Warming Up

Warming Up is a very explicit shipping fanfic for My Little Pony Friendship Is Magic.

A particularly nasty winter comes to Ponyville. Worrying that Spike would freeze to death, due to him being a cold-blooded creature, Twilight suggests that Spike sleeps with her on the bed. However Twilight discovers that Spike has a crush on her, having a diary filled with explicit, sexual fantasies that he wanted to do with her. Touched, Twilight and Spike began having sexual relationship.

Unfortunately the others find out and tells Princess Celestia. Because Spike is below the age of consent, Twilight is charged with pedofoalia and Spike is placed under care of Fluttershy. Spike begins to suspect something is wrong when Fluttershy starts having feelings for Spike, with the two eventually having sex. Things go worse from here.

This is very much a porn with plot.

=== Tropes: ===


 * Kick the Dog: Twilight, when she's charged with pedofoalia.
 * And Spike, when Rainbow Dash (and subsequently Pinkie Pie) rapes him.
