A Contract

Celestia takes in a deep breath as she sits in the massive throne room with her sister Luna to her side, not looking forward to her contract she had signed with the Alicorn of Death to ensure that Alicorns, such as Cadence, her sister Luna and herself immortality. She knows she’s not looking forward to it, but if it means spending ten years every millennium to ensure immortality, then it would be worth it.

"Sister... why must you do this with Death? Why not let it be me and save yourself?" Luna asks as she looks up to her older sister with worry in her eyes. Ever since hearing of Celestia's plan to ensure their immorality, she had been torn; part of her wanting to live, but the other part fearing for her sister.

“It is to ensure you, along with Cadance, Twilight and myself immortality for the next thousand years. I did it voluntarily, so you need not worry about me sister,” the regal pony replies. “You know what to do while I am gone?”

"Yes sister. I know what I must do," Luna says softly as she meets her sister's eyes and then nods her head. "When should Twilight arrive for you to tell her of your... servitude?”

“She should arrive any moment now.”

Luna nods her head again and then shuffles her wings, not out of nervousness but out of fear of seeing the figure of Death again as the door opens slowly and she stiffens up while locking her eyes on the large double doors.

Celestia maintains a straight face as she sees a tall hooded figure slowly make its way up the large room and up to the thrones, stopping shy of the two regal sisters, ordering the guards to stand down. “Death… We meet again…” she says with a dry tone.

"My sweet Celestia, as radiant as always," The figure says with a low but sweet voice as a gasp is heard behind him causing them to look back at the doorway. "You must be Twilight Sparkle yes?”

“Princess! Hold on! I’ll protect…!” Twilight suddenly says, the hooded figure near Celestia with Luna holding a hoof up at her.

"No need to 'protect' them from me, miss Sparkle. Celestia here has a contract with me that I am here to collect upon," He says as his horn glows gently and a scroll slips from the darkness of his cloak and floats before Twilight.

Twilight’s horn powers down as she begins to read the note:

‘I, Princess Celestia of Equestria, herby serve Death for the next ten years to ensure all Alicorns have immortality for the next millennium. I sign this contract on my own free will and will obey every command he gives me.

Signed,

Princess Celestia’

"I understand that this may be a bit of a shock, but she and I have a contract to go by," He says dropping the contract by Twilight's hooves. "You know what to do by now don't you Celestia?" He asks as he pulls out from under his cloak a maid's outfit with a few hair ties for her.

“Yes… I do.” Celestia’s horn glows softly, lifting her royal regalia off of her body, setting it on her throne as she levitates the outfit towards her, putting it on her, the end of it barely covering her flank. She then takes the ties in her aura as she works her normally flowing tail into a proper bun with some of the ties and uses the others to lift her tail up, showing off her love holes. “Happy, now?”

Death goes behind her and inspects her vibrant pink pussy and puckered tailhole, making sure they were on display at all times. ”Yes and I must say you look sexier in it each and every time that I see you wear it," He says with a happy tone to his voice before pulling out a collar and a leash from under his cloak and holds the end of the leash so the collar was hanging about neck level for her. "Now come to me Princess.”

“Yes… sir,” Celestia replies, feeling a bit humiliated at her replying to Death in that tone of voice, slowly following behind the figure, taking one last glance at Luna and Twilight before looking forward, passing some guards as they exit the throne room, their eyes, looking at Celestia’s… revealing outfit.

"How have you been while we've been apart, my fair Princess?" He asks as he buckles the collar around her neck, before they had walked out the main door of the castle and out into the main section of Canterlot, ensuring that the ponies there would get a sight before she disappears for a decade.

“I’ve been fine. Taking care of Equestria as best I can,” she replies to him in a dry tone.

"Good. From what I've seen it's like things have thrived since we last crossed paths," He says as he turns back to look at her, seeing that she wasn't at all phased by what she had to go through right now. "Tell me Princess, how long has it been for you since you last had something not made of latex or silicone under your tail?”

“Quite some time. They don’t tickle my fancy that much, to be honest.”

"Oh I would imagine. Now let's not waste any time here. I have many plans in store for you this time around," He says as he the cloak slowly separates and his large bony wings emerge from the darkness of his cloak. "Shall we?”

