Chapter Text
It all starts with a harmless little cut. You were in the kitchen with Beel, cutting apples to bake a pie while he was rummaging through the fridge as usual, when the blade had sliced into your index finger.
“Fuck! Damn it...” You immediately drop the knife to hold your own hand, and sure enough you see blood starting to flow out of the little incision you’ve just made on your fingertip. Right on cue, the dull, burning pulsation of pain begins as well. You wince. It doesn’t seem too deep, but you definitely need to clean and bandage it. You start walking to the sink, reaching for the tap of cold water, when Beel unexpectedly stops you. You hadn’t even heard him come near you, but one second he was by the fridge, and the next he was holding your injured hand up to his face.
“Beel? What are you…”
You never bother to finish your question, not when what he’s about to do becomes so quickly obvious. His gaze is lit with pure, unadulterated desire as his mouth closes on your finger, gently trapping it between his teeth, and you feel his warm tongue slowly travel up and down your wound. The demon hums in delight, his eyes fluttering shut, and you feel your face heat up, too surprised to do anything but watch Beel’s expression, completely lost in the moment.
The tender caress of his tongue rapidly turns the light pain you were feeling into a warm sensation softly radiating from your hand to your chest, and as Beel’s gaze opens again to lock with yours, you suddenly feel like this strange yet simple moment is also perhaps the most erotic you’ve ever experienced in your life, despite everything else you had lived before coming to the Devildom.
After what could have been a few seconds or a real taste of eternity, Beel slowly lets go of your hand. You look at your finger, still in a daze, and you notice that even if the cut is still there, it has stopped bleeding. You look at Beel again, and you see his cheeks blush red.
“I’m sorry," he simply says, "I just couldn’t resist tasting you.”
“N– no it’s all right, you just… you just surprised me.”
You briefly excuse yourself to your room to look for what you need to bandage the little wound, and when you come back into the kitchen to finish baking your pie, Beel is gone. The fridge door is wide open, its contents emptied.
At dinner, while everyone eats the takeout from Hell’s Kitchen – Lucifer had sent you and Satan fetch it with a deep sigh after realizing that the house had yet again run out of food – you cannot help but steal what you hope are quick, discrete glances at Beel. You’re not sure if it’s because he noticed you or not, but you have the impression that he does as well.
A few days pass then, and you think that will be the end of it, but one day as you come home from RAD in the afternoon, you run into Beelzebub on the way back to your room. You try to be as casual as you can as he looks at you with that usual stone-faced expression of his.
“Oh! Hey Beel, what’s up?”
“Nothing much. But I need to talk to you about something, could you come with me to my room right now?”
“Oh. Err, sure? Lead the way.”
Beel and Belphie’s bedroom has a warm, pleasant vibe to it, but it does little to ease your nerves as Beel gestures for you to sit on his bed and then joins you, too close and yet too far at the same time. Ever since staying in his room, back when yours had been partially demolished along with the kitchen wall, you’d developed a crush on the gluttonous Sixth-Born. He was so big, and he had been very intimidating in his demon form, and yet he could also be so sweet and sincere. You’d often wondered how it would feel if he were to take your much smaller form into his arms for more than just a friendly hug. But he had seemed completely oblivious to your crush on him until now, which was why you couldn’t get the events of the kitchen out of your head, no matter how hard you had tried.
But then he starts speaking, and you’re pretty sure your heart skips a beat.
“I would really like to taste you again.”
Your mouth opens in surprise, but all you can manage to utter is a small, high-pitched gasp.
“Wait," he catches himself quickly, "that’s not how I wanted to say this. I… You… I haven’t been able to forget how your blood melted on my tongue. It’s… You’re really tasty. I don’t want to harm you, I won’t eat you I promise, but do you… would you be okay with sharing a bit more of your blood with me? I’ll only take just a bit.”
You stare at Beel, astonished. The rational part of your brain makes no hesitation in telling you all about how you should bolt out of his room and run away back to yours as fast as possible, but the heartfelt, pleading look in his eyes stops you. You cannot see anything wicked in his gentle purple gaze, it’s just the Beel you know.
And right now, he looks at you like you’re the most precious thing in the world.
“Beel, is… is my blood really all you want from me?”
Beel’s eyes widen, and then they fill with hope.
“No. It’s not all I want. I’ve wanted more for a long time now.”
