A/N: Happy Birthday @vampcubus!!! I wrote this specifically for you bc I know you love ur vampires <3. Also, want to thank your amazing gf @renhoeku for encouraging me to make u this fic for ur birthday! You two are adorable. (also halfway into writing this I realized u may like vamp! reader more....but too late lol)

To be honest, dating a vampire was easier than one could imagine. Sure, he may be ten times stronger than you, and could kill you in a millisecond, but this was Tanjiro we are talking about, he tears up when he accidentally kills a fly. He was by far the gentlest person you have ever met, and it made it incredibly easy to fall for him.

Before he met you and early on in your relationship, he used to starve himself. Feeding once a week from stolen blood donation bags. It always made him feel horrible, but it was better than feeding off of an innocent. But still, with every gulp of the old room-temperature blood, he wondered what it would be like to drink straight from the source. The thought always made him shiver in delight, and he would have to force his thoughts away from it or else something could go seriously wrong.

But the thoughts seem to never leave his mind when he met you. He disguised himself for about three months into your relationship with much struggle. The scent of your blood drove him mad with need and the trips to the hospital grew more frequent. It was so unbelievably hard to take back the blood bags with you around. His fangs would protract whenever he got too excited, or when a drop of your blood spills.

He wanted it so desperately, and as he began to fall in love with you the need seemed to grow more and more. The staring of your neck would increase, and sometimes he caught himself salivating while running his fingers on the skin above your veins. He just wanted a drop of your blood, that’s all he needs and he won’t complain anymore. Just one drop.

It wasn't very hard to find out about his little secret. Day one, you met him you knew he was hiding something big, but couldn't put your finger on it. Slowly you've been studying him. The way he reacts to sunlight, not afraid necessarily, but obviously wary of it. He also is supposedly horrified of blood, but that doesn't explain why his face turns red, and you swear he had eyed you so strangely when you got a paper cut. And if he was so afraid of blood, why was he at blood drives so often?

You had your suspicions of him being a vampire, but he confirmed it without the use of words.

You found out his secret when you woke in the middle of the night to find him grinding on your leg, while his fangs lightly grazed the skin on your neck. He was obviously still half asleep, his eyes cloudy and half lidded. He was whining into your skin, and it was obvious that he wanted to latch down on your neck, but he was holding back.

When he saw that you caught him, he snaps awake and he seems to throw himself backward and away from you. His eyes widen with fear and he covers his mouth in an instant. He stares, panicked, in silence.

You blink at him in the dark. This confirmed it. “I-I knew I was right. You're a vampire. You have to be.”

He lets out a startled noise when you flick on your bedside light. His hands haven't moved from his mouth, but his eyes seem to dart around trying to think of an explanation on his strangely sharp teeth.

But the poor boy does not know how to lie. “Whatttt? No. Vampires? Th-Those aren't real!” The words are tight, and his body is stiff.

You raise your eyebrows. “Let me see your mouth.”

His eyes widen, and he scoots backward on the bed. “Just give me a second!”

“Now, Tanjiro.” You shoot him a glare, and he flinches. You sigh feeling slightly guilty from your tone. You were just a little shaken that your theory was possibly true. “I won’t be mad, upset, or scared. Just trust me. I just want to see them.”

He gulps and stares for a long second, clenching his fists on the sheets. He's nervous, it’s obvious. “Do you promise that you won't be scared?”

You smile at him, your eyes softening at his words. “It won't change anything, my love.”

He nods and slowly brings his hands down. A small gasp leaves your lips before you can stop it, and he slightly frowns. Hanging out of his mouth, and gently gnawing into his lower lip were needle sharp fangs.

He was pouting at you, afraid of your reaction, and continues to accidentally peirce his lip out of nerves. Small amounts of his own blood were coating his lip. In all honesty, he looked adorable.

But he was unintentionally hurting himself. You rush over to him and his eyes widen, but before he could protest, you lightly pull on his bottom lip. “Let it go. You are hurting yourself.”

He blinks at you, confused, but obeys and relaxes his jaw. His fangs now hang slightly in front of the pink flesh. “It's okay. I will heal.”

You nod at him, knowing this from your previous studies. “You really are one. A vampire.”

He looks away. “Yes I am. I'm sorry for lying to you.”

