“Daddy, my tummy hurts!” Susie whined, breaking wind noisily once more (much to big sister Barbie’s amusement.) A thick, cheesy stench emerged from the back of her diaper, blanketing the area.

     “It’s OK, darling,” Dan said, kneeling on the floor next to her and stroking her back in a vain effort to comfort her. Her partially regressed mind knew what was happening, knew what she had to do to stop it... but she was completely unable to make her body obey her commands. She felt her backside open against her will, a warm, mushy dollop of poop firing flatulently into the seat of her diaper.

     “Oh NO!” Susie cried, still possessing just enough of her adult awareness to realize what was happening, be fully aware of her fundamental loss of control and the loss of status that resulted from it... and even as her bowels clenched, unleashing another involuntary, explosive splatter into her pampers, Susie began wailing like a spoiled toddler.  

     “WWWWWHHHAAAAAA!” she cried, her stomach tightening, her guts cramping, buttocks parting to accommodate a big, noisy load that came thundering out of her and settled into the seat of her diapers in a hot, mushy pile.

     “WHHHAA! IT NO FAIR!” she bawled, pounding her fist into the floor even as she continued to uncontrollably mess her already heavily loaded pampers. “I NO BAY-BEEE!” she squealed, even she noisily deposited another load of mucky brown poo-poo into her pants.

     At last her bowel movement was finished, her cramping abdominal discomfort relieved. But her tantrum was just beginning, and as she sat back on her bulging backside, the load inside her diapers sandwiched between her buttocks and the floor with an audible squish, she felt the hot mess smear across her rump and push up inside the cleft between her cheeks. She looked up at him, heart-meltingly adorable with her lips quivering and her eyes brimming with tears, and exploded into a full blown fit.

     “WWWWHHHHAAAA! NO FAWIR! I BIG GIRL! I AM! I A-HA-HAMMMM!” She screamed, rolling onto her back to pound her fists and stamp her feet against the floor, shrieking and crying, the mess in her diapers getting increasingly squished and spread with her every move. Before he even realized he was doing it, Dan was down on his knees next to her, rubbing her tummy, stroking her hair and cooing softly to her in an attempt at calming her down.

     “There there, honey,” he said soothingly, moving his strong, broad hand against her tummy in a soft, circular motion. “Shhh... it’s OK, sweetie. Settle down. If you settle down then I can change your diapers for you,” he said softly, smiling a little when she slowly stopped her fussing. She looked up at him, tears still streaming down her face, and he smiled reassuringly at her.  

     “That’s right babykins,” he soothed, taking her hand in his and kissing it gently. “Just relax and let Daddy change you out of that nasty ol’ diaper-- that’s what you want, right?”

     “Uh huh,” she said, sniffling, still crying, but in control of her emotions, at least for the moment. Dan bent down and kissed her gently before running to the next room to get the changing supplies.

     From her spot nearby, Barbie watched the proceedings with mixed emotions. It was rather amusing to see baby Susie have her little accident, and the tantrum that followed had been most entertaining... but seeing Daddy being so intimate with her had Barbie feeling a childish stab of jealousy-- she vowed to keep a close eye on this diaper change, remembering what had happened during her last change with a sexy shudder.

     Dan made sure to hustle back, not wanting to leave the girls alone for too long. He quickly set up, spreading out a plastic mat and guiding Susie onto it. “It’s OK, honey,” he assured her, giving her hand a reassuring squeeze, Blushing, Susie popped her thumb into her mouth and slurped it noisily, eyeing him hopefully, the last embers of her adulthood flickering with abject humiliation. With his supplies at hand, he tore open the tapes on the front of the diaper and gently lowered it, revealing that he had his work cut out for him.

     “Oh boy,” he said, mostly to himself, when the full magnitude of her gooey brown mess, caked thickly across the seat came into view. A corresponding smear was layered just as thickly across her tight little rump, and a thick wedge had filled the cleft between the rounded hillocks of her rump.

     Barbie’s assessment was more direct: pinching her nose shut, she gave a cheeky grin and declared “EEEWWWW! MESSY!” then giggled naughtily when Daddy shot her a look as he pulled a baby wipe from the nearby container.

     Dan went to work, lifting her legs and giving her mucky bottom a wipe, Susie groaning with embarrassment when the cool cloth hit her skin. It felt wonderful to get clean, but the shame of her situation was too much, even for her partially diminished intellect, and her only source of comfort was the thumb in her mouth. She squirmed and pouted, fat tears rolling down her cheeks as she wallowed in self-pity.

     Meanwhile, Barbie looked on with amusement. Her regressed mind was still somewhat envious of Susie’s position... but she couldn’t help enjoying the schadenfreude of the formerly proud Susan, who just that afternoon had been a sexy, mature woman teasing poor Barbie about her new lot in life getting hoist by her own petard. She was enjoying the reversal of fortune, and she couldn’t help rubbing Susie’s nose in it just a little.

     “Oh Daddy, she stinks worse than anything!” Barbie said, fanning her face and giggling in full brat-mode.

     Susie whimpered and hid her face, squirming as daddy discarded the wipe and went to work with a fresh one, passing it up between her butt-cheeks to get at the mess caked inside. “You know, Barbie,” he said archly, looking up at her sardonically, “I seem to recall that your dirty diapers don’t exactly smell like Chanel No. 5, young lady.” He smiled, chuckling a bit when Barbie reddened and looked away, her teasing backfiring on her. It wasn’t much fun, she realized, to have her messy diapers described to others, and Susie, her tears no longer flowing, looked up at her with a strange expression now-- not one of amusement or embarrassment or even anger, but one of kinship.

     “Now, if you’re done being a naughty girl, why don’t you make yourself useful... come over here and give your baby sister some comfort,” he admonished gently, discarding the cloth and going for yet another one before getting back to his monumental clean up.

     Still pouty after being embarrassed, Barbie scooted over on her hands and knees, her swollen diaper butt crinkling in the air behind her. She took up a kneeling position near Susie’s head, which she lifted gently and helped settle into her lap. Susie peered up at her with huge dark eyes, nervous, yet grateful. Barbie sensed that this girl staring up at her and sucking her thumb was not the same person who had tormented her earlier, and instantly felt guilty for trying to embarrass her.

     “’S OK, Susie,” she said, stroking her cheek gently. “Big sis will hewp take cawe of you,” she assured her, bending down to kiss her forehead.

     “That’s better,” Dan said with a smile, thankful that Susie had settled down and was now still, making it much easier to finish wiping her off before he oiled and powdered her tushy.  

     Meanwhile, Susie gazed up at her new Big Sister (as she called herself) and was enraptured. Any thought of Barbie as dorky or inferior had been totally forgotten... the girl above her seemed so cool and sexy and confident and mature... Susie felt like a silly little girl in front of her, and she knew right there that she wanted to be just like her Big Sis. Popping her thumb out of her mouth, she fixed her with a shy little smile and whispered in a tiny voice “Fank oo, Big Sister Barbie,” her heart soaring when she was rewarded with a sweet little kiss on the lips.
