Meh, might as well write a short story.

Rebecca woke up one morning feeling tired, just like any other day. Little did she know it would be a day like no other. She started by getting washed up in the shower.

She ran her hands through her long brown hair and let the water pelt her skin. It felt nice and helped her shake off her grogginess. She stretched when she felt a tingle, something small that shouldn't catch her attention, yet something was off.

She looked down to see her pussy wasn't a pussy anymore! It was an anus! Rebecca was shocked. She felt her rear to find her missing vagina was there. Her holes had swapped!

And this would only be the start of her strange day.
