Hypothesis: Foals

Twilight thought she knew how to clean, she felt like she’d done nothing but that since this whole tale started. But nothing could’ve prepared her for cleaning up child birth. It seemed like all the bags, wipes, and towels in the world couldn’t remove the sheer waste she’d made in the past hour.

But anytime she felt her annoyance rise, all she had to do was look at the now sleeping foals sitting in their own cots. She’d done all the hard work, now she’d get to reap all the rewards.

Dropping the towel into the dark bag, she walked over to the fillies cot. She looked the most like her father, a vibrantly red mane with pale blue fur barely growing in. Not just that, she had the tiniest wings sporting from her sides just like Rainbow indeed. She was the definition of innocence as she slept, her tiny head moving up and down softly with her breath.

Twilight smiled and flared up her magic, slowly flipping the filly onto her back. She traced her eyes down the newborn’s body, sizing her up and admiring her creation. At the end of her tiny body, was a similarly small vagina looking barely big enough to fit a toothpick inside.

Twilight traced her magical grasp around the foal hole, pressing what felt like a needle inside to spear the foal open. “Not even a day old, and you’re already spread open. What a little slut you are~” She dirty talked, though it was mostly to herself.

The filly didn’t even stir as she was penetrated by her own mother, the only sign of discomfort being a small hitch in the sleeping breath. She’d grow up to be a real star, Twilight was sure of it.

Looking over at her twin brother, she felt a similar rise in her chest. He was just as tiny as his sister, just without the wings to go with it. Just a dark blue coat, and a dark blue mane.

With a quick flick of magic his sleeping form was upturned the same way, his legs instinctually spread. Unlike his sister, all that was at the base of his crotch was a tiny sheath with the smallest scrotum. “Aww, what a cute little stud you are.” Her magic fondled the skin tight package, “You better grow up nice and big for mommy~”

And grow up was right, they were way too young to do anything too adventurous with yet. Good for eye candy, but if she really wanted to enjoy them she’d need to train them. And that’d never happen with them now.

Still, that didn’t stop her from imagining.

Looking back over at the pair, she pictured them in the heat of passion. One over the other, without a condom in sight. The innocent incestuous pair breeding like rabbits, as it’s the only thing they’d ever known. One knocking the other up, starting the whole cycle all over again.

Twilight was already panting thinking about it, her hoof having shifted to teasing herself without even consciously registering it. All the months of pain and work, all the lies she had to tell. All for the two foals she now had complete control over. Incestuous foal sex, whenever she wanted it.

The filly cracked open an eye, clearly curious as to what her mother was doing. This only added fuel to Twilight’s fire, her hoof moving even faster as the tiny foal stared with beady eyes.

“Yeess~ Watch your kinky mommy cum in front of your foal faces, get your innocence tainted before you’ve even seen the world” She rambled, half gone with ecstasy

It wasn’t long before Twilight crested her own edge, her first orgasm of many in front of her precious foals. A special moment to be remembered for sure, one they would only hear the story of. Twilight looked down at the cots, both of the foals were deep in their own sleep.

Which reminded her of her own tiredness.

It’d been a long day, and frankly she couldn’t care about going back to her proper room. Twilight climbed into the bed she had used for something entirely different not too long ago. Soon sleep began taking her too, a satisfied smile on her face.

There was plenty to do tomorrow, that was for sure.
