Step-Mom? Is it Possible?

My ultimate fantasy would have a real Step-mother figure. A woman who was older and believes spanking is an important part of discipline. The ideal person would live alone, raised her family, needs some company, and have a nurturing personality. Also, the type a person you like being around with no sexual interest in whatsoever. I picture showing up 2-3 times a week and talking, leading to the occasional 1-2 spankings a month for real offenses.

Am I crazy? Does this only exist in my mind? Has anyone had a experience like this? Please give me some hope... advise... Thanks B
