As your Friday student council meeting wraps up, Lucifer, like always, asks if you guys have any questions. No one ever does, excited to be done with the week, but today you raise your hand causing him to do a double take.
“Yes?” you can feel Mammon glaring at you for drawing on the meeting any longer than it needs to go, but you’re curious and a bit concerned.
“Where’s Dia–” Lucifer opens his mouth to correct you, so you clear your throat and try again, “Where’s Lord Diavolo?” you ask. Before he has the chance to answer you hear Asmodeus giggle,
“He’s probably dealing with his milk.” You turn to Asmo, a look of complete bewilderment crossing your face. He opens his mouth to explain further but catches the gaze of a very pissed Lucifer and decides against it. “Ah forget I said anything love, but rest assured he’ll be here next week,” he supplies, offering you a somewhat nervous smile. You turn back to Lucifer who nods curtly,
“Yes, he’s busy with something, and conversely, will not be busy with it next week. Alright meeting adjourned,” everyone hijacks it out of the room, leaving you confused in the dust.
On your way back to the house of Lamentation you can’t stop thinking about what Asmo said, rather what he didn’t say. What are they being so secretive about? Your curiosity gets the best of you and you reroute to the castle. When you arrive unannounced, which you know Barbatos hates but this is an emergency (maybe?), said butler greets you,
“What can I do for you?” you shift from foot to foot looking around for any sign of the cheerful demon prince.
“Um, I’m just wondering where Dia is,” you explain. Barbatos gives you an absolutely unreadable expression before bringing his hand to his chin and smiling,
“Ah, the young master is dealing with… an uncomfortable annoyance right now,” seems like everyone is giving you cryptic answers today, “though, if you would like to, perhaps you can help him.” You perk up at his suggestion,
“Oh of course! What can I do?” Barbatos turns, and you follow,
“I’m sure he would rather tell you that himself,” he says as he leads you to Diavolo’s room. He stops you before you enter, “call if you need anything,” he pauses before adding, “and remember that the young master is not human.” You bark out a laugh, a little surprised by the random statement.
“um , Ohhh-kay?” with that Barbatos knocks then exits, and from the inside you hear Diavolo cry “come in”. So you let yourself in.
Dia is lying on the bed, surrounded by tissues. He’s not wearing a shirt, causing you, and him, to flush. He pulls his covers up to his chin, while concern crosses his face,
“Did you need something? Is there a problem I should be aware of?” You shake your head while you remove your jacket, and set down your bag on the chair in a corner.
“No, everything’s fine, I was just worried when you didn’t show up, and then Asmo said something weird when I asked,” Dia pales at your words.
“Weird?” You nod,
“Yeah, he said you were dealing with your milk?” Honestly, you’re starting to get frustrated with how strange everyone is acting right now. Diavolo bites his lip, avoiding eye contact. “Will you explain what’s wrong with you? No one is telling me what’s going on,” you complain as you sit on the edge of his bed.
“Yes, right! I suppose you don’t have context with being an exchange student and all… although they should have taught this in your demon anatomy class, were you not paying attention?” he rambles fiddling with a tissue.
“I feel like you’re avoiding the issue.”
“Right right, my apologies, ah, I’m secreting milk right now, because I did not produce offspring, so my body has to get rid of what it was storing up-”
“You’re lactating?” You cut him off as you process his words, a little baffled.
“Yes,” he squeaks, sounding so uncharacteristically nervous. You offer what you hope is a reassuring smile even though your mind is reeling,
“Okay! Um… does it hurt?” you ask carefully. Diavolo sighs,
“Oh terribly so,” he whines, jutting out his bottom lip as he pouts. You hum softly, scooting closer,
“Is there a way I could help?” you test hesitantly. Dia looks at you with big puppy eyes,
“You want to help me?” you nod and Diavolo beams, returning to his joyous self, “thank you!” He drops the blanket to grab your hand appreciatively. You can’t help but look at his swollen chest, nipples red and puffy, with a bit of white liquid leaking out. You feel your dick twitch with interest. “I usually squeeze them and wipe up the excess milk with tissues…” he trails off. Seems like a waste to you, but you keep that to yourself.
“Yeah, I can do that,” you’re kind of in a daze, unsure about what to do next, “should I sit on your lap?” Diavolo makes a surprised sound at your suggestion,
“Yes! Please do,” he pats his lap and you suppress your urge to laugh at his enthusiasm. It takes a few minutes for you to settle, but you end up sitting on Dia’s thighs, cupping his chest gently, as his hands clutch the sheets.
