Celestia always had some of the most awful bedhead the world's ever seen, but it was her day off and no one would care. Well, as much as postponing her duties until the afternoon was a day off. She and her sister had spent Hearth's Warming Eve under a blanket next to the fire, watching the snowflakes drift from the heavens. She could still taste the traces of coco on her lips.
She removed herself from her bed and stretched. Being ethereal, her mane would sort itself out in time despite it looking like a rat's nest met a grease fire. She stretched her arms and wings to the max and heard a series of delightful pops.
"I hate morning..."
Goddess of the sun or not, that meant she had to wake up for the day. The day was fine, but waking up required caffeine.
"Coffee..." she moaned.
Celestia strode out of the room clad in not a single patch of cloth. Her own staff were well aware of her lack of interest in wearing clothes around the castle, but now they had no one to blame but themselves. All of the hearths were lit and during the night, and she woke up at three swelteringly hot.
Rubbing the sleep out of her eyes and striding past a blushing maid keeping her eyes firmly in front of her, she walked until she reached the sitting room.
"Always keep it stocked for late night snacks."
Kitchen staff kept fresh cookies and snacks around for Luna's restless wanderings but if they were there, they were fair game for her as well. Several different kinds of sweets sat on a large oak table" ting-a-ling, frosted cookies, candied orange peels, peppermint sticks, chocolate and caramel turtles, sugar cookies, brownies.
Celestia turned around to look at her large butt and love handles. She swore her ass was still jiggling just from having walked to the table.
"If they're worried about the royal butt, then they should stop feeding it."
She shoved a frosted cookie in her mouth, followed by a handful of ting-a-ling. Her hand froze around a handful of peppermint sticks.
The sitting room had been decorated for Hearth's Warming along with the rest of the castle. Nothing ostentatious, only functional decorations when applicable, but there were a few places in the castle, such as the sitting room, that weren't heavily trafficked. A single spruce tree hugged the far wall next to some bookshelves. Fake presents sat underneath and the tree was decorated with tinsel and bulbs.
What caught her attention was the snowman leaning against the wall next to it. More appropriately, the snowmare. Luna's cobalt fur contrasted with the bright, woollen shirt hugging her ample bosom and rounded abdomen. A size too small as it was, Luna's breasts squished together and revealed an eye-catching amount of cleavage. Red and white stockings hugged her petite legs, and the swinging length between them revealed that she was wearing nothing else. The only other stitch she wore was a red and white cotton cap with a bell hanging from the end.
"I wondered when you'd get up, sleepyhead," Luna said as she took a draft from a cup of eggnog. She dry heaved the moment it touched her lips. "What kind of cursed drink is this!?"
"Egg... eggnog..." Celestia said slowly, her eyes starting on Luna's chest and drifting south with each passing moment. Luna's breasts were swollen with her late term pregnancy, sensitive and ever expanding due to her growing foal. Her gravid stomach looked ready to pop due to her slender frame, and with the snowman shirt, gave her the appearance of a snowman with an especially weighty bottom. Even lower, Luna's half-flaccid black and mottled silver cock peeked out of her sheath while her scrotum swung with every twitch of her luscious hips. Celestia saw the barest hint of Luna's marehood hiding behind Luna's full balls.
Celestia was painfully aware of how dry her mouth was. Luna took the moment to saunter forward, each and every asset jiggling with every step.
"Problem, sister mine? Luna said as her snowman belly rubbed against Celestia's pudge, but the naked princess' attention was focused more on the hard and dripping object poking her thigh. "Presenting your nudity already? That's bold of you."
It was waaaaay too early in the day to deal with her sister coming onto her.
"S-sister, what are you—"
Luna held a finger to her lips. Those lovely azure eyes stood inches from her own, Luna's warm breath caressed her throat and giving her goosebumps.
"You've been wonderful to me ever since I returned. You helped me make friends, reintroduce me to ponies, and," Luna grabbed Celestia's hand and placed it on her belly, "you've given me the greatest gift I could ever ask for. So, seeing as it is Hearth's Warming, and I hadn't had the time to leave the castle and pick out a proper gift, I thought..."
Luna stood on her toes and kissed Celestia on the lips. She could taste the hunger and passion lurking just behind the kiss. Luna's member throbbed in time with her heartbeat, smearing precum over her naked thigh. Celestia felt her own marehood moisten and her own cock harden and slip from its sheath. Luna's own stallionhood had hardened as well and slowly crept up that ivory leg.
Celestia pulled away and looked to the side, her face flushing. "Luna," she whispered, half worried, half wistful, "not here. This isn't our bedroom."
"I can't help it. I'm in one of those moods," Luna giggled like a schoolfilly. She wrapped her arms around Celestia's waist and pulled her closer. Her sister had been increasingly amorous and cuddly as her pregnancy progressed, but now was something else completely. "And don't saw I am just being hormonal."
