It was an average spa day for the both of them. Young healthy mares just hoping to have a relaxing day at the spa, hoping to unwind and talk about Ponyville and its in habitants. But, while they were ordering their day the new intern, Lily Spring, accidentally gave them the wrong soap to use. Not a problem besides spending an extra bit and smelling differently, right?

Well, the soap that she gave them was called The Red Rose and White Lotus soap. What it does is it heighten's a pony's sexual hormones. Usually it is used by failing married couples who want to spice up their relationship.

As their soak progresses they become more and more attracted to one another.
