The "women" closest to him were his mother and sister. The son and brother, who were interested in sexual intercourse, broke the taboo of incest in order to satisfy their own sexual desires. They spread a nice scent around the house, walk around in their underwear, and are defenseless and unguarded by their mother and sister, who are not conscious of themselves as men. Their desires cannot be suppressed, and they agree, or they commit incest by any means possible, including sleeping with them.