“Like I have a choice in the matter?”

He chuckles and then folds his wings. "Lighten up Celestia, after all if you're going to be this way I may just consider our contract null and void.”

She huffs softly and rolls her eyes. “Okay. Shall we head back to your place… Master?”

"That's the spirit my pet," He muses and then his horn glows again as his magic forms around them and in a flash they vanish from Canterlot.

Getting Started

“I see much hasn’t changed here since I was here last time,” Celestia says, following Death as he leads her towards his residence.

"It hasn't but I don't have much taste when it comes to fashion," He admits as he pulls down the large gate of his stone castle and then leads her across the wooden bridge and pulls it up behind them once they had crossed, ensuring that she wouldn't be able to leave until he opened it himself.

“I kind of had that feeling when we first got here.”

"Well maybe while I have you here this time, you can offer some advice to make this place more homey to you when you're here next. As a kind Master, it's the best I can do," He says with a happy tone to his voice as he leads his pet down the long hallways of his castle before coming to his own throne room, the light of the sunset shining through the tall and open windows.

Celestia looks around the throne room, the rays of sunlight coming through. “I must admit, the sunset light is pretty in here.”

"Yes it is, I find it lightens things up. Ironic considering who I am but I find beauty in irony," He says as he pulls her leash back, stopping her just on the right of his throne as he takes his seat and slowly pulls off his cloak, revealing his skeleton body under the black cloth.

“It seems you haven’t changed much either,” she grins, not being phased by his skeleton body and head.

"Of course I haven't changed. But I think that I've been a bad host. Would my pet like a drink?" He asks as he lifts a goblet off of a wooden table resting against the wall beside his throne and holds it before her.

“Thank you, Master,” she says “kindly” to him and takes the goblet to her lips and drinks the sweet liquid, tasting like berries.

He smiles as he watches her drink down the wine he had given her. "How does it taste, my sweet pet?”

“Tasty, Master. Something like berries.”

"It's one of the finest wines I've ever tasted. I knew I would want to treat you to something nice before you truly began," He says as he lifts her chin and gives her a smile. "There is one thing I forgot to mention about your drink; I enchanted it to put you into a mind blowing heat that won't be easily sated.”

“It… It what?” she begins to ask before her nether lips begin to tingle and become moist.

"You heard me my pet. And it should be kicking in... now," He says with a grin as he sees her face flush red under her white fur.

“Y-You monster…” she moans and sits on her flank as her hoof, seemingly to have a mind of its own, drifts towards her pussy to rub it, the heat becoming too great for her to ignore.

"Watch your words with your Master my pet. Don't want this heat lasting all ten years do you?" He asks and then leans in and licks her lips gently with his tongue.

Celestia shakes her head as she rests it back before beginning to rub her lips vigorously with a hoof.

He smiles and looks down at her hoof rubbing her own pussy so hard and fast he could see her juices flying form the underside of her hoof and from her lips. "Looks like somepony is going to cum without Master's permission.”

The Alicorn in heat moans as she continues to rub herself quickly, panting as she tries to get over her heat, but the heat continues to increase with each passing moment.

"Enjoying your heat, Celestia? I specifically designed it so it will nearly drive you nearly mad with desire.”

“Nnnngh!” she groans, continuing to rub herself, nearing what would probably be one of many orgasms as long as the unexpected heat cycle keeps up.

"Enjoy yourself. This is literally only the beginning of it," He says with a grin as he gets up from his throne and walks out of the room, leaving Celestia tied by her leash to his throne.

Celestia groans as she soon experiences her first orgasm as she squirts her juices onto the floor, panting heavily as her juices cover her hoof and her haunches.

As he listens from the side of a hallway that was out of her eye sight, he uses his magic and lets a disguise cover his body, making him appear as a normal but very handsome stallion. "Wonder how she'll respond to this little trick.”

“Nnngh! Have to… rub this out! It’s too… much for me!”

"Maybe I can help you Princess," Death says as he steps into view again, the disguise he wore had a long flowing mane of golden yellow and white fur, nearly as pristine as her own.

