Rarity went about the boutique, closing blinds and drawing curtains. The mood had to be just right for the sort of activities she had planned for the evening. When Pinkie showed up at her door all those weeks ago asking to spend the night she couldn't just turn her away. The Cakes were furious after a prank gone south exploded one of the ovens, and the bubbly ball of pink thought it would be best to give them some space. It had turned into a fun evening, at least until Pinkie convinced her to do something she'd vehemently deny in public.
"Just try it! I'm sure you'll love it if you just gave it a try Rari-Berry! Although you're colored more like a marshmallow but it doesn't rhyme as good."
"Pinkie, a lady doesn't do such things, it's so improper."
"But I do it with Rainbow all the time! Please just try it, I Pinkie promise never to tell anypony about it if you want."
She gave the other mare a long measured look. "Fine, if only it will get you to settle down so we can sleep."
From that night on she'd been a changed mare. Every week at the same time they'd get together and do it. The chime on the front door rang and the tell tale smell of baked goods followed their owner in.
"Hiya Rarity, ready to watch our kung fu movie?"
