"Well Jeff lets change you back for a bit so we can talk." his mother says, before turning to the computer and entering some commands, Jeff feels him self changing back into a teenaged boy, but starts to worry when he realises he's naked and still inside the plastic bag, until he realise that its growing with him. Then He realises he still soaked in his sisters piss.
"Mum can I have a shower before we talk, I'm gross all over."
"No Jeff, were going to talk about how you can be more useful, first."
Jeff thinks to him self I need to give her something else to go after, then he remembers how Jess said she liked bed wetting and did it on purpose, he decides to sell her out, "How about we talk about Jess's flaw instead, like how she admitted to wetting the bed on purpose, because she enjoys it. Making you waste money on her when you don't need to." he says thinking to him self, "Their now she'll go after Jess."
"So what if I like wetting my self, we'll just turn you back into a new pair of goodnites, I can use you over and over." Jess laughs.
"Sorry Jess, can't do that, you see I need him to help with babysitting Cassie today, you known the special help he's good at, so you'll just need to use your existing goodnites."
"But mum, Cassie isn't coming over until the afternoon, can't I wear him for now and you change him when you need his help?"
"Oh I guess that's Ok, Love."
"What are you doing you can't do this to me?" Jeff demands.
"Actually we can, face it Jeff, you make a better nappy than you do a person." Jess says giving an evil giggle, "Oh and mum, I've got some ideas to improve him when you need his help with Cassie, and can I please be the one to change her?"
"Of course, you know I love it when you help out Jess, and I know just how good you are with computers. I'll just change him back so you can put him on again," his mother responds, hitting a few keys on the computer starting his change again.
"Well I'll go put him back on then, I'll be back and we can work on the program for his next change." Jess grabs Jeff and takes him back to her bedroom.
Back in her bedroom Jess again pushes her hand inside him spreading him out this time the angle given him a good look at her evil grin. Jeff watches on in utter dismay at his fate, as she slowly lowers him to the ground and steps forward into him and pulls him up her legs, as she finishes pulling him up the world to disappear into darkness as he press snugly around her ass and legs, leaving him pressed against her genitals, they rub against him as she walks out of her room back to the computer where she explains her diabolical plan for him, with him unable to any thing but listen on in horror as she describe her plans for his fate. "So Mum I think I can program him to under go a whole series of changes as conditions are met, so first we'll change him in to a fresh nappy for Cassie, but then after shes used him that when it gets interesting, at first he'll stay as he is, but once he been thrown into the bin things will get interesting, if hes just an isolated nappy, then nothing will happen he can stay that way, but if he ends up in a nappy bin, once hes all sealed up inside and properly buried in other used nappies with no chance of discovery, he'll change back but maintaining his size, and of course still covered in all her mess, now that could be all that happens, but if he ends up buried in enough used nappies to bury a full sized human, then he'll grow back to full size, but only if he'll remain trapped in all the nappies. Then as a fail safe, if he dose manage to sometime get out he'll just change back into a clean nappy and be transported to the top of the closer nappy pile, he'll obviously be of a matching type, all ready to start the cycle again. Actually I'll change that first scenario, if he gets tossed out on his own into regular trash, he'll just change into a fresh nappy after say 24 hours. So what do you think mum?" she asks while she continues typing away at the computer.
"Oh it sounds perfect, just one thing what if Cassie uses him before she goes home?"
"Oh that won't be a problem, I can just reset him and put him back on her so she can use him again."
"Excellent, so were all ready to go?"
"Yes just need to set his initial size and type her then hit enter. Now I need a drink, so I can full him up again before Cassie needs him."
Nothing much happens for Jeff for the next couple of hours, as Jess goes about her day he can of course feel her movements, and when she sits down, but not much else. Eventually though Jess needs to piss again, "Hey Jeff guess what your so luck, I need to pee again," she giggles, as she just starts to piss in him right then and their, for Jeff, he hears her moments before a disgusting wet warmth start spreading across him once which he can't help but enjoy just like the fore, he hates the way he enjoys every thing about her pissing in him, the way it spreads over him, the way he soaks it up, the flavor and smell, and especially the nice cozy warmth, "Too bad Cassie gets here in half an hour, I won't have long to enjoy you like this, but I will enjoy knowing whats awaits you then." The next half hour passes slowly for Jeff as Jess keeps wriggling and playing with him with her hands, much to his dismay, both his disgust and enjoyment increases over that period.
Then he hears crying, and his mother calls out "Jess, Cassie needs a new nappy now."
"Just a moment coming she calls" she quickly rips Jeff off and puts her pants back on, before picking him up and carrying him back to the living room, where Cassie, and the computer are, "Hey mum what type of nappy dose Cassie use?"
