Princess Twilight Sparkle walked through the duel suite, both rooms connected, she and Trixie were sharing with Shining Armor and Cadence for the weekend. She had just woken up from an afternoon nap because she was hearing strange noises from Shining and Cadence's room. She got to the door and was right about to knock when she heard another voice in the room.
"Faster Shining!" Trixie's voice
"What the hay?" Twilight said, silently hoping she wasn't heard.
"I'm trying!" Shining Armor yelled back, causing Twilight's face to turn bright red.
'WHAT THE ACTUAL HAY?!' She thought as she continued to listen to the two inside.
"Hurry almost there!" Said Trixie some other noises could be heard from behind the door.
"I know!" Shining replied, causing Twilight to leaning her head to the side of the door as she continued to listen intently.
"HIT IT RIGHT THERE!" Trixie exclaimed loudly.
"I KNOW HOW TO DO IT TRIXIE!" Shining yelled back frantically.
"Give that thing to Trixie now!" Twilight heard her wife shout. The Princess of Magic couldn't stand it anymore. The door swung open as Twilight reviled herself to the two ponies, who were caught in their act as she pointed at them.
"GOT YA! I can't believe you two would …?" Twilight began to rant only to stop as she saw both ponies running around the room, chasing a rather large horsefly. Both Shining Armor and Trixie had fly swatters in their magical grasp.
"There it goes!" Trixie yelled as they chased the insect into the bathroom.
"Hold it steady. Steady.......... GOT IT!" Shining Armor yelled in triumph as a loud smack was heard.
"Man, thought we'd never get that thing." Shining said as he trotted out of the bathroom.
"Indeed, to think a puny insect could be a challenge for the Great and Powerful Trixie. It is to laugh!" Trixie said haughtily as she laid the flyswatter down.
Twilight was dumbstruck, and in her moment of shock she looked down at the carpet like it was the most interesting thing she had ever seen.
"Oh Twily, didn't hear you come in. You wanted something?" The white unicorn asked, only to get a stammering response.
"O-oh I was… um… Well…" She didn't know what to think anymore. They were just chasing a fly! The purple alicorn felt like the biggest pervert who ever walked the face of the earth for assuming such terribly perverted things about her wife and brother, not to mention the guilt she felt about even entertaining the idea of them cheating on her or Cadence.
"What's wrong?" Shining Armor asked curiously as he watched his sister continue to babble incoherent words that seemed to be the beginning of sentences that she couldn't finish.
"N-NOTHING! W-what made you say that?!" Twilight said quickly, making Shining a bit more concerned about her mental welfare.
"Okay........ Uh, Cadence will probably be back from the spa in a few minutes, so how about we all go to that restaurant the hotel has?" Shining said as he eyed his sister carefully.
"That sounds great. Trixie worked up an appetite chasing that blasted fly around." The blue unicorn said as she rubbed her growling stomach.
"That's sounds good! Lemme go freshen up!" Twilight said, rather loudly, as she turned around and trotted out of the room hastily in embarrassment.
"I can't believe I thought that! Trixie and Shining would never do that to me and Cadence! I don't know what got into me. I mean, I should know better than anypony that Trixie wouldn't go for Shining." Twilight ranted to herself, mentally slapping her perverted mind, she marched out of the suit. Out in the hall she saw Cadence walking up. She looked at her sister-in-law and felt a suspicion creeping up, but given how well her last suspicion turned out she immediately ignored it.
"Hi Twilight, how's your day been?" The pink alicorn asked as she walked up.
"Oh fine! Nothing unusual at all! Ever!" Twilight blurted out.
"Uh...... Okay?" The Princess of Love said as she cocked her head to one side in confusion.
"Shining wants to go to that restaurant downstairs for dinner!" Twilight all but shouted.
"Okay? Twilight are you alright?" Cadence asked, only for Trixie to open the door.
"Twilight, the last time Trixie checked you can't freshen up in a hallway."
"Right! So I'm just going to go to the bathroom!" The purple alicorn said as she ran off to the bathroom at full speed and slammed the door.
"Why do I get the feeling Twilight's got some kind of secret?" Cadence said as she looked over at Trixie.
"Meh. Trixie stopped trying to figure Twilight out long ago. Her and her partying pink friend."
