A Rare Opportunity

Rarity panicked. "Why is Sweetie Belle here?!" she thought to herself. As the filly started to awake Rarity was in full panic mode, so without thinking she grabbed a newly designed dress that was gently set on a nearby chair and without hesitation, sloppily put it on. The filly was sitting up now, rubbing her eyes.

Sweetie Belle repeated herself: "Um, Rarity, what are you doing?" she said half-awake.

"Oh I'm just...seeing if this new dress fits me! Yeah, that's what I'm doing!" Rarity said trying not to look embarrassed. "Sweetie, I'm not trying to sound rude or anything, but why are you here?" She added.

"Well you see, Scootaloo, Applebloom, and I were helping Pinkie set up decorations for Raindrops' birthday party, and she asked us if we want to stay for the party. Of course we said 'yes' because we had nothing better to do, so we stayed and it got pretty late" A now fully-awake Sweetie Belle said. "So I used the key under the mat and slept here!"

"Oh, well then" Rarity added trying not to clench her nose at the smell coming from her rear. She was at a loss of words at the moment and completley changed the subject. "So, how about some breakfast Sweetie?" She said nervously.

"Breakfast sounds great, I'm starving!" Sweetie said. She stuck her nose up "I can smell the bacon alr....." Her words instantly came to a halt and she covered up her nose. "EW! That doesn't smell like bacon! It smells like one of the cake twins' need a diaper change" The little white filly said.

Beads of sweat started to run down Rarity's face. "I..um don't know what you are on about Sweetie." She said nervously. Sweetie glanced at Rarity suspiciously.

"Riiiiight." She said. "anyway...let's get out of this room and go get some breakfast. This room smells funny." She said with a small devious smile. She headed for the door and tried to open it to find it locked. "Rarity why won't this stupid door open?" Sweetie said as she hesitated with it.

"Oh, it's locked, Sweetie." The white unicorn replied.

"Oh, okay!" Sweetie unlatched the lock and opened the door. "Why was it locked anyway?" she said curiously.

"Oh..um" Rarity searched her mind to find a believable excuse. "Well you see Sweeitie, I..." She hesitated. "I...don't want anyone barging in here when I am putting on a new dress, it helps me...to stay concentrated so I can find any flaws in it. Yeah, that's exactly why I locked the door!"

"Oh, that makes sense!" Sweetie said as she started to walk into the kitchen. She noticed Rarity not coming and peaked her head around the door. "Rarity, are you coming?" She said anxiously.

"Just, hang on a minute Sweetie Belle, I have to..use the little filly's room." She smiled as her excuse-making skills were starting to improve.

"Alright." Sweetie said. "Oh, and Rarity?"

"Yes, Sweetie?"

"You might want to change your diaper while you're in there, 'little' sister." Sweetie giggled and galloped away. While Rarity stood there in shock.
