

He was the first person she ever love so dearly. Her first love. Her first true love.

Mammon remained above her, hugging her tightly but gently, refusing to let go. MC nuzzled against his touch, wrapping her arms around him as she shifts her legs against his. "Are you feeling okay?" He asked, nipping against her earlobe. He was now back to his usual self.

"hm, better than okay." She hummed, smiling into his neck.

He then rose up once again to look at MC eye to eye, running his hand through her wet bangs, tugging it behind her ear. "Listen, what I said that day, I really mean it." He confesses, a pink shade forming on his cheeks. "Stay here in the Devildom. I don't want to lose you."

MC smiled at him sadly. In truth, she wants to stay, but the Human Realm is her home, and she misses it just as much.

She sat herself up, cupping Mammon's face so dearly. "I don't want to lose you too." She admits solemnly, but a soft smile appears on her face. "But, I'll can summon you whenever I can. We can still talk and message each our on our D.D.D."

"The most important thing is I'll always have you in my heart."

Mammon's heart fluttered as MC leaned her forehead against his, able to hear the sincerity in her words. He leans back to her touch, holding his hands over hers. "I love you, MC. You're mine, and mine alone."

The human hummed at his words. "I love you too. My dear Mammon."