His big hand comes to cup your cheek, its warmth sending delicious shivers down your spine, and his eyes close as he lowers his face to yours. His kiss is tender, his lips so delicate and smooth against your own. Slowly, he parts them with his tongue, and you sigh into his mouth, your eyes fluttering shut in delight. You lose all concept of time as he lowers you onto his bed, his hands caressing your hips, barely brushing against your breasts. And when he finally breaks the kiss, you’re not sure if you’ve ever felt such a mix of happiness and arousal before.
He gently takes hold of your arm then, his thumb tracing soft circles on the blue veins between your elbow and your wrist.
“Will you let me? Please? I promise it won’t hurt too much.”
You barely hesitate before nodding your head. Right now, you knew you wanted to share yourself with Beel, to give yourself to him this way and in so many others. The lust in his eyes intensifies, and he takes you into his arms as he rises to sit on his bed. You can feel his hardness press against your rear as he puts you sideways on his lap. He looks at you one last time for confirmation as he grips your forearm tighter. You nod again, trying to breathe to calm the maddening tremor of your heartbeat.
You see the nails on his fingers sharpen, becoming more akin to claws, and the one on his thumb delicately sinks into your flesh, tracing a moon-shaped cut in your skin. You whimper.
“That was the hardest part," Beel’s low voice whispers into your ear, "it’ll feel better soon.”
His warm mouth latches onto the bleeding wound and he sighs in delight as the first drops of your blood touch his tongue. He alternates between lapping at the cut, and then sucking on it, careful not to scrape you with his teeth, drawing every last bit of essence the shallowness of it is willing to give. Your head is lit with an exquisite fire. It had been painful at first, but now all you can feel is a delicious heat flowing from your limb to the rest of your body. You had never thought it could feel like this.
“Beel…” you moan, breathless. The arm embracing you tightens around your waist, and you can feel him shift under you as the hard length restrained only by his trousers rubs against you.
Finally, he stops, removing his face from your skin, panting. The cut is still there but it has stopped bleeding. You can see in his gaze how much the effort costs him, and you’re overwhelmed with affection as he turns to you and claims your mouth once more, his kiss more intense this time.
“Thank you. Thank you so much. You taste amazing, heavenly... I want to repay you, to make you feel how good it was to taste you. Please?”
You nod again, unsure what to expect, and you gasp when he lowers you on his bed once more and removes your bottoms and your panties, the most intimate place of you revealed to his eyes. He looks at you for confirmation again, and you give it to him.
“Yes… Beel, please, I’ve wanted this too… So much…”
His tongue delves into your slit, slowly flicking at your clit, and you moan. And as his ministrations become more and more passionate, as the wave of your orgasm reverberates in your core, you think that Beel is undoubtedly the best thing that has ever happened to you. The burning look in his eyes as he watches you come is as delicious as the caresses of his mouth.
You cuddle with him afterwards. You can clearly sense he’s still hard against you, and when he notices where you gaze wanders he chuckles and kisses your forehead.
“Don’t tempt me too much now, one thing at a time, okay? Let’s wait a bit.”
And so the weeks pass as you gradually come to hope for more with him. But that doesn’t mean Beel has left you alone, oh no. He comes back to you, almost every day, and soon enough the sensation of his claw sinking into your arm becomes a familiar prelude to your pleasure. Your blood in his mouth, and then his tongue on your wet heat. He tends to your wound every time afterwards, lovingly smoothing a thin cataplasm on the cut before bandaging it. It heals quicker thanks to the medicine, but still you start wearing long sleeved clothes more often now in order to avoid any sort of inquiry on why you somehow keep injuring your arm. You look forwards to those moments with Beel immensely. His ravenous passion, his captivated eyes, and the tenderness with which he cares for you afterwards. You daydream about it in class, so eager to feel his mouth on you again.
One day, as you’re both in Beel’s room once more, his twin busy napping in the attic, you see him shake his head when you offer him your arm.
“I want to try somewhere else today.”
“O–oh? Where?”
“The inside of your thigh. It’s fleshy, soft…”
He licks his lips, looking at that intimate area on the top of your leg. You think about him drinking from you there, and you feel your cheeks heat up.
“Okay, Beel. I trust you.”
He sighs in anticipation as you undress before him, leaving only the enticing lingerie you’d chosen for him on your body, and he wastes no time leaning between your legs and grabbing hold of your thigh, his claw tracing the usual moon-shaped pattern into your skin. You whimper as the blood starts flowing again, the pain more intense than usual. Maybe because he’d never cut you there before? The heat of his mouth soothes it all again though, and you relax, head rolling back as he laps at the cut.