“Um, okay, I’m going to start now… tell me if I do something wrong,” Dia nods, looking up at you intently. You squeeze his pecs- really they’re more like a cup tits now, completely entranced with watching the milky white liquid leave him. Your mouth salivates, and you push the fantasies of drinking his milk into the back of your mind. Diavolo lets out a soft sigh, letting his head fall back against the pillow and arching his chest a bit into your touch. You squeeze again, closer to his nipple and this time more milk pours out, at a faster speed as well. You grab a tissue and wipe up the liquid, pausing when he lets out a pained whine. “What’s wrong?” you ask, your voice an octave deeper.
“I’m alright, no need for concern,” he pants out, brows furrowed, “it’s just, ah, you wiped my nipples and they’re very sensitive, as I’m sure you can imagine. It’s no issue though, I can withstand it,” you hum, deep in thought at his words.
“Um,” you start, throwing the tissue elsewhere on the bed, “what if we tried a different method?” oh you need to shut your mouth before you say something stupid. Diavolo cocks his head,
“What do you have in mind?” fuck. Now you have to answer him.
“Well… whatifIsuckedthemilkout?” you ask in a big breath. Dia squints at you,
“What did you say?” You clear your throat, avoiding eye contact by looking elsewhere in his room,
“I said, what if I sucked the milk out?” your voice cracks. You think death would be a relief right now with how embarrassed you are. Diavolo lets out a soft “oh”, and you turn back to look at him,
“I would like to try that,” he tells you, flushing like he’s got a fever.
“Yeah?” you squeak.
“Yes,” he nods his head to accentuate his point. You mumble out a soft, “ok” and lean down, glancing up at Diavolo, who gives you a reassuring smile, before closing your lips around his nipple. He moans when you first suck, or maybe you do, or maybe you both do. The flavor of his milk is sweet, not overwhelmingly sweet, but enough that makes you eagerly suck for more. Regardless of who moaned first, Dia is softly moaning now, his hands coming up to hold your head as you help relieve the aches that come with storing so much milk.
While sucking on his chest you have to focus serious energy into not getting an erection. You really don’t want to freak him out, but fuck this is so hot, and you know you’re going to (guiltily) jerk off thinking about this as soon as you’re able to.
Eventually the milk stops for a bit, so you pull back, kissing his puffy red nipple as you do.
“Is it-” Diavolo sounds breathless when he speaks, “is it good?” he asks, bringing his hands back down to the sheets. You let out a soft laugh,
“Yeah. I can’t believe you were wasting all this milk before,” you comment playfully. It’s only now that you’re not sucking at his chest that you notice something poking against you. Oh. Diavolo is hard. Your mind races trying to decide on whether or not it’s smart to point it out or not. Coming to the conclusion that things might end if you do, you simply turn your attention to his other nipple.
It’s wet with milk that’s been seeping out while you were suckling on the other, so you lave your tongue over the nipple, collecting the residue milk on your tongue, before engulfing it into your mouth. Now knowing that Dia is aroused by this as well, you focus more on drinking his milk than not getting hard. Speaking of Diavolo, he’s a mess under you, moaning, writhing, and arching his chest into your mouth. You look up from your spot at his chest to see his blissed out expression, his cheeks flushed a deep red, looking down at you, his lids lowered and pupils dilated.
“You-” he cuts himself off with a moan as you suck, “you look good,” he comments, biting his lip afterwards. Deciding to tease him just a bit you wink, and Dia laughs, bringing his hand up to cover his mouth. The laughing stops as he lets out another moan, hand still covering his mouth. And you can’t have that.
You pop off his nipple, “let me hear you,” your voice is rough with want. Dia obeys, dropping his hand as you return back to the job at hand. It’s not like he was holding back before, but with your command he gets even noisier.
The next time you pop off his chest is when the milk stops flowing onto your tongue. You give his nipple a kiss again as you pull back.
