"Well then Katie, since you wanted to be a diaper I'll see to it that you get put to goo use, I think James could defiantly use you wouldn't you agree?" Tiff asks with a grin, meanwhile Katie wants to scream she wants to change back not be put to use as a pair of Dry Nites, she realized this was the worst idea she ever had, "well of course you do that why you change your self in to a teen boys diaper, I'm sure the experience will full your dirty fantasy," she finishes with a smirk.
Then transports them to her room, walking across the hall to James room, she bangs on the door until he answers, "What do you want Tiff?"
"You know how you have those dirty fantasies about Katie?" she asks him, causing his face to flush red with embarrassment "and then you also have that bed wetting problem."
"Go away Tiff, leave me along" he begs.
"Oh I'm not teasing you, you see Katie turned her self into a diaper" she says holding the Dry Nites up for him to see, "and I was thinking since she obviously want to be use as a diaper and you have those fantasies about her along with the bed wetting problem its all just perfect, you can use her tonight and fill some of both of your fantasies."
James snatches the diaper away from Tiff, "Enough with your jokes about my problems, Tiff, or I'll tell mum."
"Fine don't believe me then"
"How would she even turn her self into a pair of Dry Nites?" he demands
"Well its a long story, but I got this magic power to make things happen," she demonstrates by making his pants disappear, "and Katie ask me to give her the ability to change into what ever she wanted and this is what she changed into," she finishes while James gapes at her shocked at her power.
"You weren't joking, but how do you know she wants to be used?"
"Why else would she choose to remain a diaper?"
Then she thinks about why she chose to change try changing into a a pair of Dry Nites, how she's always be fascinated with dirty diapers how even just last night she'd sung in to James's room since he was out, to play this some of his soggy diaper, but she'd only rubbed the out side of them against her face, sure she though about doing 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 James was done with her what would happen then she didn't want to be just thrown out.
Tiff shiff her gaze to the diaper saying "Well have fun with James, 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." Katie is both shocked and horrified to learn that Tiff knows all about her interest in dirty diapers.
"What activities last night?" James asks
"I caught her rubbing her face against your used diapers"
"Oh, so that's why you think she must want to be used since shes changed her self into a diaper?" James responds closing the door.
Removing his underwear, James lows the Katie the Dry Nites to the floor opening them up giving her an eye full of his partially erect cock, as he steps into her and pulls her up until she's pressed snugly against his groin his erection pressing in to her, Katie can well it like he's pressing his groin and erection into her face.