“H-How did… you do that? Y-You’re just toying with me now!” she replies, unable to resist his charm for some odd reason, her haunches still heavy and wet with heat.

"Who says I'm toying with you my pet?" He asks as he steps toward her slowly, making each movement as irresistible as possible.

Celestia remains silent as she continues to rub herself, her heat growing stronger with each movement of his.

"If you beg me then maybe I'll help you with that heat of yours," He says as he walks up to his throne and then lifts her hoof away from her pussy and holds it away with a flash of his magic, his magic acting as a cuff.

She groans, trying to move her hoof towards her lips, but is unable to; the heat making her mind slip into an extended state of ecstasy.

"Just beg me and I'll help you. I can feel your lust growing with each passing second. Soon you won't be able to do more but beg me to help," He says softly as he leans down toward her pussy and gives it a gentle but quick lick.

“You… You… You have to help me! Please help me!” Celestia asks him, the heat proving too much for her to ignore.

"Come now Princess. I've heard you beg better last millennia. I know that you can do much better," He replies with a smirk, and then gives her pussy another quick and teasing lick, tasting her sweet juices…

Her pants grow heavier and more labored, the heat nearly making it impossible for her to talk. “F-Fuck me… Fuck me like… a little maid whore… I… I need you!”

"Better, now present yourself and let me claim you again like before," He says and gives her flank a smack with his hoof, grinning lustfully at her.

Without a moment of hesitation, she raises her flank and lowers her chest, her raised tail to the side, revealing her dripping pussy and tail hole to him.

"Good girl," He replies and pats her flank with a hoof and then mounts her and pushes his cock against her pussy and then slowly thrusts inside her dripping pussy, moaning gently.

Celestia groans as his cock slowly enters her wet and heated lips, wanting him to fuck her hard and long until her heat was satisfied.

"Now we go at my pace, unless you can convince me otherwise," He breathes into her ear gently before pulling out till only his head was inside her then thrusts back into her, his balls slapping against her flank.

“B-But Master… I’m in heat!”

"Then you... should start begging..." He moans and then repeats his movement, with just the same pace that he had last time, taking her to the hilt with one hard thrust.

Celestia pants heavily, her tongue hanging out of her mouth as she still feels Death inside of her. “M-Master… fuck me… a-and cover me with your… cum… Make me a… a naughty maid and… let me kiss… your hoof!”

"Good girl..." He moans as he closes his eyes and thrusts deeply into her and then as he pulls out he swivels his hips before thrusting back into her roughly and slowly picks up his speed inside her. "Keep talking my pet.”

“Let me lick… your hoof and serve… you well… M-Master,” she continues, in a lustful trance, the heat making her talk like she is.

He smiles and then lets out a moan of pleasure before sliding his hoof along her back and slides it against her neck as he pulls out and then thrusts back into her tight pussy with swift thrusts. "You may…

“T-Thank you Master! Use my body t-to your liking! Fuck me good!”

"Better my pet..." He moans and closes his eyes before pulling completely out of her tight pussy and then slams forward, his cock pushing easily into her tight tailhole, forcing a groan from Death from how tight she still was there.

Celestia lets out a lustful groan as she feels his cock in her tight tailhole, feeling it move easily from her pussy juices lubricating it.

"Da-Damn! You're so fuck-fucking tight!" He moans deeply and then presses his hoof against her muzzle, effectively gagging her and forcing her to lick his hoof as she said she would.

The Alicorn moans and licks her Master’s hoof with her tongue while he muffles her moans as he pounds away at her tailhole.

"I'm go-going to wreck you puss-pussy and tai-tailhole so hard!" He moans deeply and then slams deep into her tailhole, slapping his balls against her pussy, earning a deep moan from her throat.

Muffled moans come from Celestia’s mouth as she continues to let Death use her holes as she licks his hoof covering her muzzle, serving her master like a good maid.

With a new idea in his lust filled mind, Death begins alternating between her two holes, sinking deeply into one before pulling out and sinking deeply into the other. "That's a go-good maid... letting your Master do what he ple-pleases to your body.”

Her juices from her pussy drip onto the floor beneath them as her eyes flutter from the extreme pleasure he was giving her between her love holes.