Celestia rolled her eyes.
"It's just," Luna continued, "I wanted to give you a proper gift, so why not..." Luna's hands drifted down and took a handful of Celestia's full ass. "Why not the same present you gave me for my birthday?"
Celestia's cock throbbed and prodded the undersided of Luna's belly. "Should I take that as a yes?" Luna said with a sultry smile. "Just think about it: us together, bellies full of babies, breasts full and ready for nursing. Every look at the changes to our bodies a message that says 'I did that.'"
Luna started dotting kisses up Celestia's collarbone, the lithe tongue licking and making her tremble with every caress.
"I want to see you full of my babies, sister, just as I am full of yours. When I give birth, I want you to plant your seed deep within me again so we can watch each other grow with life every day. I want to see your wide, stretched, foal-bearing hips. You're going to keep growing until you're the biggest mother Equestria's ever seen, bigger and bigger until your full of nothing but foals and my seed. I want to see you fuller, rounder, a goddess of fertility as much as the sun itself."
A hand wrapped around her twitching shaft and gently stroked it to its full hardness. Luna's cock was thicker, but Celestia's was close to a foot in length. Another hand gently squeezed her full and gurgling nuts before sliding down and cupping her copiously dripping marehood. A single finger teased her puffy lips and she moaned her need.
"I want to see you like me, sister. I want to see you panting and moaning and and grunting and screaming my name."
That finger pierced her lips without warning or mercy. Celestia's legs buckled and she wrapped her arms around her sister, her hips bucking against the most welcome intruder.
"I want to breed you."
Celestia mashed her lips against her sister's in raw, passionate need. Their tongues danced just as their cocks finally reached full mast and rubbed together like the lovers they were. Celestia's hands gripped Luna's slender waist and roamed over her belly.
"We made this," she whispered during one of the brief moments where their lips parted.
"And we'll make so many more."
Both of Luna's hands wrapped firmly around Celestia's now rock hard cock and stroked. She was large enough that there was plenty of room for both hands on her titanic shaft, and started to thrust her hips upward as her sister eagerly gave her a handjob.
"I'm wet and ready for you," Celestia whined upon feeling the emptiness in her cunt.
"I'll be playing with that in a moment." Luna thrust her hips forward and Celestia could feel the fat prick rubbing against her nether lips. "Right now, just come for me. Show me that baby-making virility."
Celestia watched as her plump sister got to her knees, removed her snowman shirt, and laid Celestia's cock between her milk-filled tits. A spurt of precum splattered again her chest fluff and Celestia's stallionhood throbbed. Luna pushed her tits together and sandwiched her sister's cock. She nuzzled the tip of the cock and licked up the pre gathering on the flared tip before sliding her boobs up and down the slippery length. Celestia admired that her cock lay perfectly between those perfect tits of her sister and rested below her chin as if it was meant to be there.
"I hope you'll enjoy your present."
Luna dragged her boobs down Celestia's shaft, dragging her tongue along the whole way. Back up, then down again, Luna licked her head every time and savored each drop of precum, sampling the rich taste of Celestia's dick. Celestia folded her hands around her sister's head and started thrusting her cock in time with Luna's strokes.
Luna leaned down and suckled the flare like her unborn child would nurse her breasts. Celestia moaned her approval and thrust her length into Luna's tight mouth. It was a constrictive fit, but Luna bounced her head on the shaft until it could comfortably sit in the back of her mouth. Celestia could feel her marehood soaking her thighs and delighted in rubbing them together, relishing the slick feeling between her legs.
A familiar pressure built up in Celestia's loins, the very same rushing sense of desperation that caused her to push her cock into her sister so far it kissed her fertile womb. Luna smiled around the stallion lodged in her mouth and blinked her eyes flirtatiously. The only warning she received was Celestia's flare swelling in the back of her throat and the explosion of marecum squirting forth from her hungry pussy.
Luna's cheeks instantly bulged as a thick shot of cum rocketed out of the throbbing cock. A hand went to her sister's balls and massaged them, delighting in feeling them draw up to deliver their load into her hungry mouth. With another spurt, her mouth was filled to the brim with her sister's hot spunk. Celestia's balls soon flooded her mouth and streams of white escaped her lips.
Celestia's eyes were closed, riding out her explosive orgasm that her wonderful and perfectly pregnant sister gave her. Luna leaned her head back a fraction of an inch and swallowed a meal's worth of cum. Celestia's hips twitched with every spurt of her cock, her grip on her sister's head like iron. The well endowed mare's balls clenched again and again until Luna's insides were pained as white as the snow.
