"Transform...I think?" This was all so confusing to Rachel.
"Ugh...now I have to change you somehow." Cassie frowned.
"I know! Switch our ages!"
"Uh..are you sure...well...ok, for your transform, we'll switch ages."
Rachel felt a tingling sensation all over her body. It wasn't at all unpleasant; actually it felt rather nice. Before her very eyes, Cassie grew several inches, her figure filling out, and her features becoming more mature, until she was once again a girl not quite 18 years old.
Not surprisingly, Cassie seemed greatly relieved. "I didn't know what I was going to do...wow, you're really cute, Rachel."
Rachel blushed. Her clothing was loose on her body, and she felt oddly insecure. Cassie had always been taller than her; now that she'd been regressed, the size difference was even more pronounced. "You...think so?"
Her friend set aside the pillow and pulled her into a hug. Rachel was acutely aware of Cassie's breasts, and she felt her face burn. "Definitely. But why trade like this?"
"Uh...well, my folks are out of town, so I thought I could get away with being a kid longer than you could."
Cassie smiled and kissed her friend on the top of her head. "Thank you. But how are we going to turn you back?"
Rachel thought about it a moment. "Transform or Dare?"
"...uh...dare?" Cassie looked a bit dubious.
Rachel didn't bother to set a dare for her friend. She could feel something was wrong. "Nope, guess there are no tag-backs."
"I guess that would be too easy, huh? Well then, we'll have to figure out how to get the curse back. Which means we need to hand it off to someone."
Rachel smiled. "This could be fun!"
"Mhm! But first we need to get you clothes that fit better. To the mall!"
