When Rarity tries running a race dressed in a sports outfit of her own design, she drinks a lot of water. It then comes time to teach at the School of Friendship, and she does so in her outfit, which the sweat has dried off already. However, she soon becomes distracted, as she has to pee really badly from drinking so much water after the race. She tries to avoid telling her entire class she has to use the little filly's room, but soon she's in desperate need of a bathroom so she quickly excuses herself and races towards the nearest bathroom, but she doesn't make it.

So she sheepishly walks back into class and continues teaching in her wet shorts. Her students stifle some laughter, and Rarity giggles nervously as if to laugh with them before class resumes as though nothing happened. When class is over, Rarity discovers that she likes the feeling of wetting herself, and takes great pleasure in the state she is in.

Of my pony pee edits I noticed the ones of them after the wetting rather during the wetting are more popular, something about the way the puddles were drawn I guess, so that's what I went for here with Rarity. Giving her my usual sporty outfit, colored like EqG Rarity's usual outfits.
