Frustration in Excelsis 
Worldbuilding Addict
Shame on you, Sparkle!
EDIT: Also, I'm going to add the description in the tumblr post, not sure why it wasn't added:
[bq]Rarity: "I'm flattered but I really must decline!"
Twilight: "I was asking for someone else! There's a mare interested in you but she doesn't think you'd be interested."
Rarity: "Now, now, there’s no need for lying! I'm mostly surprised you two would consider 'spicing things up' so early in you marriage!"
Twilight: "RARITY STAHP"[/bq]
