Twilight Sparkle was much too... pregnant...

The twin colts she carried weren't just Clydesdales, they were Apples, with a long and illustrious genetic line attesting to their size and strength. She was also a relatively small unicorn, completely dwarfed by her foals' father, and every reason to believe her offspring had taken after him. Worse, by whatever quirk of fate or DNA, her due date had come and passed with little indication that her pregnancy was ending soon. Perhaps there'd just been a mistake when calculating the due date, as no one had expected her to get quite so big, quite so fast, but she was hovering at the end of her 18th day overdue, after an already arduous 11 months. Her belly had ballooned out tightly on both sides of her barrel, the heavy weight swinging low and near the ground when she walked. It limited her options for lying down, as she was doing now, her back tipped slightly down while her swollen stomach and uneven girth took up all of the space in front of her. Even finding a comfortable position was no guarantee of actual comfort, with the way the two Appleseeds rolled and kicked their poor mother's overtaxed womb. Her hooves, her legs, her hips, her shoulders, her back all hurt from being pulled every which way by her oversized stomach. There was a sore tenderness in her engorged teats, growing fat and heavy with the milk her foals would eventually claim.

Yes, Twilight agreed, she was much too pregnant...

Twilight listened as the chatter downstairs in the farmhouse gradually faded, the family retreating off to their separate beds to sleep. She would have joined them, of course, but an afternoon nap had put her too late to eat a proper dinner, and she needed a really good argument to get herself back out of bed that far into the evening. None of the Apple family was brave enough to risk waking an overdue unicorn, either. She eventually heard the sound she'd been waiting for, the heavy clomp of steel horseshoes plodding up the stairs, and the accompanying groans of wood and nails as they shouldered an immense weight.

Big Macintosh let himself into the bedroom quietly as he could. Being a gargantuan workhorse with a bright red coat, he wasn't much for stealth, but he made the effort. He quickly spied that the pregnant unicorn in the bed wasn't asleep, instead giving him a warm and inviting smile. Still careful, but not quite so quietly, he closed the distance, looming over the bedside, and bent to lay his forehead against hers. His red coat met her violet, and he applied gentle pressure, with a care to avoid poking himself on her horn. "How's my little babymamma doin'?" he said, his rich baritone ill-suited for quiet whispering.

Twilight drank in Mac's heady musk. Fresh air, dirt, straw, spices, and the ever-present hint of apple combined with raw masculine strength and grit. It was enough to get just about any mare's heart racing, and had likely been instrumental in Twilight's current pregnant predicament. They shared a kiss as they slid each other's nose across the other's, lingering and parting slowly. Mac then leaned further over the bedside to the curve of Twilight's form, sneaking his muzzle in amid the blankets to rub his cheek against her velvety coat.

"Surviving,' she finally replied with a tired, but contented sigh. It had become something of a game to say as few words as possible between, and instead let the meaning flow through context and action.

"And my boys?" he asked, reaching out a hoof to gently press against her bump.

"Stubborn..." Twilight answered, the word just as pregnant with meaning as she was.

Mac chuckled, gently patting her stomach. "Eyup. Like their daddy. Or their great-granny."

Twilight shifted her weight, exposing more of her stomach to Big Mac, still sighing wistfully, "Oh, well, what can you do?"

Mac took the opportunity to drag his hoof along his lover's middle, feeling the swollen tightness of the skin. He rubbed her stomach for long seconds before replying, a hint of mirth still in his voice, "Could always see if I can get things moving..."

Mac was rarely subtle with his come-ons in private, and as usual, his intent was evident enough. Twilight shared the glee in his suggestion, laughing quietly, "That hasn't worked the last... twenty six times you've tried?"

Of course, Twilight had kept a count of every time since her due date that Mac had attempted to get her labor started with a good, deep bucking. They were memorable enough occasions, even for a pony who didn't fastidiously mentally record such things. And obviously, none had worked.

Mac's hoof continued its stiff exploration of Twilight's overdue proportions. The stallion kissed her bump and brought his head back to give her another, longer kiss on the mouth, before rumbling with his hot breath, "Supposin' I wasn't really tryin?"

He caught her in a second kiss before she could reply, whatever words she'd had stuck in her throat. He kept the initiative as they parted, adding, "Supposin' I didn't want ya to pop?"

He seized her in another, more forceful lip lock, though she'd had no reply ready, only a keening squeak. In predictable pattern, he relented and continued, "Supposin' I like seeing you so pregnant?"

Twilight already knew that Mac greatly admired her gravid body. He was singularly incapable of that kind of deception. But the declarations were just the thing the overdue unicorn wanted to hear, her pulse quickening and her loins growing hot and needful. Not that she even required much prompting with the near mythically constructed stallion making the advances.

Mac's titanic hoof had paused and was pressing against Twilight's taut belly, and her foals shifted and moved in response to their father's touch. It caused another small squeak of surprise in the back of her throat, and a relieved, satisfied sigh as she collected herself. Her colts continued to kick, another sensation further heightening her mood. Finally given a spare moment to form a thought, her vocabulary was given over to one questioning word, "...eyup?"

