An Altar For Our Sins
Part 6 // Masterlist
Demon!Billy Russo x Reader
Warnings: Dark!Billy Russo, minor talks of non-consensual acts done in part 5, smut, oral (f and m receiving), fingering, face sitting, tail fucking, (putting that in bold so you see it), you hear me? He fucks her with his tail. It's consensual. Do not complain to me if you miss these warnings. She sort of gets a little high at the end from his cum. Mentions of blood and violence similar to other parts.
Tumblr media
You'd let it bother for quite some while. Ever since he confessesed it to you, you went through many confusing emotions. Shock, worry, arousal, confusion, more arousal, concern, and then acceptance.
Now, you were onto another emotion entirely.
Fury.
As you watch him, deep in thought, pondering your next logical move after the events of today, you finally decide to say something about it.
"I think I'm mad at you."
He pauses, turning to look at you with widening eyes from his spot, leaning against your dining table. He almost looks innocent, with the way he blinks once, his eyebrows furrowing immediately after.
"Mistress?" He asked with a concerned voice and your glare doesn't waver.
"You cleaned me up while I was asleep, Billy... with your tongue."
You can see the genuine confusion and concern in his eyes.
"Yes?"
Damn, you were so aroused already. You take a few steps toward him, looking up at him angrily.
"You used your tongue on me, your rough, perfect tongue on me, while I was asleep- do you see the problem?"
His eyebrows draw together just a little, deep in thought.
"I-"
"You didn't think I'd want to be awake for that, Billy? Hmm? Didn't think I'd prefer to feel it? What if I did that to you? What if I licked that big cock while you were asleep and told you all about it when you woke up? How would you feel?"
Billy gulps.
"I'm sorry?" He mumbles, eyes trailing after you as you turn away from him with a scoff.
"I can make it up to you." He offers, watching your retreating form, his stomach clenched with the need to make things right.
You sigh, "Yeah, but I won't know if you're genuine or not- there's nothing quite like the first."
"Mistress." He says, desperately.
You turn back to face him. He takes the few steps it requires to stand before you. He looms over you so easily, your stomach flips at the size of him.
When he drops to his knees, you struggle with your arousal to stay composed, though it takes everything in you not to crumble.
He takes your hands in his, looking up at you with pleading eyes and you're so eternally turned on.
"Let me make this right," he begs, kissing your fingers, "Please, I can do better."
The power he gives you, goes to your head all over again. It's just like that night, the way you want to torment him burns inside you. You raise your hands to cup his face, your thumb brushing his lips.
"Poor little demon," you whisper, watching his eyelids flutter at the words, "Wants to make his mistress happy so badly."
His eyes flicker red for a moment.
You straighten your body.
"I suppose why not? It's not like you haven't already had your taste of me." You speculate, turning away from him to head to your bedroom.
.

EARLIER TODAY:
"You're being followed."
You tense up, fighting the urge to look around.
Was it the same people that had kidnapped you? Hadn't Billy confessed to killing them all? Maybe it was just some random person that had taken an interest in you.
You try to keep walking calmly, Billy's hand pressed to your back to steer you.
After a moment, you build up the courage to speak.
"What's going on?" You ask him, raising a hand to your mouth to pretend to yawn while you speak.
Billy looks around for a moment.
"Got a sense that something was off, noticed there's a car that has been following you for a couple of blocks, and three people on foot behind us that are suspicious- here- just stop to look at this flower for a second."
You do as he says, pausing to look at the bouquets lined up outside of the store.
"Oh, they are pretty." You say, distracted by the combination of sunflowers and roses.
"Yeah, they're definitely following, bad job at it too. Come on." Billy says, hand pressing into your back to guide you along.
You turn, and continue down the street.
"Where are we going?" You ask, curiously.
"There's a church nearby, you'll be safe there while I find out more. No one will think to look for you in a church if they think you're bound to me."
"Why?"
"Cause they think I can't enter. Turn here, I'll make you invisible until you go in, call for me if anything happens."
You swallow, hesitating to leave him. Your body takes on a purple aura, letting you know that you're invisible. You head up the steps to the small church, the large wooden door makes a solid sound as it closes behind you.
And then you're alone.
You swallow, studying the carving on the door. The church is so silent compared to the street outside and it emphasises how alone you are.
You turn, there's no one around you can see, but the atmosphere of the church distracts you. You study the beautiful stained glass mural at the front, light shines through, tossing a kaleidoscope of colours into the air.
The calm hush of the room calls to you, quietly asking for you to respect the space you're in.
You're entranced by the detailed design, everywhere you focus you find so much carefully thought out devotion expressed as art.
Carved marble columns, religious paintings lined with gold, you wonder how much time and effort had been put into the place.
And then you remember that Billy's existence implied there was one of higher power.
It doesn't necessarily change the way you see the world, it's not some big epiphany that comes with the realisation that God was real.
It did make you wonder about both sets of your parents.
You hadn't known your biological parents well, but you wondered where they were. Was there a heaven for them? Had they already faced judgment?
The thought makes you frown, a searing pain in your chest and the idea that you would face a similar judgement one day.
Then your adoptive parents come to mind. People who had taken you in and raised you as their own couldn't have possibly been bad enough to deserve hell right? They'd been atheist, did that automatically condemn them? Was that fair?
"I can tell you're spiralling." A voice says behind you.
You spin in fright, to find a man with a very kind face smiling at you. He raises his arms in a surrendering motion when he realises he's scared you.
He's dressed in a cassock and collar, with a shiny black rosary around his neck, a pair of red tinted round glasses sit on his nose, so darkly tinted that you wonder how he can see anything through them.
"Didn't mean to scare you," he says, "I just have a sixth sense for existential crises." He smiles.
He's very hot, you decide, with hair neatly combed on his head, and a short cropped beard, you find yourself returning his smile.
"Sorry, yeah, I just came to the realisation that God exists." You say, nodding your head in the direction of a wooden carving of Jesus on the cross.
He hums, "Well then, welcome to the club."
His words are so odd that you can't help the laughter that spills past your lips, and then you find him smiling along with you, proud that he'd lightened the mood.
"I'm Matt." He says, extending a hand to you.
"Matt? Not 'Father' or anything?" You ask curiously. You find yourself studying him closely, realising that there are some healing bruises on his cheek, and a split lip that looks to be a few days old.
"'Father' is so formal. Matt is better."
You nod, giving him your name and reaching out to shake his hand.
"Are you okay? You look like you lost a fight." You ask, concerned.
Matt smiles, waves off your concern.
"Ah, not being able to see sometimes means you fall down stairs. I'll be okay."
"Oh, I'm sorry." You say in sympathy.
"About the stairs or the blindness?" He asks with a humorous inflection in his voice.
"Are all priests this funny?" You ask with a wide smile, and he chuckles.
"I'm just trying to make you feel better, I know how confusing things can be for you right now."
You let out a sigh, nodding.
"I appreciate it. Life has been a big mess as of late... but not all bad." You turn to study the rows of flickering candles nearby.
"I imagine being soul bonded to a demon can't be all fun." He answers and it takes you a second to realise what he's said.
You turn slowly this time, mouth open comically. He keeps a kind smile on his face while you quietly lose your shit.
"What do you mean?" You say, playing dumb.
He bows his head, to hide his smile.
"Cards on the table, I can sense demonic auras. But I've never met a living person with a demonic aura, so I put two and two together and figure that you must have been bound to one... I assume against your will. Am I correct?"
"Y- yeah..."
He nods, deep in thought.
"I'm not judging. I'm in no place to do that. Though I hope you're okay, and I want you to know that if you ever need any help... I won't turn you away."
You blink at him. Was it really that easy not to judge someone?
"You're not... condemning me for it?" You murmur in a soft voice.
"Don't get me wrong, it's not something I support... but you don't seem like a bad person, just an unfortunate circumstance."
You swallow the lump forming in your throat, nodding, feeling the urge to make him understand.
"You're right. I didn't want this. They tried to sacrifice me... he saved me. He keeps me safe."
Matt nods in understanding.
"Please be careful though, manipulation is in their nature."
You blink, your head trying to come up with a myriad of excuses for Billy, a way to explain to this knowledgeable stranger that for all Billy was bad, he was working to be better.
As you open your mouth to explain, the church doors open.
It's hard to see more than his silhouette with the brightness of the sun behind him, but you know by the horns, that it's your demon at the church doors.
"I have to go." You say to Matt, turning back to him.
He inclines his head.
"Be careful." He says, before turning away, and disappearing into a room to the left of the altar.
You think about the strange conversation as you head toward Billy.
When you get close enough to make out his features, your mouth drops open in surprise.
He stands in the light of the church doors,  drenched in blood.
"What the hell happened?!" You whisper aggressively to him.
