On the Study and Application of Advanced Carnal Magic

The last time Twilight had to hold someone’s hair while they leaned over a toilet was the night after Rarity was banned from every single bar in Ponyville, an event the local bartenders call “The Time of Knives.” Starlight slowed her puking to some dry heaving before wiping her mouth across her fetlock. Twilight released her magic and let Starlight’s mane fall across her sweaty and ashen face.

“I think the term “morning sickness” is a little bit of a misnomer after lunch,” Starlight said between tired grumbles.

Twilight let her eyes drift over the gentle swell of Starlight’s expanding stomach. Starlight was perhaps even less physically active than her and the biochemical changes that came with foals made motherhood a little rougher for her than she calculated. Trixie, on the other hoof... she was another story.

But as father always said, motherly tones were the best magic. She gave Starlight a gentle nuzzle that brought back her favorite smile. “I can brew something to settle your stomach. Come now, I don’t want to catch you asleep on the bathroom floor again.”

She gave another affectionate prod before nudging Starlight out of the bathroom. Fussing slightly under her breath, Starlight led the way into the castle common room. At least hoof pain wasn’t yet a problem in the castle. Yet.

Twilight sighed and ran a foreleg along her own belly bulge. Two heartbeats.

“We’re going to be mothers...” It still felt too unbelievable to be real. Now that her life had settled down somewhat, foals and marriage were on the table, but never in her wildest dreams had she anticipated things turning out like this. Feeling her own belly filled her with such giddiness and warmth every time.

Twilight trundled into the common room after Starlight only to discover both her and Trixie on the couch snacking on a bag of pretzels.

“It’s really not healthy to binge on salts and junk foods, Trixie, and Starlight, you...”

Trixie’s exaggerated mom shuffle off the couch stole the air from her lungs. Of the three of them, Trixie had taken to her pregnancy like a duck to water. Whenever Twilight saw her lounging around the castle, it was often in a provocative pose specifically designed to make her blush as the mare maternally stroked her ballooning abdomen.

Trixie sashayed until she was nose to nose with her. The weight of three month old foals and Trixie's smokey and lustful look made her sit back on her haunches.

And then she stuffed a hoof full of pretzels into her mouth

“The princess doth protest too much,” Trixie purred before turning on her hooves, her tail brushing underneath Twilight’s nose.

Something flicked her forehead and Twilight snapped up. “Fwat fas vhat for?” she whined to Starlight. Mmmm... pretzels. She really was craving salt.

“You were almost drooling.”

“I don’t mind.” Trixie settled herself on her side as she lounged on the couch, showing off her belly. Stupid sexy Trixie.

But Twilight admired that Trixie knew full well the effect she had on her and exploited it to keep her calm and relaxed. Knowledgeable she may be about the general biological changes and processes of pregnancy, she still had a known tendency to overreact. Trixie was the glue that kept the three of them together while Starlight was unofficial den mother.

“Before I forget, Nurse Redheart finally got back to me. Doctor Stable had finished testing all of our bloodwork and analyzed the sonograms. We’re all carrying twins.”

Trixie just shrugged and shoveled more garbage into her mouth, but Starlight picked up what was unusual about that immediately. “How rare are twins, anyway? I know single births are by far the most common, and twins do happen, but three sets of twins at the same time? How rare is that?”

“Very.” Twilight’s horn flashed and started filing away yesterday’s work she had let out in the common room. “So much so that there is no record in Ponyville of it happening thrice. That’s why I asked for bloodwork done, just in case. What came back was... interesting to say the least.”

Twilight sat down. The added weight wasn’t a problem, despite the feeling of expanding like a balloon. Her breasts swelling and rubbing against her legs with every step? That was going to get real annoying, real fast.

“Do you know what false twins are?”

Trixie just shrugged again. Starlight shook her head and said, “Can’t say I have.”

“It’s exceedingly rare in of itself, but even more so now because it happened to all three of us. False twins occur when a set of eggs have been fertilized by two separate fathers.”

If a mare with a set of magically-conjured junk could be called a father, and two of them at that. A moment of silence drifted between the trio as what happened settled in. It was very apparent that they had impregnated each other after a month had passed and the changes that came with all pregnant mares had settled in. But this? Twilight carried both Starlight’s and Trixie’s child. Her student and her endlessly irritating and stupidly pretty rival fucked her senseless and impregnated her.

“I think you’ll make a good mom, Twilight.” She blinked. There was no hint of mockery in Trixie’s voice.

“It’s not about ability. I’m a princess, I have a stable social network, I have resources to exploit—”

“You’re unbearably nice. While that serves Trixie well enough when she wants to pull your mane a little when you’re moaning, you go out of your way to help other ponies.”

That was probably the highest praise Twilight had ever heard from the mare, all things considered. “Thank you for the vote of confidence.”

“Think of it this way: do you regret what happened?”

The most intimate and emotionally mollifying day of her entire life? Not a chance. The consequences of that night however, were going to have consequences reaching decades. What was Celestia going to say when she finally mustered up the courage to tell her not only was she pregnant from two different mares, but she impregnated those very same mares herself? Already she was having children out of wedlock.

But the prospect of motherhood did have a certain appeal, even though that may have been the hormones talking. She had saved the world a few times, even gone so far as guide the town through various calamities. She had helped teach a student of her own and felt a distinct responsibility for Starlight, and now even more so considering Starlight carried her child. There was a certain maternal joy only an expecting mother could understand. Her friends were her friends and their bond was tighter than anything, but there was a sort of fragile and still pleasing kinship with these two mares that shared her bed and heart. Their bellies swelled and they spent the occasional night in each other’s bed, sometimes as a precursor to lovemaking, other times just to bask in the motherly glow of each other. Fecundity had blessed them, and that blessing was scary.

Children? It would be an awfully great adventure.

“Not in the slightest.”

“Good! For a second, Trixie thought you were going to go all crazy eyed on her.”

“I do not go crazy eyed!”

“Well, your eyebrow was twitching a little,” Starlight added quietly.

She was not even close to a Lesson Zero level event. Not even a Rarity at the bar level event. She turned away and cantered towards the door. She did have a lot of work to do, pregnant or not. “It’s just a twitch from lack of magical exercise. I haven’t been exerting myself nearly as much.”

“Trixie smells your bullshit. Anyway, Trixie’s conjuring has improved. Teacup!” Twilight heard the flash of magic and a clink.

“I’ve got some paperwork to file at the town hall later, but I can work with you afterwards if you want some guidance, Trixie”

“Acceptable, but how does it look so far?”

Twilight turned around. Trixie’s teacup was a flowery pink and rose-colored piece of porcelain with a half-heart-shaped handle. Most impressive for a mare with so little experience in conjuration and transfiguration. What drew Twilight’s eye more than anything was the eight or so inch slab of meat now laying across her thigh, drooling precum.
