Jill a 17 year old teen aged girl was bored and clicking on random links on the net when she found an ad for an exciting adventure program for young couple between 16 and 19 years old, thinking maybe its something I could do with Jim we're the right age after all she clicks on the link and is taken to a government website. The website describes a special program seeking young people to go on exploration missions through a portal, similar to a stargate, which excites her given shes always likes the TV series so she continues reading, and learns since they have no idea whats on the other side the volunteers will be augmented by a process that only works for people under 20 years of age. Reading about how this process would make them effectively immortal shes decides to convince Jim they should sign up for the program.
Jim a 16 year old boy with a diaper fetish, was a home reading an sci-fi novel laying in bed wearing nothing but a soggy adult diaper, a fetish he still hasn't gotten up the nerve to mention to his girl friend Jill, when she excitedly barges in with out knocking like usual, he quickly pulls the covers over him trying to hide the diaper cursing "You can't just barge in like that Jill, I could be naked."
"I don't see why that would be a problem, I'm your girlfriend after all, besides I think I prefer the diaper," she giggles thinking about how fun it would be to change him.
"What diaper?" Jim asks nervously, scared that she caught him.
"The one you just hid under your covers when I came in," she giggles pulling them off him to expose the soggy diaper, "it looks nice and wet I so want to change you," she says with a sexy grin, causing Jim to blush bright red with embarrassment over being caught before realizing what shes saying and blushing even brighter when he realizes she aroused by him wearing the diaper.
"Oh" Jim replies even more nervous, given their never done any think more than kiss before, its wasn't that he didn't want to nor her not being ready no he was scared he would be good at sex and would end up driving her off.
"But before we get to that, I found this really good program for us to join, its being run by the government they want young couple to explore new worlds through something like a stargate, we so have to sign up."
"But wouldn't that be dangerous?" Jim asks being very risk adverse.
"Nah, they sorted that out they have a way of making us immortal so theirs no risk, but it only works on young people."
"Ok, I guess we can do it if your sure its safe," he stutters, "your really OK with me wearing diapers?" he asks.
"Sure I think its hot, but new rule for when you wear them your not allowed to take them off, you have to ask me to change you. Oh an enough avoid having sex because your scared of doing something wrong." she says assertively, going over to his closet and searching through it until she finds his diaper pail and clean diapers, she moves the pail over next to the bed, and places a clean one on his bead side table. She strips after locking his bedroom door, causing Jim's gaze to keep flitting between her breast and pussy with obvious desire in his eyes. She climbs on to the end of his bed lowering herself on to her knees, she leans forward inspecting his soggy diaper closely before giving it a sniff, "you certainly did a good job with this one, and your piss smell so good," she says in a husky voice. Before releasing the tabs and folding the front of the diaper down between his legs to reveal the wet yellow stained interior, she then lowers her head right into his groin to lick him clean managing to get his piss allow over the face. After licking up the piss, she takes his cock in her mouth and runs her hands over his balls mumbling "you taste so nice," as she sucks him off with the wet diaper still laying under him. Jim's cock already erect just from her changing him, quick starts to jerks before as he, they both moan their pleasure, finally Jim lets out a scream as his cock give a finally jerk blasting his cum into her mouth and down her throat before they both relax with Jill's face landing right in the middle of Jim's soggy diaper, she lets out a few more moans before running her face up along his groin then his chest as she crawls up the bed until finally her piss covered face is level with his and she plants a kiss on him giving him a taste of his own piss and cum as she rubs her pussy against his cock. It quickly jumps to attention ready for another go, causing her to lowering her pussy down onto his cock before gyrating her hips to roll her pussy about his cock causing him to give weak thrust up into her until they both explode in orgasm, leaving Jill laying on his chest completely spent. After a few minutes Jill slides back down his chest returning to a kneeling position between his legs, pulling the used diaper our from under him and warping in up she toss it in his diaper pail taking a big whiff of the contents. Finally she grabs the fresh diaper and puts in on him.
The next day they both head to the closet military recruitment center to sign up for the exploration program. After signing up they are loaded on to a military aircraft and taken to the top secret base where the portal is located to under go augmentation, a process which takes two weeks before they are fully recovered and ready for their first mission. They under go 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. Finally they head through the portal arriving on the other side on a soft bouncy surface, as they look around Jim asks "Where are we?"
"I don't know" Jill responds, "It kind of looks like a teenage girls bedroom" she points out several items, "but it can't be its far too big."
That is when the rooms owner enters through the door, "Or maybe were just really small" Jim says pointing at the massive girl.
"No we can't be the air is normal," Jill responses, "I think we just found a world of giants, judging by her size comparably we would be about the size of Lego characters, and I think we're on her bed"
"Oh that sounds bad" Jim says wondering what their going to do as he notices her heading their way, "look she coming our way."
The giant girl leans over the bed looking at them she notices they look like mini people and that their alive she gets an evil grin on her face as think thinks of different nasty things she could do with them, "Hello little people, just want shall I do with you" she reaches out and picks them up theirs just so many amusing options. "How about I ..."
