Time passes

Year after year it was the same thing Misty would turn Lara back only for her to spend the next few days masturbating and then ask to be transformed into panties again until about ten years after they started this that Lara said she would leave it up to owner when she should come back, Kate and Abby had come to understand Lara was happier this way deciding not to interfere with what she wanted any-more even through they both missed her, so when Misty was deciding what to get Tara for her eighteenth birthday she decided it was time to pass on the responsibility given she was nearing her mid fifties and she didn't want to die with no one to look after her, so picking out a new more modern style for Lara putting her back in new condition Misty packed her into a nice box and got herself ready for the party.

"Thank you for coming auntie" Tara said giving Misty a big hug, "i wouldn't miss today for anything angel and i brought you something special but you will have to wait until after the party" Misty explained, once everyone else had gone home the whole family sat down together in the living room , Misty had already told Kate and Abby what she was going to do and they had agreed that its a great way to keep Lara safe and in the family, handing over the box to Tara who was a little surprised at the contents but even more shocked when Misty touched them and they changed shape, "how did you do that?" she exclaimed, deciding it was her responsibility to explain Kate said "it might sound surprising but these panties are our family treasure and our biggest secret so now it will be up to you to look after them until the day you pass them on", after an explanation of how the transformation worked Tara thanked everyone for a great birthday and went to bed.

"Do you think we did the right thing keeping the truth about Lara a secret?" Misty asked, "yes i think its what she wanted and why she asked to leave transforming her back up to the owner" Kate replied, "but without knowing who and what she is wont she never get turned back" Abby interrupted, "think how many times we accidentality transformed her over the years before this, when a owner as Lara put it takes a special interest in her i'm sure the truth will be revealed" Kate answered "but i do think we should leave a time capsule for her to help her regain her memories when the time comes".
