The boy scopes them up with a bag made from a fine mesh, before sealing it shut trapping them inside, then he says, "don't worry guys I known just what you need we just have to wait until school finishes then I'll help you out." before washing them off and dumping them in the side pocket of his backpack, where he leaves them for several hours.
Finally he takes them out as he's walking across the road from the school and down a path, "hey guys I'll be able to help you out in just a bit, I'm just picking up my stepsister Lake, from daycare on the way home," he says as he places them in his shirts pocket. Just a few minutes later they hear him saying "hello, I'm River, Lake's brother, I'm here to collect her." then a bit later, "hello Lake how was you day did you have a good time? I've got some new friends to show you."
A minute or two later he pulls them out of his pocket again revealing him now carrying a diaper bag over his left shoulder and a six month old giggling baby girl, held against his right side, "hi guys, this is Lake my little sister, Lake these are our new friends," finishing up with an evil grin, "now I'll let the two of you get acquainted with Lake," unsealing the mesh bag their in and moving to the back of Lake's diaper.
"No Don't" they scream out together, but to no avail as he pulls open the back of Lakes diaper and empty them down inside it before letting the back snap back into place sealing them inside the little girls diaper. The first thing the notice is how warm and humid it is inside the diaper, in fact if it wasn't for the fact they were siting inside some little baby's diaper it would actually be rather cozy, next is the odor a mixture of baby powder and sweat which doesn't actual smell bad exactly though it is really a pleasant smell either.
They then hear Lake giggling "diapee friends diapee friends," as she bounces in his arms clearly excited to have little people in her diaper.
"Yes Lake, diapee friends, and you know what we do with diapee friend, we welcome them with a nice phooey in out diapee" River says with a nasty smirk in his voice.
They then hear Lake still giggling and bouncing away "phooey phooey in diapee, for diapee friends" over and over.
"Now what?" Jim questions, "I don't think we can climb out especially with her bouncing away like this."
"No your right, we just have to wait and hope, maybe she'll lay down for a nap before using her diaper, then we can crawl out of here."
"But what if she uses the diaper first?" Jim demands.
"Weren't you saying a girls piss would be fun to play in earlier Jim?" Jill teases back.
"Ar I mean a teenage girl, you known like you not a little kid, and beside what if its not just piss, what if she makes a mess, we be buried in it."
"Well I don't have any other ideas for escape, so if she makes a mess its not like there anything with can do but wait to be thrown out. Actually the idea of being sealed up in a phooey diaper with you sounds kind of um Hot, I think I'd like to try have sex like that, maybe we shouldn't try to escape at all," she giggles.
"Jill" screams Jim, "That an artful idea we have to escape, it sounds totally gross!!"
"Ok I was joking about the not escaping part, but it dose sound kind of hot."
