"What are you crazy, we have to find a way out of here, before my dammed sister buried us in her waste," screams Alex.
"How? Why? You know we can't get out nappies are designed to contain whats inside them, besides why would we want to is fun when she pisses on us. And if she buries us in shit she'll just throw us out whit the nappy when she changes her self, then we'll have a whole bin's worth of shit and piss to play with," argues Hoshi, "now can we please get on to the sex, the whole reason Cassie put us together is so we can play with each other when we get thrown out." As she slide down his body so her face is level with his.
"What?" Sputters Alex, "You know Cassie? What do you mean get thrown out?"
"Yeah me and Cassie have talked a lot shes really smart for her age, did you know she doesn't need nappies she just likes using them? Anyway you do know that we can't die don't you? And you know that if the staff find us in a used nappy we get thrown out with the nappy? Except Cassie changes her self, so when she pees of me she switches me over to her new nappy, so we can have some more fun. Well she brought you here so I could have a guy to play with, like the idea of being thrown out wrapped up in a used nappy is so hot and all but there only so much fun you can have on your own, that was my only worry the for but now I don't have to worry because Cassie's going to make sure your there to play with me when I get thrown out with the dirty nappies. Its going to be so much fun, she just has decide exactly how to go about it." Hoshi stops for a moment rubbing her pussy against his crotch before continuing "So she can arrange for us to be eaten by one of the kids or her self, then we get a tour of the digestive system, before being caked in shit as we pass through the big intestine and then push out with the rest of the shit into a nappy ready to be thrown out, or maybe a potty depending on the kid, ever way we end up in the bin along with the rest of the dirty nappies and emptied potties, on the other hand she could keep us as her own personal play things transferring us to nappy after nappy maybe even for ever, or just toss us out in her own dirty nappy, then she could put us in one of the other kids nappies, some of them do a real good job of messing their nappies at regular times each day, lots of different options there, depending on the type of mess were after, do we want logs, lots of little balls, paste, or runny soup?"
"What the heck is wrong with you? How can this excited you?" demands Alex.
"Whats it matter, its happening, out fate is completely up to Cassie, she may ask for input but she decides what happens to us, there nothing we can do, get use to the idea and enjoy it now would you please stop talk and fuck me." she finishes by rubbing her whole body against his leaning in to his face and kissing him, her breast pressed against his chest rubbing their nipples together and her pussy pressing against the tip of his erect cock.
Alex find him self unable to hold back form his arousal and slams into her pressing her against the inside of the pull-ups, soon hes completely into fucking Hoshi, his tongue invading her mouth and hands cupping her ass, as he ruthlessly pounds in to her eliciting moans of pleasure from Hoshi. Alex pounding away at Hoshi also cause stimulation to Cassie, while it's not really sexual, it dose feel nice to her, Cassie know from stuff shes read online that its the stimulation of her immature sexual organs, and that when she older such stimulation will do a lot more than just make her feel nice, but lead to sexual arousal, but for the moment she just enjoys the sensations, and lets loss a torrent of piss quickly flooding the front of the nappy, and thoroughly soaking Alex and Hoshi, pulls the front open looking down she asks "You two having fun in there?"
They respond at the same time Hoshi simply saying "Yes", but Alex responds with "Until you ruined it."
"Well I'll have to change my self in a bit but what should I do with the two of you, throw you out or something else?"