"You ma-may cum if you can my pet... I know you're trying to la-last longer. But real-really what's the point? Th-This heat has to be eating you up..." He moans deeply into her ear before hilting deep inside her pussy and unleashes a torrent of cum deep into her dripping pussy.

Celestia groans deeply as she feels his seed fill her womb as she cums around his cock, her lips tightly wrapping around him.

"Good maid... you-you're going to have one hell of a me-mess to clean when we're done here..." He moans and then starts slowly thrusting into her pussy, pushing his cum deeper into her pussy.

The Alicorn shivers and she begins to see stars as she is begin filled with his cum, the heat still itching at her loins.

Slowly he lifts his hoof from her muzzle and then wraps his foreleg around her neck and uses his new grip as leverage to fuck her harder and deeper than before.

Celestia lets out short and sharp groans as his hoof wraps around her neck, making her pussy wetter.

"Ju-Just what I like... A slut wh-who knows her place; at her Master's hooves and beg-begging to be fucked.”

“Hmmm! Hmmm! Hmm, yes! Oh… fuck me Master…”

"Just like I wanted..." He moans deeply and then pulls nearly all the way out of her tight and cum filled pussy before thrusting back into her with quick and deep thrusts.

—

Celestia weakly kneels before her Master with her front hooves curled in front of her with her mouth open wanting his cum in her mouth after having numerous orgasms herself with eight from her master, six being in her pussy and the other two in her tailhole. “M-Master…?”

"Y-Yes my pet?" He moans softly as he fucks her tailhole roughly, making each thrust deep and as slow as possible to draw out the pleasure she was being given.

"Y-Yes my pet?" He moans softly as he pulls his cock from her muzzle, having filled her muzzle with another of his long orgasms, his cum leaking from her muzzle like her pussy was before he fucked her.

“G-Give me one more please? I-I’ll swallow every drop!” she pleads with him as she swallows the few drops of cum that was on her tongue. “I won’t swallow until y-you tell me to…”

"Of course my pet, now open wide and I hope your skills in deep throating are still there," He says as he steps over her, his cock pressing against her nose. “Lick."

Celestia nods obediently and licks his head softly with her tongue, tasting beads of his cum.

He moans deeply and closes his eyes as he rubs the back of her head with a hoof, feeling her silky mane beneath his gentle hoof. "Good girl.”

The Alicorn nods softly before tilting her head forward, only taking his head into her mouth, licking on his head with her tongue.

"All the w-way down pet. Just as I like.”

She nods and presses her muzzle against his crotch, feeling his long cock travel down her throat.

"Goo-Good girl... st-still have that skill. I wo-wonder how you ke-kept it so re-refined..." Death moans deeply and then presses against the back of her head and thrusts as deep into her throat as he could.

Celestia gargles softly as his cock is rammed down her tight throat, suppressing her gag reflex as her eyes water from him fucking her throat.

"Good girl... th-that's such a go-good girl..." He groans softly and then holds himself deep inside her throat.

The princess groans as his cock cuts off her ability to breathe, her lunds start to cry out for air. She tries to pull back, but Death has her locked to him, his cock buried in her throat.

"Not y-yet..." He moans deeply before letting out a groan as his cum shoots from his cock and straight down her throat.

The Alicorn swallows as best she can, his cum shooting into her belly, leaving every hole of hers now full of cum.

Quickly he pulls back from her throat, letting her get breath back into her lungs after being deprived of air for a little while.

Celestia pants heavily and swallows, looking at the ground before looking at Death in his disguised form.

"Did my pet enjoy her treat?" He asks with a groan as he feels his cock throb from his many orgasms in the day.

“Y-Yes Master…” she replies obediently, kneeling before him, her legs weak from the orgasms she was given.

"Good, because this is only the beginning of your contract this time," He smiles and then leans down and looks into her eyes.

“I… I understand…”

"Now..." He begins as his disguise fades away and he looks into her eyes. "It may be late, but I think you've earned some rest. Come with me," He says and takes the end of her leash with his magic and gives it a tug.

Celestia follows behind Death, trying to keep her balance, stumbling a few times from how sore her pussy and tail hole were from being stretched by his cock.

