Write a long dialog between father and son. It started when the father had an upset stomach and wanted to go to the toilet. But the man forced the father to state his need to defecate in obscene language, otherwise he would not be able to use the toilet. The father was angry but forced to agree. When he went to the toilet, the son asked to come in to see or else he would not let him defecate. The father was so angry that he accidentally said that the son can do whatever he wants. Therefore, the son touched his father's butt and cock, and even forbade him to wipe his ass.
