In the IMP building, Y/N was sleeping on Roxanne's lap in his crow form. It's been a few days since the K-9 Unit of IMP was established and they've been getting jobs done.

Millie: Hey there Rox, mind if I borrow Puddin for a sec?

Roxanne: "Puddin?" You mean this derp right here? Yeah, I don't own him.

Roxanne picked up Y/N as if he was a burger before giving her to Millie. Millie happily holds Y/N and walks away. Millie placed Y/N on a couch in the break room and gently poked him to wake him up.

Millie: Puddin', wake up~.

Y/N bursts into a cloud of feathers, revealing his human form as he rubbed his eyes. He was able to make out Moxxie and Millie in front of him. Millie was smiling happily whereas Moxxie was rather nervous.

Y/N: Millie? What happened?

Millie: Wellll~, Moxxie and I have been talking and we wanna reward ya!

Y/N: Reward me? For what?

Moxxie: F-for helping me at the Pain Games.

Y/N thinks back, remembering how he dragged Moxxie out of trouble at the Pain Games, helping him around the farm, letting him vent about Millie's parents, basically being a good boyfriend for Moxxie.

Y/N: Aw Mox, I'll always help you. I may fuck you and Millie, but I still care about you two.

Millie: And that's why we're going on a date today, all three of us!

Y/N: Wait, wait, wait, a date? With both of you? As in, a threesome?

Millie: Yes! And not just any threesome either, this will be our first time having one together!

That was accurate. Even if Y/N has had sex with Moxxie and Millie when he came to Hell, he surprisingly never had a threesome with them both. It was usually one masturbating to the other getting fucked, cuddling, or Moxxie and Millie pleasing his dick together.

Moxxie: We already talked about it and agreed, so don't worry!

Y/N: Okay then. Where are we going?

Millie: You'll find out soon enough, now come on!

Y/N: Alrighty!

Minor Timeskip
Y/N looked at his outfit in the mirror. The outfit consisted of a white dress shirt and a pair of black pants with black loafers to tie the look together. His hair was tied into a high ponytail, which made his bangs stick out a bit more than usual. He went to go grab his phone and keys before heading down the stairs.

Millie: Hey puddin'!

Y/N: Hi sweetheart.

Millie: How do you like my outfit?

Millie does a small twirl, showing off her fitting black dress.

Y/N: You look beautiful, Millie.

Millie smiled and blushed a little at the compliment, looking down shyly. Moxxie walked over to her and gave her a gentle kiss on the cheek, making her smile even brighter. Y/N couldn't help but grin seeing his lovers like this. They were perfect for each other.

Y/N: You two are just so fucking adorable. Even a steamy kiss between you two is just adorable.

The two Imps get redder in the face, making him chuckle even more. They eventually get into Y/N's car and he drives off with Millie guiding him to where they're going for their date. 

After driving through the city for a few minutes, they finally arrive at their destination.

Y/N: Where are we?

Millie: We're here at a fancy restaurant called "La Cocina".

Y/N: Oh cool! Are we gonna have a romantic dinner there?

Millie: Yep! Isn't that exciting?

Y/N: Yes!

They all got out of the car and entered the building. There were candles lit up everywhere and the lights were dimmed. Soft music played in the background while everyone sat at tables enjoying their meals. A man in a tuxedo greeted them.

Man: Welcome to La Cocina, how many people are there?

Millie: Three.

Y/N: And we'd like a table by the window please.

Man: Of course sir, right this way.

He led them to a booth near the windows overlooking the street below. They took their seats and ordered drinks while waiting for their food to arrive. Y/N looked at the menu and slightly cringed at the prices.

Y/N: Well, at least I got a shit load from stealing from Gato.

Moxxie: No no no, we got it covered.

Millie: That's right, we paid for your meal as well!

Y/N: Ooh, you're so good to me.

He says in a playfully southern woman tone. The three laugh at his antics before finally getting their drinks. After the waiter leaves, they start talking about Y/N's life prior to coming to Hell after he died.

Y/N: So yeah. I was raised by an abusive Christian cult up until I was 18.

Moxxie: How did you leave? It sounded pretty....

Millie: Pretty fucked up Puddin'.

