Having intercourse with one Wife in the Presence of another Wife

Q: Prohibitions and Permissions-23: A man has two wives in the same house and even has them sleep in one bed. He sometimes has intercourse with one in full view of the other. Is this permissible?

Answer: This is a shameless act and causes hurt to the one watching. It is also Haraam for the one wife to see the private areas of the other. The act should therefore be forsaken.
