you soon felt the girl being placed in a stroller, the mother securing her in with a strap across the waist which you heard lock with an audible *click*. you could see a little bit out the front, the strap slightly obstructed your view as the mother began pushing the stroller outside. you could hear the sounds of the outside world - cars going by, dogs barking, birds singing, the stroller wheels on the street - the sun beating down on the girl and her diaper - you - which soon began to heat up. eventually after about 30 minutes they reached the park and the mother lifted the girl out of the stroller and onto the ground - you were greeted by sand as the mother put her down in a sandbox to play with some toys.
the girl played for a good hour, getting quite dirty in the process - some of the sand even found it's way into the diaper. eventually you felt the girl begin to pee in you and the diaper eagerly absorbed the urine, swelling outward in the process. it was quite warm at first but eventually cooled as the girl continued to play, not even noticing that she wet her diaper. after sometime the mother came back over and picked the girl up - you watched as the ground zoomed away until a black hand came to rest on you - under the girls diapered behind - and carried her back to the stroller.
"oh, looks like somebody is wet! I'll change you when we get home honey" said the mother as she placed the girl back in the stroller. soon another *click* followed as she was once again strapped in and they began the walk back home. after about 10 minutes the girl began to fuss a lot, squirming around and squinting you into the stroller seat. the mother noticed and gave her a bottle, but she was not interested - she offered her a pacifier which the girl eagerly took and began to suck on. it soothed her enough but it didn't last. about 5 minutes later, you felt the girl lean forward and grunt. this was followed by her farting and soon a turd emerged from her anus, pushing out of her and into you - the diaper! it was semi-solid and more than one came out of her before she felt that she was done pooping and leaned back, which smooshed the poop all over her behind and the diaper - it was awful as you could taste it and it was not pleasant. the girl began to cry at this point and the mother took notice. "oh honey! you didn't?!" said the mother. "Don't worry, I'll change you...."
