Twilight, being the avid bookworm she is, is working on an erotic novel called 'The Colours of Love", but is lacking in the knowledge she needs to write it well.

When she catches Rainbow Dash reading a rejected sex scene, the two unanimously decide to work together to improve the book, and it only escalates from there.

Anthro ponies, and clop. Contains female x female. May have more mature themes (aside from blatant sex).
