Mr. Cake never thought his Hearts and Hooves gift to his wife would last longer then the night. Now changed into a sexy young mare around Pinkie's age, "Angel Cake" has nearly a full week stuck in this body.

To make matters worse, today is the day Pinkie Pie and the twins come home. Is she ready to be a mother to the twins? What crazy shenanigans will Pinkie try to rope her into? She doesn't really find that shy stallion cute right?

Encouraged by her wife to experience as much as she can as a mare, coupled with her newly forming feminine desires, Angel is on a slippery road to do things she never would have dreamed of.

It would be so much easier if Cup Cake hadn't put that idea of a threesome in her head...