It takes a while for it to register through your hazy mind, but at some point you feel like this is all lasting longer than usual. You also start to get a bit dizzy.
“…Beel?”
His hand comes to intertwine with yours, the comforting pressure of his fingers aiming to appease you. You hum and feel yourself calm down once more, but then a sharp, burning sensation on your skin makes you jump.
“Beel!”
Your reaction startles the demon and he raises his head to look at you. His lips are painted red with your blood. You look down at your thigh, and around a wider than usual cut you see four little round wounds. The marks of his top and bottom canines, you realize.
“Oh sorry," he says with surprised look on his face, "I got carried away… It really hurt that much? I tried to be gentle.”
“I– yeah it… The pain was more intense this time. Beel, you… you bit me. It… still hurts now.”
“Sorry, I should have asked. It’s just… I was lost in the moment. You taste so good, so good… And you’re so generous with me…”
He looks at your thigh again, his fingers stopping a few trickles of your blood before bringing them to his mouth to lick them.
“You’re still bleeding. I need to finish taking care of you. It won’t hurt anymore now, I promise.”
“O–okay. But please be gentle with me, all right?”
Taking care of you, as it turns out, means Beel dutifully cleaning your deeper than usual wounds with his tongue, sucking on every last one of them until the flow of your blood has run dry. Your head is spinning then, the sensation not unwelcome but still a bit scary. And when he brings you to orgasm again afterwards, you feel yourself drift to sleep as soon as he takes you in his arms when it’s over. Before falling asleep though, you hear his voice softly purring in your year.
“You’re so delicious, so kind… I’m so lucky to have you. Will you let me do this again, please? I promise it’ll hurt less the more we do it.”
The next day you think about his request, wondering if you should say yes. The whole situation has become a bit more… frightening than you’d expected. But still, you realize, you don’t want him to stop. Those moments you share together, and the wonderful complicity you now have in between, they’re the most precious things you have ever possessed. His smiles, his laughs, and the way he calls your name and engulfs you with his huge frame whenever he runs into you at RAD. You love him, and you think it’s also love you see into his eyes when he gazes at you adoringly after you’ve both pleasured each other, basking in the afterglow, even if he hasn’t let you unbutton his trousers yet.
It’s Beel you’re dealing with. He protects you, he cares about you deeply. He’s a demon, so he has a way of loving you that’s a bit different from humans, but that doesn’t mean you can’t trust him. So when you meet together the next night, you offer him your thigh again. Overjoyed, he accepts your gift, and this time the pain and the dizziness don’t scare you as much as they had the previous night.
When Asmo remarks on how you’ve been a bit paler than usual lately though, you realize that you need to space up your blood-sharing sessions. You explain it to Beel, telling him that humans need time to properly replenish their blood supply, and since he’s been taking more than usual, you also need to wait more than usual in between. He looks saddened by the thought, but he understands, letting you decide on how often you should both indulge. Giddy, you jump to wrap your arms around his neck, and he catches you and wraps your legs around his back, peppering your face and your neck with passionate kisses. You knew you’d been right to trust him. And really, it was all right if he nibbled a bit harder than usual on your thigh when it was time to offer yourself up again. The wounds were easily and safely hidden beneath your clothes this time, and the cataplasm he applied oh-so-tenderly on each of them afterwards did enough to not leave any marks, even if they did take longer to heal than the shallow scrapes he had left on your arm during the first few weeks.
Then one day, you’re on his bed again, indulging in another prelude before his bite, writhing in pleasure under him as he rubs two fingers around your clit with just the intensity he knows you crave. Feverish, you try to reach for his trousers, and surprisingly this time he doesn’t stop you. You gasp, feeling all hot in the face as you finally free his hard length from the confines of his pants. And holy hell…
“Beel… You’re… you’re huge! I…”
“It’s okay, we’ll take things slow, all right?”
You lie back down, and you shakily spread your legs open for him as he grabs his cock and rubs it against your entrance. Your delighted moans turn to a soft cry as he sinks the tip into you. He buries his face into your neck, grunting and licking your skin.
“You’re so tight," he whispers in your ear as he pushes himself further into you, "so small, so delicate… I love you, I love you so much. I’ll take care of you. Nobody will ever hurt you, I promise.”
