Inexperience is a foreign concept to Celestia. At least she thinks it is. Right up until the moment a rash decision leaves her with a student who is a dozen years younger than what she's used to.
Enjoy.
I'm a simple guy... I love Sci-Twi x Sunset/SugarCoat, and Pony Twilight x Celestia/Chrysalis/MoonDancer/Trixie. Also, I love Fighting Games, Dark Souls series and Yuri in general.