"Now I do have a surprise for you this time while you sleep, unlike the other times," He says with a grin of satisfaction of seeing her stumble and try so hard to stay standing.

“Y-You do?”

"Yes I do. But for now let's make this interesting," He says and stops her short of his bedroom door. "Close your eyes.”

She obediently does so, not sure of the “surprise” Death has in store for her this time.

He slips inside his room and returns with a long piece of black cloth and ties it around her eyes and then leads her into his room, making sure she wouldn't run into anything he had set up.

“What is… this for Master?” Celestia asks, feeling the cloth cover her eyes.

"Don't worry yourself about that my pet," He commands and then leads her up onto a comfortable bed and pushes her onto her back.

The blindfolded mare rests on the bed obediently and feels the cold, yet gentle touch of her Master at her side, making her shiver softly.

As he looks down at her form, he crawls into the bed with her and then breathes in her scent with a smile. "You know my pet... this is only the beginning.”

“O-Of my contract with you?”

"You'll see my pet. You'll soon see.”

Earning a Reward

(A Few Months Later…)

‘Have to… hold on! I… have to… resist… cumming!’ Celestia thinks to herself as she undergoes an exercise in resisting temptation to cum as she is in an almost painful heat and has a small vibrator in her pussy, her hooves shackled above her head to not let her rub herself.

"That's a good girl," He says as he sits and watches her from his throne, seeing her pussy dripping with her juices like a small waterfall. "Don't cum my pet; not until I tell you to.”

“Y-Yes Master! It… hurts not… to come!” she groans at him, seeing him in his pony form, stroking his big cock for her to tease her.

As he slowly strokes his hard cock in front of her, he uses his magic and fondles his balls letting out a low moan. "Too bad my pet... you're not go-gonna cum yet.”

Celestia shakes her head obediently, trying her hardest not to cum without her Master’s permission. She has gotten better during the first few months of her contract, but she has cum every time without his permission and received punishment each time, one of them being spanked hard on her flank until it was red. She knew it hurt, but knew it was encouragement also to obey his orders in order to get his cock inside of her while she was in heat again.

"Just remember my pet. If you want your reward, you have to last," He moans happily and then lifts a flogger with lots of firm leather tails. "I would hate to use this so soon.”

“I… I don’t want to be punished… nnnn, Master! I… learned from last time and w-want to make you happy!” Celestia says to him, not wanting to use it on her flank again.

"Good, you're learning very well how to please me. Soon you'll earn that orgasm I will give you.”

“T-Thank you Master! Thank you!”

"You're we-welcome my pet... now let's up the ante," He says as he uses his magic to put down the flogger and then picks up the remote for the toy buzzing inside her pussy and turns it up slowly.

Celestia pants heavily as she feels the toy vibrate faster and faster inside of her, nearly making it impossible for her not to cum this instant; but she had to hold it in order to avoid another punishment from her Master.

"Don't cum. Don't cum my pet!" He commands and then strokes his cock faster with his hoof.

She shakes her head, not saying she can’t hold it any longer (which she couldn’t… barely,) but saying that she will not cum until instructed.

"Almost... almost there," He replies softly and then looks into her eyes. "Cum my pet.”

The bound Alicorn then lets out a scream and thrusts her hips forward and squirts a solid fountain of her juices a good distance away from her, as she finally is able to release her orgasm with her Master’s permission.

He walks up behind her and then presses a hoof to her pussy and rubs it as fast as he could, prolonging her orgasm and making it that much better for her as he feels his cock throb with the desire of seeing her cum with his permission.

She groans loudly, still enduring her best orgasm of her life now, shooting her juices for another solid thirty seconds or so before the stream starts to weaken.

"Oh is my pet's orgasm done already? I was hoping that you'd break your record from the second time you came to me.”

She pants heavily, looking at him with a small grin on her face. “Was… Was that… an order too, Master?” she weakly says to him with a chuckle.

"For that comment I will make sure that you beat your record. With my cock and your new toy," He says with a smile and then kisses between her wings and then rubs the maid outfit she was still wearing.

“I’ve… longed for… your cock so much… Master!”

