It's not ethical at all. Mom is a family member, and the relationship is based on natural family bonds, not something to be 'trained' in an improper way. Such an idea goes against the norms of healthy family relationships and basic moral principles.

It's really not common at all. Spanking by anyone other than your own parents is quite rare. Friend's moms usually would just talk to the child, call their own parents, or use other methods to correct behavior. For example, they might make the child sit quietly for a while or do a small chore as a punishment instead of spanking.
My mom's friend took me to a park once. We fed the ducks and had a long walk. She told me about her travels around the world, which was really inspiring. It was a great day full of new experiences.
The most interesting thing was her collection of old books. She had a whole room filled with books from different eras. It was like a little library. Whenever we visited, she would show us some of the rare books and tell us stories about how she got them.
One could write a story about making mom 'mine' in the sense of having a really close and unique bond. For example, a child might work hard to win a school competition just to make mom proud. It could be a story of how the child overcomes difficulties and in the end, has a beautiful moment with mom that cements their special relationship.
Another motive could be revenge. Maybe he has some grudge against the son and he thinks blackmailing the mom is a way to get back at him. He figures it will cause chaos in the family and make the son unhappy.
