I am not sure whether the word "and" needs in the following sentence I created:
I studied all the time after my mother returned home (and) until my father returned home.
Could anyone give me advice !

It's stilted. You're describing an interval of time - use from/to or from/until. After/until is not a normal pairing.
I studied from the time my mother returned home until my father returned home.
No, it's not needed. Using "and" in the sentence makes it sound incomplete; as if another action was expected. For instance, "I studied all the time after my mother returned home and until my father returned home, I coudn't stop."
I would write it like this.
In the time after my mother and until my father returned home I would study.
There is no need to repeat "returned home" twice, I think that is the mistake not the "and".
