"You are hungry? Are you sure?" Tiff asked
"I know it sounds weird, but I can still feel some things related to parts of my body that have disappeared." Katie said
"My goodness, that seems like a problem. But now, how can I get you back to normal?" Tiff asked, so she put Katie down and went looking for a potion to solve the problem.
Katie rolled to her side but bumped into one of the shelves. The impact was enough to make one of the bottles fall. Coincidentement, the vial fell with the neck down and ended up penetrating Katie's vagina. As she struggled, the potion inside seeped into her, and by the time Tiff had taken it for her, half of its contents had already been inside Katie.
Seconds later, Katie began to transform. Her body began to lengthen and it felt like the upper part of her body was growing again, But in the new top, instead of head, arms and breasts, formed another bottom half with a vagina and an ass. "What's happening to me Tiff?" she asked
"You were an ass, now you're two asses." Tiff said
"The thing just keeps complicating, and now what do we do?" Katie asked
"I do not know you, but I had an idea and want to try." Tiff said. Then she took more of the same potion that made the cock grow between her shoulders and injected it just above her vagina, where it grew another cock and balls.
"Tiff, what are you up to?" Katie asked
"Don't worry, I know you will like it." Tiff spoke through her vagina, now hidden behind her new pair of balls. She held Katie right in the middle, with her two cocks rock-hard. Then, using the new cock between her legs, Tiff started fucking Katie's bottom pussy.
"Wow Tiff, I didn't expect that, but I have to admit it's very good." Katie said, finding that she could talk through the new upper vagina.
"I know, and here is more." Tiff said and started fucking Katie's top pussy with the cock between her shoulders.
Both were unable to last long with the double stimulus they were receiving. "This is amazing, I can't hold on anymore, I'm going to cum" Tiff said.
"Mmmmmmmmm" That's all Katie could say with her two full vaginas.
They both came, and the cum one that came out of Tiff's two dicks joined in the middle of Katie's body. At the end of her orgasms, Tiff pulled her dicks out of Katie and saw the extent of the damage. Right in the middle of Katie's body, it had filled with so much cum that it looked like she was pregnant.
Satisfied and with her totally flaccids dicks, Tiff said "Now we better look back at what we were looking for."
When Tiff looked back through the vials, something she didn't expect happened. What happened?
