Of course the girl doesn't seam to give a care in the world for the fact that shes just soaked her nappy, Greg wishes she would, maybe if she just wet when they change her they'll just wash him off, but even if they down being thrown away in a wet nappy is better than a messy nappy, hell being in the wet nappy isn't actually that bad, its warm and cozy he can actually understand why shes not upset he can feel the wet nappy pressing against his back it feels nice, then for him the taste and smell of her piss is actually rather nice, he remember reading about piss play as a sexual act, he figures if he ever gets out of here he'll have to try it out, not that that's very likely.
Then as the girl starts to fart regular Greg knows hes doomed, he knows just what that mean, that it about to get messy in here real fast.
In fact its so fast he doesn't even have time to think before it happens and a soft sticky mess pushed down against his stomach pushing him out of her bum crack, but it doesn't stop there the sticky mess continues to grow spreading over and around him quickly filling the already soaked nappy, what surprises Greg the most is that her shit doesn't stink like he expected it has a rich damp smell like old condensed milk that's been slightly burnt, mixed with the smell of fresh compost. Then as some of the shit force it way into his mouth he discovers it actually tastes wonderful, like a rich creamy chocolate cheese with several spices thrown in. As he thinks about how nice it tastes he horrified that he finds the babies shit as something that tastes nice.
