Should Kody Brown's wives have brother husbands? That is the question the polygamist family is asked and answers in the next episode of Sister Wives.

After the Brown family accepts an invitation from a religious professor to talk to her students in Boston, they're anxious about what questions or even accusations they might face during the Q & A panel.

And at the top of the list -- why should men have all the fun. Why shouldn't sister wives have brother husbands?

You'll have to tune in to TLC Sunday night at 9/c to hear their answer.

But you can catch a sneak peek at the episode here on Breaking Celebrity News.
