One of the various strange fetishes Teri had encountered was called unbirthing. Basically, it was (through some means) being absorbed into another woman's body, and becoming their unborn child. She found the idea strangely arousing, and imagined what it would be like to not simply be pregnant (something she'd always been curious about), but to be returned to the womb herself, fully aware and with her adult mind.
Though, to be honest, she didn't really want to be a helpless baby again. Maybe if she could shrink to the size of an unborn baby instead? Well, she supposed being somewhat younger would be ok, too. She figured she should unbirth someone else first.
A crazy thought popped into her head, and, at breakfast, she started up a conversation with her mother, Natalie. Natalie looked a lot like her daughter, though older, and with a better figure and larger breasts. She looked tired a lot lately, and Teri could tell her mother was starting to feel depressed about getting older.
"I wish I could ask my Mom any question, and she wouldn't think it was weird, and answer me truthfully."
"What was that, honey?" Her mother turned her head to face Teri, as she was cooking breakfast.
"Oh, I was just wondering. If there was a method by which people could become young again, but they had to become really young, what's the youngest you'd be ok with being again?"
Natalie seemed to chew on that for a moment. "Well...I mean, I'd grow up again, right?"
"Sure thing." Teri nodded.
"Then I guess it wouldn't be too bad if I had to become a kid again. Just as long as I could walk and talk, and not have to wear a diaper or anything. Or wet the bed." Natalie made a face. "I don't know, two or three seems really really young. Maybe...four?"
"I wish my Mom would shrink down to the age of four and be happy about it, not freaking out, and just accepting the change."
Natalie seemed to shiver, and she turned off the stove. She looked at her daughter oddly. Time was moving backwards for her, and quickly. Her wrinkles vanished, as did her grey hairs. Her face regained the softness of youth, and she lost a lot of weight, her figure slimming and her breasts shrinking in size. Soon her bathrobe was looking loose as she began to lose height. Soon she was no older than Teri herself, but that moment quickly passed as she became a young teenager, then a tween, then a girl of ten...nine...eight...seven....
Within moments, Natalie shrugged out of her clothing, and stood there naked. She was positively adorable, and she smiled up at her daughter cutely. "Oh this is wonderful, Teri!" Her childish voiced chirped. "I guess this makes you the Mommy now!"
Teri got up and walked over, scooping up her Mother. "I suppose I have to take care of you now."
Natalie giggled. "At least you don't have to nurse or change me!"
"Oh, do you think you'd hate being nursed again?'
Natalie seemed to think about that. "No, I guess that would be ok, but I'm kind of big."
"I wish you would shrink to the size of a newborn baby, and not think there was anything odd about it."
Natalie dwindled further in Teri's arms, not getting younger, but definitely smaller, until she was the size of a wee babe. Teri then carried her into the living room and settled down on the loveseat. "I wish my breasts were full of milk Natalie would find delicious."
She felt her breasts swell, and she opened up her own bathrobe, then put Natalie to her breast. Her shrunken parent eagerly took a nipple into her mouth, and began to nurse, her tiny hands trying to nead her breast.
Teri found the sensation quite pleasant, and sat there with her Mother, enjoying the intimacy of the act, until she dozed off.
"Teri! I'm done now!"
Teri woke up, and smiled at the beautiful child in her arms, who was wriggling and trying to escape her grip, though she was far too small and weak to do so. "Oh so you are! Well, this was fun, but now I want to try something else."
"What's that, Teri?"
"I wish you shrank even more, to the size of an unborn baby of five months. I wish I'd become pregnant with you."
Natalie squeaked as she shrunk again, and she struggled more fiercely, but Teri felt a warm sensation as the miniature girl seemed to meld into her skin. Within minutes, Teri's belly had expanded, and she felt her Mother moving around inside her body!
"Oh..that's..." She thought. "Uncomfortable!" She giggled. She got up slowly, and observed how her now pregnant body affected her. She soon had to use the bathroom, as there was much more pressure on her bladder. After going to the bathroom, she decided she didn't really like being pregnant all that much.
She wondered what to do with her Mother.