“Thank you,” Dia sighs, beaming up at you. You can’t help but smile back,
“My pleasure.” You can’t help but look down at the way his pants are tenting from his erection. “Need help with that too?” you ask playfully, but still wanting his consent. Dia giggles,
“Yes please,” the smile is wiped from his face when he feels you cup his cock, “oh,” he breathes out. You grope him over his pants for a bit, feeling him up and getting him comfortable with you touching him before you ask that he remove his pants. The two of you shift around so he can get them off, and when you see his dick you lick your lips. “I want to suck you off,” you tell him, running your finger from base to tip over his piercings. Dia shivers,
“I’d like that,” he confesses, and without any further ado you move yourself so you’re face to face with his cock. First you pull his foreskin down to reveal his head, giving the tip a quick kiss before taking it into your mouth and sucking, similar to how you suckled on his nipples not long ago. A spurt of pre hits the back of your throat when you take him down to the base, which surprises you. You suppose he’d gotten more worked up than you’d assumed when you were sucking on his swollen, puffy nipples.
Attempting to find what he likes best you bob your head a couple of times, fondling his balls as your throat constricts around his cock. The sensation of his piercings are a unique but not unwelcome feeling, and you vaguely wonder how they affect Diavolo’s pleasure. You then start to give special attention to his head, circling your tongue around and sucking at the pre that bubbles out. His hands grip your head, yet do not control your movement.
“‘M gonna cum,” he warns, bucking his hips a bit into your mouth. You bring your hands to his hips, holding him down as you take him to his base. Dia wails, cumming down your throat. A mantra of your name leaves his lips as you keep your head in place, swallowing around him as you drink down his cum. When he’s begging you to stop you pull off, licking your lips. Your cock is so hard it hurts, so you cup yourself softly, hoping you don’t call too much attention to yourself.
“May I help you as well?” he asks when he regains his composure. You grin, more than a little relieved that he wants to give you pleasure as well.
“And how do you want to help me, prince?” your voice is hoarse, but Dia doesn’t seem to mind.
“I’d like for you to fuck-” he pauses, worrying his lip a bit keeping you in suspense, “fuck my tits, please.” You groan at his words, your hips involuntarily jerking,
“Yeah? Shit, you’d let me? Fuck, please,” you babble excitedly.
While Dia shuffles around a bit, laying down further so you can mount him, you hastily (perhaps a bit desperately) remove your pants and underwear. You hover over his chest, lining your dick in between his pecs, then settling your weight when Diavolo guides you with his hands on your ass. When you squeeze his tits together a bit of leftover milk spills out; Dia whines softly at the feeling as you collect the milk as best as you can onto your fingers. You press them against his lips and he opens his mouth easily, letting you clean your fingers off with his mouth.
Your fingers come out coated in spit when you remove them from his mouth, so you wipe it off on your dick as a shitty, but workable lube. Again you squeeze his tits around your dick, thrusting between them slowly to adjust to the new sensation. You were surprised that Dia had cum so quick, but now that your cock is getting attention you don’t think you’ll last very long either. His chest is so soft around your dick, mix that with the way he’s looking at you with his lips slightly parted, his golden eyes flicking from your cock to your face, and he’s massaging your ass with his big warm hands. It has you panting and moaning in no time.
“Fuck, ‘m gonna cum,” you warn, to which Dia drops his mouth open and closes his eyes. That’s what pulls you over- because of course that would make you orgasm. Your cum paints his face as you fuck his tits through it. When you’re done he closes his mouth moaning as he swallows whatever landed there. You get off Diavolo’s chest, grabbing a tissue to clean off his face. He sits up, eyes closed as you sit crossed legged next to him, carefully removing your semen from him.
As soon as you’re done he opens his eyes to look at you and a noticeable silence fills the room. “I-” “My-” you both start at the same time, causing you both to giggle.
“You go first,” you insist, nervously fiddling with your hands.
“My lactation will continue for a few days longer, and, well, you did really help me…” he trails off suggestively, looking at you hopefully. You laugh, relieved,
“I take what we did was good then?” you ask, referring to everything that passed within the last few hours. Dia cocks his head to the side,
“If it were not I would have stopped you,” he says simply, then his eyes widen in recognition, reaching out to grab you, “oh tell me it was good for you as well? I didn’t overstep at any time, did I?” Dia worries sweetly. You shake your head,
“No of course not, like you I would have said something,” you flush a bit, “so, you want me to continue to help you with your milk?” Dia mimics your flush,
“Yes, if that’s alright.”
“Truly, it’d be my pleasure, prince,” you wink, making Diavolo giggle.
“May I ask you one last thing?” he asks, cheeks flushing and you nod. “Can I request a kiss?”
Your answer comes in the form of you cupping his cheek and kissing him lovingly. You’re glad your curiosity brought you here, because you truly feel like the cat who got the cream.
