Maid Just for the Readers

Dear Fellow Princess, Celestia,

Me and Rarity are both really thankful that you decided to send us to Earth. It's a shame that we have to leave tomorrow. Anyways, the human that you chose for us to study was a really interesting being. He was kind of objective to mine and Rarity's presence at times, but I think that's only because we showed up so suddenly. In the studies that you sent us to do, he certainly wasn't a slouch. Not quite on par with a stallion, but he was still very good. AT least, that's what I'd assume. After a bit of activity that I can't quite remember, I kind of passed out. Sorry. All that I can remember is that whatever he did felt amazing. If you need any more information, you can contact Rarity. I'm sure that she has more input, given that she was conscious the whole time.

Your fellow princess, Twilight Sparkle.

Dear Princess Celestia,

The studies that you had us do on human mating habits were certainly something else. To make a long story short, after a bit of coaxing, the human that you had us study really warmed up to helping me and Twilight study. He was amazing in every sense of the word. I'd even go so far to say that his anatomy is more suited to my tastes than a stallion's. After a bit of a scare, we've happily confirmed that there'll be no long term repercussions to our studies.  Anyways, me and Twilight have said our thanks and goodbyes, and we're ready to be sent back when you're ready to send us back.

Your faithful subject, Rarity.

Celestia lay down the two notes that she had received from Twilight and Rarity. After a few moments of consideration, she decides what she has to do from here.

"Luna!" She shouts to her sister. "How'd you like to go on a bit of a trip with me?"

"We'd be delighted, sister!" Luna says, entering Celestia's throne room. "Where to?"

Celestia gave a few moments of hesitation, before speaking up.

"A place that I recently received some... Interesting information on." She says, cracking a mischievous smile. "Would you like to accompany me?"

"Absolutely, sister!" What will we need to bring?" Luna asks, excitedly.

"Just some outfits from Lyra Heartstrings." Celestia replies.
