Imagine that your mother tells you a story often.
What would you say?
Meine Mutter erzählte sie mir oft.
Meine Mutter erzählte oft sie mir.
I know that the temporal complement should go before any other one and that the object comes before the dative if it (the object) is a pronoun. In this case you have two pronouns and one temporal adverb, so according to the rule I should use the second sentence, which does not sound fine to me. I would be glad for some help.
