Waking up alone wasn’t abnormal, but usually the bed would be warm still and this morning it wasn’t- which constituted a major problem. Your auburn haired prince was not in bed, and based on how cold his side of the bed was you could tell that he had been out of bed for a while. That was, if he had even come to bed at all during the night.

And today was his birthday, which was supposed to be a day for him to be celebrated and not drown himself in paperwork. He wouldn’t even enjoy the day if he was exhausted, and that’s the thought that has you sliding from the large bed in search of your sweet prince.

You don’t have to look far; the door to his study is cracked open and soft music is coming from the room, telling you that he was definitely in there working, instead of anything truly fun. The sight of him hunched over the desk, pen furiously scribbling away in his notebook while surrounded by stacks of paper taller than you were, was pretty depressing.

“Did you go to sleep at all, birthday boy?” you ask as you shut the door to his study behind you, bringing his attention up from the papers for only a moment to take you in before he’s looking back down.

“I got some rest.”

“A fifteen minute nap in your chair isn’t rest, Diavolo,” you argue, coming to stand behind his chair and placing your hands on his shoulders. They were so tense, you hate how much stress he carried at all times. He didn’t deserve that at all. “At this rate you’ll kill yourself before you fully take the throne.”

“You sound like Barbatos, my love.”

“That’s how you know it’s a good point.”

“Maybe so,” he murmurs around a sigh, looking up over his shoulder to see you looking down at him with a concerned frown. “I left you all alone in that big bed, I’m sorry.”

“You had a lot to do, I get it.” And you do, even if you will never fully understand the position he’s in. He’s doing this because he feels he has to, considering the massive shoes he has to fill, and you can respect the effort even if you don’t like it. “But you need to take a break, baby. I’m sure Barbatos is up, maybe he can fix you some tea. I’ll go-“

“No, please stay here with me. I’d like to make up for leaving you high and dry last night.”

“You’re busy.”

“I need a break.” He counters while pulling you around to stand in front of him. You looked so cute in his nightshirt, better than he did in the silky garment, and he knew you weren’t wearing anything underneath by how your nipples poked through in the chilled air of his study. Another careful pull of your hand has you off balance enough that he could guide you to straddle his thigh easily, and the warmth of your arousal that he felt through his slacks makes him smile as you steady yourself using his shoulders.

“I’d like for you to use me to get yourself off. I’m all yours.”

“I’m saving your cock for later, then. You can have your present later if right now is about me.”

“You’re the greatest gift I could ask for,” he whispers, smiling when you kiss him as your hips begin their slow work of riding his thigh. It would be a wonderful start to the day, but you were definitely going to find more time for him to get some breaks during the day.

He doesn’t even make it to lunchtime before he’s dozing off. Not that anyone would say something bad about the future Demon King falling asleep during a class on curses, especially not on his birthday, but you certainly had plenty to say and intended to do so when he guided you into the Student Council chambers under the guise of needing to talk to you about "official business".

“You need to go home and rest, Diavolo.” Comes out of your mouth before he’s got the chance to say anything, and you watch as he slumps into the chair that was normally occupied by Lucifer during meetings. “You never fall asleep during class.”

“I was actually hoping you’d let me have you excused from the rest of your classes to help with some paperwork from the House of Lords.” That wasn’t what you wanted to hear, and the way you cross your arms over your chest makes him sigh tiredly while running a hand through his hair. “Please.”

“Can’t any of this wait until after the Devildom holiday that is Prince Diavolo’s birthday?”

“It’s not a holiday.”

“It is to me.” You hop onto the long table, your eyes fixed on his as he watches you. He was more interested in your skirt than your face, but you did tuck your panties behind the pocket square in his breast pocket before class started so you knew he was most interested in the fact that you weren’t wearing any underwear. “You should’ve just canceled classes, it’s not like you'll be awake for the rest of them, anyway.”

“We take a break now, you help me with these papers, and then during the last class hour I promise to take a nap.”

“Pinky promise?” Your extended hand curls so only your pinky finger is held in front of him, a playful grin on your face as he lets out a laugh of his own. The little things you brought to him from the human world never failed to amaze and amuse him, and pinky promises always brought some light to his day. “You can’t break a pinky promise.”

“I never would,” he assures, locking his pinky around your own and bringing your joined digits to his lips to kiss them. “May I ask why your panties were that wet, princess?”

“Was just thinking about you and how handsome you are and how I could reward you for all your hard work. It is your birthday, after all.”

“I have an idea, if you’re open to it here.” He’s palming himself through his trousers, the bulge there already prominent as he watches you watch him. “I’m already so hard it hurts.”

“And why, dear prince, is that the case?”

“You, my love. Only ever and always you.” He’s such a romantic, carefully helping you off of the table only to pout when you don’t follow his prompting to get onto his lap. That could wait, and you know that he knows what’s on your mind once you’re slowly lowering to your knees between his spread legs. “You spoil me.”

