Jake and Rachel had been dating for years since Rachel's family moved in to the house next door to Jake's the day before her thirteenth birthday, only to find it would be Jake's thirteenth birthday as well. Since she was new in town and didn't have any friend yet, Jake suggested they could share the birthday party his parents had planned. It was less than a month later when they lost their virginity together and from there they never looked back, usually having a sleep over at one house or the other every weekend, while their parents just assumed they were best friends, they where usually snuggled up in bed and playing sex games. However even now five years later, Jake still hadn't told Rachel about his secret fetish for dirty diapers stolen from the trash to scared that if he did she wouldn't want anything to do with him ever again, lately he'd been enjoying the fact that his older cousin had recently had triplets and he always like to help out especially when they need someone to help change the babies, he loved cleaning up their mess, and watching as the dirty diapers were pushed into the diaper genie where they were sealed inside a continuous bay by a self sealing mechanism, he often fantasied about being some how shrunk down and push inside with Rachel and the diapers, what his cousin didn't know was that Jake had manage to rescue all the diaper logs from her trash to play with. Recently he'd been debating telling Rachel about his fetish in the hope she'd be willing to play with him in the dirty diapers. But today they were searching for possible Jobs now that they had finished High School, that they could do while doing further study. They were both excited when they found the exploration job being offered by the military, after reading about how they would be augmented and send through a portal to explore a unknown world they decide it was perfect, and signed up right away.
Two weeks later they have undergone augmentation and are ready to go on their first mission, Jake has finally decide he will tell Rachel about his fetish, after they get back since they will be moving in together than. However it was not to be after under going the finally briefing where they are reminded that the portal will reopen monthly for 12 months only and that they can't take any thing through outside their bodies. They head through the portal arriving on the other side in a dark cavern on what seams to be a thick plastic surface, what's strange is the the it seams to be crinkled and on a slight slope down to a crack where their appears to be another sheet of crinkled plastic running down into the crack. "Where are we, this is very weird," questions Rachel.
They continue to look around find that away from the crack the plastic starts to slope up becoming too steep for them to climb, they also note that the surface is somewhat flexible, the most interesting thing they discover is that the crack dosen't have two sheets of plastic going into it rather at the edges where it become to steep to climb the plastic wraps around making it clear their in some kind of massive flexible plastic tube and their siting onto of some kind of mechanism designed to seal the tube. As they investigated their eyes have slowly adjust the the tiny amount of light getting into the cavern. This allows them to notice that there is some kind of ridged cover right above them with a crack where light is coming in except for a single section where their is no light, also the plastic tubing which turns out to be a blue color is rolling out under the cover.
As they discuss where they are and what it might be for, Jake noticing Rachel's naked body starts thinking about sex, which leads him to his fetish which causes him to notice the similarly to top of his cousins diaper genie only hundreds of time bigger, he mutters "can't be its to big."
"What was that Jake, you have an idea."
"Not really, just though of something I know of that this is similar to but, this thing is a least a hundred times larger."
"What though, maybe you'll give me an idea."
"Ok, fine, my cousins diaper genie, has a mechanism st the top to seal the diapers inside, which is similar to this bowl we're in but it doesn't make any sense we'd have to like the size of Lego figurines, for that, and the airs pretty much the same as earth only slight different concentrations, so we haven't be shrunk some how," he says resentfully.
"Oh, yeah we can't have been shrunk, but why do you seam to resent that?" queries Rachel.
"Ar..., Oh wel..ll I'd been meaninging to tell yoou.", Jake mumbles, before blurting out "I have this fetish for dirty diapers."
"What was that?"
Taking a calming breath Jake proceeds to tell her all about how he plays with his cousins babies dirty diapers, and kind of wants her to join in, and then about his fantasy of the two of them being shrunk down and push inside his cousins diaper genie.
"Oh, Ok," Rachel says slowly taking in every thing he told her as a horrify solution comes to her giants, "well I kind of hope I find you fetish fun as well, because I think I know exactly were we are."
"Oh, whats it got to do with my fetish?"
"Well your comparison to a diaper pail makes perfect sense, in fact to perfect, the only problem is the scale, but if this world is populated by giants then that solves the problem of the scale, really its the only reasonable explanation thus we are trapped in the sealing mechanism of a giants diaper pail," Rachel explains.
"Oh when you put it like that its makes sense, don't worry I'm sure you'll love being buried in dirty diaper, its really a lot of fun playing with them." Jake says putting his arms around her to provide comfort. Just then the lid flips up giving the a view of the room, which what is clearly a change table with shelves filled with fold disposable diapers next to them confirming their location as they look up further they see a massive, but clearly young human women lifting a diaper from the table towards the diaper pail, as they get a better view of the diaper they see ...
