"I have a spell that can temporarily turn you two into futanari," said Liz, "just long enough for you two to get one another pregnant."
"Blech! I don't want that thing back. I don't even want to be reminded that I was once one of those disgusting male creatures!" said Tommie. Susan wasn't sure if Tommie had become a true misandrist, but she often cursed her former sex. Susan's theory was that Tommie got some sort of perverse pleasure out of pretending when she was first transformed, and accepted it as the spell adopted it into an actual part of the new her's personality.
"I find the idea a little gross as well," said Susan.
"I can use a spell to find a few people who wouldn't mind restarting their lives and being transformed into your lesbian daughters," offered Liz.
"Or how about this?" said Liz, as she pulled an adult toy from her purse. "This is an enchanted strap-on. You can take turns wearing it. Even though it's just an imitation, it will allow you to impregnate one another. It also comes with perception and world modifying magic, so you don't ever need to worry about anyone asking any awkwardly detailed questions about where your future daughters came from."