All he does is give you a bloody grin.
Water pours over both of you.
You're still fully clothed, but you take your time helping him out of his bloody shirt.
Blood runs in rivulets from the crown of his head, down the sides of his face and over his torso.
He's deliciously attractive like this, and you try not to let it show as you help clean him.
Just moments ago, you were standing in a church corridor, Billy had wrapped his arms around you and teleported you right into your bathroom.
"Whose blood is this?" You ask, grabbing some shampoo to work into his hair.
He bends his large body, presenting the top of his head to be cleaned.
You take your time, working the shampoo in, lathering easily, and rinsing the blood from his hair. Out of precaution, you give him a second wash too, making sure to get every inch of his horns. He groans once or twice when you use your nails to scratch along his scalp, not paying it much mind.
"The group that summoned me is a lot bigger than I thought." He starts, as you work conditioner into his hair.
"Some of them had been watching from cameras that night, and they'd seen everything happen." Billy continues to explain.
You take a deep breath to steady yourself.
"They know where you live, but they wouldn't dare try something, not with me here."
"Should we move? Just in case?" You ask. Your little apartment definitely wasn't the safest place to be, and if it made you feel safer, you wouldn't mind getting a place with better security on Billy's influence.
He thinks about it, and after a minute, he nods in agreement.
You think about what they could have seen- you, sobbing and bound, wearing your coat and nightdress, the way you'd tried to crawl away, the way Billy had looked, naked and shrouded in smoke.
What would they do if they managed to catch you? The thoughts were terrifying.
"Hey." He says, bumping his horn into your hand to get your attention.
He raises his head, and you gulp as he towers over you.
You know what he sees, your worried expression, you wonder if he can feel the nervous wriggle of your stomach, the way you're trying your hardest not to freak out.
"I-" You try to tell him that you'll be okay but the words won't come. You look away, avoiding his eyes.
"Mistress." Billy murmurs softly.
You look back at him, his hands raise to cup your face.
"You're safe, I promise you that you're safe."
You swallow, nodding.
A warm moment as he bumps his nose against yours, leaning in to place a soft kiss on your lips.
.
.
.
NOW:
You're sitting on the bed patiently when he walks in. Though you were confident only moments before, you've gone shy now, with the realisation of what you're about to do.
Slowly, looking up at him you tug your shorts down your legs, letting him see the comfortable, white silk panties just below.
He moves closer, eyes still fixed on yours as your thumbs curl into the waistband of your underwear next.
He leans forward to stop you, his large hands covering yours, pulling them away.
"Why don't you lay back, and let me take care of everything?" Billy offers with a soft voice, and you nod, looking up at him.
You take a breath, scooching back on your bed, propping your head onto a stack of pillows that has you reclined at a 45 degree angle.
He gives you a warm look of approval, before reaching back to pull his shirt over his head.
His hair gets messy, and you fight the urge to right it, his horns poking through his hair.
You swallow, eyes trailing down his bare torso, carefully sculpted, beautifully carved, leading down to a small waist.
He's built a little like a swimmer, you think, defined in all the best places.
His knees touch the bed, you press your thighs together tightly as he crawls his way up to you. A predator in every sense of the word.
He hovers over you, large and imposing, with warm eyes and a gentle smile.
"Sure you want this?" He asks softly.
You struggle to open your mouth to speak, only able to nod eagerly.
"What are you going to do to me?" You whisper, watching his eyes dart down to your mouth.
He lets out a long sigh, eyes sparkling red for just a moment before he speaks.
"I'm gonna get you nice and naked." He breathes, "Gonna kiss your pretty skin until you're so relaxed under me that you can barely lift your head." He leans in to whisper the rest into your ear, his soft stubble scratching your skin gently, your core throbs in response to him.
"Then, I'll put my tongue on you. Lick that sweet cunt until you're crying, until you're not sure if you want to pull me closer or push me away."
He draws back so you can look into his eyes. There a place, set between your hip bones, that tingles deep inside of you.
"What about your fingers? Or your tail?" You ask.
"What about them?"
You swallow.
"A-are you going to use them on me?"
His smile grows into a grin.
"No." He murmurs, leaning forward to kiss the tip of your nose.
"If you want that, you're going to have to ask for it. I'm not going to fuck my tail into you without your consent." He says. The tail in question trails gently over your thigh.
Oh? Now he's concerned about your consent?
You nod in understanding, raising a hand to cup his cheek. He lets out a slow sigh, closing his eyes, savouring the feelings in his chest.
Your hand drifts, cupping the back of his neck and he opens his eyes to meet yours.
You pull him closer, you brace your other hand on the bed to push your face closer to his.
When your lips meet, it's surprisingly gentle, despite the fact that you can cut the desire in the room with a knife.
Your first kiss with Billy, your real first kiss and it's perfect, he doesn't treat it like a preamble to anything else, doesn't rush to pull at your clothes or feel your body while you're distracted. No, he cups your cheeks to keep you in place, no chance of you slipping away or breaking the kiss before he's ready.
He sighs against your mouth and you desperately take the opportunity, parting your lips to run your tongue over the seam of his.
He groans, his hands tighten on your face for just a second, before his mouth parts, eager to slip his tongue against yours.
You make a small sound of delight, his tongue just a little rougher than normal, tangling with yours in the best way, a sharing of your breaths that feels more intimate than anything else.
Your hand drifts higher, into his hair, all the way to the lovely dark horns sprouting from his head.
From the first graze of your fingertips against his horn, he lets out a long groan, the sound vibrates against your lips, desperate and brazen and begging you.
It's you that has to finally move, slipping your hand from his hair, grabbing one of his hands that cup your cheeks and guiding them down to the edge of your shirt.
His fingers curl around the fabric absentmindedly, moving only the way your hand guides.
You push his hand up one side, until the shirt can go as far as possible, and then you reach for the other side of your shirt.
He breaks the kiss finally when the shirt is tucked under your breasts, his other hand moves from your cheek to where your hand is, pulling your shirt up, and off your body.
The air kisses your cool skin and you can't help but shiver.
You're bare beneath it, and you watch Billy's eyes shine red, tucking the edge of his bottom lip into his mouth to bite down on it.
You reach up, smiling as you use your thumb to untuck his lip, leaning forward to bite down on it yourself.
The sound he makes is downright unhinged. You almost giggle and if you weren't nibbling on his bottom lip you definitely would.
He pulls back, letting his lip slip from between your teeth, pushing you until you fall back against the pillows with wide eyes.
He kisses your lips one last time, then the corner of your mouth, over your cheek, the edge of your jaw to the spot right below your ear.
"Let's not forget why we're here, Mistress," he says into your ear, his tongue slipping out to graze the shell of your ear. You gasp in surprise at the pleasurable feel, "My tongue."
How could you forget? It's not as if you could stop thinking about his tongue from the moment you licked over it a few nights ago.
He kisses down the column of your neck, before taking his time, licking all the way up.
God, that feels so nice, the ache between your legs can no longer be sated from being pressed together. You wriggle, and he leans back to give you the space you need to wrap your legs around his hips.
Your ankles lock behind his ass instinctively, and when he smiles, leaning back in to continue his exploration of your chest, you feel his stiff erection right against your centre.
You gasp, rocking your hips a little, chasing the feeling that grinding your clothed pussy against him gives you. You wriggle, whining when the pressure isn't exactly in the right spot, only to feel his tail, work its way between your thighs to press right against your clit.
You gasp, body arching at the pleasure that fills you. His tail making micro movements against the gusset of your panties, relieving the ache.
You relax, sighing as his tail sates you for the moment, his lips resuming their careful exploration, kissing over your chest, followed by the swipe of his tongue over your skin.
He gets to your breasts, kissing them softly, suckling the stiff bud of one breast between his lips before switching to the other.
He's so gentle, you feel a pull low in your stomach, begging him to just take you.
Fuck, if he was smaller, you'd be begging for him to try, but as of right now, you were still daunted by the size of the erection pressed against your thighs.
His hands push your breasts together and you groan, with his tail rubbing over your slit and his rough tongue dancing over your nipples and you feel just about ready to cum.
"Billlyyyy." You sing his name, he chuckles against the soft skin of your breast.
"Mistress," he murmurs, "I'd appreciate your patience while I explore your body. It's not every day that one gets to explore his willing charge."
You groan as his tongue snakes from your nipple to your neck.
"You're being mean." You gasp out, one hand drifting up into his hair.
"I know. Isn't it fun?"
You let out an exasperated breath.
He continues kissing over your skin eagerly.
You let the need take control of you, reaching up to grip one of his horns, you pull him up for an eager kiss, putting all your feverish need into it.
He makes a sound, one of surprise and disapproval of interrupting his exploration.
