A father wants the best for his son

This father, like any other, always wants the best for his son and he is in charge of giving it to him. the very pig does not approve of any of his son's partners because he thinks that none of them is going to fuck him as well as he does. at this moment a doubt arises ... is it a selfish act because he wants to fuck him alone or is he just not thinking that anybody is going to give him as much pleasure as his father?
