Cogs finally is forced to reveal to Lavender that he is a changeling. She is angry with him for not trusting her with his secret, but now she knows why they have not been able to conceive a foal. There is a way though to do it by proxy, but in order to do that, Cogs needs to take on the form of an attractive mare. He is not too thrilled about it, but Lavender makes it even worse when she gets a little carried away with prettying "her" up even further. Cogs suspects that its her way of getting back at him for deceiving her for so long, and suffers in silence... mostly.

Lavender's horn is still weak, but she can hold a brush now. This is an illustration for the "Foals" chapter of my story, "Change of Life" - https://www.fimfiction.net/story/14.....change-of-life