"Please, please, please." You murmur hotly against his mouth, licking over his lips and feeling his tail press more firmly down on your clit in response.
"Stop teasing me." You beg finally before pulling away.
"Or what?" Billy challenges and you finally understand how truly demonic he can be to you.
But maybe you had a little bit of torment inside you too.
"Or I'll get someone else to do it." You hit back.
When his eyes flash red this time, you know it's anger and not lust. His jaw clenches, he takes a sharp breath. He lets some of the anger out on his next exhale.
His eyes remain red, as his mouth turns up into a smile.
"You're adorable, mistress." He say, leaning in to speak right into your ear in a soft voice.
"But if you think I'd sit by and let another touch you, you're in for a surprise." He leans away, hands drifting down your body until they settle on the waistband of your underwear.
"Because you're mine. Just as much as I am yours."
With those final words, he tears your panties away from your skin.
You're not surprised by his actions, only complaining to him that they were your favourite pair, watching him smile up at you before leaning down to kiss your stomach.
His hands are firm on your skin, daring you to try and move. He grips your hips as his lips trail down your stomach and over your thighs. You let out a sharp cry when he grazes his teeth against your inner thigh, his tail moving to circle your other leg, holding you open for him.
You watch him, as his eyes land on your dripping centre. You watch the way his mouth parts, the way he runs his tongue against the edge of his teeth as he looks at you.
"Fuck." He says suddenly, and you can't help clenching at the low, guttural way the word leaves his lips.
You let out a shaky sigh.
"Please." You beg, voice trembling in desperation.
His eyes flit up to yours, eyes a dark red, barely noticeable, but yet still so distinct.
He doesn't speak, dropping his head to kiss your slit.
You let out a soft hum, enjoying the way his lips feel, and then making another sound of approval as you feel his tongue for the first time.
His first proper lick makes you gasp loudly. His tongue is just rough enough that you feel where every part of it rubs against you.
He's gentle as he licks you, and when he touches your clit, you cry out.
It almost feels like too much, and in the pleasure of it, you try to squeeze your legs closed, but you're unable to do so with his tail and his hand keeping your legs wide.
He presses his tongue flat on you, shifting his head slightly so that it feels good, but not nearly enough.
He groans, pulling back for a moment to speak.
"You taste so good, mistress, I could do this for hours."
His lips close around your clit for a brief moment, before he focuses the tip of his tongue right on that spot. You jerk in bliss, your thighs tremble.
"Billy. Billy. Please. Please." You beg.
With his tongue on your clit, you hear him let out a short laugh.
"Yes? Is there something you need?"
Fuck. How could he play with you at a time like this?
"You. Need you." You gasp.
"Me?"
Without thinking, you reach down and gently take one of his horns in your grip.
When he stops moving, you look down at him in concern that you make have crossed a line.
Instead, he looks at you with so much heat in his eyes that it floors you.
With half-lidded red eyes, he reaches for your other hand, wrapping it around his other horn.
"You better hold on, baby." He says, leaning down to continue licking you.
His slick tongue probes you, exploring your cunt in ways you've never felt before.
Your grip on his horns tighten when he starts licking into your entrance and over your clit at a steady pace. You let out a prolonged cry of his name, feeling your body tremble as the pleasure overtakes you.
He moans, the vibrations send tingles over your body, the wet sounds of his tongue on your cunt adding to the pleasure.
You hold his horns securely, back arching involuntarily as you feel your orgasm fast approaching.
Tears spill from the corner of your eyes. You pull on his horns to keep him close though you try to fight the sensations by attempting to close your legs. He doesn't let you, keeping you wide open for him instead.
His tongue speeds up, swiping over your clit repeatedly, he circles his tongue on you. You can't help the pitiful sob that leaves your mouth.
You cry his name, he doesn't stop.
You tremble violently when you cum. Your body spasms and shakes but you can't control any of it because you're too lost in the bliss to focus on anything else. Like molten lava spreading through your veins, sending scorching hot pleasure through your body, your clit throbbing as Billy continues to lick you softly through your orgasm.
You pant, struggling to catch your breath with the onslaught of bliss, absentmindedly realising that you've been gripping his horns harshly- you release them suddenly so that he can move away if he wants.
He doesn't budge, continuing to lap at your dripping pussy until you whine from the overstimulation.
His lips are shiny with your arousal, eyes like rubies as you watch his tongue swipe over his mouth.
You swallow, body tingling at the sight of him, aching for more.
"Can I-" Your voice cuts off, shocked at the absurdity of the question you were about to ask. More? You wanted more? How could you possibly ask him for more after he'd given you so much already?
"Mistress?" Billy asks curiously with a tilt of his head, his eyes reverting back to his natural dark hue.
"Nothing. It's nothing. Thank you Billy." You say, sitting up.
He reaches out to stop your movement, hands on your shoulders, thumbs circling your skin.
"Whatever it is, you can ask. I'm here to serve."
"That sounds awful." You say with an apologetic twist of your mouth.
He grins, leans down to place a soft kiss on your lips.
"Let me put it this way, if I didn't want to... I wouldn't."
You swallow, nodding.
"I want... more." You whisper, unable to meet his eyes.
"More?" He echoes.
You nod shyly.
He cups your face between his hands, angling you up to meet his eyes that have gone right back to their crimson colour.
"More of my tongue? Or something else?"
"T- tongue." You whisper so softly in hopes that he doesn't hear.
"Would you like to try sitting on my face?"
Your eyes widen.
"What?" You ask, perplexed, your body warming with the thought of sitting on his face, gripping his horns for leverage while he-
"I'll take that as a yes." He says suddenly, flipping you both until you're seated on his adonis belt. You gasp in surprise at the sudden movement, and then groan as your bare center rubs against him.
His hands smooth over your thighs, to grip your hips.
"Are you sure?" You ask him cautiously.
"I'm sure if you are." He agrees, and you don't hesitate any longer, shuffling your way up his body. When you lose your balance, he grips your hips tighter to hold you securely.
Billy is aching below you. He wants another taste badly, he's almost impatient to feel the weight of you on his face, the way you'll moan and buck your hips for him while he gets another taste of you.
He waits, he's calm through your hesitation, reassuring when you freeze.
"It's okay, I want this." He murmurs below you.
You take a slow breath in as you make contact with his face.
Billy groans below you.
"Oh shit-" You say, moving to raise off of him, "Did I hurt you-?"
He groans again, hands tightening on your hips to pull your weight back onto his face. You gasp when his lips seal around your clit, distracting you from your worries of crushing him.
"Oh fuck Billy." You cry.
His tongue is deliciously amazing, coarse and gentle, working into an eager pace. You can't help reaching down to grip his horns, a move that gets a moan of approval from the demon below you.
His tongue traces circles, careless patterns of pleasure that guides you into rocking against his face involuntarily, panting his name on each breath.
"So good Billy, please, I need you so bad." You praise, rolling your hips onto his rough tongue and feeling the dizzying pleasure take control of you. He's everything you've ever wanted, your deepest desire come to life and when he kisses your clit, you can't help jerking in surprise at being brought up to the edge so suddenly.
He doesn't stop, swirling his tongue, plunging it as deep into you as he can possibly get, hands gripping you tight so that you can't even think of pulling away.
When gripping his horns is not enough, you allow one hand to delve into his hair, tangling the strands between your fingers before tugging.
His hands squeeze down impossibility tighter and in the moment, you realise both your bodies are communicating the same thing; don't you dare pull away from me.
The thought alone is euphoric, that he's happy to be exactly where he is, and with a few more ruts of your clit against his tongue, your body tenses, muscles spasming as you cum hard for a second time.
You barely have any faculties left to help you stay upright. Your body relaxes without your permission, and you allow yourself a space for your body to hit the bed.
You try to extricate yourself  from him, but he only growls, grabbing your legs to spread them apart so that he can continue licking your pussy.
You let out a harsh cry, his tongue avoids your clit as best as possible, and you realise as an afterthought, that this is him cleaning you up just the way he did a few nights ago.
When he's done, he raises his head to find you looking at him with glassy eyes.
"Need you." You gasp out, and you keep your eyes on him as he crawls into the space beside you.
You bury your face into his warm skin, your body still sending wave after wave of pleasure down your spine.
His hand is soothing on your cheek, thumbing at the glistening tears there.
If you had any reservations about asking for what you wanted, it's completely gone from you now.
"Want your tail. You- you said you could- you said I just had to ask-"
"Shhhhh, easy, take a deep breath."
"No," you fight, "I need you now. I feel so empty Billy. I've never felt this empty before."
He lets out a slow breath.
"Okay, okay, I'll give you what you need."
You hum in appreciation, hooking one leg over his hip, spreading the other eagerly. Open thighs for your demon to fit his tail into you.