Y/N: Oh that was easy. See they wanted me to go to this Theology school in Alabama, so I applied and got all of the papers. What I was really doing was applying to a completely different school in the South for Gunsmithing, Precision Manufacturing, and Metal Fabrication just to get away from them. It was fun though, getting into dumb trouble almost every week and passing all of my classes. And believe me, they were PISSED when they found out what I did but by then it was too late. I got offered a well paying job and could buy an apartment for myself.

Millie rests a hand on Y/N's as does Moxxie.

Millie: What's important is you made it out of there Puddin'.

Moxxie: I agree, you're stronger than all of us for not letting your past experiences and traumas keep you from living a happy life.

Y/N: Thanks guys. And now I'm here with you two, who mean everything to me.

Millie: Aw Puddin', I love you.

She gives him a soft peck on the lips. Moxxie then kisses him as well, making him blush bright red. He pulls them both in for a hug.

Y/N: I love y'all too. Now let's enjoy this nice dinner!

After some more talk and laughter, the three of them finish their meal. They pay and head out of the restaurant.

Millie: That was amazing! I can't wait for dessert.

Y/N: Where we going for that? Didn't La Cocina sell dessert?

Millie: Yeah but who wants to spend $20 on a slice of cake?

Y/N: You got a point there Mills.

Moxxie: We're going to the Cheesecake Factory.

Y/N: Oh shit they have one of those in Hell?

Moxxie: Of course they do. Me and Millie have a coupon so it isn't a problem.

Nodding, Y/N drove the two to a Cheesecake Factory in Hell. 

Timeskip
Moxxie and Millie were having a small conversation, one they'd been having since they left the Cheesecake Factory.

Millie: I'm just sayin' Mox, usually Skittles are better than M&M's.

Moxxie: While I don't condemn you, I have to disagree. Y/N, what do you think?

Y/N: Well....depends on the context.

M&M: Context?

Moxxie: We aren't dealing with words or scenarios Y/N.

Y/N: No I know, but what I mean is it depends on the situation. Like at the Cheesecake factory, my slice had M&M's. I prefer M&M's when it comes to baked sweets but Skittles are better to mix with liquor or some types of Pop. I prefer Skittles in the summer, but sometimes I like M&M's during the summer because they taste pretty good melted.

The two make an 'oh' face and nod.

Millie: That's a smart way to look at it Puddin'. Make yourself comfortable, me and Mox gotta get out these date clothes.

Y/N nodded and sat on the couch before they left him by himself. As he waited, he started thinking of his time in Hell. While Angel Dust was his first lover, Valentino's demanding nature takes up most of his schedule. They manage to have cute coffee or movie dates about once every two weeks, but it's almost impossible to schedule a real date. It's something that makes Y/N angry and sad, sad he can't spend time with Angel as he would like but angry he can't do anything due to Valentino being an Overlord.

Millie: Hey Puddin', can you come here for a second?

Snapping out of his stupor, Y/N walked to their bedroom. He gently knocked on the door.

Y/N: What's up?

Millie: We need you to come in and answer something for us.

Shrugging, he walked in and was met with an unexpected surprise.

Millie: We wanna know what kind of M&M's you like. Regular~?

Millie was bent over, wearing a pair of short shorts with the M&M's logo on them.

Millie: Or Peanut~?

A blushing Moxxie was in the same position as his wife, only his shorts were designed after the Peanut M&M's package. 

Either way, both of their bubble butts were accentuated by their tight shorts. Y/N's cock twitched at the sight.

Millie: Or maybe even Peanut Butter~?

Moxxie: Maybe even Dark Chocolate~?

Millie: Or Dark Chocolate Mint~?

Both of them slowly stood up, facing Y/N as they removed their shirts. Both of them were now completely naked and hard, or dripping in Millie's case. Their asses were shaking seductively as they moved closer to him, hands behind their backs.

Y/N: Shit both of you, you're so sexy. But....I like my M&M's like I like my bitches.

Millie and Moxxie both blushed at the comment and leaned forward, pressing their lips against Y/N's. They moaned softly as he kissed them deeply, arms wrapping around their waists. They pulled back, gazing lovingly at their mate.

Moxxie: Then what's your favorite?

Y/N: Plain.

Millie: Hmm, plain? Interesting choice. Why's that?

Y/N: Because they're simple and pure. Just like the two of you. I love you both so much.

