Sunflower Showers is a new pegasus in Canterlot who has befriended the extremely wealthy son of a quill and sofa magnate and is taken to a mysterious restaurant. The dinner is absolutely delicious and high class, but the "dessert" takes on a role reversal that has Sunflower on edge.
Orchid isn't mine, she belongs to some anon on /mlp/ who has surprisingly little digital presence to credit.
Warnings: Vore, big pony (skip to Dessert if you just want the fun stuff without an infodump.)