"I should open you up a little on my fingers." Billy suggests, and your impatience gets the better of you, but when you open your mouth to protest, you catch sight of his tail and pause. The widest part of his tail is about the width of three of your fingers, and you know it would hurt a little to take that much into you.
"Okay." You whisper, meeting his eyes, a little daunted by the acts you were about to undergo, yet too desperate to stop now.
His large hand covers your pussy, his middle finger makes contact with your entrance. Your breath freezes in your throat at the delicious sensation of him rubbing your entrance.
"If anything hurts, you stop me. Okay?"
You blink, eagerly nodding your head.
He gets his finger nice and wet with the abundance of your arousal before he sinks his first knuckle into you. You gasp in a deep breath, tilting your hips up in a silent beg for more.
Billy is meticulous, careful, as he works his middle finger right into you, you barely feel any pain at all.
When he reaches all the way in, and you can feel him so impossibly deep inside of you, he pauses.
"How does that feel?" He asks, eyes trained on you. You turn to look at him, desperate eyes on his warm ones.
"Feels s'good."
"Yeah? What about when I move like this?" He asks, bringing his lone finger out and then pushing it slowly back into you.
You cry out, head falling back, eyes squeezed shut. He doesn't stop his slow movements, and you find yourself rocking your hips in time to his movements.
"It's not enough." You whine, "I need more."
"Okay, this may pinch a little bit, take a deep breath for me."
You do as he says, and in the exhale, two of his fingers probe your entrance.
He's right, two of his fingers pushing into you does pinch, and when you gasp in pain, his hand freezes.
"I'll stop." He says, beginning to withdraw his fingers from you.
"No please," you beg, "I need it, please Billy, I want to."
You hear his gulp, and feel as his two fingers attempt to push into you once more.
This time, he takes it even slower, allowing his fingers time to get wet with your arousal, before fucking them into you. You whimper, desperate and eager for the feel of his fingers. It makes you feel so full, in a way you've never felt before.
"I'm gonna open you up on my fingers." He whispers hotly in your ear, his voice sending shivers of bliss down your naked body.
"I'm going to stretch my mistress' tight cunt, until I can fit my tail in. Can you guess what I'll do next?"
You gasp, turning to look into his vermillion eyes, unable to say a word as his fingers do just as he says.
"That's right. I'm going to fuck you with my tail. Make you cum on it, maybe I'll make you clean your own cum off of my tail, kiss you so that I get the taste."
You squeeze your eyes shut.
"Maybe I'll flip you on your stomach and fuck my tail into you from behind. Maybe I can keep you stuffed full with it. Give you an idea of what my cock could be like."
Your breath hitches, you writhe beside him.
"I think you're ready for it." He whispers in your ear, and you think you are too.
He withdraws his fingers, and then something too familiar is working its way in.
Incoherent, your mouth opens wide to take in more air. His tail feels different than his fingers, thinner at the top, and only a little wider at the base. You clench around him eagerly, hearing him groan as he pumps his tail into you.
"I can't tell you how much I think about this. How often I've touched myself to the thought of being inside you." Tears spill onto your cheeks, you realise that you can feel the rough bumps on his tail rubbing against your inner walls, amping up your pleasure.
He starts slowly, but when he feels how eager you are, his pace increases.
You sob more, unable to form a single thought in your head past the pleasure if you tried.
You reach for him, grabbing onto the first thing you can reach- his wrist- and squeezing tight.
Billy leans closer, so that his lips brush your ear.
"I know, I know it feels so good. I can feel your pleasure- did you know? I can feel how mindless you are. It's a good thing you don't need to think. All you need to do is cum."
Your nails claw into his skin, he chuckles, his thrusts growing harsher.
He readjust his angle slightly, and a sound of pure bliss leaves your mouth.
"You feel so good, and you taste even better and you're all mine, mistress."
Your breath stutters in your throat, his tail slows it's pace, prolonging your pleasure, sliping in and out of you so calmly now, still touching every desperate part of you.
He reaches up, his fingers sinking into the pliant skin of your jaw, and tilting your head so that you can look into his eyes.
More tears leak down your face, as his tail continues to take its time fucking into you so sweetly. The pleasure burns inside you, scorching hot and sears ecstasy into your mind until you can think of nothing else but him.
He looks down at you, drinking in your expressions, feeling your pleasure in the back of his head like a light going off- some big realisation happening inside of him as he gives you what you crave.
"In truth," Billy utters, "I want to own you."
He feels you clench around his tail.
Your breath stutters.
"I've found myself tied to you for a very long time. I'm at your mercy. At your service. Anything you want, I provide- and the concept of it makes me so fucking angry."
You blink, trying to focus.
"Bill-" You start to say but his palm swiftly covers your mouth, and you huff through your nose, raising a hand to cup his, not attempting to pull him away just yet.
"Not angry at you, angry at the entire system that put me here in the first place." He looks away, and after a few moments he confesses, "You're the one thing that's good about this."
He looks at you again, and then leans in, moving his hand out of the way so that he can press his lips to yours. His tail stills inside of you, pressing in deeply, you try to focus- to return his kiss- but when his tail shifts upward, you let out a sharp cry against his lips as he touches an incredibly sensitive spot inside of you.
Your body shakes, your eyes widen in shock.
"There it is." He says, as if he was looking for this spot inside of you all along.
Too desperate for the pleasure, you open your mouth to speak.
"If it's ownership you want, then it's yours." You say, watching his eyes flash bright red for a second.
"Own me."
A low sound leaves his chest, and then his mouth is on yours again, and his tail begins to fuck you earnestly.
You cry out against his lips, and he takes the opportunity to delve his rough tongue into your mouth. Your breath catches, feeling absolutely consumed by him, fucked by his tail, invaded with his tongue until there's nothing left that you wouldn't give.
"Prove to me that I own you," he murmurs against your lips, "and cum for me."
You nod eagerly, as his tail moves faster. He dips his head to lick against your neck, one hand trailing down to press one of your peaked nipples between his thumb and forefinger.
You shudder. Your body no longer feels like yours- only a toy for him to manipulate whichever way he likes.
A loud sound breaks past your throat, you tilt your neck to give him more place to work. His lips continue to suck and torment at your shoulder, until you feel the pleasure of his touch grow to be too much for your body to contain.
You entire body pulls taut, one hand grips the sheets, the other holds his wrist, your breath lingers in your chest as you stop breathing.
Your back arches off the bed when you come.
It's like some large explosion going off in your head, your vision goes white, pleasure sparks down your spine, and your very thinking unspools as your orgasm moves through you.
You're gone for a moment, floating somewhere very far away, unable to get back to your body no matter how hard you try.
"Shhh, relax, mistress, I've got you." You hear him say, and you allow yourself to float peacefully, with the knowledge that you're cared for above all else.
When you come to, you're pressed tightly against him. You take a deep breath, your vision swims for a moment before it focuses. His tail, now clean, is wrapped around your thigh, you cunt tingles and aches, throbs in bliss at being used so well.
"How long was I out?" You ask him.
"Couple of minutes, that's normal." He says in an attempt to reassure you.
"How did you- I've never... come that hard before."
Billy hums in acknowledgement.
"You should expect a lot more of that." He says, and you feel your body pulse with excitement.
Your limbs feel heavy, your breathing slows, calmed by his closeness.
"I didn't make you cum." You say after a few moments, feeling his hot erection through his clothes, pressing against your thighs.
"That's alright, it'll go away."
You frown.
"That's not what I want." You challenge.
"No?" He asks.
You fight the exhaustion, sitting up, and turning to look at him.
"No." You say, leaning down to kiss him.
He hums against your mouth, and then stiffens in surprise when your hand drifts downward to cup his straining erection.
"Want you in my mouth." You say decisively, reaching for the button of his pants to undo it.
You get his pants off with only a little difficulty, and then tug his boxers off too. He doesn't do much more than shift his hips when necessary, to get them off.
And then it's just you and his cock.
Big... too big.
He'd never fit all the way in your mouth, you may have to use your hands like you've seen in porn, but you're determined, eager to feel him come undone below you.
You pause, looking up at him. He looks flushed, propped up on his elbows to get a better look at you, eyes and cheeks tinted red until you're sure he's the most beautiful thing you've ever seen. Even his chest is coloured with an undertone of pink, flushed and eager for you.
Precum dribbles from the head of his cock, large and mouthwatering and before you lose your nerve, you lean forward.
He hisses when your tongue makes contact with the tip of his cock. Salty precum coats your tongue, your eyes meet his as you savour his taste.
His lips are parted, the sheets clenched in his fists on either side of his body. You smile at his reaction, leaning down to kiss his cock.
He groans, low and primal and you get the idea that he's barely contained, ready to rip at the seams at any given moment.
