Shining Armor has always hated his birthday since he was a colt. It always brought back bad memories from his foalhood. Always having to be the man of the house while his father was away at work. He doesn't like this day, and doesn't want to do anything to celebrate this year.

But when his sister Twilight Sparkle wants to throw him a birthday party, he can't say no.

Underneath all of this is a secret he's been keeping, and with a stressful day like his birthday coming up, he isn't sure he'll be able to keep it much longer.

Warning: Contains ABDL/ Age Play themes and content. It's a sequel to a previous ABDL work, so if it's not your cup of tea, don't read it. I added the fetish tag even though this is a nonsexual ageplay fic.