“It’s your day to be spoiled.” He undoes the fastenings of his pants for you, and you know your eyes light up when his erection springs to life once it's been freed from its confinements. The chamber doors don’t lock, which provides a bit of risk to the situation at hand but you also know that only two people would willingly walk into the Student Council chambers without there being a meeting called and both Lucifer would immediately turn around and leave at the sight of you leaving a trail of kisses along the cock of the Prince of the Devildom. Barbatos would handle whatever business needed handling, then leave with a pat to both your heads and reassurance that he’d keep everyone else out until you both were ready to be around others.

You wish you could take a picture of how pretty Diavolo looks when you’re sucking him off. How he’d watch with adoration as you took every bit of him that you could into your mouth and throat, how he liked to look you in the eyes and tell you how wonderfully made for him that you were that you could take him so well with minimal struggle. How even when he was keeping your head down on his shaft until you needed him to let you up to breathe, the look on his face is one of pure adoration and reverence as he takes you in.

“Please, I’d like to cum inside you. Let you carry me with you for the rest of the day, then after the party I can fill you again.”

“Are you going to come to bed tonight?” you ask, raising an eyebrow when he gives you a nervous smile. “I’m not going to let you fuck me after your birthday party if we’re not sleeping together tonight. And you deserve a full night of rest.”

What you get in return is his pinky extended towards you, and you lock yours around his as you stand.

“I promise, my love, that I will come to bed tonight and sleep with you through the night. Not leaving until you do.”

“Pinky promises hit a bit different with your dick out, prince charming.” He laughs, but still kisses your joined fingers when you lean in to do the same, his free hand coming to you back to push you into him. You’re grateful you opted for the skirt today instead of pants, allowing for no restriction to stop you from lining his tip up with your already dripping entrance.

“You’re already so wet for me. Does sucking me off get you going that much?”

“You have no idea. You’re so fucking pretty, birthday boy,” you comment as you sink down onto his length, carefully nipping at his bottom lip when he grins at you. “My pretty prince.”

“And you’re my beautiful princess, the sweetest girl in the three worlds.” You both release a mutual sigh of pleasured relief when you’re fully seated on his length. “Stay for a moment, please.”

“As long as you’d like.”

“I think I’ll take tomorrow off,” he murmurs, his thumb coming to rest on your clit and rubbing lazy circles that have your walls fluttering around him. “Keep you in bed with me all day, just like this. Maybe we can read a little, listen to some records, but this is what I know I need.”

“Cockwarming?”

“You.” The correction comes with a kiss, and you’re smiling against his lips as you start to ride him. Your pace is easy, slow and careful considering you have very little to worry about. Sound didn’t escape this room, so nobody would hear your prince when he started to get loud and come investigating. “Fuck, just you.”

Your hand finds itself on the back of his head, fingers interwoven in the soft auburn locks as he kisses along your jawline while your hips roll into his. And he’s talking, tired babbles whispering to you how much he loves you, how wonderful you are, how good you feel, how badly he can’t wait to do this all over again all day tomorrow until he has to stop. Your stamina wasn’t the same as his, considering your difference in biology, and that was something that he had to learn the hard way to keep in mind as he fucks you.

“Fuck, princess,” he groans, pressing his face into the crook of your neck as the grip on your hips grew tighter. He’s no longer letting you simply ride him, now rocking his hips up into yours to meet your pace. “Gonna cum for me? Gonna cum so I can fill you with mine?”

You can only nod, your own hand tightening in his hair to keep him close while he fucks up into you. You can hear the chair’s groans of protest to the frantic movements happening, barely registering Diavolo’s desperate babbles into your skin, and you know that you’re talking but you can’t hear the words tumbling from your lips into his shoulder as the coil in your gut continues to tighten.

“That’s it, princess. You can do it, please cum for me.” His mumbles into your neck only push you closer, your heart pounding and blood rushing through your ears the only thing that you could focus on as your legs tighten around his hips. You’re pressing your face into his neck when that coil finally snaps, your knees digging into his thighs as his hips still against yours and you feel the heat that came with Diavolo’s cum releasing inside you.

“Feel better?” you ask once you’ve caught your breath, kissing his jaw before pulling back to steal a peck at his lips. The dazed look in his eyes tells you everything you need to know, followed by a soft purr when you carefully scratch at the back of his head. Your sweet prince needed this time to simply breathe, and you’re happy to provide that for him.

“So much better.” Is all he says once he’s recovered, a dopey smile on his face before he kisses you. This kiss is just as sweet, but the laziness of it provides you with great pride in knowing that he was truly relaxed in this moment. There wasn’t a rush to give you what you were looking for before he could get back to his work, no desperate hunger fueled by distance or his need for distance so he could get work done in peace. It was just you and Diavolo, relaxed and satisfied together in this moment. “I really, really love you princess.”

“I love you, too. Now put your dick away, Diavolo,” you prompt, gently ruffling his hair as you remove yourself from him and the chair and straighten your skirt. “And get out of Lucifer’s chair before he learns that we fucked in his seat.”

“I’ll call Barbatos and ask him to bring us some lunch.”

“You’re the best. Now where can I help with this mountain of paperwork so you can shut your eyes for at least fifteen minutes?”