Millie: Aw Puddin', that's so sweet~!

Millie wrapped her legs around Y/N's waist, making out with him in front of her fat-assed husband. Not wanting to be left out, Moxxie started helping Y/N out of his dressy clothes. Y/N put Millie down and got out of his clothes, his muscular body and rock hard cock standing at attention from the sexy Imps.

Y/N: Can I ask you both something?

Moxxie: Go ahead.

Y/N: What's our safe word?

Millie: Fuck me harder daddy~!

Y/N: Perfect.

He picked up Millie again and carried her to their bed, laying her down gently. He then turned to Moxxie and grabbed him by his throat, pulling him close. 

Y/N: I'm gonna take you both tonight. And I'm gonna make sure you feel every inch of me inside of you. Got it?

Moxxie nodded in agreement, eyes widening as Y/N pulled him onto the bed next to Millie. Y/N then got between them, letting Moxxie straddle his waist. Y/N's fat cock nestled itself between Moxxie's plump ass. He reached down to rub Moxxie's hole, spreading it open and feeling it squeeze around his fingers. While doing that, he teased Millie with his tongue and teeth, licking her neck and sucking on her nipples. She moaned loudly, arching her back to push herself against Y/N's mouth. Y/N continued to lick and suck on her breasts, moving lower to tease her pussy. He spread her labia apart with his fingers, tasting her juices. She squirmed under his touch, grinding against his hand and moaning louder.

Y/N: You ready for me?

Moxxie: Y-yes Daddy.

Millie: I'm ready for you Puddin~!

Y/N: Good, cause I'm ready for the both of you.

He positioned himself at the entrance of Moxxie's ass and pushed in slowly, feeling the muscles of his hole grip tightly around him. Moxxie gasped as Y/N filled him completely, taking his time to adjust to the size of his cock. When he was fully seated, Moxxie began bouncing gently, gradually picking up speed as he relaxed and opened wider. He felt the walls of his hole squeezing tightly around him, sending waves of pleasure through him. He groaned in pleasure, reaching up to hold onto Moxxie's hips as he made it go in deeper and deeper. Moxxie couldn't control his moans and started cumming, using Y/N's chest to support himself as he bounced up and down. Y/N swapped to missionary and held him firmly, thrusting deeper and deeper into his tight hole. He could feel Moxxie's ass clenching around him, milking him for all he was worth. He leaned down to kiss Moxxie passionately, running his tongue along his bottom lip before biting down lightly. Moxxie moaned into the kiss, pushing back against Y/N's hips as they both started fucking harder and faster.

Millie: Oh my god, I wish I could see that.

He pulled out of Moxxie and laid him down next to Millie, who was eagerly waiting for what action Y/N had planned.

Y/N: Hey Mills, how about riding this sexy little twink while I fuck him?

Nodding excitedly, Millie wastes no time riding the still-sensitive Moxxie in a reverse mating press while Y/N fucked his tight hole. Moxxie moaned in pleasure, being stimulated from Millie's tight pussy gripping his sensitive cock and Y/N's girthy cock pounding away at his ass. Millie rode Moxxie harder and harder, bouncing up and down on his cock while Y/N continued to pound her husband. Both of them cried out in pleasure as they neared orgasm, their holes stretching from the respective penetration. Y/N grunted in pleasure as he continued to fuck Moxxie, slamming into him hard and fast.

Y/N: Fuck your ass is tight, but lose enough to fuck. Damn Millie must peg you like crazy.

The degradation from Y/N only fueled Moxxie's lust, feeling himself cum prematurely inside of Millie. And at a good time too as Y/N started hitting his prostate with his thrusts. Moxxie's ass became tighter from cumming, making Y/N groan in pleasure.

Y/N: That's a good boy, you want my cum deep in your ass don't you?

Moxxie: Y-yes Daddy. Please fill me up.

Y/N: Go ahead, beg for it.

Moxxie: FUCK ME DADDY! Fill my tight hole with your hot seed!

Y/N: That's a good boy.

Y/N: That's a good boy.

