Divorce. One word that was never uttered on Equestria before, after all ponies were supposed to find their one true special somepony and never lose it; but now it had happened. After 10 years of marriage the Cakes were splitting up.

"It´s not fair Pinkie!" Pumpkin Pie cried "My mom is leaving the house, to live with another mare! Not that there´s anything wrong with that but...how could she do this? To my dad? To Pound? To me! Even to you Pinkie! Aren´t you mad at her?"

"Well you see honey its a little more complicated than that..."

But there was no use, Pumpkin was too hurt to listen to anything Pinkie said. Defeated she left the store only to be replaced by her brother right away.

"Man I can´t believe my dad will just throw my mum away! For a younger mare! Is he going through a mid-life crisis or something? And I don´t know this mare! Is he ashamed of her or something? Well he should be!"

"Well you see dear its not that simple..."

Just like his sister, Pound didn´t listen and soon leave.

Looking for answers the twins ended up on Golden Oaks, asking for advice for the first friend they ever made Spike the Dragon.

"Mmm that is a problem. Hey why don´t you try this new thing?"

"New thing?" Pumpkin asked.

"Yeah this new law in Equestria...what was it called? Hey Twi, what was that thing we did so we could both marry Rarity? Polygon"

"Polygamy. Its a new law that allows marriages to be composed of more than one individual." Twilight Sparkle explained.

"Oh that thing Rainbow Dash did, right?" Pound said.

"Yes, she couldn´t decide between Fluttershy and Applejack so she decided to instead marry both. It is a...useful solution."

"Yeah, you get to share the be with two mares!AUH!"

Twilight put down the book she magically levitated to slap Spike.

"Think we could do this sis? Talk mom and dad to stay marriage and add their new couples to the family? Like a four-ways-marriage?"

"I don´t know bro but we have to try! We can´t lose our family!"

"You´re right!"

"Come on! Mom wanted me to meet her new marefriend tonight, lets get dad and her date too!"

"Lets!" and the twins ran off.

"...can you do that? Can you have three mares?"

"You´re sleeping on the couch tonight."

****

Pound and Pumpkin looked at their parents and the mare sitting on the middle with a complete blank expression, so shocked by the news they couldn´t even talk.

"You see kids it seems there was a little confusion here." Carrot Cake explained. "We are not breaking the family, we´re actually making it larger by adding another member, one we have always considered one of ours but she had grown to be even more special." and he put an arm around Pinkie Pie.

"She had grown into a beautiful mare and really found a place between us!" Cup Cake said, nuzzling Pinkie.

"Mrs. Cake stop it!"

"Call me Cup Cake darling."

The twins blinked a few times in surprise.

"Pinkie Pie is our new...mum?"

Silence.

"AWESOME!!!! This is so awesome, we have always loved Pinkie she is the bestest of big sisters and now she is also our new mom! Awesomeawesomeawesome!"

The twins danced and jumped all around, filled with happiness.

"...should I tell them I´m also pregnant?"

(author note: oh Pinkie Pie why do I always put you in this crazy situations?)
