Miriam and Zack, both 25 years old, were newlyweds and were on their honeymoon.
They arrived at their hotel room, after spending the whole day at the beach, where they decided to have sex. Everything was going well, until Miriam felt Zack take his dick out of her. She opened her eyes and was about to complain, but found herself face to face with another woman who was staring at her naked body.
"Who the hell are you? And where is Zack?" Miriam asked
"Miriam, it's me. For some reason I became a woman." Zack said. Half incredulous, Miriam looked more closely and realized that the face was really Zack's, with only feminine features.
"They were silent for a while, not knowing what to do in this situation until, without knowing that the same thing happened all over the world, Miriam said "Zack, now what? Do you think you'll be able to go back to normal?"
"Back to normal? I don't even know why this happened to me." Zack said
"I am uncertain about our marriage. you know i'm not interested in women. And I also want to be a mother, so I will have to look for another man." Miriam said, unaware that there were no more men in the world.
Before Zack could answer he realized that his dick was growing back. "See, I'm getting back to normal." He said a little excited, until he saw that there was a dick growing between Miriam's legs as well. The dick of the two ended up much bigger than what Zack had before was. The final touch was Zack's balls appearing in front of her vagina, while Miriam's vagina was sealed and a scrotum was formed in its place.
Now Zack is a futa and Miriam is a shemale. The two just look at each other, confused as to what happened.