You think about all the amazing things he's done for you, and you don't hesitate to suck the smooth tip of his cock into your mouth.
He fills your mouth easily, you press lower until you're at your comfort limit. You can hear his shallow breathing above you.
With a new thought in mind, you raise your head.
He looks at you, and you look at him, and before he can utter a word of question, you reach for his hand, gently running your fingertips over his clenched fists before pulling at his wrist.
He releases the sheets and allows you to pull his hand up until his hand is cupping the back of your head.
"Can you help me?" You ask softly, and his eyelids fluttering while he blinks is the only indication that he's heard you.
You give him a gentle smile, sinking lower once more.
It's slow and deliciously sinful, he keeps a steady hand on the back of your head while you suck his cock, enjoying the delightful sounds he makes.
When you feel confident enough, you wrap your free hand around his cock and begin stroking him to the slow pace of your mouth.
"Fuck, you're so good at this- I don't deserve it." You hear him say, which makes you raise your head to speak.
"Of course you deserve it, Billy, you're such a good demon for me."
He closes his eyes with a groan, and you let out a breathy laugh, dropping your head once more.
You keep going slowly enough, until your jaw starts to ache, something you hadn't realised would happen.
You do your very best to ignore the ache, trying to focus only on the taste of his veined cock and smooth tip.
You begin to move faster, keeping the pace of your hand in time so that you can pleasure as much of his shaft as possible.
"You're amazing mistress, fuck."
Billy's head tips back, gasping for air as pleasure assails his senses. Your mouth on his cock had been everything he'd ever dreamed of and hoped for. The inside of your mouth was soft and hot and your tongue- holy fuck your tongue was going to kill him.
Worst of all was when you took him a little too deep and you gagged a little around the head of his cock. He could feel your throat contract around him, it had made him feral to own you. He'd resisted thoughts of gripping your head and fucking your mouth, saving the filthy thought for later, knowing that he'd get everything he wanted in time.
Billy's eyes roll back in his head, he's so close, all because of you, and your sweet smiles and your perfect mouth and he couldn't get enough of you if he tried.
"Close." Is all he can find the strength to say, and then he feels your efforts double down.
He groans when he feels you speed up, and you're desperate and eager to feel him explode in your mouth that you hyperfocus only on his cock.
You feel his abdomen tighten, and the muscles on his thighs contract, his hand holds fast to the back of your head.
There's a low groan, and you take his cock all the way into your mouth as he comes.
You squeeze your eyes shut, trying to make yourself as comfortable as possible as waves of his cum flood your mouth.
You swallow as much of it as you can, but inevitably, some slips out of your mouth.
You pull up with a gasp when his cock stops pulsing, looking up at him and finding his head tilted back, his chest heaving.
You can feel something warm settle in your head, a fog that relaxes you, soothes your soul, and you can't help the need to clean all of his cum.
You take your time, licking his shaft, seeing him raise his head to look at you in surprise as you begin cleaning him up. His cock hasn't softened at all, and you moan in delight, swirling your tongue over his tip to catch the last bits of his cum.
"I think I love the way you taste." You murmur, looking up at him with hooded eyes. He takes your chin into his palm, tilting your head up to look into his eyes.
"Are you okay?" He asks softly, his eyebrows drawing together in concern.
"Yes. Your cock is massive and delicious." You try to explain.
He sighs, tilting your head from side to side, examining something you can't see.
"Your pupils are blown wide." He comments, concern lacing his voice.
"Can I kiss you? Are you one of those guys that doesn't like to be kissed after a girl sucks you off?" You ask as if he hasn't spoken.
The corner of his mouth twitches, amused.
"You can kiss me anytime you please, mistress."
"Yay!" You cheer, leaning up to press your lips to his.
You moan into his mouth, kissing him softly, savouring the way your naked body feels sliding against his.
"I'm not afraid of you." You whisper aloud in realisation, that this is probably the most intimate you've ever been with another person and having him here didn't scare you. You knew he wouldn't try anything, or force you in any way, that you could just be you, without needing to guard yourself from him.
His hands trace your spine, squeezing gently at your body when the exhaustion finally hits.
You huff out a sigh, tucking your head into the crook of his neck, rubbing your cheek against his stubble every now and then.
You head is still hazey, and you're not too sure why, but you don't focus on it at all.
"Your cum tastes amazing," you mumble sleepily to Billy, who has tilted back on the bed to allow you to rest on his chest while you drift off.
"So you've said." He hums.
"I need to taste you again when I wake up." You sigh against his chest, feeling his hand pause for a moment while rubbing your back, only resuming his soft motions when you make a sound of complaint.
You lick your lips, feeling his tail wiggle it's way to wrap around your thigh, smiling softly as sleep overtakes you.
Billy had never had a mistress before, definitely not one he was attracted to. Yet he had the sneaking suspicion that his cum had drugged you in some way. No one had mentioned that being possible, and he racked his brain to remember the last time he'd been sucked off.
Nothing came to mind.
Had the last time he'd been treated this way really been when he was alive?
He swallows, figuring that eternal damnation definitely didn't intend to come with blowjobs this good.
You shift in your sleep, muttering about peaches, your breasts are fitted snugly against him, and he sighs in bliss. He can feel the soreness in your jaw through his bond, and he rubs your jaw softly, his fingertips glowing purple as he soothes your ache. The ache you had from sucking his cock.
He pauses, thinking for a second that he should have left your jaw sore- a reminder to you that you had him in your mouth, but then guilt fills him- he didn't want you in any pain.
Billy blinks, wondering about his feelings, and not surprised at the conclusions he comes to about himself.

Tumblr media
Two men sit, facing each other angrily. One has devoted himself to his religion, prides himself on the strength of his morality, the other, has killed more people than this church can hold.
"I could kill you right now without batting an eye." Billy says easily from his spot beside you.
"He's not going to kill you, I promise." You speak up, trying to deescalate the tension in the room.
Matt turns his head to face you, giving you a sweet smile which you can't help but return even if he can't see it.
"We just want some answers." You say, trying to keep your tone nice and soft and airy enough to keep the peace.
"Ask away." Matt permits.
"How'd you lose your eyesight?" Billy asks invasively.
"Billy!"
Matt grins.
"It's fine. I was in an accident when I was a kid, some really toxic chemicals got into my eyes. I'm not totally blind though, I do have partial eyesight... but it's just mostly shapes."
"Oh, I'm sorry." You say, sympathising with such a traumatic event.
"It's really okay, losing my sight sharpened my other senses and helped me develop a sixth." Matt turns his head to Billy, the smile dropping from his face, "I bet that answers your next question."
Billy rolls his eyes.
You try not to laugh at both men clearly despising each other.
Matt had initially been skeptical about speaking with Billy in the first place. But after pleading with him, he'd allowed you both the opportunity to ask questions in his office, pertaining to his ability to recognise you.
You saw Matt as an asset, possibly even a friend, Billy saw him as a stain, to be wiped out.
"Mistress," Billy says to you, "It would take me a minute to make his death look like an accident."
"No, Billy." You emphasise.
Matt gives Billy a smug smile.
"Down boy." He taunts.
Billy's out of his chair almost immediately, striding angrily to Matt, sitting on the other side of his desk.
You move too, sliding between the desk and your angry demon, a calming hand on his chest.
"Hey," you whisper to him, and his red eyes meet yours, "Please? We just need some answers and we'll be done soon."
Billy takes a deep breath, eyes reverting to brown, he nods before taking a step back.
You turn to Matt a little angry at his disrespect.
"He doesn't have to be bound to me. He could kill me just to get to you."
At the same time, both men speak.
"He wouldn't do that."
"I would never do that."
You swallow, glancing back at Billy, a little perplexed by his overall reaction to Matt. Why did this one priest make him so angry?
You turn to Matt next.
"How do you know that?" You ask softly.
Matt takes a moment, before extending his hand to you, palm up for you to take.
You hear Billy let out some type of low growl as you place your gand in Matt's, but you're unable to pay him any mind, too focused on what Matt could possibly be sensing. Something deep inside you calls out to let him go, to step back and spit in his face and you frown at the irrational thoughts.
"Whatever chance Billy had to get rid of you is long gone. There's so much of his energy wrapped around you that killing you would kill a part of him."
Your lips part in shock.
"What? How?" You ask.
"The longer you stayed bonded, the stronger the bond grew. It would have cost him nothing to kill you when you first met? Now? It'll take a part of him too." Matt explains.
You turn to look at Billy, his eyes are on the floor, doesn't meet yours at all.
He knew, and he still kept you alive.
"What if I die?" You whisper, and you feel a sharp pain move through the space between your lungs at the thought.
"Depending on how strong the bond gets, it could kill him too."
The thought squeezes your throat till you can't breathe, and still Billy won't meet your eyes.