"Good... now should I fuck you right here or..." He pauses and then looks around the room. "Does my pet want to try something a little new?" He asks with a teasing tone as he keeps rubbing her pussy.

“W-What… do you mean by… ‘new’ Master?” she asks curiously.

"Then I think we should try something new," He says as he uses his magic to slowly undo the cuffs around her forelegs and then helps her onto her forelegs. "You ok my pet?”

“I… I think…” she replies softly, barely able to stand from her orgasm before plopping onto her belly, her hooves too weak to support her like a newborn foal trying to trot for the first time.

"I guess not," He chuckles and then his magic focuses around her body and lifts her into the air as he walks over to a nearby bench and lays her on the bench and then traces her flank with a hoof as he binds her to it using leather cuffs.

“T-Thank you Master…” she says, grateful for being carried by him and strapped into the bench.

"You're welcome my pet. Now rest and let your Master work you up to your longest orgasm ever," He moans and strokes his cock with a hoof.

“Of… Of course…”

He smiles happily and then walks around behind her and then mounts her flank, having already given it a gentle smack. “Ready?"

Celestia nods softly to him, turning her head back to look at him with an eye.

"Good girl," He replies and then thrusts his cock into her tight pussy slowly and wraps his forelegs around her belly and breathes lustfully into her ear.

The Alicorn moans as she hears him breathe into her ear, turning her on and making her wet already.

"The heat doing anything more for you?" He moans softly before slowly pulling out of her pussy till only his head was inside her before thrusting back into her roughly.

“It’s… It’s mostly your… breathing that’s… turning me… on Master…” she moans, feeling him thrust deeply into her slick and wet pussy.

"Is that ri-right?" He asks softly as he slides his tongue out and licks her ear softly as he thrusts back into her after repeating his previous motion.

“Y-Yes Master… Oh yeah…! Mmmmm…”

He moans happily and then sighs happily into her ear as his magic massages her flank.

Celestia lets out a soft groan as her Master fucks her lovingly and feels his cool magic massage her bare flank.

"Now... mo-moan for me. Like the slut we both kn-know you are..." He moans dominantly into her ear before pushing forward and then bites her ear between his teeth.

She obediently moans for him, loving how his thick cock rubs against her wet pussy walls, missing the feeling of him inside of her. “Hmmm, Master… You feel so good.”

He groans deeply and then hilts deep inside her cunt before slowly rocking his hips, adding to their pleasure as he closes his eyes to enjoy the feeling of her dripping wet pussy around his cock.

Celestia closes her eyes also as her lips wrap around his cock, her juices dripping onto the floor beneath them, her body filled with pleasure as he fucks her lovingly.

'She's so tight even after all th-these years... I don't know ho-how she's doing it but... I love it!' He thinks happily as he scratches her ear with his teeth.

‘He still has got those moves to make me soaking wet in ways no regular stallion can with me. I think I’m addicted to him…’ she moans to herself, moving her flank as he gently slaps his balls against her wet pussy.

As he feels her move beneath him, slapping his balls against her body, he groans into her ear as he feels his cock throb inside her from her display earlier.

“Hmm, you feel so good inside me… Master. Oh fuck…”

He smiles at her compliment and then pulls back as he feels his cock get a breeze from the cool air in the room before he slams back into her, feeling the incredible warmth nearly make him cum on the spot.

“M-Master… cum inside me! Release your seed into me! I… I want your cum!” Celestia groans, nearing her second orgasm, feeling the deep, hard thrusts inside of her.

"Not ye-yet my pet... I wan-want you to cum again," He groans happily as he feels his cock throb.

“O-Ok… I’m… so close though!”

"Go-Good... now you ma-may cum fr-freely, at least unti-until tomorrow," He moans happily as he buries himself back into her so that all of his cock was consumed by her pussy. "Oh fu-fuck!”

“I-I’m cumming Master! I cumming!” Celestia announces loudly before squirting her juices around his cock, making her pussy tighten like a vice around his cock, sending him over the edge.

He groans loudly into her ear as he shoots his cum deeply into her pussy as it grips him tightly, milking him for his cum as he uses his magic to force the orgasm of hers to last longer.

