As the stallion's mating finally came to an end after what seemed like an eternity, his cock softened, and he was able to withdraw from the mare. Then his body began quivering all over, and he staggered on all fours. There was a pile of lumber over to one side that he hadn't noticed before. He seemed drawn to it. It was getting hard to breathe, and Ed felt stiff all over. He couldn't move, he couldn't breathe. He was a horse, but he should be a man or a boy at least. It made no sense. It was getting harder and harder to think.
The sound of a fresh two by four echoed in the pasture. The mare glanced and saw that the stallion was gone. Ed was just another board stiff - stiff board. She swatted a tile with her tail, and turned back to watch for her next human male victim.
It seemed like an odd way for her master get lumber, but then he was the master, and a powerful wizard to boot.