"It's unbreakable right?"
"Yes... but... distance and time apart can weaken it some."
To Billy, you whisper softly.
"When I'm close to death we can try that? So part of you won't have to die with me."
Those words finally make him look up angrily, with irises turning red.
"You expect me to leave you before you die? I don't care if part of me dies with you, I'm not leaving your side."
You open your mouth to protest and he shakes his head.
"Even if I could, it would put us both in an unquantifiable amount of pain to be apart."
You close your mouth, turning back to Matt.
"Is that it?" You ask softly.
"I can also sense that he wants to corrupt you."
You swallow at the thought.
"What demon doesn't?" You ask rhetorically, and instead of waiting for Matt to release your hand, you pull it away.
You sigh, rubbing where Matt was touching to wash away the sensation of his hold, you avoid Billy's gaze.
"Thanks, Matt." You say, appreciating the difficulty of the situation you'd put him in.
"Anytime... and you can always come to me if you need help." You turn to look at him, "You... not him." He emphasises.
"I understand," you say with a smile, bidding him goodbye as you exit his office with your demon trailing behind.
There's something of a tense silence between you, something you hate because it makes everything feel awkward between you and you didn't like it one bit.
"Mistress." Billy finally calls.
You pause, looking back at him in the church aisle.
"I'm sorry." he finally says.
"For?"
"This entire thing. I'm sorry it happened."
You swallow, nodding.
"I'm sorry too." You supply.
The corner of his mouth twitches, his hands are deep in his pockets and his shoulders are hunched and you think this is the first time he's let himself be this vulnerable.
"What could you possibly be sorry for?" He asks in amusement.
"Everything," You answer, "We've just been dealt really shitty hands by the universe and I'm sorry for that."
He smiles sadly, stepping forward, he wraps his arms around you. You eagerly return the hug.
"It's less shitty with you." He finally whispers into your hair. Your arms squeeze him tighter in agreement.
~~~
"Maybe I was jealous." Billy murmurs, opening one of the kitchen cupboards to peer inside.
You pause your examination of the countertops.
You'd been searching for a new apartment ever since you found out that the people that had tried to kill you knew where you lived. In true Billy style, he'd narrowed the search down to some very upscale apartments that he felt were the safest, and now you just had to pick one from his carefully curated list.
"Jealous? Billy... there's no need to be jealous of Matt. It's not like- I mean- I doubt I'm even his type." You say, crossing your arms to look at him. The conversation you were having right now had come up after he'd made a displeased comment that this apartment was only a couple of blocks away from Matt's church... to Billy's dismay.
He closes the cupboard door to look at you.
"Explain."
You make an exasperated sound at the back of your throat.
"Circumstances aside, he'd never go for me anyway, I doubt I'm the type he goes for." After a few seconds of contemplation, you speak again, "Hell, I doubt I'm the type you'd go for."
"And what does that mean?"
You throw your arms up in exasperation.
"Do I have to spell it out for you? I'm weird and awkward and... and ugly!" You heave in air, turning away from him.
"Wanna know why I'm a girl well into my twenties and still a virgin? Well it's cause no one I like wants to fuck me. Obviously."
Before he can say anything, the realtor, who'd been in the other room taking a call, steps in.
"How is everything going? Are we feeling good about this one?" She asks with a voice that's way too excited for the embarrassed way you feel.
"Alice." Billy says her name, in a calm way and you keep your eyes fixed on the floor length windows.
"Um, yes?" She responds.
" I'll give you double if you give me the keys right now and go home."
You swallow, finally turning to look at him in surprise.
Alice, who's brain has just caught up to the profit she stands to gain from accepting, speaks up.
"Consider it done, I'll be back tomorrow with contracts and payment plans drawn up." She pulls the key from her pocket and hands it over to him.
"Sounds great. Have a nice day." Billy says, accepting the keys.
Alice pauses for a second, before nodding her head and grabbing her purse to walk out the door.
You have so many questions coming to mind as you hear the door shut. There was no way that renting or buying such a high end apartment had been so easy. No way.
But while you had been waiting to speak, Billy had had a lot more in mind. He's striding up to you angrily as the front door shuts.
His body against yours, you gasp as he grips your shoulder tightly to keep you from backing away from him, not that you could as he traps your body between his and the kitchen counter.
"Let's get one thing clear," he murmurs angrily, his eyes going red swiftly, his tail wrapping around your hips to press your body tightly to his.
"I have yearned to fuck you from the minute I laid my eyes on you." He says hotly, and you can't help swallowing as pure, unadulterated heat flushes through your body.
"Every night, I think about being inside you, when you're fast asleep beside me, curled into me, dreaming your pretty little dreams," His lips graze the shell of your ear, "I think about how badly I want you, how much I need every clench of your cunt, every drop of your wetness, to be because of me."
You're not sure you're breathing anymore.
"And I know how irrational that is. Not even you have control over who you get wet for, and yet I ache for it anyway."
You breathe a sigh of his name, aroused right now because of his words.
"Be realistic," you try to protest, "You would have never even looked my way if we weren't bonded." The truth of the words almost choke you, you can hardly meet his eyes.
Billy lets out a rough sound of frustration. He presses further against you, burying his face snugly against your neck, holding you as tight as possible to his body as he can. He dwarfs you in size, his large frame enveloping yours easily.
"You're wrong," You gasp in surprise as his fingers find the button of your jeans, undoing them easily and pushing them down your thighs, "You're so wrong."
He strips your bottom half, and you don't even think to deny him, your body's memory of the pleasure he can give is too potent for resistance.
You shiver with delight when he lifts you, sitting you on the edge of the countertop and spreading your legs.
Once again, he looks between your open thighs for a long time before he licks his lips, a hot, languid feeling spreading through you like molten lava.
"I can't remember the last time I wanted something as bad as I want you." Billy whispers finally, before he drops his head to seal his lips around your clit.
You moan in surprise and delight.
You can barely hold your body up as you feel his tongue begin to work over you.
A blissful moan leaves your mouth at the eager way he licks over you. Your nails scratch at the countertops, willing some level of destruction onto the cold marble, trying to unravel something the way he unravels you.
You swear, and you plead, and you don't even understand what you're asking for because he's already giving it to you.
The worst thing is that he moans, enjoying the way you taste, and the way he makes you feel. Briefly, your brain reminds you that he can feel this, he can feel the pleasure swimming in your veins, and he knows exactly what he's doing to you and it makes you almost feral to be as close to him as physically possible.
It's almost too much for your body to handle. The way you feel for him, and the pleasure he wrings from you and the sensastion of his rough, slippery tongue exploring every inch of your most sensitive parts like he owns you wholly and your pleasure is his and only his to do with it whatever he pleases and the pressure builds in your head and it builds and builds and spills from your mouth and curls your toes and still it's all Billy and the power he wields over you.
Your entire body shakes when your orgasm hits. With the force of a tsunami, the brilliance of lightning coursing through your veins, aftershocks that don't slow down until he manages to pull his tongue away from your dripping center.
You gasp, heaving in air, unable to focus, or think with that much bliss drunkening your every nerve.
He leans up, an insistent hand cupping the back of your neck so that he can push the taste of your release into your own mouth. Like a doll, you accept it, limbs too pliant to stop him, mind too hazy to even consider denial.
You hum against his lips, eager for anything he has to give you.
"So," he whispers softly, his tail trailing over your thigh, "I don't wanna hear you say a bad thing about yourself ever again. Understood?"
You pout.
He laughs, pressing his forehead against yours.
"Dont give me that. Be a good mistress and do as I say."
"But I'm the one in charge," you whisper hoarsely, "you need to do what I say."
Something dangerous sparks in his eyes.
"Really?" He challenges, and the next thing you know he's lifting you off the counter, grinning at your sound of surprise.
You curl against him, content with wherever he's taking you.
"You're my demon," you murmur cheekily, "not the other way around."
"Am I?" he inquires, dropping you onto the soft black leather couches of the living room.
"Mhmmm." You hum an affirmative, letting him turn your body however he likes, until you're almost bent over the back of the couch, facing the magnificent floor length windows that overlook the city.
You gasp in surprise when he tears your shirt in two, tugging your bra off as well, until you're naked and dishevelled before him.
You don't get a chance to turn and look at him, before you feel his front cover your back, skin on skin, telling you that he's shed his clothes as well.
His tail wraps around your midsection, you hum in appreciation at his gentle caresses.
You gasp when you feel him spread your thighs, and you tense when he manages to slip his cock between them.
He lets out a blissful sigh of relief, one that goes right to your head and sinks down to your core. You can feel his cock, using your arousal as a lubricant to slide between your thighs. The head of his cock even reaches so far that it bumps your clit, and you find yourself fisting the soft leather of the couch.
