From a collab session with The Lutece twins. Modified some for better flow and grammer.

After a nasty breakup, Rarity invites Fluttershy to her place, intent on giving her a gift. Things quickly grow lewd, and then large and destructive.

Warnings: Futa, Excessive cum, Hyper Expansion, Multi-cock, Cum Inflation, Destruction of Propety, what-the-fuck-is-this-shit growth, and at least 5 zoning laws broken

If you can't tell yet, Futa Rarity is my favorite thing ever.
