Rainbow's Punishment (private with Princess Cadence)
 

Rainbow lay on a the branch of a tree, snoring quite loudly. She had just finished a few tricks and nearly flew into a tree, so she decided to take a nap.

Applejack watched the Pegasus perform her trick. She was impressed but shook her head when Rainbow crashed. Thankfully the mare had a stubborn head and body so that did not hurt her much. What Applejack was most expecting was Rainbow sleeping in a tree snoring. That was the sight that was right in front of her. She couldn't believe how childish Rainbow Dash was. She could've ended up in the hospital for more than a year if she didn't land the trick right.

Rainbow continued to snore as Aj looked on. Her hoof came up to her mouth, and she began to suckle it just like a foal.

(Use a tiny bit more detail and don't rush into it and can this be the human with wings sorta RP)

Applejack could not believe what she was seeing.

(Sorry. I'm kinda new to rp. And sure, we can do that.)

Rainbow continued to suck her thumb as she slept. She was currently dreaming of flying with the Wonderbolts, which was what she normally dreamed about.

(Its fine and thank you)

Applejack looked at the mare with wonder. Here was one of the "tougher" mares in Ponyville and yet she was sucking her thumb. With no struggled Applejack was in the tree and she slowly started to shake Rainbow Dash awake. "Hey Sugarcube you're gonna get caught doing that if you aren't careful"

Rainbow groggily awoke from her slumber. "Wh-wha'?" She mumbled, not even noticing that her thumb was still in her mouth.

"You're sucking your thumb hunny" Applejack gently pulled the thumb from the mare's mouth.

"Aj!" Rainbow sat upright and ended up slamming her head into a branch above her. "Ow." She rubbed her head. "You...you didn't see that."

"I did see it sugarcube" Applejack giggled.
