”HE DID WHAT TO OUR FLURRY UNDER YOUR WATCH?!” Shining Armor yelled, glaring at Pinkie, virtually fuming. While the twins and Flurry slept, Shining and his wife Cadence had been called from their anniversary party by Pinkie, the messenger telling them it was an emergency. They’d arrived...and been told that Pound, Flurry and Pumpkin had had sex, with both young mares smelling of estrus and him being virile.

“I...um...kinda fell asleep and...when I woke to them whinnying and yelling I went to check on them and...” Pinkie mumbled, before clamming up again, still looking rather pale as she wilted under the glares of four angry parents.

“...and our Pumpkin and Pound...twins doing that together? Is that even...would foals from it be...OK?” Mrs. Cake asked, looking to her husband, then Shining Armor and Cadence, “Is it even legal?”

“Well, they’re just foals being foals, everything unintentional, but let’s just hope nothing comes of this. Incest is also not illegal. First generation incest among ponies isn’t as critical of a problem as with some species given our redundant chromosomes, therefore making bad traits less likely to pass on to foals born of it. So, it shouldn’t be too much of a problem even if Pumpkin does get...well...” Cadence said, seeing the scared expression on Mrs. Cake’s face, before changing the subject; “Well, we’ll obviously have to tell the foals about the ‘birds and the bees’ and safe sex when they wake up though, and why they can’t do this without protection...especially not with Flurry being an Alicorn.” Cadence said, a look of worry on her face.

“Oh, and why’s that?” Mr. Cake asked, cocking his head slightly, “What’s so different about alicorns having sex?”

“Well...” Cadence said, looking to him with a gloomy expression, “Alicorns are induced ovulators.” she said, but, with the confused looks she got, she continued; “Alicorns, given our rarity, have developed different...reproductive strategies than other races of ponies. Namely, we don’t have heat cycles. We’re always fertile, at virtually any age, on any day, and will be induced into estrus upon having sex and being inseminated regardless of the season, and the more we have sex the more likely we are to ovulate. Shiny and I found that out the hard way...that’s where Flurry came from. Me being constantly fertile wasn't something Celestia told me about upon my ascension to being an Alicorn, so we simply thought I was infertile given I didn’t go into heat like other mares. We didn’t use protection during my and Shining’s first time on our honeymoon and...well, let’s just say it bore fruit.”

“...and that other smell...that was probably Pumpkin’s heat...” Pinkie said, looking grim.

As she said that, Mr. and Mrs. Cake looked as pale as Pinkie did, and Cadence nodded.

“Yep... we all just might be grandparents soon.”

After several months, and a seemly overdue sex-ed talk between the parents and their foals, Carrot and Cup Cake learned that Pumpkin was in her first estrus when she and Pound had sex and indeed, unintentionally, had gotten pregnant by her brother. After some discussion as a family, and heavy insistence by Pound and Pumpkin, they decided to allow her to keep the foal. Her pediatrician said that Pumpkin would be able to safely carry a foal to term at her age.

Pound and Pumpkin were, however, told that they're never allowed to have sex again, much to their disappointment. After mentioning this later to Cadence, and with her being the Princess of Love and valuing love in all its form, she persuaded the Cakes to modify it so that they can't have sex without protection, and their parents reluctantly agree. They also mention that Flurry may also have sex with Pound and Pumpkin under the same conditions, until she is old enough to consciously decide she’s ready to have children, or more children, if she turned out to be carrying.

Flurry also became pregnant by Pound, to Shining and Cadence’s expectation. The two were initially worried about Flurry being too young to carry a foal, but were assured by Celestia that Flurry’s body will magically accommodate the growing foal safely, so they agreed to let her go full term.

Pound obviously was in big trouble, but neither set of parents really blamed him for getting both of their fillies pregnant, as it was through all four of their own actions and negligence of privacy that their children learned how to have sex so young, as well as it being completely accidental. Pinkie, on the other hoof, was not allowed to foalsit for them alone again.

Soon after, the twins also learned that their mother had indeed gotten pregnant herself through the act that had allowed Pound to learn about sex, carrying her own foal alongside her daughter, both pregnant together.

At just over eleven months of carrying, Pumpkin, Flurry, and Cup Cake all safely delivered their foals within days of each other. Pumpkin gave birth to a cream-and-coffee-colored pegasus colt whom she appropriately named Coffee Cake, his coat a soft creamy brown and his mane a dark orange. Cup Cake delivered another set of twins; a bright green unicorn colt with a pale-orange mane whom she named Lime Cake, and a butter-yellow earth pony filly with a white mane whom she appropriately named Butter Cake. Finally, and to the greatest fanfare, Flurry Heart gave birth to an Alicorn filly, her having a pale-orchid-pink coat with a two-toned-blue mane much like her maternal grandfather’s, whom they named Froststorm; Equestria’s newest princess.

The trio soon grew closer than friends, bonded through raising their healthy foals together, and in their later adolescence Flurry asked Pound and Pumpkin to join her royal herd, to which they all too happily agreed. They and their foals grew together, their love for each other alongside, all three remembering that all of this happiness came from simply trying something new and, of course, a number of very good poundings.