The bound Alicorn groans loudly as her orgasm lasts longer than expected, continuing to milk his cock for his cum, shooting deep into her womb. As her orgasm continues on, starting to get close to the longest she had ever had under his care he releases his spell, knowing that he had prolonged it enough for her to get close enough, his cum being sucked from his cock like a mare sucking on the straw to a milkshake.

After for what seems like an eternity, Celestia feels nearly all the energy in her body drained from the prolonged orgasm, her breathing becoming heavy as her heart beats against her chest.

Even her Master collapses on top of her and breathes heavily into her ear, his body even taxed from her orgasm milking him and his pounding that he had given her. "I fe-feel your he-heartbeat…"

“Y-You do Master?” she asks softly.

"Y-Yes my pet... I feel it al-all over your body," He replies softly and then kisses the base of her ear. "You dese-deserved that my pet…"

“T-Thank you for being so… kind Master… I am ever grateful…”

"Yo-You're we-welcome. Ho-How do-does my cum feel in-inside you?”

“Amazing. S-So warm and comforting. It’s… been a while since I’ve had warm cum inside me…”

"Le-Let me gu-guess... I was the last to fi-fill you full of it?" He asks softly as he tries to pull himself from her pussy and feels her pussy lock around his cock tightly, causing them both to groan deeply.

“Y-You could say that. M-My sister and I have… had fun with f-fake cocks, but… I’ve missed a real one inside me so much…”

"I ca-can tell... Y-You're the only immortal being to m-make me cum this much..." He admits with a smile that she couldn't see before finally managing to pull his cock from her and allows his disguise to fade away.

“Oh? Really now?” Celestia asks before she feels the restraints slowly fall from her hooves.

"Yes," He replies as his magic undoes her restraints. "When you can move I want you to clean this room up with your tongue like you would my cock. Then when you finish, have another goblet of the wine and return to my chambers. I will have a surprise waiting for you.”

“Understood Master…” she replies, slowly getting off of the bench and softly plopping onto the ground near her juices, already cleaning the floor up with her tongue, like a good mare that she was.

"You're a good girl," He replies as he kneels beside her and then rubs her cheek with his hoof before getting back to his hooves and walks out of the room with a satisfied grin on his face.

Celestia continues to clean the floor of her juices with her tongue, enjoying her sweet flavor along with his slightly tart flavor until it was all clean. She then gently gets to her hooves, stumbling a few times before exiting the room and hugs the wall for support as she makes her way to Death’s chambers.

As he rests on his bed, looking out the window overlooking a large expanse of water that was roiling from a coming storm that was many miles away he turns to the door as he hears it creek open. "My pet, is the room clean?”

“Yes Master, just as clean as your cock after a brutal session with me,” she replies to him obediently.

"Good girl. I'm happy to hear. Now before you join me in bed tonight, I want you to partake in the wine once more like usual. However you won't be bound, you'll only have to do one thing.”

“W-Which is what Master?”

"You only have to cuddle with me. The sound of a storm is relaxing, and spending that time with you will be even more enjoyable," He says with a poetic way of weaving his words.

“S-Such a way with words, Master…” Celestia blushes softly as she slowly approaches the bed, crawling next to him, lifting the goblet on her side of the bed to her lips, drinking it greedily before setting it on the stand next to her side of the bed.

"Thank you my pet. I often do enjoy writing a little poetry from time to time and sometimes I notice that it comes at the strangest of times. Now one last thing," He says as he lifts a smaller vibrating dildo with his magic before gently guiding it into her pussy and buckles a strap around her thigh.

“M-More of me cumming, M-Master?” Celestia asks, feeling the small orb enter her wet lips, vibrating on the low setting.

"No cumming, just teasing," He replies as he looks into her eyes with his own empty sockets before turning back to the window that was to her back.

"Would you like me in my other form?”

“Y-Yes please, if you don’t mind…”

"Only for you," He replies as his horn glows again and his form of a white stallion is the one holding her as he turns her so that she had her back against his belly and chest while he could still hold her and see the coming storm clouds. “Better?"