His words soothe the dull ache you are feeling, and you melt into his embrace, welcoming him even deeper. And when, after an agonizing wait, he bottoms out, your moan is both of pain and delight, your eyes brimming with tears. Finally. Finally you were his, and he was yours.
“Beel, I love you too. I love you…”
He quickly ups the pace of his initially slow rhythm, as if, just like you, he’d been waiting too long for what he’d wanted to take from the start. His muscular back is so warm beneath your fingers, and you wrap your legs tighter around his huge frame, revelling in how small you are under him. He could easily crush you, you realize, but he would never, and you find that thought strangely arousing. It deepens the intense heat you are already experiencing, and you feel the familiar wave of pleasure rise within you.
“Beel! I’m going to… I’m going to…”
“Me too.” he growls into your throat, licking it up and down as he quickens his pace once more.
Your orgasm finally ripples through your entire being, overpowering you like no other, and in the midst of it you feel Beel’s hips stutter as he spills himself deep in you.
And that is when his fangs fully sink into the tender junction between your neck and your shoulder.
You scream. You scream like you’ve never screamed before in your life. Your voice breaks as Beel eagerly swallows the blood pouring into his mouth. He moans in delight, holding you tighter against him, his claws piercing the flesh of your arms in the process. You try to call out his name, but it is like the shrieking sound you’d just made had completely drained your voice, rendering you silent. Beneath the atrocious pain, you faintly realize how much of a grave mistake it had been to give in to his carnal thirst for you, to allow him to become so familiar with the taste of your blood. The taste of your life flowing out of you…
The world blurs around you, and you vaguely hear a door slam open. You think you can hear Belphie’s voice near, screaming at his twin to stop. To let go.
Soon, the sound of other multiple footsteps and shouts start fading into nothingness, and your eyes close as your head spins too much for you to remain conscious.
***
You don’t see Beel for a while after that. Not when you are unable to leave your bed for so long. His six brothers visit you often, just like Simeon who spends long moments by your side, softly chanting as his hands emit a golden glow against your skin, slowly mending your wounds and helping with your blood loss day by day.
It’s Belphegor who talks to you the most. He tells you everything about how Beel just hadn’t realized, how he’d been so careful with you for so long and had simply underestimated how fast his control could slip when he was melting into bliss with you.
“You have to forgive him,” he says, “he feels so guilty. He’s dying to hold you, but he won’t. He’s afraid you’ll fear him now. Please, you have to ask Lucifer to let Beel see you.”
Eventually, when you feel your strength returning, you agree. You beg Lucifer, and he finally relents with a deep sigh, calling for his brother. And when you see Beelzebub’s huge frame fill your doorstep, his eyes brimming with tears, you feel your own eyes water.
“I’m so sorry…" he says. "So sorry… I didn’t want to hurt you. I just thought… I just thought it’d be okay. I don’t… I didn’t realize how bad it’d be. I didn’t think…”
“It’s okay, Beel. It’s okay. I know. I know…”
You hope he’s telling the truth. You hope that, instead of giving into temptation that day in the kitchen, and again when he’d brought you into his bedroom, all the while knowing full well where all of it would lead him, he truly didn’t know.
You forgive him. You forgive him and you heal. The marks of his teeth on your neck fading completely thanks to Simeon’s holy magic. Slowly, things start becoming the same again. He never asks to drink from you anymore, and it takes him a long time to even think about sating his own pleasure when you feel comfortable sharing your body intimately with him again. For a long, long while it’s just about you, about erasing the memory of the pain he’d caused you, replacing it with ecstasy. Over and over again. And finally, when he gives in to your pleading and makes love to you again, he’s slow and sweet, gentler than you could ever imagine someone being.
All is well.
Or, at least, all is well for you.
It’s something you are unable to hear about, of course. Not while you’re down here in the Devildom. But after you start spending time around Beel again, Lucifer calls him into his study, unbeknownst to you. They talk for a long time, and when Beel finally leaves, it’s with a seal. A special kind of seal granting him a regular access to the human world.
Humans start going missing, then. Every week, a new one disappears. When you and Beel start making love again, the number goes up to three a week for a long time. They all either have your eyes, or your hair, the curve of your hips, the shape of your smile, a scent vaguely familiar to yours… In one way or another, they all look like you.
You’ll never find out of course, probably not even when you’ll end up going back to the human world again. After all, people just vanish without a trace every day, it’s common occurrence. It’s hard to truly figure out what could have happened to them anyway, especially when there’s nothing left to find.