His hands on your hips, his stature behind you is large and imposing, trapping you against the couch so that he can fuck your thighs however he pleases.
"I think about fucking you like this all the time." He whispers in your ear, and your eyes flutter shut, clenching as his cock slides along the outside of your cunt.
"I could do anything I want to you right now," To prove his point, he pulls his tail away from your midsection, and wraps it around your neck. You open your eyes in surprise, titling your head up to look at him when he pulls your back flush against his chest.
You let out a small cry when his fingertips meet your stiff nipples, aching for his attention. 
"So while you may be my mistress," he bends his head till his lips meet your ear, "Don't forget who's in charge."
When you orgasm this time, it's completely unintentional. His words are directly responsible, and you whimper and cry as wave after wave of bliss overtakes you, more of your arousal soaking his cock.
When you can breathe without being overwhelmed with pleasure, emarrassment overtakes you.
"S-sorry." you murmur.
Billy grabs your jaw, keeping you face turned towards him so that he can lay a harsh kiss on your lips.
"For. Fucking. What? Being so sensitive for me that your pretty body can't handle it? Making me fucking ache to be inside you so bad?"
Your stomach tingles at his words, he presses his forehead to yours. Your eyes are closed, you reach for him in your head, surprised to feel your warm affection returned.
"I can't believe I have this much self control. I want you so bad I can't stop thinking about it. But I know you're not ready, and I'm not trying to force you. I'm happy with whatever you want to give me, and I'd love to be your first if you'd have me. I've thought about that too."
You're not even sure that he's still talking to you, and not just rambling thoughts that spring to mind.
"You have?" you ask, hoping not to break him from whatever trance he was in.
"Of course I have, of course. It wouldn't be like this," He murmurs, most likely indicating to the position he currently had you in, pressed between the couch and his body, your back to his warm front.
"What would it be like?" You ask, "Show me."
He pulls his forehead away from yours, blinking down at you.
"What?"
"Show me... how you'd take me the first time."
He shudders out a breath.
"Sure?" he asks.
"Yes." You confirm.
"Well it wouldn't be here." He says with determination in his voice, leaning away to turn you around, wrapping your legs around his hips, his hands sliding under your behind before he picks you up. You wrap your arms around his neck to hold on, pressing your head to his collarbone with a little giggle of surprise.
"I'd do it on a bed, so that you're relaxed and comfortable and open for me."
He walks you into the bedroom, that you didn't have a chance to look at before he'd decided to take the apartment.
It's beautiful, with black walls and dark bedsheets and blackout curtains that satisfy a hidden craving within you. The only lighting is below the bed, and behind the mirrors in the room, making everything awash with a soft glow instead of a harsh, direct light.
Even the headboard is backlit, and it soothes you, reminds you of the devilish man holding you, placing you gently onto the dark sheets and making you feel like a person about to be thoroughly worshipped.
His eyes glow in the darkened room, taking slow, deep breaths in what you think is his attempt to calm himself.
"What next?" you whisper softly, wondering how far you're willing to let this go.
"Next, I'd get you comfortable, make you come on my tongue a couple of times." He murmurs, crawling towards your parted legs.
You stop him with a foot on his shoulder, making him pause his preadory pursuit to look up at you.
"What if I'm already comfortable?" you ask, hoping he understands.
Predictably, he does understand, and he smiles, moving your foot away so that he can crawl up your body instead.
He hovers over you, red irises meeting yours, you can't help shiver at the sight of his large frame and defined muscle.
"Then, if you're nice and comfortable, I'd start you on my fingers. Would you like that?"
"Yes please." you murmur on a breath.
A small smile on his face as you feel his hand trail over your skin. Over your hip, he swirls a couple of circular patterns before cupping your mound.
You can't help gasping, sensitive to the sensations he gives you.
You part your thighs, to give him more space, and he smiles in approval of your actions.
"I'd start slow, with just one finger." As he speaks, he carries out the action, pressing a single finger to your dripping entrance.
Pleasure sparks within you as your body accepts his lone finger easily, pumping until your leg begins to twitch, before he's withdrawing from you to add a second finger.
You hiss in surprise, the smallest hints of discomfort at first before the absolute pleasure of fullness.
You sigh blissfully, body sinking deeper and deeper into the soft sheets, gasping in surprise as he draws his tail up to wriggle gently against your clit. You clench around his fingers helplessly.
"I'd tell you how good you're being for me, mistress, so eager and ready to give me your wet little cunt. How happy that makes me. How badly I want to please you."
You groan.
"Want a third?" He asks easily, and nothing could ever hope to stop you from nodding yes.
"Breathe for me." He guides, and you try to do as he says while he works a third finger into you.
He does it well, moving in and out slowly, letting your arousal coat his fingers before he continues, pumping in slow little motions that cause pleasure to overshadow the uncomfortable stretch.
He leans down, his tongue extending to lick over your breast.
You gasp, clenching around him, his tail on your clit and his fingers inside you and suddenly you begin to burn with the too little stimulation.
"Need to cum, Billy, please, 's too much I-" You gasp, unable to finish the sentence.
He understands, he always does.
Everything increases.
The speed of his fingers and the movements of his tail and even his tongue hastens its licking on your breast until you're shaking once more and you can't stop youself and you don't want to.
One of your hands reaches into his hair to grip it harshly, a low cry as he plays you like an instrument, fiddling with your body until you have no choice but to orgasm, back bowed, body shaking, vision going black in the bliss.
It's so amazingly good, it's all you can feel, pure euphoria, a loss of your faculties as he lays claim to your body and your pleasure.
When you come to, it feels like you've sunk even deeper into the sheets, gasping as his face comes in to focus.
He cups your face, and he waits patiently for the tremors to subside, his fingers petting along your cheek in a subtle attempt to bring your reality back into focus.
You can hardly believe that this is your existence. Here, below a breathtaking demon who caters to your every need, who makes you feel safe and protected and appreciated like no one else before.
It almost feels like a perfctly magnificent dream- until you remember the circumstances of your meeting, something that reminds you that this is indeed real, and this demon hovering over you, that holds you while you sleep and eases your aches, wants to be here.
In a small voice, you speak.
"What happens next?"
A sharp grin and a kiss to your nose and he's sliding his cock between your thighs once more.
"Next, I'd press my cock against your needy little cunt. I'll use my tail this time to show you."
Though it's not phrased as a question, he waits until you nod to begin working his tail against your entrance.
You sigh in bliss as his tail works its way into you, like a familiar feeling with brand new pleasure, not stretching you as wide as his three fingers were just doing moments before.
There's a little pinch of soreness from the overuse of your body, but it's easily ignored by looking into his crimson eyes.
"I'm sorry I'm so big," Billy murmurs above you, moving his hips in time with his tail, grinding his cock between your thighs to give you a realistic simulation, "no matter how much I stretch you, our first time together is still going to hurt a little."
"It's okay," you gasp, though, in reality, you weren't complety sure it was, "I'll learn to take you." There's a determination in your voice that you hope he hears.
His tail goes in a little deeper at the sound of your words, causing you to cry out sharply in pleasure.
"Do you mean that, mistress? You'd learn to take me? All of me?" His hands smooth over your thighs, touching your skin, tracing it with his fingers before leaning in to kiss you eagerly.
It was some type of torment, to have his cock so close and yearn for it to be inside of you with no hope or possibility of getting him there- at least not tonight. His warm skin pressed to yours, his tail taking its time, working in a steady, mindbreaking rhythm inside you.
When he pulls away from the kiss, you get your chance to speak.
"I mean it," you try to speak between waves of pleasure, "I want your cock, Billy, want you to teach me how to take you."
He pressed his forehead to yours and groans.
His pace increases, until his hips are slapping against yours, the vibration adding to the pleasure of his tail inside you, adjusting his angle just right until your toes are curling and his name is leaving your lips more than normal breaths.
Your walls clamp down around him, thighs shaking as liquid fire burns through your body, an orgasm that sends cascading shockwaves down your spine. Your nails sink into his back and bicep, no fear of hurting his rigid from with your little fingers. You thrash below him, tears spilling from your eyes when your body choses pleasure above breathing and leaves you floating for a moment before you're dragged back into consciousness.
He's kissing at your cheek, something so soft and gentle, body enveloping yours as though he hopes to protect your from any external forces.
His beard scratches along your face and something inside of you snaps.
"Billy." You whisper, and you find that your voice is hoarse though you barely remember screaming.
"Mistress?" he calls, and you clench around his tail, that hasn't left you yet.
"I need your cock. Now."
A moment of hestation.
"Mistress-"
"-I need you to at least try." You say, cutting him off, "Please, please, please, please, please." You emphasize, wiggling your hips.
Still Billy tries to resist.