Mac answered first with another kiss, beginning to pull Twilight closer to him. The workhorse was still standing over the side of the bed, tall enough that he didn't even need to get up on his haunches to reach across and envelop Twilight in an embrace, and strong enough that the pregnant mare was no strain on his muscles. He tried to quiet his voice, but only managed to deepen his bass, as he drawled, "You're more beautiful now than you've ever been. An' I ain't exactly eager to see it end..."

Twilight's anticipation was reaching the level of screaming "TAKE ME NOW!", but Mac had a way of keeping one step ahead of her and, somehow, ramping up the tension. He lightened his grip and let the unicorn down onto the bed once again, now on her back, with her hindlegs dangling over the edge, and her overdue stomach sticking up and out below the stallion's intense gaze. "'Had no idea such a little pony'd be strong enough to carry TWO of my boys. Had no idea she'd make it to the end. Had no idea she'd still be carrying these big ole' foals well after that," he declared, putting his front legs on the bed to rub at Twilight's stomach from both sides.

Mac paused in his monologue to lick Twilight's lower stomach with his tongue, intentionally careful to graze her teats as he began, ending near the apex of where her belly button jutted out. "But always so chipper. Always so vibrant. Yer hair, yer coat, yer eyes, and yer big, pregnant belly, still gettin' bigger..." his drawl thickened as his words outpaced his brain. "Knowin' that yer MINE. That I did this to ya. That those're MY foals. And ery' day longer it lasts is proof o' jus' how strong ya are." He shook his head, hint of a smile creeping across his mouth, "Nope. Don't wanna see it end. I wanna see how much stronger ya are..."

Mac finally began to utilize his lower half, his massive stallionhood beginning to probe at Twilight's lustful mound, and the workhorse's height meant he still loomed over Twilight and the entirety of her oversized belly. He said, slowly and distinctly through his grinning teeth, "So I am gonna take what's mine, and I am going buck you good and deep. But I ain't going to pop you. You're going to stay good and pregnant. You're going to keep carryin' my foals. And you're going to love every minute, for a long as you can..."

Mac began to apply press-

There was a knock at the library door, and it opened shortly after, accompanied by a flurry of footsteps. Twilight Sparkle was torn from her fantasy and frantically tried to hide what she'd been doing. She had relative privacy in the upper eaves of the library, but the only being so brazen to enter after knocking, not to mention with actual feet to make footsteps, was quite at home in the dwelling they shared.

"Hey Twilight? You seen my source book? I thought it was with the monster manual, but I didn't see it when I got there..." Spike the Dragon questioned, scurrying along the lower floors to check the tables, chairs, and shelves for his lost item.

Twilight called down, tamping her frustration, "Should be on the shelf next to the door. Bottom left." She banished the big red... toy to her pocket dimension of unspeakable secrets. She hunkered down in her bed, wrapping the blankets around herself, hopeful to appear as if she'd just been reading in bed. Hardly a bad disguise for the bookish pony.

She heard Spike return to the door, and yell, "Oh, dude. How did I miss that? Thanks Twilight!"

The door open and slammed shut. Twilight flicked the lock closed with telekinesis, grumbling at her failure to do so earlier. Alone again, she sighed and pulled back her blankets. While her Big Macintosh had been just a conveniently colored toy, her belly did appear every bit as pregnant as in her salacious fantasy.

A unicorn of particular desire and near unlimited magical aptitude had a few extra tools at her disposal when it came to scratching an itch. A complicated matrix of shapeshifting, illusion, and nature magic spells combined to give her a pregnant stomach almost indistinguishable from reality, even if she took a few liberties on the size. It would even move, or seem to, on its own, owing less to the contents than to a table of magical variables and random chances. The spell even tweaked her hormones to give her a more authentic experience. The only real missing piece was that it did not change her actual dietary requirements. A rather involved setup ritual was the only reason she didn't dispel it immediately upon Spike's intrusion.

It was an invaluable enchantment to a horny unicorn whose biggest kink, by far, was pregnancy. Even better for a socially maladjusted bookworm with severe anxiety and a LOT of steam to blow off. Twilight had used it to fuel a plethora of erotic fantasies, where she was invariably bred and left to grow heavily pregnant. Experiencing pregnancy for herself was an intensely satisfying turn on, though her own pregnancy was hardly the limit of her fascination.

She was blessed, or cursed, with a large swath of attractions, and she'd just as eagerly enjoy the pregnancy of another mare. What made things difficult was her group of friends had some of the most stunning mares in Equestria in it. And while she hadn't had the courage to invite any of them to try her special spell, they did figure heavily into her fantasies all the same.

Pulled abruptly from her earlier scenario, Twilight needed some time to settle herself back into the proper mood and mindset. She lay back and rubbed her oversized stomach, letting herself forget that it was just an illusion...

Again, just something I needed to get out of my head. Now, off to horny jail.