Celestia leaned against the wall, panting, the head of her cock still stuck in her sister's mouth. She felt Luna's tongue snake around her shaft in circles, cleaning it off little by little. Despite her cock going flaccid, Celestia felt new life stir in her stallionhood upon seeing her flare stuck in her sister's mouth free itself with an audible pop. Luna opened her mouth and stuck out her tongue to show her a small pool of thick seed. She closed her mouth and Celestia's cock began to rise a little as she saw Luna swallow. Opening her mouth again, Luna showed her sister what became of the tasty treat.
She put both hands on Celestia's fat, jiggly ass and shoved her towards the table of snacks. Celestia crashed against the table with a cry of surprise. Hands circled her curves and hugged her back. Luna's belly rested on her ass while her hands stroked Celestia's slowly hardening shaft.
"I'm going to fuck you until you can't walk straight. I'm going to fill you up with so much cum you'll look as pregnant as me," Luna whispered sensually in her ear. The fat head of Luna's cock circled her marehood, probling just lightly. Celestia gripped the edge of the table to prepare to be mounted by the one and only stallion worthy of her.
"Breed me, my sister, my love. Put it in."
Celestia shook her fat ass at her sister and felt precum smear across her cheeks. The cock tickling her labia was incredibly stiff. A steady stream of pre dripped from her sister and glazed the masterful ivory butt before Luna's stallionhood wedged itself between her cheeks.
Then Luna's hips rocked forward.
Celestia gave her sister a moan of appreciation. She just wanted to be rutted senseless and feel Luna's cock against her womb, just as she felt her sister's.
"Don't tease me," she pleaded.
"I just want to enjoy myself."
Luna did not take her senselessly and instead slid herself into her sister's heavenly warmth a tiny bit at a time. Celestia's cunt rippled around that thick dick as it inched forward rather than rocked back and forth. She screamed as Luna gave her a firm smack on the ass which dropped to a throaty moan as Luna finally bottomed out. Celestia felt her deep inside, not quiet reaching her womb but thick enough to stretch.
Luna began stroking Celestia's cock in earnest, pulling out mercifully faster than she entered. Every thrust was a little faster than the previous as she pounded her sister into the table and her balls smacked against Celestia's full nutsack. Glasses and dishes shook with every thrust against the table. Luna's pregnant belly rubbed against the small of Celestia's back, her hard nipples rubbing against her back and dribbling milk.
"I will be a loving father to your children, just as you will be a loving father to mine, sister."
Celestia felt tears roll down her cheeks from both Luna's words and the sheer ecstasy of her sister's love.
"I want more," Celestia confessed. "Fill me with foals, sister. As many as you can. Even when we both give birth, I want so many more. Breed me again and again and again and don't stop me from feeling you ever!"
Luna was grunting with every thrust and squeeze of her sister's majestic love tunnel, the bell on her hat jingling with every thrust. "Just ask, dear sister, and we'll fill this castle with our kids."
Celestia cried in happiness as Luna yanked her head back and forced a desperate kiss. Celestia could feel Luna throbbing slightly deep within her as she neared her own orgasm. Luna let a free hand move all over Celestia's body in one all-consuming grope. From Celestia's pert breasts, sensual collarbone and full lips, those hips that would expand in just a few months time and flat belly about to be filled with life-giving seed. Luna's cockhead flared to seal the empty womb and Luna broke the dance of their entwined tongues.
"I... I..." Luna couldn't finish her words and bit down on Celestia's collarbone. The mare hissed in pain but that did nothing to stop the all-consuming pleasure and highest of gifts Luna was about to give her. If Celestia's load was large, Luna's load was absolutely massive. The first spurt of cum filled every hidden corner of Celestia's vagina, the second filling her very womb in hot, passionate love. Sheer volume soon distended Celestia's belly as Luna's dick twitched seven, eight, then nine times, the volume not decreasing in the slightest.
Celestia's flabby gut became taunt within seconds and soon visibly bulged with the oncoming tide of stallion semen. She was coming again and screaming her sister's name, spurting another load all over herself and the table. Luna humped her sister every time her cock pulsed and Celestia's hand drifted to her own gut in her sexual haze. She could feel her belly expanding with her sister's love until she herself look pregnant.
Luna collapsed onto her sister's back with a grunt, her cock still lodged within her sister. "Don't pull out," Celestia said and rested her head on the table as she came down from her high. It didn't even matter that she was resting in a puddle of her own marecum and spooge. Celestia picked up a peppermint stick sticky with her own come and suckled the now doubly sweet treat.
"So full..." she said, rubbing her stomach. She looked a good three or four months pregnant. "I feel honored you were saving up so much for this present, Luna. Thank you."
A blue arm reached across her vision and picked up a peppermint stick. Luna swirled it in cum before shoving it in her mouth.
"And in case my present doesn't take, we can always try again."
