"Is this what you really want?"
It felt weird to be asked by their second oldest to be babied again - not that Marge was complaining in the slightest - the idea of having sweet little Lisa back in her arms after all these years felt very comforting and reassuring. It was possibly a sign that her daughter wasn't growing up as fast as she had first imagined, and if it meant doing this little activity to further her bond with Lisa, then she'll happily do it.
A moment in, and Lisa and Marge entered Maggie's bedroom. The two stood in the middle of the room, with Lisa ocassionally dipping her head and forcing her gaze away from her mother before finally finding the courage to speak. "It's suposed to help the people involved relax, according to a study on the Internet; it helps the people involved decrease their stress levels, build stronger bonds and it provides a sense of escapism from the torment of modern life."
"I suppose so, sweetie." Marge responded with a light hum, a confident smile grew across her lips. "If you've read it on the Internet and did your research, then we'll give it a shot. If it doesn't work, then that's that."
"Oh," Lisa smiled back, "And another thing; I don't think there's any of Maggie's diapers that are going to fit me, so I might need some adult diapers instead."
"That's nonsense, Lisa." Marge replied, "You'd be surprised at how stretchy Maggie's diapers are. They'd fit you perfectly."
A single diaper was taken from the changing table; instantly revealing the sudden large size of the padded undergarment to Lisa, who's smile had dropped to a look of wonderment and slight embarrassment. "That's a little larger than I expected," She nervously giggled.
A silence dawned over both Lisa and Marge, with Lisa slowly climbing to the top of the changing table without prompt, leading Marge to slowly undress her daughter. Her red skirt, shoes, pearls and basic white panties were removed leaving the eight-year old virtually naked on the table. The diaper was unfolded and was expertly laid underneath Lisa's backside, the tapes soon followed and were tighly planted on the front with ease from Marge's years of experience.
The second part of the change came in the form of a familiar red pacifier that was quickly sunk in-between Lisa's lips, thanks to Marge, resulting in her starting to suckle on the invading object with her worries and doubt's slowly fading into the back of her mind. Her body felt limp, her legs were spread outward thanks to the diaper's thick absorbent layers and her mind was riddled with the conflicting thoughts on what she was about to participate in.
And finally, Marge had pulled out one of Maggie's blue onesie's. The onesie itself was dipped over Lisa's head and arms while it fell and lowered itself down to her crotch, barely covering the thick diaper that she was wearing.
By slowly leaning up, Lisa had realized that she was now in Maggie's position. Her desire for this had been building up, and now she had the opportunity to relax and act accordingly.
What's the first activity that Lisa decides to do, now that she's a baby again?