“Its alright. But Tanjiro,” You coax, and he glances at you, the slight pout still there. “The fangs are so cute.”

His eyes widen, and his face heats up. You watch the way he tries to hold back a smile from the praise. “Don't joke about that! They are deadly. I almost killed you!”

You smirk at him, leaning in closer to invade his personal space. He reacts immediately, not daring to make eye contact with you. “You wouldn't hurt a fly. You just want some blood right? You are hungry?” You pull your shirt down to expose more of your neck.

His eyes noticeably light up, and he gulps. He continues to stare at the spot on your neck, and his mouth slightly hangs open. His undergarments also seem to tighten at the prospect. The thought turned him on to an embarrassing amount.

When you catch the tent in his pants you giggle, and he immediately snaps out of the trance. He looks away with a red face and grips at the sheets. “No. I can't do that to you. I can't hurt you. I can wait till tomorrow to eat.”

It’s your turn to pout, throwing out the big guns. “Please? For mommy? I want you to be comfortable baby.”

He melts at the title and looks back at the strap on the nightstand. The two of you were only going at it three hours ago, it’s probably why he was so hungry. He lost so much energy from the multiple rounds.

“B-But…”

You scoot forward and rub your hand on his thigh. He shivers and grabs onto your hand for comfort. “Shhh, it will be fine. Should I get the strap? Maybe that will ease your worries.”

He wordlessly grabs the toy, and harness from the table and hands it to you. You pet his head with a smile and begin to attach it.

He removes his clothes and lays back on the pillows next to you, waiting for you to get ready. “I don't know if I will feed. I'm nervous I might hurt you.”

The idea sounds so perfect to him, but he is smart enough to not risk something like this.

You nod and position yourself above him, moving your hips to find his. He was already prepped considering earlier events.

You kiss his cheek and his ears turn red. “It's okay baby. You do what you want, yeah? Just going to make you feel good.”

The boy nods and covers his eyes with the back of his hands. “Mmkay…Mommy.”

You line up the tip, and slowly begin to press it in. He keens and grips onto you, slightly turning away so he isnt face to face with your neck. He really couldn't handle not sinking his teeth in if he was right next to it.

When you bottom out he lets out a breathless moan, and slightly arches his back. You pause to wait for him to get adjusted, and litter his red face with kisses. “Such a good boy. Taking it all, hmm?

He is visibly affected by the praise, nodding his head helplessly and pushing his hips back to try to signal you to move. You smile at this and begin your thrusting.

Today he seemed to slip into the subspace quicker than usual. You didn't mind, but it slightly confused you. Was it because the two of you already had previously fucked, or was it because he was hungry?

You secretly hoped it was the latter. The thought of how he would look with some blood in his system made u shiver in delight.

Not even ten minutes in, he begins his withering and clinging. “Doing so good for me. Does it feel good, baby?” You coo, while his fingers begin to leave scratch marks down your back.

“Mhm…Feels good, m-mommy. Harder please!” You chuckle at the plea and do as he says. His eyes roll back and his mouth hangs open, his fangs now completely exposed. He didn't seem to give a damn about retracting them. It must be a relief, he can completely get immersed in the experience without having to think about exposing himself to you. It further egged you on.

You lean your head forward and onto the pillow next to him. It was a tease, your neck exposed right in front of him, and both of you knew it. He has been trying to stay away from your neck, but you know he wants it desperately. The way he is literally salivating at the sight gives you more reason to spurr him on. He was too selfless. “N-No, cant!”

You pet his hair, “C’mon, I don’t mind. I know you want to, Tan.”

He moans at the words, his hands desperately pulling you closer. “But–I don’t wanna hurt you!” He cries, and you lick a stripe up his own neck to try to distract him from the ridiculous thought.

Drool is pooling at the corners of his lips, and his tongue roams over his fangs. He’s staring at your neck, eyes hazy with need.

“I know you won’t. Don’t feel bad, want you to eat. Please, for me?” He goes eerily quiet for the first time tonight, and you thought you took it too far. But a couple of seconds later, he whimpers with a small nod and shakily brings his lips up to your neck. He kisses and licks it at first, his mind going woozy at the smell of your blood. He looks at you one last time, and when you nod at him, he buries his teeth into your neck.

