Original Description:

Fluttershy slowly walked across the lawn behind her cottage in my Anthro MLP dreamscape. It was early in the morning and it was shaping up to be a very bright and toasty day. The pegasus mare came to a stop in front of the small group of ponies who were waiting for her. With the golden light of Celestia orb behind her the mare addressed her students.
“Um, good morning class. I want to thank you all for, uh, being on time for the first day of class. Following instructions and promptness will be, um, important foundational elements of this, uh, curriculum.”
The chiffon yellow mare slowly started pacing back and forth in front her students. Her Cercis pink mane and tail swayed and bobbed in time with her steps, along with other parts of her that were supported by the leaf green bikini top. Matching bikini bottoms peeked out from under baggy denim jeans. Hanging from her right hip via a black leather belt was her signature coiled 12ft black bullwhip. As Fluttershy paced about she kept speaking.
“Now, um. Today is strictly an orientation session. Where you’ll learn what to expect and, uh, what to look forward to in, um, upcoming lessons.”
She took a moment and glanced at her outfit. “That’s why today is um, an informal, and uh, more casual thing, and besides it’s going to be very hot today. So let’s go and sit down under that big old oak tree and we’ll get thing started. Okay?”
Then she slowly started walking toward the shade of the tree with her class in tow.
Recently there’s been a meme of drawing a female character in bikini top and baggy pants. Well my subconscious picked up on it, and I had this dream last night. Thus the drawing.
