As the rebels left, Sassy galloped into the woods. She could feel contractions now. Her time was close. When she felt she had reached a safe distance, she stopped in a glen. Instincts took over. Sassy laid on her side and pushed. Promptly, the foal that had been Anya slid out of Sassy's pussy, which had been getting a lot of use that day.
Sassy looked at Anya. The foal, a palomino filly, was struggling to her feet. Sassy got up as well. She nickered softly at the foal.
"Anya?"
"Yes, it is me," the foal neighed back. Sassy sighed in relief. "I did not realize just how powerful the amulet was, to transform me!"
"What do we do now?"
"Rest for the night and journey east in the morning. I will slowly get my magic back enough to transform to my true self. If I had not been the one to make the amulet, I would be stuck. But luckily, this is not the case." Anya stepped over to Sassy. "I apologize for the awkwardness, but I must drink."
"Oh!" Sassy suddenly remembered that yes, she was Anya's mother in a way, and as such, needed to take care of her. "Um. Do so, then." Anya ducked her head under Sassy, latching onto the mare's now full udder. As she drank hungrily, Sassy grazed. When they both had their fill, they laid down on the grass, snuggling each other, and fell asleep.