You cringe and bite back a whine, and Tanjiro moans into your neck. The sound was muffled but loud, almost desperate sounding. He flips the two of you over in a heartbeat with inhumane strength, now grinding on the strap while ravaging your neck. The sounds he lets are strange, almost animalistic sounding. A mix of whines groans, and whimpers vibrate on your skin.

“H-Hey, let’s get into a better position, sweetheart,” You say, the slight euphoria making your head dizzy. When he doesn’t move, you grip his hair and try to pull him back. He doesn’t budge, but he whines out at the interruption.

“N-No! Please, ‘s good, so good, please please please, mommy!” He begs into your neck, lapping at the dripping blood like a starved dog. It was endearing to see him like this. He was usually pretty composed, you have never seen him look so desperate. It was like he was waiting for this moment.

“Shh, I know. You can have more, let’s just get comfortable,” You reason and he nods into your neck, before hesitantly pulling away. His face is covered in blood, and his eyes are cloudy and unfocused. He licks at his lips and over his fangs, and to distract himself from latching back on to you, he focuses down on the strap, gripping at your hips and riding it more desperately than you’ve seen before.

You are quick to move but he is louder, already whining for your neck again. You swiftly put pillows behind you, and position yourself against the headboard, in a seated position with him on your lap. You grab at his hips and use the other to guide his head back to your neck. “There we go. All better now. Not too much, okay pretty?”

“Mhmkay,” He mumbles, still hazy-eyed and whiny. He latches onto the same spot again, and your eyes screw shut. You instead focus on his hips, helping him grind on the strap. His feet plant on the bed, and he uses them to help give him leverage to begin his own rapid movement on the toy.

You gently rub at his hair, petting him while he makes an abundance of adorable noises from both the force of the strap and the taste of you. “Wanted this so badly. Taste so good. Love it s-so much,” The vampire mumbles into your neck, kissing and suckling the skin around the source.

You smile, even if your vision slightly begins to blur from the loss of blood. Instead, you begin to focus on the way his thighs begin to tremble as he starts to bounce up on the toy. You grin, and he wraps his hands around your shoulders and neck, helping his movements become more intense. The toy seems to disappear within him at every bounce.

He's gotten to be a pro at riding. You remember how in the beginning he used to be so embarrassed, clinging onto you and waiting for you to thrust upward and into him. But now, he seems to be in his own world, lost in his pleasure completely to be embarrassed. The strange drunkenness from the blood certainly is helping him move quicker.

He begins to chant, “More. More. More.” into your neck with each passing second. Almost as if he was afraid that the supply would stop soon. You feel the heat of his breath on your neck, and you shiver.

After a couple more minutes, he willingly pulls away for the first time tonight. He stares at you, tongue hanging out to lick at the blood coated skin beneath him. His eyes are hazy, and seem to have little thoughts behind them. “May I cum mommy?”

You grab onto his untouched cock, and gently move your hands up and down the shaft. His head falls forward and onto your shoulder, where he tilts his head to stare at the bite marks. “So polite Tanjiro. Such a good boy for mommy, of course you can.”

His face heats up at the praise, and he shivers, but his eyes are locked on the fang marks on your neck. He wants more, but he can tell you are growing weak. It made him feel guilty how starved he seemed to be.

It wasn't his fault that your blood was better than anything he has had before. He has been dreaming about this moment for weeks now, and now that it was finally here in front of him, it was so hard to hold back.

You were making him feel so good, you didn't deserve to be overworked. But oh so desperately does he want to cum with his fangs in his neck. It would be so much better, so much more intense, he just knows it.

His eyes haven't left the spot on your neck, and it's gotten so bad that he has begun to drool again. The saliva of course is tainted with blood, so it slides quickly down his chin and onto his lap, staining his thighs red.

You can feel his gaze on your neck, and the way he slightly twitches. His movements don't seem to slow, but it’s obvious that he is having a hard time trying to fight his impulses. “You want more baby?”

His eyes screw shut and he shakes his head frantically, his bottom lip back in his mouth. “It’s okay! C-Can cum with–ahh–Out it!”

You grip at his hips, slightly smiling. “I know love, but you want to, right?”

Tears are now mixing with the drool and his head is spinning. He grips on to your hand like a lifeline, and continues to shake his head. “No. No. I don't–stop encouraging it mommy!”

