Jeremy sits there and starts crying, and realizes he has another feeling. He has to take a dump.
He can't get to the bathroom, and goes right in his already-wet diapers. He feels the poo slide out of him, and the warmth against his bottom makes him want to keep going.
He pees again, making the poop mush against his bottom. He squeezes the last of the poop out, and sits on his bottom. It goes around his tiny dick, and makes his whole bottom warm and nice feeling.
His sister was looking for him. She called out to him, and opened his door to find the two year old Jeremy writhing in his own waste.
She's confused, and picks him up. Jeremy, liking the contact, pees again in delight.
His sister hasn't had to take care of a child, and doesn't know what to do. She sets him on his bed, and notices all of the clothes around her.
She likes them, and decides to put something on as well...
