The sun was out casting light across Equestria. Two alicorn princesses were in the castle relaxing.
"Twilight how did this happen?"
"Well we were in your bed chambers one night..."
"Not that! I mean how did we go from teacher and student to two ponies in a committed relationship?"
"I think that we have always had feelings for each other, but they blossomed just recently."
Twilight laid on the chair by the pool, sunglasses over her eyes and loving the relaxation from her normal duties.
"I'm a little hungry. Are you hungry Celestia?"
"A little. Do you want to have the chef cook us up something?"
"I'd love that."
Celestia's horn lights up and grabs a pen and paper. She starts to speak and write the note asking for some food. Once she is done writing it she sends it to the chef.
"Here you are your highnesses."
The two princesses take the food and start eating.
"This food is so good."
Twilight feels a small kick in her womb.
"I think the foal would agree haha."
"That is good. I cannot wait until that foal is born."
"Neither can I Celestia. That day will be a new milestone for us."
They continued to lay there and soak in the sun. It was a beautiful day after all. Twilight thought of a funny prank to pull on her lover. She got up and silently walked over and using her magic she lifted Celestia up and tossed her in the pool then jumped in after her. Celestia rose up and inhaled air and Twilight followed suit shortly after and started to laugh a bit.
"Oh you think that was funny huh?"
"Yes that was the point besides it would allow us to do something fun."
"Oh I see well I think that this will be funnier."
Celestia teleports both Twilight and herself inside her bed chambers and starts to tickle Twilight. Twilight laughs from the tickling assault, but Celestia doesn't let up.
"S-stop it! haha haha."
"Hmm no. You shall suffer your punishment for getting me wet."
Celestia keeps on tickling Twilight and Twilight kept on laughing.
"S-seriously stop it."
"Why honey? Can't handle me tickling you?"
"I might pee all over your bed if you do not cease!"
Twilight blushed after her statement and Celestia stopped tickling Twilight. She got up and ran to the restroom and started to do her business. After a couple of minutes she came back out still blushing and not looking at Celestia.
"Twilight I'm so sorry. I did not mean to almost make you pee."
"I should be the one to apologize to you. I did not mean to toss you into the pool."
Twilight walked over the bed slowly and sat down looking at the floor embarrassed. Celestia Grabbed Twilight's head and lifted it up and turned it towards her and gently kissed her.
"It is alright Twilight. There is no need to look down and be sad or disappointed."
9 Months Later
It has been nine months since Twilight took that pregnancy test and now her gut is huge and she is miserable.
"Please let the foal come already! I want this to be over with!"
"Just a couple of more days Twilight then the foal will be born and we will be happy."
Twilight and Celestia laid there thinking of all the happy memories that would happen after the foal would be born. As they thought about the memories, they were smiling and grinning. The foal kicked Twilight's womb and it caused her to have a contraction. Twilight started to have more and more contractions and each one happened at different times. At first they were twenty minutes apart then they started to get faster and happened at ten minutes apart.
"The contractions are happening faster! I don't know if it's cramps or if I'm about to give birth! Call the hospital!"
Celestia grabbed the phone and dialed the hospital frantically explaining what is happening.
"Yes?"
"Hello, I have someone here about to give birth! Can you send an ambulance?"
"Right away ma'am. Where is your location?"
Twilight's water breaks and she moans loudly in pain.
"Canterlot Castle! Hurry!"
Celestia hangs up the phone and goes back over to Twilight's side.
"The ambulance is on its way here. Just hold on a little bit longer honey."
Twilight moans in pain and Celestia grabs her hoof and holds it tight. The ambulance arrives and they get Twilight onto a stretcher and take her to the hospital, Celestia never leaving her side. The doctor comes in and runs some tests on her to see what is going on.
"Well it looks like she will be giving birth in a matter of minutes."
Twilight groans from another contraction and Celestia holds her hoof tighter.
"Just a few more minutes Twilight then our foal will be here. Isn't that wonderful?"
"Yeah that sounds wonderful Celestia, but I am in a lot of pain at the moment."
"Just hold on a little longer honey."
The contractions stop for a little bit giving Twilight a break. Celestia goes and sits down by the side of her lover. After a short time Twilight starts to moan in pain again. The doctor comes in and examines Twilight.
"Push Twilight! You have to push!"
Twilight groans and pushes, but the pain doesn't seem to stop.
"You have this honey just breathe and push."
Twilight breathes for a couple of seconds and pushes some more.
"Yes! That's it! Almost there!"
Twilight pushed as hard as she could and the doctor grabbed the foal.
"Congratulations! It's a boy!"
"Twilight we have a baby colt!"
"Yes now can you cut his umbilical cord so the doctor can clean him up?"
Celestia grabbed the scissors and snipped the umbilical cord then the doctor took the baby and cleaned him up.
"Here you are Princess your baby boy."
Twilight grabbed him and looked at him smiling.
"He looks just like his mother."
Celestia started to tear up and hugged her new family.