With those words, Y/N let his knot grow and locked it into place, shooting rope after rope of hot seed deep into Moxxie. Y/N pulled out of the Imp's ass, leaving it gaping and leaking his cum. He then turned to Millie, who was arching her back in a doggy position, and thrusted into her tight hole, causing her to cry out in pleasure. Y/N slammed into her harder and harder, making her scream in pleasure as he hit her g spot over and over again. She began to shake and quiver, cumming all over his cock. Y/N grunted in pleasure as he continued to fuck her, slamming into her harder as if he was attempting to breed her. Y/N gave her fat ass a firm slap, watching her red cheeks ripple from the impact. Millie moaned loudly, her body trembling as she felt Y/N's knot grow inside of her. He thrust deeper, his hips moving in a rhythm that left her breathless. Her pussy clenched around him, desperate to milk every last drop of his cum. 

Meanwhile, Moxxie was feeling conflicted, in a good way. On one hand, he enjoyed seeing Y/N fuck Millie as if she belonged to him, making her make faces she never made with Moxxie. On the other, it hurts his pride as a man seeing someone like Y/N not only fuck Millie better than him, but also emasculated him by fucking him brutally. Moxxie's heart raced as he watched Y/N take Millie from behind, her body convulsing with pleasure. He couldn't help but feel a pang of jealousy and submission at the same time, his mind filled with conflicting emotions. A part of him wanted to leave, to distance himself from the humiliation he felt at that moment, but another part of him craved Y/N's attention and dominance. As Millie cried out in pleasure, Y/N turned his attention back to Moxxie. He had a sinister grin on his face, and Moxxie couldn't help but feel a shiver of fear and arousal run down his spine. Morphing his tail, Y/N grabbed Moxxie's cock roughly, jerking him off while he watched the scene unfold before him.

Y/N: You like seeing me dominate your precious Millie, don't you?

Moxxie stared at Y/N, his eyes wide with surprise and a hint of excitement. He had never considered himself submissive, but there was something undeniably attractive about Y/N's dominance. The thought of giving up control and allowing Y/N to take charge sent shivers down his spine. Moxxie hesitated, biting his lip as he tried to reconcile his desires with his pride. He didn't want to seem weak in front of Y/N, but the sight of Y/N fucking Millie and the feel of his tail jerking him off were driving him wild.

Moxxie: D-Daddy, I w-want you to dominate me...

Smirking, Y/N kept fucking Millie until he felt his cock twitch in her tight, wet hole. He reached down and grabbed her hips, thrusting harder and faster, causing her to cry out in pleasure once more. Y/N could feel the familiar sensation of his knot growing inside of her, and he knew it was only a matter of time before he would breed her. As he continued to fuck her, Y/N glanced back at Moxxie, who had now taken on a submissive demeanor. His orgasm was imminent, and he couldn't hold it in any longer. Y/N thrust once more, causing Millie to cry out in pleasure as he unloaded his seed deep inside her. Then, with a final groan, Y/N pulled out of Millie, leaving her gasping for breath.

Turning his attention back to Moxxie, he smirked as he saw the mixed emotions playing across his face. Y/N knew that Moxxie's submission was just a glimpse of the desire that lay within him. Moxxie bent over and arched his back, presenting Y/N his hole that oozed a bit of the hybrid's seed. Y/N stepped forward, his thick cock glistening with Millie's juices. With a wicked grin, he positioned himself at Moxxie's entrance. He thrust into Moxxie's submissive hole, feeling the resistance but knowing it would only last a moment. Moxxie cried out, the pain quickly turning into pleasure as Y/N's cock filled him completely. Moxxie moaned loudly, his fat ass clapping whenever it hits Y/N's pelvis.

Y/N's knot swelled inside Moxxie, and he knew he was about to cum. The sensation was overwhelming, and he felt a wave of pleasure wash over him. With a final thrust, Y/N buried his cock deep inside Moxxie, breeding him as if he was a bitch in heat. Moxxie moaned loudly as he came himself, staining the bed. Y/N pulled out, letting his cum drip ooze out of Moxxie, before laying on the bed.

Y/N: Fuck that felt good...

Y/N groaned, suddenly feeling something pleasurable on his shaft. He looked to see Moxxie and Millie worshiping his dick with hearts in there eyes.

Millie: Come on Puddin', fuck us more~!

Moxxie: P-please Daddy~?

Y/N chuckled, running his hands through their hair.

Y/N: Alright, I love M&M's.
