Rainbow never really enjoyed ponies touching her hooves, and she seemed to have developed this odd distaste for spas in general. Rarity had never really asked about it, but when Rainbow comes to her for assistance because she can't stand going to the spa, and her more physical problems become too much to live with, Rarity becomes determined to figure out the root cause of Rainbow's reluctance. Rainbow is like steel, though, and Rarity was the last pony she'd ever open up to.

All things considered, Rarity's magic wasn't going to last forever. Rainbow would eventually build up a natural resistance to the spells her friend had cast on her, and would then have no choice but to visit the spa in order to both stay looking good, and feeling awesome. The only question is, would she bring herself to go through with it?

A side question, what other treatments would Aloe and Lotus have in store for this brand new, and most anticipated customer?
