I had been a year after our wedding when we decided to have foals. It turned out magic ponies have a lot shorter pregnancy than their earth counterparts. We had a lot of fun while I tried to get Luna pregnant, thanks to the spell she had told me about. After only two weeks we had success and Celestia was happy to hear she would be an aunt soon. Thanks to the very precise time of a changelings pregnancy to the hatching of the eggs, and Chryssi's ability to get pregnant whenever she wanted, we were able to time their pregnancies, so the foals would 'hatch' at about the same time. It was only a week of shared pregnancy before Chrysalis would push out the egg, but they had a lot of fun commanding me in this week to do whatever they needed.
...
We were all in the same room, Luna laid on a bed ready for the birth of our foal, while Chrysalis guarded a pulsing egg from which our şahzadə would hatch. Luna was first and we both held her hooves and wiped her sweat until our little filly 'Aurora' was born, I laid her on Luna's belly. Her fur was a much lighter blue than Luna's and her mane had a dark orange like the sky at dawn.
"Does the name for a child influence its appearance?", I asked confused.
"I decided she would be pretty this way, so I have influenced her with my magic, isn't she pretty?", Luna asked.
"She is wonderful.", Chryssi and I said in unison.
...
It was only one hour later when the egg started to move, and we knew our second foal was about to hatch.
"Shouldn´t we help it?", I asked.
"No.", Chrysalis said in a soft voice. "She can make it without a problem, trust me."
It took several more minutes but finally she broke out of the shell.
"Hello little Cara.", Chryssi said and carefully cleaned her from the remains of the egg... it was a bit strange to see she used her long tongue for it.
"She is adorable.", Luna whispered because Aurora was sleeping in her embrace. Cara was black of course, but her mane and tail had a blue color.
"She sure is.", I said. "I am so happy to have these beautiful foals."
I kissed both mares. "Thank you both for giving me the best times of my life."
