Feeding the Sun

>You shush the temperamental mare as you rock her in your arms.
"I understand that you're a little bit embarrassed by being fed like a little filly in front of your sister, but lets not forget that you lost our little bet from last night."
>She looks away with frown as you reposition the large mare in your arms.
"Is my big girl upset because she hasn't had her cake yet?"
>Luna snickers as she wipes her mouth with a napkin and enjoys the show.
>"ANONYMOUS!" Celestia shouts in the royal tone. "THIS HAS GONE ON LONG ENOUGH!"
"Aw, poor baby you're right this has gone on long enough!"
>You smile as you cut a small piece of cake and wave it around her muzzle while making airplane noises.
"You'll need to open wide so the airplane can come in for a landing Celly!"
>The defeated mare's ears drooped down as she opened her mouth and waited patiently for the piece of cake.
>After she closed her mouth around the fork you removed it from her mouth, smiling as she began to chew the confectionery treat.
>"Never again Anon." She mumbled with a mouthful of cake. "Never again."
>You lick off a bit frosting from her muzzle and give her a quick kiss.
"That's what you said last time Celly."
>The mare blushes and gasps as you position her over your shoulder.
"Time to burp the baby!"
>Luna fell to the floor, rolling around guffawing like a donkey.
