Rarity has been going to the Ponyville Spa for many, many years now. Racking up frequent client deals, sharing such bargains with her friends, and enjoying the feeling of being tended to by the skilled spa ponies, Lotus and Aloe. But during one such visit, the prissy mare not only happens to be in heat, but the eager spa pony twins have just the special treatment for her. All Rarity needs to do, is sign a special waiver.

This is a Commission for Tailsic.
