Well then Katie, since you wanted to be a diaper I'll see to it that you get put to goo use, I think Zoe could defiantly use you wouldn't you agree? I can't wait to toss you out with the rest of Zoe's dirty diapers." Tiff asks with a evil grin, meanwhile Katie wants to scream she wants to change back not be put to use as a diaper, she realized this was the worst idea she ever had, "well of course you do that way you change your self in to a girls diaper, I'm sure the experience will full your dirty fantasy," she finishes with a smirk. Then transports them to Zoe's room, only to find Zoe fussing over a wet diaper, "well it looks like were just in time Katie, Zoe's ready for you now aren't you excited, I know I'm." Tiff lays Katie down on the change table, at the front of the change mat, before disappearing from Katie view for a moment as she takes Zoe from her Crib, and lays her down in the middle of the change mat, Katie, is unable to do any thing but stare forward between Zoe's legs as she watches Tiff carefully unfasten the wet nappy and clean her sister up with a couple of wipes then fold the nappy in half before dropping it into the pail beside the change table, "well Katie it looks like she only wet her self this time, maybe she'll mess her self next time, I'm sure you'll enjoy that, you'd just love to have her unload a nice big load of her messy poo in to you wouldn't you?" laughs Tiff as she grabs Katie an and pulls her up between Zoe's legs spreading her out before quickly lifting Zoe's butt to rest on Katie's padded face, while Katie is helpless to stop the horror her best friend is about to put her through, then she thinks about why she chose to change try changing into a diaper, how shes always be fascinated with dirty diaper's how even just last night she'd sung in to Zoe's room to play this some of her diapers, but she'd only rubbed the out side of them against her face, sure she though about don't more but was too much of a chicken to try it, just maybe this wasn't some horror but a dream come true, but what about when Zoe was done with her what would happen then she didn't want to be just thrown out. While Katie had be thing about this Tiff had finished wrapping her around Zoe and fastening her in face, "Well have fun Katie, I'm sure you'll enjoy this more then your activities last night, you can't chicken out this time so you'll get to enjoy the full experience. Yes Katie I know all about your dirty fantasy. But I do hope you enjoy becoming trash as I've made you change permanent side I do need to get rid of you." Katie is both shocked and horrified to learn that Tiff knows all about her interest in dirty diapers, but shes even more horrified when she realize that she was soon going to be thrown out like a piece of trash, unable to do anything, the boredom would be problem. Katie realizes she made a serious mistake, sure it might be fun to be used as a diaper by Zoe but only if she could change back and forth.
Zoe sleeps restlessly in her crib, she hears foot steps as Tiff comes in to the room, Katie feels like shes on a roller coaster as Tiff picks Zoe up, then she feels Tiff finger press in to the front of her checking to see it Zoe is wet, "well Katie it looks like Zoe hasn't used you yet, let hope this bottle helps, I'm sure the suspense is just killing you." Moments later Katie feels a had close around her and Zoe start to squirm as Tiff, feeds her the bottle, then half way through the bottle it happens, first it just a few disjointed spurts of urine, as Zoe starts to pee, they splatter against her face as she forced to soak it up through her mouth get to experience the full flavor of Zoe's piss, and Katie finds that it tastes really nice, even better then smelling it it still has that thick richness that the sent has but with the added spicy of a salty tang, Katie decides it the best thing she ever tasted and if she ever gets out of this, she going to take up sucking pee out of wet diapers, even the warm wet feeling of the pee against her face feel nice she just knows we would enjoy rubbing her face around the inside of a nice soaking diaper, but the experience only get better as Zoe moves on from short spurts to a continuous stream forcing her piss down her mouth causing her to flooding across her face with is cozy warmth Katie finds her self becoming aroused by the use to which Zoe is putting her making her wish she was her self again but with a guy laying over her, rubbing soaking wet diapers into her face as he fucks her senseless, it would be just perfect the ultimate experience she thinks to her self. All to soon Zoe finishes up leaving Katie soaking wet, but without the stream piss pressing against her the experience tapers off leaving her wanting more and wishing she was human again so she could explore her fantasies with some of Zoe's wet diapers, before remembering that Tiff plans for her to go our with the trash she realize with horror her fun is almost over and hellish boredom about to come. "Well it looks like the bottle help Katie, well mostly but I think we can wait to change her for a bit maybe she will still mess you."
Katie dosen't have to wait long before a sticky mass of shit erupts from Zoe's ass, with a rich creamy flavor like burnt cheese, Katie's arousal kicks into overdrive as she enjoys the experience of containing Zoe's shit, she wishes she could experience this wonderful use over and over, not just be thrown out with the trash. "Well it looks like you got to enjoy Zoe's mess, aren't you luck, I guess your just trash now, since Zoe really needs a change" Katie Mentally cringes at the last comment, she doesn't want to be trash, sure being fill of piss and shit is nice and relaxing, but their's no more excitement, to be had she just knows she'll get bored in the trash, then what, how long would she live for don't diapers take hundreds of years to break down that would be horrible, to spend so long just buried with the other diapers unable to move or do anything, shed go crazy from boredom in less than a month. Katie feels pressure at her back as Tiff, lays Zoe down on the change table and begins to unfasten her, front above Zoe, falling against the change table she finds she misses the pressure from being press against Zoe's body, the lack of pressure takes away from the feeling of being full. Then she watches as Tiff drops a few poo smired baby wipes into her after using them to clean Zoe up, before folding her in half and finishing cleaning Zoe doping the remaining wipes on top of her before folding her over again and tossing her in the the diaper pail, she lands in the bed of wet and messy diaper's with which she shall spend the rest of her life. Over the rest of the day she is buried in several more of Zoe's dirty diaper's, and slowly the pressure increases over the next few days as the bin full up. Until she hears Tiff again, "Guess what Katie, it's time for you to go out with the trash you and your new friends as all sealed up in the trash bag and collection day is tomorrow enjoy your new life, Not!"
