A Story With No End!

Stuart loved listening to stories. He used to listen to stories on his phone many times. His grandparents used to tell him a story every day. But he wanted to listen to a story that is never-ending. Stuart's parents were very very rich. They called a man named Jason who was pro in storytelling. Stuart said to him to tell him a story that is never-ending. Jason thought a little bit and said," Okay I'm going to tell you a story which will never end! So the story starts as follows:

Once upon a time, there was a king named Grorkh. He loved his people. So he used to bring hundreds of kgs of sacks of grains so that he would distribute them every month to every citizen of his kingdom. Every month new sacks used to arrive in the king's Kingdom and he used to store them in a storehouse, where many naughty mice were present. They used to bite the sacks and the grains in the sacks used to fall because the sacks were torn or bitten by mice. The wall of the storehouse was also broken. It had a hole. A little sparrow saw that hole and entered there. It saw many grains there, It picked a grain in its beak and ate it. It flew and told to another bird about the free food."What happened then?" Stuart asked. Another bird picked up the grain then it told others about it. Then they also came and picked up the grain. "Then"? Stuart asked. Then those birds told to other birds about the grains and they also came and ate them and they told to others and to others and to others!!

In fact, Till now Jason is telling the story to Stuart! Can you tell where Jason reached till now?
