On a Sunday Rarity invited Fluttershy to a relaxing day at the Spa where the two usually hang out. Without hesitation Fluttershy said Yes and the two ponies made their way to the Spa late that afternoon. The two took a massage and chatted as per usual about how their week went. Rarity subjected that they take a bath afterwards before finishing their day there and Fluttershy agreed. Though neither of them knew that they weren't exactly gonna leave the spa that day...
Later on Rarity and Fluttershy finished their massage and the Spa ponies, Lotus Blossom and Aloe prepared the bath room for them and as soon as Rarity was done, she went straight into the room where the bathtub was and Fluttershy followed her momentarily. However, as soon as Rarity got in that room there was a surprise waiting for her and Fluttershy.
"Um, Lotus?" said Rarity "Aloe? Why is the room all dar--"
Rarity was interrupted by Lotus who grabbed her mouth with a rag of chloroform.
"Mmmph!!" Rarity kept struggling until she slowly got knocked out.
"Rarity!" Fluttershy hurried in just to be caught by Aloe who also covered her mouth with a rag of cloroform.
"Mmmmph!! Nmmmph!" Fluttershy struggled as she too went unconscious.

The effect of the chloroform was weak however so it was only gonna last for some minutes.
"Let's tie them down before they wake up..." Lotus said to Aloe as she grabbed a roll of tape.
As the girls were knocked out, the Spa ponies started tying them down. Lotus started wrapping Rarity's legs together only leaving her hoofs and ankles bare. Lotus then handed the roll of tape to Aloe who started wrapping Fluttershy's legs together also exposing her ankles and hoofs. The two ponies then grabbed rope to bind the two girls' forelegs behind their backs. Fluttershy's wings were also tied down to prevent her from flying, and Rarity's horn got a ring on it that'll block her magic.
"That won't be enough tape, Lotus" said Aloe "I'll just use a cloth..."
As Aloe went to grab a cloth to gag Fluttershy, Lotus grabbed the last piece of duct tape and placed it on Rarity's mouth who was soon gonna regain her full strength. Aloe hurried back with a grey cloth and a few napkins. She grabbed Fluttershy's mouth and put the napkins in and then cover her muzzle with the grey cloth.
"That'll keep them quiet." Lotus said as they both chuckled while watching the two ponies regain consciousness.
A couple of minutes pass and both start waking up.
"Hmmmm..?" Fluttershy slowly opened her eyes.
"Hmm?" A few seconds took Fluttershy to fully wake up to realise she can't move her limbs.
"Hmmph!" Fluttershy kicks Rarity's side who was sitting right next to her

"hmmm?" Rarity slowly woke up to the site of tied up and gagged Fluttershy. She moans trying to move her legs and speak but she is helpless.
"Well, well.. you're up..." said Aloe with a laugh
"Hmmph?!" Fluttershy quickly looked back and forth at the two ponies behind them and Rarity who was squirming.
"Sorry but, we can't let you go now." said Lotus.
"MMmmmphh!!" Rarity continued squirming.
"We hope you like tickle tortures... because you're getting that instead of a bath" Aloe said looking rather smug.
"Yeah... there is no hot water anyway..." Lotus added.
