"But he's my brother!" Ryan was torn - he did not want to abandon his little brother to becoming an animal! Yet it was already obvious Johnny was no longer human. He looked more like the unborn foal the centaur said he was becoming. Tears streamed down Ryan's face, and he finally started to relax his embrace when a sharp pain in his belly made him start. His chest hurt for a moment, nd he shuddered before all went calm.
Dazed, he leaned back and found that the umbilical connected to Johnny's belly had extended a branch into his! He felt sleepy, and soothing thoughts of being cared for, of being remade into something beautiful, filled his mind. Ryan was dimly aware of getting smaller, of being lifted, and then pressure and darkness before he and Johnny floated in warm fluid. Awareness dwindled to simple existence, a sleep-like state where he dreamed of running through pastures on four hooves, of eating sweet grass.
His long dream was interrupted by pressure, and he was squeezed out of a tube of slick flesh into bright light, warm air, and soft straw. Arms caught him and lowered him slowly the ground. A voice said "That's the other one. A filly this time. They will make a nice matched pair."
