Centaurs With a Twist

"I wish," said Jon, "that until I wish otherwise, everyone in society was a centaur. However, the gender of a person's horse half would be the opposite gender of the human half, so men would get pregnant and give birth to babies, while women would have penises and father children. Also, nudity would be considered normal and neither gender would wear clothing." There was a flash and Jon felt his body change. The change was sexually pleasurable and, as it finished, Jon experienced his first female orgasm. His new horse body possessed a blonde tail and a light gray coat. Jon looked in a full lenght mirror, turning around and flicking his tail up in an attempt to see his new genitals, but without much success. Giving up, he looked around his room to see what had changed. He didn't have a normal bed anymore and his posters of half naked girls were replaced by nude female centaurs. He decided to go to bed and wait for the morning to see what else had changed.
