One possible reason could be that the boy did something really naughty like breaking a precious family heirloom. Maybe he was playing ball in the house and accidentally knocked over a vase that had been passed down for generations.
One reason could be that the aunt has very strong traditional views on discipline. She might believe that spanking is an effective way to correct bad behavior immediately and doesn't think twice about doing it in front of the mother. Another reason could be that she is over - reacting in the heat of the moment, especially if the boy has done something that she finds extremely unacceptable.
Often in such stories, the child might have been acting recklessly. For example, playing with something dangerous that the aunt had specifically told him to stay away from. Another reason could be that he was being disrespectful to his aunt, perhaps talking back or not showing proper manners. This would lead the aunt to feel that a spanking was necessary to correct his behavior.
Maybe the child was naughty. For instance, if the child pulled the cat's tail, which is cruel and wrong. The aunt, being an adult in the family, might have decided to spank as a form of punishment.
One possible reason could be that the boy has seen this as a form of discipline in his family or in some media and he thinks it might be a way to correct his mistakes at school. Maybe he has done something wrong and he feels guilty, and in his mind, a spanking is a way to pay for his misdeeds.
He probably cried a lot. Spanking can be quite painful for a young boy, and the shock of being disciplined in such a way might have made him burst into tears immediately.
Another reason could be disrespect towards elders. In a family, if a teenage boy shows disrespect to his parents or grandparents, such as talking back rudely or making fun of them. This behavior is often not tolerated in many families, and as a form of discipline, spanking and mouthsoaping might be used to teach the boy to respect others.
One possible reason could be a sense of extreme guilt. The boy might have done something really bad, like cheating on a major test or bullying a fellow student, and he feels that a spanking is the only way to truly atone for his actions. Another reason could be that he comes from a very traditional family where spanking is seen as a normal form of discipline, and he expects the same from his teacher.
It could also be due to a strict upbringing. If he has been taught that misbehavior should be severely punished, he might internalize this and when he feels he has misbehaved, he starts self - spanking. For example, if his family has always emphasized strict discipline and he has grown up believing that any small mistake is unacceptable, this could lead to such extreme self - punishing behavior. Moreover, in some cases, it might be related to low self - esteem. If he constantly feels unworthy or bad about himself, he might use self - spanking as a way to 'correct' what he perceives as his flaws.
One reason could be that he has a medical condition like incontinence. Some kids might have bladder or bowel control issues that require them to wear diapers, and he might be self - conscious about it and trying to hide it. Another reason could be a form of comfort - wearing a diaper gives him a sense of security similar to when he was a baby.
One possible reason could be self - punishment due to feelings of guilt. Maybe he made a mistake and feels like he needs to be punished in a more extreme way than normal.