She nods softly. “T-Thank you Master…”

"You're welcome. Now relax and enjoy this night. Stormy nights always amaze me with their beauty," He says as he hugs her close with his forelegs and then slides a hoof down to her pussy and rubs it slowly and gently.

Celestia rests with her Master and coos as he plays with her, feeling herself go into a mild heat with the vibrator inside of her teasing her also while watching the approaching storm from the large window nearby. As the storm rages on, millions of Death’s fertile sperm cells were swimming through her body before one of them found her egg and implanted itself inside it, starting a life within her.

Epilogue: Soon Enough

(Several Months Later…)

"I still can't believe that you're pregnant with our foal my pet," Death says to Celestia softly as he rubs her belly gently with a hoof as he kisses the back of her neck. The two of them resting together in his bedroom, his pet now being only about halfway through her pregnancy while a small vibrator against her pussy lips buzzed away lightly.

“I know. I think it was the day when I had that long orgasm when I held it in until you commanded me to cum,” she grins, nuzzling her Master softly while she coos with the vibrator buzzing away.

"I think that is right. How far along you are fits the timeline well," He replies softly and then reaches up with his muzzle and licks the base of her ear softly.

She moans softly, feeling him lick her ear. “Y-You naughty stallion you…”

"Is that anyway to talk to Master?" He asks gently before giving her horn a lick. "Now stay here my pet. I have a feeling that I have something here to attend to.”

“Of course… Master,” she replies slyly with a wink towards him, rubbing her enlarged belly, feeling a soft kick with her hoof.

As he rolls off the bed he walks up to the door and looks back at her with a smile on his lips before he sheds his spell becoming his skeleton self once more before slipping out of his room and walks into his throne room and sees a rolled up scroll resting on the seat.

He unrolls it and begins to read it:

‘I, Twilight Sparkle, Princess of Friendship in Equestria, herby serve Death for the next ten years to ensure continued longevity amongst my friends. I sign this contract on my own free will and will obey every command he gives me.

Signed,
Princess Twilight Sparkle’

"Princess Twilight Sparkle... offering yourself up to me to keep your friends alive? That's very noble of you, but I think you'll do well serving unknowingly along side your old teacher.”

Death chuckles softly to himself, knowing, sooner or later, that she would come around and see things his way. He promptly writes a response to her, indicating the date the contract would begin and sends it off. He then leaves his throne room and trots back to the bedroom, changing forms along the way as he enters the bedroom with his pony disguise seeing Celestia on the bed, eating some fruit.

“That certainly didn’t take long,” she indicates, seeing him back so quickly.

"No it didn't. But now I think that cuddling with you is in order," He replies and crawls back into bed with his pet before pulling her close to him, her back resting against his belly.

“Hmm, I couldn’t agree more…” she grins, using her gentle magic to guide a hoof of his over her belly.

He smiles as her warm magic grips his hoof gently and then he voluntarily rubs her belly. "I still can't believe it. You're carrying my foal…"

“I am… Master. I never imagined becoming a mother before…” she replies before guiding his hoof to a spot and feels a gentle kick.

"Oh! Our foal just kicked!" He replies happily and kisses her ear softly.

“They did! They must like you already!”

"'They?'" He asks as he rolls her over and looks into her eyes. "How are you guessing you are carrying more than one?”

“I know I’m only carrying one, silly!” Celestia replies, booping his nose softly. “I said ‘they’ because I’m not sure if it’s a colt or a filly.”

He smiles and then kisses her lips softly, while still rubbing her belly with a hoof. "I hope our foal is a colt.”

“Why a colt? Just because?”

"Because I've always wanted to have a son.”

“I see. Would you still be happy if it was a filly, still love her as much as you would a colt?”

"Yes I would my pet. Filly or colt I'll be happy, especially since my beloved pet is carrying him/her now.”

“Hmmm, I’m happy to know,” Celestia grins warmly and nuzzles him. “Will you have your pony form on while you are around them, so you don’t scare them?”

"Of course my pet. Unless they come out like how I normally look.”

“Maybe. We’ll see then, hmm?”

"Yes we will my pet," He replies with a smile and then kisses her lips, knowing that soon her old student would be serving him soon enough.
