Written in 3(ish) hours on the 22nd for Kloudmutt's Tiny Xmas Contest. Don't know if I'm allowed to link it so I wont.

It's Hearthswarming Eve and Scootaloo is spending it with her Dinky and said fillyfriends family.
When it's time for presents, the opportunity arises for Dinky to try out a new spell she had been working on.
One that requires Scootaloo, her bedroom and her bed. And a gemstone being inserted up her ... well, it's mature for a reason.

Also they're aged up, but not enough to avoid having to warn, Foalconic Futa.

What do you mean that's not your OTP? That Scootaloo and/or Dinky belongs to someone else? Well your wrong, and deep in your heart you know it.