He's looking out for you, but at the moment you don’t care. You want him to feel the best that he can so that he is more comfortable with feeding later. So, you ignore his request, and just like before you tug his hair forward.

His stained, wet lips come into contact with your neck and he moans at the scent. Your hands continue faster on his cock and he shivers. The drooling is getting worse, and he's beginning to make strange whimpering sounds as he tries to hold back. “Drink Tanjiro. I'm fine, really.”

He can't help it anymore. The voice of the rational side of himself is getting quieter and quieter every second he smells the blood. And now with your words? He bites into the flesh again and groans at the feeling of the warm liquid that seeps into his mouth.

He's licking and sucking at the flesh desperately, and honestly, it was strange to see your usual boyfriend so…feral. But of course, it was still him. His words proved through and through that he wasn’t really gone. “Sorry. Sorry. Sorry. I'm cumming. I'm sorry mommy!”

You slightly frown at the apologies, but instead focus on his orgasm, thrusting slightly upward, causing his eyes to roll back and tears to continue cascading down his face. His body tightens and he grips your neck possessively. A broken cry is released, and you feel his fangs drag upon your skin, only to let out a silent scream. The white liquid coats the both of your stomachs, and you play with his hair to help coax him through the high.

When he begins to relax, he isn't desperately pawing at your neck, but instead gently licking it to get the remaining drops, and hopefully helping you heal. When he pulls away to rest on your lap, your vision slightly blurs. “How are you feeling Tan?”

He grabs at your palm and nuzzles his face in it, the bottom half of his face stained red, but you’ve never seen him look so content. He seems to melt into your touch, glowing because he was now fed and had his orgasm. “Sooo good. Thank you so much. It tasted–” His half-lidded, lost eyes, fly open and he drops your hand. “Wait. How are you doing? Oh no, I drank too much. We need to get you some food!”

You lean forward to kiss him on his cheek and he touches it with a slight blush. “I'm fine. Just dizzy, and tired. I’m sorry love, I don’t think I can clean you up.”

He shakes his head, and scrambles off your lap, shivering when he feels the strap slide out. When he stands up to grab a wet rag you take notice of his shaking legs. It made you feel slightly bad, he was probably exhausted, but you couldn’t do much. You were equally if not more exhausted than he was.

When he catches your gaze, he smiles knowingly and leans down, and presses a kiss to your lips. “It’s fine mama, I’m okay. Go rest. I will take care of everything.”

But your eyes shut before he could finish his statement.

The next morning, you awake to find yourself dressed in your usual sleep attire, a bandage on your neck, and Tanjiro nowhere to be found. You frown at this, knowing he was probably still sore and tired.

But as on cue, he walks in with a plate of food. Meats, beans, and spinach. You raise your eyebrows at him. “They are rich with iron. Eating this will help you feel better from the loss of blood.”

The pounding of your head was gone, and you weren't dizzy at all. He was overreacting, worried over nothing, but that was who he is. But denying him would only make him worry more, so you take the plate and begin eating.

He sits next to you, kneeling while watching you eat. He looks determined to make sure you finish it. It was cute, really. “I'm sorry for last night. I went too far.”

You glance back at him. “It's okay. No, you didn't. Other than a small headache, I was completely fine.”

He lowers his eyes, and you see his cheeks begin to turn pink. “N-Next time I won’t–”

“Next time?”

He clutches at the sheets and peers over to you, his whole face now red. “Oh. We don't have to–It’s just it felt—It’s okay. Yeah, you're right–”

You throw a bean at him, and his nose scrunches. You laugh at him. “I'm teasing you. I don't mind having you feed off me. In a sexual or nonsexual way.”

His eyes seem to light up at the statement and he nods his head frantically, unconsciously leaning closer to you. “I would love that! I promise to be more composed next time and I definitely won’t drink as much!”

You fake pout at him. “Awh, but I thought your bloody and drool-covered face was quite cute.”

His face heats up, and he grabs onto your hand with a small whine of embarrassment.

You see the tips of his fangs peek out of his lip, obviously too distracted by your teasing words to retract them. It made you grin, and wonder how you managed to find someone like him.

Because who knew a vampire could be this cute?
