Flurry Heart wants a baby sister and her parents would love to give her one, but there's just one problem... Princess Cadance is infertile. Good thing Flurry has a womb to spare. With the help of her father and a raging heat, nothing will stop her from finally making her dreams come true!

Just so long as she conveniently ignores that it's her daughter as well.

Contains: Foalcon, Incest, Impregnation, Estrus, & Lingerie.
