shorts

Q: My wife's father demands from her to massage him and bath him while he is just wearing bermuda type shorts. He ignores her condition or tiredness. I want to know if it is allowed for him to demand this service from her? Am I justified forbidding her to do so? He lives in another city and keeps on insisting for her to come there, totally ignorant of the fact that she has a job and kids to look after. Now he is demanding to move in with her just for the reason that she may serve him like that. He has a wife who is my wife's step mother. I do not like her massaging or bathing him in his semi nude condition, but my wife said that its a culture of their country.