"I don't want to hurt you."
"Just try? Please? For me?"
You hear him take a breath.
"For you," he agrees, "Promise to tell me if you want to stop?"
You nod eagerly.
"Promise."
He pulls his tail slowly out of you, and immediately adjusts his hips so that the head of his cock is pressed to your entrance.
"Fuck." He swears.
His cock slips from your entrance, and he moves a hand down to guide himself back.
Then, he's pressing in.
You take a deep breath, mewling as the head of his cock notches into you. You gasp, blinking, trying to come to terms with the incredible stretch you're experiencing.
He's inside of you, and it's the greatest sensation, until he tries to press in more, and encounters resistance.
Suddenly there's a lot more pain, and you gasp, trying to breathe. Billy's eyes locked on you, his jaw clenched tight, eyes a dark red that you've never seen before.
He pauses, waiting for your okay to continue.
You nod your head, taking a slow breath.
When he tries to push in more, the pain overwhelms the pleasure, and your body shuts down. You squeeze your eyes shut.
"Stop- I- I can't." You cry, unaccustomed to pain so sharp in that region of your body.
For a moment, he doesn't move, and you have to peek your eye open to meet his.
His eyes have gone all black, and the unfamiliarity of the situation has fear scraping at your insides. You try to back away, and he grips your hip in warning.
"Easy," he whispers so softly that it makes you relax, reminding you that this was your demon hovering over you, and not some untamed beast that he had managed to look like in the moment.
He takes his time, easing out of you so that he doesn't hurt you too much, and you sigh in relief when he's out, your core throbbing from overuse.
Billy's eyes are still black, when he reaches a hand down to begin stroking his cock.
"I need to cum, please. Can I?" He begs, fucking his fist knelt between your thighs.
Your mouth parts in shock at his desperation. His shoulders tremble, his abdomen tightens, his teeth glint in the light like they never have before. A snarling, raging beast all because he'd been inside of you for a short time.
"Mistress." He growls, bringing your focus back to his question his need to have his own orgasm.
Your head spins with thoughts.
Where was he going to cum? On your pussy and thighs? What a waste of cum that would be.
"In my mouth." You rush out, springing up and readjusting your body so that you're on your hands and knees in front of him.
Billy groans, watching you bring your mouth closer to the head of his cock, leaning in to place a gentle kiss on his tip. Tentatively, you suck the smooth head of his cock into your mouth, moaning at the delectable taste of his precum and something extra- a tart taste of you.
"Fuck!" he gasps, and you take him as deep into your mouth as you can, swallowing as he comes.
You close your eyes, listening to his harsh breaths as he releases into your mouth, he tastes the same as last time, something that is not a favourite, but has the potential to be an acquired taste.
You enjoy each drop of his release, and it doesn't take long before your head begins swimming with haziness.
You suck him as best as you can, making sure he has no more to give, before pulling off of him and looking up with grateful eyes.
"Couldn't let you waste your cum," you try to explain, "when it's one of my favourite things."
Billy lets out a harsh breath, the darkness of his eyes slowly retreating into his pupil.
You hold his gaze, blinking slowly as inebriation overcomes you.
You crawl your way up, wrapping your shaky arms around his neck, rubbing your cheek against his chest.
"Smooth." you appreciate.
He grips your chin, and you mewl in protest when he tilts your head up to examine your eyes.
"You're cum drunk again." he says.
You giggle.
"I'm Billy drunk." you correct, swaying in his arms, after a moment you frown.
"I'm sorry I- that I made you-"
"Don't apologise for that. Ever. I never want to hurt you."
You wrap your arms around him, squeezing him as tight as physically possible.
"You're unreal." you murmur, rubbing your cheek against his chest.
"What's unreal, is how badly I need to taste you again."
You can't help laughing, thinking that he was joking.
"Something funny, mistress?"
"You are, Russo. Don't men need a break after they come?" You begin to turn away from him, mind already hazily reminding you that the bathroom was a good idea.
You don't get a chance to move too far away from him, before he's grabbing your wrist, turning you back to him and pushing you flat onto the bed.
Your head hits the pillow, a sound of surprise leaving your lips, eyes widening.
"I'm no ordinary man." He whispers against your lips, before giving you a cheeky smile and moving his way down your body.
It's poitively mind-blowing. You lose all sense of time and location, drifting throught the darkness behind your eyes while he uses his tongue on you, delving where he pleases, almost uncaring in the way he easily manipulates you into each orgasm. When you try to push him away, your skin hot and flushed with the overabundance of pleasure, he uses his influence to bind your hands above your head.
You become something unfamiliar. Something wanton, that thrives on his tongue, yearns for the way his fingers hold to your hips, keeping you steady amongst your wriggling. He makes you his, he makes himself yours.
His cum in your system does you no favours, it heightens your senses, increases the sensation of his touch, until you're trembling, until you're pulling at his restraints, begging for him  to consume you whole and leave nothing behind.
When he's done, he holds you tightly, to his warm chest, little puffs of air disturbing your hair while you drift easily into sleep, his tail wrapped securely around your thigh, reminding you that there's nowhere on earth you can go, where he cannot find you.
It's the best feeling in the world.
~
When he wakes up in the morning, he's eager to make the apartment yours. He uses his influence to move all your things over from your old apartment, he even cleans and replaces any furniture he doesn't think you'd like. Perhaps it would be a good idea to go shopping too, to get anything extra you'd like.
Billy finds himself smiling while he whisks eggs.
~
"Mistress," Billy murmurs in your ear, his hands snaking over your hips, your amusement and affection increasing, "I can tell how much you like it. Please let me buy that lamp."
You study the blue stained glass lamp a second time.
"It's just too much Billy I couldn't possibly-"
He groans, spinning you on your heel to pinch your chin and bring you in for a kiss.
You sigh, happily, uncaring about the public space you were in, too caught up in your delectable demon to care. You throw your arms over his shoulders, standing on your toes, you feel the way he delights in rubbing his tongue against yours.
"Life is too shitty for you to deny yourself the things that you want." He says when he breaks the kiss.
You laugh, wondering idly how you let him convince you to leave the apartment for long enough to get anything done.
Your eyes crinkle, bumping your nose against his. Yup, you definitely wanted to take him somewhere secluded so you could jump him.
He groans again, catching the general idea of what you were thinking.
"I meant the lamp." He tries to clarify.
"Of course you did." You tease.
he rolls his eyes, pulls away from you to find a sales clerk.
Somehow, even after buying so many things, you don't even have to haul it out of the store, Billy handles everything, from paying to delivery arrangements, he gets it done, and all you had to do was pont at items and they were yours.
Ours, you think, turning to look at him, busy writing something down.
Because as insane as it might sound, you wanted to share your life with him, permanently.
You only wonder if that's something he wanted too.
While he's giving the woman at the counter payment and delivery instructions, you begin to turn in boredom to look around, accidentally bumping into someone as you move.
You smile, murmuring apologies, and they do the same politely before walking off.
A vaguely familiar masculine voice calls your name in surprise, and you turn, your stomach dropping as you catch sight of your ex- best friend.
The taste in your mouth sours as Dimitri approaches, the last interaction you had together springs to mind as if it's just happened, as if it was just yesterday he was calling you a 'spiteful bitch' because you wouldn't have sex with him.
Distaste shivers down your spine as he smiles at you. You take a shallow breath, mouth forming into an abrasive smile in hopes of warding him away.
It doesn't work, he only gets closer.
You freeze when he moves to hug you, pulling up short as his eyes make contact with something- or rather someone behind you.
"Who's this?" he asks casually, referring to the six-foot demon man ready to rip him limb from limb if he tried to touch you again.
You swallow nervously.

Another NSFW excerpt for you?
"Mistress," he murmurs, "I'd appreciate your patience while I explore your body. It's not every day that one gets to explore his willing charge."
You groan as his tongue snakes from your nipple to your neck.
"You're being mean." You gasp out, one hand drifting up into his hair.
"I know. Isn't it fun?"

Demon!Billy making out with his girl on the couch and wrapping his tail around her leg so she can't leave (affectionate)
Demon Billy's tongue literally invading her mouth, rough and sloppy and when she wants to pull back to breathe he barely lets her get a breath in before his mouth us on hers again. When she wriggles too much he holds her wrists down to keep her in place, it almost feels like the literal consumption of her soul.

Hi guys
Demon Billy NSFW teaser below the cut:
Without thinking, you reach down and gently take one of his horns in your grip.
When he stops moving, you look down at him in concern that you make have crossed a line.
Instead, he looks at you with so much heat in his eyes that it floors you.
With half-lidded red eyes, he reaches for your other hand, wrapping it around his other horn.
"You better hold on, baby." He says, leaning down to continue licking you.
