Best of all worlds

His eyes fluttered open. Everything felt wrong. His body felt foreign, his eyes didn't want to focus. After an uncomfortable wait and a lot of blinking, he began to clear up. He looked at his wife. She was amazing. Her breasts stood out proudly, perfect. Even more perfect than he could have hoped. Her body was surprisingly strong, with perfect chiseled abs. His eyes trailed down to her penis. It was now larger and definitely not human. It looked like a horse cock, though not quite that large. Something tickled his bum. He turned to see his lovely feminine form and the horse tail hanging down, tickling him. He gasped and looked at his own genitals, only to find that he couldn't see it because of his breasts. He looked at his wife again and licked the delicious cum from his lips. He was now a she, and just as beautiful as his wife.
