Sexy Nightmare

Later on...

Twilight and Spike landed in front of the door of Rarity and Sweetie Belle's home. Twilight knocked on the door three times with her left hoof. Then, Rarity opened the door and greeted her friends. "Twilight, Spike, to what do I owe the pleasure of my two friends visiting my home?" Rarity asked.

Meanwhile, in the dress-making room...

"Oh dear, are you SURE about this, Twilight? I mean, this is Nightmare Moon we're talking about," Rarity started.

"Yes," Twilight replied.

"And Luna said that her.. "other self" wants to be in somepony else's body and Nightmare Moon chose.. "YOU?" Rarity finished while pointing her right hoof at Twilight. Spike was standing on Twilight's left side.

"Mmhmm," Twilight answered with another nod. "Well, maybe it's just because she's bored and getting tired from seeing the same pony. I'll ask Luna later on," Twilight reassured Rarity.

"Well, as one of my best friends, I respect your decision," Rarity started. "Now, go on over to the spa and get prepared while also looking amazing while I make the clothes you need for tonight," Rarity finished. After a group hug with the two ponies and dragon, Twilight and Spike head out by walking out of their friend's house and over to the spa. Spike walks on Twilight's left side as they journeyed to the spa. After they left, Rarity quickly ran back into her dress-making room as a speed of light and started making the attire Twilight needs for tonight.
