He did remember Jesse always saying how she really wanted a girl if they ever decided to have children. Who better to be her new baby daughter then her best friend? And also what better way to get back at her for her mean remark than to put her back in diapers alongside him. Plus he figured she’d make a great playmate.
Grinning to himself Mark grabbed the coin and made his wish.
“I wish that Rebecca was a three year old toddler and in diapers like me and that everybody except for me and Jesse thought she was my baby sister and would treat her as such. However Jesse would baby her the same way she babies me. I also wish that she still had her adult mind and still remembered her adult life.”
He didn’t want her to be an actual baby, that would be way too cruel and harsh given all she did was insult his diapers. All he wanted to do was give her a firsthand look at being in them, and also he really wanted to see how she would react to going from a fully independent thirty year old woman to a baby girl incapable of using the potty.
All of a sudden Rebecca began to shrink in size as she grew younger. The woman let out a cry of surprise as she rapidly lost height, her dress shrinking along with her body. The regression happened just as quickly as his own did and in less than a minute later a three year old Rebecca stood in her place wearing a toddler sized pink dress.
Confused as to what happened and how she became a baby Rebecca fell down onto her bottom and began to look around at how huge everything became.
Mark then watched Jesse pick up the now three year old Rebecca holding her over her shoulder, holding her back with one hand and her diapered rear with the other. Speaking of which from where his was standing he could see under her dress and smiled when he saw she was wearing a pink colored pampers disposable diaper.
“Heh who’s too old for diapers now bitch” he commented with a sly smirk.
“I wish that Rebecca knew about everything I’ve done so far and what I’m capable of” he said gripping the coin wanting to catch the newest baby up to speed as soon as possible.
After holding Rebecca for a few more minutes, and appearing to enjoy the experience of holding a baby girl even if it was her own best friend regressed, Jesse lowered her back down to the ground.
“So who’s the baby now?” Mark said with a smug look, standing proudly with folding arms.
She then turned to look at the other toddler, her eyes staring him down.
Turns out she…
